We examine rational learning among expert chess players and how they update their beliefs in repeated games with the same opponent. We present a model that explains how equilibrium play is affected when players change their choice of strategy when receiving additional information from each...

Team success relies on assigning team members to the right tasks. We use controlled experiments to study how roles are assigned within teams and how this affects team performance. Subjects play the takeover game in pairs consisting of a buyer and a seller. Understanding optimal play is very...

Many tournaments are plagued by sabotage among competitors. Typically, sabotage is welfare-reducing, but from an individual's perspective an attractive alternative to exerting positive effort. Yet, given its illegal and often immoral nature, sabotage is typically hidden, making it difficult to...

We examine the strategic sophistication of adolescents, aged 10 to 17 years, in experimental normal-form games. Besides making choices, subjects have to state their first- and second-order beliefs. We find that choices are more often a best reply to beliefs if any player has a dominant strategy...

Many economic decisions are made jointly within households. This raises the question about spouses' relative influence on joint decisions and the determinants of relative influence. Using a controlled experiment (on inter-temporal choice), we let each spouse first make individual decisions and...

The need for efficient coordination is ubiquitous in organizations and industries. The literature on the determinants of efficient coordination has focused on individual decision-making so far. In reality, however, teams often have to coordinate with other teams. We present an experiment with...

This paper uses a social experiment in labour market policy – providing early and intensive monitoring and programme participation in unemployment spells – to assess the nature of labour market policy effectiveness. The experiment was conducted in two counties in Denmark during the winter of...

We use a laboratory experiment to examine whether and to what extent other-regarding preferences of team leaders influence their leadership style in choice under risk. We find that leaders who prefer efficiency or report high levels of selfishness are more likely to exercise an autocratic...

We consider the consequences of working part-time on supplementary unemployment insurance benefits in the Danish labour market. Following the "timing-of-events" approach we estimate causal effects of subsidized part-time work on the hazard rate out of unemployment insurance benefit receipt. We...

Credence goods markets are characterized by asymmetric information between sellers and consumers that may give rise to inefficiencies, such as under- and overtreatment or market break-down. We study in a large experiment with 936 participants the determinants for efficiency in credence goods...
