The evolution of inequality in permanent income is investigated during the course of a less developed country's transformation from a primarily agricultural to a primarily urban-industrial economy. The source of inequality is market luck in obtaining employment in the protected urban "formal...

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...

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...

During the Great Depression, as today, migrants were accused of taking jobs and crowding relief rolls. At the time, protest concerned internal migrants rather than the foreign born. We investigate the effect of net migration on local labor markets, instrumenting for migrant flows to a...

This paper uses 1990 Census data to study the effects of immigrant inflows on the labor market opportunities of natives and older immigrants. I divide new immigrants, older immigrants, and natives into distinct skill groups and focus on skill-group-specific outcomes within cities. An important...

In this paper we explore the effects of labor demand shifts and population adjustments across metropolitan areas on the employment and earnings of various demographic groups during the 1980s. Results show that, although earnings and employment deteriorated for less-education and black males in...

Recent studies of late nineteenth century labor market integration have found that despite high rates of geographic mobility relatively large inter- and intra-regional differentials in real wages persisted with little tendency toward convergence. These results point to the absence of a unified...

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...

Tracking individual workers across jobs after Brazil's trade liberalization in the 1990s shows that tariff cuts trigger worker displacements, but neither exporters nor comparative-advantage sectors absorb trade-displaced labor. On the contrary, exporters separate from significantly more and hire...

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...
