independence of a class of economic choice models. We state an economic property known as reducibility and prove that reducibility ensures linear independence and hence identification. Reducibility makes verifying the identification of nonlinear models easy. We use our mixtures framework to...

I estimate the relative magnitudes of worker switching costs and whether the employer switching of experienced engineers responds to outside wage offers. Institutional features imply that voluntary turnover dominates switching in the market for Swedish engineers from 1970 to 1990. I use data on...

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...

We empirically study bidding in the C Block of the US mobile phone spectrum auctions. Spectrum auctions are conducted using a simultaneous ascending auction design that allows bidders to assemble packages of licenses with geographic complementarities. While this auction design allows the market...
