Insuring Consumption Using Income-Linked Assets

We evaluate financial assets with payoffs linked to individual labor income, as conceived by Shiller (2003) and others. Using a realistically calibrated life-cycle model, we find that such assets can generate nontrivial welfare benefits, depending on the precise structure of the instrument. However, the assets we consider can only eliminate a relatively small fraction of the welfare costs of labor income risk over the life cycle. We highlight the fact that although the purpose of such assets is to smooth consumption across states of nature, one must also consider the assets' effects on households' ability to smooth consumption over time.
