The Kyoto Protocol foresees emission trading but does not yet specify verification of (uncertain) emissions. This paper analyses a setting in which parties can meet their emission targets by reducing emissions, by investing in monitoring (reducing uncertainty of emissions) or by (bilaterally) trading permits. We derive the optimality conditions and carry out various numerical simulations. Our applications suggest that including uncertainty could increase compliance costs for the USA, Japan and the European Union. Central Europe and the Former Soviet Union might be able to gain from trading due to higher permit prices. Emissions trading could also lower aggregate uncertainty on emissions. 相似文献

Free Entry under Uncertainty 总被引:1,自引:0,他引:1
When focusing on firm’s risk-aversion in industry equilibrium, the number of firms may be either larger or smaller when comparing market equilibrium with and without price uncertainty. In this paper, we introduce risk-averse firms under cost uncertainty in a model of spatial differentiation and show that the impact of uncertainty will increase the number of firms in an industry. With increased uncertainty, the risk premium of the marginal buyer increases by more than the risk premium of the average buyer, so that the price increases by more than the risk premium. When turning to the free entry game, we find that the market generates too many firms. 相似文献

We define an opportunity act as a mapping from an exogenously given objective state space to a set of lotteries over prizes, and consider preferences over opportunity acts. We allow the preferences to be possibly uncertainty averse. Our main theorem provides an axiomatization of the maxmin expected utility model. In the theorem we construct subjective states to complete the objective state space. As in E. Dekel et al. (Econometrica, in press), we obtain a unique subjective state space. We also allow for preference for flexibility in some of the subjective states and commitment in others. Journal of Economic Literature Classification Number: D81. 相似文献

Researching Preferences,Valuation and Hypothetical Bias 总被引:1,自引:0,他引:1
A number of recent papers in environmental economics have focused on the process of researching preferences – agents are uncertain
about preferences but with effort may narrow their uncertainty. This issue has arisen in formulating bids in contingent valuation
(CV) as well as the debate over the divergence between WTP and WTA. In the context of CV, it has been suggested that the hypothetical
nature of the preference elicitation process biases responses. This paper provides both a theoretical model and experimental
evidence to contribute to this debate. The model is a model of competitive bidding for a private good with two components
that are particularly relevant to the debate. The first component is that bidders are unsure of their own value for the private
good but may purchase information about their own value (researching preferences). The second component is that there is a
probability that the auction is hypothetical – that the winning bidder will not get the private good and will not pay the
winning bid. The experiment tests this theoretical model of bidding equilibrium and analyzes the effects of variations in
the parameters (hypotheticalness, information costs and number of agents) on the endogenous variables (such as the proportion
of bidders who become informed and the winning bid). Experimental results suggest that an increase in the hypotheticalness
of an auction tends to decrease the likelihood that bidders pay for information on their valuation with an ambiguous effect
on the winning bid.

In order to model the subjective uncertainty of a player over the behavior strategies of an opponent, one must consider the player's beliefs about the opponent's play at information sets that the player thinks have probability zero. This corregendum uses “trembles” to provide a definition of the convex hull of a set of behavior strategies. This corrects a definition we gave in [E. Dekel, D. Fudenberg, and D. K. Levine, 1999, J. Econ. Theory89, 165-185], which led to two of the solution concepts we defined there not having the properties we intended. Journal of Economic Literature Classification Numbers: C72, D82, C610. 相似文献

Unilateral abatement is sometimes advocated in order to set a good example that will make other countries follow. The aim
of this paper is to investigate whether existence of correlated cost uncertainty provides an incentive for a country to undertake
unilateral abatement. The theoretical model is driven by two main mechanisms; first, a learning effect, as the follower country
might reduce its risk premium as it can observe the cost level in the leader country. Second, there is the public good effect,
i.e., the marginal benefit of abatement declines when abatement is a public good and other countries contribute to pollution
reductions. Results shows that unilateral abatement would be efficient in reducing uncertainty about the unit costs of abatement
if a country with low cost uncertainty would undertake abatement first, while a country with initially high cost uncertainty
would follow. However, countries may prefer to act simultaneously because of the larger uncertainties that are inherent in
a sequential game.

对于企业家的受托责任的履行问题,国内外学者都有过相关探讨。企业家受托责任的缺失已经给企业所有者带来巨大损失,尤其是我国国有企业,在所有者缺位的情况下,如何让企业家主动履行受托责任将有助于解决我国国有企业受托责任的问题。对此,可以通过调整利润分配来实现企业家与所有者利益的一致化,从而激励企业家主动履行受托责任。 相似文献

The last few years have witnessed important advances in our understanding of time preference and social discounting. In particular, several rationales for the use of time-varying social discount rates have emerged. These rationales range from the ad hoc to the formal, with some founded solely in economic theory while others reflect principles of intergenerational equity. While these advances are to be applauded, the practitioner is left with a confusing array of rationales and the sense that almost any discount rate can be justified. This paper draws together these different strands and provides a critical review of past and present contributions to this literature. In addition to this we highlight some of the problems with employing DDRs in the decision-making process, the most pressing of which may be time inconsistency. We clarify their practical implications, and potential pitfalls, of the more credible rationales and argue that some approaches popular in environmental economics literature are ill-conceived. Finally, we illustrate the impact of different approaches by examining global warming and nuclear power investment. This includes an application and extension of Newell and Pizer [‘Discounting the benefits of climate change mitigation : how much do uncertain rates increase valuations?’ Journal of Environmental Economics and Management 46 (2003) 52] to UK interest rate data. 相似文献
