Economically highly developed countries are mostly democratic. But does this association constitute a causal relationship according to which democracy is a determinant of economic development? Or is it, conversely, economic development that paves the way for democratization? This paper gives an...

Standard search theory assumes that individuals know, with certainty, how they compare to competing searchers in terms of ability. In contrast, we hypothesize that searchers are uncertain about relative ability, with important implications for search behavior. We test our hypotheses in a...

This paper presents a model of the labor market in which unemployed workers are uncertain about their relative ability to find a job. Unsuccessful search induces individuals to revise their beliefs downwards. Once self-confidence is sufficiently low, workers become discouraged and give up on...

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...

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...

This paper argues that accounting for the dynamic interactions between endogenous changes in longevity, the education composition of the population, and the associated fertility differential is crucial for understanding the economic and the demographic transition. In the model, heterogeneous...

Using cross-country data, we find evidence for a significant negative interaction effect between democracy and inequality in determining the quality of growth-promoting institutions like rule of law. Democracy is associated with institutions of higher quality when inequality is lower.

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...

Many economic decisions involve a substantial amount of uncertainty, and therefore crucially depend on how individuals process probabilistic information. In this paper, we investigate the capability for probability judgment in a representative sample of the German population. Our results show...

In this paper we investigate the causal effect of life expectancy on economic growth by explicitly accounting for the role of the demographic transition. In addition to focusing on issues of empirical identification, this paper emphasizes the role of the econometric specification. We present a...
