In models of sequential decision making herd behaviour occurs if the signals smart(dumb) agents receive are (un)correlated and if agents have reputational concerns. We show thatintroducing costly effort to become informed about project payoffs (i) eliminates herdbehaviour and (ii) shifts...

Organization differ in the degree to which they differentiate employees by ability. We analyse how the effect of differentiation on employee morale may explain this variation. By comparing employees using ordinary talk, a manager boosts the self-image of some, but hurts that of others. Whether...

Using simple game-theoretical models, this paper studies the role of pre-determined rules for HRM policies. We consider a model in which HRM decisions affect employees' self-images and thereby their motivation. We show that in the absence of written rules, managers are too reluctant (1) to...

A physician performs two tasks: making diagnoses and determining treatments. To reduce medical error, residents are supposed to consult their supervisors when they face uncommon circumstances. However, recent research shows that residents are reluctant to do so. This paper presents a model that...

Decisions-makers often rely on information supplied by interested parties. In practice, some parties have easier access to information than other parties. In this light, we examine whether more powerful parties have a disproportionate influence on decisions. We show that more powerful parties...

At the start of their term, politicians often announce which issue they intend to address. To shed light on this agenda setting, we develop a model in which a politician has to decide whether or not to address a public issue. Addressing an issue means that the politician investigates the issue...
