Using data on all employees at listed companies in Taiwan, we find that the bias toward employer stocks is generic to individual investor decision making, but not limited to retirement plans. Seventy-one percent of the sample employees invest in employer stocks and employer stocks make up on average 47% of employee equity portfolios. The underdiversification resulting from the bias toward employer stocks is very costly. Holding current portfolio risk constant, employees forego 4.89% per annum in raw returns by investing in employer stocks, which represents 39.74% of their average 1998 salary income. Our findings have important implications for social security reform and retirement account management.

This paper examines the effect of commercial bank entry on underwriting spreads for IPOs, SEOs, and debt issues using a long time series that spans 30 years, from 1975 to 2004. We find that, on average, commercial banks charge lower spreads of approximately 72 basis points for IPOs, 43 basis points for SEOs, and 14 basis points for debt over the entire sample period. The economic impact of commercial banks on lowering underwriting spreads is most significant when commercial banks were allowed to enter via Section 20 subsidiaries but persists beyond. Commercial bank entry into underwriting appears to have a procompetitive effect that lasts many years after their initial entry.

We investigate performance effects for China's listed firms when there is a change in the controlling shareholder. These changes include ownership transfers from one state entity to another state entity and from a state entity to a private entity. We find positive performance effects when control is passed to a private entity. In contrast, when the transfer is made to another branch of the state, there is little change in performance. The stock market responds positively to a change in control, with the largest effect observed for private transfers. Our results suggest the Chinese government should continue to sell down its share ownership in listed firms as the transfer of control to private owners enhances corporate profitability and efficiency. Moreover, to help ownership reform, China should encourage an active market for corporate control.

Standard tests of portfolio efficiency neglect the existence of illiquid wealth. The most important illiquid asset in household portfolios is housing: if housing stock adjustments are infrequent, optimal portfolios in periods of no adjustment are affected by housing price risk through a hedge term and tests for portfolio efficiency of financial assets must be run conditionally upon housing wealth. We use Italian household portfolio data and time series on financial assets and housing stock returns to assess whether actual portfolios are efficient. We find that housing wealth plays a key role in determining whether portfolios chosen by homeowners are efficient.

Using a unique insurance dataset for a sample of Chinese publicly listed companies for the period 1997 through 2003, this study tests the simultaneous linkages between debt capacity, cost of debt, and corporate property insurance. Our results suggest that, on the one hand, a higher cost of debt appears to motivate the use of more property insurance, but high leverage alone does not lead to the purchase of more property insurance. The latter finding might reflect the unique institutional setting of China, for example, where there is a low chanceof legally enforced company liquidation. Also, there is evidence that leverage can interact with tangible assets intensity and exert a positive conjoint effect on the corporate purchase ofproperty insurance. On the other hand, we find evidence that supports that property insurance helps expand insuring firms' debt capacity and helps lower their borrowing costs. However, themoderate evidence on the cost reduction effect suggests that lowering the borrowing cost is likely to be a concern secondary to facilitating corporate borrowing and thereby expanding debt capacity in corporate property insurance decisions in China. Overall, we conclude that debt capacity, cost of debt, and corporate insurance appear to be simultaneously related.

Using stock transactions data along with detailed stockholdings for a comprehensive sample of U.S. actively managed equity mutual funds from 1993 to 2002, this paper empirically examines the effect of liquidity and investment style on the relation between fund size and fund performance. Consistent with Chen, Hong, Huang, and Kubik (2004), I find a significant inverse relation between fund size and fund performance. Further, this inverse relation is stronger among funds that hold less liquid portfolios. The inverse relation between fund size and fund performance is also more pronounced among growth and high turnover funds that tend to have high demands for immediacy. Overall, this paper's findings suggest that liquidity is an important reason why fund size erodes performance.

Theory indicates that frictions (e. g., information and transaction costs) could account for the lower than expected stock market participation rates. This paper examines the hypothesis that there has been a fundamental change in participation and links this change to the reduction of these frictions by the advent of the Internet. Using panel data on household participation rates over the past decade, the results show computer/Internet using households raised participation substantially more than non-computer using households. The increased probability of participation was equivalent to having over $27,000 in additional household income or over two more mean years of education.

This paper provides the first theoretical explanation and the first empirical analysis of contingent value rights (CVRs), which have been used as a means of payment in acquisitions, exchange offers, debt restructurings, Chapter 11 reorganizations, and lawsuit settlements. A CVR is a put option committing to pay additional cash or securities to CVR holders, contingent on the issuer's share price falling below a prespecified reference level. In this paper, we develop a model to show that CVRs can help a higher-intrinsic-value firm to reveal its firm type when the firm faces an asymmetric information problem. Our model predicts that i) when CVRs are offered along with cash or stock, the announcement period abnormal stock return is greater than that in stock offers, ii) firms facing more severe asymmetric information problems are more likely to offer CVRs to signal their firm type, and iii) firms that are relatively more cash-constrained are more likely to offer CVRs rather than cash. We test all three predictions using a sample of mergers and acquisitions. Our empirical results are consistent with the predictions of the model.

