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...

"es.Using an industry-level dataset of production and trade spanning 75 countries and 5 decades, and a fully specified multi-sector Ricardian model, we estimate productivities at the sector level and examine how they evolve over time in both developed and developing countries. We find that in...

This paper studies the cross-country patterns of risky innovation and growth through the lens of international trade. It uses a simple theoretical framework of risky quality upgrading by firms under varying levels of financial development to derive two predictions. First, the mean rate of...
