The average firm going public or issuing new equity underperforms the market in the long run. This underperformance could be related to the endogeneity of the number of new issues if new issues cluster after periods of high abnormal returns on new issues. In such a case, ex post measures of new issue abnormal returns may be negative on average, despite the absence of ex ante abnormal returns. We evaluate this endogeneity problem in event studies of long-run performance. We argue that it is unlikely that the endogeneity of the number of new issues explains the long-run underperformance of equity issues.

This paper shows that there is a close relation between corporate governance and the portfolios held by investors. Most firms in countries with poor investor protection are controlled by large shareholders, so that only a fraction of the shares issued by firms in these countries can be freely traded and held by portfolio investors. We show that the prevalence of closely-held firms in most countries helps explain why these countries exhibit a home bias in share holdings and why U.S. investors underweight foreign countries in their portfolios. We construct an estimate of the world portfolio of shares available to investors who are not controlling shareholders (the world float portfolio). The world float portfolio differs sharply from the world market portfolio. In regressions explaining the portfolio weights of U.S. investors, the world float portfolio has a positive significant coefficient but the world market portfolio has no additional explanatory power. This result holds when we control for country characteristics. An analysis of foreign investor holdings at the firm level for Sweden confirms the importance of the float portfolio as a determinant of these holdings.

This paper studies the relation between fundperformance and fund attributes in the Swedishmarket. Performance is measured as the alpha in alinear regression of fund returns on severalbenchmark assets, allowing for time-varying betas.The estimated performance is then used in across-sectinal analysis of the relation betweenperformance and fund attributes such as pastperformance, flow, size, turnover, and proxies forexpenses and trading activity. The results show thatgood performance occurs among small equity funds,low fee funds, funds whose trading activity is highand, in some cases, funds with good pastperformance.
