deutscher Titel: Makroökonomische Herausforderungen für die Eurozone und die Beitrittskandidaten
Abstract: The conduct of effective economic policy faces a multiplicity of macroeconomic challenges, which requires a wide scope of theoretical and empirical analyses. With a focus on the European Union, this doctoral dissertation consists of two parts which make empirical and methodological contributions to the literature on forecasting real economic activity and on the analysis of business cycles in a boom-bust framework in the light of the EMU enlargement. In the first part, we tackle the problem of publication lags and analyse the role of the information flow in computing short-term forecasts up to one quarter ahead for the euro area GDP and its main components. A huge dataset of monthly indicators is used to estimate simple bridge equations. The individual forecasts are then pooled, using different weighting schemes. To take into consideration the release calendar of each indicator, six forecasts are compiled successively during the quarter. We find that the sequencing of information determines the weight allocated to each block of indicators, especially when the first month of hard data becomes available. This conclusion extends the findings of the recent literature. Moreover, when combining forecasts, two weighting schemes are found to outperform the equal weighting scheme in almost all cases. In the second part, we focus on the potential accession of the new EU Member States in Central and Eastern Europe to the euro area. In contrast to the discussion of Optimum Currency Areas, we follow a non-standard approach for the discussion on abandonment of national currencies the boom-bust theory. We analyse whether evidence for boom-bust cycles is given and draw conclusions whether these countries should join the EMU in the near future. Using a broad range of data sets and empirical methods we document credit market imperfections, comprising asymmetric financing opportunities across sectors, excess foreign currency liabilities and contract enforceability problems both at macro and micro level. Furthermore, we depart from the standard analysis of comovements of business cycles among countries and rather consider long-run and short-run comovements across sectors. While the results differ across countries, we find evidence for credit market imperfections in Central and Eastern Europe and different sectoral reactions to shocks. This gives favour for the assessment of the potential euro accession using this supplementary, non-standard approach.

Do Banks Benefit from Internationalization? Revisiting the Market Power-Risk Nexus
Claudia M. Buch, C. T. Koch, Michael Koetter
Abstract
Recent developments on international financial markets have called the benefits of
bank globalization into question. Large, internationally active banks have
acquired substantial market power, and international activities have not
necessarily made banks less risky. Yet, surprisingly little is known about the
actual link between bank internationalization, bank risk, and market power.
Analyzing this link is the purpose of this paper. We jointly estimate the
determinants of risk and market power of banks, and we analyze the effects of
changes in terms of the number of foreign countries (the extensive margin) and
the volume of foreign assets (the intensive margin). Our paper has four main
findings. First, there is a strong negative feedback effect between risk and market
power. Second, banks with higher shares of foreign assets, in particular those held
through foreign branches, have higher market power at home. Third, holding
assets in a large number of foreign countries tends to increase bank risk. Fourth,
the impact of internationalization differs across banks from different banking
groups and of different size.

International Bank Portfolios: Short- and Long-run Responses to Macroeconomic Conditions
S. Blank, Claudia M. Buch
Review of International Economics,
Nr. 2,
2010
Abstract
International bank portfolios constitute a large component of international country portfolios. Yet, banks’ response to international macroeconomic conditions remains largely unexplored.We use a novel dataset on banks’ international portfolios to answer three questions. First, what are the long-run determinants of banks’ international portfolios? Second, how do banks’ international portfolios adjust to short-run macroeconomic developments? Third, does the speed of adjustment change with the degree of financial integration?We find that, in the long-run, market size has a positive impact on foreign assets and liabilities. An increase in the interest differential between the home and the foreign economy lowers foreign assets and increases foreign liabilities. Foreign trade has a positive impact on international bank portfolios, which is independent from the effect of other macroeconomic variables. Short-run dynamics show heterogeneity across countries, but these dynamics can partly be explained with gravity-type variables.

