Wealth of Nations or Wealth of Persons: World Billionaires and Sector Concentration

Despite the recent global financial crisis, the number of billionaires in USA, Russia, China and Turkey has increased in the last five years, while it has remained at a constant scale in most developed European countries. The aim of the study is to explore whether wealth accumulation is closely related to the sector concentration in billionaire-generating countries. Unlike the previous studies on billionaires, this study examines the relationship between sectors and wealth accumulation of billionaires in some selected billionaire generating countries through secondary data from the Forbes list for the years from 2006 to 2011.
