    Childcare and maternal employment in Europe: How childcare cost differences among European countries influence the labour force participation of mothers?2016Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The aim of this essay is to examine the influence of childcare costs on mother’s employment in European countries. Previous literature indicates that having a child represents a penalty for a woman’s career and integration into the labour market. An empirical analysis has been conducted using the OLS method and cross-national data. We have focused our study on 17 European countries and on data from one particular year.Our findings suggest that a high childcare cost is related to a low maternal employment rate and/or a high share of employed mothers working part-time. As a result, the variations in childcare cost may be partly responsible for the variation in mother’s employment across European countries.The main limitation of this analysis is the small number of observations. Due to the lack of statistical significance of most of the coefficient, we can only suggest a hypothesis that needs to be investigated by further research.

    The real exchange rate, foreign aid and macroeconomic transmission mechanisms in Tanzania and Ghana2013Rapport (Annet vitenskapelig)
    Abstract [en]

    A recent study of 36 sub-Saharan African countries found a positive impact of aid in theabsolute majority of these countries. However, for Tanzania and Ghana, two major aidrecipients, aid did not seem to have been equally beneficial. This paper singles out these twocountries for a more detailed empirical investigation. The focus is now on the effect of aidwhen allowing external and nominal factors to play a role in the macroeconomic transmissionmechanism. We conclude that aid played a significantly positive―but very different―role inthe two countries. Due in part to generous aid inflows Tanzania experienced positiveinvestment and GDP growth from the late 1960s to 2007. But, until the mid-1980s, theimpact of aid on growth was well below its potential as the large inflows of aid facilitated aserious over appreciation of the real exchange rate. In Ghana, declining aid in the 1970s wasassociated with lacking growth while the reactivation of aid flows in the 1980s supported aneconomic rebound. When monetary and external factors are properly accounted for, we findthat aid has been pivotal to growth in both real GDP and investment.

    Abstract [en]

    A recent study of 36 sub-Saharan African countries found a positive impact of aid in the majority of these countries. However, for Tanzania and Ghana, two major aid recipients, aid did not seem to have been equally beneficial. This study singles out these two countries for a more detailed empirical investigation. The focus is on the effect of aid when allowing external and nominal factors to play a role in the macroeconomic transmission mechanism. We conclude that when monetary and external factors are properly accounted for, then aid has been pivotal to growth in both real GDP and investment.

    Differences in Unemployment due to Sexual Orientation: Evidence from the Swedish Labour Market2018Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The present study provides the first investigation of differences in labour market outcomes by sexual orientation utilizing Survival Analysis techniques. A three-stage modelling approach has been utilized. Zero- Inflated Negative Binomial regression has been conducted to the duration in unemployment, while Probit analysis to the probability of employment. A parametric Gompertz baseline hazard has been determined, which enables us to fuse unemployment duration and employment event into one analytical feature. Significant differences by sexual orientation have been detected. Regarding employment probabilities, homosexual males face a disadvantage of seven per cent compared to heterosexual males, while the probability for homosexual females increases positively with the duration in unemployment. No significant differences have been found regarding unemployment duration. When unemployment duration and probability are set into relation, differences by sexual orientation vanish.

    Investigation of the time-dependent dynamics between government revenue and expenditure in China: a wavelet approach2019Inngår i: Journal of the Asia Pacific Economy, ISSN 1354-7860, E-ISSN 1469-9648Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Unlike previous studies on causal relationships between government revenue and expenditures in China, this study takes into consideration structural breaks in the data by performing wavelet decomposition prior to testing for Granger causality between the fiscal components. The use of wavelet decomposition is motivated by economic theories, which suggest allowing for different budgetary considerations at different time horizons, as well as by the existence of special properties in the data in the form of unit roots and structural breaks. The results from the Granger causality test when using the wavelet-decomposed quarterly data over the period 1980–2015 indicate that government revenue Granger-causes government expenditure (tax-and-spend hypothesis) in the wavelet scales of two to four quarters. The results also show that bidirectional causality (fiscal synchronisation) exists in the wavelet scale of eight to sixteen quarters. Understanding the causal relationships between revenue and expenditure at different time scales is important for formulating relevant policy measures in order to maintain fiscal sustainability in China.

    Wavelet quantile analysis of asymmetric pricing on the Swedish power market2017Inngår i: Empirica, ISSN 0340-8744, E-ISSN 1573-6911, Vol. 44, nr 2, s. 249-260Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this article we investigate if the Swedish consumer prices for electricity are adjusted equally fast regardless of whether the NordPool power market prices are decreased or increased. Due to relatively moderate variations in the variables, we have applied quantile regression, since it is mainly the large changes (above the median) that essentially tend to have a considerable effect on the consumer prices. Moreover, in order to adjust for stochastic- and deterministic trends, autocorrelation, structural breaks as well as to measure APT effects in the short- and in the medium-run, we apply a wavelet decomposition approach. Our results show evidence that significantly positive asymmetric price transmission (APT) effects exist in this market. More specifically, in the short-run (based on the wavelet decomposition D1 for 1–2 months cycles), we find that that there is a higher propensity to rapidly and systematically increase the consumer prices subsequently to an increase in the NordPool market price, compared with the propensity to decrease their customers prices subsequently to a corresponding drop in the NordPool market prices. However, no significant APT effects were detected in the medium- or in the long-run (i.e. the asymmetric price transmission effects are observed only in the short-run). In summary, we could isolate significant APT effects in the short-run (1–2 months decomposition cycles), and for large changes in the dependent variable (percentiles = 0.9). Therefore, only large changes in the NordPool prices lead to feedback effects in the form of asymmetric price transmission effects. Our evidence supports the notion of firms’ downward stickiness of retail prices for maximizing profit, which are not expected to be found on a fully efficient market. Although our finding shows that the price inefficiency is short-lived, these large temporal inefficiencies are still costly for the consumers. It should be noted that blunt traditional powerless methods do not detect these APT effects, while our wavelet quantile methods are powerful and make a significant contribution in the literature by providing new empirical evidence.

