Knowledge that Transforms

We provide measures of absolute and relative equity agency costs for corporations under different ownership and management structures. Our base case is Jensen and Meckling's (1976) zero agency‐cost firm, where the manager is the firm's sole shareholder. We utilize a sample of 1,708 small corporations from the FRB/NSSBF database and find that agency costs (i) are significantly higher when an outsider rather than an insider manages the firm; (ii) are inversely related to the manager's ownership share; (iii) increase with the number of nonmanager shareholders, and (iv) to a lesser extent, are lower with greater monitoring by banks.

Emerging markets like India have poorly functioning institutions, leading to severe agency and information problems. Business groups in these markets have the potential both to offer benefits to member firms, and to destroy value. We analyze the performance of affiliates of diversified Indian business groups relative to unaffiliated firms. We find that accounting and stock market measures of firm performance initially decline with group diversification and subsequently increase once group diversification exceeds a certain level. Unlike U.S. conglomerates' lines of business, and similar to the affiliates of U.S. LBO associations, affiliates of the most diversified business groups outperform unaffiliated firms.

If asset returns have systematic skewness, expected returns should include rewards for accepting this risk. We formalize this intuition with an asset pricing model that incorporates conditional skewness. Our results show that conditional skewness helps explain the cross‐sectional variation of expected returns across assets and is significant even when factors based on size and book‐to‐market are included. Systematic skewness is economically important and commands a risk premium, on average, of 3.60 percent per year. Our results suggest that the momentum effect is related to systematic skewness. The low expected return momentum portfolios have higher skewness than high expected return portfolios.

Individual investors who hold common stocks directly pay a tremendous performance penalty for active trading. Of 66,465 households with accounts at a large discount broker during 1991 to 1996, those that trade most earn an annual return of 11.4 percent, while the market returns 17.9 percent. The average household earns an annual return of 16.4 percent, tilts its common stock investment toward high‐beta, small, value stocks, and turns over 75 percent of its portfolio annually. Overconfidence can explain high trading levels and the resulting poor performance of individual investors. Our central message is that trading is hazardous to your wealth.
