Abstract

In this paper we discuss an empirical strategy that allows researchers to impute consumptiondata from the CEX to the PSID. The strategy consists of inverting a demand for food equationestimated in the CEX. We discuss the conditions under which such procedure is successful inreplicating the trends of the first two moments of the consumption distribution. We argue thattwo factors appear to be empirically relevant: accounting for differences in the distribution offood expenditures in the two data sets, and accounting for the presence of measurement error inconsumption data in the CEX.
