We construct a dynamic theory of civil conflict hinging on inter-ethnic trust and trade. The model economy is inhabitated by two ethnic groups. Inter-ethnic trade requires imperfectly observed bilateral investments and one group has to form beliefs on the average propensity to trade of the other...

We study the effect of civil conflict on social capital, focusing on the experience of Uganda during the last decade. Using individual and county-level data, we document large causal effects on trust and ethnic identity of an exogenous outburst of ethnic conflicts in 2002-05. We exploit two...

We study from both a theoretical and an empirical perspective how a network of military alliances and enmities affects the intensity of a conflict. The model combines elements from network theory and from the politico-economic theory of conflict. We postulate a Tullock contest success function...

This paper studies empirically the impact of mining on conflicts in Africa. Using novel data, we combine geo-referenced information over the 1997-2010 period on the location and characteristics of violent events and mining extraction of 27 minerals. Working with a grid covering all African...

This Paper presents a macroeconomic model where firms may endogenously outsource part of their production process. We start from the premise that adaptation to uncertainty cannot be contracted upon in the worker - employer relationship. Outsourcing decisions then balance flexibility gains...

Over the past decades, the real and financial volatility of listed firms has increased, while the volatility of private firms has decreased. We first provide panel data evidence that, at the firm level, sales and employment volatility are impacted by changes in the degree of ownership...

This paper analyzes the effects of financial liberalization on growth and volatility at the industry level in a large sample of countries. We estimate the impact of liberalization on production, employment, firm entry, capital accumulation, and productivity, using both de facto and de jure...

This Paper investigates the links between the nature of contractual relationships within firms, the strength of information flows spreading between firms and the dynamics of technological competition. At the firm level, we focus on the corporate incentives to design Knowledge Management policies...

This paper analyses theoretically and empirically the relationship between trade and war. We show that the intuition that trade promotes peace is only partially true even in a model where trade is beneficial to all, war reduces trade and leaders take into account the costs of war. When war can...

This Paper shows that international trade affects the demand for skill through an export-based channel. Our working hypothesis is that the very act of exporting requires an effort of skill upgrading, in particular among occupations related to marketing and development. Using firm level data, we...
