Karen Petrou: The Inexorable, Inadvertent Inequality Vise
Last week, we sent you an analysis of a new Fed study reinforcing previous research, my own included, finding that U.S. economic inequality exacerbates financial instability. Notably, this paper added an important, novel element: the extent to which economic inequality increases the role of NBFIs and thus heightens systemic risk even more than was the case when banks ran the financial show. But does economic inequality lead to greater NBFI reliance and resulting risk or do NBFIs on their own have a still more pernicious inequality effect that makes the risk of financial crisis still more acute? In short, yes – this is a potent negative-feedback loop of prodigious power.
What makes this feedback loop reverberate so dangerously? More research is essential, but breaking down the income and wealth components of economic inequality into the key drivers of systemic risk along with the regulatory and monetary-policy determinants of financial-sector competitiveness suggests a causal connection between more inequality leading to more NBFIs and more risk leading to more inequality and still more NBFIs and then heightened financial risk and consequential inequality.
In super-short, income inequality is determined in part by wage/salary and capital (i.e., investment) income. The more income from whatever source, the better for buying what one needs and wants unless recessions, progressive taxation, or other personal or policy actions prevent the cumulative increases in income that power up spending and, still more importantly, generate wealth.
Wealth equality is judged by net worth – that is, how much you have …
