We study how opening to trade affects economic growth in a model where heterogeneous firms can adopt new technologies already use by other their home country. characterize the rate using summary statistic of profit distribution: mean-min ratio. Opening increases spread through increased export opportunities and foreign competition, induces more rapid technology adoption, generates faster growth...

This paper quantifies the contribution of technology gaps to international income inequality. I develop an endogenous growth model where cross-country differences in R&D efficiency and cross-industry innovation adoption opportunities together determine equilibrium gaps, trade patterns, Countries with higher are richer have comparative advantage more innovation-dependent industries. calibrat...

We develop a general equilibrium business cycle model with imperfectly observed neutral and investment-specific technology shocks. The model response to neutral technology shocks is similar to the response in an environment with perfect information. However the response to an investmentspecific shock is more persistent and depends on the distance between agent expectations and actual values at ...

Using firm-level data for three Sub-Saharan African (SSA) countries and four manufacturing industries, I examine how imports from OECD countries lead to productivity gains for domestic establishments through their knowledge absorption capabilities. I find that domestic firms with technology standards farther away from the international frontier benefit more from trade than those with technology...

This paper develops a simple network model to describe the dynamic of the intensive and extensive margin of international trade flows. The result is achieved by means of the combination of two mechanisms of proportional growth: the first (discrete) determines the formation of trade links, the second (continuous) governs trade intensity. We show that our setup is able to simultaneously match a l...
