%X In this paper we estimate a demand for private medical services equation based on the
tradition of the Grossman´s model of demand for health using data for a panel of
Spanish households. The econometric specification accounts for the censored nature of
the data, which arises from no participation and infrequency of purchases, and the
existence of unobserved heterogeneity, which arises from the non observability of
health stata. Our evidence suggests that ignoring these features can have a significant
impact on the size, sign and significance of the model estimates. The estimates for the
participation and consumption processes also suggest that the deduction of
expenditures on health care currently applicable in the Spanish tax system are positively
associated to income and fertility.
