    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.

    A search for an unexpected asymmetry in the production of e(+)mu(-) and e(-)mu(+) pairs in proton-proton collisions recorded by the ATLAS detector at root s=13 TeV2022Ingår i: Physics Letters B, ISSN 0370-2693, E-ISSN 1873-2445, Vol. 830, artikel-id 137106Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This search, a type not previously performed at ATLAS, uses a comparison of the production cross sections for e(+)mu(-) and e(-)mu(+) pairs to constrain physics processes beyond the Standard Model. It uses 139 fb(-1) of proton-proton collision data recorded at root s = 13 TeV at the LHC. Targeting sources of new physics which prefer final states containing e(+)mu(-) and e(-)mu(+), the search contains two broad signal regions which are used to provide model-independent constraints on the ratio of cross sections at the 2% level. The search also has two special selections targeting supersymmetric models and leptoquark signatures. Observations using one of these selections are able to exclude, at 95% confidence level, singly produced smuons with masses up to 640 GeV in a model in which the only other light sparticle is a neutralino when the R-parity-violating coupling lambda(23)(1)' is close to unity. Observations using the other selection exclude scalar leptoquarks with masses below 1880 GeV when g(1R)(eu) = g(1R)(mu c) = 1, at 95% confidence level. The limit on the coupling reduces to g(1R)(eu) = g(1R)(mu c) = 0.46 for a mass of 1420 GeV.

    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.

    Requirements to metrics of greenhouse gas emissions, given a cap on temperature2017Ingår i: Ecological Economics, ISSN 0921-8009, E-ISSN 1873-6106, Vol. 131, s. 460-467Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The literature on metrics to measure contributions to climate change from emissions of different greenhouse gases divides into studies that highlight physical aspects and studies that show the importance of economic factors. This paper distinguishes the physical aspects and implications of economic factors by asking what is demanded from physically based metrics if used for a specific policy objective. We study the aim of maximizing the welfare of emissions generated by consumption when there is a limit to the increase in global mean temperature. In that case, metrics ought to change over time, with increasing weight on short-living gases before the temperature limit is met. Metrics for short-living gases increase also with increasing uncertainty. Adjustments to new information spur higher metrics for short-living gases if it reduces the expected allowable emissions before the target is met, and lower metrics in the opposite case. Under a binding target, metrics refer to the instantaneous impact on radiative forcing multiplied by the lifetime of the respective gases, and adjusted by the attitude to risk.

    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.

    From Epidemic to Pandemic: Did the COVID-19 Outbreak Affect High School Program Choices in Sweden?2021Rapport (Övrigt vetenskapligt)
    Abstract [en]

    We study whether the onset of the COVID-19 crisis affected the program choices of highschool applicants in Sweden. Our analysis exploits the fact that the admission processconsists of two stages: a preliminary round in which applicants rank programs in orderof preference and a final round in which they have full flexibility to alter their preliminaryrankings. In 2020, the timing of the two rounds happened to provide a unique pre- and post-crisis snapshot of applicants’ preferences for various fields of study. Using school-leveldata on applicants’ top-ranked programs for all admission rounds between 2016 and 2020,we implement a difference-in-differences method to identify the immediate effect of thecrisis on program preferences. We find no change in preferences for academic programs,but a decline in top-ranked applications to some of the vocational programs. The declinesare most pronounced and robust for several service-oriented programs, in particular thoserelated to hotel and restaurant, which was the most adversely affected industry during thecrisis. This finding suggests that labor market considerations influence the study choicesmade by relatively young students.

    The Influence of Inflation Targeting on Economic Growth: A Critical Analysis on Developed Countries2024Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Assessing the effectiveness of inflation targeting in promoting economic growth is crucial for policymakers in determining appropriate monetary policy measures. Given the lack of consensus regarding the impact of inflation targeting on economic growth, it prompts the question of whether inflation targeting indeed exerts a significant effect on economic growth.  This bachelor's thesis investigates the impact of inflation targeting on economic growth in developed countries over a 29-year period from 1991 to 2019. Using a methodology that accounts for both static and dynamic economic growth relationships, we analyze data from 45 developed countries, some employing inflation targeting and others not. Our findings suggest a positive effect of inflation targeting on economic growth in the static model, but autocorrelation issues necessitate the use of a dynamic model. The utilization of two distinct types of dummy variables yielded disparate outcomes compared to those obtained from the static model. Results from dynamic modeling indicate a slight negative effect of inflation targeting on economic growth. Together these results point to an inconclusive effect of inflation targeting on economic growth.

