Asymmetric Business-Cycle Risk and Social Insurance


This paper studies the business-cycle variation in higher-order (labor) income risk-that is, risks that are captured by moments higher than the variance of income changes. We examine the extent to which such risks can be smoothed within households or with government social insurance and tax policies. We use panel data from three countries that differ in many aspects relevant for our analysis: the United States, Germany, and Sweden. Our analysis has three main results. First, analyzing individual gross labor income, we document that skewness is procyclical and dispersion (variance) is flat and acyclical in Germany and Sweden, as was previously documented for the United States. The same patterns hold true for groups defined by education, gender, occupation, and public- versus private-sector jobs. Second, within-household smoothing appears to be not effective at mitigating business cycle fluctuations in skewness, and household- level income displays cyclical patterns that are very similar to individual income. Third, government tax and transfer programs blunt some of the largest declines in incomes, reducing procyclical fluctuations in skewness. The resulting welfare gain-through the lens of a structural model-amounts to 1.3% in consumption- equivalent terms for Sweden (for which we are able to perform this calculation). However, the remaining risk (in household disposable income) is still substantial: households are willing to pay 4.6% of their consumption to completely eliminate procyclical fluctuations in skewness.
