Exit as Governance: An Empirical Analysis

Recent theory posits a new governance channel available to blockholders: threat of exit. Threat of exit, as opposed to actual exit, is difficult to measure directly. However, a crucial property is that it is weaker when stock liquidity is lower and vice versa. We use natural experiments of financial crises and decimalization as exogenous shocks to stock liquidity. Firms with larger blockholdings experience greater declines (increases) in firm value during the crises (decimalization), particularly if the managers wealth is sensitive to the stock price and thus to exit threats. Additional tests suggest exit threats are distinct from blockholder intervention.

Liquidity Risk of Corporate Bond Returns: A Conditional Approach

We study the exposure of the U.S. corporate bond returns to liquidity shocks of stocks and treasury bonds over the period 1973-2007 in a regime switching model. In one regime, liquidity shocks have mostly insignificant effect on bond prices, whereas in another regime, a rise in illiquidity produces significant but conflicting effects: Prices of investment-grade bonds rise while prices of speculative grade (junk) bonds fall substantially (relative to the market). Relating the probability of these regimes to macroeconomic conditions we find that the second regime can be predicted by economic conditions that are characterized as “stress.�? These effects, which are robust to controlling for other systematic risks (term and default), suggest the existence of time-varying liquidity risk of corporate bond returns conditional on episodes of flight to liquidity. Our model can predict the out-of-sample bond returns for the stress years 2008-2009. We find a similar pattern for stocks classified by high or low book-to-market ratio, where again liquidity shocks play a special role in periods characterized by adverse economic conditions.

Credit ratings and the BIS capital adequacy reform agenda

Abstract In this paper, we have revised and updated our earlier study in order to analyze the most recent (second) draft of the BISs proposed reforms of bank capital requirements. We conduct Monte-Carlo experiments using data on defaults and severity rates on publicly-traded US corporate bonds over the 1981–1999 period. Analyzing the whole period and various sub-periods, it is clear that the most recent draft of the BIS proposed reforms seriously overestimates the relative riskiness of high-quality debt relative to low quality debt in the so-called standardized model. As a result, the most recent proposal still contains inherent risk-shifting (taking) incentives for banks.

Are Women Executives Disadvantaged

We investigate gender differences in insider trading behavior of senior corporate executives in the U.S. between 1975 and 2005. We find that, on average, both female and male executives make positive profits from insider trading, but males earn about twice as much as females; males also trade more than females. All these results also hold for the sub sample of very top executives. We are able to rule out gender differences in overconfidence and risk-aversion as sole explanations for our results. The results are consistent with the view that female executives have a disadvantage relative to males in accessing inside information

Does Capital Market Myopia Affect Plant Productivity? Evidence from Going Private Transactions

One influential criticism of the stock market oriented U.S. financial system is that its excessive focus on short term quarterly earnings forces public firms to behave in a myopic manner. We hypothesize that if capital markets pressure listed firms to be myopic in a way that impacts efficiency, then going private (when myopia is eliminated) should cause U.S. firms to improve their establishment level productivity relative to a peer control groups of firms. We find no evidence that this is the case. Our key finding is that while there is evidence for substantial within-establishment increases in productivity after going private, there is little evidence of difference-in-differences efficiency gains relative to peer groups of establishments constructed to control for industry, age, size at the time of going private, and the endogeneity of the going private decision effects. Also, we do not find evidence that myopic markets lead to under-investment at the establishment level. On the contrary, we find that after going private, firms shrink capital and employment, and close plants more quickly, relative to peer groups. Our findings cast doubt on the view that public markets cause listed firms to make sub-optimal, productivity-decreasing choices, or under-invest at the establishment level.

External Governance and Debt Structure

This paper examines how external governance pressure provided by both the product market and the market for corporate control affects the type of debt that firms issue. Consistent with a governance substitution effect, we find that (i) an exogenous increase in governance pressure from the product market has a significant negative impact on the use of bank financing over public debt issuance, and (ii) an exogenous decrease in governance pressure from the takeover market has a significant positive impact on the use of bank financing. Tests using changes in the strictness of loan covenants provides corroborative evidence. Also consistent with bank specialness in providing governance, we find that a bank loan issue causally increases total factor productivity of firms by 1% to 1.6% per year over a bond issue for up to four years after the issuance. We interpret these findings as consistent with the notion that firms endogenously substitute among alternative governance mechanisms in devising a governance structure that allows external capital to be raised at the lowest possible cost and that demand for creditor governance depends on the relative strength of alternative external governance mechanisms.

Corporate Governance and Loan Syndicate Structure

Firms with greater shareholder rights have higher risk-shifting incentives. Such firms should have more concentrated loan syndicates to ensure more intensive monitoring. In the United States, the second generation antitakeover laws reduced the shareholder rights significantly. We find that loan syndicates became significantly less concentrated after the passage of these laws. Our results are robust to legal, institutional and political economy considerations that affect these tests. Additional tests support the risk-shifting channel. Our results have important implications for understanding how corporate governance causally affects financial contracting and creditor control in firms.
