Principal-agent models are pervasive in theoretical and applied economics, but their analysis has largely been limited to the ``first-order approach'' (FOA) where incentive compatibility is replaced by a first-order condition. This paper presents a new approach to solving a wide class of...

Should contract design induce an agent to conduct a precontractual investigation even though, in any case, the agent will become fully informed after the signing of the contract? This paper shows that imperfect investigations might be encouraged. The result stands in contrast to previous...

The notion that foreign aid harms the institutions of recipient governments remains prevalent. We combine new disaggregated aid data and various metrics of political institutions to re-examine this relationship. Long-run cross-section and alternative dynamic panel estimators show a small...

Foreign aid’s effectiveness in promoting economic growth remains mired in controversy.We examine the impact of the volatility of aid on economic growth, controlling for the level of aid. A four-year panel analysis is conducted encompassing 155 countries over the period 1966-2001. We find that...

The vast majority of the books and articles that have been written over the past few centuries about trade policy in general and protectionism in particular have been written from a utilitarian perspective. Indeed, it would only be a slight overstatement to say that the only works written about...

Policy reforms are often multifaceted. In the rent-seeking literature policies are usually taken as one-dimensional. This paper models policy formation using a political contest with endogenous policy proposals containing two dimensions. The two dimensions provide an opportunity to trade off one...

We introduce career concerns into rank-order tournaments and offer a novel explanation for the pervasiveness of multiple prizes. We argue that career-concerned individuals, already facing market pressure to perform, will be reluctant to participate in winner-take-all competitions. To entice them...

When a principal’s monitoring information is private (non-verifiable), the agent should be concerned that the principal could misrepresent the information to reduce the agent’s wage or collect a monetary penalty. Restoring credibility may lead to an extreme waste of resources - the so-called...

How can a principal (employer or voter) induce an agent (worker or politician) to choose the 'right' actions if risky actions reveal the agent's decision-making competence and only dismissal can be used as an incentive instrument? The principal wishes to replace incompetent agents, but...
