We consider a principal-agent model, where a single agent exhibits problems of self control modelled using Gul, Pesendorfer (2001) type temptation preferences. For a general class of preferences, yet specific family of temptation utilities, we characterize an optimal contract in such a setting...

We extend Akerlof's (1970) "Market for Lemons" by assuming that some buyers are overconfident. Buyers in our model receive a noisy signal about the quality of the good that is at display for sale. Overconfident buyers do not update according to Bayes' rule but take the noisy signal at face...

As we have demonstrated in a recent laboratory experiment [see Sebald and Walzl (2012)], individuals tend to sanction others who subjectively evaluate their performance whenever this assessment falls short of the individual's self-evaluation even if their earnings are unaffected by the...

We conduct a laboratory experiment with agents working on and principals benefitting from a real effort task in which the agents' performance can only be evaluated subjectively. Principals give subjective performance feedback to agents and agents have an opportunity to sanction principals. In...

This paper provides an economic rationale for overachieving behavior in non-professional activities in the labour market. The intrinsically motivated worker uses his achievement in the non-professional activity to signal his work ethic. When the worker‘s career concern is weak, he exerts no...

Firms strategically disclose product information in order to attract consumers, butrecipients often find it costly to process all of it, especially when products have complexfeatures. We study a model of competitive information disclosure by two senders, inwhich the receiver may garble each...

Does being lucky (or unlucky) affect honest decision-making? We examine (1) whether luck-based income strengthens or erodes the moral value of honesty; (2) whether the perceived level of agency over an uncertain event affects the relationship between luck and honesty; and (3) whether accumulated...
