We analyse a simple model of dynamic moral hazard in which there is a clear and tractable trade-off; between static and dynamic incentives. In our model, a principal wants an agent to complete a project. The agent undertakes unobservable effort, which affects in each period the probability that...

We propose a simple model of optimal stopping where the economic environment changes as a result of learning. A primary application of our framework is an optimal job search problem when the worker's labour market opportunities are initially uncertain. We distinguish between two interpretations...

This Paper examines irreversible investment in a project with uncertain returns, when there is an advantage to being the first to invest, and externalities to investing when others also do so. Pre-emption decreases and may even eliminate the option values created by irreversibility and...

This Paper considers the 'failing firm defence'. Under this principle, found in most antitrust jurisdictions, a merger that would otherwise be blocked due to its adverse effect on competition is permitted when the firm to be acquired is a failing firm, and an alternative, less detrimental merger...

Empirical studies have found that takeover activity is positively related to the absolute size of industry-level shocks. In this paper we develop a dynamic framework to analyze the timing of takeover which explains this pattern. Takeover may create value either by exploiting synergies or through...

This Paper provides a sufficient condition for the existence and uniqueness of equilibrium in monotone pure strategies, in games of incomplete information. First, we show that if each player's incremental ex post pay-off is uniformly increasing in its own action and type, and its type is...
