P. Samuelson showed clearly in 1952 that a mathematical economics analysis using abstract symbols can be written out in clear English(or any other language) as well.Samuelson’s assessment of the interchangeability of a correctly translated mathematical analysis into English was clearly...

Nevile writes that : “Thus, it is of considerable interest to speculate on what Keynes would have thought about the way ISLM became identified as "Keynesian" economics for most of the economics profession. We know, of course, what his first reaction to ISLM was in...

Keynes’s IS-LM model in the General Theory, defined in (r,Y) space and contained in chapter 21 in Part IV on pp. 298-299 of the General Theory, was derived from the underlying D-Z model of Chapter 20 that incorporated expectations and uncertainty into the P(expected economic profits-Z) and...

One of the most significant changes in monetary economics in recent years has been the virtual disappearance of what was once a dominant focus on money, and in parallel the disappearance of the LM curve as part of the analytical framework that economists use to think about issues of monetary...

There is already a small literature emphasising the empirical failure of the New Keynesian IS curve, but it is not yet known if this failure reflects empirical problems associated with small samples or is rather a structural weakness of the underlying model. To address this question, in this...

Narrow and broad money measures (including Divisia aggregates) have been found to have explanatory power for UK output in backward-looking specifications of the IS curve. In this paper, we explore whether or not real balances enter into a forward-looking IS curve for the UK, building on the...

This paper considers the implications of the permanent/transitory decomposition of shocks for identification of structural models in the general case where the model might contain more than one permanent structural shock. It provides a simple and intuitive generalization of the influential work...

Changes in both the macroeconomy and in macroeconomics suggest that the IS-LM-AS model is no longer the best baseline model of short-run fluctuations for teaching and policy analysis. This paper presents an alternative model that replaces the assumption that the central bank targets the money...

Keynes spent a tremendous amount of time and energy attempting to tutor Harrod on the mechanics of his IS-LM model between July to September, 1935. Keynes's painstaking slow attempts finally led Keynes in desperation to write a three point postscript to his letter of August, 1935, that is...
