    Tony Atkinson and his Legacy2017Ingår i: The Review of Income and Wealth, ISSN 0034-6586, E-ISSN 1475-4991, Vol. 63, nr 3, s. 411-444Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Tony Atkinson is universally celebrated for his outstanding contributions to the measurement and analysis of inequality, but he never saw the study of inequality as a separate branch of economics. He was an economist in the classical sense, rejecting any sub-field labelling of his interests and expertise, and he made contributions right across economics. His death on 1 January 2017 deprived the world of both an intellectual giant and a deeply committed public servant in the broadest sense of the term. This collective tribute highlights the range, depth and importance of Tony's enormous legacy, the product of almost fifty years’ work.

    Does openness affect economic growth?: A panel data on developing and developed countries2018Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This paper investigates the impact of trade openness on economic growth through a panel analysis containing a set of 61 countries over 15 years. The method we use is the fixed effect regression model in Stata, to see whether openness to trade has explanatory power over GDP per capita growth. We use secondary data taken from World bank and Worldwide Governance Indicators. The data used is a panel data containing 61 countries and the period we are studying starts at 2002 and ends in 2016, a 15 years' time interval. Our empirical results suggest that openness during these years have had a small negative impact on growth, but although this, the variable does not seem to have a statistical significance upon per capita growth within this period of time. Therefore, with reference to this study we cannot see any significance of openness upon growth.

    Incentives and Inequalities in Family and Working Life2018Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    Essay I: Same-gender teachers may affect educational preferences by acting as role models for their students. I study the importance of the gender composition of teachers in math and science during lower secondary school on the likelihood to continue in math-intensive tracks in the next levels of education. I use population wide register data from Sweden and control for family fixed effects to account for sorting into schools. According to my results, the gender gap in graduating with a math-intensive track in upper secondary school would decrease by 16 percent if the share of female math and science teachers would be changed from none to all at lower secondary school. The gap in math-related university degrees would decrease by 22 percent from the same treatment. The performance is not affected by the higher share of female science teachers, only the likelihood to choose science, suggesting that the effects arise because female teachers serve as role models for female students.

    The (in)effectiveness of financial incentive on fertility behaviour: Childcare –a safety net for children?2017Licentiatavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    Is childcare a safety net for vulnerable children? This paper investigates the role of childcare for the health outcomes of children whose parents are unemployed. Exploiting time variation in childcare access resulting from a reform requiring Swedish municipalities to provide childcare also for children with unemployed parents, we estimate causal effects on health, as measured by register data on hospitalizations. We find that access to childcare reduced hospitalizations for infections among toddlers, especially among boys. Among children in preschool age access to childcare caused a temporary increase in hospitalization for infections the year they got access to childcare.

    Childcare - A safety net for children? 2018Rapport (Övrigt vetenskapligt)
    Abstract [en]

    We analyze how access to childcare affects health outcomes of children with unemployed parents using a reform that increased childcare access in some Swedish municipalities. For 4–5 year olds, we find an immediate increase in infection-related hospitalization, when these children first get access to childcare. We find no effect on younger children. When children are 10–11 years of age, children who did not have access to childcare when parents were unemployed are more likely to take medication for respiratory conditions. Taken together, our results thus suggest that access to childcare exposes children to risks for infections, but that need for medication in school age is lower for children who had access.

    Does fuel price affect trucking industry’s network characteristics?: evidence from Denmark2014Rapport (Övrigt vetenskapligt)
    Abstract [en]

     The 2000s were dominated by rising fuel prices and economic recession. Both had an impact on the structure of the trucking industry and how freight was moved. This paper examines how fuel prices shaped trucking industry’s network characteristics such as the average length of haul, average load, and capacity utilization. In particular, we show the effect of fuel price on average length of haul using 29 quarterly independent surveys from the Danish heavy goods vehicle (HGV) trip diary from 2004 to 2011. The results show that the average length of haul is sensitive to changes in fuel price: a DKK 1 (0.18$) increase in diesel price/liter leads to a 4 percent decrease in the average length of haul in the 2004-2007 period. This implies that firms improve transport efficiency by reducing the number of kilometers needed to transport a tonne of cargo as a short run response to fuel price increases. This result, however, is not confirmed for the years following the 2008 financial crisis. It also depends on where in the distribution of the average length of haul one looks.

