Incomes rose more than 11 percent for the top 1 percent of earners during the economic recovery, but not at all for everybody else. The numbers, produced by Emmanuel Saez, an economist at the University of California, Berkeley, show overall income growing by just 1.7 percent over the period. But there was a wide gap between the top 1 percent, whose earnings rose by 11.2 percent, and the other 99 percent, whose earnings declined by 0.4 percent. Mr. Saez, a winner of the John Bates Clark Medal, an economic laurel considered second only to the Nobel, concluded that the Great Recession has only depressed top income shares temporarily and will not undo any of the dramatic increase in top income shares that has taken place since the 1970s." Excluding earnings from investment gains, the top 10 percent of earners took 46.5 percent of all income in 2011, the highest proportion since 1917, Mr. Saez said, citing a large body of work on earnings distribution over the last century that he has produced with the economist Thomas Piketty of the Paris School of Economics.
