What supply-side economics is and isn’t. From Paul Craig Roberts at paulcraigroberts.com:
For a decade central banks have printed enormous quantities of new money. The excuse is to stimulate the economy by reviving inflation. However, the money has, for the most part, driven up the prices of financial assets instead of consumer and producer prices. The result has been a massive increase in the inequality of income, wealth, and opportunity.
The quantitative easing policy followed by central banks is based on belief in an economic relationship between inflation and GDP growth—the Phillips curve—that supply-side economics disproved during the Reagan administration. The belief in the Phillips curve persists, because supply-side economics was misrepresented by the financial media and neoliberal junk economics.
The fact that something as straightforward and well explained as supply-side economics can be misrepresented for 35 years should give us all pause. When successive chairmen of the Federal Reserve and other central banks have no correct idea what supply-side economics is, how can they formulate a workable monetary policy? They cannot.
The Phillips Curve is the modern day version of the Unicorn. People believe in it, but no one can find it. The Fed has been searching for it for a decade and the Bank of Japan for two decades. So has Wall Street.
Central banks’ excuse for their massive injections of liquidity in the 21st century is that they are striving to stimulate the 2% rate of inflation that they think is the requirement for sustained rises in wages and GDP. In a total contradiction of the Phillips Curve, in Japan massive doses of central bank liquidity have resulted in the collapse of both consumer and financial asset prices. In the US the result has been a large increase in stock averages propelled by unrealistic P/E ratios and financial speculation resulting in Tesla’s capitalization at times exceeding that of General Motors.
In effect pursuit of the Phillips Curve has become a policy of ensuring financial stability of over-sized banks by continually injecting massive amounts of liquidity. The result is greater financial instability. The Fed is now confronted with a stock market disconnected from corporate profits and consumer disposable income, and with insurance companies and pension funds that have been unable for a decade to balance equity portfolios with interest bearing debt instruments. Crisis is everywhere in the air. What to do?
