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...

We develop and estimate an open economy New Keynesian Phillips curve (NKPC) in which variable demand elasticities give rise to changes in desired markups in response to changes in competitive pressure from abroad. A parametric restriction on our specification yields the standard NKPC, in which...

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...

This paper illustrates that the introduction of a money demand distortion into an otherwise standard New Keynesian Open Economy model generates multiple discretionary equilibria. These equilibria arise in the form of expectations traps whereby the monetary authority is trapped into validating...

This retrospective provides a biographical history of Denis Sargan's career and reviews his contributions to econometrics, emphasizing the breadth of his work in both theoretical and applied econometrics. We include a complete bibliography for Denis and a list of PhD theses that he...

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...

In this paper, we investigate a number of issues that have not been completely addressed in previous studies regarding the possible asymmetric effects of monetary policy. Overall, we interpret our results as weak evidence in favor of sticky-wage and sticky-price theories and strong evidence...

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...
