We develop an equilibrium directed search model of the labor market where workers can simultaneously apply for multiple jobs. The main result is that all equilibria exhibit wage dispersion despite the fact that workers and firms are homogeneous. Wage dispersion is driven by the simultaneity of...

Dictatorship is the predominant political system in many developing countries. However, different dictators act quite differently: a good dictator implements growth-enhancing economic policies, e.g. investment in public education and infrastructure, whereas a bad dictator expropriates wealth of...

Consider an employer who wants her employee to work hard. As is well known from the e.ciency wage literature, the employer must pay the (wealth-constrained) employee a positive rent to provide incentives for exerting unobservable e.ort. Alternatively, the employer could make effort observable by...

Recent work in the field of mechanism design has led some researchers to propose institutional changes that would permit parties to enter into nonmodifiable contracts, which is not possible under current contract law. This paper demonstrates that it may well be socially desirable not to enforce...

We use an experiment to explore how subjects learn to play against computers which are programmed to follow one of a number of standard learning algorithms. The learning theories are (unbeknown to subjects) a best response process, fictitious play, imitation, reinforcement learning, and a trial...

We analyze innovation race in a moral hazard setting. We develop a model in which two competing entrepreneurs work independently on the same project. The entrepreneurs do not possess any wealth of their own and their research is financed by a venture capitalist. The project, if successful,...

Empirical evidence on the relationship between a country?s wealth inequality and economic growth is ambiguous. This paper provides reasonable explanations of this ambiguity. We investigate the implications which the shape of wealth distribution has for economic growth in a framework combining...

In this paper, I compare two-part tariff competition to linear pricing in a vertically differentiated duopoly. Consumers have identical tastes for quality but differ in their preferences for quantity. The main finding is that quality differentiation occurs in equilibrium if and only if two-part...

everal empirical findings have challenged the traditional trade-off between risk and incentives. By combining risk aversion and limited liability in a standard principal-agent model the empirical puzzle on the positive relationship between risk and incentives can be explained.
