James Pennington's creativity as a scientific economist is matched only by his obscurity. He exemplifies the pioneering innovator who never gets his due recognition. Alone and with others he launched (1) the idea that checking deposits are money just like coin and notes, (2) the theory of the...

These notes contain the derivations for results stated without proof in Hornstein (2007). First, I derive the log-linear approximation of the inflation dynamics in the Calvo-model with elements of backward-looking pricing when the approximation takes place around a positive average inflation...

Marshall made at least four contributions to the classical quantity theory. He endowed it with his Cambridge cash-balance money-supply-and-demand framework to explain how the nominal money supply relative to real money demand determines the price level. He combined it with the assumption of...

Many different models of money stock determination exist in the literature. An attempt is made here to understand why the differences in these models arise. Differences in models are ascribed first to the (usually implicit) role assigned to the price level. From this perspective, models fall...

This paper provides a detailed examination of various money stock control procedures in a rational expectations environment. The analysis investigates the relative efficiency of controlling monetary aggregate through the use of an interest rate instrument or through various reserve measures...

In any discussion of the demand for money it is important to be clear about the concept of money that is being utilized; otherwise, misunderstandings can arise because of the various possible meanings that readers could have in mind. Here the term will be taken to refer to an economy's medium of...

The 1920s and 1930s saw the Fed reject a state-of-the-art empirical policy framework for a logically defective one. Consisting of a quantity theoretic analysis of the business cycle, the former framework featured the money stock, price level, and real interest rates as policy indicators. By...

What is the source of interest rate volatility? Why do low interest rates precede business cycle booms? Most observers tend to assume that monetary policy is largely responsible for it. Indeed, a standard real business cycle model delivers rather small fluctuations in real interest rates. Here,...

Thirty years ago it appeared that the best strategy for improving economic forecasts was to build bigger, more detailed models. As the costs of computing plummeted, considerable detail was added to models and more elaborate statistical techniques became feasible.
