The fourth Godley-Tobin lecture was by Marc Lavoie on February 2021. The video of the talk is on YouTube.
There is now a paper by the same title published with ROKE (Review Of Keynesian Economics).
It’s interesting how James Tobin had a lot of things right but yet his model has a lot of neoclassical economics.
In the paper Marc Lavoie argues how Tobin seems to get a lot of things right but those were just weapons for criticisms of extreme views such as of Friedman. Tobin didn’t actually believe in them. Wynne Godley’s models are quite successful in escaping old ideas, if you remember the ending line of the preface of the GT.
I was rereading the articleKeynes And The Management Of Real National Income And Expenditure by Wynne Godley from 1983 (page 157 in that book, footnote 20) and he reminds us of this letter from JMK published in The Collected Writings Of John Maynard Keynes, Volume XXVI, pages 287-289, that he thought that import controls work much better than movements in the exchange rates.
To J. M. FLEMING, 13 March 1944
Dear Fleming,
Your paper on quotas versus depreciation, sent me with your letter of February 14th, raises a very interesting question. But, for my own part, I am not one of the’ most economists’, to whom in paragraph 2 you attribute the view that disequilibrium ought, so far as possible, to be corrected by movements in the rate of exchange rather than by controls over commodity trade.
There is, first of all, to the contrary the simple-minded argument that, after all, restriction of imports does do the trick, whereas movements in the rate of exchange do not necessarily do so.
Senate Poised To Pass Huge Industrial Policy Bill To Counter China is the headline of a recent news item from The New York Times.
US politicians have come to realise—especially after the rise of Trump—that free trade and globalisation is a major cause of damage to the US economy. The purpose of industrial policy is to make US producers more competitive. This results in increase of exports and fall in imports, relative to gdp.
Wynne Godley had been warning for quite some time on how the US government should address the trade imbalance instead of leaving it to market forces. In March 2003, in an articleThe U.S. Economy: A Changing Strategic Predicament he said:
The default conclusion is that the U.S. economy will not recover properly in the medium term, but rather will enter a prolonged period of “growth recession.” The only lasting solution will be to get U.S. exports to rise much faster than imports over a prolonged period.
And also suggested non-selected protectionism for the short term.
Another recent news article from NYT is about a global tax coordination. Globalisation has led to a race to the bottom. To raise price competitiveness, countries have been wrongly incentivised to reduce tax rates on firms and this led to some competition between countries to keep reducing tax rates on corporations. And this has led to lot of economic damage.
The Democratic Party of the US has learned from mistakes in the past and is trying to correct them but the Dems are total corporatists and these measures are just for elite preservation. For example, they were talking of reversing Trump’s tax cuts for corporations but the party is a champion in performative politics: it seems they’re not reversing it now.
As Joseph Stiglitz points out, the problem with this 15% tax rate is that it become the de facto the maximum tax rate.
In his last paper, Wynne Godley said on rebalancing:
It is inconceivable that such a large rebalancing could occur without a drastic change in the institutions responsible for running the world economy—a change that would involve placing far less than total reliance on market forces.
Although the steps taken by the US government looks in the right direction, there’s still a large way to go, especially considering how the Democrats pretend to do all sorts of good things. Still far from a Keynes like plan to fine surplus countries and to remove imbalances in balance of payments and international investment position.
There was a conference on the 10th death anniversary of Wynne Godley last year. If you haven’t seen it, the video recordings/presentation/remarks are in that link.
Now, there’s a special issue by the JPKE about the conference with papers as in the cover:
A good macroeconomic model would use national accounts and the flow of funds with behavioural hypotheses. It’s complicated by the fact that prices of goods and services change. It’s not just that if prices of goods and services change, you’re consumption would change in response to that, but also because say the deposits you hold in the bank is worth less.
So your behavioural equations need to be modified. It’s not easy. Wynne Godley recalls in his book Monetary Economics:
And no lesser authority than Richard Stone (1973) made the same mistake because in his definition of real income he did not deduct the erosion, due to inflation, of the real value of household wealth.

The system of national accounts does recognise the importance of this but there aren’t any real variables defined. Real as opposed to nominal. Instead holding gains (formal phrase for “capital gains”) is divided into two parts: real holding gains and neutral holding gains. So,
Assets prices can rise differently than prices of goods and services. Para 12.89 says:
The real holding gain on an asset is defined as the difference between the nominal and the neutral holding gain on that asset. The values of the real holding gains on assets thus depend on the movements of their prices over the period in question, relative to movements of other prices, on average, as measured by the general price index. An increase in the relative price of an asset leads to a positive real holding gain and a decrease in the relative price of an asset leads to a negative real gain, whether the general price level is rising, falling or stationary.
