Abstract
Informal self-employment is a major source of employment in developing countries. Its cyclical behavior is important to our understanding of the functioning of LDC labor markets, but turns out to be surprisingly complex. We develop a flexible model with two sectors: a formal salaried (tradable) sector that may be affected by wage rigidities, and an informal (non tradable) self-employment sector faced with liquidity constraints to entry. This labor market is then embedded in a standard small economy macro model. We show that different types of shocks interact with different institutional contexts to produce distinct patterns of comovement between key variables of the model: relative salaried/self-employed incomes, relative salaried/self-employed sector sizes and the real exchange rate. Model predictions are then tested empirically for Argentina, Brazil, Colombia, and Mexico. We confirm episodes where the expansion of informal self-employment is consistent with the traditional segmentation views of informality. However, we also identify episodes where informal self-employment behaves "pro-cyclically"; here, informality is driven by relative demand or productivity shocks to the non tradable sector.

Publication The Determinants of Rising Informality in Brazil : Evidence from Gross Worker Flows(World Bank, Washington, DC, 2007-10)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.Publication Cyclical Movements in Unemployment and Informality in Developing Countries(World Bank, Washington, DC, 2008-06)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.Publication Exchange Rate Appreciations, Labor Market Rigidities, and Informality(World Bank, Washington, DC, 2002-02)This paper works at the interface of the literature exploring the raison d'etre of the informal labor market and that explaining the real exchange rate appreciations occurring in many Latin American countries during periods of reform. The authors first build a small country-Australian style model where the informal sector is seen as an unregulated non-tradables sector, augmented by heterogeneity in entrepreneurial ability and capital adjustment costs. They then examine the behavior of the model with and without a formal sector rigidity. It shows that the co-movements of relative formal/informal incomes, formal/informal sector size, and the real exchange rate can offer insight into the level of distortion in the labor market and the source of exchange rate fluctuations. The paper then explores time series data from Brazil, Colombia and Mexico using multivariate co-integration techniques to establish what "regime" each country is in at various periods of time. Mexico appears to be relatively undistorted and the 1987-92 appreciation appears to be largely a function of a boom in the non-tradables sector rather than wage inertia. In spite of a secular expansion of the informal sector there is little evidence of dualism or of a rigidity driven appreciation of the Real, from 1993-1996. Post 1995 Colombia corresponds to a classic segmented labor market and an appreciation partly driven by labor market rigidities. Graphical analysis suggests that neither the Argentine appreciation (1988-1992) or the celebrated Chilean appreciation (1975-1982) were driven by inertial forcesPublication Human Capital, Trade Liberalization, and Income Risk(World Bank, Washington, DC, 2007-07)Using data from Mexico, the authors study empirically the link between trade policy and individual income risk and the extent to which this varies across workers of different human capital (education) levels. They use longitudinal income data on workers to estimate time-varying individual income risk parameters in different manufacturing sectors in Mexico between 1987 and 1998, a period in which the Mexican economy experienced substantial changes in trade policy. In a second step, they use the variations in trade policy across different sectors and over time to estimate the link between trade policy and income risk for workers of varying education levels. The authors' findings are as follows. The level of openness of an economy is not found to be related to income risk for workers of any type. Furthermore, changes in trade policy (that is, trade policy reforms) are not found to have any effect on the risk to income faced by workers with either low or high levels of human capital. But workers with intermediate levels of human capital are found to experience a statistically and economically significant increase in income risk immediately following liberalization of trade. The findings thus point to an interesting non-monotonicity in the interaction between human capital, income risk and trade policy changes.Publication Measuring the Impact of Minimum Wages : Evidence from Latin America(World Bank, Washington, DC, 2001-04)The authors provide an overview of minimum wage levels in Latin America and their true impact on the distribution of wages, using both numerical measures and kernal density plots for eight countries (Argentina, Bolivia, Brazil, Chile, Colombia, Honduras, Mexico, and Uruguay). They especially try to identify "numeraire" effects--where the minimum is used as a reference higher in the wage distribution--and "lighthouse" effects--where it influences wage setting in the unregulated or "informal" sector. Their main findings: First, statutory minimum wages are often misleading, and graphical methods may be more reliable. Second, the minimum wage's effect on wage setting extends far beyond what is usually considered and probably beyond the effect in industrial countries. Using panel employment data from Colombia, where minimum wages seem high and binding, the authors quantify the minimum wage's effects on wages and on the probability of becoming unemployed. The Colombian case confirms the evidence offered by kernal density estimates: 1) The minimum wage can have an important impact on wage distribution in the neighborhood of the minimum wage. 2) The effects echo up the wage distribution in a clear demonstration of the "numeraire" effect. That this effect is stronger in Latin America than in the United States suggests that the minimum wage induces further-reaching rigidities in the labor market. The trade-off between any possible effect on poverty and reduced flexibility is likely to be more severe in countries where this is the case. The effects on employment, and unemployment, are substantial. 3) Informal salaries wages are also affected, confirming the graphical evidence of strong lighthouse effects. Self-employment earnings are not, however, confirming that the minimum wage is not simply serving as a measure of inflationary expectations.
