Firm heterogeneity is mostly discussed in the literature from the viewpoint of productivity differential. In contrast this paper recognizes wealth heterogeneity as an important factor that results in firm heterogeneity. The issue of wealth heterogeneity and export incentive through credit market...

Traditional gravity models posit an inverse relationship between geographical distance and bilateral trade due to increased transportation costs. However, recent literature suggests that bilateral service trade may increase between two countries located at an appropriate geographical distance....

We combine original geo-referenced data on mining extraction of 15 minerals with information on conflict events at spatial resolution of 0.5o x 0.5o for all Africa over 1997-2010. Exploiting exogenous variations in world prices, we find a positive impact of mining on conict at the local level....

This paper uses detailed information on the latitude and longitude of conflict events in Sub-Saharan African countries to study the impact of external income shocks on the likelihood of violence. We consider a number of external demand shocks faced by the countries or the regions within...

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...

Using a French firm-level database that combines balance-sheet and product-destination-specific export information over the period 1995-2001, we study the interconnections between exports and domestic sales. We identify exogenous shocks that affect the firms' demand on foreign markets to...

This paper explores the possibility of international technology transfer in lieu of trade in a model with absolute and comparative advantage. Countries having absolute advantage in producing a good may offer that technology to a possible trading partner against a fee and both the countries might...

This paper explores the role of wage fund as the basic source of credit, capital or finance in a dynamic Ricardian model, which consists of three classes of agents: the workers, the capitalist, and the producers of goods. We introduce and develop an elaborate dynamic wage fund model in the...

In this paper we revisit the influential theory of monopolistic competition and optimum product variety as developed by Dixit and Stiglitz (1977) with applications in international trade by Krugman (1979,1980), by modeling fixed and variable costs of production in terms of underlying use of...
