This paper analyzes how changes in the social security scheme affect the participation path of workers between the formal and the informal sectors. The choice between the formal and informal sectors is completely voluntary. In this framework, individuals, depending on the retirement program and...

We study the dynamic general equilibrium effects of introducing a social pension program to elderly informal sector workers in developing countries who lack formal risk sharing mechanisms against income and longevity risk. To this end, we formulate a stochastic dynamic general equilibrium model...

We investigate the effects of extending the coverage of social security to uncovered elderly individuals in the informal sector in developing countries. We use a stochastic overlapping generations framework and incorporate important characteristics of developing countries including family...

We study the dynamic general equilibrium effects of introducing a social pension program to elderly informal sector workers in developing countries who lack formal risk sharing mechanisms against income and longevity risks.

The informal sector is an extensive phenomenon in developing countries. While some of its implications have drawn considerable attention in the literature, one relatively unexplored aspect has to do with the saving patterns of workers and firms and how these might influence aggregate savings and...

We develop an equilibrium wage-posting model with heterogeneous firms that decide to locate in the formal or the informal sector and workers who search randomly on and off the job. We estimate the model on Brazilian labor force survey data. In equilibrium, firms of equal productivity locate in...

Accepted for publication, Journal of Economic Dynamics and Control The aim of this paper is to quantify the role of formal-sector institutions in shaping the demand for human capital and the level of informality. We propose a firm dynamics model where firms face capital market imperfections and...

The aim of this paper is to explore the use of administrative data to study the choices of firms relating to the utilization of regular and irregular workers. The data are collected by the INPS (National Social Security Administration) during inspection activity aimed to catch irregular workers...
