摘要：
Selection markets create a multitasking environment where intermediary agents often need to increase consumer take-up as well as resolve information asymmetries about consumer expected cost during the sales process. I study how artificial intelligence (AI) affects attention allocation and information production in human-intermediated markets by analyzing a large-scale randomized experiment conducted by a top insurance agency in China. In the experiment, the firm provided treated agents with an AI-generated estimation of consumer demand for insurance, based on consumer digital footprints on the advertisements on social media; these footprints were available to all agents prior to the experiment. I show that AI demand prediction shifts agents' attention to converting high-intent consumers, improving agents' sales by 14%. As an unintended consequence, AI-generated demand information reduces agents' own information acquisition and increases adverse selection, consistent with attention models and a crowding out of risk information. Moreover, treated agents bring in riskier consumers but do not match them to more expensive products to achieve stronger incentive compatibility. The findings suggest that a common application of AI to predict consumer demand can have side effects on human information production, market efficiency, and can exacerbate agency conflicts when intermediary agents capitalize on AI.

主讲人简介：
Matthew Neidell is a professor of economics at Columbia University in the Department of Health Policy and Management. Professor Neidell specializes in environmental, health, and labor economics. His most recent work applies the latest empirical methods to examine the relationship between the environment and a wide range of measures of well-being, including worker productivity, human capital, and decision making. Previous related work has focused on the effect of the environment on health outcomes and avoidance behavior.
摘要：
This study explores how temperature-induced hospital crowding influences care trajectories and patient outcomes. Utilizing comprehensive data from Mexico’s largest healthcare subsystem from 2012 to 2019, including emergency, inpatient, and outpatient visits, we delve into the impact of daily temperature shocks on healthcare service dynamics. Our findings reveal a linear increase in healthcare demand reaching a 10% uptick in emergency department visits in the hottest bin compared to average days. While more patients are admitted from ERs into hospitals, the likelihood of an individual patient's admission decreases as temperatures climb, suggesting a capacity crunch in healthcare facilities. This trend of increasing patient triage leads to more severe patients being sent home on hotter days. Furthermore, we observe a deterioration in care quality, reflected in heightened excess mortality rates inside hospitals. Data from death certificates confirm an overall increase in mortality on extreme days. Deaths outside hospitals, in particular, escalate more sharply. Our results shed light on the broader implications of climate-driven hospital crowding.
