The value of a promise: The effect of future pension benefits on labor supply in a developing economy [PDF]

This paper describes how future pension benefits affect labor supply in economies that have an informal sector (i.e., a sector that does not comply with government regulation). From the perspective of a worker, a formal-sector job will offer long-run gains because it will increase the worker's expected pension benefits in the future. If workers take those gains into account when they search for formal-sector jobs, the pension system affects formal-sector labor supply. I estimate the causal link between future pension benefits and formal-sector labor supply using a cohort-based reform undertaken in Colombia. I find that a reduction in future pension benefits generates a reallocation of labor supply from taxable (formal) to non-taxable (informal)jobs and that this change does not affect labor force participation. The estimated effect is heterogeneous and is consistent with the predictions of a life-cycle model with a pension system and informal job opportunities. The effect is concentrated among workers for whom the minimum qualifying conditions are binding, and among workers with higher expected pension gains. The results presented here suggest that pension reforms have the potential to create large efficiency costs, an effect that should be considered when designing pension programs.

Effects of Future Pension Benefits on Pre-retirement Labor Supply: Evidence from Chile [PDF]

I estimate the effect of future pension benefits on pre-retirement labor supply for a representative sample of Chilean workers. Using non-linear patterns in pension benefit formulas and a reform that changed non-contributory pensions, I estimate the effect of pension accrual and expected pension wealth on labor force and contributory-sector participation, labor earnings, and hours worked. I find that the effect is related to the impact of pension accrual on the probability to contribute to the pension system. The effect is heterogeneous, and is concentrated among middle-age workers, low-skilled workers, workers with no savings, and workers with higher financial literacy.

Costs of Regulation and Creation of Formal-Sector Jobs: Evidence from Colombia’s First Job Act

In this paper, I study the effects of the costs of regulation on the creation of formal-sector jobs. To analyze the extent of the costs of regulation on determining both formal employment and wages, I use the variation induced by the Colombian First Job Act. The Act granted tax exemptions for new registered firms with 50 workers or less, and granted tax credits for existing firms hiring workers under 28. Since the Act generated variation between groups of firms and workers over time, I carried out a Differences-in-Differences research design to obtain reduced-form estimates of the causal effect of regulation costs on the formal-sector employment and wages. The results indicate that changes in the regulation costs for small firms has a positive and significant impact on employment and wages, and this effect is especially large for small employers. Similarly, changes in payroll-taxes have positive and significant effects on both employment and wages. In both cases, the estimated effect on employment is larger than the estimated effect on wages, which may be explained by the binding effects of the minimum wage and an integrated labor market, opposite to a segregated labor market in which informal workers cannot get jobs in the formal sector.
