Holmstrom (1982) considered a group of agents who jointly produce some output and showed that if the agents are required to balance the budget then the first best, or Pareto efficient, allocation cannot be obtained as an equilbrium relative to any sharing rule. Recent research on risk-neutral...

We analyse the production of knowledge in research teams. Individuals put in effort, which is not enforcable. Effort increases the probability of a successful outcome. Research with enforcable effort displays increasing returns to scale; these scale economies are limited, or even reversed, by the...

We evaluate the impact of real business cycle shocks on corruption and economic policy in a model of entry regulation in a representative democracy. We .nd that corruption is procyclical and regulation policy is counter-cyclical. Corrupt politicians engage in excessive stabilization of aggregate...

We study the joint determination of corruption and economic growth. Our model can generate multiple equilibria when complementarity between corruption and growth is sufficiently strong. Our estimates of the impact of corruption on growth take into account that corruption is endogenous and that...
