新会计准则对上市公司信息披露的影响分析

本文在回顾我国会计准则变迁以及概括新准则主要变化的基础上,从内容和形式两个方面研究了新准则对上市公司信息披露的影响。认为新准则对信息披露的影响主要表现在财务报告的构成方面,财务报告的组成及其格式都发生了较大的变化。这些形式和内容上的变化使得新会计准则对上市公司的信息披露提出了更高的要求,上市公司信息披露的逐步完善将有助于投资者做出更准确的投资决策,降低投资风险,必将提高上市公司财务报告的使用价值,增强上市公司业绩的可预测性。     

FASB公允价值计量准则的制定及其框架

金融工具和衍生金融工具的产生和发展,使公允价值日益受到会计学术界和实务界的广泛关注。公允价值的实施必须解决其计量问题,FASB在2004年推出的公允价值计量准则征求意见稿引起了美国社会各界的强烈反响。经过反复讨论,FASB在2005年发布了准则草案,并计划在2006年正式发布公允价值计量准则。本文主要介绍FASB公允价值计量准则草案的基本框架。     

Matching and anonymity

This work introduces a set-theoretic foundation of deterministic bilateral matching processes and studies their properties. In particular, it formalizes a link between matching and informational constraints by developing a notion of anonymity that is based on the agents’ matching histories. It also explains why and how various matching processes generate different degrees of “informational isolation” in the economy. We illustrate the usefulness of our approach to modeling matching frameworks by discussing the classical turnpike model of Townsend.This research is supported in part by the NSF grants EIA-0075506, SES-0128039, DMS-0437210, and ACI-0325846. We thank two anonymous referees for constructive comments that improved the exposition of the paper. We also thank the participants in seminars at the University of Aarhus, Purdue University, University of Texas at Austin, and at the XI Meeting on Real Analysis and Measure Theory in 2004, the spring 2004 Midwest Economic Theory Meeting, the summer 2004 North American and European Econometric Society meetings.     

市场经济运行中的效率与公平及分配正义辨正

要建立一个真正意义上的和谐社会,必须以实现分配正义为前提.而仅靠市场经济的分配模式尚不能实现合理、公正的分配,解决社会不公问题.政府介入是经济运行的必要调控手段,政府介入到市场经济的运行中来,必然会面临如何处理公平与效率的关系问题.只有理顺这一关系才能使社会财富的分配走向更加合理化,才能创造一个和谐的制度环境,从而实现和谐社会构建.     

Climate Change Taxes and Energy Efficiency in Japan

In 2003 Japan proposed a Climate Change Tax to reduce its CO₂ emissions to the level required by the Kyoto Protocol. If implemented, the tax would be levied on fossil fuel use and the revenue distributed to encourage the purchase of energy efficient equipment. Analysis using the MIT Emissions Prediction and Policy Analysis (EPPA) model shows that this policy is unlikely to bring Japan into compliance with its Kyoto target unless the subsidy encourages improvement in energy intensity well beyond Japan’s recent historical experience. Similar demand-management programs in the US, where there has been extensive experience, have not been nearly as effective as they would need to be to achieve energy efficiency goals of the proposal. The Tax proposal also calls for limits on international emission trading. We find that this limit substantially affects costs of compliance. The welfare loss with full emissions trading is 1/6 that when Japan meets its target though domestic actions only, the carbon price is lower, and there is a smaller loss of energy-intensive exports. Japan can achieve substantial savings from emissions trading even under cases where, for example, the full amount of the Russian allowance is not available in international markets.     

控制火电厂二氧化硫排放的有效途径——排污权交易

目前,我国工业二氧化硫排放量中有42%是火电厂排放的,因此高效控制火电厂的二氧化硫排放是提高空气质量的主要途径。美国利用排污权交易治理火电厂的二氧化硫排放取得了巨大的成功,不仅二氧化硫排放量大幅下降,而且排污权交易也被证明是成本最低的方法。借鉴美国的经验,可以为我国治理火电厂二氧化硫排放提供高效途径。     

论排污权交易

排污权交易是一种采用经济手段进行环境保护的手段,越来越多地受到了国际及国内社会的重视。本文对排污权交易进行了系统地介绍,论述了排污权交易的含义、性质、目的、特征,并在此基础上论述了排污权交易法律关系的构成。最后,对我国的排污权交易制度建立的障碍进行了分析,提出了构建我国排污权交易制度的若干设想。     

实现教育公平构建和谐社会

要实现包括高等教育在内的教育公平,必须按照胡锦涛总书记的要求,"坚持教育的公益性质,加大财政对教育投入,规范教育收费,扶持贫困地区、民族地区教育,健全学生资助制度",统筹兼顾,实现高等教育发展的均衡化。     

竞争力、市场微观结构与证券交易所变革

纽约证券交易所和纳斯达克实施的重大并购行动标志着全球证券交易所新一轮并购浪潮的兴起,证券交易所之间的竞争再度趋于白热化.交易所之间的竞争已演变为市场微观结构的竞争.本文对纽约证券交易所和纳斯达克的交易成本进行了比较,无论是上市成本还是交易成本,新兴的纳斯达克都比传统的纽约证交所更胜一筹.因而本文认为有效降低交易成本应是提高交易所核心竞争力的关键所在,而改进交易机制、拓展产品服务以及调整组织架构,可以作为降低交易成本、提高交易所竞争力的具体竞争策略.     

The Underpricing and Excess Returns of Initial Public Offerings in Taiwan Based on Noisy Trading: A Stochastic Frontier Model

Initial public offerings (IPOs) are typically offered at prices lower than the transaction price in the early aftermarket. With a stochastic frontier model, we measured the fair offer price of an IPO and then the deliberate IPO underpricing and the market misvaluation based on the estimated fair offer price. Our results show that IPOs are deliberately underpriced. The extent of noisy trading leading to significantly higher market transaction prices explains the excess IPO returns. We conclude that initial IPO returns result primarily from the noisy trading activities instead of the deliberate IPO underpricing.
