This paper excavates the set of ideas known as modern monetary theory (MMT). The principal conclusion is that the macroeconomics of MMT is a restatement of elementary well-understood Keynesian macroeconomics. There is nothing new in MMT's construction of monetary macroeconomics that warrants the...

This paper begins by defining, and distinguishing between, money and finance, and addresses alternative ways of financing spending. We next examine the role played by financial institutions (e.g., banks) in the provision of finance. The role of government as both regulator of private...

This paper studies optimal monetary and fiscal policies in an economy à la Lucas and Stokey (1983) and Lagos and Wright (2005) with multiple cash and credit goods. We show that optimal policies are in general time inconsistent due to insufficient number of instruments to influence future...

One of the main contributions of Modern Money Theory (MMT) has been to explain why monetarily sovereign governments have a very flexible policy space that is unencumbered by hard financial constraints. Through a detailed analysis of the institutions and practices surrounding the fiscal and...
