The paper discusses some fundamental problems in monetary economics associated with the determination and role of the numeraire. The issues are introduced by formalising a proposal, attributed to Eisler, to remove the zero lower bound on nominal interest rates by unbundling the numeraire and...

This paper provides a critique of standard theories of money, in particular those based on money as a medium of exchange. Money is important because of the relationship between money and credit. The process of judging credit worthiness, in which banks play a central role, involves the collection...

Woodford (2003) describes a popular class of neo-Wicksellian models in which monetary policy is characterized by an interest-rate rule, and the money market and financial institutions are typically not even modeled. Critics contend that these models are incomplete and unsuitable for...

The ongoing digital revolution may lead to a radical departure from the traditional model of monetary exchange. We may see an unbundling of the separate roles of money, creating fiercer competition among specialized currencies. On the other hand, digital currencies associated with large platform...

The paper discusses simple microfoundations for Liquidity Deflation (Calvo 2016, Chapter 2), which gives rise to liquidity trap under perfectly flexible prices/wages. Unlike Keynes (1936), this is a Supply Side Liquidity Trap, SSLT, not resolved by a fall in prices /wages, or massive helicopter...

We formulate a generalization of the traditional medium-of-exchange function of money in contexts where there is imperfect competition in the intermediation of credit, settlement, or payment services used to conduct transactions. We find that the option to settle transactions directly with money...

In the aftermath of the Great Recession, there is a growing consensus, even among central bank officials, concerning the limitations of monetary policy. This paper provides an explanation for the ineffectiveness of monetary policy, and in doing so provides a new framework for thinking about...

The dangers of high capital flow volatility and sudden stops have led economists to promote the use of capital controls as an addition to monetary policy in emerging market economies. This paper studies the benefits of capital controls and monetary policy in an open economy with financial...

We construct a continuous-time, pure currency economy with the following three key features. First, our modelled economy incorporates idiosyncratic uncertainty—households receive infrequent and random opportunities of lumpy consumption—and displays an endogenous, non-degenerate distribution...