Monopsonistic Labour Markets and the Gender Pay Gap: Theory and Empirical Evidence
Boris Hirsch
Lecture Notes in Economics and Mathematical Systems,
Nr. 639,
2010
Abstract
This book investigates models of spatial and dynamic monopsony and their application to the persistent empirical regularity of the gender pay gap. Theoretically, the main conclusion is that employers possess more monopsony power over their female employees if women are less driven by pecuniary considerations in their choice of employers than men. Employers may exploit this to increase their profits at the detriment of women’s wages. Empirically, it is indeed found that women’s labour supply to the firm is less wage-elastic than men’s and that at least a third of the gender pay gap in the data investigated may result from employers engaging in monopsonistic discrimination. Therefore, a monopsonistic approach to gender discrimination in the labour market clearly contributes to the economic understanding of the gender pay gap. It not only provides an intuitively appealing explanation of the gap from standard economic reasoning, but it is also corroborated by empirical observation.

The Gender Pay Gap under Duopsony: Joan Robinson meets Harold Hotelling
Boris Hirsch
Scottish Journal of Political Economy,
Nr. 5,
2009
Abstract
This paper presents an alternative explanation of the gender pay gap resting on a simple Hotelling-style duopsony model of the labour market. Since there are only two employers, equally productive women and men have to commute and face travel cost to do so. We assume that some women have higher travel cost, e.g., due to more domestic responsibilities. Employers exploit that women on average are less inclined to commute and offer lower wages to all women. Since women's firm-level labour supply is for this reason less wage-elastic, this model is in line with Robinson's explanation of wage discrimination.

Barriers to Internationalization: Firm-Level Evidence from Germany
Claudia M. Buch
IAW Discussion Paper No. 52,
2009
Abstract
Exporters and multinationals are larger and more productive than their domestic
counterparts. In addition to productivity, financial constraints and labor market
constraints might constitute barriers to entry into foreign markets. We present new
empirical evidence on the extensive and intensive margin of exports and FDI based on detailed micro-level data of German firms. Our paper has three main findings. First, in line with earlier literature, we find a positive impact of firm size and productivity on firms’ international activities. Second, small firms suffer more frequently from financial constraints than bigger firms, but financial conditions have no strong effect on internationalization. Third, labor market constraints constitute a more severe barrier to foreign activities than financial constraints. Being covered by collective bargaining particularly impedes international activities.

Openness and Growth: The Long Shadow of the Berlin Wall
Claudia M. Buch, Farid Toubal
Journal of Macroeconomics,
Nr. 3,
2009
Abstract
The question whether international openness causes higher domestic growth has been subject to intense discussions in the empirical growth literature. This paper addresses the issue in the context of the fall of the Berlin Wall in 1989. We analyze whether the slow convergence in per capita incomes between East and West Germany and the lower international openness of East Germany are linked. We address the endogeneity of openness by adapting the methodology proposed by Frankel and Romer (1999) to a panel framework. We instrument openness with time-invariant exogenous geographic variables and time-varying exogenous policy variables. We also distinguish the impact of different channels of integration. Our paper has three main findings. First, geographic variables have a significant impact on regional openness. Second, controlling for geography, East German states are less integrated into international markets along all dimensions of integration considered. Third, the degree of openness for trade has a positive impact on regional income per capita.

Will There Be a Shortage of Skilled Labor? An East German Perspective to 2015
Herbert S. Buscher, Eva Dettmann, Marco Sunder, Dirk Trocka
IWH Discussion Papers,
Nr. 13,
2009
Abstract
We analyze the supply and demand of skilled labor in an East German federal state, Thuringia. This state has been facing high unemployment in the course of economic transformation and experiences population ageing and shrinking more rapidly than most West European regions. In a first step, we use extrapolation techniques to forecast labor supply and demand for the period 2009-2015, disaggregated by type of qualification. The analysis does not corroborate the notion of an imminent skilled-labor shortage but provides hints for a tightening labor market for skilled workers. In the second step, we ask firms about their appraisal of future recruitment conditions, and both current and planned strategies in the context of personnel management. The majority of firms plan to expand further education efforts and hire older workers. The study closes with policy recommendations to prevent occupational mismatch.
