Some committees are made up of experts, persons interested in both the (subject) matter at hand and in coming across as able decision-makers. Such committees would like to conceal disagreement from the public. We present a theory that describes the reaction of experts to the requirement to...

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...

In housing markets with asymmetric information list prices may signal unobserved properties of the house or the seller. Asymmetric information is the starting point of many models for the housing market. In this paper, we estimate the causal effect of list-price reductions to test for the...

We investigate the presence of moral hazard and advantageous or adverse selection in a market for supplementary health insurance. For this we specify and estimate dynamic models for health insurance decisions and health care utilization. Estimates of the health care utilization models indicate...
