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...

The documented link between natural resources and civil conflict is not well understood. This paper uses a political economy framework to explore the emergence of resource-based civil conflict driven by group-level discontent. Previous models of resource conflicts are premised on the idea that...

The link between natural resource dependence and internal conflict has been approached from a variety of angles in a large and growing interdisciplinary literature. While there is an expanding consensus as to what matters the most for such intra-state violence episodes, the feasibility -...

This paper extends the generalized empirical likelihood method to the case in which the moment conditions are defined on a continuum (CGEL). We show, for the iid case, that CGEL is asymptotically equivalent at the first order to the generalized method of moments for a continuum (CGMM) developed...

To comply with laws, regulations and social demands, polluting firms increasingly purchase the needed means from specialized suppliers. This paper an- alyzes this relatively recent phenomenon. We show how environmental regulation, the size of the output market, the elasticity of demand for...

A leading explanation of long run U.S. inflation trends attributes both the fall of inflation in the 1980s and the subsequent years of low and stable inflation to well run monetary policy pinning down inflationary expectations. Most other OECD economies experienced a similar rise and fall 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...

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...
