This paper applies recent advances in the study of labor market dynamics to a representative developing country with a large informal or unregulated sector, Mexico. It studies quarterly gross flows of workers over a 15-year period that includes two recoveries and recessions, including the celebrated 1995 Tequila crisis. It finds, first, that the formal or modern salaried sector shows the same procyclical job finding rate and mildly countercyclical separation behavior identified in the recent U.S. literature, and relative wage rigidity, both consistent with Shimer (2005a) and Hall (2005). The unregulated informal sector, however, shows reasonable acyclicality in the job finding rate coupled with sharp countercyclical movements in the job separation rate, consistent with standard small firm dynamics and Davis and Haltiwanger (1992 and 1999). This interaction of regulatory coverage and firm sizes, and patterns of gross worker flows thus sheds suggestive light on the roots of countercyclical job finding behavior in the U.S. literature. Second, the patterns of worker transitions between formality and informality correspond to the job-to-job dynamics observed in the United States and not to the traditional idea of informality constituting the inferior sector of a segmented market. That said, the countercyclical job finding in the formal sector combined with the acyclical job finding in informality does lead to the latter absorbing relatively more labor during downturns. Third, aggregate employment dynamics vary across the Tequila crisis and the later 2001 slowdown, suggesting that not only the composition of employment, but the nature of the shocks is important to understanding how the labor market adjusts.

Analyzes informality in Latin America, exploring root causes and reasons for and implications of its growth. This book uses two distinct but complementary lenses. It concludes that reducing informality levels and overcoming the "culture of informality" will require actions to increase aggregate productivity in the economy.

Abstract: This paper studies gross worker flows to explain the rising informality in Brazilian metropolitan labor markets from 1983 to 2002. This period covers two economic cycles, several stabilization plans, a far-reaching trade liberalization, and changes in labor legislation through the Constitutional reform of 1988. First, focusing on cyclical patterns, the authors confirm that for Brazil, the patterns of worker transitions between formality and informality correspond primarily to the job-to-job dynamics observed in the United States, and not to the traditional idea of the informal queuing for jobs in a segmented market. However, the analysis also confirms distinct cyclical patterns of job finding and separation rates that lead to the informal sector absorbing more labor during downturns. Second, focusing on secular movements in gross flows and the volatility of flows, the paper finds the rise in informality to be driven primarily by a reduction in job finding rates in the formal sector. A small fraction of this is driven by trade liberalization, and the remainder seems driven by rising labor costs and reduced flexibility arising from Constitutional reform.

This paper applies recent advances in the study of labor market dynamics to a representative developing country with a large informal or unregulated sector, Mexico. It studies quarterly gross flows of workers over a 15-year period that includes two recoveries and recessions, including the celebrated 1995 Tequila crisis. It finds, first, that the formal or modern salaried sector shows the same procyclical job finding rate and mildly countercyclical separation behavior identified in the recent U.S. literature, and relative wage rigidity, both consistent with Shimer (2005a) and Hall (2005). The unregulated informal sector, however, shows reasonable acyclicality in the job finding rate coupled with sharp countercyclical movements in the job separation rate, consistent with standard small firm dynamics and Davis and Haltiwanger (1992 and 1999). This interaction of regulatory coverage and firm sizes, and patterns of gross worker flows thus sheds suggestive light on the roots of countercyclical job finding behavior in the U.S. literature. Second, the patterns of worker transitions between formality and informality correspond to the job-to-job dynamics observed in the United States and not to the traditional idea of informality constituting the inferior sector of a segmented market. That said, the countercyclical job finding in the formal sector combined with the acyclical job finding in informality does lead to the latter absorbing relatively more labor during downturns.

The analysis in this report confirms the findings of previous studies that trade liberalization improves aggregate welfare and is in the long run associated with higher employment and wages. The analysis addresses a major gap in the literature, which has heretofore provided limited evidence about the trade-related adjustment costs faced by workers in developing countries and how they are affected by mobility costs. Labor market frictions reduce the potential gains from trade reform. For a tariff reduction in a given sector, the resulting change in relative prices raises real wages in some sectors and reduces them in the liberalized sector. The emerging wage gaps lead to labor reallocation. But workers typically incur costs to change jobs; the higher the mobility costs, the slower the transition to the new labor market steady state. Workers’ sticky feet result in foregone welfare gains from trade. This report presents an estimation strategy for capturing mobility costs when only net flows of workers between industries are observed, generating cross-country estimates for 47 developed and developing countries. The basic analytical approach is then refined to take advantage of micro-level data on worker transitions and wages when gross flows can be observed to derive mobility cost estimates that account for sector and formality status. These cost estimates are used to model the dynamic paths of labor reallocation between sectors and in and out of the labor force, the associated wage paths, and the resulting labor adjustment costs. The main findings of the report are that: labor mobility costs in developing countries are high; foregone trade gains due to frictions in labor mobility can also be substantial; workers bear the brunt of adjustment costs; mobility costs and labor market adjustments to trade-related shocks vary by industry, firm type, and worker type; entry costs are significantly higher for formal than for informal employment; trade reforms increase economy-wide wages and employment; and workers displaced by plant closings are likely to face relatively long adjustment periods. The findings provide insights that could be helpful to policymakers hoping to mitigate negative short-term consequences of trade liberalization and facilitate labor adjustment.

There is one asset that poor people have in abundance: labor. Thus, what distinguishes the poor from the non-poor in low income countries is, simply, their ability to sell labor at a good price. It should be of little surprise, then, that enhancing the poor's access to employment is increasingly recognized as key to development. But while the creation of "good" jobs for the poor has become a policy priority for many developing countries, the mechanisms by which employment stimulates growth and reduces poverty have, until now, not been well understood. This book aims to help fill that.
