转基因标签的消费者维度思考

本文从消费者角度分析了现行转基因标签政策实施过程中存在的成本转移、道德风险等等被忽视的问题．并以我国包装大豆色拉油市场为例，利用垂直差别化模型对加贴转基因标签前后消费者经济福利进行了比较。     

中国古代的和谐思想与构建和谐社会

中国传统文化源远流长、博大精深,其中有关"和谐"的思想非常丰富,如保合太和,以和为贵,天人合一,致虚静、道中庸,等等.这些思想既是中国传统文化的精髓和被认同的人文精神,又是今天我们实现社会和谐,构建和谐社会的重要思想资源.本文主要是从人总是生活于人与社会、人与人、人与自然、人与自身的四维空间之中,以及目前我国在现代化建设方面遇到的种种挑战的角度来梳理、审视中国古代和谐思想的,这无疑具有一定的历史和现实意义.     

Personality traits,basic individual values and GMO risk perception of twitter users

Abstract

The present study investigates how the most foundational factors to individual differences – personality traits and personal values – affect the perceived safety of genetic modification and their relative importance. Publicly available communication data from 522 Twitter accounts discussing genetically modified foods and their safety was processed in two steps. First, accounts were categorized by the researchers as viewing GM foods as either safe or not safe. Second, using the IBM Watson platform, the Twitter communication data were subjected to lexical analysis to assign scores according to the Five Factor Model for personality traits and Schwartz’s basic individual values to the individual accounts. Logistic regression analyses were performed to determine how perceived GM food safety is linked to personality traits and individual values. Although both traits and values significantly contribute to explaining GM attitudes, personality traits strongly moderate the effect of individual values on risk perception.     

构建关系型营销渠道:一个渠道知识共生网络

在传统的交易营销理念指导下所形成的交易型营销渠道因现代营销环境的改变和关系营销理念的广泛应用,其地位和作用日益受到挑战和限制。因此,在这样的背景下,改革交易型营销渠道,建立以关系营销理念为指导的关系型营销渠道成为企业界和理论界共同关注的一个重要课题。本文首先综述了西方营销渠道关系理论的研究内容,然后在交易型营销渠道与关系型营销渠道比较的基础上提出了一个构建关系型营销渠道的渠道知识共生网络。

Trends in Approval Times for Genetically Engineered Crops in the United States and the European Union

Genetically engineered (GE) crops are subject to regulatory oversight to ensure their safety for humans and the environment. Their approval in the European Union (EU) starts with an application in a given Member State followed by a scientific risk assessment, and ends with a political decision‐making step (risk management). In the United States (US) approval begins with a scientific (field trial) step and ends with a ‘bureaucratic’ decision‐making step. We investigate trends for the time taken for these steps and the overall time taken for approving GE crops in the US and the EU. Our results show that from 1996–2015 the overall time trend for approval in the EU decreased and then flattened off, with an overall mean completion‐time of 1,763 days. In the US in 1998 there was a break in the trend of the overall approval time. Initially, from 1988 until 1997 the trend decreased with a mean approval time of 1,321 days; from 1998–2015, the trend almost stagnated with a mean approval time of 2,467 days.     

The Costs of Coexistence Measures for Genetically Modified Maize in Germany

We estimate the perceived costs of legal requirements (‘coexistence measures’) for growing genetically modified (GM) Bt maize in Germany using a choice experiment. The costs of the evaluated ex‐ante and ex‐post coexistence measures range from zero to more than €300 per measure and most are greater than the extra revenue the farmers in our survey expect from growing Bt maize or than estimates in the literature. The cost estimates for temporal separation, the highest in our evaluation, imply that the exclusion of this measure in Germany is justified. The costliest measures of the ones that are currently applied in Germany are joint and strict liability for all damages. Our results further show that neighbours do not cause a problem and opportunities for reducing costs through agreements with them exist. Finally, we find that farmers’ attitudes towards GM crops affect the probability of adoption of Bt maize. Our results imply that strict liability will deter the cultivation of Bt maize in Germany unless liability issues can be addressed through other means, for example, through neighbours agreements.     

GMO standards,endogenous policy and the market for information

The paper develops a composite index of GMO standards restrictiveness for 60 countries, assigning objective scores to six different regulatory dimensions. Using this index and its components, we empirically investigate the political and economic determinants of GMO regulations for 55 countries, controlling for spatial autocorrelation. Results show that many of the determinants highlighted in the theoretical literature, such as the structure of the agricultural sector and the institutional environment are important determinants of the restrictiveness of the GMO regulation. As a key result there emerges a prominent role of the market for information, showing that the structure of domestic mass media (public vs. private) is an important driver of GMO standards.     

Consumer willingness to pay for redundant food labels

Previous studies, as well as market sales data, show some consumers are willing to pay a premium for redundant or superfluous food labels that carry no additional information for the informed consumer. Some advocacy groups have argued that the use of such redundant labels is misleading or unethical. To determine whether premiums for redundant labels stem from misunderstanding or other factors, this study seeks to determine whether greater knowledge of the claims - in the form of expertise in food production and scientific literacy - decreases willingness to pay for redundant labels. We also explore whether de-biasing information influences consumers’ valuations of redundant labels. An online survey of 1122 U.S. consumers elicited preferences for three redundantly labeled products: non-GMO sea salt, gluten-free orange juice, and no-hormone-added chicken breast. Respondents with farm experience report lower premiums for non-GMO salt and no-hormone-added chicken. Those with higher scientific literacy state lower premiums for gluten-free orange juice. However, after providing information about the redundancy of the claims, less than half of respondents who were initially willing to pay extra for the label are convinced otherwise. Over 30% of respondents counter-intuitively increase their premiums, behavior that is associated with less a priori scientific knowledge. The likelihood of “overpricing” redundant labels is associated with willingness-to-pay premiums for organic food, suggesting at least some of the premium for organic is a result of misinformation.     

On the Coexistence of Banks and Markets*

We examine the coexistence of banks and financial markets by studying a credit market where the qualities of investment projects are not observable and the investment decisions of entrepreneurs are not contractible. Standard banks can alleviate moral‐hazard problems, while financial markets operated by investment banks can alleviate adverse‐selection problems. In competition, standard banks are forced to increase repayments, since financial markets can attract the highest‐quality borrowers. This, in turn, increases the share of shirkers and may make lending unprofitable for standard banks. The coexistence of financial markets and standard banks is socially inefficient. The same inefficiency may occur with the entrance of sophisticated banks, operating with a combination of rating and ongoing monitoring technologies.
