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...

It is often argued that informal labor markets in developing countries promote growth by reducing the impact of regulation. On the other hand informality may reduce the amount of social protection offered to workers. We extend the wage-posting framework of Burdett and Mortensen (1998) to allow...

Informal payments are a frequently overlooked source of local public finance in developing countries. We use microdata from ten countries to establish stylized facts on the magnitude, form, and distributional implications of this "informal taxation." Informal taxation is widespread, particularly...

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 article reviews the recent literature in economics on small-scale entrepreneurship ("microentrepreneurship") in low-income countries. Major themes in the literature include the determinants and consequences of joining the formal sector; the impacts of access to credit and other financial...

Standard measures of poverty may reveal nothing about whether the poorest of the poor are being lifted-up or left-behind, yet this is a widespread concern among policy makers and citizens. The paper assesses whether public spending on social protection benefits the poorest and hence lifts the...

This essay reviews what economists have learned about the impact of labor market institutions, defined broadly as government regulations and union activity on labor outcomes in developing countries. It finds that: 1) Labor institutions vary greatly among developing countries but less than they...

Progressively targeted cash transfers remain the dominant policy response to chronic poverty in developing countries. But are there alternative social protection policies that might have larger poverty impacts over time for the same public expenditure? To explore this question, this paper...

This paper discusses the problems facing the Mexican economy. It operates under a heavy burden of monopoly and regulation. We focus on two issues that should receive more attention in discussions of Mexican policy. (1) The family is under stress in Mexico and this retards the growth of skills of...

We conduct a field experiment in Sri Lanka providing informal firms incentives to formalize. Information about the registration process and reimbursement of direct costs has no effect. Payments equivalent to one-half to one month (alternatively, 2 months) of the median firm's profits leads to...
