Valuing customers for social network services

In the current Internet environment, many online service companies based on community factors (networks) produce and sell new types of digital products. For example, SNS (social network service) companies now sell customers digital decorative products for the adornment of online avatars. Not only do individual customers consume these digital products, but they also exchange them as gifts in their local neighborhoods. While previous studies on customer valuation (e.g. CLTV, RFM, etc.) focus on some important issues for identifying valuable customers, the literature does not resolve issues related to the effects on customer value of products purchased as gifts for another person. This study attempts to verify empirically the effects of two representative social network properties (tie strength and the number of ties) on customer monetary value.This study selects 2615 customers from a South Korean SNS website who enrolled on the site on the same day. Data include diverse purchase-related information, social network properties in terms of gift-giving for six months, and demographic information. The primary results of this study are as follows. First, the proposed model, which includes social network properties, has a great deal more explanatory power than the baseline model — the RFM-based customer value model. Second, tie strength and the number of ties in a gift-giving network increase customer value. Third, tie strength has a more profound impact on customer value than does the number of ties. The results of this study theoretically expand the domain of customer valuation studies due to the inclusion of social network properties, and suggest important practical implications for some online SNS companies in their efforts to find valuable customers and improve customer value.     

Industry changes in technology and complementary assets and the creation of high-growth firms

This study uses employment data to examine why some industries host more new high-growth firms than others. Using a unique data base of 201 industries over a 15-year period, we find that increases in the proportion of employment of scientists and engineers in industries are positively associated with counts of fast-growing new firms; however, we do not detect a relationship between fluctuations in the proportion of employment in sales and production occupations and counts of fast-growing new firms. The findings suggest that technological innovation is an important determinant of entrepreneurial opportunity. Further, they suggest that private new firms are an important means of organizing commercial innovation and that new firms may be less constrained by complementary assets than has been previously understood.     

关于我国保险公司履行社会责任的综合评价——基于利益相关者理论的视角

Incorporating annoyance in airport environmental policy: noise, societal response and community participation

Airport capacity continues to be one of the air transport issues that creates the most concern. The major environmental constraint for airports is the noise generated by aircraft. Annoyed communities living around airports have become a limiting factor for airport capacity and operability. This paper brings together the existing literature in the fields of airport environmental capacity, non-acoustic factors of noise annoyance, NIMBYism and environmental conflicts. We also analyze the socio-environmental conflict between Barcelona airport and the community of Gavà Mar. This case shows that the lack of trust between parties, the impossibility of predicting noise exposure, the absence of opportunities for civil society to speak and the difficulty of accessing relevant information foster annoyance and mobilization in the communities that live around the airport. In addition, it is shown that, in such a situation, communities’ reactions can evolve to a post-NIMBY stage in which proactive attitudes replace reactive ones.     

Diminishing effects of location? Some evidence from Swiss municipalities, 1950–2000

This paper analyzes how location has affected, in the second half of the twentieth century, the population growth of 2889 municipalities in Switzerland. The analysis demonstrates the temporal relativity of location attributes, even for small territorial divisions, such as the Swiss cantons. However, we also show that, both absolute and relative location attributes have weakened over time as population growth predictors, apparently due to improving road infrastructures, and growing motorization. The study has been made possible by a detailed historical population and accessibility database available for Swiss municipalities. To the best of our knowledge, no database of such scope and quality is available for any other European country.

分工演进与土地承包经营权股份化——一项土地股份合作社的调查及政策启示

在土地要素市场发育仍不完备的情况下,当前农村出现了大量的土地股份合作社,而大多数研究却忽视了土地要素市场与土地股份合作之间的异质性和替代性。一项来自江苏省苏中地区的调查表明,农民的职业分化为农户间分工合作提供了可能,家庭内部成员间的代际分工或性别分工推动了土地股份合作的发展。研究发现,农民从分工演进、合作及规模经济中的获益大于单纯的土地市场流转收益,从而使上述替代具有了理性的基础。于是,农民达成供给制度、组织创新的集体行动,以重复合作形式的稳定预期降低一次性合作的交易费用,以内部化的经济组织治理替代市场流转。
