Providing Duty-Free Access to Australian Markets for Least-Developed Countries: A General Equilibrium Analysis

The Doha ministerial declaration commits WTO members to liberalising access to their markets for least‐developed countries (LDCs). Preferential trade policies have diverse impacts on the initiating country and its trading partners. These effects are of concern to scholars and policy makers. We use Australia as a case study to quantify the direct and indirect effects of providing preferential access to LDC imports entering Australian markets, using a general equilibrium model of the world economy. LDCs are projected to benefit and Australia is predicted to lose, reflecting adverse terms of trade effects. However, the magnitude of the adverse effect on Australia is small. If one was to view this initiative as an exercise in foreign aid, it suggests that Australia can provide a significant benefit to the poorest nations with which it trades, at almost no cost to itself.     

科技信用制度建设的回顾与展望

科技信用缺失给国家和社会带来了极大危害.我国自20世纪90年代以来,从加强国家科技计划项目和科学基金的管理入手,制定了一系列规范科技人员行为的政策法规,为科技信用制度建设奠定了基础.今后,这项工作的重点是：制定科技人员信用规范,建立信用信息评价指标体系,提高指标量化评价的科学性,完善信用数据库和信用信息共享平台系统,构建失信行为惩戒机制.

EDGAR on the internet: The welfare effects of wider information distribution in an experimental market for risky assets

Policies such as the SEC’s Fair Disclosure Rule, and technologies such as SEC EDGAR, aim to disseminate corporate disclosures to a wider audience of investors in risky assets. In this study, we adopt an experimental approach to measure whether this wider disclosure is beneficial to these investors. Price-clearing equilibrium models based on utility maximization and non-revealing and fully-revealing prices predict that in a pure exchange economy, an arbitrary trader would prefer that no investors are informed rather than all are informed; non-revealing theory further predicts that an arbitrary trader would prefer a situation in which all traders are informed rather than half the traders are informed. These predictions can be summarized as “None > All > Half”. A laboratory study was conducted to test these predictions. Where previous studies have largely focused on information dissemination and its effects on equilibrium price and insider profits, we focus instead on traders’ expected utility, as measured by their preferences for markets in which none, half, or all traders are informed. Our experimental result contradicts the prediction and indicates “Half > None > All”, i.e. subjects favor a situation where a random half is informed. The implication is that in addition to testing predictions of price equilibrium, experiments should also be used to verify analytical welfare predictions of expected utility under different policy choices.

Using data envelopment analysis approach to estimate the health production efficiencies in China

By using Data Envelopment Analysis approach, we treat the health production system in a certain province as a Decision Making Unit (DMU), identify its inputs and outputs, evaluate its technical efficiency in 1982, 1990 and 2000 respectively, and further analyze the relationship between efficiency scores and social-environmental variables. This paper has found several interesting findings. Firstly, provinces on frontier in different year are different, but provinces far from the frontier keep unchanged. The average efficiency of health production has made a significant progress from 1982 to 2000. Secondly, all provinces in China can be divided into six categories in terms of health production outcome and efficiency, and each category has specific approach of improving health production efficiency. Thirdly, significant differences in health production efficiencies have been found among the eastern, middle and western regions in China, and among the eastern and middle regions. At last, there is significant positive relationship between population density and health production efficiency but negative relationship (not very significant) between the proportions of public health expenditure in total expense and efficiency. Maybe it is the result of inappropriate tendency of public expenditure. The relationship between abilities to pay for health care services and efficiency in urban areas is opposite to that in rural areas. One possible reason is the totally different income and public services treatments between rural and urban residents. Therefore, it is necessary to adjust health policies and service provisions which are specifically designed to different population groups. __________ Translated from Jingji Yanjiu 经济研究 (Economic Research Journal), 2006, (7): 92–105
