Abstract
We develop a framework that uses price and quantity information on both establishments' outputs and inputs to assess the roles, on establishment dynamics and welfare, of technical efficiency, input prices, demand/quality, idiosyncratic markups, and residual wedges. Our strategy nests previous approaches limited by data availability. In our application, demand/quality is found to dominate the cross sectional variability of sales and sales growth, while quality-adjusted input prices and residual wedges play dampening roles, especially at birth. Markups play only a modest role for cross-sectional variability of sales and sales growth but are important in explaining welfare losses from revenue productivity dispersion.
