waves. The empirical focus concerns the estimation of a structural demand model for the US railroad industry. Then, the … demand estimates are used to compute the evolution of the mark-ups, the quality of the freight services provided, and the … explicitly into account this attrition issue. I find that the algorithm produces more plausible estimates of demand coefficients …

This paper develops asymptotic theory for estimated parameters in differentiated product demand systems with a fixed … well additional bias terms in the asymptotic expansion of the estimator. If R does not increase as fast as T, the leading … bias term dominates the leading variance term and the asymptotic distribution might not be centered at 0. This paper …
