We provide evidence that firms with more transparent earnings enjoy a lower cost of capital. We base our earnings transparency measure on the extent to which earnings and change in earnings covary contemporaneously with returns. We find a significant negative relation between our transparency measure and subsequent excess and portfolio mean returns, and expected cost of capital, even after controlling for previously documented determinants of cost of capital. 相似文献

Standard & Poor's Depositary Receipts (SPDRs) are exchange traded securities representing a portfolio of S&P 500 stocks. They allow investors to track the spot portfolio and better engage in index arbitrage. We tested the impact of the introduction of SPDRs on the efficiency of the S&P 500 index market. Ex‐post pricing efficiency and ex‐ante arbitrage profit between SPDRs and futures were also examined. We found an improved efficiency in the S&P 500 index market after the start of SPDRs trading. Specifically, the frequency and length of lower boundary violations have declined since SPDRs began trading. This result is consistent with the hypothesis that SPDRs facilitate short arbitrage by simplifying the process of shorting the cash index against futures. Tests of pricing efficiency comparing SPDRs and futures suggested that index arbitrage using SPDRs as a substitute for program trading in general results in losses. Although short arbitrages earn a small profit on average, gains are statistically insignificant. A trade‐by‐trade investigation showed that prices are instantaneously corrected after the presence of mispricing signals, introducing substantial risk in arbitraging. Evidence in general supported pricing efficiency between SPDRs and the S&P 500 index futures—both ex‐post and ex‐ante. © 2002 Wiley Periodicals, Inc. Jrl Fut Mark 22:877–900, 2002 相似文献

Limit orders are usually viewed as patiently supplying liquidity. We investigate the trading of one hundred Nasdaq-listed stocks on INET, a limit order book. In contrast to the usual view, we find that over one-third of nonmarketable limit orders are cancelled within two seconds. We investigate the role these “fleeting orders” play in the market and test specific hypotheses about their uses. We find evidence consistent with dynamic trading strategies whereby traders chase market prices or search for latent liquidity. We show that fleeting orders are a relatively recent phenomenon, and suggest that they have arisen from a combination of factors that includes improved technology, an active trading culture, market fragmentation, and an increasing utilization of latent liquidity. 相似文献

At a time when choices for voice service and funding for universal service were growing, the United States experienced an unprecedented drop in household telephone penetration. Universal service in voice telephony is generally taken for granted in the United States. However, recent data from the FCC shows a significant decline in the number of U.S. households that have a telephone of any kind (including mobile), from a peak in telephone penetration of 95.5% in March 2003 down to 92.9% in November 2005. This decline is both statistically significant and meaningful, as approximately 2.6% of U.S. households could not easily reach 911 for emergencies. This study uses regression analysis of state-level data to determine what drove this decline in universal service. The results demonstrate that the recent decline in universal service in the U.S. is driven by an increase in black population, inadequate consumer protection laws, and increases in wireless telephones per capita. Lifeline effectiveness does not appear to mitigate the decline in penetration, while Link-Up effectiveness may have a limited effect. 相似文献

Despite the evolvement of an extensive literature on the economics of smuggling, the evasion of customs duties under the common red–green channel system has failed to attract any theoretical attention. The present paper develops a simple three‐passenger‐type model to examine the passenger's decision of whether to pass through the green or red channel, as well as to derive the optimal inspection policy for a revenue‐maximizing customs authority. The analysis reveals that if net revenue collection when inducing truthful declaration is positive, it is never optimal for the customs authority to provide incentives for passing through the green channel, although it may be optimal to provide incentives for cheating at the red channel. However, if the penalty for evasion is large enough to wipe out passengers' income, providing incentives for passing through the green channel may be the optimal policy. 相似文献

The harshest abusers of the unemployment insurance program are those employed who collect benefits while working. This paper analyzes fraudulent claiming behavior and optimal deterrence policy under two alternative penalty schemes, commonly used in tax evasion analyses: one relates punishment to the magnitude of the dishonesty, whereas the other relates punishment to the amount of illegal returns. Two exclusive features of fraudulent benefit claiming are given special attention: the requirement to report at a labor exchange to demonstrate availability for work, and the need to serve a waiting period before benefits can be collected. 相似文献
