The Market Dynamics of Collective Ignorance and Spiraling Risk
研究了市场中产品风险随时间上升的现象，发现消费者并非因风险偏好改变而选择高风险产品，而是市场动态导致集体忽视风险，以匈牙利抵押贷款市场为例提出三阶段模型。
Abstract In some markets, offerings become riskier over time as producers introduce new versions that are made more affordable by increasing their risk. Existing theories suggest consumers adopt riskier versions either because they become more risk tolerant or they trade higher risk for lower price—both of which presume consumers know the risks. We reveal a third explanation: evolving market dynamics that increasingly encourage consumer inattention to risk and produce “collective ignorance.” We identify factors of collective inattention and propose a three-stage model of development of collective ignorance by analyzing the case of risk buildup in the Hungarian mortgage market. Data include archival materials and interviews with borrowers, lenders, and regulators. Initially, producers offer low-risk products, and social, cultural, and institutional factors encourage attention to risk. Consumers attentive to and capable of assessing risk become early adopters. Over time, increasing adoption and changes in market factors divert consumers’ attention from risk, shifting it to price. Under insufficient regulation, risk escalates: producers repeatedly cut price by offering increasingly risky products, while rising collective ignorance leads even risk-averse consumers to adopt them. We offer theoretical contributions to research on the social construction of risk, the attitude–behavior gap, and neoliberal responsibilization.
