Risk Sharing of Disaggregate Macroeconomic and Idiosyncratic Shocks

We estimate the extent to which idiosyncratic and disaggregate macro shocks (such as regional and industry shocks) are not shared in the economy. Comparing the degree to which idiosyncratic and disaggregate macro shocks are not shared grants a deeper understanding as to why the economy lacks in specific areas of risk sharing arrangements. As well, it can point to areas where the economy’s risk sharing capability can be enhanced. Using household data from the Panel Study of Income Dynamics, we find that a negligible amount of risk (around 10%) is shared in the aggregate, about 50% is shared within regions and industries, while the remaining 40% is not shared with other households. These findings suggest that given the low level of international risk sharing, increased international integration may not lead to a significant increase in international risk sharing.
