This document discusses economist Gary Becker's application of economic tools to analyze marriage and the family. It provides statistics on marriage, divorce, and fertility rates in the US and Turkey from 1950 to 2013. Becker identified gains from marriage like increased productivity, health, wealth, and successful children through specialization between spouses and risk-sharing. The document uses production possibility curves to illustrate how productivity differs between individuals and how marriage allows for gains by specializing. It presents a marriage market model where the supply and demand for marriage depends on whether the share of output from marriage is higher for males or females.
