Theory suggests that economic instruments, such as pollution taxes or tradable permits, can provide more efficient technology adoption incentives than conventional regulatory standards. We explore this issue for an important industry undergoing dramatic decreases in allowed pollution – the U.S. petroleum industry's phasedown of lead in gasoline. Using a duration model applied to a panel of refineries from 1971–1995, we find that the pattern of technology adoption is consistent with an economic response to market incentives, plant characteristics, and alternative policies. Importantly, evidence suggests that the tradable permit system used during the phasedown provided incentives for more efficient technology adoption decisions. 相似文献

In this study we examine the association among confirming management forecasts, stock prices, and analyst expectations. Confirming management forecasts are voluntary disclosures by management that corroborate existing market expectations about future earnings. This study provides evidence that these voluntary disclosures affect stock prices and the dispersion of analyst expectations. Specifically, we find that the market's reaction to confirming forecasts is significantly positive, indicating that benefits accrue to firms that disclose such forecasts. In addition, although we find no significant change in the mean consensus forecasts (a proxy for earnings expectations) around the confirming forecast date, evidence indicates a significant reduction in the mean and median consensus analyst dispersion (a proxy for earnings uncertainty). Finally, we document a positive association between the reduction of dispersion of analysts' forecasts and the magnitude of the stock market response. Overall, the evidence suggests that confirming forecasts reduce uncertainty about future earnings and that investors price this reduction of uncertainty. 相似文献

This article examines price behavior in the U.S. Treasury bond futures market in the mornings after large overnight price moves, using data from 1980 to 1987. The article tests whether price behavior is affected by proximity to a price limit, and whether the effect is a magnet effect or a calming effect. In that period, the price tends to reverse direction after the morning open, and the reversal appears to reflect a calming effect of the price being close to the limit. An alternative hypothesis—that morning price behavior reflects the overnight price change rather than proximity to the price limit per se—is also tested, and does not perform as well in explaining price behavior. 相似文献

The study examines insider ownership in large and small firms in relation to market efficiency. Recent studies have found a positive and significant relation between inside ownership and stock market performance. Such a finding is predicated upon the idea that inside ownership minimizes agency costs caused by the conflict between hired managers and shareholders. It is argued here that semi-strong form market efficiency requires that all public information, including insider ownership, be quickly impounded into the price of a stock. If that is the case, the expected present value of a change in agency cost should be incorporated into the stock price shortly after any significant change in ownership. Hence, if the estimate is unbiased, the longer-term performance of firms should not be effected by such changes. The issue is examined for both large, well-known firms and for smaller, less-known firms. The hypothesis that markets are generally efficient with respect to insider ownership information is rejected. 相似文献

In this paper we investigate the efficiency of a class of transaction-generating algorithms, originally suggested in Bollerslev and Domowitz (1993). Our comparison utilizes real transaction data recorded over Reuters D2000-2 electronic broking system for 7 h in June 1993 and transaction data generated from FXFX quotations over an identical period. Results suggest that, at this high-frequency data sampling, the performance of these transaction-generating algorithms is poor, with the most likely explanation of this outcome due to the high-frequency characteristics of FXFX spreads and quotation intensity. 相似文献

Estimates of central bank intervention losses or profits vary widely; some estimates find substantial losses, others profits. In most cases, estimated profits are not risk-adjusted, and risk adjustment can have large effects. Furthermore, profit estimates involve variables integrated of order one, and because of this test-statistics may have nonstandard distributions; few studies take this into account. Estimates of risk-adjusted profits for the US Fed and the Swedish Riksbank, with allowances for possible nonstandard distributions, suggest that neither made losses and might have made significant profits. 相似文献

Correlation estimates for returns between individual properties are subject to large inherent uncertainties due to limits on the amount of data that is likely to be available for the foreseeable future. After allowance for correlation sampling error, it is impossible to distinguish on an ex ante basis between the risk-reduction capabilities of mean-variance portfolio selection models and naive diversification without regard to property type or geographical location. The naive portfolio diversification strategies of typical institutional real estate portfolio managers are rational responses to limitations on the informational content of statistical analyses of historical real estate data. 相似文献

Longevity Bonds: Financial Engineering, Valuation, and Hedging 总被引:2,自引:0,他引:2

This article examines the main characteristics of longevity bonds (LBs) and shows that they can take a large variety of forms which can vary enormously in their sensitivities to longevity shocks. We examine different ways of financially engineering LBs and consider problems arising from the dearth of ultra‐long government bonds and the choice of the reference population index. The article also looks at valuation issues in an incomplete markets context and finishes with an examination of how LBs can be used as a risk management tool for hedging longevity risks. 相似文献

This paper analyses the time series behaviour of the initial public offering (IPO) market using an equilibrium model of demand and supply that incorporates the number of new issues, average underpricing, and general market conditions. Model predictions include the existence of serial correlation in both the number of new issues and the average level of underpricing, as well as interactions between these variables and the impact of general market conditions. The model is tested using 40 years of monthly IPO data. The empirical results are generally consistent with predictions. 相似文献