    Business incubator management and entrepreneur collaboration with R&D milieus: Does the regional context matter?2022Ingår i: International Journal of Entrepreneurship and Innovation, ISSN 1465-7503, E-ISSN 2043-6882, Vol. 23, nr 1, s. 28-38Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We study whether business incubator management collaboration with R&D milieus affects incubated entrepreneurs to also collaborate with R&D milieus in different regional contexts. Empirically, we analyse 281 Norwegian entrepreneurs in 32 different business incubators. Incubator collaboration with R&D milieus increases entrepreneur collaboration with R&D milieus in sparsely but not densely populated regions. Also, education level increases collaboration with R&D milieus (plus investor milieus and international customers). Entrepreneur collaboration with R&D milieus is positively associated with market orientation and perceptual performance but tends to delay enterprise development.

    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.

    Migration and average wages in Sweden: Immigration as a labour supply shock on the Swedish labour market from the year 2011 to 2018 across municipalities2020Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    With the recent influx of foreign-born individuals migrating to Sweden, this study aims to answer the question, “do high skilled foreign-born individuals relate positively to average wages in Sweden?”. We specifically observe high skilled foreign-born individuals and their contribution to the average wage across different municipalities in Sweden between the years 2011 and 2018. The method carried out in this study consisted of an empirical analysis where the significance of economic factors was interpreted in order to understand the variation in wages. The data was extracted from Statistics Sweden. The relationship of the share of highly educated foreign-born individuals has proved to be insignificant with respect to average wages in Sweden. Different theories are discussed in this paper in order to identify the key labour market outcomes due to the labour supply shock. Our findings disclose that differences in wages are present, meaning that natives and foreign-born individuals are complements in the short run

    The SEK daily volatility and its impact on the Swedish stock market2021Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The aim of this study is to investigate the Swedish currency (SEK) exchange rate daily volatility effects on the OMX stock price volatility in two separate periods of currency depreciation and appreciation. We used the exchange rate of the four main currencies against the SEK, the USD, EUR, CYN and JPY, as a base to calculate the average daily movement and the volatility of the SEK for the period between February 2018 to December 2020. We used a modified GARCH model specially designed to address the questions of this paper following the same steps used by Fang (2002) to design his model. This paper provides evidence that the daily exchange rate volatility has a significant, but neglectable, effect on the daily stock market volatility. The results can be explained by the high level of economic stability in Sweden and the low level of uncertainty between the investor.

    Abstract [en]

    The COVID-19 pandemic has significantly altered employment and income distribution, impacting women and men differently. This study investigates the negative effects of COVID-19 on the labour market, focusing on the gender gap in five countries in the Middle East and North Africa (MENA) region. The study indicates whether women are more susceptible to losing their jobs, either temporarily or permanently, switching their primary occupation, and experiencing decreased working hours and income compared to men during the COVID-19 outbreak. The study utilizes a multivariate Probit model to estimate the relationship between gender and adverse labour outcomes controlling for correlations among outcomes. Data are obtained from the Combined COVID-19 MENA Monitor Household Survey, covering Egypt, Tunisia, Morocco, Jordan, and Sudan. The findings of this study offer empirical evidence of the gender gap in labour market outcomes during the pandemic. Women are more likely than men to experience negative work outcomes, such as permanent job loss and change in their main job. The increased childcare and housework responsibilities have significantly impacted women's labour market outcomes during the pandemic. However, the availability of telework has reduced the likelihood of job loss among women. The study's results contribute to a better understanding of the impact of COVID-19 on gender inequality in understudied MENA countries. Mitigation policies should focus on supporting vulnerable women who have experienced disproportionate negative effects of COVID-19.

    Cryptocurrencies and financial assets during COVID-19 pandemic: Example of cointegration analysis2021Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The purpose for thesis is to test the cointegration among cryptocurrencies, financial assets and COVID-19 Cases/Deaths to find if there is cointegration. The Johansen cointegration test is used in order to find if there is cointegration. For the whole period spans from April 2016 to April 2021, the results showed that there is existing cointegration between Bitcoin and each market index. For the pre-pandemic period spans from April 2016 to December 2019, the results showed that there is no cointegration between Bitcoin and each market index. For the pandemic period spans from January 2020 to April 2021, the results showed that there is no cointegration between Bitcoin and each market index. On the other side, there is no cointegration between Ethereum and each market index in the three time periods. The results for the pandemic period showed that there is cointegration between COVID-19 cases and each market index except IBEX35 in Spain. Moreover, there is existing cointegration between COVID-19 cases and each cryptocurrency. The results showed that there is cointegration between (COVID-19 deaths and each market index) and (COVID-19 deaths and each cryptocurrency). Finally, the cryptocurrencies and market indices provide advantages in terms of hedge against the pandemic.