    Economic effects of air transport market liberalization in Africa2016Ingår i: Transportation Research Part A: Policy and Practice, ISSN 0965-8564, E-ISSN 1879-2375, Vol. 92, s. 326-337Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Although the aviation industry is increasingly becoming important for Africa's economic development and integration, the ability of airlines to access foreign markets remains hindered by restrictive regulatory policies. Attempts have been made to fully liberalize the intra-African air transport market. Except for general assertions about the merits/demerits of liberalization, our empirical understanding of the welfare effects of such polices in Africa remains rudimentary. This study empirically measures the economic effects of air transport liberalization, mainly on two supply side variables: fare and service quality, measured as departure frequency. The empirical models evaluate how air fares and departure frequency respond to measures of openness in air services agreements, while controlling for other determinants. The results show up to 40% increase in departure frequency in routes that experienced some type of liberalization compared to those governed by restrictive bilateral air service agreements. Furthermore, there is a relatively larger increase in departure frequency in routes which experienced partial liberalization compared to fully liberalized ones. This can be explained by the diminishing marginal effect of progressive liberalization on departure frequency. While the effect of liberalization is substantial in improving service quality, there is no evidence of its fare reducing effect.

    The European Union’s Technological and Economic Development: A Study on Production of Renewable Energy2018Självständigt arbete på avancerad nivå (masterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This thesis answer the two main questions, firstly, the role of technological development in the production of RE with special reference to investment subsidy in supporting schemes and research and development (R&D). Investment subsidies in supporting schemes and R&D are widely used to promote RE technology and considered economical, efficient instruments than regulation approach. Secondly, the study investigates the relationship between the production of RE and the economic development. Panel data for twelve European Union (EU) countries are analysed for the period 1990 to 2013. The study uses a Cobb Douglas production function to estimate the EU's rational behaviour of investment subsidy between supporting schemes and R&D. For the estimation techniques, the study uses the unit root test, cointegration test, and dynamic pooling average group (PMG) model. The selection of the PMG model is based on the results of diagnostic tests, i.e. cross-sectional dependence, heteroskedasticity, serial correlation, and Hausman. Furthermore, the cointegration test confirms that in the long-run all the variables move together to achieve equilibrium. The PMG model confirms the effect of the independent variables on the dependent variable. Thus, it is concluded that the investment subsidies in supporting schemes have a positive and significant effect on the production of renewable energy in the long-run. However, the investment subsidy in research and development also has a positive but insignificant effect on the production of renewable energy in the long-run. Based on the long-run result, thus the study suggests that it is more rational to invest subsidy in supporting schemes than in R&D. In order to find the relationship between the production of RE and economic development, the result of the study confirms that economic development has a positive and significant impact on the production of renewable energy both in the short-and long-run. In addition, the test of the causality confirms the bidirectional relationship between production of RE and economic development. The bidirectional relationship states that both energy and economic growth are associated and complement each other.

    Does equity volatility affect the corporate investment level?2007Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats
    Abstract [en]

    The paper studies the relation between valuation and corporate investment level. It provides an insight to the q-model and its implications for investment level. By acknowledge the q-model’s empirical shortcomings it questions whether adjustments for volatility will strengthen the q-model empirically. It argues: as volatility is a proxy for risk, stock market volatility would be related to firm behaviour and investment decisions.

    Enhanced Oil Recovery (EOR) as a Stepping Stone to Carbon Capture and Sequestration (CCS)2018Ingår i: Mineral Economics, ISSN 2191-2203, E-ISSN 2191-2211, Vol. 31, nr 1-2, s. 239-251Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Environmental concerns about carbon emissions coupled with the oil industry’s need to secure additional CO2 for enhanced oil recovery (CO2-EOR) projects have sparked interest in the potential that CO2-EOR may have in jumpstarting carbon capture and sequestration (CCS). However, existing studies on the viability of coupling CO2-EOR with CCS have generally placed more focus on either the engineering or economic aspects of the problem. Most engineering studies focus on the technical aspects of the CO2-EOR project to produce the maximum amount of oil, while simultaneously storing the most CO2 during the production process with the economics as an afterthought, while most economic studies found have focused on a singular aspect of the issue such as impacts of exogenously varying injection rates. Furthermore, modelling efforts have stopped at the end of the productive life of the field. We build a unique two-stage dynamic optimization model, which simultaneously addresses engineering and economic policy aspects, to study the viability of coupling CO2-EOR transitioning into CCS. Our model includes a carbon tax for emissions, which becomes a subsidy for full scale sequestration after oil production has ceased; this allows us to explore the transition from CO2-EOR, our first stage, to sole CO2 sequestration in our second stage for a single field. We maximize the operator’s profits across both stages, while tracking the responsiveness of oil production and total carbon movements to both price and policy changes. We pair our optimization model with a reservoir simulation model, allowing us to mimic actual field behavior, giving our work a more realistic representation of both production and sequestration profiles. Our results suggest that small increases in the level of carbon tax can have large and discontinuous impacts on net sequestration. This stems from the observed transition from limited natural sources of CO2 to more expensive captured CO2 resulting from the implemented policy. With appropriate taxes, total volumes of captured CO2 sequestered across both stages are equivalent to 30 to 40% of the emissions from the use of the oil produced. With the credits oil producers receive from sequestering CO2, which equate to the tax, relatively high carbon taxes incentivize additional sequestration without significantly impacting the supply of oil. This, alongside maintaining a steady stream of profits, is a win-win situation for energy security and the climate.