    The Causal Nexus between Oil Prices, Interest Rates, and Unemployment in Norway Using Wavelet Methods2018Inngår i: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 10, nr 8, s. 1-15, artikkel-id 2792Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper applies wavelet multi-resolution analysis (MRA), combined with two types of causality tests, to investigate causal relationships between three variables: real oil price, real interest rate, and unemployment in Norway. Impulse response functions were also utilised to examine effects of innovation in one variable on the other variables. We found that causal relations between the variables tend to be stronger as the wavelet time scale increases; specifically, there were no causal relationships between the variables at the lowest time scales of one to three months. A causal relationship between unemployment rate and interest rate was observed during the period of two quarters to two years, during which time a feedback mechanism was also detected between unemployment and interest rate. Causal relationships between oil price and both interest rate and unemployment were observed at the longest time scale of eight quarters. In conjunction with Granger causality analysis, impulse response functions showed that unemployment rates in Norway respond negatively to oil price shocks around two years after the shocks occur. As an oil exporting country, increases (or decreases) in oil prices reduce (or increase) unemployment in Norway under a time horizon of about two years; previous studies focused on oil importing economies have generally found the inverse to be true. Unlike most studies in this field, we decomposed the implicit aggregation for all time scales by applying MRA with a focus on the Norwegian economy. Thus, one main contribution of this paper is that we unveil and systematically distinguish the nature of the time-scale dependent relationship between real oil price, real interest rate, and unemployment using wavelet decomposition.

    Investigation of the nonlinear behaviour in real exchange rates in developing regions2018Inngår i: Applied Economics Letters, ISSN 1350-4851, E-ISSN 1466-4291, Vol. 25, nr 5, s. 335-339Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This article examines whether the purchasing power parity (PPP) theory holds or not for the economies in different developing regions located in Africa, Asia and Latin America. In order to investigate this issue, a nonlinear panel unit root test is used to determine if some or all of the real exchange rates in a panel follow a stationary exponential smooth transition autoregressive process. By applying the nonlinear panel unit root test, our results demonstrate an empirical support for the theory of PPP for the economies in developing regions.

    Getting a full-time job as a part-time unemployed: How much does spatial context matter?2014Inngår i: The annals of regional science, ISSN 0570-1864, E-ISSN 1432-0592, Vol. 53, nr 1, s. 179-195Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper investigates the extent to which differences in the probability to exit from part-time unemployment to a full-time job are accountable for by spatial contextual factors and individual characteristics. To correctly incorporate contextual effects a multilevel analysis applied using a mixed-effects model, a method frequently used in other disciplines but rarely used in economics, is adopted here to explore whether contextual factors account for differences in the probability of transition to full-time employment between individuals with different characteristics. The results indicate that there is a contextual effect and that there are some spatial spill-over effects from neighbouring municipalities, and unemployment rate partly explains the context variability. Furthermore, the contextual effect is found to be especially large for individuals without a university degree.

    Capitalisation of Single Farm Payment on farm price: an analysis of Swedish farm prices using farm-level data2014Inngår i: European Review of Agricultural Economics, ISSN 0165-1587, E-ISSN 1464-3618, Vol. 41, nr 2, s. 279-300Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper estimates capitalisation effects of farm attributes with a particular focus on the decoupled Single Farm Payment (SFP) on prices. The spatial analysis employs a sample of mainly small- and medium-sized Swedish farm transactions sold all across Sweden; the results from a spatial multiple-membership model suggest that decoupled SFP has no influence on farm prices. Prices are profoundly influenced by residential characteristics and accessibility to urban amenities. Spatial heterogeneity is found for both regional and local levels, and a large spatial spillover effect is found between neighbouring farms. Results are confirmed by sensitivity analyses.

    Do employers care about which school I went to?: It depends. Independent upper-secondary schooling as a signal of ability.2019Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    I investigate if employers sort job applicants based on information about whether the applicants attended a public or an independent upper-secondary school. I perform a stated choice experiment where real employers in Sweden are enrolled and asked to evaluate fictitious job candidates for a current job opening. I find no evidence of such signaling effects for candidates with a typical Swedish name. However, candidates with a Middle Eastern sounding name experience a probability of being invited to an interview that is 14-19 percentage points higher if their resume reveal that they went to an independent, in contrast to a public, school. I show that, under some assumptions, these outcomes can be explained by theories on labor market signaling. There exits very little empirical evidence on the relationship between school choice and sorting in the labor market. Consequently, these findings fills an important gap in our knowledge and brings new perspectives for educational policy.

    The global labor market for soccer players: Examining wage differentials between natives and immigrants in Sweden2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    This essay studies wage differentials between foreign born and native players in

    Swedish soccer. For this essay, panel data for the years 2001-2015 on all clubs and players in top Swedish soccer leagues Allvenskan and Superettan have been collected. The data is examined by applying a market-test approach to test for any significant wage differentials.

