What's in a name? Quite a lot it seems

Gregory Clark talks to Viv Davies about his new book titled "The Son Also Rises: Surnames and the History of Social Mobility". Using surname data from eight countries, the study concludes that fate and social status is determined by ancestry and that social mobility rates are lower than conventionally estimated, they do not vary across societies and are resistant to social policies. Effectively, capitalism has not led to pervasive, rapid mobility. The interview was recorded in London in March 2014.
