金融监管效率的基石:激励相容的监管机制

本文通过金融监管过程中的博弈分析,揭示了当前的金融监管制度安排在信息不对称条件下导致的监管当局提供有效监管激励的缺失及金融机构普遍的道德风险是造成金融监管失灵的主要原因.因而解决金融监管低效率或失灵问题的关键,在于通过金融市场透明度建设、监管制度安排的合理设计及金融机构治理结构的完善,实现社会公众、监管当局、金融机构之间的激励相容.     

Signalling,Disclosure And The Implications Of Financial Structure For Uk Corporate R&D ∗

This paper investigates the impact of R&D disclosure and finance variables on the level of R&D expenditures. The question addressed is: what is the impact of changes in disclosure requirements on the relationship between R&D expenditure and the financing of firms? The question is motivated by the possible signalling role that elective disclosure may have had prior to changes in accounting practices to ensure R&D disclosure.     

Licensing policies for a new product

This paper studies licensing policies for the owner of a new product and addresses their welfare impact in the assessment of market failures. We show that the best licensing policy for the patent holder is fixed fee licensing with an exclusive territory clause. Consumers are also better off with fixed fees but do not prefer the exclusive territory clause. Social welfare is higher under exclusive territories when fixed costs are not too large. As for efficiency, the number of licences in the private market equilibrium falls short of the socially optimal solution. Our analysis discloses that (i) any policy measures aimed at enhancing the diffusion of technology, in terms of the number of licences, would be welcomed and, (ii) the permissive treatment received by licensing agreements with exclusive territories is justified.     

Pharmacoeconomic analysis of paricalcitol and calcitriol in the treatment of secondary hyperparathyroidism in haemodialysis: impact of hospitalisations and survival

Summary

The objective of this study was to evaluate the cost effectiveness of paricalcitol injection compared with calcitriol injection when used to reduce parathyroid hormone levels in patients undergoing haemodialysis. A decision tree was developed to model the 1-year costs and outcomes of therapy for secondary hyperparathyroidism from a US government payer's perspective (2005 US$). Probabilities of hospitalisations and survival with paricalcitol and calcitriol were obtained from published observational studies.

When only drug costs and survival were considered, the incremental cost effectiveness of paricalcitol over calcitriol was $9,900 per life saved. When utilities were included, the incremental cost-effectiveness ratio for paricalcitol compared with calcitriol was $13,200 per quality-adjusted life year. When both drug and hospitalisation costs were included in a cost analysis, paricalcitol treatment was cost saving compared with calcitriol, and when hospitalisation costs were included in both the cost-effectiveness analysis and cost-utility analysis paricalcitol demonstrated first-order dominance, cost savings and cost effectiveness.

This decision analysis demonstrated that paricalcitol injection is both cost effective and cost saving compared with calcitriol injection.
