我国城乡居民收入差别测度指标评析及修正

目前，国内学者采用了多种指标测度我国的城乡居民收入差别状况，但是由于这些指标都存在一些缺陷,因而不能准确地反映实际情况。文章介绍和评析了这些测度指标，并提出了调整的城乡居民人均实际可支配收入比指标，用以修正对我国城乡居民收入差别的测度。     

证券交易机制影响股价吗?——对中国股票市场的再检验

本文在对分别按照开盘价和收盘价计算的两种收益率的比较中发现了极值聚集现象 ,文中将形成这一现象的原因归结于市场中涨跌幅限制的存在 ,并建立了一个简单模型对此进行了说明。其后 ,利用市场中不存在涨跌幅限制时期的数据对该模型进行了验证。在结论部分 ,本文分析了除交易机制外造成两种收益率差异的其他因素 ,并认为有关交易机制对股价行为影响的研究有待深入。     

我国建造合同准则与国际准则的比较分析

会计准则的实质是一种规范，起着保证会计信息在国际间可比的重要作用。市场经济的发展要求我国加快会计准则国际化的进，以尽快与世界经济体系接轨。本对我国的《企业会计准则－建造合同》与国际上通行的《国际会计准则第11号－建造合同》在建造合同的定义、类型、分立和合并、收入、成本、收入和费用和确认、会计估计的变更、披露等八个方面进行了对比分析，认为我国建造合同在会计准则虽然大部分已经与国际接轨，但还存在一定的差异。     

Do the Forward Sales of Real Estate Stabilize Spot Prices?

We examine the effect of forward sale (pre-sale) activities on the volatility of spot prices in the real estate market. The abundance of pre-sales data and major changes in regulatory control on the pre-sale market during the 90's in Hong Kong allow us to undertake empirical tests using Hong Kong's real estate data. Our results show that the volatility of spot prices increased significantly after forward sales were severely dampened by regulatory control measures introduced in 1994, but decreased again when the measures were partly relaxed in 1998. The results contribute to the long lasting debate on whether the introduction of a futures market reduces the volatility of spot prices. Previous studies were mainly conducted in markets with low transaction costs, notably financial markets. By utilizing the unique regulatory changes in the pre-sale market of Hong Kong, we are able to conduct an experiment on the conditional volatility of spot prices in a high information-cost environment, thereby shedding light on the important role of forward housing contracts in providing price expectation information for spot trading.     

我国金融发展与经济增长关系的区域差异分析——兼论分税制改革对金融发展与经济增长关系的影响

本文利用1979-2003年的省级面板数据，将我国分为东、中、西三大区域，考察了金融发展对经济增长的影响，结果表明：把国有商业银行贷款占GDP的比例作为金融发展的衡量指标对三大地区人均GDP均具有显著的正相关性，金融发展促进经济增长的理论在我国同样成立；但金融发展与实体经济部门之间均不存在良性互动的关系，其对经济增长的贡献仅仅停留在增加资本积累上，对资本配置效率的改善作用不大；1994年的分税制改革对金融发展促进经济增长的作用造成了显著的负面影响。因此，我国的金融体制改革需要将金融体制改革、国有企业改革、财税体制改革和政府体制改革纳入同一个分析框架中进行。     

What can we learn from past price stabilization policies and market reform in Mexico?

This paper reviews experience with policy reforms in the maize sector in Mexico, beginning in the 1980s with particular reference to impacts on price variability. It analyses Mexico’s transition from past price stabilization policies under a state-trading enterprise to market reforms implemented during the 1990s. The nature, extent, and costs to producers and consumers of maize policies is discussed for both the pre-reform and the reform periods. Although wide ranging reforms have been introduced, impacts on efficiency and fiscal outlays have been less than expected.     

2006年石油价格展望

本文对影响2006年石油价格的因素做了系统分析。认为2006年形成油价风险的主要动因已从需求的波动转向供给的波动;2006年油价将由于供求的脆弱平衡维持高位运行的格局,并且,由于供给链中潜在的危机,油价波动性将会非常大;但在全球经济增速下降、石油需求增长放缓、石油生产国家和公司仍然在努力满足市场需求、炼油瓶颈有望缓和的大背景下,油价在2006年按2005年可比价格计不会大幅上升,不会对全球经济产生重大负面影响。     

Informed and uninformed trading on the Australian dollar

Using a high-frequency data set of the spot Australian/US dollar, this study examines the distribution of quotes, spreads, and returns across the trading day. By identifying the direction of trade and the subsequent quote returns from contributing banks, the segmented nature of the market into market-makers and informed and uninformed traders is investigated. The results suggest that the economic gain possible from private information is maximised over 2 to 5 quotes and is rapidly eroded by 20 quotes (about 2 min later during busy trading times) as other new information enters the market. Also, the analysis is revealing of discontinuities in trading and the volatility of pricing across the trading day.     

金融投机、实需与国际大宗商品价格——信息摩擦视角下的大宗商品价格影响机制研究

本文实证考察了2005-2015年金融投机和实需对国际大宗商品现货价格的影响及其作用机理。首先对具有信息噪音属性的金融投机进行了明确识别。其次,从多个维度出发区分市场信息摩擦状态,定量分析不同信息摩擦环境中金融投机和实需的影响差异。研究发现:大宗商品价格在长期中由实需因素主导,短期中由金融投机主导;短期中,相对于低信息摩擦环境,在市场波动性较高、金融压力上升以及投资者情绪高涨的高信息摩擦环境中,以金融投机为主的信息噪音对大宗商品价格的影响更强。进一步分析证实,相比于低信息摩擦环境,高信息摩擦环境中金融交易者的市场份额反而降低。据此,本文提出稳定大宗商品市场的关键在于提高市场透明度,减少信息摩擦,从市场质量出发降低信息噪音的影响。     

Cultural Differences in Online Community Motivations: Exploring Korean Automobile Online Brand Communities (KAOBCs) and American Automobile Online Brand Communities (AAOBCs)

To gain a better understanding of online brand communities, this study has examined why people joined in online brand communities and whether there were some differences in the motivations of Internet users based on different cultures. Open-ended questions were asked to the community members from both South Korean Automobile Online Brand Communities (KAOBC) and American Automobile Online Brand Communities (AAOBC) in the first stage and then generated and utilized an online survey for the study. The study found that KAOBC members tended to have a stronger social network, business, and communication motivations than AAOBC members. As a primary motivation, information seeking is the strongest motivation for members of both KAOBC and AAOBC. They had a similar level of information motivation.
