Monetarism revisited: in defense of monetarism

It is a privilege to work so close to Tim Congdon particularly since I was appointed Director of the Institute of International monetary Research (IIMR) in January 2016. Tim is the Chairman of the Institute and indeed a leading reference for those who want to understand monetary economics and central banks’ policy decisions; and in particular the role played by changes in the amount of money in circulation on changes in prices (all prices, CPI and asset prices) and nominal income along the business cycle. Changes in the amount of money do lead to portfolio decisions made by households, financial institutions and non-financial companies. The rationale is quite straightforward: in normal times agents tend to keep a rather stable cash to total assets ratio in their portfolios, so the greater the amount of money in the hands of (say) banks and insurance companies, the greater their willingness to invest it in other assets such as real estate, bonds (either long term or short term maturity bonds, or public or private bonds) or equity looking for a greater remuneration. And, should the creation of more and more money continues, it will eventually lead to an increase in the demand of consumption goods and services. Consequently asset prices (and CPI prices, though to a lesser extent) will change as a result of the greater demand for assets in the market and thus higher prices. The new equilibrium in the economy will be reached when agents have got rid of the excess in cash balances in their portfolios so now they keep again their desired cash to asset ratio. As a result of it all the amount of money in the economy will be greater and so will be the price level. M. Friedman and A. Schwartz explained it as clear as marvellously in the 1960s and it remains valid today as a theoretical framework to assess inflation and changes in nominal income.

This is in a nutshell the core of the explanation of monetarism; of course the process by which a greater amount of money in circulation ends up in higher asset and CPI prices can be more complex and, particularly when applied to a policy scenario, it will require a more detailed explanation. Of course there are lags in the transmission of money changes onto prices, as agents take time to assess the market conditions and make their own portfolio adjustments. In addition, institutions matter so a more regulated (less free) economy will require more time to reflect the new monetary conditions on the price level. On top of that the central bank and other financial regulators may interfere further in markets by making new monetary policy decisions, or even changing regulation regarding banks’ capital and/or liquidity ratios. This will make the picture given above more nuanced but by no means invalid; what we know, and there is plenty of evidence about it, is that a sustained increase in the amount of money over the increase in the supply of goods and services in the economy (say the GDP growth) will over time lead to higher prices.

On the 20th of April at the University of Buckingham I had the privilege to discuss with Tim Congdon on (1) what monetarism means nowadays, (2) which are the common criticisms of monetarism and (3) the relevance of monetarism for investment and monetary policy decisions. In fact, in the last few minutes in the video Tim sets up very clearly what it can well be labelled as an operational monetary policy rule for central banks to make policy decisions.

Many will find monetarism a not very fancy or topical term; call it instead rigorous monetary analysis then. As long as we focus on the impact of changes in the amount of money on prices and nominal income I do not think we should pay too much attention to labels. Unfortunately there is virtually a vacuum in this field in our days, as most central banks (not all) and financial regulators have seemed to forget or even disregard the valuable information provided by the analysis of changes in the amount money (and how it is created) for monetary policy purposes.

Enjoy the video with the interview below; comments, as ever, very much welcome.

The Institute of International Monetary Research: it’s all about money!

A new monetary research centre has been established in collaboration with the University of Buckingham early this year, the Institute of International Monetary Research, to study something we should not have ever forgotten, the importance of the analysis of money growth in any modern economy. I know, it sounds simple and even obvious but it happens that we have disregarded monetary analysis for far too long, perhaps under the overall  dominant presumption at the time that just by focusing on stabilising CPI inflation (around a low but still positive rate of growth) the economy could maintain a stable rate of long term growth. As stated on the Institute’s website, its mission is quite clear:

“The purpose of the Institute of International Monetary Research is to demonstrate and bring to public attention the strong relationship between the quantity of money on the one hand, and the levels of national income and expenditure on the other.”

Of course, central banks claim they have always paid attention to monetary aggregates; you may ask, ‘how could a central bank forget about money?!’ Well, let’s start saying that some have indeed forgotten more than others, and even those which did explicitly include a monetary analysis in its reports and in the communication with the public usually gave far more weight to other (macro) indicators in the making of monetary policy decisions, to say the least … . The facts well speak for themselves, and this is what clearly happened, at the very least in the 4-5 years prior to the outbreak of the Global Financial Crisis (GFC). We have seen again booming broad money growth during the last phase of the expansionary years prior to 2008 and then a sudden collapse in the midst of the GFC. The consequences and the impact on output growth have been enormous and this is another reminder on the key importance of keeping a stable rate of growth of money on long term basis as a policy goal. Those familiar with this blog will not find surprising my emphasis on monetary stability (see just a recent post on the topic here; let me say that I myself devoted my PhD dissertation to the distinction between monetary stability and price stability back in 2003! But of course nobody paid much attention to it then …).

Here you will find a video and the slides to the presentation of the Institute in London on the 11th of June (at the Royal Automobile Club), by its Director Tim Congdon. I have had the privilege to contribute to the Institute as one of its Deputy Directors and I do firmly believe there is ample room to both develop ourselves and cooperate with other colleagues and institutions to encourage much more monetary (and monetarist) research in the years to come so we can get a better understanding on the relation between broad money growth, overall inflation, asset price inflation and nominal income. More news and posts on the Institute’s events and agenda will follow.
