We explore the effect of historical ethnic borders on contemporary conflict in Africa. We document that both the intensive and extensive margins of contemporary conflict are higher close to historical ethnic borders. Exploiting variations across artificial regions within an ethnicity's...

This paper empirically tests the hypothesis that trade can act as an engine of growth using panel data for the Southern African Development Community (SADC), a regional integration agreement (RIA) organization, the central objective of whose formation was the need to accelerate, foster, and...

This paper investigates the long-term consequences of mass refugee inflow on economic development by examining the effect of the first large-scale population resettlement in modern history. After the Greco-Turkish war of 1919–1922, 1.2 million Greek Orthodox were forcibly resettled from Turkey...

Fixed-term contract employment has increasingly replaced regular open-ended employment as the predominant form of employment notably in developing countries. Guided by factory-level evidence showing nuanced patterns of co-movements of regular and contract wages, we propose a two-tiered task...

This research explores the historical roots of the division of labor in pre-modern societies. It advances the hypothesis and establishes empirically that intra-ethnic diversity had a positive effect on the division of labor across ethnicities in the pre-modern era. Exploiting a variety of...

Using Integrated Household Survey data from Georgia, we measure the observable and discriminatory ethnic wage gap, among male and female workers, and the gender wage gap, among Georgians and non-Georgians. The gender wage discrimination is larger than the ethnic wage discrimination. In the...

In developing countries with weak institutions, there is implicitly a large reliance on elections to instill norms of accountability and reduce corruption. In this paper we show that electoral discipline may be ineffective in reducing corruption when political competition is too high or too low....

This research explores the economic causes and consequences of language structures. It advances the hypothesis and establishes empirically that variations in pre-industrial geographical characteristics that were conducive to higher return to agricultural investment, larger gender gap in...

Exploiting a novel geo-referenced data set of population diversity across ethnic groups, this research advances the hypothesis and empirically establishes that variation in population diversity across human societies, as determined in the course of the exodus of humans from Africa tens of...

This paper provides a long-term view by studying the effect of the underground or shadow economy on economic growth in the Unites States over the period 1870 to 2014. Shadow activities might spur or retard economic growth depending on their interactions with the formal sector and impacts on the...
