Charles University in Prague Faculty of Social Sciences Institute of Economic Studies Three Essays on Labor Market Institutional Environment Dissertation Thesis Kamila Fialová Prague 2012 Abstract This thesis consists of three papers about labor market institutional environment. The first paper "Labor Market Institutions and Their Effect on Labor Market Performance in the New EU Member Countries" estimates the effects of labor market institutions on various performance indicators (unemployment, long-term unemployment, employment, activity rate) in European countries. The results confirm that high taxes increase unemployment, whereas active labor market policies tend to reduce it. The paper also shows that stricter employment protection, higher taxes, and a larger economic burden represented by the minimum wage decrease employment and activity rates. The second paper "Labor Market Institutions and Their Impact on Shadow Economies in Europe" analyzes the role of labor market institutions in explaining developments of shadow economies in European countries using several alternative measures of the shadow sector. The results indicate that the one institution that unambiguously increases shadow production and employment is strict employment protection legislation. Other labor market institutions have less...

The thesis is aimed at estimate of calculation of tax evasions at value-added tax (VAT) in the Czech Republic between 2005 and 2011. The estimates are executed on the basis of the concept of tax gap. Tax gap compares theoretically calculated tax amount with the real tax amount. Results of the calculations are compared to the results of calculations of cumulative studies of tax gap executed in the countries of European Union. The issue of grey economy is also topic of the thesis and different approaches to calculations of grey economy are mentioned. Topics like tax-evasions causes, tax-evasions types and ways of its solving follow. Conclusion of the thesis includes questionnaire survey among payers of VAT. Survey is especially aimed at tax evasions and possible solutions to them.

The difficulty of transforming war economies into peace economies has become increasingly problematic in the search for long-term peace and stability in Africa. In many African countries such as Sierra Leone, Angola and the Democratic Republic of Congo, conflict actors have created distinct war economies in order to maintain the conflict in these countries. The enduring nature of the war economies presents a unique challenge to actors involved in ensuring that peace returns to a country by applying a peacebuilding strategy. The economic environment during a conflict has a vast influence on a post-conflict economy and a post-conflict reconstruction strategy. Although post-war rebuilding occurred during the reconstruction of Europe and Japan after the Second World War, the terms "post-conflict peacebuilding" and "post-conflict reconstruction" have only came to prominence during the mid-1990s. Using the case study of Sierra Leone, this study explores the challenge of war economies and its impact on post-conflict reconstruction. Sierra Leone presents an appealing case study as the country experienced a very profitable war economy during the armed conflict in the country between 1991 and 2002, and continues to struggle to transform this war economy into a peace economy. The case study of Sierra Leone is well researched, however, most studies focus on the conflict period, and only briefly look at the post-conflict period. In addition, discussions of post-conflict reconstruction in Sierra Leone have failed to adequately address the challenges presented by the war economy. This study uses existing analyses about the war economy in Sierra Leone, and links these to the current post-conflict reconstruction strategy, focusing specifically on the economic dimension. Therefore, this study represents a departure from traditional approaches to exploring war economies because it considers the direct impact these economic systems have on the process of post-conflict reconstruction. / Dissertation (MA)--University of Pretoria, 2010. / Political Sciences / unrestricted

The dissertation “Informal Economic Activities” takes a comprehensive approach to the informal economy by studying traditional shadow economic activities, household DIY activities, and the smuggling of illegal and legal goods. Chapter 2 analyzes shadow economic and DIY activities and presents a dual estimation for the development of both types of informal economic activities in Germany from 1970 to 2005. It also considers the impact of German reunification on shadow economic and DIY activities and employs a proper estimate of domestic currency in circulation within Germany as an indicator variable for the shadow economy. Chapter 3 studies an informal economic activity that has attracted much attention recently: legal goods smuggling, or the illegal trade of otherwise legal goods. The main channel of this type of smuggling is the falsification of trade documents. By reporting false amounts of exports and/or imports to authorities smugglers, or trade misinvoicers, seek to avoid paying taxes and/or tariffs. Chapter 4 widens the analysis of smuggling to the smuggling of illegal goods and studies the smuggling of legal and illegal goods across the U.S.-Mexico border in order to improve the understanding of illegal trade. Studying the U.S.-Mexican case is particularly interesting as most illegal drugs and immigrants enter the United States via the Mexican border. The empirical analyses in the dissertation “Informal Economic Activities” are based on structural equation models (SEMs). The results demonstrate that the informal economy is significant and that growth of the informal economy is not exclusive to developing countries, although it is a more serious problem in these countries. Moreover, although the informal economy covers a wide range of rather diverse economic activities, the dissertation works out that a few similarities exist. These are important, especially for policymakers, in first understanding what drives informal economic activities and second designing appropriate policies to deter them.

