This paper evaluates the global welfare impact of China's trade integration and technological change in a quantitative Ricardian-Heckscher-Ohlin model implemented on 75 countries. We simulate two alternative productivity growth scenarios: a "balanced" one in which China's productivity grows at...

We estimate productivities at the sector level for 72 countries and 5 decades, and examine how they evolve over time in both developed and developing countries. In both country groups, comparative advantage has become weaker: productivity grew systematically faster in sectors that were initially...

This paper addresses the lack of connection between theory and empirics in most export diversification - economic development studies. We provide a Ricardian-based theoretical explanation of countries' relative export variety as a function of the level of technology and country size assessed...

This paper studies the origins and consequences of international technology gaps. I develop an endogenous growth model where R&D efficiency varies across countries and productivity differences emerge from firm-level technology investments. The theory characterizes how innovation and learning...

The closed economy neoclassical model predicts lung-run convergence in per-capita income. We show, within a neoclassical framework, that international trade among two countries differing only in their initial capital endowment generates long-run income differences. Our results suggests that...

We offer a duality-based methodology for incorporating multi-sector effects of international trade into open economy macroeconomic models, developing the concepts of the dynamic factor price equalization set and the integrated intertemporal equilibrium. Under this approach, the aggregate...

This work shows the asymmetric effect of the reduction in transportation costs across different sectors in the process of the Great Divergence. Specifically, the analysis indicates that reductions in transportation costs of industrial goods enhance convergence of the growth rates of trading...

The paper shows that the relationship between GDP per capita and levels of specialization can be predicted differently depending on whether the intensive or the extensive margin is considered. It shows that at the extensive margin countries continuously diversify their exports and that...
