Since the end of World War Two, the US unemployment rate has remained constant while the EU unemployment rate started to increase at the beginning of the 1970s. This increase in aggregate unemployment hides dramatic differences across skill groups: the increase has remained fairly small for high-skilled workers, while it is usually considerable for the least skilled workers. What caused these developments still remains a debated issue. A possible explanation is the size of the labor market institutions, much more developed on this side of the Atlantic. To study this question, we construct an intertemporal general equilibrium model. We start from the standard Real Business Cycle (RBC) model and we extend it by adding labor market frictions and institutions (minimum wage, employment protection and unemployment benefits). We also further develop the model along the skill dimension, by assuming that the population is composed of low- and high-skilled workers. The main conclusion is that rigid institutions, and especially rigid wages, may well play an important role, direct or indirect through the interactions with exogenous shocks, to explain the relative rise in the European unemployment rate, and especially the low-skilled unemployment rate. We also show that reductions in employer's contributions, targeted at the minimum wage, lead to a fall in the destruction of the less productive jobs and therefore strongly stimulate low-skilled employment, while increasing the welfare of all individuals.

In the last 30 years the World has been swept by neoliberal doctrine. Under neoliberal conceptions, freedom of the market mechanism has precedence in the process of development. Neoliberalism has had a major impact on the mindset of policymakers, on government strategies for development and on economic performance. This thesis is about the economic consequences of neoliberalism in Brazil. It approaches the problem from a historical perspective. By examining government economic strategies in Brazil from the 1930s through the 1970s it undermines a central neoliberal argument that government interventions in the economy are either inimical or irrelevant to economic development. While government failures did occur indeed, in the Brazilian case it is shown that the government performed a crucial role in this period in building key institutions that guided market forces towards industrial transformation. Since the mid-1970s, Brazil has been a laboratory for neoliberal economic policymaking. Restrictive macroeconomic policies alongside liberalised markets have been the cornerstones of policymaking. The second line of argument developed here is that neoliberalism has since constrained economic development in Brazil. During this period the country has been through several financial crises and has experienced low economic growth and unprecedented unemployment. Compared with the previous period of government-led development, neoliberal policies and institutions fall far behind in terms of overall economic performance. Thirdly, it is argued that under neoliberalism government policy and institutions in Brazil have been directed to satisfy rentiers’ interests at the expense of a socially acceptable economic development. Finally, this thesis calls for the reinstatement of discussion over the government’s role as an agent of a democratic, economic and social ransformation. This is a discussion that has been obstructed by neoliberal doctrine for too long.

The aim of this thesis is to examine the direct effects of labour market institu- tions on unemployment rates in the selected EU Members. For this purpose, we use macroeconomic cross-country, time series analysis for 21 OECD European members over the 2001-2011 period. The results gained from our empirical ana- lysis are rather inconclusive over the possibility to explain the development of European unemployment solely by analysing the effects of labour market insti- tutions. This finding might as well be caused by the volatile evolution of both output and unemployment over the observed period. The importance of busi- ness cycle is confirmed by our results as the measure for the output gap appears highly significant in every model specification. Unlike the majority of previous literature, in our estimates the proxies for macroeconomic shocks do not turn out to be significant. Hence, we decided not to examine mutual interactions between macroeconomic shocks and institutions.

