Noncooperative Household Consumption with Caring

Abstract

We present a household consumption model that accounts for caring house- hold members, while allowing for noncooperative behavior in decisions on pub- lic goods. The intrahousehold consumption outcome critically depends on the degree of caring between the household members. By varying the degree of in- trahousehold caring, the model encompasses a whole continuum of household consumption models that are situated between the fully cooperative model and the noncooperative model without caring. This feature is used to define a measure for the degree of cooperation within the household. We also establish a dual characterization of our noncooperative model with caring preferences: we show that the model is dually equivalent to a noncooperative model with non-caring preferences that is characterized by intrahousehold transfers. Fi- nally, following a revealed preference approach, we derive testable implications of the model for empirical data. We demonstrate the practical usefulness of the model through an illustrative application.household consumption;caring preferences;intrahousehold coop- eration;Nash equilibrium;revealed preferences