    The results show that foreign born players earn a significant salary premium compared to native players of similar productivity. There is no evidence of salary or fan discrimination against foreign born players. Results can be explained by market imperfections and/or risk-seeking behavior from team managers although this could be further investigated in future studies.

    Labor income inequalities in Swedish municipalities 1991-2017: A study on regional effects and possible origins2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Income inequalities have become a matter of major concern following reports that the working class and lower middle class of developed economies have income levels that are falling behind. Few studies have been conducted on the regional level even though this perspective might better capture the development of income inequalities, since national averages might hide local differences. This study uses panel data for 286 Swedish municipalities in between 1991-2017 and fixed effect regressions, to examine if the theory of a skill-biased technological change could be used to explain resent developments. We find an labor income divergence for Swedish municipalities within the studied time period. The share of high skilled workers is found to be a good predictor of the growth in regional labor income inequalities, while an ageing population of the regions falling behind counteracts the growth of inequality, possibly leading to an underestimation of the size of regional labor income divergence. These results are in support of a skill-biased technological change at work and a job polarization transforming regional labor markets and regional societies. We conclude that adopting a regional perspective in the analysis and development of future economic growth policies is necessary to ensure long term economic growth, equality of opportunity and social cohesion.

    Performances of model selection criteria when variables are ill conditioned2019Inngår i: Computational Economics, ISSN 0927-7099, E-ISSN 1572-9974, Vol. 54, nr 1, s. 77-98Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Model selection criteria are often used to find a "proper" model for the data under investigation when building models in cases in which the dependent or explained variables are assumed to be functions of several independent or explanatory variables. For this purpose, researchers have suggested using a large number of such criteria. These criteria have been shown to act differently, under the same or different conditions, when trying to select the "correct" number of explanatory variables to be included in a given model; this, unfortunately, leads to severe problems and confusion for researchers. In this paper, using Monte Carlo methods, we investigate the properties of four of the most common criteria under a number of realistic situations. These criteria are the adjusted coefficient of determination (R2-adj), Akaike's information criterion (AIC), the Hannan–Quinn information criterion (HQC) and the Bayesian information criterion (BIC). The results from this investigation indicate that the HQC outperforms the BIC, the AIC and the R2-adj under specific circumstances. None of them perform satisfactorily, however, when the degree of multicollinearity is high, the sample sizes are small or when the fit of the model is poor (i.e., there is a low R2) . In the presence of all these factors, the criteria perform very badly and are not very useful. In these cases, the criteria are often not able to select the true model.

    Does immigration affect native's labor market outcomes in Germany?2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Germany is one of the several countries in Europe that have opened its borders to immigrants for many years. The admission of immigrants into Germany has contributed to the country being the second largest immigration destination in the world, and this has resulted in both negative and positive outcomes for the natives. In this essay, the effect of immigration on natives’ hourly wages and employment was examined, by using microdata for Germany. Native workers’ educational level attainments and 16 different regions in Germany were taken into account to obtain regional variation. Cross-sectional data was used for the years 2005, 2009 and 2015 in order to measure the effect of the share of immigrants on natives’ hourly wages and employment. The findings showed that the share of immigrants, had a positive effect on natives’ wages and employment in 2005 and 2009. In 2015, however, a negative relationship was found, with the share of immigrants impacting negatively on natives’ wages but not on employment. Thus, the study highlights the importance of immigrants on natives’ hourly wages and employment.

    A Tobit Ridge Regression Estimator2014Inngår i: Communications in Statistics - Theory and Methods, ISSN 0361-0926, E-ISSN 1532-415X, Vol. 43, nr 1, s. 131-140Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This article analyzes the effects of multicollienarity on the maximum likelihood (ML) estimator for the Tobit regression model. Furthermore, a ridge regression (RR) estimator is proposed since the mean squared error (MSE) of ML becomes inflated when the regressors are collinear. To investigate the performance of the traditional ML and the RR approaches we use Monte Carlo simulations where the MSE is used as performance criteria. The simulated results indicate that the RR approach should always be preferred to the ML estimation method.

    Modified Ridge Regression Estimators2013Inngår i: Communications in Statistics - Theory and Methods, ISSN 0361-0926, E-ISSN 1532-415X, Vol. 42, nr 8, s. 1476-1487Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Ridge Regression is a variant of ordinary multiple linear regression whose goal is to circumvent the problem of predictors collinearity. It gives-up the Ordinary Least Squares (OLS) estimator as a method for estimating the parameters of the multiple linear regression model . Different methods of specifying the ridge parameter k were proposed and evaluated in terms of Mean Square Error (MSE) by simulation techniques. Comparison is made with other ridge-type estimators evaluated elsewhere. The new estimators of the ridge parameters are shown to have very good MSE properties compared with the other estimators of the ridge parameter and the OLS estimator. Based on our results from the simulation study we may recommend the new ridge parameters to practitioners.

    A simulation study of some biasing parameters for the ridge type estimation of Poisson regression2015Inngår i: Communications in statistics. Simulation and computation, ISSN 0361-0918, E-ISSN 1532-4141, Vol. 44, nr 4, s. 943-957Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper proposes several estimators for estimating the ridge parameter k based for Poisson ridge regression (RR) model. These estimators have been evaluated by means of Monte Carlo simulations. As performance criteria, we have calculated the mean squared error (MSE), the mean value and the standard deviation of k. The first criterion is commonly used, while the other two have never been used when analyzing Poisson RR. However, these performance criterion are very informative because, if several estimators have an equal estimated MSE then those with low average value and standard deviation of k should be preferred. Based on the simulated results we may recommend some biasing parameters which may be useful for the practitioners in the field of health, social and physical sciences.

