The Role of Money: Credible Asset or Numeraire?

Abstract

It is well known that money is neutral if 1) people hold the extraneous belief that it is an only numeraire and does not possess intrinstic value, and 2) new money is injected into an economy as its own interest in the OLG model under perfect information (Lucas [1] Theorem (2)). We find that whenever 1) is not satisfied and money is rationally held to have substance value, money becomes non-neutral even if we use the same model as Lucas [1].
