How do foreign interests influence the policy determination process? What are the welfare implications of such foreign influence? In this paper we develop a model of foreign influence and apply it to the study of optimal tariffs. We develop a two-country voting model of electoral competition,...

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...

This paper analyzes empirically the relationship between civil wars and international trade. We first show that trade destruction due to civil wars is very large and persistent and increases with the severity of the conflict. We then test the presence of two effects that trade can have on the...

A study of distortions to agricultural incentives in 18 developing countries during 1960-84, by Krueger, Schiff and Valdés (1988; 1991), found that policies in most of those developing countries were directly or indirectly harming their farmers. Since the mid-1980s there has been a substantial...

Using data collected by the International Institute of Agriculture, we document the disintegration of international commodity markets between 1913 and 1938. There was dramatic disintegration during World War I, gradual reintegration during the 1920s, and then a very substantial disintegration...

Drawing upon a comprehensive database of contemporary protectionism, this paper offers an initial assessment of the extent to which our understanding of protectionism may have to evolve. While some long-standing features of protectionism appear to have endured (such as the distribution of...

The Doha multilateral round of trade negotiations sponsored by the WTO has been dragging on for over a decade, with no end in sight. In this short paper we assess empirically what determines the duration of trade negotiations, focusing on the span between the start of trade talks and their...

In 2009, the United States imposed additional tariffs for a three-year period on imports of automotive tires from China under a special-safeguard provision included in China’s Protocol of Accession to the WTO. China challenged the measure in the WTO. The case marked the first WTO dispute in...

During the last three decades, the stock of government debt has increased in most developed countries. During the same period, we also observe a significant liberalization of international financial markets and an increase in income inequality in several industrialized countries. In this paper...

What are the main causes of international terrorism? The lessons from the surge of academic research that followed 9/11 remain elusive. The careful investigation of the relative roles of economic and political conditions did little to change the fact that existing econometric estimates diverge...
