In the case of unemployment insurance savings accounts, mobility between formal and informal jobs limits coverage. Even in Chile, where informality is the lowest in Latin America, unemployed workers are, on average, much less likely to have been in formal jobs with written contracts - around one-third report having had an atypical contract in their last job, and around 30% no contract at all. While it is the individualisation of risk management that helps keep costs down in these schemes, it is the unbundling that enables them to capture the latent demand for unemployment or health insurance (including when it emanates from some informal workers). In fact, one of the ways in which social protection can contribute not only to social cohesion but to growth is by allowing households to overcome the market failures that prevent them from insuring against both life risks and certain covariant risks (Dercon, 2011).
