　　讲座题目：清代粮食市场整合的空间范围——来自第二次金川之役自然实验的证据

　　摘要：市场整合和发育被视为经济发展的重要前提条件，一直是前现代社会研究中的重要话题，其中交通成本被认为是当时市场整合程度最为重要的决定因素。然而已有研究因无法控制地区间异质性和共同冲击影响，不能很好地识别出交通成本的影响大小。乾隆朝第二次金川之役发生在既靠近粮食产区又因高山阻隔而不能直接影响后者的嘉绒藏区，成都和雅州作为粮食运送前线的两个唯一入口，因而成为战时的粮价中心。战争的补给多采用市场运作，鼓励商人参与粮食采购和运输，交通成本遂成为两地粮价差的重要决定因素。两个因素的结合使得粮价在战争期间随距成都和雅州的距离递减。本文利用第二次金川之役这一自然实验，估计了清代交通成本对粮价的影响。结果表明每一百公里价差超过3.1%会引起两地间通过陆路实现粮食流动，每一百公里价差超过1.6%能引起两地间通过水路实现粮食流动，这些跨地区的套利价差决定了清代粮食市场整合的空间范围。

　　讲座题目：Corporate Tax Benefits from Politicians’ Hometown

　　摘要：This paper investigates the impact of the geographic coincidence of firms and political leaders on corporate tax benefits. Taking advantage of a unique tax disclosure rule in China, which allows us to identify firm-specific tax benefits, we find that firms enjoy more favorable tax treatments if their registered city is the incumbent provincial leader’s hometown. This result is not driven by quid-pro-quo exchanges and informational advantage of the political leader. However, the effect is attenuated when the leader has stronger promotion incentives. Moreover, we show heterogeneities in the effect of hometown connection on corporate tax benefits in terms of the cost-benefit trade-off. Overall, our study sheds light on how the social identity of politicians engenders tax benefits for business entities.

　　讲座题目：Impulse balance and framing effects in threshold public good games

　　摘要：In this paper we revisit the evidence for framing effects in threshold public good games. Our particular focus is on why the probability of providing the public good appears to be higher in positive, give frames compared to negative, take frames. We show that impulse balance theory can explain this effect. We also report on a new experiment designed to test the predictions of impulse balance theory. The results of the experiment fit well, both in quantitative and qualitative terms, with our predictions.

　　讲座题目：The Interactions between Endowment and Environment: Evidence from a Social Experiment on Twins

　　摘要：Does endowment moderate the effect of environmental adversities? This question has profound implications for income inequality, but few studies provide a clean identification of the endowment-environment interaction. We explore a social experiment, i.e., China's send-down campaign, and birthweight differences in genetically identical twins to obtain exogenous variations in environment and endowment, respectively. The send-down campaign forced millions of Chinese urban youths to do hard agriculture works in rural areas during China's cultural revolution. We find that the send-down experience strengthens a child with a higher endowment relative to the one with a lower endowment. If the higher endowed male was sent down to the countryside, he earns higher wage, attains more years of schooling after send-down, marries a better educated wife, and receives more wedding gifts from his parents. By contrast, we do not find a robust endowment-environment interaction for females. Our findings imply that adverse environmental shocks tend to enlarge income inequality.

　　讲座题目： Winter is Coming: Early-life Experiences and Politicians’ Decisions

　　摘要：The preferences of politician matter in policy-making. This paper focuses on the role of local politicians’ early-life experiences in their policy decisions in office. We exploit the China’s Great Famine from 1959 to 1961 as a natural experiment and examine the fiscal decisions of those county Party secretaries who experienced the famine in early childhood. The results indicate that if the secretary experienced a severer famine that decreased the agricultural population by 10% during their early childhood, other things being equal, they will spend 6.8% more on agriculture and 10.6% more on social security. Moreover, a 10% severer famine experienced during their early childhood decreases agricultural tax by 38.8% and VAT by 5.6%. Further, the long-term impact of secretaries early-childhood exposure to the famine comes from the preference formation, instead of their beliefs about future similar events. Counterfactual experiments suggest that these preferences changes have substantial influence on Chinese agriculture. To examine the channel of famine effect, we exploit the household survey data with a particular focus on Communist Party members. Analyses show that famine experience changes their relevant attitudes significantly.
