This paper tests empirically whether the effect of idiosyncratic income shocks on aggregate consumption depends on institutional features of national labour markets. The results show that in a sample of 15 OECD countries institutional heterogeneity is a significant determinant of the response of household consumption to country-specific income shocks.
This is consistent with the idea that institutionally-provided social insurance may help increase income stability when
people differ in their ability to access financial markets and smooth consumption fluctuations.
