Productivity Premia for German Manufacturing Firms Exporting to the Euro-Area and Beyond: First Evidence from Robust Fixed Effects Estimations This paper makes three contributions. (1) It summarizes in tabular form a recent literature made of 36 micro-econometric studies for 16 different countries on the relationship between export destination and firm performance. (2) It reports estimates of t...

This paper starts from a recent case to study how merger analysis in Europe may potentially be improved through simulation analysis. Starting from the geographic market definition in the Merger Decision, we formulate and estimate an oligopoly model with differentiated products. The model is simulated to account for the changed multiproduct ownership structure after the merger. We show how our f...

High levels of inequality are a persistent feature of many rural areas in the developing world. Rural inequality is correlated with major impediments of rural development, such as crime, elite-capture, and lack of collective action. Government transfer programs, such as conditional cash transfer, unemployment insurance, old-age pension or similar programs that target the lower tail of a village...

The basic concept of multiple imputation is straightforward and easy to understand, but the application to real data imposes many implementation problems. To define useful imputation models for a dataset that consists of categorical and of continuous variables with distributions that are anything but normal, contains skip patterns and all sorts of logical constraints is a challenging task. In t...

Essentially all empirical questions that are addressed with sample data require estimates of sampling variance. The econometrics and statistics literatures show that these estimates depend critically on the design of the sample. The sample for the U.S. Current Population Survey (CPS), which serves as the basis for official poverty, unemployment, and earnings estimates, results from a stratified...

Self-Selection and the Efficiency of Tournaments When exogenously imposed, rank-order tournaments have incentive properties but their overall efficiency is reduced by a high variance in performance (Bull, Schotter, and Weigelt 1987). However, since the efficiency of performance-related pay is attributable both to its incentive effect and to its selection effect among employees (Lazear, 2000), i...

Are Refugees Different from Economic Immigrants? Some Empirical Evidence on the Heterogeneity of Immigrant Groups in the United States This paper analyzes how the implicit difference in time horizons between refugees and economic immigrants affects subsequent human capital investments and wage assimilation. The analysis uses the 1980/1990 Integrated Public Use Samples of the Census to study lab...

Garlic constituent diallyl trisulfide (DATS) inhibits growth of cancer cells in vitro and in vivo by causing apoptosis, but the sequence of events leading to cell death is not fully understood. We now show that DATS treatment triggers mitochondria-mediated apoptosis program in human prostate cancer cells (LNCaP, LNCaP-C81, LNCaP-C4-2) irrespective of their androgen responsiveness. Interestingly...

In many economic contexts, an elusive variable of interest is the agent’s expectation about relevant events, e.g. about other agents’behavior. Recent experimental studies as well as surveys have asked participants to state their beliefs explicitly, but little is known about the causal relation between beliefs and other behavioral variables. This paper discusses the possibility of creating exoge...
