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...

Selecting an estimator for the variance covariance matrix is an important step in hypothesis testing. From less robust to more robust, the available choices include: Eicker/White heteroskedasticity-robust standard errors, Newey and West heteroskedasticity-and-autocorrelation- robust standard...

This paper presents a new method for estimating social interaction effects. The proposed approach is based on using network interaction structure induced variation in equilibrium influence to construct conditionally balanced interaction structures. As equilibrium influence is determined by the...

It is well known that pooled insurance coverage can induce a form of ex-ante moral hazard: people make inefficiently low investments in self-protective activities. This paper identifies another ex-ante moral hazard that runs in the opposite direction: it causes people to choose inefficiently...

Scientific research and private-sector technological innovation are different in terms of objectives, constraints, and organizational forms. For example, the for-profit objective that drives private-sector innovation is absent from much of scientific research, and individual researchers have...

We develop a two-country general equilibrium model of foreign assistance tied to environmental clean-up in the presence of transboundary pollution. The recipient country generates pollution as a by-product in the production of a ‘dirty’ good, which it consumes as well as exports to the donor...

A market share exclusion contract between a seller and a buyer prevents rival sellers from competing for a share of the buyer's purchases. For non-discriminatory contracting we show that, unlike exclusion through exclusive dealing, market share exclusion can be profitable even when buyers...

The optimal management of a non-renewable resource extraction project is studied when input and output prices follow correlated stochastic processes. The decision problem is specified by two Bellman equations describing the project when it is currently operating or mothballed. Solutions are...

There exists a large literature on the optimal deterrence of crime. Within the literature, however, there exists a controversy over what the appropriate criterion to determine optimality should be. While the most popular method is that of maximization of a utilitarian welfare function, another...

In Nash equilibrium, agents are autarchic in their optimization protocol, whereas in Kantian equilibrium, they optimize in an interdependent way. Typically, researchers into the evolution of homo economicus treat preferences as being determined by selective adaptation, but hold fixed the...
