"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,...

A key open question for theories of reference-dependent preferences is what determines the reference point. One candidate is expectations: what people expect could affect how they feel about what actually occurs. In a real-effort experiment, we manipulate the rational expectations of subjects...

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...

We use natural experiments plausibly exogenous, anticipated increases in the piece rate to study how effort responds to incentives. Our first finding, like some previous studies, lends little support to the view that incentives increase effort: raising the piece rate has zero effect on total...

"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...

We analyze the impact of imperfect contract enforcement on the emergence of unemployment. In an experimental labor market where trading parties can form long-term employment relationships, we compare a work environment where effort is observable, but not verifiable to a situation where explicit...

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...

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...

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...
