基于渐变思想的品牌延伸边界模型研究

首先介绍已有的基于功能一表现的品牌延伸边界模型，指出该模型的边界“突变”特性以及无法更准确地对边界内产品可延伸程度加以度量的缺点。然后提出基于品牌内产品间的关联性一致性的具有“渐变”特征的品牌延伸模型，以“海尔”品牌延伸为例进行实证分析，并探讨对该模型进一步研究和利用的方向。     

企业制度变革中的博弈与均衡——一个关于国有企业民营化的实证研究

企业制度运行以利益相关者之间的共有理念为心理依托；这种共有理念体现在人们博弈均衡之中，是人们行为选择的默认前提，其形成和发展具有不以个人意志为转移的客观规律；企业制度变革的任务，是通过企业利益相关者之间的博弈和信任，在适应和调整共有理念的基础上，塑造合理的企业控制权主体。     

Politically connected boards,value or cost: evidence from a natural experiment in China

This study investigates the net effect of a politically connected board for a firm. Using a natural experiment in China – a regulatory change to forbid bureaucrats from sitting on the board of public firms – we address the causality of the net effect of a politically connected board by testing the market reaction of the shares of firm targeted by the regulatory change to the policy announcement. The stocks of firms with politically connected directors who are targeted by the regulatory change show on average a significantly positive abnormal return, which suggests that the agency cost effect of a politically connected director dominates the value effect. The result is robust to various model settings and to a matched sample using the propensity score methodology. Additionally, the announcement effect of the resignation of a politically connected director is significantly positive, and significantly higher than that of a non‐connected director. Overall, our results suggest that the agency cost effect of a politically connected director dominates the value effect.     

Corporate Name Change and the Market Valuation of Firms: Evidence from an Emerging Market

Investors’ responses to a firm’s name change and the determinants of their response are scantly explored areas in the field of behavioral finance. Based on a sample of 415 Indian firms from 2005 to 2014, this study suggests that investors respond positively to the announcement of firm name changes. Furthermore, the study indicates that when firms do not indicate geographical specificity in the name and have a specific rather than generic name, then the firm will experience greater abnormal returns. Also, when firm names are fluent and are associated with the owner’s family name, again, abnormal returns generated are positive. Nevertheless, as a firm ages and investors gain more information about it, then abnormal returns due to name change decrease.

中国劳动力错配对TFP的影响分析

文章利用一个资源错配对TFP影响的核算框架和中国改革开放30年的宏观经济、产业相关数据,估算了当前中国农业部门就业比重过大对全要素生产率产生的影响。结果显示,改革以来,劳动力错配对TFP有着明显的负效应,以不同的指标计算,在-2%到-18%之间,并呈逐渐扩大趋势。这种负的效应随着发展和改革的历程有明显的波动趋势;把总效应分解为工资差异效应和部门份额效应以后,显示中国当前的劳动力错配对TFP产生的负效应主要是由于部门间的工资差异所致。

Dynamic land use and land cover changes and their effect on forest resources in a coastal village of Matemwe,Zanzibar, Tanzania

Recent land cover change estimates show overall decline of tropical forests at the regional and global scales caused by multiple social, cultural and economic factors. There is an overall concern on the prevailing land use practices, such as shifting cultivation and extraction of forest materials as agents of forests losses, but also new, emerging land uses are threatening tropical forests. Understanding of the long-term development and driving forces of forest changes are needed, especially at local levels where many decisions on forest policies and land uses are made. This paper addresses the importance of such information for improved estimates of forest dynamics by studying local level land cover and land use changes during the last 50–70 years in the Eastern African tropical island of Zanzibar, Tanzania. The paper discusses the role of traditional and new land uses mainly subsistence farming, tourism and government interference through tree planting, in the long-term development of the forests at the village level. The material for the study is gathered from the interpretation of archival maps and aerial photographs combined with contemporary digital aerial photographs. The analyses are based on the mapping, spatial sampling and spatio-temporal change trajectory analysis (LCTA) of forest land cover, forest land uses and settlement patterns with GIS and statistics. Six distinct forest land cover change trajectories were identified and these illustrate dynamic and heterogeneous nature of the forests. Closed forest cover has dominated throughout due to cyclical land use patterns, but over 70% of the land area has been continuously transforming between closed, semi-open and open land cover conditions. Land use turnover rates indicate that hardly any forest areas are left untouched from the forces, which remove and re-establish forest vegetation in the long run. Land cover and land use change trajectories are spatially fragmented in the studied landscape. Majority of forest loss-gain dynamics is caused by shifting cultivation, while forest losses are most dramatic along the coast, where traditional and new land uses meet and land uses pressures are highest. The study suggests that landscape change trajectory analyses, where contemporary and historical information on land uses and land cover changes are spatially linked, can provide valuable aspects into local level forest land use planning and management strategies. For the case study, the findings suggest the following key forest management strategies for consideration: (1) establishment of a protected forest/scrubland in participation with the local stakeholders, especially the farmers, (2) promotion of areas for permanent agricultural practices, while simultaneously introducing management controls in the traditional slash-and-burn farming areas, and (3) promoting new livelihood opportunities for the farmers, who have traditionally been dependent on forest resources, meanwhile introducing alternatives for fuel wood for cooking.
