Estimation of Nonparametric Functions in Simultaneous Equations Models,
with an Application to Consumer Demand

Donald J. Brown and Rosa L. Matzkin

March 1998

We present a method for consistently estimating nonparametric functions and distributions in simultaneous equations models. This method is used to identify and estimate a random utility model of consumer demand. Our identification conditions for this particular model extend the results of Houthakker (1950), Uzawa (1971) and Mas-Colell (1977), where a deterministic utility function is uniquely recovered from its deterministic demand function.
