Pension schemes and labor supply in the formal and informal sector

Abstract

This paper analyzes the participation path of workers in the formal and informal sectors throughout their lives and their pension eligibilities, as well as how the social security scheme can change the aforementioned participation path. High levels of informality have impacts on the benefits that workers receive, especially their pension benefits. I use Argentinean panel data from 1995 to 2008 to construct a structural discrete choice model which estimates the population’s labor path and their pension eligibilities. I find evidence that low-educated workers have difficulties to obtain a pension by the age of 65 and even by age 70. Policy experiments show that if the parameters are fixed as in the pay-as-you-go (PAYG) model, there is a slight reduction in the years worked in the formal sector and the percentage of workers who obtain a Full pension. If the pension requirements (minimum age and years contributing) are stricter, there is an increase in the years spent in the formal sector but it is not sufficient to achieve the benchmark level of pension coverage. If the requirements are looser, there is a reduction in the amount of time spent in formality to contribute up to the new threshold.
