Ronald Coase has died at the age of 102. Many scholars in law, economics, and public policy benefited greatly from Coase’s insights. His 1960 paper “The Problem of Social Costs” is one that I have assigned annually in several of my courses and it has always given rise to some lively discussions. There is a nice overview of Coase’s life at the University of Chicago Law School.
By the way, Coase’s last book, How China Became Capitalist (coauthored with a former graduate student) was published when he was 101 years old.