    Does Export Diversification Boosts Economic Growth in Sub SaharanAfrica Countries?2017Självständigt arbete på avancerad nivå (magisterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Growth induced export has become a major concern for policy makers to transform and upgrade the export composition to achieve economic growth objectives; in this respect, export diversification become at the heart of growth induced export narrative. Nevertheless, this study attempts to find relationship between export diversification and economic growth. To investigate this relationship, a cross-section method is used with averaged data from the period 1991 to 2009 of 41 sub Saharan Africa countries; moreover, diagnostic tests were conducted to ensure the robustness of the model. The empirical result of this study shows positive correlation between export diversification and economic growth which can be concluded that export diversification promotes economic growth.

    A Study on the Low Volatility Anomaly in the Swedish Stock Exchange Market: Modern Portfolio Theory2017Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This study investigates, with a critical approach, if portfolios consisting of high beta stocks yields more than portfolios consisting of low beta stocks in the Swedish stock exchange market. The chosen period is 1999-2016, covering both the DotCom Bubble and the financial crisis of 2008. We also investigate if the Capital Asset Pricing Model is valid by doing a test similar to Fama and Macbeth’s of 1973.

    Based on earlier studies in the field and our own study we come to the conclusion that high beta stocks does not outperform low beta stocks in the Swedish stock market 1999-2016. We believe that this relationship arises from inefficiencies in the market and irrational investing. By doing this study we observe that, the use of beta as the only risk factor for explaining expected returns on stocks or portfolios is not correct.

    Supply chain process maturity and financial performance study of Swedish steel SMEs2010Ingår i: Proceedings of  the 17th Euroma conference, 2010Konferensbidrag (Refereegranskat)
    Abstract [en]

    The goal of this research is to demonstrate that the financial performance of the current year in Swedish steel SMEs is dependent on the amount of maturity of supply chain processes. This is examined by considering current supply chain process maturities of the firm together with financial performance of prior years. It was found that the delivery process of supply chain processes and prior cost of goods sold (COGS) have an effect on current COGS. Additionally, prior inventory and plan process of the supply chain have a positive and negative effect on inventory turnover respectively.

    The Main Support Mechanisms to Finance Renewable Energy Development2014Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Considering that the major part of greenhouse gases is carbon dioxide, there is a global concern aimed at reducing carbon emissions. Additionally, major consumer countries are looking for alternative sources of energy to avoid the impact of higher fossil fuel prices and political instability in the major energy supplying countries. In this regard, different policies could be applied to reduce carbon emissions, such as enhancing renewable energy deployment and encouraging technological innovation and creation of green jobs. There are three main support mechanisms employed by governments to finance renewable energy development programs: feed-in-tariffs, tax incentives, and tradable green certificates. Considering that many of the promising technologies to deploy renewable energy require investment in small-scale energy production systems, these mechanisms could be used to enhance renewable energy development at the desired scale. Employing a carbon emission tax or emission trading mechanism could be considered ideal policies to mitigate emissions at the lowest cost. The comparison of feed-in-tariffs and renewable portfolio standard policies showed that the former is good when a policy to develop renewable energy sources with a low level of risk for investors is considered. However, the latter is an appropriate policy when a marketview policy is applied by the government.

    Energy security and competition over energy resources in Iran and Caucasus region2017Ingår i: AIMS Energy, ISSN 2333-8326, E-ISSN 2333-8334, Vol. 5, nr 2, s. 224-238Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Energy security as a dominant factor in international stability is of great importance for major economies. The global energy market with its current level of supply and demand relies on energy sources in the Middle East, Caucasus, Central Asia and Russia. After the Fukushima disaster nuclear powers in Europe view renewable energy sources as a serious alternative. Europe’s energy vulnerability has deteriorated due to the Russia-Ukraine conflict. However, renewable energy sources are not large enough to replace nuclear power completely. This trend will continue with climbing demand especially in the natural gas sector as clean energy. In this research, Caucasus and Iran are considered the main sources and routes for energy transmission to the global market, including Europe. Caucasus plays a key role in bridging Europe and Asia. Also, Iran is an alternative for energy transmission to Europe after lifted sanctions. As part of the European active supply diversification policy Iran has capacity to reduce Europe’s energy dependency on Russia. However, changes in US new administration America First Policy is harmful for the EUs energy security. Caucasus aims to catch a large share of the European energy market since the Baku-Tbilisi-Ceyhan pipeline has started operations and Iran is also trying to expand its market to become a sustainable source of energy for major consumers. Therefore, Iran and Caucasus are considered reliable energy suppliers for Europe. In this regard, we analyze the best motivation for changing the direction new suppliers’ energy policies towards Europe and suggest alternative solutions to compete with rival countries in order to enhance energy security.

