Knowledge that Transforms

Posttakeover moral hazard by the acquirer and free‐riding by the target shareholders lead the former to acquire as few sharcs as necessary to gain control. As moral hazard is most severe under such low ownership concentration, inefficiencies arise in successful takeovers. Moreover, share supply is shown to be upward‐sloping. Rules promoting ownership concentration limit both agency costs and the occurrence of takeovers. Furthermore, higher takeover premia induced by competition translate into higher ownership concen‐tration and are thus beneficial. Finally, one share‐one vote and simple majority are generally not optimal, and socially optimal rules need not emerge through private contracting.

The anomaly is concerned with the observation that in multiple item auctions of identical objects, prices tend to decline over time. I show that in the case of wine auctions, which have been analyzed frequently, the anomaly is likely to be caused by the fact that most bids are entered by absentees, who use nonoptimal bidding strategies. Therefore, wine auctions can hardly be used to illustrate the standard multiple‐object auction model.

Over last two decades punitiveness of juvenile justice system has declined substantially relative adult courts. During that same time period juvenile violent rates have grown almost twice as quickly as adult crime rates. This paper examines degree to which those two empirical observations are related, finding that changes in relative punishments can account for 60 percent of differential growth rates in juvenile and adult violent between 1978 and 1993. Juvenile offenders appear be at least as responsive sanctions as adults. Moreover, sharp changes in criminal involvement with transition from juvenile adult court suggest that deterrence, rather than simply incapacitation important role. There does not, however, appear be a strong relationship between the punitiveness of juvenile justice system that a cohort faces and extent of involvement for that cohort later in life.

As pointed out by Hall (1988), intertemporal substitution by consumers is a central element of many modern macroeconomic and international models. We argue that Hall's estimator or the IES is downward biased because the intra-temporal substitution between nondurable consumption goods and durable consumption goods is ignored and because the changes in real interest rates affect user costs of durable goods.

There exists a positive correlation between an economy's exposure to international trade and the size of its government. The correlation holds for most measures of government spending, in low- as well as high-income samples, and is robust to the inclusion of a wide range of controls. One explanation is that government spending plays a risk-reducing role in economies exposed to a significant amount of external risk. The paper provides a range of evidence consistent with this hypothesis. In particular, the relationship between openness and government size is strongest when terms-of-trade risk is highest.

We study the effects of changes in bid–ask spreads on the prices and trading volumes of stocks that move from Nasdaq to the NYSE or Amex and stocks that move from Amex to Nasdaq. When stocks move from Nasdaq to an exchange, their spreads typically decrease, but the reduction in spreads is larger when Nasdaq market makers avoid odd-eighth quotes. When stocks move from Amex to Nasdaq, their spreads typically increase, but again, the increase is larger when Nasdaq market makers avoid odd eighths. We use this data to isolate the effects of transaction costs on trading volume and expected returns. We find that higher transaction costs significantly reduce trading volume, but do not have a significant effect on prices.Journal of Economic LiteratureClassification Numbers: G10, G14.

This paper proposes and implements a security design framework to assess why corporate managers issue convertible debt. We examine three theories that make predictions about the design of convertible debt. Our results suggest that some issuers design convertible debt to mitigate asset substitution problems, while others design it to reduce adverse selection problems. We also find that issuers vary convertible debt security design over the business cycle in response to time variation in asset substitution and adverse selection problems. Overall, the results indicate that corporate managers actively alter convertible debt security design to mitigate costly external finance problems.

We develop a model to examine the impact of international cross-listing on domestic market liquidity and trading volume to determine when domestic market development is likely to follow. Greater information transparency between markets increases domestic market liquidity and volume, resulting in market development. Conversely, post-listing order flow migration away from the domestic market reduces its liquidity and volume, resulting in retardation. The net impact is positive and greater when market professionals acquire rather than reveal information, for smaller previously restricted markets, and for cross-listings in larger more transparent markets that have a greater potential to expand the shareholder base.Journal of Economic LiteratureClassification Numbers: D44, D82, F36, G15.

We present evidence that insured deposit financing shields banks from the full costs of market discipline. Moody's downgrades, indicators of increasing risk, are associated with negative abnormal equity returns that are increasing in the bank's reliance on insured deposits. Moreover, banks raise their use of insured deposits following increases in risk. These findings cast doubt on the ability of capital market participants to effectively discipline bank behavior within the current regulatory environment. More generally, our findings highlight the potential for regulation to undermine market discipline in regulated industries.

Previous research finds the volatility implied by S&P 100 index option prices to be a biased and inefficient forecast of future volatility and to contain little or no incremental information beyond that in past realized volatility. In contrast, we find that implied volatility outperforms past volatility in forecasting future volatility and even subsumes the information content of past volatility in some of our specifications. Our results differ from previous studies because we use longer time series and nonoverlapping data. A regime shift around the October 1987 crash explains why implied volatility is more biased in previous work.
