题目:Heterogeneous responses to changes in Physicians' financial incentives: The role of expertise, connection, and rank of patient

摘要:It is well known that physicians respond to financial incentives, which can distort patients’ health care utilization. However, it is less known that how patient characteristics affect physicians’ decision-making. We make use of a natural experiment arising from a drug markup reduction policy to investigate how physicians respond to financial incentives differentially with expert and non-expert patients. With 100% inpatient claim data from a Chinese city, we first document that the policy reduces drug utilization while increases utilization of other forms of care. However, such distortion in care is almost solely borne by non-expert patients. Furthermore, higher-ranked expert patients who work in the same hospital as physicians experience the least distortion in care, followed by same-hospital lower-ranked patients. Non-same hospital experts, who, despite also receiving less distorted care, exhibit healthcare utilization patterns more similar to those of non-experts. These suggest that connection plays a key role in ensuring efficient care in China, administrative rank additionally intensifies such a favorable effect, while medical expertise plays a relatively moderate role.

题目:IPO、本地偏好与家庭股市参与

摘要:IPO对实体经济的影响是学术界和监管层讨论的重点,以往研究大多关注IPO对企业及宏观经济的影响,而忽视了其对资本市场重要参与者即家庭的投资决策的影响。本文基于2013年至2019年中国家庭金融调查数据,从本地偏好视角研究了本地IPO对家庭股市参与的影响。结果表明,本地IPO显著提高了本地家庭参与股票市场的广度与深度,且这一影响在城镇地区、受教育程度较高、收入和财富较多的家庭中更为明显。机制分析发现,本地IPO主要通过提高信息关注度、提升金融素养和提高风险容忍度起到了促进家庭股市参与的作用。进一步地,本地IPO促进家庭参与股票市场投资起到了显著提高家庭财产性收入的作用。本文研究不仅拓展了居民股票市场有限参与的研究视角,也为理解IPO的经济溢出效应提供了微观依据。

学术报告3
题目:Origin of goods and unequal consumer gains from trade liberalization

摘要:Gains from trade depend on the origin of consumed goods: imported, domestic, or home-produced. Using a unique dataset on household consumption across goods and origins, we estimate the impact of trade liberalization on consumer welfare across income levels in Cambodia. Lower tariffs reduce the cost of living directly through cheaper imported final goods and indirectly via lower costs of imported intermediate inputs used in domestic and home-produced goods. Tariff reductions generate a pronounced pro-rich effect, with the cost of living for the top income decile falling approximately four times more than for the bottom decile. The effect is driven by richer households’ higher expenditure share on imported final goods and their greater reliance on domestic goods that use imported inputs more intensively. Ignoring the origin of goods in consumption substantially underestimates the pro-rich effect, and this result may generalize to other low-income countries.
