This paper argues that distributions of spousal earnings gaps provide no identifying information for the male breadwinner norm, nor such a norm's consequences for gender inequality. First, we show that simple marital matching models-without norm-related assumptions-closely replicate U.S. distributions of wife-husband earnings gaps. Second, we show that the discontinuity in this distribution as wives start to out-earn husbands reflects not breadwinner norms, but rather a point mass of equal-earning couples. We conclude by arguing that the point mass may also threaten other tests of the male breadwinner hypothesis, and proposing several robustness checks that future research should utilize.
