Conventional wisdom in economic history suggests that conflict between countries can be enormously disruptive of economic activity, especially international trade. Yet nothing is known empirically about these effects in large samples. We study the effects of war on bilateral trade for almost all...

This article reviews the recent burgeoning political economics research on nation-building. We focus on three main aspects of this body of work. First, we discuss methodological issues related to measuring nation-building outcomes and provide a synthesis of studies that employ different...

European empires had two key economic aspects: the extraction of colonial wealth by colonizers, and the relevance of trade for the colonial economies. I build a simple model of decolonization that puts these two elements at centre stage. By controlling policy in the colony, the mother country...

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

Using a new, global data base covering the years 1950 to 2015, we study the impact of sanctions on international trade and welfare. We make use of the rich dimensionality of our data and of the latest developments in the structural gravity literature. Starting with a broad evaluation by sanction...

Capitalizing on the latest developments in the gravity literature, we utilize two new datasets on sanctions and trade to study the impact of economic sanctions on international trade in the mining sector, which includes oil and natural gas. We demonstrate that the gravity equation is well suited...

The new update of the GSDB contains a total of...

The fact that crossing a political border dramatically reduces trade flows has been widely documented in the literature. The increasing number of borders has surprisingly attracted much less attention. The number of independent countries has indeed risen from 72 in 1948 to 192 today. This paper...
