I present the fact that wage gaps due to firm size increase with job responsibility. I use Swedish data to determine whether wage gaps increase with a direct measure of job responsibility, to compare the age patterns of the wage gaps for blue- and white-collar workers, and to compare wages by...

The random coefficients multinomial choice logit model, also known as the mixed logit, has been widely used in empirical choice analysis for the last thirty years. We prove that the distribution of random coefficients in the multinomial logit model is nonparametrically identified. Our approach...

This article estimates worker switching costs and how much the employer switching of experienced engineers responds to outside wage offers. I use data on engineers across Swedish private sector firms to estimate the relative importance of employer wage policies and switching costs in a dynamic...

We propose a method to structurally estimate the deterministic component of bidder valuations in FCC spectrum auctions, and apply it to the 1995-1996 C block auction. We base estimation on a pairwise stability condition: two bidders cannot exchange two licenses in a way that increases the sum of...