    The Relationship between Swedish Equity Funds´Management Fees and Performance2007Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats
    Abstract [en]

    An increasing number of people in Sweden and in the rest of the world are becoming more interested in the mutual fund sector. Investments in mutual funds have grown rapidly these past few years. Nilsson (2004) wrote that 85 percent of the Swedish population invested in mutual funds in 2004. The Swedish Investment Fund Association also found an increase in investments in mutual funds; 83 billion Swedish crowns were invested in mutual funds in 2005, an increase from 56 billion in 2004.

    The purpose of this thesis is to evaluate whether or not there is a relationship between low fee, middle fee, and high fee charging Swedish Equity funds and their respective performance (unadjusted and risk-adjusted returns). The Modigliani & Modigliani (1997) risk-adjusted performance measurement was used to calculate the risk-adjusted performance of the 130 mutual funds. And the linear regression was used to analyze whether or not there was a relationship between the variables (management fee vs. returns/risk-adjusted returns). The mutual funds were also divided into three different categories, based on their management fees; low, middle and high fee mutual funds.

    The analysis illustrated that there was no clear relationship between the management fee and the returns/risk-adjusted returns. There was some connection found between the management fee and the low, middle fee category. However, this research confirms that investors should not believe that a mutual fund which charges higher fees necessarily generate higher returns.

    Ekonomisk ojämlikhet och tillväxt i en global värld2014Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Frågan om ekonomisk ojämlikhet tillhör kanske en av de mest kontroversiella frågorna genom historien. Åsikterna om fördelar och nackdelar med ekonomisk ojämlikhet, men kanske framförallt graden av ojämlikhet går isär. Det har till en början inom forskningen antagits att ekonomisk ojämlikhet är en förutsättning för tillväxt genom att det frambringar investeringar och är viktigt för incitamentsskapandet. Ny forskning tyder däremot på att tillväxt och ekonomisk ojämlikhet har ett negativt samband, särskilt när förhållandet studeras på lång sikt. Om så är fallet har detta stor betydelse för ekonomiska och politiska beslut. Dessutom anses det att en hög grad av ekonomisk ojämlikhet hindrar ett politiskt och ekonomisk inkluderande samhälle vilket kan slå tillbaka på tillväxttakten. Denna uppsats, med avstamp i en mixad metod, undersöker förhållandet mellan ekonomisk ojämlikhet och tillväxt.

    External Linkages and Economic Growth in Colombia: Insights from a Bayesian VAR Model2010Ingår i: The World Economy, ISSN 0378-5920, E-ISSN 1467-9701, Vol. 33, nr 12, s. 1788-1810Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper investigates the sensitivity of Colombian GDP growth to the surrounding macroeconomic environment. We estimate a Bayesian VAR model with informative steady-state priors for the Colombian economy using quarterly data from 1995 to 2007. A variance decomposition shows that world GDP growth and government spending are the most important factors, explaining roughly 17 and 16 per cent of the variance in Colombian GDP growth respectively. The model, which is shown to forecast well out-of-sample, can also be used to analyse alternative scenarios. Generating both endogenous and conditional forecasts, we show that the impact on Colombian GDP growth of a substantial downturn in world GDP growth would be non-negligible but that the decline still would be mild by historical standards.

    Periods of converging carbon dioxide emissions from oil combustion in a pre-Kyoto context2016Ingår i: Environmental Development, ISSN 2211-4645, Vol. 19, s. 1-9Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper examines convergence of carbon dioxide (CO2) emissions caused by oil combustion for a panel of 86 countries considering the importance of analyzing sub-periods separately. The investigation also points at the necessity of choosing a restricted global sample, which takes into account, for instance, that Eastern Bloc countries reacted differently to increasing world crude oil prices than the rest of the world. The analysis builds on examining the β-convergence hypothesis in a neoclassical growth model setting with additional control variables such as emissions from combustion of solid fuels. The results reveal evidence in support of unconditional β-convergence of CO2 emissions intensity due to oil combustion in the restricted sample for the sub-periods 1973–1979 and 1979–1991, while no evidence for convergence was found for the post-1991, pre-Kyoto period. We could not find support for coal substituting technologies.

