This paper investigates and extends the computationally attractive nonparametric random coefficients estimator of Fox, Kim, Ryan, and Bajari (2011). We show that their estimator is a special case of the nonnegative LASSO, explaining its sparse nature observed in many applications. Recognizing...

This paper addresses the impact of rising international trade exposure on individual earnings profiles in heterogeneous worker-establishment matches. We exploit rich panel data on job biographies of manufacturing workers in Germany, and apply a high-dimensional fixed effects approach to analyze...

We use a large sample of German workers to analyze the effect of low-wage competition with China and Eastern Europe (the East) on the wage structure within German manufacturing industries. Utilizing the method by Abowd et al. (1999), we decompose wages into firm and worker components. We find...

Over the last 20 years the trade literature repeatedly documented the trade-reducing effects of inter- and intra-national borders. Thereby, the puzzling size and persistence of observed border effects from the beginning raised doubts on the role of underlying political borders. However, when...
