Striking it Richer: The Evolution of Top Incomes in the United States
Striking it Richer: The Evolution of Top Incomes in the United States (Updated with 2011 estimates). Emmanuel Saez, January 23, 2013
"During the Great Recession, from 2007 to 2009, average real income per family declined dramatically by 17.4%,1 the largest two year drop since the Great Depression. Average real income for the top percentile fell even faster (36.3 percent decline, Table 1), which lead to a decrease in the top percentile income share from 23.5 to 18.1 percent. Average real income for the bottom 99% also fell sharply by 11.6%, also by far the largest two year decline since the Great Depression. This drop of 11.6% more than erases the 6.8% income gain from 2002 to 2007 for the bottom 99%. The sharp fall in top incomes is explained primarily by the collapse of realized capital gains due to the stock-market crash. Aggregate realized capital gains fell from $895 billion in 2007 to $236 billion in 2009. Indeed, including realized capital gains, the top decile income share dropped from 49.7% in 2007 to 46.5% in 2009 while excluding realized capital gains, the top decile income share remained virtually constant from 45.7% in 2007 to 45.5% in 2009."