    Some Ridge Regression estimator for the zero-inflated Poisson model2013Inngår i: Journal of Applied Statistics, ISSN 0266-4763, E-ISSN 1360-0532, Vol. 40, nr 4, s. 721-735Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The zero inflated Poisson regression model is very common when analysing economic data that comes in the form of non-negative integers since it accounts for excess zeros and overdispersion of the dependent variable. However, a problem often encountered when analyzing economic data that has not been addressed for this model is multicollinearity. This paper proposes ridge regression estimators and some methods of estimating the ridge parameter k for the non-negative model. A simulation study has been conducted to compare the performance of the estimators. Both mean squared error (MSE) and mean absolute error (MAE) are considered as performance criterion. The simulation study shows that some estimators are better than the commonly used maximum likelihood estimator and some other ridge regression estimators. Based on the simulation study and an empirical application, some useful estimators are recommended for the practitioners.

    Oil price shocks on Swedish economy: Case study on the oil's effect on a small country.2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    We estimate the macroeconomic performance in terms of inflation and GDP growth of Sweden in relations to oil price shocks, focusing on the differences across two periods, pre and post 2008. By using a Vector Error Correction model and linear hypothesis testing we can see short term and long term correlations between the nominal oil price and three dependent variables, GDP, CPI and GDP deflator. Our hypothesis is that the effects of oil price shocks are indifferent across our estimation period and this would be in line with previous literature.  We find that the macroeconomic factors of GDP and inflation responds differently post 2008 and by using impulse response functions (IRFs) we can see how the dependent variables responds to an oil price shock. They show that oil shocks have permanent effects in GDP and GDP deflator but transitory effects in CPI, we found short run causality for GDP and CPI but not for GDP deflator.

    Do environmentally sustainable practices make hotels more efficient?: A study of major hotels in Sri Lanka2019Inngår i: Tourism Management, ISSN 0261-5177, E-ISSN 1879-3193, Vol. 71, s. 213-225Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    As environmentally sustainable practices are becoming popular in the hotel industry, their impact on efficiency is an important issue. To investigate the performance of hotels in this context, we use data envelopment analysis (DEA) double bootstrap approach to firstly assess the technical efficiency and its determinants of a sample of medium and large scale hotels in Sri Lanka for the period 2010-2014. Secondly, we evaluate the impact of a number of explanatory variables in determining hotel efficiency. The results reveal that the average technical efficiency is 61% with the maximum being 71.5% and the minimum 46.8%. The results conclude that being environmentally responsible enhances the efficiency of hotels, specifically in terms of improving energy efficiency and waste management. Water consumption is shown to have a contradictory result in relation of improving efficiency. Finally, we estimate the bootstrapped Malmquist productivity index to examine the level of productivity in the Sri Lankan hotel industry. The results of this study provide hotel operators and government with insights into the nature of competitive advantage which can assist them with strategic decision making to improve the technical and environmental management of hotels.

    Propensity and motive behind the choice of Self-Employment: in rural and urban Sweden2014Independent thesis Advanced level (degree of Master (One Year)), 20 poäng / 30 hpOppgave
    Abstract [en]

    In Sweden and many other countries of the European Union throughout the entire twentieth century the self-employment has been important and essential for sustainable growth and welfare. The dynamics of self-employment have had an variance between areas that are characterized and distinguished by different labour market conditions, entrepreneurial traditions and other structural factors. In general, the agricultural importance in Swedish rural regions has declined over time, hence other small and medium industries have grown and gained more significance in these type of regions. A good example of the decline in industrialised importance for Swedish rural region is Bergslagen. Where the majority of the jobs in the traditional sectors of iron-ore mining were lost without any renewal.

    This study highlights the self-employment option out of the two-folded perspective. The first and foremost is to investigate the spatial i.e. rural-urban differences with the relation to individual motives as their choice for self-employment. Also, a second and as a side goal of the research, the propensity for self-employment is considered in order to get wider insight of the regional start-up activity in urban and rural regions. By using the rich survey dataset on ex-post motives and the register-based longitudinal data from Swedish Statistics (SCB). The regional differences in determinants for self-employment are examined by applying the binary probit and multinomial logit regressions. Additionally, in order to get a coherent unity within the multidimensional motives a factor analysis is used for grouping the motive variables into the four groups. Simultaneously for easier association to labour market the motives are also divided into typology of pull-push categories. The results regarding propensity for self-employment show small or no differences in the tendency for starting the own venture in rural side or urban regions. On the other hand, results concerning spatial aspects and motive behind the choice of occupation shows that a mutually pull and push reasons are more linked to the urban region than to the rural. Comparable results are observed on the subject of single ex-post motive “non-monetary” in respective area i.e. rural and urban.

    Labor Mobility and Local Labor Markets: Case of Sweden 2005-20112013Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The awareness of an aging population and high, stubborn unemployment in Sweden, led us into this research area. This paper presents a quantitative study, analyzing if municipal policies are effective in attracting native- and international labor migration. Further we observe if the labor mobility has any stabilizing impact on the local labor market. By using data from 2005 - 2011, the two way fixed effect regression shows that all of our three policies, social benefits, tax rate and childcare costs have significant, but modest negative effect on native location choices. When we run the same test for foreign migration, we did not find such effect at all. The same happens when we investigating if the in- and outmigration have stabilizing effect on the unemployment/vacancy ratio which measure the local labor market, we could not obtain any significance in the tests.