    Convergence of per capita carbon dioxide emissions: implications and meta-analysis2018Ingår i: Climate Policy, ISSN 1469-3062, E-ISSN 1752-7457, Vol. 18, nr 4, s. 512-525Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    There is a rich empirical literature testing whether per capita carbon dioxide emissions tend to converge over time and across countries. This article provides a meta-analysis of the results from this research, and discusses how carbon emissions convergence may be understood in, for instance, the presence of international knowledge spillovers and policy convergence. The results display evidence of either divergence or persistent gaps at the global level, but convergence of per capita carbon dioxide emissions between richer industrialized countries. However, the results appear sensitive to the choice of data sample and choice of convergence concept, e.g. stochastic convergence versus β-convergence. Moreover, peer-reviewed studies have a higher likelihood of reporting convergence in carbon dioxide emissions compared to non-refereed work. POLICY RELEVANCE The empirical basis for an egalitarian rule of equal emissions per capita in the design of global climate agreements is not solid; this supports the need to move beyond single allocation rules, and increase knowledge about the impacts of combined scenarios. However, even in the context of the 2015 Paris Agreement with its emphasis on voluntary contributions and ‘national circumstances’, different equity-based principles could serve as useful points of reference for how the remaining carbon budget should be allocated

    The Environment and Directed Technical Change2010Rapport (Övrigt vetenskapligt)
    Abstract [en]

    This paper introduces endogenous and directed technical change in a growth model with environmental constraints. A unique final good is produced by combining inputs from two sectors. One of these sectors uses “dirty” machines and thus creates environmental degradation. Research can be directed to improving the technology of machines in either sector. We characterize dynamic tax policies that achieve sustainable growth or maximize intertemporal welfare. We show that: (i) in the case where the inputs are sufficiently substitutable, sustainable long-run growth can be achieved with temporary taxation of dirty innovation and production; (ii) optimal policy involves both “carbon taxes” and research subsidies, so that excessive use of carbon taxes is avoided; (iii) delay in intervention is costly: the sooner and the stronger is the policy response, the shorter is the growth transition phase; (iv) the use of an exhaustible resource in dirty input production helps the switch to clean innovation under laissez-faire when the two inputs are substitutes. Under reasonable parameter values and with sufficient substitutability between inputs, it is optimal to redirect technical change towards clean technologies immediately and optimal environmental regulation need not reduce long-run growth.

    Agency Costs in the Process of Development1996Rapport (Övrigt vetenskapligt)
    Abstract [en]

    We analyze an economy where production is subject to moral hazard. The degree of the incentive (agency) costs introduced by the presence of moral hazard naturally depends on the information structure in the economy; it is cheaper to induce correct incentives in a society which posesses better ex post information. The degree of ex post information depends on the number of projects and entrepreneurs in the economy; the more projects, the better the information. This implies that at the early stages of development, the range of projects and the amount of information are limited and agency costs are high. Since the information created by a project is an externality on others, the decentralized economy is constrained inefficient; in particular, it does not 'experiment' enough. The analysis of the role of information also opens the way to an investigation of the development of financial institutions. We contrast the information aggregation role of stock markets and information production role of banks. Because the amount of available information increases with development, our model predicts the pattern of financial development observed in practice; banks first and stock markets later.

    Information Accumulation in Development1998Rapport (Övrigt vetenskapligt)
    Abstract [en]

    We propose a model in which economic relations and intritutions in advanced and less developed countries differ as these societies have access to different amounts of information. The lack of information in less developed economies makes it hard to evaluate the performance of manager, and leads to high "agency costs". Differences in the amount of information have a variety of sources. As well as factors related to the informational infrastructure, we emphasize that societies accumulate information partly because the scarcity of capital restricts the repetition of various activities. Two implications of our model are: (i) as an economy develops and generates more information, it achieves better risk-sharing at a given level of effort, but because agents are exerting more effort and the types of activities are changing, the overall level of risk-sharing may decline; (ii) with development, the share of financial intermediation carried out through market institutions should increase.

    Productivity Differences1998Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Many technologies used by the LDCs are developed in the OECD economies, and as such, are designed to make optimal use of the skills of these richer countries' workforces. Due to differences in the supply of skills, some of the tasks performed by skilled workers in the OECD economies will be carried out by unskilled workers in the LDCs. Since the technologies in these tasks are designed to be used by skilled workers, productivity in the LDCs will be low. Even when all countries have equal access to new technologies, this mismatch between skills and technology can lead to sizable differences in total factor productivity and output per worker. Our theory also suggests that productivity differences should be highest in medium-tech sectors, and that the trade regime and the degree of intellectual property right enforcement in the LDCs have an important effect on the direction of technical change and on productivity differences.

