Michael Porter, the influential Harvard management guru, has promoted the idea that compliance with stricter environmental regulations can afford secondary benefits to firms through improved product design, innovation, corporate morale and in other ways. Once these secondary benefits are factored, the net cost of compliance is argued to be lower than conventionally thought and may even be negative. Whilst environmental economists have rejected the Porter Hypothesis as being based on excessively optimistic expectations of the likely size of such secondary benefits the underlying ideas do enjoy significant credence in the business community. In the context of a lobbying model of regulatory policy-making we argue that the EPA should change the way it conducts regulatory policy to take account of Porter's views – even if it knows those views to be misguided. The model serves to illustrate the more general point that fashions in management thinking can be expected to impact the optimal conduct of regulatory policy. 相似文献

This study presents theoretical arguments and evidence that attempt to show the contribution of economic mechanisms typical
of a business for resolving problems of environmental protection. Firstly, a brief synopsis is given of the classic solutions
that environmental economics proposes for correcting environmental externalities. Next, the benefit of expanding these two
mechanisms is discussed so that they include those intermediate mechanisms for which it is not possible to clearly establish
if they are developed within the domain of the market or the business. The study's focus resides in the fact that the explicit
expansion of the range of solutions proposed from a macroeconomic point of view establishes a connecting point between environmental
economics and business economics, an area in which academic attention to environmental matters has been significantly less.

An economic system which exhibits chaotic behaviour has been stabilized on various periodic orbits by use of the Ott-Grebogi-Yorke method. This procedure has been recently applied to controlling chaotic phenomena in physical, chemical and biological systems. We adopt this method successfully for Feichtinger's generic model of two competing firms with asymmetrical investment strategies. We show that the application of this control method to the particular economic process considered brings a substantial advantage: one can easily switch from a chaotic trajectory to a regular periodic orbit and simultaneously improve the system's economic properties. Numerical simulations are presented in order to illustrate the effectiveness of the whole procedure.The work was supported by the Alexander von Humboldt-Stiftung and by the Polish National Council (KBN) Grant No 2 P302 038 04. 相似文献

This paper focuses on problems associated with nonresponse in Contingent Valuation surveys. The results from a telephone follow-up survey show that value inference can be considerably improved by information on nonrespondents' attitudes. 相似文献

This paper tests the permanent income hypothesis (PIH) for public consumption. Unlike private agents, a government is a representative national, infinitely-lived agent that usually faces no liquidity constraints. Thus, the expectation is that the PIH restrictions should not be rejected for public consumption. However, using U.S. data, the paper is unable to find evidence supporting the permanent income model of public consumption. Public consumption is found to be sensitive to lagged public income and too smooth relative to permanent public income. The results therefore cast doubt on the characterization of the public sector as a social welfare optimizing agent. 相似文献

Cost Heterogeneity and the Potential Savings from Market-Based Policies 总被引:10,自引:0,他引:10
Policy makers and analysts are often faced with situations where it is unclear whether market-based instruments hold real promise of reducing costs, relative to conventional uniform standards. We develop analytic expressions that can be employed with modest amounts of information to estimate the potential cost savings associated with market-based policies, with an application to the environmental policy realm. These simple formulae can identify instruments that merit more detailed investigation. We illustrate the use of these results with an application to nitrogen oxides control by electric utilities in the United States. 相似文献
