相互制农业保险在我国的困境及适用性

相互制保险在农业保险领域有着明显的优势。然而,相互制保险管理制度上的缺陷及其与农业保险的矛盾制约着相互制农业保险的发展。目前,在我国合作意识不强、农村合作经济组织发育不健全的情况下,开展相互制农业保险还有一定困难。因此,要开展相互制农业保险,必须选择合适的范围和地区,并对相互制保险进行制度创新,为相互制农业保险提供财政补贴,建立再保险机制,加强引导,减少行政干预。     

以扩大内需促进就业问题研究

随着我国经济进入新的发展阶段后,投资对劳动力逐渐显现出排挤作用,出口也由其发展前景受限而对劳动力的吸纳作用减弱。而内需由于其对劳动密集型产业产品的需求,对就业有很强的带动作用。本文将论述以内需扩大就业的必要性,找出其中存在的问题,并提出相应建议。

Towards a complete real-time electricity market design

The general design for the real-time electricity market presented in this paper optimizes and prices both real and reactive power simultaneously in an AC setting, where all assets—generation, load and transmission—are allowed to bid and are financially settled at the locational price times energy consumed or produced. The result is that transmission lines are compensated for both capacity and admittance, providing incentives for efficient operation of transmission-related assets such as FACTS devices, if price-taking behavior is assumed. Losses are incorporated into the design and become an operating cost for transmission. The market design is shown to be revenue neutral and, under some assumptions, nonconfiscatory.      

Bayesian MCMC Mapping of Quantitative Trait Loci in a Half-sib Design: a Graphical Model Perspective

Graphical models provide a powerful and flexible approach to the analysis of complex problems in genetics. While task-specific software may be extremely efficient for any particular analysis, it is often difficult to adapt to new computational challenges. By viewing these genetic applications in a more general framework, many problems can be handled by essentially the same software. This is advantageous in an area where fast methodological development is essential. Once a method has been fully developed and tested, problem-specific software may then be required. The aim of this paper is to illustrate the potential use of a graphical model approach to genetic analyses by taking a very simple and well-understood problem by way of example.     

IntraLATA long-distance demand: carrier choice, usage demand and price elasticities

Competition in the long-distance market in the US continues to intensify; the 1996 Telecommunications Act has led to increased competition in long-distance telephony especially as the Regional Bell Operating Companies have begun to gain entry to long-haul, long-distance markets. In order to better understand the implications of having increased service offerings, models of how customers choose between carriers (and the impact of this choice on subsequent usage) will be useful. We develop the first publicly available models that simultaneously estimate choice and usage for intraLATA long-distance in the US. Utilizing a generalized Tobit model, the price responsiveness of usage and carrier choice are estimated. The results are generally consistent with expectations both in terms of theory and of practical experience in the industry.

财政补贴改革刍论

财政补贴是国家宏观调控的杠杆之一,但是,目前补贴不规范,财政补贴数额大、项目繁杂,补贴效果‘异化’,加大了社会不公。为了强化财政补贴杠杆功能,提高财政补贴效益,必须按照建立公共财政的要求,本着满足公共需要原则、弹性补贴制度原则和补贴方式间接化原则,改变“一刀切”和补贴刚性的局面,确保采暖费收支合理化,取消肉食、副食品、粮食等价格补贴,改革国有企业的亏损补贴制度。
