The link between consumption and leisure under Cobb-Douglas preferences:Some new evidence

The assumption of multiplicative non-separable (Cobb-Douglas) consumer preferences is a key assumption for analyzing the interdependence of consumption and leisure choices. In this paper we solve the consumer utility maximization problem under these preferences and derive a simultaneous system of two equations corresponding to a static and an inter-temporal equation of consumption and leisure choice. The system is estimated with GMM to obtain consistent estimates of the consumer's preference parameters, of which the relative weight of consumption in the utility function is found to be much higher than that commonly assumed in DSGE model calibration exercises.
