农民的土地产权偏好及其影响因素研究

利用2005年全国城乡居民生活综合研究中的农村数据,分析了农民的土地产权偏好及其影响因素。从偏好的分布来看,有37.2%的农民偏好土地调整,而62.8%的农民偏好稳定的土地产权,但他们对永久土地使用权的偏好(23.9%)并不太强烈。农民的土地产权偏好主要受个体、家庭和社区三类解释变量的影响,从研究结果来看,土地情结说难以成立,而政策变量的影响不确定;理性小农的特点虽然明显,但不能解释全部;村庄社区变量对农民的偏好有重要影响,但呈减弱的趋势;区域因素也会影响农民的偏好。因此,在较长时期内,土地调整的压力依然很大,但在农民认同、规则明确的条件下,村组内部的土地调整与产权稳定可以相容。     

Regional airport choice: Consumer behaviour and policy implications

The analysis of origin airports in multi-airport regions has a well established tradition in transportation and regional economics. The main goal of the paper is to estimate the importance of the different attributes that determine origin airport choice. In our case we adopt a stated preference approach to study this problem and evaluate the effects of possible policy interventions. We also perform a detailed segmentation of the sample studied according to the socio-economic variables that prove statistically relevant when interacted with the attributes used to characterise airport choice. Moreover, in order to test for the presence of heterogeneity in agents’ preferences we estimate several mixed logit models with different specifications, including heteroscedasticity and error component. With respect to previous studies we develop and extend the traditional SP approach by also analysing the role and relevance of attribute cut-offs in this research field. The policy simulations produced are based on the estimation of airport-specific attributes. The study concentrates on a multi-airport region in central Italy where four competing airports are located.     

农村区域性公共品有效供给的新视角——基于浙江村级公共品供给的调研

实现农村公共品有效供给一直是三农问题关注的焦点,而且政府承担着主要的供给责任。对于具有需求偏好差异的农村区域性公共品而言,政府完全主导的供给模式却是导致效率损失的主要原因。正是基于这一点考虑,并结合浙江省村级公共品的调研,本文提出实现农村区域性公共品有效供给的新模式———政府诱导供给模式,即通过税收惠免、财政奖补等激励政策,诱导私人或村集体积极参与农村区域性公共品供给,弥补县级政府效率损失。     

Premium auctions and risk preferences: An experimental study

In premium auctions, the highest losing bidder receives a reward from the seller. This paper studies the private value English premium auction (EPA) for different risk attitudes of bidders. We explicitly derive the symmetric equilibrium for bidders with CARA utilities and conduct an experimental study to test the theoretical predictions. In our experiment, subjects are sorted into risk-averse and risk-loving groups. We find that revenues in the EPA are significantly higher when bidders are risk loving rather than risk averse. These results are partly consistent with theory and confirm the general view that bidders' risk preferences constitute an important factor that affects bidding behavior and consequently also the seller's expected revenue. However, individual subjects rarely follow the equilibrium strategy and revenue in our experiment is lower than in the symmetric equilibrium.     

A strict expected multi-utility theorem

This paper integrates two key approaches to the representation of incomplete preferences over lotteries. The main result strengthens the conclusion of the expected multi-utility theorem in Dubra, Maccheroni, and Ok (2004) by ensuring that all utility indices involved are Aumann utilities (i.e., yield a strictly increasing expectation). The advantages of the method are demonstrated by parametrizing maximal elements and by providing a novel characterization of Aumann utilities.     

The Significance of CSF Among Enterprises in Latvia： An In-depth Analysis

The present research paper is dedicated to the in-depth analysis of the significance of critical-to-success factors （CSF） among enterprises in Latvia. The goal is to distinguish and find key success factors of Latvian companies who survived the economic crisis, which started in 2008, and executed the enabling objectives of the paper. Research methodology involves the analysis of the existing theoretical literature, in-depth interviews with the top management representatives of large Latvian business entities were interviewed by GFK （Custom Research Baltic agency） on behalf of the authors of the paper. It is found out that 10 largest industries for the big companies are： fuel retail and wholesale, energetics, food retail and wholesale, chemical products, logistics, metal processing, financial services, information technologies service and production, passenger transportation, and telecommunication services. For medium companies such industries are： food retail and wholesale, logistics, fuel retail and wholesale, wood processing, automotive industry, construction, financial services, pharmaceutical products, metal processing, and beverage wholesale and production. The authors also scrutinised 72 articles of 38 Forbes magazine archiving from the years 2010-2014. Thirty CSF were defmed. The most significant CSF according to the Forbes interviews are specific market niche, export, technological innovations, and high quality of products and services. The in-depth interviews with the top management representatives prove the importance of the above mentioned factors. Relevant recommendations are provided in the end of the paper.     

基于个体差异的报童群体决策研究

通过实验研究群体决策和大五人格对报童订购的影响。研究表明大五人格中开放性维度能很好地预测个体和群体决策者的订购行为。在个体实验中，开放性越高的个体更不易产生锚定效应，其他四种人格特性与锚定偏差无显著关系；在群体实验中，群体的开放性得分均值、群体中高开放性成员所占的比例与锚定偏差呈负相关关系。通过比较两种实验结果，发现群体锚定倾向明显小于个体锚定倾向，而群体决策并没有优于个体决策。该研究结果对企业人员招聘、构建决策团队及降低决策偏差有一定参考价值。     

Estimating the Private Economic Benefits of Sons Versus Daughters in India

In order to understand the economic incentives behind gender discrimination in India, this paper provides the first estimates of the magnitude of the economic benefits of having a son instead of a daughter. The study estimates large gains from a first-born son to per capita income and expenditure, household assets, and a reduction in the probability the household is below the poverty line. Estimates show that a first-born son may provide economic advantages through a reduction in total children born and also from an adult son’s labor supply contribution to his parents’ household. The observed pattern of incentives is also compared with observed patterns in sex selection as a test of whether the relative economic value of first-born sons and daughters can explain the prevalence of sex-selective abortion.     

国际金融危机下完善中小企业税收优惠制度的法律思考

税收优惠是国家在税收方面给予纳税人和征税对象的各种优待的总称。在中国,99%的企业是中小企业。长期以来我国都有关于中小企业税收优惠的规定,从而促进了中小企业的快速发展。此次国际金融危机使我国中小企业的发展面临严峻挑战,保护中小企业迫切需要税收优惠政策的支持。完善中小企业税收优惠制度,对于帮助中小企业顺利度过难关,促进国民经济发展,维护社会稳定均有重大意义。本文通过借鉴当前金融危机形势下各国关于中小企业税收优惠制度的调整经验,对我国现存相关立法进行了全面剖析,并就完善该项制度提出几点建议。     

A lottery-preference-based explanation of realized kurtosis puzzle in Chinese stock market

High kurtosis corresponds to fat tails on both sides and under risk-aversion assumption investors’ dislike of left-tail loss outweighs their preference for right-tail gain. Therefore, high kurtosis characteristic of stock should predict high expected returns. However, the high-frequency-data-based empirical results on Chinese stock market are just the opposite, which we refer to as the ‘realized kurtosis puzzle’. Using the double sorts and firm-level cross-sectional regression methods, we further demonstrate investors’ preference for lottery-like stocks or lottery preference is key to solve the puzzle. Our further empirical research verifies stocks with higher retail investors’ shareholding proportion and unavailable for short show stronger ‘realized kurtosis puzzle’. In addition, the puzzle is particularly significant in high lottery preference periods while less apparent in low lottery preference times.
