"Prominent economic theories have emphasized the role of commonly held perceptions and expectations for determining macroeconomic outcomes. A key empirical question is how such collectively held beliefs are formed. We use the FIFA World Cup 2006 as a natural experiment. We provide direct...

Experimental evidence has convincingly shown the existence of reciprocal inclinations, i.e., a tendency for people to respond in-kind to hostile or kind actions. Little is known, however, about: (i) the prevalence of reciprocity in the population, (ii) individual determinants of reciprocity,...

The paper uses a new German employer survey on wage setting practices to analyze incidence and sources of nominal wage rigidity in services vs. manufacturing. We observe that wage freezes are significantly more frequent and wage cuts less frequent in services. Reasons preventing wage cuts...

We investigate whether two crucial determinants of economic decision making willingness to take risks and willingness to trust other people are transmitted from parents to children. Our evidence is based on survey questions that ask about these attitudes directly, and are good measures in the...

In the debate on in-work benefits in Germany it is often overlooked that such subsidies may only be effective if basic minimum income is remarkably decreased for those who are employable. However, proposals following this principle will hardly achieve political consensus as can be derived from...

Is the way that people make risky choices, or tradeoffs over time, related to cognitive ability? This paper investigates whether there is a link between cognitive ability, risk aversion, and impatience, using a representative sample of the population and incentive compatible measures. We conduct...

This paper analyzes the effectiveness of occupational training programs for the unemployed before and after the substantial amendments in German labor market legislation known as Hartz reforms. Based on the official evaluation of the reforms, we show that program impacts vary much across...

Starting in January 2003, Germany implemented the first two so-called Hartz reforms, followed by the third and fourth packages of Hartz reforms in January 2004 and January 2005, respectively. The aim of these reforms was to accelerate labor market flows and reduce unemployment duration. Without...

The paper investigates the role of social norms as a determinant of individual attitudes by analyzing risk proclivity reported by immigrants and natives in a unique representative German survey. We employ factor analysis to construct measures of immigrants' ethnic persistence and assimilation....

The paper analyzes the labor market impact of migration by exploiting variation in the labor supply of foreigners across groups of workers with the same level of education but different work experience. Estimates on the basis of German register data for the period 1975-97 do not confirm the...