The three essays of this dissertation inform tax policy design. It is a compilation of empirical and experimental research work. The first and the second essays explore the performance of a recent tax policy reform at the sub-national level in India in terms of revenue efficiency as well as economic efficiency. India is among the only three countries in the world to have adopted a sub-national VAT. Therefore, empirically examining its performance not only improves the understanding of this important tax policy reform but also informs tax policy decision-making at the sub-national level in other developing countries. India transitioned to the state-level VAT between the years 2003 and 2008. Among other things, it was expected to achieve revenue growth and decrease tax cascading on commodities by improving economic efficiency of the indirect tax system. In the first essay, I model the impact of the VAT on revenue by adding revenue dependent administrative and compliance costs associated with taxation to an existing model developed by Keen and Lockwood (2010). The theoretical results show that replacing one type of indirect tax with another improves long-run revenue efficiency only if there is a net decrease in the administrative, compliance and distortionary costs of taxation at the margin. I then compile a unique state-level dataset for the years 1990 to 2010 to determine changes in the long-run revenue efficiency from the use of the VAT. This essay contributes to the literature by extending an existing revenue efficiency model and testing it in the unique situation of India’s sub-national VAT. The results reveal a significant improvement in the long-run revenue efficiency of the sales tax instrument used by state governments. The model implies this improvement is driven by a net fall in the marginal taxation costs from the use of the state-level VAT. This finding has important implications on the role of a sub-national VAT in the future as an effective tax instrument in the developing countries. The second essay appeals to the general theory of tax incidence which suggests that a VAT will have less impact on prices than a traditional turnover tax because the VAT does not “get stuck” in the production process as a turnover tax does. The impact should be larger for goods that have more components to the production process as the tax then “touches” more of the final product. In this essay I measure the change in the level of tax cascading with VAT by using multiple waves of the state- and household-level expenditure surveys. Specifically I test the impact of the VAT on the real consumption of households on a variety of consumption goods. I find the biggest significant decrease in the tax cascading burden of the long-term durable goods which essentially involve the maximum production components. This result is found in the 18 more developed states of India which are the focus of the empirical analysis due to data constraints. The third essay is an experimental research which looks at the influence of institutions on the economic burden of an excise tax. The traditional long-run tax incidence theory establishes that the economic incidence of an excise tax is independent of the assignment of the liability to pay tax. However, the theory is silent on the possible effects of the market institutions on tax incidence. Since all markets need an institution to function and every market institution has its own unique price and quantity determination property, it is important to understand its bearings on the incidence of taxes. Existing experimental research has tested economic incidence under many different market institutions but no previous research systematically analyzes and compares the incidence of a unit tax under two important market institutions we deal with in everyday life. One of these institutions is posted offer which dominates the consumer goods markets in developed countries and the other is double auction which is frequently observed in developing countries. I report a significant impact of these market institutions on tax incidence. In particular, I find that consumers bear a much higher burden of a unit tax in the posted offer markets as compared to the double auction markets and their burden further increases when the liability to pay the tax is on the seller.

This thesis studies the cyclical aspect of job polarization in Europe. Contributions include offering a comparison to the findings of previous research on the United States, and extending the analysis by introducing labor market institutions. The analysis is done in two parts, first showing that the observed link between job polarization and jobless recoveries in the US is observed in Europe, but not across all countries and business cycles. In Scandinavia, the process of job polarization appears smoother than the spurts observed in the US. The second part involves regression analyses of the relationship between labor market institutions, the business cycle and occupational employment. The results indicate that stricter labor market institutions are less robustly associated with Routine employment than other occupational groups and that Routine employment is more sensitive to the business cycle than other types of employment. Further, rigid labor market institutions may prevent some of the Routine decline associated with economic downturns, while not necessarily affecting the long run employment. Limitations of the analysis regards rough estimates of the key variables, number of observations and the lack of identification associated with cross-country analyses.

RNDr. Jiří Blažek, PhD. Ústí nad Labem 2010 2 CONTENT Introduction and theoretical framework Hypotheses and structure of the dissertation Conclusion Selected literature 3 Introduction and theoretical framework Current research of regional development sees themes focused on the institutional context of regional development in the foreground [Rutten, Boekema 2007], regional mechanisms are evaluated, key categories and groups of actos for the long-term improvement of the competitiveness of the region are sought [Breschi, Malerba 2007]. The theory is that regional development operates with various actors concepts. Traditional neo-classic approaches stemming from the individualized concept of a actor in the market environment are often completed with institutional approaches that highlight the understanding of the actor as an entity interwoven by many specific market mechanisms and social structures - production chains, subcontractor relationships and further formal and informal boundaries that define market potential. From the institutional economy point of view, the actor...

