Abstract
This paper examines which emerging market regions form optimum currency areas (OCAs) by assessing the symmetry of macroeconomic shocks. We extend the output-prices-VAR framework by adding net exports and the real effective exchange rate as endogenous variables. Based on theoretical considerations, we derive which shocks affect these variables in the long run: shocks to labor productivity, foreign trade, labor supply, and money supply. The considered economies of Central and Eastern Europe, the Commonwealth of Independent States, East and Southeast Asia, and South Asia, exhibit large enough shock symmetry to form a currency union; the economies of Africa, Latin America, and the Middle East do not.

Abstract
The aim of this study is to assess the contributions of investment banking to the economy with a particular focus on the German economy. To this end we analyse both the economic benefits and the costs stemming from investment banking.
The study focuses on investment banks as this part of banking is particularly relevant for financing companies as well as the development and use of specific products to support the needs of private and professional clients. The assessment of benefits and costs of investment banking has been conducted from a European perspective. Nevertheless there is a focus on the German economy to allow a more detailed analysis of certain aspects as for example the use of derivatives by German companies, the success of M&As in Germany or the effect of securitization on loan supply and GDP in Germany. For comparison purposes other European countries and also the U.S. have been taken into account.
The last financial crisis has shown the negative impacts of banks on the financial system and the whole economy. In a study on the contribution of investment banks to systemic risk we quantify the negative side of the investment banking business.
In the last part of the study we assess how the effects of regulatory changes on investment banking. All important changes in banking and capital market regulation are taken into account such as Basel III, additional capital requirements for systemically important financial institutions, regulation of OTC derivatives and specific taxes.

Trade Misinvoicing: The Dark Side of World Trade

No. 8,

Abstract
We analyse the determinants of trade misinvoicing using data on 86 countries from 1980 to 2005. In a simple microeconomic framework, we derive the determinants of four different types of trade misinvoicing taking into account that only the financial incentives determine whether and how much exports/imports to underinvoice or overinvoice, whereas the deterrents only affect the extent of misinvoicing. The hypothesised determinants are tested using data on discrepancies in bilateral trade with the United States. We find that the black market premia and tariffs motivate illegal trading activities. Higher financial penalties effectively act as a deterrent to this crime.

On the Economic Architecture of the Workplace: Repercussions of Social Comparisons among Heterogeneous Workers
Oded Stark, Walter Hyll
Journal of Labor Economics,
No. 2,
2011
Abstract
We analyze the impact on a firm’s profits and optimal wage rates, and on the distribution of workers’ earnings, when workers compare their earnings with those of co-workers. We consider a low-productivity worker who receives lower wage earnings than a high-productivity worker. When the low-productivity worker derives (dis)utility not only from his own effort but also from comparing his earnings with those of the high-productivity worker, his response to the sensing of relative deprivation is to increase the optimal level of effort. Consequently, the firm’s profits are higher, its wage rates remain unchanged, and the distribution of earnings is compressed.

Currency Crisis Prediction Using ADR Market Data: An Options-based Approach
Stefan Eichler, Dominik Maltritz
International Journal of Forecasting,
No. 4,
2010
Abstract
During capital control episodes, large price deviations between American Depositary Receipts (ADR) and their underlying stocks signal that a currency crisis is about to occur. We interpret this price spread as the price of a call option. Using option pricing theory we derive detailed information about both the probability of a currency crisis and the expected magnitude of devaluation. Analyzing daily ADR market data preceding the Venezuelan crisis (1996), our approach predicts crisis probabilities of almost 100% and forecasts the exchange rate after floating quite accurately. During the Argentine crisis (2002), the estimated exchange rates are similar to the actual ones.

Abstract
Die Politik in Europa will bei der Regulierung der Banken und Finanzmärkte Handlungswillen demonstrieren. Nahm man im Jahr 2009 schon Banker-Boni, Rating-Agenturen und Derivate an die Leine, haben die EU-Finanzminister jüngst den Aufbau europäischer Aufsichtsbehörden für Banken, Versicherungen und Wertpapiermärkte beschlossen. Grundsätzlich ist eine Zentralisierung von Aufsichtskompetenzen auf europäischer Ebene angemessen. Finanzinstitute werden nicht durch Staatsgrenzen eingeschränkt und verteilen Geschäftsteile, auch in Reaktion auf nationale Aufsichtsunterschiede, auf die für sie günstigsten Länder. Zudem haben die nationalen Aufsichtsbehörden in der Krise auf Probleme im Finanzsektor nicht immer angemessen reagiert, auch weil sie deren ganzes Ausmaß nicht erfassen wollten oder konnten.

Has the Euro Increased International Price Elasticities?

IWH Discussion Papers,
No. 18,

published in: Empirica
Abstract
This paper analyzes the role of common data problems when identifying structural breaks in small samples. Most notably, we survey small sample properties of the most commonly applied endogenous break tests developed by Brown, Durbin, and Evans (1975) and Zeileis (2004), Nyblom (1989) and Hansen (1992), and Andrews, Lee, and Ploberger (1996). Power and size properties are derived using Monte Carlo simulations. Results emphasize that mostly the CUSUM type tests are affected by the presence of heteroscedasticity, whereas the individual parameter Nyblom test and AvgLM test are proved to be highly robust. However, each test is significantly affected by leptokurtosis. Contrarily to other tests, where skewness is far more problematic than kurtosis, it has no additional effect for any of the endogenous break tests we analyze. Concerning overall robustness the Nyblom test performs best, while being almost on par to more recently developed tests in terms of power.

Interactive Dynamic Capabilities and Regenerating the East German Innovation System

Contributions to Political Economy,
2010
Abstract
The paper sets out a specification of capabilities and competencies derived from Sen’s work on consumer capabilities and welfare economics. This approach is one that proves remarkably easy to generalise, first to producer and supplier capabilities, and thence to interactive and dynamic capabilities. The approach is then applied via the consequential perspectives of regional systems of innovation and network alignment to the case of the efforts to regenerate the innovation system in East Germany since reunification. It is seen that this process can be divided into three periods, of which the most recent appears to meet some of the theoretical requirements for effective interactive capabilities. It is less clear that the criteria for dynamic capabilities—which involve considerations of speed-up and flexibility, to meet the market requirements in real time—have yet been taken sufficiently seriously.