    The impact of minimum wages on the incentives of education for the youth2017Independent thesis Advanced level (degree of Master (One Year)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The purpose of this thesis is to investigate the incentives regarding the education decisions, resulting from a minimum wage over the period 2005-2014. The question is investigated by comparing the changes in the wage dispersion and upper secondary graduation rate in 17 OECD countries. And then, by comparing the changes in the bites of the minimum wage and educational attainment for upper secondary students in 11 OECD countries, where minimum wages are regulated by law. The majority of previous research seem to point out a negative educational effect of minimum wages. However, this paper finds no evidence that increasing the minimum wage can decrease the high school graduation rate. A possible explanation is that the correlation between the higher employment prospect and educational attainment can create incentives for young individuals to undergo education. This study seems to be the first to investigate the educational effects of minimum wages using internationally comparative data.

    How does a decrease of the number of hours worked per week impact productivity and consequently employment?2016Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    This paper aims to study the effect of the 35 hours week in France on productivity and employment.  France has  implemented  3  successive laws  to  promote  the 35  hours  week through financial incentives in order to improve work sharing.  None of the previous studies agree on the possible impact of such a policy. In this paper, we conduct a Granger Causality test in order to analyse the consequences of the decrease of working hours on productivity and then  employment.  The  results  show  no  causality from  the  number  of  working  hours  to employment. Our main explanation is that the law has never been fully applied and the period was not long enough to observe an important effect of the unemployment rate.  Besides, the level of wage compensation might not have been well calibrated. As a result of our study, we suggest that introducing such a policy, such as reducing working hours to increase employment, in countries where working hours are already short (40 or less) must be well examined before implementation and different characteristics of labour market must be taken into account.

    Intergenerational transmission of education in Norway, Portugal, Spain and Sweden: How much of the parents´ education does the children inherit?2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    This essay studies the intergenerational transmission of education in four European countries, Norway, Portugal, Spain and Sweden. Ordinal variables are used to distinguish between low, middle and high education for both the respondent and the respondent´s parents. The main findings are that Portugal has the highest intergenerational transmission of education from parents to children. Spain is on a second place, Norway on a third and on a last place, Sweden. Another finding is that the respondent´s that are 50-60 years old have a significantly higher risk of being low educated and a lower chance of being highly educated in comparison to the respondent´s that are 30-40 years old. Having a highly educated parent increases the chance of being highly educated and decreases the risk of being low educated in comparison to having a low educated parent. Having a low educated parent decreases the chance of being highly educated and increases the risk of being low educated in comparison to having a highly educated parent.

    Matchningseffektiviteten för Sverige, Norrköping och Linköping: Kan beveridgekurvan förklara en del av skillnaden i arbetslöshet mellan Norrköping och Linköping och hur ser deras matchningseffektivitet ut i relation till Sveriges?2018Independent thesis Advanced level (degree of Master (One Year)), 20 poäng / 30 hpOppgave
    Abstract [sv]

    I slutet av år 2016 hade Norrköping dubbelt så hög arbetslöshet än Linköping, trots att kommunerna har många likheter och att det endast skiljer 4 mil mellan städerna. För att analysera huruvida matchningseffektiviteten skiljer sig åt mellan landet som helhet och kommunerna Norrköping och Linköping har nationella beveridgekurvor för Sverige, samt lokala beveridgekurvor för Norrköping och Linköping skapats. Minsta kvadratmetoden med fixa effekter och robusta standardfel används med näst intill alla Sveriges kommuner för att skatta den långsiktiga jämviktsrelationen mellan arbetslöshet och vakansgrad med arbetskraftens rörlighet, invandring och månatliga säsongsvariationer som kontrollvariabler.

    Beveridgekurvorna som skapats för Sverige, Norrköping och Linköping visar ett liknande mönster under merparten av åren från 1995. Matchningseffektiviteten har gått från en sämre matchning till en bättre, men efter den finansiella krisen 2009 återhämtade sig Linköping till en bättre matchning när Norrköping samt Sverige stagnerade på en hög arbetslöshet samt en hög vakansgrad. Regressionen skattar en jämviktsrelation mellan arbetslöshet och vakansgrad och visar ett negativt samband mellan de två. Ett högt utbyte av arbetskraft, genom in- och utpendling, samt invandring har en tilltagande effekt på arbetslösheten.

    Testing for unit roots in panel data using a wavelet ratio method2013Inngår i: Computational Economics, ISSN 0927-7099, E-ISSN 1572-9974, Vol. 41, nr 1, s. 59-69Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    For testing unit root in single time series, most of the tests concentrate in the time domain. Recently, Fan and Gracay (2010) proposed a wavelet ratio test which took advantage of the information from frequency domain by using wavelet spectrum decompose methodology. This test shows a better power over many time domain based unit root test including the Dickey-Fuller (1979) type of test in the univariate time series case. On the other hand, various unit root tests in multivariate time series appear since the pioneering work of Levin and Lin (1993). Among them, the Im-Pesaran-Shin (IPS) (1997) test is widely used for its straightforward implementation and robustness to heterogeneity. The IPS test is a group mean test which uses the average of the test statistics for each single series. As the test statistics in each series can be flexible, this paper will apply the wavelet ratio statistic to give a comparison with the test by using Dickey-Fuller  statistic in the single series. Simulation result shows a gain in power by employing the wavelet ratio test instead of the Dickey-Fuller  statistic in the panel data case. As the IPS test is sensitive to the cross sectional dependence, we further compare the robustness of both test statistics to the cross sectional. Finally we apply a residual based wavestrapping methodology to reduce the over biased size problem brought up by the cross correlation for both test statistics.

