This study examines whether the uncertainty arising from a firm's exposure to future environmental costs (environmental uncertainty) affects the market's price sensitivity to reported earnings. Specifically, when environmental uncertainty is significantly high, are investors more responsive to reported earnings released by 'high-polluting' firms than reported earnings announced by 'low-polluting' firms within the same industry? The initial impact of Title IV (the acid rain provisions) of the 1990 Clean Air Act Amendments (1990 CAAA) on the US electric utility industry provides the research setting required to isolate the effects of environmental uncertainty while addressing this question. Consistent with theoretical predictions, we find that the earnings response coefficients (ERCs) of high-polluting electric utilities are significantly greater than those of their low-polluting counterparts during a predicted period of elevated environmental uncertainty. In adjoining sample years associated with lower environmental uncertainty, we observe no statistical difference in the magnitude of the ERCs between these two groups. In addition, the study's findings suggest that the magnitude of the ERC is increasing in the firm's exposure to future environmental costs, after controlling for other factors that potentially affect ERCs.  相似文献

In this paper, we examine the impact of managerial self-interest on the value of multinationality. Since agency theory also suggests that a divergence between the interests of managers and shareholders can be aligned by effective managerial incentive, we also examine the effect of managerial compensation on the value of multinationality. Our results show that for high- Q (Tobin's Q > 1 ) firms, investors do not associate the spending of free cash flow on multinationality with the problem of overinvestments. For high- Q firms, it is also found that the value of multinationality can be enhanced by effective managerial incentives. For low- Q firms (Tobin's Q < 1 ), it is found that the concern of managerial self-interest overwhelms the benefits of internalization, making multinationality a value-decreasing event. For low- Q firms, managerial compensation is also ineffective in promoting value-enhancing foreign direct investments.  相似文献

Initial margin requirements represent: (1) a cost impediment to the wealth constrained investor and (2) a potential way of mitigating excessive volatility. However, prior empirical research finds that margins are not an effective tool in reducing volatility. We consider the possibility that margins primarily affect certain stocks and investors. Specifically, we test whether margins affect individuals who, as a group, we believe to be the investors most affected when margin requirements change. Our initial empirical tests, however, do not support this contention.  相似文献

Rural roads promote economic development, but they also facilitatedeforestation. To explore this tradeoff, this article developsa spatially explicit model of land use and estimates probabilitiesof alternative land uses as a function of land characteristicsand distance to market using a multinomial logit specificationof this model. Controls are incorporated for the endogeneityof road placement. The model is applied to data for southern Belize, an area experiencingrapid expansion of both subsistence and commercial agriculture,using geographic information system (GIS) techniques to selectsample points at 1-kilometer intervals. Market access, landquality, and tenure status affect the probability of agriculturalland use synergistically, having differential effects on thelikelihood of commercial versus semisubsistence farming. Theresults suggest that road building in areas with agriculturallypoor soils and low population densities may be a \"lose-lose\"proposition, causing habitat fragmentation and providing loweconomic returns.  相似文献

This paper extends the work by Morris and Shin (Am. Econom. Rev. 88 (1998) 587-597) where multiple equilibria in the self-fulfilling currency attack models can be reduced to a unique equilibrium when agents observe fundamentals privately with small errors. We find that under a more general specification with realistic parameters, noisy private observations are generally insufficient to prevent the multiplicity of equilibria. The pivotal role played by the transparency of fundamentals/policies in currency crisis is also examined. Surprisingly, transparency may trigger rather than eliminate currency crises when fundamentals are relatively healthy. Our results may be relevant to research in other coordination problems.  相似文献

In both economic and military situations, agents may try to mislead rivals about their true types or plans, whatever they may be. We consider a simple model in which one player attacks and the other player defends. We show that such environments have two types of possible equilibrium behavior, depending upon the signaling technology. If the signal is not very revealing about the attacker's plans, then the attacker always invests more resources in attack than in misdirection. If the technology is revealing, then the attacker does not always feint, but when he feints, he invests more than half of his resources into misdirection. Comparative statics also depend on whether the technology is revealing.
