How Americans form and dissolve families has changed dramatically since 1950. One of these changes has been an increase in assortative mating, i.e. how likely a person is to marry someone of similar educational background. This column argues that since education is an important determinant of income, these patterns of matching have had an important impact on the economy's distribution of income.

Discussions of international trade often focus on aggregate trade flows, but it is firms that trade, not countries. This column presents evidence from Norwegian export data showing that larger exporters have more customers and greater dispersion in customer size. Moreover, exporters with many customers tend to sell to importers with few suppliers. These stylised facts are captured by a model in which finding a buyer is costly. The model’s prediction that export responses are amplified in destinations with less buyer dispersion is confirmed in the data.
