ANÁLISIS POR COHORTES DE LA PARTICIPACIÓN LABORAL EN MÉXICO (1987-2009).

This paper decomposes labor force participation, the unemployment rate, and the employment shares of self-employment, and of the formal and informal salaried sectors into age, cohort, and time effects. The life cycle patterns of labor force participation and formal employment follow a standard inverted U-shape. Younger workers are more likely to participate in the informal salaried sector, while self- employment increases monotonically with age. However, significant informal salaried employment is also observed among older unskilled workers and women. Strong countercyclical variations are observed for the informal salaried sector, while the opposite occurs for the formal sector. Self-employment fluctuations are countercyclical with a lag. We find an "added worker" effect only during severe recessions among unskilled women. Long-run generational effects show a steadily rising participation in the informal sector with a corresponding decline in formality among newer generations of salaried workers. Some preliminary explanations for this fact are discussed. [ABSTRACT FROM AUTHOR]
