In standard models of experimentation, the costs of project development consist of (i) the direct cost of running trials as well as (ii) the implicit opportunity cost of leaving alternative projects idle. Another natural type of experimentation cost, the cost of holding on to the option of...

This paper studies the Markov perfect equilibrium outcomes of a dynamic game of electoral competition between two policy-motivated parties. I model incumbent policy persistence: parties commit to implement a policy for their full tenure in office, and hence in any election only the opposition...

Electoral systems promote strategic voting and aect party systems. Duverger (1951) proposed that plurality rule leads to bi-partyism and proportional representation leads to multi-partyism. We show that in a dynamic setting, these static eects also lead to a higher option value for existing...

This paper studies the symmetric equilibria of a two-buyer, two-seller model of directed search in which sellers commit to information provision. More informed buyers have better differentiated private valuations and extract higher rents from trade. When sellers cannot commit to sale mechanisms,...

I model the dynamic agency relationship underlying prevention. In each period, a principal can transfer resources to an agent that has private information about a problem, which the agent can direct to solving the problem or divert into rents. Problems are persistent and rectifiable: they...

Regulation is a set of constraints imposed on transactions between buyers and sellers. We introduce a dynamic frictional matching model with horizontal differentiation and nontransferable utility in which a regulator determines permissible transactions. We show the existence and uniqueness of a...

This paper studies the competition between sellers who choose how much information to provide to potential buyers. We analyse the symmetric equilibria in information provision of a game in which two sellers with unit supplies compete to attract two buyers with unit demands. Sellers compete ex...
