Can Security Design Foster Household Risk‐Taking?

Abstract

ABSTRACT This paper shows that securities with nonlinear payoff designs can foster household risk‐taking. We demonstrate this effect by exploiting the introduction of capital guarantee products in Sweden between 2002 and 2007. Their fast and broad adoption is associated with an increase in expected financial portfolio returns. The effect is especially strong for households with low‐risk appetite ex ante. These empirical facts are consistent with a life‐cycle model in which households have pessimistic beliefs or preferences combining loss aversion and narrow framing. Our results illustrate how security design can mitigate behavioral biases to increase mean household portfolio returns.
