Income risk and the benefits of social insurance

"This paper examines the welfare consequences of social safety nets in developing economies relative to developed economies. Using panel surveys of households in Indonesia and the United States, we find that food consumption falls by approximately ten percent when individuals become unemployed in both countries. This finding suggests that introducing a formal social insurance program would have small benefits in terms of reducing consumption fluctuations in Indonesia. However, in contrast with households in the U.S., Indonesians use costly methods such as reducing human capital investment to smooth consumption. The primary benefit of social insurance in developing countries may therefore come not from consumption smoothing itself but from reducing the use of inefficientsmoothing methods"--National Bureau of Economic Research web site.
