我国城市工业污染问题的理论和现实分析

本文针对我国城市工业污染现象的原因进行分析,认为市场失灵和政府失灵是造成环境污染的原因,并认为应该从制度创新着手解决这一问题。     

Tax mix change to reduce greenhouse gas emissions*

A pollution tax or emissions trading scheme places a price on greenhouse gas emissions. This price also is an additional indirect tax and a government revenue windfall. To restore distributional equity, to avoid compounding the efficiency costs of existing distorting taxes and to maintain macroeconomic stability, it is argued that most of the revenue windfall be recycled to households as lower income tax rates and higher social security payments. As the carbon price rises over time, new and larger tax mix change packages will be required.     

The bullwhip effect on inventory: a perspective on information quality

In recent years, there has been a vast increase in the quantity of information shared across supply chain. We investigate how the timeliness and accuracy of information quality affect the value of information sharing. We use the inventory bullwhip effect (BWE) to measure the value of information sharing in a two-level supply chain consisting of one retailer and one manufacturer. The retailer faces a price-sensitive demand and the price is an AR (1) process. Our study shows if customer demand and retailer’s immediate order are delayed, using retailer’s historical order quantity to forecast can decrease manufacturer’s BWE. If information errors happen, during delivery and utilization, information sharing is not always valuable for the manufacturer. Sometimes, no information sharing can decrease much more of BWE. If information errors occur when the retailer collects demand information, value of information sharing is more significant than when there are no information errors.     

投入50亿元以奖代罚治理六省市大气污染的绩效探讨

在大气污染治理中,经济利益与环保压力、防治与排污之间的博弈,影响着大气污染治理的绩效.过去的环保政策和治理行为表明：逐利博弈下,环保治理“罚”得很困窘,防治污染的效果不大.只有设计出多重激励下的“奖”励政策,才会产生很好的大气污染治理绩效.     

室内空气污染治理技术研究现状

简述了室内空气的主要污染物及其危害,详细的论述了现阶段室内空气污染主要净化技术的原理、特点及存在的问题,并对各项技术的研究方向进行了分析。     

论信息经济发展与信息化水平测算方法

信息经济是以现代信息技术为手段,以信息资源为劳动对象而形成的以信息产业为主导产业的经济。判定一个国家或一个地区是否进入信息经济社会,主要应遵循产业结构演进的规律性、信息产业产值的大小及其年增长率高低等三条标准。由于现代信息技术的快速发展已引起了社会信息化测算对象发生了极大变化,所以必须根据这种变化研究社会信息水平测算的新方法,以便定量的测算社会信息化状态。     

The Abatement Market A Proposal for Environmental Cooperation among Asymmetric Countries

We present a model of interaction among technologically asymmetriccountries whose use of an open-access environmental resource generatesmutual externalities. We show that countries can improve bothenvironmental quality and their individual welfare levels by buying/sellingpollution abatement. This market mechanism, which reduces incentive forfree-riding, is more effective the larger the technological gap betweencountries.     

Information asymmetry,mutual funds and earnings management: Evidence from China

This paper investigates how information asymmetry and mutual fund ownership affect listed companies’ earnings management. We show that (1) reducing information asymmetry improves firms’ earnings management behavior; (2) relative to short-term mutual funds, long-term mutual funds promote earnings quality by adopting a monitoring role; and (3) by dividing firms into high/low information asymmetry groups, we find that the information environment significantly increases the effect of long-term mutual funds on firms’ earnings management. In this paper, we provide new evidence for the role that institutional investors play in a typical emerging capital market. Our results have clear policy implications: to increase earnings quality, it is essential to improve information transparency and develop long-term institutional investors.
