Trendsetters wish to be perceived as the type that defines normative behavior. Incorporating norm formation in Bernheim (1994)’s model yields equilibria with social considerations concentrating behavior, allowing multiple conformist pools. Refinements link each pooling equilibrium to a unique...

This paper proposes a conjugate Bayesian regression model to estimate the covariance matrix of a large number of securities. Characterizing the return generating process with an unrestricted factor model, prior beliefs impose structure while preserving estimator consistency. This framework...

Structural models of demand founded on the classic work of Berry, Levinsohn, and Pakes (1995) link variation in aggregate market shares for a product to the influence of product attributes on heterogeneous consumer tastes. We consider implementing these models in settings with complicated...
