Despite the entry into force of the Kyoto Protocol, the US decision not to comply with its Kyoto commitments seems to drastically undermine the effectiveness of the Protocol in controlling GHG emissions. Therefore, it is important to explore whether there are economic incentives that might help the US to modify its current decision and move to a more environmentally effective climate policy. For example, can an increased participation of developing countries induce the US to effectively participate in the effort to reduce GHG emissions? Is a single emission trading market the appropriate policy framework to increase the signatories of the Kyoto Protocol? This paper addresses the above questions by analysing whether the participation of China in the cooperative effort to control GHG emissions can provide adequate incentives for the US to re-join the Kyoto process and eventually ratify the Kyoto Protocol. This paper analyses three different climate regimes in which China could be involved and assesses the economic incentives for the major world countries and regions to participate in these three regimes. The main conclusion is that the participation of the US in a climate regime is not likely, at least in the short run. The US is more likely to adopt unilateral policies than to join the present Kyoto coalition (even when it includes China). However, a two bloc regime would become the most preferred option if both China and the US, for some political or environmental reasons, decide to cooperate on GHG emission control. If the US decides to cooperate, the climate regime that provides the highest economic incentives to the cooperating countries is the one in which China and the US cooperate bilaterally, with the Annex B?US countries remaining within the Kyoto framework.  相似文献

Here we consider two ways that nanomedicine might be disruptive. First, low-end disruptions that are intrinsically unpredictable but limited in scope, and second, high end disruptions that involve broader societal issues but can be anticipated, allowing opportunity for ethical reflection.  相似文献

This paper develops an analytical framework tointegrate static and dynamic effects of theoreticallyrelevant and practically applied investment-decisioncriteria on the marginal rate of substitution betweeninvestment and labour. The new propositions are relatedto the ranking of relative present value, Kalecki'sindex of efficiency and the static version ofrecoupment period criteria. Investors in post-communisteconomies have switched from the recoupment period tothe criteria based on discounting. This is aninstitutional change typical for these economies. Itimplies a choice of techniques with lower investmentintensity, which is best supported by government'spolicy to promote labour mobility.  相似文献