The subject of this thesis are now almost extinct brick and mortar video rental stores that were a crucial film distribution window between theatre and television premiere only a few decades ago. The research focuses on the arrival of video rental stores run by small private entrepreneur in Prague 1990-1995 right after the country reinstalled its market economy. The text tries to reconstruct, describe and analyse six particular places of business via interviews with their owners and further archive materials - and in addition maybe ascertain reasons of their closure / continuance after 1995. Part of the thesis is also a list of 90 addresses of Prague video rental stores from around that time and basic figures of their arrangement.

Cette thèse s’intéresse aux effets macroéconomiques du développement financier sur la vulnérabilité dans l’emploi dans les pays émergeants et en développement. Dans le premier chapitre, nous montrons que l’accès au crédit et les inégalités de revenu augmentent le travail des enfants surtout dans les pays à forte inégalité ou à faible revenu. Ce résultat indique que les parents tendent à investir leur crédit dans des projets qui accroissent le coût d’opportunité de l’éducation et le bénéfice attendu du travail des enfants. Ainsi, nous démontrons qu’un meilleur contrôle de la corruption permet d’améliorer l’efficacité du développement financier ainsi que des dépenses d’éducation en vue de réduire le travail des enfants. Cela passe notamment par une amélioration de la qualité de l’éducation. Dans le second chapitre, nous démontrons qu’un meilleur accès aux services financiers ainsi qu’une réduction des contraintes en termes d’utilisation de ces produits réduit la proportion de travailleurs pauvres. Cet effet est plus important en cas d’instabilité macroéconomique. De plus, ce meilleur accès bénéficie également aux non pauvres qui étaient précédemment exclus, ces derniers étant plus à même d’investir et de réduire indirectement la proportion de travailleurs pauvres via une croissance plus forte. Les résultats du troisième chapitre suggèrent qu’aussi bien le développement financier et les transferts de fonds des migrants peuvent limiter la prolifération du secteur informel. Cependant, ils tendent à être substituts, avec notamment un faible niveau de développement financier initial qui est compensé par l’utilisation des transferts de fonds. Finalement dans le chapitre 4, nous passons en revue des produits financiers flexibles et innovants qui pourraient permettre aux plus vulnérables de mieux faire face aux chocs. Nos résultats suggèrent que ces produits doivent être conçus de manière à offrir dans un premier temps des produits d’épargne en supprimant notamment les frais d’ouverture de compte. Leur utilisation devrait permettre de produire de l’information sur les emprunteurs notamment sur la base de l’historique des versements et leur fréquence. Ainsi en cas de choc, l’épargne accumulée peut servir de garantie pour le prêt complété si nécessaire par des produits d’assurance. Le « mobile banking » peut également servir pour la diffusion des produits flexibles et dans une plus large mesure de support pour accroître le niveau de bancarisation, vu le nombre croissant de personnes utilisant le téléphone portable. / This thesis explored the macroeconomic effects of financial development on the most vulnerable workers in developing and emerging countries. Chapter one focuses on child labor. Our results suggest that child labor is positively associated to financial development and inequality particularly in countries with high level of income inequalities and low level of income. In fact, with access to credit, households tend to invest in productive activities which increase the opportunity cost of education and the returns from child labor. Hence, we demonstrate that a better control of corruption makes financial development as well as education spending more effective in reducing child labor by improving education quality. In the second chapter, we show that more bank branches and limiting barriers to use financial services reduce the proportion of working poor. This result is more relevant in countries hit by macroeconomic shocks and a better access to financial services also benefits to the excluded non-poor who can in turn invest and reduce poverty. In the third chapter, we find that both financial development and remittances tend to reduce the spread of the shadow economy by channelling funds to the more productive activities. Moreover, they tend to be substitutes, indicating that households rely on remittances in countries with low level of financial development. Finally, chapter four reviews innovative flexible financial products which can be used to help the more vulnerable to manage shocks. Our results suggest that, first barriers to open saving and checking accounts (like opening fees) need to be suppressed in order to increase the use of these services, generating more information on potential borrowers on the basis of the history and frequency of payments. Then, accumulated savings can be used as collateral for loan supplemented by insurance services. Mobile banking could also serve as support for flexible financial services.Keywords: Financial development, financial services; child labor, decent work, vulnerability, informal sector shadow economy, underground economy, institutions, inequality, working poverty, developing countries, trickle-down effect, remittances, microfinance, flexibility, discipline, risk, shocks, index-based insurance, combined products.