    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.

    Supporting Micro-enterprise in Humanitarian Programming: Impact Evaluation of Business Grants versus Unconditional Cash Transfer2023Ingår i: Journal of African Economies, ISSN 0963-8024, E-ISSN 1464-3723, Vol. 32, nr 4, s. 415-437Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Humanitarian programming in fragile economies often use unconditional cash transfers (UCTs) to offset food insecurity. However, there is an increasing focus on using cash transfers to boost household incomes beyond the short-term through micro-enterprise start-up and growth. This paper conducts a randomised control trial to measure the impact of three different sizes of business grants against UCT in Somalia. We find that giving the same amount of money as a lump sum business grant results in higher likelihood of business ownership and income compared with UCT in the short run (3-4 months after the transfers). However, the impacts are larger and persist 3 years later only for those who received larger amount of grants. The results indicate our 'medium'-sized grant being more cost-effective. © 2022 The Author(s).

    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.

    Optimal rotation age of Populus deltoides considering economic value of timber harvesting and carbon sequestration2018Ingår i: Austrian Journal of Forest Science, ISSN 0379-5292, Vol. 135, nr 4, s. 315-342Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of this research is to determine the optimal rotation age of Populus deltoides plantations regarding to the timber and carbon sequestration values in the north of Iran. Two plantation types with a tree density of 3 by 3 m and of 3 by 4 m were considered in Choobar forest, northern Iran. Net present value (NPV) of timber and carbon were used for determining the optimal rotation age. Data on volume increment, carbon content, revenue, timber and carbon prices were collected to estimate NPV. In this study, we considered the effects of different plantation cost, land value and discount rates on the optimal rotation ages. Our results indicated, if economic value of timber is considered, optimal rotation ages were 10 and 8 years for 3 by 3 m and 3 by 4 m density, respectively. Optimal rotation ages considering carbon sequestration, in addition to timber value, increased to 14 and 11 years for the same two densities, respectively. Thus, integrating carbon sequestration value with timber economic value increased the optimal rotation ages and in turn change the optimal forest management. Sensitivity analysis indicate that optimal rotation ages increased with increasing plantation cost and decreased with increasing interest rate, while our results suggested that the optimal rotation age is not sensitive to the land value. Our results are important for land managers and carbon projects to optimize the used forest management practices.

    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 development2014Ingår i: Renewable & sustainable energy reviews, ISSN 1364-0321, E-ISSN 1879-0690, Vol. 40, s. 876-885Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Considering that the major part of greenhouse gases is carbon dioxide, there is a global concern aimed at reducing carbon emissions. In addition, 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 the creation of green jobs. This study compares 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 market view policy is applied by the government. Finally, considering technological progress and the cost reduction for power generation by renewable energy sources, we suggest that support mechanism policies should be reconsidered from the financial point of view.

    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.

    Abstract [en]

    Oil and gas are important natural resources and have propelled economic growth and increased the global competitiveness between producing nations in global trade and resulted in the associated advantages to domestic economies. This chapter examines the future of the oil and gas industry in emerging and developing countries. It discusses the exploration of oil and gas and how the environment is being impacted by the activities. The chapter looks at the role of market players along the value chain of the oil and gas sector. It then examines how the world is being transitioned to renewable energy use through an analysis of demand trends and challenges confronting the oil and gas industry. It makes the case that despite the immeasurable contributions of the oil and gas sector to the development of the global economy, there have been systemic shifts in their demand in recent times. High cost of capital requirements in oil and gas production, climate change effects and global warming, deprivations and community conflicts, and technological advancements account for these shifts in the demand trends of oil and gas.

