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,...

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...

A central concern in economics is to understand the interplay between institutions and labor markets. In this paper we argue that laboratory experiments are a powerful tool for studying labor market institutions. One of the most important advantages is the ability to implement truly exogenous...

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...

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 provides field experimental evidence on the prevalence and determinants of discrimination and in-group favoritism in trust decisions. We observe choices of about 1,000 inhabitants of the city of Zurich who take part in a sequential trust game, in which first movers can condition their...

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...

When unemployment prevails, relations with a particular firm are valuable for workers. As a consequence, a worker may adhere to an implicit agreement to provide high effort, even when performance is not third-party enforceable. But can implicit agreements - or relational contracts - also...

We provide evidence on how two important types of institutions - dismissal barriers, and bonus pay - affect contract enforcement behavior in a market with incomplete contracts and repeated interactions. Dismissal barriers are shown to have a strong negative impact on worker performance, and...

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...
