This paper presents a quantitative model of productivity dispersion to explain why inefficient producers are slowly selected out of the ready-mix concrete industry. Measured productivity dispersion between the 10th and 90th percentile falls from a 4 to 1 difference using OLS, to a 2 to 1...

We estimate the effects of electricity shortages on Indian manufacturers, instrumenting with supply shifts from hydroelectric power availability. We estimate that India's average reported level of shortages reduces the average plant's revenues and producer surplus by five to ten percent, but...

Fluctuations in demand cause some plants to exit a market and other to enter.Would eliminating these fluctuations reduce plant turnover? A structural model of entry and exit in concentrated markets is estimatedfor the ready-mix concrete industry, using plant level data from the U.S. Census. The...