This paper examines a firm's debt level, investment timing, and investment scale choices in a continuous-time model where the output price of a good that the firm produces depends on a stochastic demand-shift variable and the total industry supply of the good. Using the simple symmetric Cournot-Nash equilibrium assumption that all firms are identical and therefore follow the same financing and investment strategies, we show that competition decreases the output price and hence encourages a firm to wait for a higher demand level before it is profitable to invest. We also demonstrate how uncertainty, bankruptcy costs, and corporate taxation affect the firm's financing and investment decisions.

This paper investigates whether corporate payout policy is associated with insiders' share holdings and their tax preferences. We find that insider ownership and the implied tax liabilities are positively related to a firm's propensity to employ share repurchases. Firms with higher levels of or greater increases in insider ownership prefer stock repurchases to cash dividends. This relation is more significant in years when dividends were more tax disadvantaged relative to capital gains. Our findings are robust to the endogeneity of insider ownership and the inclusion of various control variables such as firm size, permanence of cash flows, growth opportunities, institutional ownership, and executive stock options. Overall, our results suggest that personal tax considerations from insiders affect corporate payout decisions.

In this paper we present a new method of approximating the risk neutral density (RND) from option prices based on the C-type Gram-Charlier series expansion (GCSE) of a probability density function. The exponential form of this type of GCSE guarantees that it will always give positive values of the risk neutral probabilities, and it can allow for stronger deviations from normality, which are two drawbacks of the A-type GCSE used in practice. To evaluate the performance of the suggested expansion of the RND, the paper presents simulation and empirical evidence.

In textbook models of exchange rate determination, the news contained in public information announcements is directly impounded into prices with there being no role for trading in this process of information assimilation. This paper directly tests this theoretical result using transaction level exchange rate return and trading data and a sample of scheduled macroeconomic announcements. The main result of the paper is that even information that is publicly and simultaneously released to all market participants is partially impounded into prices via the key micro level price determinant—order flow. We quantify the role that order flow plays and find that approximately one third of price-relevant information is incorporated via the trading process.

Tests for the existence and the sign of the volatility risk premium are often based on expected option hedging errors. When the hedge is performed under the ideal conditions of continuous trading and correct model specification, the sign of the premium is the same as the sign of the mean hedging error for a large class of models. We show that discrete trading and model misspecification may cause the standard test to yield unreliable results. In particular, ignoring jump risk premia can lead to incorrect conclusions. We also show that delta-gamma hedges do not increase the reliability of the test.

Fund managers' bias toward geographically proximate securities is a well-researched phenomenon, yet the origins of managers' location choices have received little empirical scrutiny. This paper traces the employment and geographic heritage of 358 entrepreneurial fund managers and analyzes the determinants of where they locate their firms and stock selections. The evidence suggests that start-ups tend to be based close to the origins of their founders and in regions with more investment management firms, banking establishments, and large institutional money managers. New money managers show a strong local bias in their equity holdings, three times the levels previously documented for mutual funds. The propensity to invest closer to home correlates strongly with the presence of sub-advisory opportunities from institutional investors in the vicinity. While home bias levels between managers who relocate with their start-ups and the rest of the entrepreneurs are similar, preferences for stocks that were formally local persist.

To the extent that investors diversify internationally, large-cap stocks receive the dominant share of fund allocation. Increasingly, however, returns to large-cap stocks or stock market indices tend to comove, mitigating the benefits from international diversification. In contrast, stocks of locally oriented, small companies do not exhibit the same tendency. In this paper, we assess the potential of small-cap stocks as a vehicle for international portfolio diversification during the period 1980–1999. We show that the extra gains from the augmented diversification with small-cap funds are statistically significant for both in-sample and out-of-sample periods and remain robust to the consideration of market frictions.

A number of recent studies finds two asymmetries in dependence structures in international equity markets; specifically, dependence tends to be high in both highly volatile markets and in bear markets. In this paper, a further investigation of asymmetric dependence structures in international equity markets is performed by using the Markov switching model and copula theory. Combining these two theories enables me to model dependence structures with sufficient flexibility. Using this flexible framework, I indeed find that there are two distinct regimes in the U. S.-U. K. market. I also show that for the U. S.-U. K. market the bear regime is better described by an asymmetric copula with lower tail dependence with clear rejection of the Markov switching multivariate normal model. In addition, I show that ignorance of this further asymmetry in bear markets is very costly for risk management. Lastly, I conduct a similar analysis for other G7 countries, where I find other cases in which the use of a Markov switching multivariate normal model would be inappropriate.

Starting from the reward-risk model for portfolio selection introduced in De Giorgi (2005), we derive the reward-risk Capital Asset Pricing Model (CAPM) analogously to the classical mean-variance CAPM. In contrast to the mean-variance model, reward-risk portfolio selection arises from an axiomatic definition of reward and risk measures based on a few basic principles, including consistency with second-order stochastic dominance. With complete markets, we show that at any financial market equilibrium, reward-risk investors' optimal allocations are comonotonic and, therefore, our model reduces to a representative investor model. Moreover, the pricing kernel is an explicitly given, non-increasing function of the market portfolio return, reflecting the representative investor's risk attitude. Finally, an empirical application shows that the reward-risk CAPM captures the cross section of U.S. stock returns better than the mean-variance CAPM does.