Of course we should consider holding gains and losses on liabilities as well.
This is anyway complicated practically. I haven’t yet seen national accounts of any country producing such tables. But the SNA—including the 2008 SNA—doesn’t have any framework beyond this. This is because it considers that economic behaviour would be different for real holding gains or losses, as opposed to just the flow aspect.
In other words, if your (nominal) income is $100 and there’s a 10% inflation, your consumption would fall. But you might not react the same if you have a real holding loss of $10.
But to a first approximation you could simplify and bring real holding gains into real income. I have simplified quite a bit and these are quite challenging things, so I refer you to Wynne Godley and Marc Lavoie’s (G&L)’s book Monetary Economics.
I wrote this post after an online discussion about the government “inflating away the nominal debt”. Although such claims are loaded, there is some logic to it. In inflation accounting, holding gains/losses appear in incomes. Modeling involves going back and forth between real and nominal variables.
An original writing is that of Wynne Godley (and Ken Coutts and Graham Gudgin)—a 1985 paper titled Inflation Accounting Of Whole Economic Systems. In that you see the equation:
So the government disposable income (in addition to taxes and central bank profits, also has the holding losses due to the fact that prices of goods and services has increased in the period, not just because of changes in prices of government bonds).
Of course, there’s also the loadedness of the phrase “inflating away the debt”. That’s a different matter, my point here is to address the intuition of why inflation can be thought of as bringing revenue to the government and reducing its debt.
James Tobin pioneered the stock-flow consistent modeling. He won the Nobel Prize for it. You can find his Nobel lecture Money And Finance In The Macroeconomic Processhere.
Although quite brilliant, there are many shortcomings in James Tobin’s approach. The genius of Wynne’s approach was to overcome those.
Although the release is more than a month old, I missed the release. The US international investment position is worsening and in unsustainable territory.
Chart from the BEA release dated 29 December, 2020, with last data point from Q3, 2020:
It’s not plotted relative to gdp, but work that out in your head 😉
Wynne Godley’s analysis before 2008 was simple: the US private sector balance—the difference between private expenditure and private income—was negative continuously and was unsustainable. The reversal—private expenditure falling relative to private income—would lead to a large crisis. And meanwhile the US trade was also weak and a large fiscal stimulus would be needed but because of international trade, the fiscal multiplier won’t be large enough and the recovery would be weak. His papers also forecast rising negative net international position mirrored by large rise in public debt relative to gdp, so to keep a sustainable configuration, the US government should directly address international trade, or else face slow growth.
… financial balances (relative to income flows) must stay within certain limits if debts are not to grow excessively, implying that the monitoring of these balances may yield a warning that unsustainable processes are at work.
Also, the “investment income” in balance of payments—the flows—stays positive. A lots has been written on it but on the question of sustainability it’s not too important in my view, although of course, once it turns negative it accelerates the already unsustainable position.
Jan Hatzius of Goldman Sachs talks about how he drew inspiration from Wynne Godley in the latest Odd Lots podcast hosted by Joe Weisenthal and Tracy Alloway of Bloomberg.
He talks of how the private sector financial balance (or net lending) is an important thing to look at to predict crisis.
Wynne Godley in a 1988 article, The Sensibility Of Contemporary Institutions in Theology, (first given as a Sermon before the University in King’s College Chapel, 31 May 1987:
Recourse to the dictionary gives, among the definitions of the word sensibility, ‘the glad or sorrowful recognition of a fact or a condition of things’. Also, ‘readiness to feel compassion for suffering’.
…
But the major issues at stake have been vastly more important than ones which concern sensibility narrowly defined. They go beyond who becomes rich and who remains poor. They extend to matters such as slavery, mass unemployment and civil war.

… The IMF would do well to reperuse its own Article I, which .lists among its purposes: ‘to facilitate the expansion and balanced growth of international trade, and to contribute thereby to the promotion and maintenance of high levels of employment and real income and to the development of the productive resources of all members as primary objectives of economic policy … ‘ In this passage you hear the authentic note of optimism and mutual concern which informed economic relationships within and between countries in the first twenty-five years after the war.
I have been forced to recognize with sadness and very great disappointment that I have so far failed in my personal endeavour to change the course of events or the attitudes of other people. But I remain steadfast to what I understand to be the meaning of Christianity: the unique value it places on the individual inner life; the ability to tolerate aloneness and the imminence of death; the joyful and sensitive concern for and love of other human beings.