    Abstract [en]

    The world, since the industrial revolution, has relied significantly on oil and gas (O&G) resources to fuel, especially for its industrial and transportation activities. The major consuming block for oil before 2012 was always the Organization for Economic Cooperation and Development (OECD) countries, which are more industrialised relative to countries in the non-OECD block. In most emerging and developing countries (EDCs), when O&G resources are discovered, they are often quick to extract these resources with the aim of rapidly growing the economy, reducing poverty, and gaining some political capital without a careful management plan. Despite the transition to low carbon economy being underway along with the associated increased interest in renewable energy sources globally, especially among policymakers and investors in developed countries, demand for O&G resources will continue to surge due to growing demand from EDCs such as China, India, South Africa, and Brazil.

    Abstract [en]

    The aim of this article is to identify which economic model is applied in Eritrea. The government claims to follow the market economy model(s), however, the actual practice seems to be different and casts doubts on the government's commitment to market economy. Against this background, the author has examined Eritrea's economic development model. Confirming to his doubts, the author found out that the government is applying a militarist command economy model, however, in an improperly planned, poorly coordinated and extremely mismanaged approach, with its serious negative impacts on the economic, social, cultural, diplomatic and political conditions in the country.

    Women’s education- perhaps one of the most powerful tools to reduce child mortality?: A cross-sectional study on the relationship between maternal education and childhood malaria prevention in Uganda2023Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Malaria is one of the leading causes of child mortality in the world today. Almost half a million children die from the disease every year (OWID 2022). Uganda is currently one of few countries globally where more than 90 % of the population are at risk of malaria (Target Malaria 2023). Decades of academic research has shown that maternal education plays an important role in the reduction of malaria in children. Hence, this thesis seeks to further explore this relationship in Uganda by first examining how maternal education impacts children’s bed net use and if the effect depends on the level of wealth. Secondly, the aim is to also analyze if maternal education increases malaria knowledge. The methods used for this were the multiple regression model and the linear probability model. The results showed that when mothers went from having no education to at least some secondary education, children’s bed net use increased with 14.8% on average. Although not statistically significant, the importance of maternal education was 2.64% higher on average for poor mothers when they went from no education to at least some primary education. Lastly, knowledge about malaria increased 0.98% on average when mothers went from no education to at least some primary education.

    Ethnic and Gender Differences in the Swedish Labour Market: Do Attitudes Towards Immigrants Matter?2021Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    International migration has had a steady growth over the last decades and the integration of immigrants into the labour market is a challenge for many countries. Previous literature has found that immigrants, especially non-European immigrants, are disadvantaged in the labour market, and that the size of this disadvantage differs between male and female immigrants. One potential explanation for non-European immigrants’ labour market disadvantage is discrimination, which can be expressed through negative attitudes towards immigrants. Using individual data from the European Social Survey, this paper investigates whether there is a relation between negative attitudes towards immigrants and the employment gap between non-European immigrants and natives in Sweden, and whether this relation differs by gender. The results, however not statistically significant, indicate that there is a negative relation between negative attitudes towards immigrants and the immigrant-native employment gap. Moreover, the female immigrant-native employment gap is found to be more negatively affected by negative attitudes towards immigrants.

    Economic Development and CO2 emissons: A comparison of High- and Middle-income economies2020Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The purpose of this paper is to investigate the relationship between economic development and pollution in the middle- and high-income countries for the period between 1960 and 2014. The study is conducted by first testing the environmental Kuznets curve, an economic theory that income has an inverted U-shape relationship with environmental degradation. Later, the Revised environmental Kuznets curve is tested, an economic theory that countries undergoing economic development at a later period will have a lower peak of environmental degradation compared to countries undergoing economic development at an earlier period. Empirical tests of carbon dioxide (CO2) per capita and income (GDP per capita) were conducted in two different panel tests containing middle-income countries in one and high-income countries in the other. The observed relationship shows that a country's early economic development degrades the environment until what is called the turning point is reached, after which the environment improves with further economic development. Thus, the expected inverted U-shape is observed for both MIE and HIE. Furthermore, the tests tell us that the turning point for MIE is significantly lower than for HIE, which is the expected result.

    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.

