Market Reaction to Regulatory Action in the Insurance Industry: The Case of Contingent Commission

We examine the market's reaction to New York Attorney General Eliot Spitzer's civil suit against mega‐broker Marsh for bid rigging and inappropriate use of contingent commissions within a generalized autoregressive conditionally heteroskedastic (GARCH) framework. Effects on the stock returns of insurance brokers and insurers are tested. The findings are: (1) GARCH effects are significant in modeling broker/insurer returns; (2) the suit generated negative effects on the brokerage industry and individual brokers, suggesting that contagion dominates competitive effects; (3) spillover effects from the brokerage sector to insurance business are significant and mostly negative, demonstrating industry integration; and (4) information‐based contagion is supported, as opposed to the pure‐panic contagion.     

Market Response to Liquidity Improvements: Evidence from Exchange Listings

The study examines a sample of 895 stocks that moved from Nasdaq to the New York Stock Exchange or to the American Stock Exchange (Amex) between 1971 and 1994. We show how various measures of liquidity such as the bid‐ask spread, trading volume, and stock price precision improve in somewhat different ways upon transfer to NYSE (Amex). We also find that reductions in trading costs (percentage spread) and in pricing error volatility (Hasbrouck's σ₅) can explain most of stock market's positive response to exchange listing. Thus, liquidity has many facets and cannot be represented by the bid‐ask spread alone.     

Derivative Exposure and the Interest Rate and Exchange Rate Risks of U.S. Banks

This article estimates the interest rate and exchange rate risk betas of 59 large U.S. commercial banks for the period of 1975–1992, as well as the bank-specific determinants of these betas. The estimation procedure uses a modified seemingly unrelated simultaneous method that recognizes cross-equation dependencies and adjusts for serial correlation and heteroskedasticity. Overall, the exchange rate risk betas are more significant than the interest rate risk betas. More importantly, we find a link between the scale of a bank's interest rate and currency derivative contracts and the bank's interest rate and exchange rate risks. Particularly noteworthy is the influence of currency derivatives on exchange rate betas.     

Institutional ownership stability and the cost of debt

This study documents that the stability of institutional ownership plays an important role in determining the cost of debt. After controlling for other determinants of the cost of debt, and correcting for the endogeneity of institutional ownership stability, three major results are uncovered. First, there is a robust negative relationship between the cost of debt and institutional ownership stability. Second, institutional ownership stability plays a bigger role in determining the cost of debt, than the institutional ownership level commonly used in the literature. Third, institutional ownership stability affects the cost of debt to a greater extent for firms that are subject to more severe information asymmetry and greater agency costs of debt.     

Performance persistence of closed-end funds

Studies of performance persistence of closed-end funds (CEFs) use two measures of persistence; autocorrelation and rank correlation of performance. The autocorrelation measure offers limited information because it cannot separate persistence relative to the market and to the industry. The rank correlation measure is generally applied to two periods, disregarding multi-period persistence. We investigate performance persistence of CEFs in terms of both market price return and net asset value return using contingency tables and multiple regression models. Jensen’s alpha and the Sharpe ratio are used as measures of risk-adjusted performance. We test three hypotheses: (i) CEFs performing better than the industry median will do so persistently, (ii) CEFs outperform the market persistently; and (iii) performance persistence can be partly explained by dividend yield. The findings are fivefold. First, the number of persistent years varies with the models used to calculate risk-adjusted performance. Second, with 4-index unconditional beta fixed variance model, CEFs persistently beat their industry for six out of 10 years in terms of both market price return and net asset value return. Third, with a 4-index unconditional beta fixed variance model, we find performance persistence relative to market for 6 and 7 years, out of the 10 years considered, in terms of market price return and net asset value return, respectively. Fourth, the disaggregate sample tests show that performance of municipal bond funds is more persistent than equity funds and taxable bond funds. Fifth, dividend patterns can partially explain persistence with liquidity as control.     

Reference Data Models for the Strategic Controlling of Waste Management Firms

The paper depicts the development of reference data models for strategic key performance indicator systems specific to waste management firms providing a new comprehensive typology of generic models for data warehouse solutions. Additionally, a development methodology for industry solutions is applied, which, given the empirically founded typification process and the theoretically derived performance measurement systems, is characterized by a high degree of structure and transparency. The new approach thus systematically integrates both inductive-empirical and deductive-analytical elements.     

Bank stability and managerial compensation

We investigate the relationship between insolvency risk and executive compensation for BHCs over the 1992–2008 period. We employ CEO compensation sensitivity to risk (vega) and pay-share inequality between the CEO and other executives as measures of compensation and employ a system model to account for the endogeneity problem between vega and risk. Five main results are obtained. First, CEO compensation sensitivity to risk of BHCs has risen in response to deregulation to resemble those of the industrial firms. Second, higher vegas lead to greater bank instability. Third, the association between bank stability and managerial compensation is bi-directional; higher vegas induce greater risk and vice versa. Fourth, BHCs in the next to the largest-size group increase CEO vegas the most and have the strongest potential to create instability. Fifth, increased pay-share inequality has effects opposite to those of the increase in vega; greater pay-share inequality is associated with greater stability.     

NONNESTED PROCEDURES IN ECONOMETRIC TESTS OF ASSET PRICING THEORIES

In this paper nonnested tests are used to contrast the performance of the capital asset pricing (CAPM) and consumption capital asset pricing (CCAPM) theories in describing the U.S. stock market. The procedures employed include the N‐test, the NT‐test, the W‐test, the J‐test, and the Encompassing test. The tests are carried out using data on firms as well as portfolios based on beta, capitalization, and Standard Industrial Classification codes. The findings indicate that although during 1973–82 the CAPM dominates the CCAPM, during 1978–87 the results are mixed, and during 1983–92 the CCAPM dominates. The finding in favor of the CCAPM in 1983–92 conflicts with much of the existing literature, which favors the CAPM.     

A nonparametric approach to measurement of efficiency and technological change: The case of large U.S. commercial banks

The purpose of this paper is to derive the efficiency measures and the rate of technological change for a sample of large U.S. commercial banks by employing a nonparametric technique. This technique is used to construct a multiproduct production frontier relative to which the efficiency measures of the banks in the sample are calculated and the displacement of which over time provides a measure of the rate of technological change. The empirical results indicate that the relevant frontier shifted inward between 1980 and 1985 reflecting a high pace of technological advancement achieved by the banks in the sample. The pace varied significantly across the banks with some banks even regressing over time.     

The Determinants of Debt Maturity at Issuance: A System-Based Model

We examine the determinants of corporate debt maturity while taking into account the interdependent relation between maturity and leverage. We do this by estimating a simultaneous-equations model on debt maturity and leverage for a sample of bond-issuing firms. To compare with previous studies, we also estimate a single-equation model on debt maturity using OLS. We define debt maturity as either the maturity of bonds at issuance (incremental approach), or the percentage of a firm's total debt that matures in more than three years (balance-sheet approach). Corroborating the findings of many previous studies, our single-equation OLS results support the underinvestment hypothesis purporting that firms with greater growth opportunities have shorter-term debt. However, under the simultaneous-equations model, the negative relation between a firm's debt maturity and its growth opportunities ceases to hold. Instead, it is the leverage decision that is influenced by growth opportunities. This suggests that existing models may overestimate the effect of growth opportunities on debt maturity.
