新冠肺炎疫情对线上商品价格变化的影响

文章运用电商高频价格大数据,分析了新冠肺炎疫情对商品价格变化的影响。研究发现:根据公平定价理论,在突发疫情下商家会加入消费者情绪制定价格策略,商品价格经过调整后趋于稳定;并且,商品价格表现出较低的价格黏性,对称的交错调价使得新冠肺炎疫情对商品价格的冲击有限。因此,政府部门可利用线上商品价格编制大数据物价指标,及时反映市场供求变化,促进资源优化配置,为宏观政策制定提供依据;同时,加快推进消费数字化转型,优化线上交易环境,建立预警机制来应对突发情况。     

网络直播购物情境下的拟剧化营销——基于抖音直播平台的分析与诠释

试论消费税税制改革与完善

目前,消费税成为世界各国广泛研究的课题,在税收政策中扮演越来越重要的角色。我国自1994年1月开始征收消费以来,消费税收入从514．07亿元增长到1634亿元,翻了3倍。但是,由于消费税是一个与社会发展同步的税种,同时我国的消费税税制处于发展的初级阶段,现行消费税税制还存在一些问题。2006年4月1日,我国对消费税税制做了一次重大的调整,是自实行消费税以来第一次重大变革,为以后的进一步完善消费税指明了方向。     

Advertising, Its Determinants, and Market Structure

This study derives a formal model of firm advertising behavior and applies it to the industry level to figure out the relationship between advertising and market structure. The firm advertising model shows that both consumer preference andfirm-specific advertising competence jointly determineprofit-maximizing advertising intensity. At the industry level, advertising intensity is represented multiplicatively by consumer preference and a measure of market structure, which reflects the joint distribution of the levels of advertising competence and market shares among firms. The new market structure measure suggests that those single-dimensional measures of market structure such as seller concentration and the Herfindahl index are inadequate in explaining interindustry differences in advertising intensity, and that the long-debated advertising-concentration relationship differs depending primarily on the appropriability of advertising. An empirical analysis of 426 five-digit Korean manufacturing industries shows that an inverted U-shaped relationship between the Herfindahl index and industry advertising intensity is observed for consumer goods industries but a lazy J-shaped relationship for producer goods industries.     

Consumers’ valuation for food traceability in China: Does trust matter?

Food safety is a very important topic in China. We investigate Chinese consumers’ preferences and willingness to pay (WTP) for food traceability using a choice experiment. Given that consumers’ trust in the food system may affect their preferences and WTP, we also assess the interaction between consumers’ trust in government’s supervision of food safety and food labels and consumers’ preferences for traceable food products. Using data collected from a choice experiment on Fuji apples in a face-to-face survey in six Chinese cities, the results show that (i) consumers are willing to pay for traceable food but their valuations can differ upon the degree of their trust in government’s supervision of food safety and food labels; (ii) consumers are willing to pay for traceability with strong evidence of preference heterogeneity; (iii) government is not the most trusted safety inspection and certificate authority as found in prior studies using animal food products in China.

Reward meritocracy or nepotism: The case of independent financial advisors appointed by Chinese listed companies

As independent financial advisors, securities firms are the core intermediaries in major asset reorganization (MAR) of listed companies. Furthermore, they play the dual roles of transaction and authentication. Based on this institutional background, this paper studies how listed companies choose between industry experience (“meritocracy”) and relationships (“nepotism”). Using the MAR of A-share listed companies from 2008 to 2013 as the sample, this paper shows that higher transaction costs (i.e., greater demand for the transaction function of advisors) are related to the higher possibility of advisors with weaker relationships and more industry experience being hired. It also shows that higher suspicion of tunneling (i.e., greater demand for the signal of fairness associated with advisors’ authentication function) is related to the higher possibility of advisors with weaker relationships being hired, but it is not significantly related to whether advisors have more or less industry experience. This paper also shows that reputation has a certain governance effect on the negative consequences of relationship. For the most part, listed companies reward meritocracy but not nepotism when appointing independent financial advisors.     

深化资本市场中枢作用研究

资本市场应当主导我国金融市场由资金配置向资本配置转型、由不动产金融向动产金融转型,同时主导我国生产要素市场化改革。资本市场在经济活动中发挥主导作用的关键在于提升其价值发现能力,而当前我国资本市场价值发现能力欠缺有多方面深层次原因:一是对资产和资金的包容和汇聚不够,二是资本的流动和配置受到制约,三是定价机制受到一定程度的扭曲,四是产权制度不完善,五是市场主体归位尽责情况不理想,六是金融衍生品市场不够成熟。本文建议:一是完善多层次资本市场建设,二是推动市场多空机制均衡发展,三是纠偏资本市场定价机制,四是加速完善现代产权制度,五是强化对市场各主体的培育,六是加强资本市场高质量对外开放。     

Even beyond humanity – a comment on ‘Change and commitment: beyond risk and responsibility’ by Silvio Funtowicz and Roger Strand

Due to past major food scares, food-safety perceptions have become a widely investigated topic. The aim of the present study was to examine food-safety perceptions separately for every step of the total meat supply chain, as such a detailed approach yields more promising strategies to ensure food safety in the future. Using a large-scale survey, we examined people’s risk perceptions of 18 steps describing the total meat supply chain. The results revealed a clear distinction between risk perception at the production stage and risk perception at home in the total meat supply chain, in that people perceived significantly less risk at home. However, people’s risk perceptions of the single stages in the total meat supply chain were overall slightly above average. Additionally, there were individual differences, as risk perception at the production stage was highly correlated with risk perception at home, meaning that some people perceived more risk than others overall. Using a multiple regression analysis, we found food-safety perceptions to be barely significant next to other important variables affecting people’s meat-consumption decisions. For those analyses, we asked participants to assess several constructs previously found to be associated with meat consumption. The goal was to determine how food-safety perceptions influence people’s meat consumption next to other important constructs in situations in which no major food scandal is present. The present paper concludes by discussing possible marketing and policy strategies to overcome people’s inaccurate safety perceptions of the stages of the total food chain.     

Marriage between credit cards and the Internet: Buying is just a click away!

This paper examines whether Internet access positively affects credit card balances. To that end, we compare the 2010 and 2013 Surveys of Consumer Finances, analyze the consistency of the results over time, and provide the rationale for any resulting differences. Using the censored techniques, our results indicate that Internet access has a positive effect on credit card balances, which suggests that consumers with Internet access are prone to higher balances compared to those without. The probability of carrying positive balances was larger in 2010 compared to 2013. Overall, the results suggest that, while the financial crisis might have contributed to higher balances in 2010, the economic recovery afterward seems to have eased the burden of credit card debt.
