Rehypothecation refers to the practice of re-using (selling or pledging as collateral) an asset that has already been pledged as collateral for a loan. We develop a dynamic general equilibrium monetary model where an “asset shortage” motivates the rehypothecation of assets. We find that in...

We construct a model in which all consolidated government debt is used in transactions, with money being more widely acceptable. When asset market constraints bind, the model can deliver low real interest rates and positive rates of inflation at the zero lower bound. Optimal monetary policy in...

This paper studies the optimal maturity structure for government debt when markets for liquidity insurance are incomplete or non-competitive. There is no fiscal risk. Government debt in the model solves a dynamic inefficiency. Issuing debt in short and long maturities solves a liquidity...

I investigate the theoretical impact of central bank digital currency (CBDC) on a monopolistic banking sector. The framework combines the Diamond (1965) model of government debt with the Klein (1971) and Monti (1972) model of banking. There are two main results. First, the introduction of...

A wide range of heterodox theories claim that banks are special because they create money in the act of lending. Put another way, banks can create the funding they need ex nihilo, whereas all other agencies must first acquire the funding they need from other parties. Mainstream economic theory...

We study the effects of money (anticipated inflation) on capital formation. Previous papers on this adopt reduced-form approaches, putting money in the utility function or imposing cash in advance, but use otherwise frictionless models. We follow a literature that is more explicit about the...

The author studies a simple dynamic general equilibrium monetary model to interpret key macroeconomic developments in the U.S. economy both before and after the Great Recession. In normal times, when the Federal Reserve’s policy rate is above the interest paid on reserves, countercyclical...