    Who moves and who gains from internal migration in Egypt?: Evidence from two waves of a labor market panel survey2022Ingår i: Habitat International, ISSN 0197-3975, E-ISSN 1873-5428, Vol. 124, artikel-id 102573Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In recent decades, Egypt has experienced rapid internal migration movements triggered by urbanization, socioeconomic development, and environmental changes. From a literature perspective, few scholarly studies have empirically examined the drivers and welfare impacts of internal migration in Egypt, despite the increasing recognition of its inextricably links to urban sustainability. The present study utilized data from two waves of an Egyptian Labor Market Panel Survey (ELMPS) conducted in 2012 and 2018 and consisting of 63,909 observations to examine factors that determine internal migration decisions and their subsequent welfare effects. The results of the two-stage Heckman selection model indicate that both the determinants of internal migration decisions and welfare outcomes differ appreciably depending on migration stream as well as the socioeconomic characteristics of the migrants. In particular, females were found to be more likely to migrate from rural to urban areas, lending support to the growing literature on the “feminization of migration” in developing countries. The OLS regression results, after correcting for self-selection, make a strong case for the positive welfare gains from internal migration in Egypt. Specially, we found that the welfare gains for older and female migrants are much higher than other age and gender groups. A comparison of the welfare effects between different migration streams shows that all migratory movements were associated with positive and statistically significant welfare gains, except for rural-to-urban migration that was surprisingly found to be associated with significant welfare loss for the migrants. Urban-to-urban migration was found to have the strongest welfare enhancing effects on all migrant groups. The empirical findings underline a number of research and policy implications for a sustainable management of internal migration in Egypt and other countries with similar internal migration trends.

    In the midst of the COVID-19 pandemic: Perceived risks, management strategies and emerging opportunities for small and medium agri-food enterprises in a developing country2023Ingår i: International Journal of Disaster Risk Reduction, E-ISSN 2212-4209, artikel-id 104045Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Covid-19 pandemic has posed unprecedented challenges to small and medium agri-food enterprises (SMAEs) in developing countries. However, research investigating what risks Covid-19 posed to these firms, how they responded, and what business opportunities emerged to SMAEs from the pandemic remains scanty. Drawing on a sample of 166 specialist SMAEs in Egypt, this study addressed these entwined questions by using multiple indicators and multiple causes (MIMIC) and mediation analysis. Our results point out that the Covid-19 pandemic exposed Egyptian SMAEs to complex and multidimensional risks, and caused profound effects on both upstream and downstream stages of their supply chains. In general, Egyptian SMAEs adopted a ‘wait-and-see’ approach to cope with such Covid-19 risks and impacts, which was attributed to their lack of sufficient financial resources to develop risk management strategies and formalize structures to deal with unexpected events. Interestingly, the results showed that several business opportunities emerged from pandemic; but SMAEs' resource disadvantages constrained their capacity to seize and exploit these opportunities. Moreover, we found that mitigation strategies adopted by SMAEs present a mediating factor between perceived Covid-19 risks and perceived business opportunities. Overall, our findings call for a paradigm shift in relation to enterprise risk management in developing countries' SMAEs toward more holistic frameworks to enhance their preparedness to future shocks, make mature operational and strategic management decisions, and exploit strategic opportunities.

    An econometric investigation of EU's import demand for fresh potato: a source differentiated analysis focusing on Egypt2022Ingår i: Journal of Agribusiness in Developing and Emerging Economies, ISSN 2044-0839, E-ISSN 2044-0847Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose – A better understanding of the determinants of demand through accurate estimates of the elasticityof import demand can help policymakers and exporters improve their market access and competitiveness. This study analyzed the EU’s demand for imported potato from major suppliers between 1994 and 2018, with the aim to evaluate the competitiveness of Egyptian potato.

    Design/methodology/approach – This study adopted an import-differentiated framework to investigatedemand relationships among the major potato suppliers to the EU’s. To evaluate the competitiveness of Egyptian potato on the EU market, expenditure and price demand elasticities for various suppliers werecalculated and compared.

    Findings – The empirical results indicated that as income allocation of fresh potatoes increases, theinvestigated EU markets import more potatoes from other suppliers compared to imports from Egypt. The results show that EU importers may switch to potato imports from other suppliers as the import price ofEgyptian potatoes increases, which enter the EU markets before domestically produced potatoes are harvested.

    Research limitations/implications – Due to data unavailability, the present study relied on yearly data onquantities and prices of EU potato imports. A higher frequency of observations should allow for consideringseasonal effects, and thereby providing a more transparent picture of market dynamics and demand behaviorof EU countries with respect to potato import from various sources of origin.

    Originality/value – The study used a system-wide and source differentiated approach to analyze importdemand. In particular, the empirical approach allowed for comparing different demand models (AIDS,Rotterdam, NBR and CBS) to filter out the superior and most suitable model for that data because the suitabilityand performance of a demand model depends rather on data than on universal criteria.
