Capital allocation, stock return volatility and productivity growth in US industries

초록

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.
