Abstract. In this article, we present the pseudounit command, which estimates
pseudounit values in cross-sections of household expenditure surveys without
quantity information. Household surveys traditionally record only expenditure
information. The lack of information about quantities purchased precludes the
possibility of deriving household-specific unit values. We use a theoretical
result developed by Lewbel (1989, Review of Economic Studies 56:
311–316) to construct pseudounit values by first reproducing
cross-sectional price variation, then adding this variability to the aggregate
price indexes published by national statistical institutes. We illustrate the
method with an example that uses a time series of cross-sections of Italian
household budgets.
