Knowledge that Transforms

This paper analyzes the role of financial intermediaries as marketmakers in the market for interest rate swaps. We argue that intermediaries which hold large nontraded portfolios of swaps are efficient alternatives to direct hedging by counterparties in publicly traded cash and futures instruments. The efficiency afforded by the swap marketmaker derives from reduction in transactions costs, diversification of basis risk, and reduced agency costs of debt. The analysis provides an explanation for the existence and success of the swaps market as a means for spreading risk and for its dominance by large financial institutions.

The traditional structure-conduct-performance (SCP) hypothesis relates concentration and the mean level of prices but ignores the dispersion of prices around their mean levels. This paper tests two hypotheses which are capable of explaining both the mean and the dispersion of elements in the pricing vector of retail banks—a concentration/collusion-based hypothesis and an asymmetric information-based hypothesis. Evidence is found that the dispersion of bank fees across banks may be due to both market structure and information reasons. The level of bank fees appears to be generally insignificantly related to concentration.

We frequently observe that contracts do not include all of the contingencies that would seem to be necessary for optimal risk sharing between the parties to the contract. One reason may be that the possibility of renegotiation makes the contract more contingent than it appears. A simple contracting problem is used to show how even a simple contract may achieve optimal risk sharing if new information arrives slowly relatively to the speed of renegotiation.

This paper examines whether middle age American households purchase adequate amounts of life insurance. The analysis is based on SRI International's 1980, 1982, and 1984 surveys of the financial positions of American households. Our findings indicate that a significant minority of American wives are highly underinsured with respect to the possible deaths of their husbands. We find that 25 to 30% of wives are inadequately insured, by which we mean that they would suffer a loss in their rate of sustainable consumption of at least 30% in the event of being widowed. These findings on inadequate life insurance are even more striking if one focuses on those households in which over half of the couple's present expected value of resources is dependent on the husband's survival. The results of this paper together with those of the related literature strongly suggest that raising the share of social security benefits that are paid to surviving spouses as well as increasing employer-provided group life insurance could have a very considerable impact on the alleviation of poverty among widows, especially elderly widows.

This paper uses firm-level panel data to investigate the proposition that reliquification is an important phase of the business cycle. It occurs late during recessions and is characterized by prolonged reductions in real investment, caused by firms needing to accumulate assets in order to improve their financial health. The paper concludes that a buildup of assets precedes an increase in investment. This effect is more important for firms without access to organized bond markets and during recession years.

This paper tests the hypothesis that the football betting market is efficient. Our statistical tests are stronger than those in previous studies, and we examine both NFL and college data over a sample period of fifteen years. Our statistical tests detect two specific biases in the NFL market and an unspecified bias in the college market. We examine the year-to-year consistency and magnitudes of the biases and find that the NFL bias against home teams has been nearly eliminated, while the bias against underdogs has increased. Profitable exploitation of the biases depends upon transaction costs.

In this paper, we present a simple model which relates security returns to three components: an expected return, a bid-ask error, and white noise. The relative importance of the various components is empirically assessed, and the model's ability to explain the various time-series properties of individual security and portfolio returns is tested. Time-varying expected returns and bid-ask errors are found to explain substantial proportions (up to 24%) of the variance of security returns. We also reconcile the typically negative autocorrelation in security returns with the strong positive autocorrelation in portfolio returns.

We develop a measure of free cash flow using Tobin's q to distinguish between firms that have good investment opportunities and those that do not. In a sample of successful tender offers, bidder returns are significantly negatively related to cash flow for low q bidders but not for high q bidders; further, the relation between cash flow and bidder returns differs significantly for low q and high q bidders. This result holds for several cash flow measures suggested in the literature and also in multivariate regressions controlling for bidder and contest-specific characteristics.

This paper analyzes the SEC's proxy regulations and assesses their effects on corporate governance. The proxy rules began in 1935 as a minimal series of disclosure requirements and a prohibition against fraud. By 1956, they imposed extensive and wide-ranging disclosure requirements on anyone wishing to communicate about voting issues and required that all such communications be cleared in advance — in essence, censored — by the SEC. I present evidence that since that time, the rules have significantly increased the costs of communication and coordinated action among shareholders. They have thus deterred shareholder initiatives and inhibited the development of a private market for information about voting issues.

Many authors have identified the hazards of ignoring event-induced variance in event studies. To determine the practical extent of the problem, we simulate an event with stochastic effects. We find that when an event causes even minor increases in variance, the most commonly-used methods reject the null hypothesis of zero average abnormal return too frequently when it is true, although they are reasonably powerful when it is false. We demonstrate that a simple adjustment to the cross-sectional techniques produces appropriate rejection rates when the null is true and equally powerful tests when it is false.
