This paper shows how two standard models of consumption-risk-sharing-self-insurance through borrowing and saving and limited commitment to insurance contracts-replicate similarly well the standard, second-moment measures of insurance observed in US micro data. A nonparametric analysis, however, reveals strongly contrasting and counterfactual joint distributions of consumption, income and wealth. Method of moments estimation shows how measurement error in consumption eliminates excessive skewness and smoothness of consumption growth. Moreover, counterfactual nonlinearities disappear at high-estimated risk aversion under self-insurance, but are a robust feature of limited commitment. Its shape of insurance thus argues in favor of the self-insurance model.
