Modern Monetary Theory has received unprecedented attention now that policymakers are pursuing extraordinary economic policy measures to combat the COVID-19 pandemic.

Discussing the U.S. Federal Reserve¡¯s ¡°whatever it takes approach,¡± CNBC¡¯s Joe Kernen recently concluded that ¡°we are all MMTers now.¡± And in a recent commentary, Willem H. Buiter of Columbia University claimed that ¡°much of the U.S. response (to the pandemic) will come in the form of ¡®helicopter money,¡¯ an application of (MMT) in which the central bank finances fiscal stimulus by purchasing government debt issued to finance tax cuts or public spending increases.¡±

As these remarks show, many commentators seem to view MMT as merely a blueprint for turning on the printing press, whether to send cash to Americans through an appropriation by Congress, or to provide liquidity to financial markets through the Fed¡¯s actions. With the recent adoption in the United States of a $2.1 trillion rescue package, we are supposedly now engaged in what Buiter calls ¡°a massive experiment with hitherto unorthodox¡± MMT.
