保定市大学生医疗保险制度运行探析

为帮助大学生顺利完成学业,保障大学生享有基本医疗卫生服务权益,国务院于2008年年底决定将大学生纳入城镇居民基本医疗保险试点范围。制度运行两年多来取得了可喜的成绩,也暴露出许多问题。通过对保定市六所高校在校生进行问卷调查,发现问题集中表现为:大学生对制度了解较少,参保率低,学校医疗机构服务质量差、效率低,制度保障范围狭窄,转移接续难等。本文将根据分析结果,阐述问题根结所在,并试提出解决方案。目的是使大学生医疗保险制度真正能提高大学生的医疗福利水平,减轻大学生的医疗费用的负担。

Stochastic equilibria of an asset pricing model with heterogeneous beliefs and random dividends

We investigate dynamical properties of a heterogeneous agent model with random dividends and further study the relationship between dynamical properties of the random model and those of the corresponding deterministic skeleton, which is obtained by setting the random dividends as their constant mean value. Based on our recent mathematical results, we prove the existence and stability of random fixed points as the perturbation intensity of random dividends is sufficiently small. Furthermore, we prove that the random fixed points converge almost surely to the corresponding fixed points of the deterministic skeleton as the perturbation intensity tends to zero. Moreover, simulations suggest similar behaviors in the case of more complicated attractors. Therefore, the corresponding deterministic skeleton is a good approximation of the random model with sufficiently small random perturbations of dividends. Given that dividends in real markets are generally very low, it is reasonable and significant to some extent to study the effects of heterogeneous agents’ behaviors on price fluctuations by the corresponding deterministic skeleton of the random model.     

Does trade integration alter monetary policy transmission?

This paper explores the role of trade integration—or openness—for monetary policy transmission in a medium-scale new Keynesian model. Allowing for strategic complementarities in price setting, we highlight a new dimension of the exchange rate channel by which monetary policy directly impacts domestic inflation: a monetary contraction which appreciates the exchange rate lowers the local currency price of imported goods; this, in turn, induces domestic producers to lower their prices too. We pin down key parameters of the model by matching impulse responses obtained from a vector autoregression on time series for the US relative to the euro area. Our estimation procedure yields plausible parameter values and suggests a strong role for strategic complementarities. Counterfactual simulations show that openness alters monetary transmission significantly. While the contractionary effect of a monetary policy shock on inflation and output tends to increase in openness, we find that monetary policy's control over inflation increases, as the output decline which is necessary to bring about a given reduction of inflation is smaller in more open economies.

构建油田企业单项资产全寿命周期效益评价体系的思考

目前油田企业的资产管理方面存在诸多问题,如油气资产折旧、折耗及报废不合理,资产闲置严重,资产管理制度不完善及管理责任不够明确等问题。随着勘探开发的不断深入和企业自身的滚动发展,为了节减成本提高资产经营效率,油田企业需加强自身资产的管理。对于如何才能全面反映资产整个寿命周期各个阶段的管理状况,应该采用何种分析方法,评价指标、评价方法和评价标准进行构建评价体系等本文做了进一步的思考与探讨。     

变频器固定频率控制在超长链条输送线中的应用

XX公司为了降低从车间1到车间2输送物料的运输成本,在车间1和车间2之间建设了一条总长650米的链条输送线,用于物料的连续输送。由于原控制系统存在诸多缺陷,并缺乏及时的售后服务,特组织公司内外技术力量对该输送系统进行了技术研究,制定了"变频器多段固定频率控制"方案。本文主要介绍了该输送系统的功能、系统改造方案的具体设计及改造后系统的运行调试,实践证明该方案大大降低了故障率,提高了系统的稳定性。