    Migration to the European Union: A study on the effect of social expenditure on immigration2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Migration to the European Union has increased the last ten years with asylum immigrants being a large part. There is an ongoing debate about the cost of migration and whether or not immigrants tend to cluster in countries with high social benefits. Theoretical framework in the field of migration economics show a connection between level of immigration and the welfare system.This thesis will use macro-data on migration flows, social expenditure, wages, employment and immigrant population from OECD which will be combined with micro-data of individual views on politics and welfare. This will hopefully shed light on if the level of social expenditure and individual opinion with regards to willingness to help others may affect immigration.The question for this thesis is : Does a generous welfare system or high level of government social expenditure in a certain country within the European Union attract a high inflow of immigrants?Results show, as other research conducted in similar fashion, both a positive and negative impact by social expenditure depending on the type of regression made. A conlusion about whether the effect of social expenditure is positive or negative could not be done at this point in time for this research.

    Performance of Some Ridge Parameters for Probit Regression: With Application to Swedish Job Search Data2013Inngår i: Communications in statistics. Simulation and computation, ISSN 0361-0918, E-ISSN 1532-4141, Vol. 42, nr 3, s. 698-710Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In ridge regression the estimation of the ridge parameter is an important issue. This paper generalizes some methods for estimating the ridge parameter for probit ridge regression (PRR) model based on the work of Kibria et al. (2011). The performance of these new estimators are judged by calculating the mean square error (MSE) usingMonte Carlo simulations.  In the design of the experiment we chose to vary the sample size and the number of regressors. Furthermore, we generate explanatory variables that are linear combinations of other regressors, which is a common situation in economics. In an empirical application regarding Swedish job search data we also illustrate the benefits of the new method.

    Ridge estimators for probit regression: with an application to labour market data2014Inngår i: Bulletin of Economic Research, ISSN 0307-3378, E-ISSN 1467-8586, Vol. 66, nr S1, s. S92-S103Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this paper we propose ridge regression estimators for probit models since the commonly applied maximum likelihood (ML) method is sensitive to multicollinearity. An extensive Monte Carlo study is conducted where the performance of the ML method and the probit ridge regression (PRR) is investigated when the data is collinear. In the simulation study we evaluate a number of methods of estimating the ridge parameter k that have recently been developed for use in linear regression analysis. The results from the simulation study show that there is at least one group of the estimators of k that regularly has a lower MSE than the ML method for all different situations that has been evaluated. Finally, we show the benefit of the new method using the classical Dehejia and Wahba (1999) dataset which is based on a labor market experiment.

    Birth order and child health2016Rapport (Annet vitenskapelig)
    Abstract [en]

    Previous research has established that birth order affects outcomes such as educational achievements, IQ and earnings. The mechanisms behind these effects are however still largely unknown. In this paper we examine birth order effects on health, and whether health at young age could be a transmission channel for birth order effects observed later in life. We find no support for the birth order effect having a biological origin; rather firstborns have worse health at birth. This disadvantage is reversed in early age and later-born siblings are more likely to be hospitalized for injuries and avoidable conditions, which could be related to less parental attention. In adolescence and as young adults younger siblings are more likely to bein poor mental health and to be admitted to hospital for alcohol induced health conditions. We also critically test for reverse causality by estimating fertility responses to health of existing children. We conclude that the effects on health are not severely biased, however the large negative birth order effects on infant mortality are partly due to endogenous fertility responses.

    Employer attitudes towards refugee immigrants: Findings from a Swedish survey2016Inngår i: International labour review (Print), ISSN 0020-7780, E-ISSN 1564-913X, Vol. 155, nr 2, s. 315-337Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Based on a large-scale survey of Swedish firms, the authors identify significant heterogeneity in their attitudes towards refugee hiring, job performance, wage setting and discrimination, though experience of employing refugees reduces negative attitudes. Firms' reasons for discontinuing their employment of refugees are not related to discrimination by staff or customers, but rather to refugees' suboptimal job performance. While the majority of firms do not regard the collectively agreed minimum wages as an important obstacle to the hiring of refugees, firms with a large share of refugees on the payroll report that reducing those wage rates would enhance employment substantially.

We show that most types of major conditions have long-run effects on future outcomes, and that the strongest effects result from mental conditions.

    We use the Swedish compulsory school reform to estimate the causal effect of parental education on sons' outcomes. To this end, we use data from the Swedish military enlistment register on the entire population of males and consider outcomes, such as cognitive skills, noncognitive skills, and various dimensions of health at the age of 18. We find positive effects of maternal education on sons' skills and health status but no effects of paternal education. One reason behind this result may be that the fathers affected by the reform did not face any labor market returns to their increased schooling.

    In this paper, we exploit the Swedish compulsory schooling reform in order to estimate the causal effect of parental education on son's outcomes. We use data from the Swedish enlistment register on the entire population of males and focus on outcomes such as cognitive skills, non-cognitive skills, and various dimensions of health at the age of 18. We find significant and positive effects of maternal education on sons' skills and health status. Although the reform had equally strong effects on father’s education as on mother’s education, we find little evidence that paternal education improves son’s outcomes.

