This paper provides new identification results for a large class of (static) consumer problems that contain (production) functions in the budget constraints. I show that the mere structure of the consumer problem is sufficient to nonparametrically identify the part of the production functions...

This report focuses on households’ behaviour in relation to food consumption. It presents the results of follow-up econometric analysis of the 2011 OECD Survey on Environmental Policy and Individual Behaviour Change (EPIC). This report complements the overview of the survey data provided in...

Varian (1988) showed that the utility maximization hypothesis cannot be falsified when only a subset of goods is observed. We show that this result does not hold under the assumptions that unobserved prices and expenditures remain constant. These assumptions are naturally satisfied in laboratory...

This paper deals with different concepts of income elasticities of demand for a heterogenous population and the relationship between individual and aggregate elasticities is analyzed. In general, the aggregate elasticity is not equal to the mean of individual elasticities. The difference depends...

We characterize optimal consumption policies in a recursive intertemporal utility framework with local substitution. We establish existence and uniqueness and a version of the Kuhn-Tucker theorem characterizing the optimal consumption plan. An explicit solution is provided for the case when the...

We study users' response to sponsored-search advertising using data from Microsoft's Live AdCenter distributed in the "Beyond Search" initiative. We estimate a structural model of utility maximizing users, which quantifies "user experience" based on their "revealed preferences," and predicts...
