Individual and Institutional Investors’ Response to Earnings Reported by Conservative and Non‐Conservative Firms: Evidence from Chinese Financial Markets

In this study, we document that there are significant differences in individual and institutional investors’ perception and interpretation of information based on accounting conservatism, as reflected by their trading behavior in the Chinese financial market. Our findings show that institutional investors, who are more sophisticated and have better skills, engage in higher purchases of equities of firms that use high accounting conservatism compared to the firms that use low/no accounting conservatism. Institutional investors’ equity purchases are even higher if these firms are associated with higher growth opportunities. On the other hand, individual investors are attracted more by the attention‐grabbing events and are motivated to purchase equities of firms that either do not use accounting conservatism or use low accounting conservatism, and their purchases are even higher when the firms report positive earnings surprises. Additionally, we find that abnormal returns are higher for the firms using high accounting conservatism and have experienced higher purchases by institutional investors.     

Slicing,Dicing, Spicing,and Pricing: Factors Influencing Purchase and Consumption of Fresh Potatoes

To better understand potential reasons for a North American decline in fresh potato consumption, a region-wide survey (n = 1009) was undertaken in eastern Canada. Results were examined comparing high- and low-frequency potato users on a variety of factors, including beliefs, attitudes, barriers, needs, and satisfaction with potatoes. Respondents indicated positive perceptions pertaining to potato nutrition, taste, preparation, and overall enjoyment. Multiple logistic regression analysis suggested two variables—age and the perceived importance of potatoes for the everyday meal—were strong predictors of high versus low frequency of potato consumption. Respondents judged the ability to see the potato in the package, potato firmness, and locally produced as point-of-purchase characteristics particularly important when buying fresh potatoes. However, respondents also indicated that their needs were not fully met and expressed relatively low levels of satisfaction when purchasing potatoes. Based on the results, suggestions are provided for improving the marketing of fresh potatoes.     

Participation and retention in a green tourism certification scheme

Tourism certification schemes offer a transitional procedure to a more transparent and sustainable tourism product. Engaging current and previous Green Tourism Business Scheme (GTBS) members in Scotland, this research addresses issues of retention affecting progression of sustainable tourism supply. Quantitative analysis tracking GTBS members over three time points reveals 2% growth but conceals significant flux in membership. Retention was calculated at 66%, where business type analysis discloses distinct issues among accommodation providers with 42% departing the scheme. Decline is greatest among B&;Bs and guesthouses (?61%), where poor and falling recruitment coincides with very poor retention (33%). Our analysis demonstrates that slow growth in membership is primarily a result of enterprises choosing to leave the scheme, rather than poor recruitment. Questionnaires from past and present GTBS members (n = 109) confirm the importance of personal pro-environmental philosophies and perceived business benefits in attracting members, yet anticipated benefits do not always materialise. The main reasons for leaving the GTBS relate to membership cost and unrealised benefits. Lack of scheme awareness, management, criteria, bureaucracy and time commitment were further departure factors. The paper offers some suggestions to address issues and enhance retention leading to sustainable growth among tourism certification schemes.     

Enhancing Governmentally Sponsored Export Promotions Through Better Segmentation of the Market of a State's Manufacturing Concerns

This article presents methodology for identifying product categories that, if they were made the subjects of a specified state's export promotions, would hold promise for satisfying relevant needs of members of three key “stakeholder” groups regarding the outcomes of the governmentally sponsored export promotions: the World Trade Organization (WTO), managements of non-exporting, small- and- medium-sized (SME) manufacturing concerns, and governmental entities who are responsible for raising funds to support such promotions. Methodology is applied in the context of a state in the United States (North Carolina).

The methodology is then applied in the context of a state in the United States (North Carolina). The presentations of the results of the application of the methodology at each of the 2-, 4- and 6-digit HS-coded product category levels are in each case followed by discussions of implications of the results.     

Portfolio Optimization under Solvency Constraints: A Dynamical Approach

We develop portfolio optimization problems for a nonlife insurance company seeking to find the minimum capital required that simultaneously satisfies solvency and portfolio performance constraints. Motivated by standard insurance regulations, we consider solvency capital requirements based on three criteria: ruin probability, conditional Value-at-Risk, and expected policyholder deficit ratio. We propose a novel semiparametric formulation for each problem and explore the advantages of implementing this methodology over other potential approaches. When liabilities follow a Lognormal distribution, we provide sufficient conditions for convexity for each problem. Using different expected return on capital target levels, we construct efficient frontiers when portfolio assets are modeled with a special class of multivariate GARCH models. We find that the correlation between asset returns plays an important role in the behavior of the optimal capital required and the portfolio structure. The stability and out-of-sample performance of our optimal solutions are empirically tested with respect to both the solvency requirement and portfolio performance, through a double rolling window estimation exercise.     

采购人员的激励问题研究

由于采购企业与其内部的采购人员之问存在着信息的不对称及两者目标的不一致,故二者之间存在着委托代理关系.运用委托代理模型,在考虑采购产品性质、外部随机因素、采购人员成本、采购人员的效用函数等因素的情况下,通过对模型解的分析,给出了影响激励采购员激励强度的各种因素,提出了采购产品的性质等几种不同情况下的激励强度,并针对此提出了一系列具体的激励措施.