    The health-schooling relationship: evidence from Swedish twins2016Inngår i: Journal of Population Economics, ISSN 0933-1433, E-ISSN 1432-1475, Vol. 29, nr 4, s. 1191-1215Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Health and education are known to be highly correlated, but the mechanisms behind the relationship are not well understood. In particular, there is sparse evidence on whether adolescent health may influence educational attainment. Using a large registry dataset of twins, including comprehensive information on health status at the age of 18 and later educational attainment, we investigate whether health predicts final education within monozygotic (identical) twin pairs. We find no evidence of this and conclude that health in adolescence may not have an influence on the level of schooling. Instead, raw correlations between adolescent health and schooling appear to be driven by genes and twin-pair-specific environmental factors.

    Body Size, Skills, and Income: Evidence From 150,000 Teenage Siblings2014Inngår i: Demography, ISSN 0070-3370, E-ISSN 1533-7790, Vol. 51, nr 5, s. 1573-1596Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We provide new evidence on the long-run labor market penalty of teenage overweight and obesity using unique and large-scale data on 150,000 male siblings from the Swedish military enlistment. Our empirical analysis provides four important results. First, we provide the first evidence of a large adult male labor market penalty for being overweight or obese as a teenager. Second, we replicate this result using data from the United States and the United Kingdom. Third, we note a strikingly strong within-family relationship between body size and cognitive skills/noncognitive skills. Fourth, a large part of the estimated body-size penalty reflects lower skill acquisition among overweight and obese teenagers. Taken together, these results reinforce the importance of policy combating early-life obesity in order to reduce healthcare expenditures as well as poverty and inequalities later in life.

    Body size, skills, and income: Evidence from 150,000 teenage siblings2013Rapport (Annet vitenskapelig)
    Abstract [en]

    Despite the widely described consequences of childhood and adolescent overweight and obesity the economics literature to date has almost exclusively focused on the relationship between body size and earnings among adults. We provide new evidence on the long-run labor market penalty of teenage overweight and obesity using unique and large-scale data on 150,000 male siblings from the Swedish military enlistment. Our empirical analysis provides four important results. First, we show for the first time that there is a large adult male labor market penalty for being overweight and obese as a teenager. Second, we show that this result can be replicated using data from the USA and the UK. Third, we show a strikingly strong within-family relationship between body size, on the one hand, and cognitive skills and non-cognitive skills, on the other hand. Fourth, we show that a large part of the estimated body size penalty reflects lower skill acquisition among overweight and obese teenagers. All of these results hint at the importance of policy combating early life obesity in order to reduce healthcare expenditures as well as poverty and inequalities later in life.

    Height and Earnings: The Role of Cognitive and Noncognitive Skills2014Inngår i: The Journal of human resources, ISSN 0022-166X, E-ISSN 1548-8004, Vol. 49, nr 1, s. 141-166Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We use large-scale register data on 450,000 Swedish males who underwent mandatory military enlistment at age 18, and a subsample of 150,000 siblings, to examine why tall people earn more. We show the importance of both cognitive and noncognitive skills, as well as family background and muscular strength for the height-earnings relationship. In addition, we show that a substantial height premium remains after these factors have been accounted for, which originates from very short people having low earnings. This is mostly explained by the sorting of short people into low-paid occupations, which may indicate discrimination by stature.

    When a Little Dirt Doesn’t Hurt: The Effect of Family Size on Child Health Outcomes2013Rapport (Annet vitenskapelig)
    Abstract [en]

    : This paper studies the causal effect of family size on children’s health. We formulate a model of child health production where family size has a negative effect on child health due to resource dilution but a positive effect due to a positive effect on the development of the immune system, as proposed by the hygiene hypothesis. We use a large dataset on the entire Swedish male birth cohorts between 1965 and 1978 to evaluate which effect that dominates. We use the occurrence of twin births as exogenous shifts in family size. Overall, our results suggest that family size has a positive effect on general health outcomes. This suggests that the mechanism proposed in the hygiene hypothesis dominates the mechanism proposed in the quantity-quality model.

    Tingsrätters effektivitet och produktivitet2017Rapport (Annet vitenskapelig)
    Abstract [sv]

    Statens reformering av tingsrätterna har inte gett förväntad effekt. Trots förändrade arbetssätt och en sammanslagning av tingsrätter från 96 till 48 når många tingsrätter inte regeringens verksamhetsmål.

    Riksrevisionens granskning av den långsiktiga tekniska effektiviteten åren 2012– 2015 visar att effektiviteten är hög men att det finns en utvecklingspotential. Den varierar dock mellan de olika tingsrätterna. Vidare visar granskningen att produktiviteten har minskat över åren för en majoritet av tingsrätterna. Det framkommer också att tingsrätternas storlek har en koppling till nivån på ineffektiviteten.

    Granskningen bygger på DEA-metoden som mäter effektiviteten genom en inbördes jämförelse av tingsrätterna.

    För att höja effektiviteten och produktiviteten hos tingsrätterna rekommenderar Riksrevisionen Domstolsverket och tingsrätterna med att påbörja ett arbete för att identifiera interna och externa faktorer som påverkar både effektivitet och produktivitet. Riksrevisionen rekommenderar även Domstolsverket att ta hänsyn till att ineffektiviteten inte är jämt fördelad om effektiviseringsarbete ska genomföras. Enligt den modell som Riskrevisionen använt bedöms ett antal tingsrätter vara effektiva varför generella metoder för effektivisering riktade på samma sätt till samtliga tingsrätter inte nödvändigtvis är lämpliga.

