VENTURE CAPITAL AND INNOVATION: WHICH IS FIRST?

Policy‐makers typically interpret positive relations between venture capital (VC) investments and innovations as evidence that VC investments stimulate innovation (VC‐first hypothesis). This interpretation is, however, one‐sided because there may be a reverse causality that innovations induce VC investments (innovation‐first hypothesis): an arrival of new technology increases demand for VC. We analyze this causality issue of VC and innovation in the US manufacturing industry using both total factor productivity growth and patent counts as measures of innovation. We find that, consistent with the innovation‐first hypothesis, total factor productivity growth is often positively and significantly related with future VC investment. We find little evidence that supports the VC‐first hypothesis.     

EARTHQUAKE RISKS AND LAND PRICES: EVIDENCE FROM THE TOKYO METROPOLITAN AREA*

The current paper empirically addresses risk aversion of households and firms toward earthquake risks using a hazard map compiled for the entire region by the Tokyo metropolitan government in 1998. It finds strong evidence for the impact of earthquake risks on land pricing; land prices have been substantially lower in risky areas than in safe areas. That impact became more evident in the 1990s than in the 1980s, indicating that households and firms were becoming more sensitive to earthquake risks. In addition, this paper carefully examines the consistency of the estimated magnitude of earthquake risk premiums within a framework of the expected utility hypothesis.
