国际油价剧烈变动对中国经济的冲击及应对策略

中国是实行油价管制的原油进口大国,在目前国内通货膨胀走高的情况下,持续的高油价必然会给我国宏观经济运行及公共财政带来压力.本文考察了我国的原油供需及石油消费现状,深入分析了油价持续高涨对我国宏观经济的影响,并通过分析日本克服石油危机的经验,针对我国国情提出相关政策建议.     

我国药品价格管理存在的问题、成因及对策

不同国家药品管理体系有较大差异,按管理主体可划分为若干类价格管理模式,各国均同时采取针对供方和需方的干预措施。目前我国药品价格存在两套管理体系,降价重点有一定偏差,差率管制政策效果不明,仍未能解决药品优质优价问题。未来应建立高效、统一的监管制度体系,依据产权关系理顺集中招标采购制度,提高价格管理的科学性与透明度。

Worst-case optimal redistribution of VCG payments in multi-unit auctions

For allocation problems with one or more items, the well-known Vickrey–Clarke–Groves (VCG) mechanism (aka Clarke mechanism, Generalized Vickrey Auction) is efficient, strategy-proof, individually rational, and does not incur a deficit. However, it is not (strongly) budget balanced: generally, the agents' payments will sum to more than 0. We study mechanisms that redistribute some of the VCG payments back to the agents, while maintaining the desirable properties of the VCG mechanism. Our objective is to come as close to budget balance as possible in the worst case. For auctions with multiple indistinguishable units in which marginal values are nonincreasing, we derive a mechanism that is optimal in this sense. We also derive an optimal mechanism for the case where we drop the non-deficit requirement. Finally, we show that if marginal values are not required to be nonincreasing, then the original VCG mechanism is worst-case optimal.