    Arbetsförmedlingens arbetsmarknadsutbildning: små regionala skillnader i effekter2017Rapport (Annet vitenskapelig)
    Abstract [sv]

    Arbetsförmedlingens Arbetsmarknadsutbildning (AUB) syftar till att ge arbetssökande bättre möjligheter att få ett arbete och samtidigt ge arbetsgivare bättre förutsättningar att få arbetssökande med lämplig kompetens. Riksrevisionen har granskat hur väl Arbetsförmedlingen lyckats med att skapa likvärdiga effekter i olika regioner för den arbetsmarknadspolitiska insatsen AUB.

    Granskningen visar att skillnaderna i effektstorlek mellan olika marknadsområden är relativt liten. Variationen i effekten av AUB tycks inte heller ha ökat nämnvärt efter att upphandlingen av AUB centraliserades då Arbetsförmedlingen bildades 2008.

    För hela landet visar resultaten att det är fler individer som två år efter avslutad AUB har en inkomst som överstiger ett prisbasbelopp, drygt 40 000 kronor, än för jämförbara arbetslösa som inte tagit del av AUB. För hela den studerade tidsperioden var andelen med en inkomst över ett prisbasbelopp cirka åtta procentenheter högre för deltagarna i AUB än för personerna i jämförelsegruppen.

    För att uppnå likvärdiga effekter i olika regioner rekommenderar Riksrevisionen Arbetsförmedlingen att vid effektutvärderingar av arbetsmarknadspolitiska program inkludera ett regionalt perspektiv.

    Åtgärder till varslade: en effektutvärdering av extrainsatta utbildningsinsatser till varslade vid Volvo Cars och dess underleverantörer 2008/20092015Independent thesis Advanced level (degree of Master (One Year)), 20 poäng / 30 hpOppgave
    Abstract [sv]

    Vilka effekter ger särskilda insatser till personer som är uppsagda till följd av varsel? Denna uppsats syftar till att undersöka effekterna på återgång till arbete av extra-insatta utbildningar som syftade till omställning vilka fanns tillgängliga för de som varslades vid Volvo Cars och dess underleverantörer 2008/2009. Effektutvärderingen utgår ifrån överlevnadsanalys där projektgruppen matchas mot en kontrollgrupp bestående av samtliga övriga varslade i Sverige. Resultaten visar att gruppen som tog del av utbildningsinsatserna hade signifikant långsammare återgång till arbete jämfört med en matchad kontrollgrupp.

    Income convergence between natives and immigrants at different education levels in Sweden2018Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Drawing on the European Social Survey the main objective of this essay is to assess whether there are differences in income convergence between immigrants and natives depending on whether one has a university education or not. This approach contrasts that of most other studies on income assimilation, as they typically only use education as a control variable. The results indicate that immigrants with lower education experience a larger negative income gap at arrival, but that their convergence rates are faster than those with higher education. Furthermore, the results imply that studying income convergence is very sensitive to having the proper kind of data. Using cross-sectional data, the study appears to suffer from various sources of bias.

    Selection into self-employment: gender differences in Chile2019Independent thesis Advanced level (degree of Master (One Year)), 20 poäng / 30 hpOppgave
    Abstract [en]

    This study examines gender differences in the choice to become self-employed in Chile,focusing especially on the influence of the predicted earnings differential between selfemploymentand wage-employment. By estimating selectivity adjusted incomeequations, earnings in both sectors are predicted for each individual and the difference isused as an explanatory variable in a probit model where the dependent variable measuresself-employment status. The results show that men respond positively to the earningsdifferential whereas women respond negatively, indicating that the female choice ismostly influenced by push factors. It is also found that having small children has animportant effect on women in particular. Lastly, a comparison between employers andown-account workers shows that employers are more uniform across genders than ownaccountworkers. Due to a possibly inadequate identification strategy, these results shouldhowever be viewed with caution.

    How does mid-age individual’s investment in tertiary education affect the probability to remain in the labor market after 65?2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    This essay examines whether an investment in tertiary education in mid-age increase the probability to remain in the labor market after age 65 in Sweden. In addition, we analyze whether there is any difference in the probability to continue work after 65 if individuals choose to invest in tertiary education in mid-age or in any other age. This study utilizes already existing data that is a combination of a questionnaire survey and Swedish register data. In the sample there are 5235 individuals who are retired and 881 who are still in the labor market, born between 1938 and 1949. The implemented method is a linear probability model to obtain mean marginal effect. The results indicate that individuals who invested in tertiary education in mid-age have a higher probability to remain in the labor market after 65 than individuals with no tertiary education. There is, however, no statistically significant difference in probability depending on when they decide to invest in tertiary education.

    Robust critical values for unit root tests for series with conditional heteroscedasticity errors: an application of the simple NoVaS transformation2017Inngår i: Cogent Economics & Finance, E-ISSN 2332-2039, Vol. 5, nr 1, s. 23artikkel-id 1274282Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this paper, we introduce a set of critical values for unit root tests that are robust in the presence of conditional heteroscedasticity errors using the normalizing and variance-stabilizing transformation (NoVaS) in Politis (2007) and examine their properties using Monte Carlo methods. In terms of the size of the test, our analysis reveals that unit root tests with NoVaS-modified critical values have actual sizes close to the nominal size. For the power of the test, we find that unit root tests with NoVaS-modified critical values either have the same power as, or slightly better than, tests using conventional Dickey–Fuller critical values across the sample range considered.
