In developing countries, informal firms (those that are not registered with the government) account for about half of all economic activity. We consider three broad views of the role of such firms in economic development. According to the romantic view, these firms would become the engine of...

We establish five facts about the informal economy in developing countries. First, it is huge, reaching about half of the total in the poorest countries. Second, it has extremely low productivity compared to the formal economy: informal firms are typically small, inefficient, and run by poorly...

Growth and structural transformation of the manufacturing sector in developing countries are generally considered to be the result of the expansion of the "modem" (large-scale) sector relative to the "traditional" (small-scale) sector. Examining the sources of labor productivity growth in...

We develop a micro-founded general equilibrium model with heterogeneous agents and three dimensions of financial inclusion: access (determined by a participation cost), depth (determined by a borrowing constraint), and intermediation efficiency (determined by a monitoring cost). We find that the...

The lack of reliable electricity in the developing world is widely viewed by policymakers as a major constraint on firm productivity. Yet most empirical studies find modest short-run effects of power outages on firm performance. This paper builds a dynamic macroeconomic model to study the...

The Argentine economy was transformed in the late nineteenth century by the mass migration of millions of Europeans. Various ideas have surfaced concerning the likely impact of this labor inflow: that it favored the wheat revolution on the pampas; that it promoted urbanization and the rapid...
