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...

This paper addresses policies aimed at closing the rural-urban gap for one of the Millennium Development Goals (MDGs), the under-five mortality rate (U5MR). The paper relies on the Maquette for MDG Simulations (MAMS), a computable general equilibrium model, applied to the database of an...

Empirical evidence indicates that in many developing regions, the extreme poor in more marginal land areas form a "residual" pool of rural labor. Structural transformation in such developing economies depends crucially on labor and land use decisions of these most-vulnerable populations located...

Despite sustained output growth since 1997, low-income Commonwealth of Independent States (CIS) countries (CIS-7) have not experienced growth in employment, a phenomenon observed elsewhere in transitional economies and labeled as "jobless growth." The author addresses the causes of this...

This paper investigates the determinants of informal economic activity. We present two equilibrium models of informality and test their implications using a survey of 48,000+ small firms in Brazil. We define informality as tax avoidance; firms in the informal sector avoid tax payments but suffer...

The authors evaluate the impact of two key factor market distortions in China on rural-urban inequality and income distribution. They find that creation of a fully functioning land market has a significant impact on rural-urban inequality. This reform permits agricultural households to focus...
