Roberts, Mark J.; Das, Sanghamitra; Tybout, James R. - National Bureau of Economic Research (NBER) - 2001
As the exchange rate, foreign demand, production costs and export promotion policies evolve, manufacturing firms are continually faced with two issues: Whether to be an exporter, and if so, how much to export. We develop a dynamic structural model of export supply that characterizes these two...

Unobserved Product Differentiation in Discrete Choice Models: Estimating Price Elasticities and Welfare Effects
Ackerberg, Daniel; Rysman, Marc - National Bureau of Economic Research (NBER) - 2002
Standard discrete choice models such as logit, nested logit, and random coefficients models place very strong restrictions on how unobservable product space increases with the number of products. We argue (and show with Monte Carlo experiments) that these restrictions can lead to biased...

Pindyck, Robert S. - National Bureau of Economic Research (NBER) - 2005
Sunk costs play a central role in antitrust economics, but are often misunderstood and mismeasured. I will try to clarify some of the conceptual and empirical issues related to sunk costs, and explain their implications for antitrust analysis. I will be particularly concerned with the role of...
