Roberto Avarez kindly shared Chilean exporter and product data for the year 2000, for which we report comparable results to our Brazilian findings in an online Data Appendix at URL econ.ucsd.edu/muendler/research. We present an extension of our model to nested CES in an online Technical Appendix at the same URL. Oana Hirakawa and Olga Timoshenko provided excellent research assistance.