    Risk och avkastning: En portföljbaserad studie av Fama-French Trefaktorsmodell på den svenska aktiemarknaden2011Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    ”Capital Asset Pricing Model” (CAPM) beaktar den centrala marknadsrisken för att förklarasambandet mellan risk och avkastning hos tillgångar. Avkastningskravet betingas enligtmodellen en marknadsriskpremie vid investering i aktier eller andra tillgångar som erhåller risk. Senare studier (Banz 1981, Davis, Fama & French 2000) visar å andra sidan att aktiertill hörandes företag av olika storlek och värde utsätts för en annan typ av risk. Dessa forskare föreslår således att en värde- och storlekspremie bör inkluderas i en ny modell. De nya variablerna som utgår från bolagens olika karaktär beaktas för att särskilja de två karaktäristika som antas påverka förväntad avkastning, vilket den enskilda marknadsrisken ej gör.

    Syftet med studien är att kartlägga om storlek- och värdepremien har en signifikant roll i att förklara avkastning på den svenska aktiemarknaden. Ytterligare relevanta riskpremier skulle ge möjligheten att precisera förväntad avkastning på tillgångar, vilket skulle betyda att ytterligare faktorer av risk bör prissättas och tas hänsyn till. Detta skulle innebära ett bättre verktyg för aktörer på den finansiella marknaden såsom investerare och fondförvaltare vid investeringsbeslut. Riskfaktorerna testas i en statistisk analys med avkastningen från portföljer konstruerade efter olika kombinationer som förklarande variabel för att undersöka riskernas relevans.

    Studien lyckas påvisa att faktorerna förhållandevis väl förklarar avkastning, vilket kan tolkas som att de nya riskpremierna är prissatta riskfaktorer på den svenska aktiemarknaden. Det poängteras även hur värde- och tillväxtbolag exponeras för olika grader av risk och därmed hur avkastningskravet påverkas av dessa olika typer av riskexponeringar.

    The Entrepreneruship-Philanthropy Nexus: Implication for internationalization2005Rapport (Övrigt vetenskapligt)
    Abstract [en]

    This paper examines how Sweden and the United States have been impacted by philanthropicactivities, commercialization of university-based knowledge and internationalentrepreneurship. The analysis comprises a detailed case study of Swedish and U.S.universities, as well as a statistical analysis of the impact of philanthropy on economicgrowth. The results show that the United States has prompted a university system based oncompetition and variety, with an emphasis on philanthropy, promoting knowledge creation.International entrepreneurship has been an important mechanism by which this knowledge isglobalized leading to increased economic growth. Conversely, Swedish universities werecharacterized by less commercialized R&D and weak links to the commercial sector, rootedtraditionally in dependence on tax-financed and homogenous university structure. TheSwedish model has begun to change with important implications for development in smallerdomestic markets. The analysis has important implications for knowledge creation as asource of economic growth through international entrepreneurship taking advantage ofglobalization, especially for smaller countries.

    Philippe Aghion: recipient of the 2016 Global Award for Entrepreneurship Research2017Ingår i: Small Business Economics, ISSN 0921-898X, E-ISSN 1573-0913, Vol. 48, nr 1, s. 1-8Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Professor Philippe Aghion is the 2016 recipient of the Global Award for Entrepreneurship Research, consisting of 100,000 Euros and a statuette designed by the internationally renowned Swedish sculptor Carl Milles. He is one of the most influential researchers worldwide in economics in the last couple of decades. His research has advanced our understanding of the relationship between firm-level innovation, entry and exit on the one hand, and productivity and growth on the other. Aghion has thus accomplished to bridge theoretical macroeconomic growth models with a more complete and consistent microeconomic setting. He is one of the founding fathers of the pioneering and original contribution referred to as Schumpeterian growth theory. Philippe Aghion has not only contributed with more sophisticated theoretical models, but also provided empirical evidence regarding the importance of entrepreneurial endeavours for societal prosperity, thereby initiating a more nuanced policy discussion concerning the interdependencies between entrepreneurship, competition, wealth and growth.

    Valuation of Amenities in the Housing Market: A Hedonic Price Approach2015Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This paper intends to examine what fraction of house prices can be accredited to the distance between residential properties and proximity to parks, water and city centers. Although a large body of work on the subject of amenities and house prices using a hedonic model already exists, we wish to contribute with an in-depth analysis on these variables of focus. The empirical analysis uses a dataset concerning 8319 single family house purchases in the Swedish municipality of Jönköping, collected during the years 2000 to 2011. The main findings show that house prices are negatively effected as the distance increases to amenities and that by testing for land value as the dependent variable, we highlight the importance of geographical location while ignoring charac-teristics surrounding the house.

