摘要:
In a divided world, political identity can heighten the prevalence of heuristics in decision making. This study explores how political identity influences the conjunction fallacy in risk attitudes, whereby people prefer betting on a combination of two events rather than one of the two events, thus violating the basic law of monotonicity. In the context of the 2024 U.S. presidential election, we examine individual risk attitudes towards upcoming election outcomes and economic conditions a year later, both separately and in combination. Using a representative sample from the U.S., we find that people are more likely to exhibit conjunction fallacy in risk attitudes in congruent scenarios for the Democrats, whereby a Harris victory aligns with good economic conditions and a Trump victory coincides with bad conditions. Additionally, we measure individual beliefs about these events and demonstrate that the conjunction fallacy in beliefs partially contributes to the fallacy in risk attitudes. This study highlights the significant role of political identity in shaping preferences and beliefs.

摘要:
Using a randomized experiment with 3379 parents of high-school students in China, I identify two channels of social influence in parents’ decisions on children’s educational investments: parents adjust their decisions based on other parents’ behaviors because they learn from other parents’ decisions (“social learning”) or because their children are facing competition from peers (“competition externality”). I find that both channels have statistically significant effects on parents’ investment decisions and increase their willingness to buy an educational service by over 20%. Although the average effects of the two channels are not statistically different, the main channels of peer effects are heterogeneous by parents’ educational background: parents with higher education are more likely to learn from peers’ decisions whereas those with lower education are mainly incentivized by the competition externality. These results also shed light on the mechanisms underlying the herding behavior and involution in other settings with competition, such as competitive sports.

摘要:
Sellers on a two-sided platform have positive market size effects (externalities) on each other by bringing customers to the platform. Platforms can take advantage of such effects to charge greater prices to the sellers. In this paper, we set up a structural model of such two-sided markets, where the consumers choose sellers, the sellers compete on the prices, and the platform negotiates with the sellers. We apply the model to a unique dataset of stores in shopping malls. Using information on store-level rental contracts and customers for 15 shopping malls in Shanghai, we find that the market size effects differ significantly by store category. In addition, the stores' bargaining power against the malls increases with the store size and floor level. Our counterfactual analysis considers the trend of offline retailers closing due to the growing retail industry. We find that the shopping malls could earn greater rents if retail stores are turned into other categories.

摘要:
本研究基于保险公司年度信息披露报告等有关公开数据,运用主成分分析、聚类分析、熵分析等数学统计方法对中国保险公司竞争力与投资价值进行评价研究。首先在定义竞争力、投资价值等有关概念的基础上,建立多层次指标评价体系,最后分别给出中国人身保险公司、中国财产保险公司的竞争力排名与得分,以及人身险公司与财产险公司的投资价值金额;并从公司与指标两个角度分别对中国人身险公司与财产险公司的竞争力评价结果进行了稳健性检验。检验结果表明,公司的竞争力排名不依赖于部分指标或者部分公司(10%到15%左右)的取舍,评价结果是稳健的。
