Whereas noted economists from across the political spectrum have warned that the implementation of Modern Monetary Theory (referred to in this preamble as MMT ) would pose a clear danger to the economy of the United States; Whereas, on March 4, 2019, former Secretary of the Treasury Lawrence H. Summers said that— (1) MMT is fallacious at multiple levels; (2) past a certain point, MMT leads to hyperinflation; and (3) a policy of relying on a central bank to finance government deficits, as advocated by MMT theorists, would likely result in a collapsing exchange rate; Whereas, on February 26, 2019, Jerome Powell, Chair of the Board of Governors of the Federal Reserve System, said: The idea that deficits don’t matter for countries that can borrow in their own currency I think is just wrong ; Whereas, on March 25, 2019, Janet Yellen, former Chair of the Board of Governors of the Federal Reserve System, disagreed with those individuals promoting MMT who suggest that you don’t have to worry about interest-rate payments because the central bank can buy the debt , stating: That’s a very wrong-minded theory because that’s how you get hyper-inflation ; Whereas the March 2019 report entitled How Reliable is Modern Monetary Theory as a Guide to Policy? by Scott Sumner and Patrick Horan of the Mercatus Center at George Mason University found that— (1) MMT— (A) has a flawed model of inflation, which overestimates the importance of economic slack; (B) overestimates the revenue that can be earned from the creation of money; (C) overestimates the potency of fiscal policy, while underestimating the effectiveness of monetary policy; (D) overestimates the ability of fiscal authorities to control inflation; and (E) contains too few safeguards against the risks of excessive public debt; and (2) an MMT agenda of having fiscal authorities manage monetary policy would run the risk of— (A) very high debts; (B) very high inflation; or (C) very high debts and very high inflation, each of which may be very harmful to the broader economy
