Data and code for: Assortative Matching at the Top of the Distribution: Evidence from the World's Most Exclusive Marriage Market

Using novel data on peerage marriages in Britain, I find that low search costs and marriage-market segregation can generate sorting. Peers courted in the London Season, a matching technology introducing aristocratic bachelors to debutantes. When Queen Victoria went into mourning for her husband, the Season was interrupted (1861-63), raising search costs, and reducing market segregation. I exploit exogenous variation in women's probability to marry during the interruption from their age in 1861. The interruption increased peer-commoner intermarriage by 40% and reduced sorting along landed wealth by 30%. Eventually, this reduced peers' political power and affected public policy in late-19C England.
