Thomas Schelling, game theorist and co-recipient of the 2005 Nobel Memorial Prize in Economic Sciences, passed away in December 2016 at the age of 95. This column explores how his lack of concern with professional methodological norms allowed him to generate new knowledge with great freedom, and to make innovations in method that may end up being even more significant than his specific insights into economic and social life.

Racial disparities in socioeconomic conditions remain a major policy issue throughout the world. This column applies a new neighbour-based measure of residential segregation to US census data from 1880 and 1940. The authors find that existing measures understate the extent of segregation, and that segregation increased in rural as well as urban areas. The dramatic decline in opposite-race neighbours during the 20th century may help to explain the persistence of racial inequality in the US.
