above the certainty level while for additive uncertainty the price should be lower than the certainty level. This note gives an intuitive explanation for the result after first presenting a parsimonious review
of the two models. We also discuss which, if either, of the two models is more realistic.

The pensions pillarisation agenda envisages a reduction in the role of social insurance while simultaneously advocating the parallel expansion of fully funded private sector, occupational and personal retirement contingencies. Widespread perception of looming state failure in the field of pensions delivery highlights the inherent limitations of current pension delivery arrangements. However, moves to de-emphasise the provision afforded by, predominantly, monopillar state-mandated pension systems by expanding private privision represent short-term palliative responses to deep rooted structural and demographic problems. Multipillar systems appear no more capable of guaranteeing system funding in the face of demographic ageing and structural unemployment than existing monopillar systems. Moreover, a diminished role for social insurance will leave the low paid and unemployed significantly more vulnerable in old age. Consequently, this paper argues for a pension reform agenda which, in terms of levels of income substitution, will secure an adequate social insurance element into the future. 相似文献

This paper contains a critique of existing legislation which deals with hazardous waste disposal and expands on the efforts
made by the Office of Technology Assessment and other economists to develop a public policy which will deal effectively with
the problems associated with hazardous waste generation and disposal. A new policy is set forth here which encourages both
waste reduction and safe disposal while providing revenue to pay for cleanups at Superfund sites. 相似文献

The House and Senate of the United States Congress recently passed legislation that directs the FCC to establish a system for using auctions to allocate the use of radio spectrum for personal communications services. There is a unique and unprecedented set of issues that arise in this context, which are of interest to economists, industry analysts, regulators, and policymakers. We discuss these issues and evaluate their likely impact on the outcome of the spectrum auctions. In addition, we argue that there may be pitfalls in the auction procedure adopted by the FCC, and we discuss possible alternative procedures. 相似文献

Previous research on unit management buyouts, UMBs, has shown that selling firms benefit from the selloff transaction. The current research demonstrates that when the selling firm has either poor liquidity or poor earnings, selling firm shareholders do not benefit as much. We hypothesize that the unit managers have knowledge about the selling firm's difficulties so they do not pay as large a premium for the assets. Since the unit managers technically are employed by the selling firm shareholders, their bargaining to achieve a better price is an agency cost. Finally, selloff frequency does not affect seller abnormal returns. 相似文献

This note provides a formal demonstration of the incentive incompatibility problem that exists in franchisor — franchisee relationships. It is shown that incentive incompatibility exists with respect to both price and quality. Several contractual mechanisms designed to mitigate the incompatibility problem are examined. 相似文献
