Structurally estimating the Grossman and Helpman (1994) model using coverage ratios that include non-tariff barriers leads to biased parameter estimates. We develop a quot;protection for salequot; theoretical framework consistent with the data, by explicitly allowing for non-tariff barriers....

When citizens in a poor constrained society are very unequally endowed, they are likely to find it hard to agree on reforms, even though the status quo hurts them collectively. Each citizen group or constituency prefers reforms that expand its opportunities, but in an unequal society, this will...

Although most disputes between groups of people are settled peacefully, sometimes disputes result in war. This lecture uses historical examples to illustrate how the ability to negotiate a credible peaceful settlement of a dispute between sovereign states, typically a dispute over the control of...

This paper reviews the economics approach to conflict and national borders. The paper provides a summary of ideas and concepts from the economics literature on the size of nations; illustrates them within an analytical framework where populations engage in conflict over borders and resources,...

We show that grandfathering fishing rights to local users or recognizing first possessions is more dynamically efficient than auctions of such rights. It is often argued that auctions allocate rights to the highest-valued users and thereby maximize resource rents. We counter that rents are not...

Governments fighting terrorists have many tactical options, yet these options often yield unintended and counterproductive consequences. This paper models a terrorist organization, a religious group from which the terrorists recruit suicide bombers, and the society in which the terrorists are...

We establish a theoretical as well as empirical framework to assess the role of resource endowments and their geographic location for inter-State conflict. The main predictions of the theory are that conflict tends to be more likely when at least one country has natural resources; when the...

We develop a theory of interstate conflict in which the degree of genealogical relatedness between populations has a positive effect on their conflict propensities because more closely related populations, on average, tend to interact more and develop more disputes over sets of common issues. We...
