Does air pollution affect investor cognition and land valuation? Evidence from the Chinese land market
利用中国土地市场日交易数据，发现空气污染显著降低土地竞标价格，尤其对高单价地块和私营开发商影响更大，并通过淮河政策工具变量证实其因果效应。
Abstract This study investigates whether and how air pollution affects investor cognition and valuation in the land market. We find that air pollution significantly affects investor behavior and decreases the bidding prices for land, based on the daily transaction data from the Chinese primary land market. The effect of air pollution on land prices is much stronger for high unit price land parcels and private real estate developers. We exploit the quasi‐natural experiment of Huai River policy as instrument variable and find a causal effect of air pollution on cognitive bias and under valuation in the land market. We further explore the underlying mechanism and find that pollution‐induced change of cognition, mood and behavioral bias play a role. Air pollution‐induced projection bias decreases the demand and bidding price for land. Moreover, air pollution influences investors’ mood and decreases land price premiums.
