A consumer economy describes an economy driven by consumer spending as a high percent of its gross domestic product (GDP), as opposed to other major components of GDP (gross private domestic investment, government spending, and imports netted against exports).[1]
In the U.S., it is usually said by economists, including in Henry Hazlitt's "Economics in One Lesson"[2] that 70% of spending is consumer-based,[3][4] but this number is disputed by economists like Businessweek columnist Michael Mandel.[5]
