The theory of large-scale entry into an industry is made complicated by its game-theoretic aspects. Even in the simplest case of one established firm facing one prospective entrant, there are some subtle strategic interactions. The established firm's pre-entry decisions can influence the...

This paper provides a review of the contradictions and conflicts in the literature on economic governance and sketches an approach to use some of the conceptual and empirical findings from that literature for development policy. The literature offers conflicting conclusions on big questions:...

The paper begins with a brief overview of the theory of incentives, with special attention to issues that are important in the public sector, in general and human capital in particular. It then reviews some case studies and empirical studies of incentives in the public sector, examining how...

Many recent stochastic dynamic models in economics and finance are based on the theory of Brownian motion and its control or regulation. A heuristic exposition of this theory is presented with emphasis given to Itô's Lemma, the calculation of expected values and the derivation of Smooth Pasting...

Decisions made under ongoing uncertainty and costly reversibility entail a range of the state variable where inaction is optimal, which in turn produces hysteresis--permanent effects of temporary shifts. The range is usually defined by nonlinear equations that need numerical solutions. In this...

We extend the theory of common agency to the situation where the principals' payoffs are affected by their "ex ante" expectations of the agent's "ex post" choice. We show how the usual truthful schedules must be modified to account for the rational expectations constraint. We apply the model to...
