In contrast to Aryal, Perrigne and Vuong (2009), this note shows that in an insurance model with multidimensional screening when only information on whether the insuree has been involved in some accident is available, the joint distribution of risk and risk aversion is not identi fied

The social and the private returns to education differ when education can increase productivity, and also be used to signal productivity. We show how instrumental variables can be used to separately identify and estimate the social and private returns to education within the employer learning...

We study asymmetric first-price procurements with unobserved heterogeneity and asymmetric risk-aversion. For this model, we propose a new empirical method that allows us to predict the expected procurement cost at any reserve price. Being able to perform such detailed counterfactual analysis is...

We propose an empirical framework for a Cournot-oligopoly model where firms have private information about their own marginal costs. Considering a linear demand with random intercept, we characterize the Bayesian Cournot-Nash equilibrium and determine testable implications from the joint...
