This paper considers the effect of rent-seeking on the welfare implications of price discrimination by a monopolist. It is shown that even when rent-seeking fully dissipates monopoly profits, it is possible for price discrimination to raise social welfare. Thus, the recognition that monopoly profits attract resource using, socially wasteful activities, does not necessarily negate price discrimination as a defence of monopoly. 相似文献

The People's Republic of China is experiencing severe air pollution with very serious public health and economic consequences. Over the past decade, the Chinese government has sought to utilize bureaucratic, political, legal and educational vehicles to address these problems. This paper examines the ways in which those policy measures have been communicated to, understood by, and acted upon by the citizenry, drawing in important part on household and epidemiological surveys conducted in Anhui. Our study suggests that the central government's message has yet to be absorbed to the degree intended and then considers both why this has been the case and how the effectiveness of policy mechanisms might be enhanced. 相似文献

Standards of reasonability play an important role in some of the most difficult cases of rape. In recent years, the notion of the reasonable person has supplanted the historical concept of the reasonable man as the test of reasonability. Contemporary feminist critics like Catharine MacKinnon and Kim Lane Scheppele have challenged the notion of the reasonable person on the grounds that reasonability standards are gendered to the ground and so, in practice, the reasonable person is just the reasonable man in a gender neutral guise. These critics call for the explicit employment of a reasonable woman standard for application to the actions of female victims of rape. But the arguments for abandoning a gender-neutral standard are double-edged and the employment of gendered standards of reasonability is likely to have implications that are neither foreseen by, nor acceptable to, advocates of such standards. Reasonable agent standards can be dropped, in favor of appeals to the notion of a reasonable demand (or expectation) by the law. However, if reasonable agent standards are to be retained, gendered versions of such standards are not preferable to gender-neutral ones. 相似文献

The Kyoto Protocol on climate change includes four flexibility mechanisms, which pursue lower-cost global reduction of greenhouse gas emissions through voluntary international re-distribution of abatement effort. We consider the operation of one of these, the Clean Development Mechanism (CDM), which grants transferable credit for abatement achieved by individual projects in countries without national emission targets. An uncredited pilot phase in effect since 1995 provides only limited guidance for projecting the operation of the credited CDM. Under the CDM, intractable difficulties of accounting for project-level effects are likely to bias project activity toward particular project types for which exaggeration-resistant accounting rules are most readily available. This bias will favor retrofits over new investments, and will consequently limit the CDM to a modest contribution to required abatement in developing countries. Use of CDM credits as instruments of domestic policy in investor countries, as well as instruments of international policy, may mitigate this bias and the associated limitation. So may the use of projects based on novel technologies of carbon management. 相似文献
