This paper analyzes the cyclical properties of worker flows in Brazil and Mexico, two important developing countries with large unregulated or informal sectors. It generates three stylized facts that are critical to the accurate modeling of the sector and which suggest the need to rethink the approaches to date. First, the unemployment rate is countercyclical essentially because job separations of informal workers increase dramatically in recessions. Second, the share of formal employment is countercyclical because of the difficulty of finding formal jobs from inactivity, unemployment and other informal jobs during recessions rather than because of increased separation from formal jobs. Third, flows from formality into informality are not countercyclical, but, if anything, pro-cyclical. Together, these challenge the conventional wisdom that has guided the modeling the sector that informal workers are primarily those rationed out of the formal labor market. They also offer a new synthesis of the mechanics of the cyclical adjustment process. Finally, the paper offers estimates of the moments of worker flows series that are needed for calibration.

A large percentage of workers and firms operate in the informal economy, outside the line of sight of governments in emerging market and developing economies. This may hold back the recovery in these economies from the deep recessions caused by the COVID-19 pandemic--unless governments adopt a broad set of policies to address the challenges of widespread informality. This study is the first comprehensive analysis of the extent of informality and its implications for a durable economic recovery and for long-term development. It finds that pervasive informality is associated with significantly weaker economic outcomes--including lower government resources to combat recessions, lower per capita incomes, greater poverty, less financial development, and weaker investment and productivity.

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.

Abstract: The authors study the dynamics of three developing country labor markets using recent advances in the estimation of continuous time Markov processes. They first examine the flows of workers among five states: three types of paid labor, unemployment, and out of the labor force. The authors find a high degree of commonality in patterns of worker flows among the three countries and attempt to compare the flexibility of the markets by examining an index of overall mobility. Second, they seek to establish whether the issues of advanced country labor markets apply to developing country markets or whether the latter constitute a different phylum. Paralleling the mainstream literature on the role of being out of the labor force as discouraged unemployment, the authors then identify some common stylized facts about the role of the informal self-employed and salaried sectors and to what degree they serve as a holding pattern versus a desirable alternative to formal sector work. In the process, the authors identify very strong differences in mobility patterns between men and women and attempt to shed some light on whether these differences arise from discrimination or perhaps instead the constraints imposed by household responsibilities. Finally, they study labor market adjustment across the business cycle in Mexico and identify patterns of job creation and destruction among the three paid sectors and confirm the mainstream view of the role of out of the labor force as a procyclical phenomenon.
