论会计目标的层次性

在“决策有用观”会计目标的指导下,美国财务会计准则委员会制定的财务会计准则离财务会计工作的固有规律越来越远,导致财务造假事件越来越严重,会计的真实性原则(客观性)受到严重挑战,第七号概念框架的颁布使这一现象走到了极端。之所以会出现如此结果,是因为美国财务会计准则委员会以偏概全,依个别代表整体做法的必然结果。文章从会计的本质出发,指出:会计目标应该是分层次性的,“决策有用观”只是在特定经济环境下使用会计信息子系统的目标,它不能代表整个会计信息系统的目标,整个会计信息系统的总目标应该是“四观合一”的目标体系。     

经济转型中制度变迁的动态分析

本文运用随机动态博弈理论，通过对制度的结构动态分析，阐明了转型过程中的不确定性，经由有限理性个体的行为机制，作用于制度变迁过程的机理，并由此论证转型过程中秩序对于成功实现制度创新的根本意义。尤其是，当经济转型所引起的不确定性，导致制度变迁的多向性（或多重均衡性），从而难以自发达到“有效”的渐近稳定均衡时，我们有必要重新思考转型经济国家在促进秩序重建过程中所扮演的角色。     

Order Effect and Vendor Inspection in Online Comparison Shopping

In the context of online comparison shopping, the phenomenon of order effect and its impact has profound theoretical and practical significance, as many search engines and shopping portals offer paid placement and paid inclusion in search results. In this study, we investigate how order effects and other market competitive factors work together to attract consumers’ attention to online vendors, which is manifested by the time spent on collecting more vendor information, and the probability of a vendor being included in a consumer’s consideration set. We found that the effect of serial position of a vendor in a list is mediated by consumers’ attention which in turn affects the probability of the vendor being accepted.

Multi-objective supplier selection and order allocation under disruption risk

We formulate a multi-objective MILP model to find the optimal choice of suppliers and their order quantity allocation under disruption risk. Suppliers are evaluated and ranked, based on the preference values obtained using a hybrid fuzzy AHP-fuzzy PROMETHEE. Multi-objective Particle Swarm Optimization is then applied to yield a set of Pareto-optimal solutions for the choice of suppliers and their order allocation. Numerical experimentation suggests that the supplier failure probability affects the expected total cost more than supplier flexibility and loss cost. Sensitivity analysis is performed on the failure probability, the output flexibility, and loss cost of the suppliers.     

Firm size,ownership structure,and systematic liquidity risk: The case of an emerging market

Previous studies support the hypothesis that institutional ownership leads to an enhanced systematic liquidity risk by increasing the commonality in liquidity. By using a proprietary database of all incoming orders and ownership structure in an emerging stock market, we show that institutional ownership leads to an increase in commonality in liquidity for mid- to-large cap firms; however, only individual ownership can lead to such an increase for small cap firms, revealing a new source of systematic liquidity risk for a specific group of firms. We also reveal that commonality decreases with the increasing number of investors (for both individual and institutional) at any firm size level; suggesting that as the investor base gets larger, views of market participants become more heterogeneous, which provides an alternative way to decrease the systematic liquidity risk.     

Liquidity,liquidity risk,and information flow: Lessons from an emerging market

This paper examines the role of public and private information flows in intraday liquidity and intraday liquidity risk in the Tunisian stock market. Our empirical results are based on ARMA and GARCH-type models and show that, for major Tunisian stocks, gradually elapsed public information together with gradually elapsed private information in the market is the dominant factor in liquidity improvements in the Tunisian stock market. Liquidity improvements are generated by a decrease in the bid-ask spread accompanied by an increase in the depth at best limit. Our results clearly indicate that the arrival of public information in a sequential manner is the dominant factor generating increases in liquidity risk related to the bid-ask spread, while the advent of private information in a contemporaneous manner is the dominant factor generating increases in liquidity risk related to the depth at best limit. Additionally, our results show that liquidity risk persistence disappears when trading volume and order imbalance are included as explanatory variables in the conditional variance equation.     

Market reaction to quantitative and qualitative order backlog disclosures

Analysts and practitioners have long sought information on order backlog (OB) as indicators of future sales, and in turn, of future earnings and stock returns. OB disclosures, though mandatory for annual reports, are voluntarily included in some quarterly reports and are sometimes presented only in textual narration. Given that the required annual OB data may be partially preempted by voluntary quarterly disclosures, we test whether quarterly OB disclosures are used by market participants, especially the qualitative OB disclosures, which were not tested before. We show that OB growth is helpful in forecasting future sales and thus assign a positive tone to qualitative OB disclosures that indicate OB growth. Both quarterly quantitative OB increases and positive qualitative tone are associated with immediate and drift returns, after controlling for other disclosures during the quarterly earnings announcements and variables that affect voluntary disclosure. Our results indicate that regulators may need to consider requiring OB disclosures in quarterly intervals when OB is sufficiently material.     

Evaluating Wisconsin dairy producer compliance and potential eligibility for international markets under existing European Union and United States Grade “A” bulk tank somatic cell count compliance criteria

A proposal to lower the bulk tank Somatic Cell Count (SCC) maximum for United States of America (US) Grade “A” milk producers was not adopted by the National Conference on Interstate Milk Shipments in 2011 or 2013. The proposal would have made the US Grade “A” limit consistent with many other international standards, including that of the European Union (EU). Some US states, however, have proactively adopted their own SCC limit to mirror the EU limit. The purpose of this study was to analyze the impacts on Wisconsin dairy producers if Wisconsin should adopt the current EU limit and compliance criterion. Analyses were done on SCC results for Wisconsin Grade “A” and Grade “B” dairy producers reported each month to the Wisconsin Department of Agriculture, Trade and Consumer Protection (WDATCP) during January 1, 2009–December 31, 2012. Results were evaluated against the current US Grade “A” and EU compliance criteria for SCC and the percentage of (producer × month) combinations in compliance was determined. If the current EU SCC compliance criterion was in place, 86.7–94.3 and 64.3–77.3% of Wisconsin Grade “A” and “Grade “B” (producer × month) combinations, respectively, would have been in compliance for the years 2009–2012. Compliance of Wisconsin Grade “A” and Grade “B” producers with the existing US SCC compliance criterion during the same period was 99.3–99.7% and 87.9–93.9% (producer × month combinations) respectively. An analysis of a subset of Wisconsin Grade “A” producers indicated that smaller-volume producers were less likely than larger-volume producers to meet the EU criterion.     

中国基础设施投资的最优规模与最优次序——基于1996-2008年各省市地区面板数据分析

本文克服各项基础设施同时回归导致的多重共线性问题,基于基础设施的边际产出与最优规模分析框架,采用中国1996-2008年各省市地区面板数据实证研究发现:中国电力、燃气和水的生产与供应业、交通运输、仓储和邮电通信业、水利、环境和公共设施管理业等各项基础设施和政府总投资的边际产出分别为5.765、2.520、1.420和1.276;最优规模分别为4.66%、3.29%、5.02%和20.95%;各项基础设施的实际投资均低于最优规模。因此,为使政府投资收益最大化可按边际产出大小顺序优先次序投资;而根据各项基础设施投资的缺口和紧迫程度,则应按实际投资与最优规模差距由大到小顺序进行投资。
