This paper theoretically investigates how labor-market tightness affects market outcomes if firms use informal and self-enforcing agreements to motivate workers. We characterize profit-maximizing equilibria and derive the following results. First, an increase in the supply of homogenous workers...

This paper investigates how labor-market tightness affects market outcomes if firms use informal, self-enforcing, agreements to motivate workers. We characterize profit-maximizing equilibria and show that an increase in the supply of homogenous workers can increase wages. Moreover, even though...

We develop models of markets with procrastinating consumers where competition operates - or is supposed to operate - both through the initial selection of providers and through the possibility of switching providers. As in other work, consumers fail to switch to better options after signing up...

We study a model of task completion with the opportunity to learn about own self-control problems over time. While the agent is initially uncertain about her future self-control, in each period she can choose to learn about it by paying a non-negative learning cost and spending one period. If...

This paper theoretically investigates how an increase in the supply of homogenous workers can raise wages, generating new insights on potential drivers for the observed non-negative wage effects of immigration. We develop a model of a labor market with frictions in which firms can motivate...

Recent studies investigate policies motivating consumers to make an active choice as a way to protect unsophisticated consumers. We analyse the optimal timing of such choice-enhancing policies when a firm can strategically react to them. In our model, a firm provides an automatic enrolment or...

We analyze a simple task-assignment model in which a principal assigns a task to one of two agents depending on the state. If the agents have standard concave utility, the principal assigns the task to an agent with the highest productivity in each state. In contrast, if the agents are loss...

We investigate moral-hazard problems with limited liability where agents have expectation-based reference-dependent preferences. We show that stochastic compensation for low performance can be optimal. Because of loss aversion, the agents have first-order risk aversion to wage uncertainty. This...
