This paper proposes using the Gaussian approximation, also known as quantile coupling, to estimate a quantile model. The quantile coupling allows one to apply the standard Gaussian-based estimation and inference to the transformed data set. The resulting estimator is asymptotically normal with a...

This paper analyzes entry by comparing employment and sales penetration rates for new manufacturing firms of different entry cohorts. We find that penetration rates depend on entry year with no further year effects, and rise initially then fall with age.
