Abstract
Using firm-level Compustat data from 1971 to 2000, we report a substantial cross-industry variation of allocative efficiency in capital expenditure in the US economy. Industries with higher allocative efficiency are the ones with higher firm-level value-added growth heterogeneity, higher information transparency captured by firm-specific stock return volatility and faster long-run productivity growth. This finding is consistent with the idea of creative destruction, where a well-functioning market mechanism sharply distinguishes winners from losers and thus enhances economic growth in the long run. Allocative efficiency has a substantial economic significance and explains as much as 24.5% of the difference in long-run industry productivity growth.

Notes
1Intuitively speaking, if stock prices do not reflect private information on companies, all the stocks tend to move together reflecting common public information. Section III discusses more about this variable and its relationship with efficient capital allocation.
2We exclude financial industries (SIC 6000–6999).
