Household Production and the Elasticity of Marginal Utility of Consumption

Publisher's full text

The popular approach to estimating the elasticity of marginal utility of consumption (EMUC) (Chetty 2006, "A New Method of Estimating Risk Aversion." American Economic Review 96 (5):1821-1834. doi:10.1257/aer.96.5.1821. http://www.aeaweb.org/articles.php?doi=10.1257/aer.96.5.1821) is here extended by including household production. It is shown that this generalization of the model is important as omission of household production may lead to bias, as demonstrated in a numerical sensitivity analysis. An extended model with household production is used to derive new EMUC formulas. Empirical estimates based on current evidence of the included parameters suggest a lower bound for EMUC of about 0.9.