    Revenue mobilization in aid-dependent countries: current and future challengesManuskript (preprint) (Övrigt vetenskapligt)
    Abstract [en]

    The recent financial crisis and other climate related shocks pose important challenges to fiscal policies in a number of developing countries. The best way for developing countries to respond to the tax challenges are essentially to broaden tax bases, reduce rates and improve tax administration. But equally important, the focus has also to be on economic policies that accelerate growth and expand the tax base. In many developing countries, poor public service delivery, financed with existing revenue, creates dissatisfied citizens which are unwilling to pay taxes. A legitimate and responsive state one that secures the rule of law and keeps corruption under control is important for better mobilisation of tax revenue. With regard to the mix of tax instruments trade taxes will continue to reduce its significance as an important source of revenue. This suggests that indirect taxes such as VAT and direct taxes will be of significant importance in the future. Many developing countries have very narrow tax bases, with large number of exemptions, often designed to protect the interests of powerful groups. In these circumstances broadening the base can have the advantages of raising revenue, improving economic efficiency and achieving greater redistribution. Over the long-term taxation can reduce developing countries’ dependence upon aid and increase its ownership of the development agenda and become accountable to its citizens. This would also reinforce the social contract between state, citizens and the private sector which was how efficient institutions evolved in the developed world.

    Incumbency effects in government and opposition: Evidence from Germany2014Ingår i: European Journal of Political Economy, ISSN 0176-2680, E-ISSN 1873-5703, Vol. 36, s. 117-134Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Do district incumbents in an election have an advantage, and if so, do these advantages depend on which party is in government? We estimate the incumbency effect for the direct district candidates in German federal and state elections using a regression discontinuity design (RDD). When studying the heterogeneity in these effects, we find that incumbents from both large parties, the center-right CDU and the center-left SPD, have an advantage only if the SPD is in government. This effect is robust and shows even in state elections that are unrelated to federal elections.

    Inkomstskillnader och löneandel: en kritisk analys av tidigare forskning, med fokus på mätproblem och definitioner2014Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    I denna uppsats tittar vi på löneandelens och inkomstskillnadernas utveckling i Sverige sedan 1970-talet. Faktorer som förklarar ökade inkomstskillnader och minskad löneandel i Sverige ligger till grund för analysen. Fokus ligger även på de mätproblem som präglar löneandelen. Syftet med uppsatsen är att ge en översikt över den aktuella diskursen som råder kring inkomstskillnader och löneandelen i Sverige. Vi undersöker om det finns några samband mellan förklaringsfaktorerna till ökade inkomstskillnader och minskad löneandel i Sveriges utveckling och varför måtten är problematiska som forskningsämne. I vår slutsats finner vi det svårare att mäta löneandelen än inkomstfördelningen pga. definitionsproblem. Vi finner en koppling mellan den svenska inkomstfördelningen och löneandelen när det gäller ökade kapitalinkomster. Det går inte att säga hur mycket faktorerna påverkat löneandelen och inkomstfördelning eftersom det saknas tillförlitliga simuleringsmodeller.

    Essays on the Transmission of Human Capital and the Impact of Technological Change2013Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    Essay 1: If grandparents have an independent impact on their grandchildren's schooling, intergenerational correlations estimated using two generations will underestimate the true level of intergenerational persistence in education. Recent research has found such multi-generational effects, but there is still no consensus on whether these estimates are due to a direct impact of grandparents on their grandchildren, or if they arise because of measurement error or model misspecification. In this paper, I estimate the intergenerational transmission arising from direct interactions with grandparents by comparing families where the grandparent died before the birth of the grandchild with those where the grandparent lived to meet and spend time with the grandchild. I find that direct effects contribute most, if not all, of the transmission coefficient across three generations.

    Essay 2: Sibling correlations in education and income have been extensively studied in the literature, and attempts to look inside the correlation have focused on family and neighborhood effects. In this paper I estimate sibling spillovers in education—that is, the effect of an older sibling's schooling on their younger sibling's schooling. To estimate causal effects, I use a compulsory school reform in Sweden in the 1950s to instrument for the older sibling's schooling. I am unable to detect statistically significant sibling spillovers, implying that any such spillovers must be relatively small.

