Crowdfunding and social influence: an empirical investigation

The literature so far provides no in-depth investigation of the determinants of decisions to contribute to crowdfunding platforms. The present article draws on work measuring the decisions and prosocial behaviours of individuals in relation to public goods, and uses survey data on crowdfunding behaviour. We surveyed an original sample of individuals in France to explore individual decisions and amounts of funding chosen to support a creative project. We show that in non-equity crowdfunding contributing money is associated with altruism. Our findings suggest that the ‘warm glow’ effect influences the level of the contribution; we show also those monetary incentives could ‘crowd out’ the decisions to contribute of crowdfunders. Our study has some implications for business strategy since understanding why people contribute adds to our knowledge about the incentives that might encourage them to increase their contributions, and allows predictions about how changes to how crowdfunding platforms are managed might affect individual incentives to give.

An Evaluation of Inertia Models of Unemployment

Two approaches have been used to model unemployment. The first, conventional, approach involves linking the unemployment outcome to observed indices of productivity, structural factors and discrimination such as educational attainment, location and birthplace. The second approach, the inertia model, involves using a person's labour market history as a way of including in unemployment models information on the 'unobservables' that influence employability. This paper evaluates the performance of both models of unemployment. The results provide unambiguous support for the inertia model when modelling unemployment. The inertia model has higher explanatory power, higher within-sample prediction rate success and fewer out-of-sample forecasting errors than the conventional model. The estimates from the inertia model can be used to provide quite accurate predictions of the risk of becoming unemployed. This is important if individuals at high risk of becoming unemployed are to be targeted for labour market assistance.     

宪政视野下的司法独立——基于中外宪法文本的比较研究

宪法是国家制度设计的蓝本,是宪政理念最直接的体现,是司法独立的一面镜子,更是实践司法独立思想的首要制度保障。司法独立思想来源于古希腊政治哲学家的宪政思想与分权制衡的理念,它具有三大特征：司法权独立,法院独立和法官独立。就司法权力的独立而言,主要西方国家有两大特征：一是设置了专门行使司法权力的机构;二是明确规定了司法权力的独立行使范围。1949年以前,我国宪法文本对于＂司法制度＂的设计与西方国家存在着很大的相似性,有几个宪法文本就是学习与借鉴英美国家来制定的。1949年建国以后,我国宪法文本中对于＂司法制度＂的设计也与之前的风格迥异。     

Tourist Satisfaction and Destination Image of Vietnam's Ha Long Bay

Although considerable work has been done on destination image as a whole, far less research has investigated the differences in destination image assessments for domestic versus international visitors in developing countries. This study offers findings that illustrate the differences in perception of destination image, satisfaction attributes, and intention among domestic and international visitors to Ha Long Bay, a United Nations Educational Scientific and Cultural Organization World Heritage Site in Vietnam. The results of a survey on 650 tourists suggest that international visitors to the Ha Long Bay region have higher standards and are more critical in their evaluation of services than domestic visitors when judging this destination. Destination image is a common factor determining the level of satisfaction of both groups. Basic and augmented services were found to influence international visitors’ future intention toward the destination. This finding implies that the destination managers of Ha Long Bay need to improve current standard of augmented services to yield higher visitors’ propensity to recommend and return to the destination.     

基于生态足迹模型的沿海城市可持续发展分析——以大连市为例

根据《大连统计年鉴》等相关资料,利用生态足迹模型,对大连市2004—2008年生态足迹进行计算和分析;并计算出大连市这五年的万元GDP生态足迹和社会发展能力指数。利用这些指标分析大连的可持续发展情况,并提出相应的对策。结果表明：大连这五年的平均生态赤字为4.3184hm2,说明大连的区域生态系统正面临过度开发的压力;生态足迹多样性指数五年均低于中国平均水平,意味着大连生态经济系统生态空间分布很不均匀;社会发展能力指数高于中国平均水平和万元GDP生态足迹大体处于减少状态,说明大连在经济社会发展的同时,资源利用率也在不断地提高。     

Traders' Bidding Strategies on European Grain Export Refunds: An Analysis with Affiliated Signals

Using a multivariate distribution of traders' information with correlations, we specify the traders' bidding strategies on tenders of European soft wheat intervention stocks. We show that correlations may have opposing effects on the traders' bidding strategy, depending on their valuation of the grain. This structural approach allows us to estimate the traders' strategies using generalized method of moments procedures.
