Does weight-loss medication improve women's marriage and employment outcomes?
Core argument: Women who were single when starting GLP-1 treatment raised their probability of being married or cohabiting by 18.3 pp overall and 28.6 pp (s.e. 7.1) at six or more quarters, building gradually as they lost weight.
BMI is flat before women start [GLP-1 treatment] and then falls (Figure 2, Panel A). All groups lose between 1.4 and 2.5 BMI points in the post period. These effects grow to between 2.7 and 4.2 BMI points at 1.5+ years after initiation. The largest magnitude change is in the marriage market. Women who are single when they start (Figure 2, Panel B) increase their probability of being married or living with a partner by 18.3 pp overall and 28.6pp (s.e. 7.1) at six or more quarters, building gradually as they lose weight. Partnered women’s relationships, by contrast, are stable. Their partnership probability barely moves (0.1 points, s.e. 1.8), and there is no excess relationship dissolution (0.0, s.e. 1.7). The marriage-market response is the making of new matches, not the breaking or remaking of old ones. In contrast, single women’s weight loss seems to dramatically affect first impressions of potential partners, leading to a large increase in marriage and cohabitation. This is consistent with prior work on the obesity penalty negatively affecting women in the marriage market. Figure 2, panels C and D show that women not employed at baseline move into work: their employment rate rises 13pp overall and 27pp after six or more quarters, and their weekly hours rise by nearly ten hours at the longer horizon.
