This work analyzes the impact of regulation policies in two distinct settings. Chapter 1 provides an overview of the existing theoretical literature on innovation and entrepreneurship. It summarizes some of the main findings of the effect of various means of protecting intellectual property on...

We characterize equilibria of games with two properties: (i) Agents have the opportunity to adjust their strategic variable after their initial choices and before payoffs occur; but (ii) they can only add to their initial amounts. The equilibrium set consists of just the Cournot-Nash outcome,...

This paper examines the use of switching costs by long lived strategic buyers to manage dynamic competition between rival suppliers. The analysis reveals how buyers may employ switching costs to their advantage. We show, ironically, when switching costs are high a buyer may induce suppliers to...

We present a theory of strategic voting that predicts elections are more likely to be close and voter turnout is more likely to be high when citizens possess better public information about the composition of the electorate. These findings are disturbing because they suggest that providing more...

This paper studies a sequential bargaining model in which, as in the rent-seeking literature, agents expend resources to be the proposer, and agreement requires affirmative votes of either all agents or a subset of them. By focusing on the Stationary Subgame Perfect Equilibrium, it is found that...

A well-known shortcoming of rational voter models is that the equilibrium probability that an individual votes converges to zero as the population of citizens tends to infinity. We show that this does not ñ as is often suggested ñ imply that equilibrium voter turnout is insignificant in the...
