How unemployment insurance savings accounts affect employment duration : evidence from Chile

The introduction of unemployment insurance savings accounts (UISA) in Chile in October 2002 introduced more comprehensive unemployment protection while decreasing the opportunity costs of job change. Being the first to empirically investigate the effect of UISA on employment duration, this paper examines (i) whether the introduction of UISA affected employment duration among formal private sector workers, and (ii) the magnitude of this effect. The analysis is performed on longitudinal social protection data and uses survival analysis techniques, including non-parametric, semi-parametric and parametric analysis, and competing-risk models. The paper finds that workers affiliated to the scheme show an increased hazard ratio of leaving employment, or accelerated time to employment termination. The effect is larger for workers becoming unemployed or inactive compared to workers changing jobs. The results provide strong support that the introduction of UISA led to shorter employment duration and higher mobility of the workforce in Chile.