    Essay 3: (with Che-Yuan Liang) The implementation of a copyright protection reform in Sweden in April 2009 suddenly increased the risk of being caught and prosecuted for illegal file sharing. This paper uses the reform to investigate the effects of illegal file sharing on music and movie sales. We find that the reform decreased Internet traffic by 16 percent during the subsequent six months. It also increased music sales by 36 percent. Furthermore, it had no significant effects on movie sales. We conclude that pirated music is a strong substitute to legal music whereas the substitutability is less for movies.

    Essay 4: (with Magnus Gustavsson) This paper shows that between 1975 and 2005, Sweden exhibited a pattern of job polarization with expansions of the highest and lowest paid jobs compared to middle-wage jobs. The most popular explanation for such a pattern is the hypothesis of "task-biased technological change", where technological progress reduces the demand for routine middle-wage jobs but increases the demand for non-routine jobs located at the tails of the job-wage distribution. Our estimates, however, do not endorse this explanation for the 1970s and 1980s. Stronger evidence for task biased technological change, albeit not conclusive, is found for the 1990s and 2000s. In particular, there is both a statistically and economically significant growth of non-routine jobs and a decline of routine jobs. No link between wage changes and routine tasks, as would be expected from task-biased technological change, can however be established.

    Har illegal fildelning orsakat minskad skivförsäljning i Sverige?: En empirisk studie2007Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats
    Abstract [sv]

    I denna uppsats genomförs en empirisk analys av den svenska skivmarknaden och den nedgång i skivförsäljningen som skett under senare år. Fokus ligger på att undersöka om nedgången orsakats av illegal fildelning, eller om andra faktorer kan ligga bakom. Analysen sker genom en genomgång av relevanta aggregerade data för skivförsäljning, videoförsäljning, internetanvändande m.m. En enkel ekonometrisk analys görs också, och sammantaget visar resultaten att den växande konkurrensen från DVD-film troligen är en viktig orsak till den minskade skivförsäljningen. Inga tydliga bevis för att fildelningen haft en signifikant påverkan hittas. Brist på detaljdata gör dock att alla slutsatser måste tolkas försiktigt.

    Job Polarization and Task-Biased Technological Change: Evidence from Sweden, 1975–20052015Ingår i: Scandinavian Journal of Economics, ISSN 0347-0520, E-ISSN 1467-9442, Vol. 117, nr 3, s. 878-917Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper shows that between 1975 and 2005, Sweden exhibited a pattern of job polarization with expansions of the highest and lowest paid jobs compared to middle-wage jobs. The most popular explanation for such a pattern is the hypothesis of ‘task-biased technological change’, where technological progress reduces the demand for routine middle-wage jobs but increases the demand for non-routine jobs located at the tails of the job-wage distribution. Our estimates, however, do not support this explanation for the 1970s and 1980s. Stronger evidence for task biased technological change, albeit not conclusive, is found for the 1990s and 2000s. In particular, there is both a statistically and economically significant growth of non-routine jobs and a decline of routine jobs. Results for wages are, however, mixed; while task-biased technological change cannot explain changes in between-occupation wage differentials, it does have considerable explanatory power for changes in within-occupation wage differentials.

    Job Polarization and Task-Biased Technological Change: Sweden, 1975–20052011Rapport (Övrigt vetenskapligt)
    Abstract [en]

    This paper investigates the connection between the Swedish wage profile of net job creation and Autor, Levy, and Murnane’s (2003) proposed substitutability between routine tasks and technology. We first show that between 1975 and 2005, Sweden exhibited a pattern of job polarization with expansions of the highest and lowest paid jobs compared to middle-wage jobs. We then use cross-sectional and longitudinal analyses of job-specific employment to map out the importance of routine versus nonroutine tasks for these changes. Results are consistent with substitutability between routine tasks and technology as an important explanation for the observed job polarization during the 1990s and 2000s, but not during the 1970s and 1980s. In particular, the overrepresentation of routine tasks in middle-wage jobs can potentially explain 44 percent of the growth of low-wage jobs relative to middle-wage jobs after 1990 but largely lacks explanatory power in earlier years.

    Piracy and Music Sales: The Effects of An Anti-Piracy Law2014Ingår i: Journal of Economic Behavior and Organization, ISSN 0167-2681, E-ISSN 1879-1751, Vol. 105, s. 90-106Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The implementation of a copyright protection reform in Sweden in April 2009 suddenly increased the risk of being caught and punished for illegal file sharing. This paper investigates the impact of the reform on illegal file sharing and music sales using a difference-in-differences approach with Norway and Finland as control groups. We find that the reform decreased Internet traffic by 16% and increased music sales by 36% during the first six months. Pirated music therefore seems to be a strong substitute to legal music. However, the reform effects disappeared almost completely after six months, likely because of the weak enforcement of the law.
