This paper looks at the history of money and its modern form from a scientific and mathematical point of view. The approach here is to emphasize simplicity. A straightforward model and algebraic formula for a large economy analogous to the ideal gas law of thermodynamics is proposed. It may be...

The determinants of money velocity are explored under various assumptions on interest rate uncertainty in a monetary general equilibrium model. It is found that the appearance of velocity function instability can be produced by overlooking interest rate stochastic volatility. In addition, when...

Lucas (1972) is the pathbreaking analysis of the neutrality and temporary non-neutrality of money. But our central banks set interest rate targets, and do not even pretend to control money supplies. How is inflation determined under an interest rate target?

This paper assesses the proximate causes of the post pandemic surge in US inflation, the Federal Reserve's real time reaction to and interpretation of incoming data in 2021, and the pivot to raising rates and shrinking the balance sheet that commenced in 2022 and continues in 2023. Particular...

This paper uses the recent cross-country experience with quantitative tightening (QT) to assess the impact of shrinking central bank balance sheets. We analyze the experience in seven advanced economies (Australia, Canada, Euro area, New Zealand, Sweden, UK and US)--documenting different...

Recent empirical results about the US term structure are difficult to reconcile with the classical hypothesis of rational expectations even if time-varying but stationary term premia are allowed for. A hypothesis of rational learning about the conditional variance of the log pricing kernel is...

We study equilibria in a heterogeneous-agent incomplete-market economy with nominal government debt and flexible prices. Unlike in representative agent economies, steady-state equilibria exist when the government runs persistent deficits, provided that the level of deficits is not too large. In...

We develop a general equilibrium model that highlights the trade-offs between physical and digital forms of retail central bank money. The key differences between cash and central bank digital currency (CBDC) include transaction efficiency, possibilities for tax evasion, and, potentially,...

The world economy has experienced the largest financial crisis in generations, a global pandemic, and a resurgence in inflation during the first quarter of the 21st century, yielding important insights for central banking. Price stability has important benefits and is the responsibility of a...

We document that the convenience yield of U.S. Treasuries exhibits properties that are consistent with a hedging perspective of safe assets. The convenience yield tends to be low when the covariance of Treasury returns with the aggregate stock market returns is high. A decomposition of the...
