Democratic Inequality

CHICAGO – Why did the household savings rate in the United States plummet before the Great Recession? Two of my colleagues at the University of Chicago, Marianne Bertrand and Adair Morse, offer an intriguing answer: growing income inequality.

Bertrand and Morse find that in the years before the crisis, in areas (usually states) where consumption was high among households in the top fifth of the income distribution, household consumption was high at lower income levels as well. After ruling out a number of possible explanations, they concluded that poorer households imitated the consumption patterns of richer households in their area.
