Abstract

Three in four couples in the United States today share party identity. Nearly half of adults aged 25 to 45 are unpartnered. We estimate how much of this sorting and singlehood reflects partisan aversion in partner choice. Observed matches confound preferences with availability. To separate them, we run a discrete choice experiment on approximately 1,000 Democrats and Republicans aged 25 to 45 in which party identity, education, and income vary independently across partner profiles. Randomization identifies willingness to pay for partisan alignment, independent of local market composition. Democrats would give up about $210,000 and Republicans about $120,000 in annual partner income to avoid a typical cross-party partner. We embed these preferences in a transferable-utility matching model calibrated to observed population shares and couple-type distributions. Removing partisan aversion while holding composition fixed substantially reduces singlehood and sharply increases the cross-party couple share, with economically meaningful welfare gains in partner-income equivalents. Equalizing partisan composition while holding preferences fixed has much smaller effects, since a modest gender gap in party shares cannot offset large preference penalties on cross-party matches. Republican men and Democratic women gain most from removing aversion because they face the thinnest same-party pools, while their entry into cross-party matches erodes the gains for previously well-matched types.
