Inequality and InstabilityA Study of the World Economy Just Before
the Great Crisis
ByJames K. GalbraithThe University of Texas at AustinFor the Institute for New Economic ThinkingBerlinApril 14, 2012
“Kepler undertook to draw a curve through the places of Mars, and his greatest service to science was in impressing on men's minds that this was the thing to be done if they wished to improve astronomy; that they were not to content themselves with inquiring whether one system of epicycles was better than another, but that they were to sit down to the figures and find out what the curve, in truth was.”
-- Charles Sanders Peirce (1877)
Inequality as Global Macroeconomics
• At the national level, inequality is in part a curvilinear function of income level – a matter of macroeconomics.
• The Kuznets Curve remains a good starting point, though with modifications for high-income countries.
• Changes in inequality are driven by changing economic structure and economic geography, and changing inter-sectoral terms of trade.
• Global factors dominate movements in global pay inequality.
• Changing financial regimes dominate this picture.

A Stylized “Augmented Kuznets Curve”
This broad picture of the world economy from the standpoint of inequality measure suggests that the “super-bubble” was also, for most of the world’s population, a “super-crisis.”
The super-bubble came to a peak in 2000-20001.
The period since then was marked in the United States by efforts to keep the bubble going, in part through aggressive efforts to relax standards, which may be described as the growth of a “predator state.”
This led to the corruption of the financial markets whose collapse produced the great crisis.
