Does It Pay to Invest? The Personal Equity Risk Premium and Stock Market Participation

Abstract

Individuals’ stock market participation depends on the risk–return trade-off they expect to achieve from investing. We argue that the expected economic benefits from investing are highly heterogeneous. To capture these benefits, we define the personal equity risk premium (PERP) as the difference between an individual’s expected stock return and personal opportunity cost of capital. We find that the PERP is a significant determinant of stock market participation. Our results hold after we control for known factors, such as financial literacy, trust, and loss aversion. The results are stronger when we analyze the level of stock investment. Disentangling the PERP into its two components shows that both contribute to explain both stock market participation and the level of participation.
