We use the 2003 NYSE and NASDAQ listing rules for board and committee independence as a quasinatural experiment to examine the causal relations between board structure and CEO monitoring. Noncompliant firms forced to raise board independence or adopt a fully independent nominating committee significantly increased their forced CEO turnover sensitivity to performance relative to compliant firms. Nominating committee independence is important even when firms had an independent board, and the effect is stronger when the CEO is on the committee. We conclude that greater board independence and full independence of nominating committees lead to more rigorous CEO monitoring and discipline.

Evaluating agency theory and optimal contracting theory views of corporate philanthropy, we find that as corporate giving increases, shareholders reduce their valuation of firm cash holdings. Dividend increases following the 2003 Tax Reform Act are associated with reduced corporate giving. Using a natural experiment, we find that corporate giving is positively (negatively) associated with CEO charity preferences (CEO shareholdings and corporate governance quality). Evidence from CEO-affiliated charity donations, market reactions to insider-affiliated donations, its relation to CEO compensation, and firm contributions to director-affiliated charities indicates that corporate donations advance CEO interests and suggests misuses of corporate resources that reduce firm value.

[This study examines the impact of competition on bid-ask spreads in the spot foreign exchange market. We measure competition primarily by the number of dealers active in the market and find that bid-ask spreads decrease with an increase in competition, even after controlling for the effects of volatility. The expected level of competition is time varying, highly predictable, and displays a strong seasonal component that in part is induced by geographic concentration of business activity over the 24-hour trading day. Our estimates show that the expected addition of one more competing dealer lowers the average quoted spread by 1.7%.]

This study analyzes both the causes and effects of mutual S&L conversions to corporate charter. Changes in technology and government policies have substantially increased S&L competition, riskbearing, and potential scale and scope economies. Evidence indicates that these changes have decreased the relative operating advantages of mutual S&Ls, encouraging conversions to stock charter. The S&L's financial and operating characteristics, which affect the success of the conversion effort, are also explored.

This study considers the impact of capital structure change announcements on security prices. Statistically significant price adjustments in firms' common stock, preferred stock and debt related to these announcements are documented and alternative causes for these price changes are examined. The evidence is consistent with both corporate tax and wealth redistribution effects. There is also evidence that firms make decisions which do not maximize stockholder wealth. In addition, a new approach to testing the significance of public announcements on security returns is presented.

[We study a widespread yet under-explored corporate governance phenomenon: the pledging of company stock by insiders as collateral for personal bank loans. Utilizing a regulatory change that exogenously decreases pledging, we document a negative causal impact of pledging on shareholder wealth. We study two channels that could explain this effect. First, we find that margin calls triggered by severe price falls exacerbate the crash risk of pledging firms. Second, since margin calls may cause insiders to suffer personal liquidity shocks or to forgo private benefits of control, we hypothesize and find that pledging is associated with reduced firm risk-taking.]

[Empirical evidence on the relations between board independence and board decisions and firm performance is generally confounded by serious endogeneity issues. We circumvent these endogeneity problems by demonstrating the strong impact of the local director labor market on board composition. Specifically, we show that proximity to larger pools of local director talent leads to more independent boards for all but the largest quartile of S&P 1500. Using local director pools as an instrument for board independence, we document that board independence has a positive effect on firm value, operating performance, fraction of CEO incentive-based pay, and CEO turnover.]

[The short-run interdependence of prices and price volatility across three major international stock markets is studied. Daily opening and closing prices of major stock indexes for the Tokyo, London, and New York stock markets are examined. The analysis utilizes the autoregressive conditionally heteroskedastic (ARCH) family of statistical models to explore these pricing relationships. Evidence of price volatility spillovers from New York to Tokyo, London to Tokyo, and New York to London is observed, but no price volatility spillover effects in other directions are found for the pre-October 1987 period.]

We analyze financial contracting in start-ups backed by corporate venture capitalists (CVCs). CVCs' strategic goals can economically hurt or benefit the start-ups, depending on product market relationships between start-ups and CVC parents. Empirically, start-ups receive funding from both complementary and competitive CVC parents. However, start-up insiders commonly limit the influence of competitive CVCs, awarding them lower board power, while retaining higher board representation for themselves. Second, lead CVCs receive lower board representation, indicating heightened concerns about their greater influence in start-ups' early stages. Finally, start-ups extract higher valuations from competitive CVCs, reflecting greater moral hazard problems. Overall, CVC strategic objectives affect their early inclusion in VC syndicates, their control rights and share pricing.

[Using a dataset of 28,635 firms in 45 countries, this study investigates the motivations for family-controlled business groups. We provide new evidence consistent with the argument that particular group structures emerge not only to perpetuate control, but also to alleviate financing constraints at the country and firm levels. At the country level, family groups, especially those structured as pyramids, are more prevalent in markets with limited availability of capital. At the firm level, investment intensity is greater for firms held in pyramidal rather than in horizontal structures, reflecting the financing advantages of the former. Within a pyramid, internal equity funding, investment intensity, and firm value all increase down the ownership chain. However, group firm performance declines when dual-class shares and cross shareholdings are employed as additional control-enhancing mechanisms.]
