Limited Stock Market Participation Among Renters and Homeowners
研究发现房主的股市参与率是租房者的两倍，通过构建生命周期模型和面板数据分析，表明偏好异质性而非住房的挤出效应是主要原因。
Abstract The stock market participation rate among homeowners is twice as high as among renters. This paper builds a life-cycle portfolio choice model with endogenous housing tenure choice. A stylized form of preference heterogeneity generates a substantial difference in participation rates. A majority of households have a large savings motive and choose to be homeowners and participate. A minority of households have a small savings motive and find it less worthwhile to participate. Fewer of these households become homeowners. Difference-in-difference regressions on panel data do not find evidence of a crowding-out effect of homeownership on participation, supporting the message that preference heterogeneity matters.
