How does noise in the information cue to the potential spousal quality affect marriage outcomes? We show in a simple two-dimensional matching model, a noisier cue to one feature decreases positive sorting on this feature and does the opposite on other features. While increasing noise reduces overall expected utility, the effect is asymmetric between genders and among people with different features. Our test explores the repeal of the mandatory premarital health examination (PHE) in China – a change making the health cue noisier. We find that this change reduced post-marital subjective well-being, particularly for the females and the healthier. A major channel for the deterioration is the decline in child health, which is associated with the decrease in sorting by health.
