A Comparison of Risk Willingness Between Same-Sex and Different-Sex Couples: A Quasi-Experimental Approach

Household composition in the United States is increasingly diverse; however, research into the diversity of the financial decision maker’s sexual orientation has yet to be explored. This analysis examines whether there are differences in financial risk tolerance between same-sex and different-sex couples using data from the Survey of Consumer Finances. The results from a propensity score matching technique, a Mann–Whitney U test, and interpretations of average treatment effects and average treatment effects of the treated suggest there is a statistical difference in risk tolerance between couples and that, on average, same-sex households are significantly more likely to report higher risk tolerance scores, at the 10% alpha level, when compared to their counterparts. Both treatment effect estimates suggest a high impact of the treatment at the 1% alpha level. This highlights the importance of not assuming homogeneous risk preferences across household types. These findings emphasize the importance of recognizing diversity in household composition. Thus, this study identifies the need for inclusiveness in all segments of financial planning.
