Using 550 million limit orders submitted in the Korea Stock Exchange, we estimate demand and supply elasticities of heterogeneous investor types and their changes around the Asian financial crisis. We find that domestic individuals have substantially more inelastic demand and supply curves than...

Technological innovation is not a blessing for all firms, or for investors holding the market. In the late 20th century US, individual firms' stock returns correlate positively with their own productivity growth, yet the market return correlates negatively with aggregate productivity growth,...

Using U.S. firm-level data from 1971 to 2000, this paper quantifies the importance of production input reallocation in explaining the information technology (IT) driven productivity growth. We find that cross-industry variation in input reallocation explains more than 30% of differences in the...

Traditional U.S. industries with higher firm-specific stock return and fundamentals performance heterogeneity use information technology (IT) more intensively and post faster productivity growth in the late 20th century. We argue that this mechanically reflects a wave of Schumpeter's creative...

Traditional U.S. industries with higher firm-specific stock return and fundamentals performance heterogeneity use information technology (IT) more intensively and post faster productivity growth in the late 20th century. We argue that elevated firm performance heterogeneity mechanically reflects...

U.S. firms' stock return volatility rose fivefold from 1971 through 2000 and then reverted to near 1971 levels by 2006. This was driven mainly by a rise and fall in the firm-specific, rather than systematic, component of volatility. Firm-level total factor productivity growth volatility...

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...

In this paper, we establish a link between firm heterogeneity and long-run economic growth both theoretically and empirically. We show that firms' technological heterogeneity creates the diversification effect for R&D financiers, facilitating R&D investment, and thus leading to long-run economic...
