This paper examines the agency problem between shareholders and debtholders of Japanese and U.S. firms. Whereas U.S. institutional investors are restricted from doing so, Japanese financial institutions take large equity positions in firms to which they lend, particularly in firms more susceptible to the agency problem. Debt ratios of U.S. firms are negatively related to the firm's potential to engage in risky, suboptimal investments, whereas Japanese debt ratios show no such relation. The evidence is consistent with the notion that the agency problem is mitigated to a greater degree in Japan than in the U.S.

Share-price responses to 95 announcements of increased research and development (R & D) spending are significantly positive on average, even when the announcement occurs in the face of an earnings decline. High-technology firms that announce increases in R & D spending experience positive abnormal returns on average, whereas announcements by low-technology firms are associated with negative abnormal returns. Further, in our cross-sectional analyses we find that higher R & D intensity than the industry average leads to larger stock-price increases only for firms in high-technology industries.