This thesis contributes to the literature on making agricultural markets work for the poor, with specific reference to Ethiopia. It contains three substantive chapters, which may be read independently. The chapters use primary surveys with traders conducted in 2002 (chapters 2 and 3) and 2007 (all the chapters).Chapter 1 investigates Ethiopian traders’ decision on whether and how much to use brokers. Results shine light on how the Ethiopia Commodity Exchange (ECX), which recently formalized the brokerage functions, could be most beneficial for the functioning of agricultural markets. We show that the ECX could consider introducing new food crops in the trading system, offering warehouse receipt financing to its clients, and spreading the network of its warehouses throughout the country. Chapter 2 inquires whether the focus on technological and institutional upgrading is sufficient to make Ethiopian agricultural markets more efficient and if the existence of many small intermediaries causes market inefficiency. Findings suggest that, when transporters are used, transport costs could be reduced by avoiding trans-shipment, and reducing the number of times the transporter has to stop to allow for cargo loading and off-loading. No evidence is found for increasing returns to transaction size. Chapter 3 conceptualizes the notion of market integration as ‘tradability’ and analyses what determines the likelihood of market diversification among Ethiopian traders. The variables that are found to significantly impact on this probability are location (which is correlated with access to asphalt roads), availability of market information, traders’ educational level, access to commercial finance and storage capacity. Results indicate that market fundamentals affected the likelihood of market diversification more in 2007, when prices were rapidly surging, than in 2001 when prices were decreasing. The findings of this thesis support the ‘getting markets right’ school, in that incentives, infrastructure and institutions are essential for market development, and long-distance coordination of market exchange can be achieved through public-private cooperation.

While linkages between some macroeconomic phenomena (e.g. unemployment, GDP growth) and suicide rates in some countries have been explored, only one study, hitherto, has established a causal relationship between fiscal consolidation and suicide, albeit in a single country. This study examines the impact of budget consolidation on suicide mortality across all Eurozone peripheral economies, while controlling for various economic and sociodemographic differences. The impact of fiscal adjustments is found to be gender, age and time specific. In particular, fiscal consolidation has short-, medium- and long-run suicide increasing effects on the male population between 65 and 89 years of age. A one percentage point reduction in government spending is associated with an 1.39%, 2.35% and 2.64% increase in the short-, medium- and long-run, respectively, of male suicides rates between 65 and 89 years of age in the Eurozone periphery. These results are highly robust to alternative measures of fiscal consolidation. Unemployment benefits and substantial employment protection legislation seem to mitigate some of the negative effects of fiscal consolidation on suicide mortality. Plausible explanations for these impacts are provided and policy implications drawn. (authors' abstract) / Series: Department of Economics Working Paper Series

The thesis consists of three papers, summarized as follows.        "The Determinants of Labour Market Institutions: A Panel Data Study"    This paper analyses the argument that labour market institutions can be thought of as devices for social insurance. It investigates the hypotheses that a country's exposure to external risk and ethnic fractionalisation are correlated with labor market institutions. Extreme bounds analysis with panel data of fourty years indicates that countries that are more open to international trade have stricter employment protection, strong unions, and a more coordinated wage bargaining process. Moreover, there is evidence that union density is negatively associated with the degree of ethnic fracationalisation.  "Why do Some Studies Show that Generous Unemployment Benefits Increase Unemployment Rates? A Meta-Analysis of Cross-Country Studies"    This paper investigates the hypothesis that generous unemployment benefits give rise to high levels of unemployment by systematically reviewing 34 cross-country studies. In contrast to conventional literature surveys, I perform a meta-analysis which applies regression techniques to a set of results taken from the existing literature. The main finding is that the choice of the primary data and estimation method matter for the final outcome. The control variables in the primary studies also affect the results. "The Effects of Trade on Unemployment: Evidence from 20 OECD countries"    This study empirically investigates if international trade has an impact on aggregate unemployment in the presence of labour market institutions. Using data for twenty OECD countries for the years 1961-2008, this study finds that an increase in trade leads to higher aggregate unemployment as it interacts with rigid labour market institutions, whereas it may reduce aggregate unemployment if the labour market is characterised by flexibility. In a country with the average degree of the labour market rigidities, an increase in trade has no significant effect on unemployment rates.
