We propose an immigration policy based on the model of cooperatives. Incoming migrants have to acquire a participation certificate. In exchange, the immigrants may enter the country of choice without danger. The revenue goes to the country of the recipient nation rather than to human smugglers....

This paper investigates whether risk aversion and impatience are correlated with cognitive ability. We conduct incentive compatible choice experiments measuring risk aversion, and impatience over an annual time horizon, for a representative sample of roughly 1,000 German adults. A measure of...

The paper evaluates the working of German CFC rules that restrict the use of foreign subsidiaries located in low-tax countries to shelter passive investment income from home taxation. While passive investments make up a significant fraction of German outbound FDI, we find that German CFC rules...

In this paper, we use data from the German PISA 2003 sample to study the effects of central exit examinations on student performance, student attitudes, and teacher behavior. Unlike earlier studies we use (i) a value-added measure to pin down the effect of central exit exams on learning in the...

We examine evidence for a systematic underperformance of Germany's state-owned banks in the current financial crisis and study if the bank losses can be traced to the quality of bank governance. For this purpose, we examine the biographical background of 593 supervisory board members in the 29...

This study is framed against the increasingly stringent environmental demands on the pulp and paper industry since the late-1980s to reduce water and air pollution, and the global economic slowdown of the early-1990s. The primary focus of this paper is an observation-based analysis conducted by...

We derive the optimal contract between a principal and a liquidity-constrained agent in a stochastically repeated environment. The contract comprises a court-enforceable explicit bonus rule and an implicit fixed salary promise that must be self-enforcing. Since the agent's rent increases with...

This paper analyses the effects of education signals for Ethnic Germans and Germans without a migration background (Native Germansʺ). We base our analysis on a sorting model with productivity enhancing effects of education. We compare whether the signalling value differs between the migrants...

The paper aims at assessing discrete complementarities in innovation policies in the context of the Brazilian industry in 2003. The paper considers the approach advanced by Mohnen and and Röller [European Economic Review, 2005] that focuses on supermodularity and submodularity tests for...

We run a large-scale natural field experiment to evaluate alternative strategies to enforce compliance with the law. The experiment varies the text of mailings sent to potential evaders of TV license fees. We find a strong alert effect of mailings, leading to a substantial increase in...
