Covid-19-tested food labels

While the transmission of virus SARS-CoV-2 via food is rare, some Chinese food retailers are considering a Covid-19-tested food label. However, how consumers may support such a label is unknown. We quantify Chinese consumers’ willingness to pay (WTP) for food carrying a Covid-19-tested label using an online choice experiment. We find that the WTPs for such a label are always positive for all food products considered. The amount of WTP depends on the entities authenticating the labels, country of origin of the food, and consumers’ socio-demographic status. Contrary to expectation, the knowledge on Covid-19 does not affect consumer preferences for the Covid-19-tested food labels. Our benefit and cost analysis suggests a possible large benefit of creating and administering a Covid-19-tested food label. This study provides insights for policymakers, global food manufacturers, and retailers to create marketing strategies to alleviate consumer food safety concerns associated with Covid-19.

Dialectical mind can be sweet toward crisis‐associated products/brands

Consumers’ thinking style (e.g., dialectical thinking), which is fundamental to cognition, has been paid inadequate attention in the consumer literature. This research explores the impact of dialectical thinking on Chinese consumer responses toward crisis‐associated products/brands. Findings in three experimental studies indicate that, in comparison to those primed with nondialectical thinking, consumers primed with dialectical thinking report higher levels of purchase intention and trust for a crisis‐associated product/brand. This is the case not just for products with Chinese cultural background, but also for products with western cultural background. Consumers’ perceived severity of crises moderates the impact of dialectical thinking, with a stronger impact in a highly severe crisis situation than in a less severe one. A survey study indicates a similar pattern. These findings are important in suggesting ways of encouraging Chinese consumers to be insistent on quality standard in order to better protect their consumer rights, and moreover, for multinational corporations on how best to respond and formulate strategies of handling product‐harm crises in the Chinese market.     

衡水市农户土地资源转出意愿的影响因素与行政干预

[目的]通过了解河北省衡水市农户土地转出的意愿状况,分析影响农户土地资源转出意愿的关键因素,并制定正确的战略决策,为构建农地适度规模化经营奠定理论基础,促进衡水市农民的现代化发展。[方法]文章结合调研情况,对样本区农户土地使用权流转行为进行了统计描述和分析研究,并运用Logistic模型对农户土地使用权转出意愿的影响因素进行了分析,找到了影响衡水市土地流转的关键性因素。[结果]研究表明,户主年龄、从事职业和文化程度、农户家庭非农收入以及农户家庭兼业人数等与农户土地转出意愿呈显著正相关关系,显著性数值分别为0. 018、0. 000、0. 010、0. 000、0. 028,而农户家庭农用机械数量则与农户土地转出意愿呈显著负相关关系,显著性数值为0. 033。此外农户社会保障程度和农户对政府土地流转的相关政策了解程度等因素也影响着农户土地流转的意愿。[结论]影响农户土地转出意愿的显著性因素包括家庭非农收入、户主年龄和职业;另外,户主的年龄、职业、文化程度、非农收入、家庭兼业人数和农用机械数量均是影响农户土地转出意愿的重要内容。     

Institutional quality,investment efficiency,and the choice of public–private partnerships

We examine a sample of 625 public–private partnership (PPP) firms from 1980 to 2015 that straddle nine countries with varying degrees of economic development and PPP markets. We find that the motivations of the firms that undertake PPP investments vary. While private sector firms in economies with low institutional quality choose to engage in PPPs to alleviate capital constraints attributed to underinvestment, those in economies with high institutional quality participate in PPPs to solve the problem of overinvestment due to an abundant cash flow. In the long run, the benefits of lower capital constraints through PPP investments are more pronounced in economies with high institutional quality.     

Neither an Authentic Product nor a Counterfeit: The Growing Popularity of Shanzhai Products in Global Markets

Counterfeits have been a longstanding concern to global brand manufactures. However, recently, a new product category that partly imitates and partly innovates under the term shanzhai has entered into market. Shanzhai products mimic original leading brands through visual or functional similarities and may also provide additional features. Given this new copycat phenomenon, our study for the first time conceptually distinguishes shanzhai products from counterfeits, theoretically compares the values of consumers choosing shanzhai products versus counterfeits, and empirically tests such differences in one integrative model. Specifically, shanzhai buyers value product functional benefits more than counterfeit buyers, while counterfeit buyers value status consumption, yet experience less self‐clarity than shanzhai buyers. Our findings offer important implications for imitative innovation literature as well as for practitioners.     

Public pollution abatement and wage inequality

This paper constructs three-sector general equilibrium models to investigate how public pollution abatement affects the skilled–unskilled wage inequality. In the basic model with full employment, we find that a higher degree of public pollution abatement will decrease the wage inequality if the intensity of skilled labor in the urban skilled sector is sufficiently large and expand or narrow down the wage gap if this intensity is sufficiently small. In the extended models, we consider other four cases, and obtain the results similar or dissimilar to that of the basic model.     

进城务工提升了农民的获得感吗——基于中国家庭追踪调查数据的实证分析

持续增强人民群众的获得感是我国新时代民生事业建设的重要任务.农业劳动力向城市转移显著提高了农民的收入水平,增加了农民在物质层面的获得感,但其对农民精神层面获得感的影响尚不清楚.基于中国家庭追踪调查2016年收集的调研数据,利用倾向得分匹配(PSM)与反事实分析方法的实证评估结果表明,进城务工就业不仅提高了农民收入,而且提升了农民对收入水平的主观感受及其对生活的满意程度,并且使得农民对未来更加充满信心,然而进城务工并没有提升农民对其社会地位的主观判断.对于那些没有选择进城务工的农民,务工就业甚至可能会降低其对生活的满意程度及对其社会地位的主观判断.尽管进城务工就业从总体上对提升我国农民的获得感起到了重要促进作用,但是对不同特征农民获得感的影响有着明显的异质性.

Structural estimation of behavioral heterogeneity

We develop a behavioral asset pricing model in which agents trade in a market with information friction. Profit‐maximizing agents switch between trading strategies in response to dynamic market conditions. Owing to noisy private information about the fundamental value, the agents form different evaluations about heterogeneous strategies. We exploit a thin set—a small sub‐population—to point identify this nonlinear model, and estimate the structural parameters using extended method of moments. Based on the estimated parameters, the model produces return time series that emulate the moments of the real data. These results are robust across different sample periods and estimation methods.
