The Burden Of Adjustment And Keynes’ Solution

Argentina had a balance-of-payments crisis recently and required help. The IMF has agreed for a stand-by arrangement of $50 billion on the condition in the IMF’s own words:

“At the core of the government’s economic plan is a rebalancing of the fiscal position. We fully support this priority and welcome the authorities’ intention to accelerate the pace at which they reduce the federal government’s deficit, restoring the primary balance by 2020. This measure will ultimately lessen the government financing needs, put public debt on a downward trajectory, and as President Macri has stated, relieve a burden from Argentina’s back.

So Argentina has to agree on policies with deflationary bias to its output. John Maynard Keynes made this observation, had a completely different attitude than the IMF and proposed to change it. From The Collected Writings Of John Maynard Keynes, Volume XXV: Shaping The Post-War World: The Clearing Union, Chapter 1, The Origins Of The Clearing Union, 1940-1942, pages 27-30:

III. The Analysis of the Problem

I believe that the main cause of failure (except in special, transient conditions) of the freely convertible international metallic standard (first silver and then gold) can be traced to a single characteristic. I ask close attention to this, because I should argue that this provides the clue to the nature of any alternative which is to be successful.

It is characteristic of a freely convertible international standard that it throws the main burden of adjustment on the country which is in the debtor position on the international balance of payments,—that is on the country which is (in this context) by hypothesis the weaker and above all the smaller in comparison with the other side of the scales which (for this purpose) is the rest of the world.

Take the classical theory that the unlimited free flow of gold automatically brings about adjustments of price-levels and activity between the debtor country and the recipient creditor, which will eventually reverse the pressure. It is usual to-day to object to this theory that it is too dependent on a crude and now abandoned quantity theory of money and that it ignores the lack of elasticity in the social structure of wages and prices. But even to the extent that it holds good in spite of these grave objections, if a country is in economic importance even a fifth of the world as a whole, a given loss of gold will presumably exercise four times as much pressure at home as abroad, with a still greater disparity if it is only a tenth or a twentieth of the world, so that the contribution in terms of the resulting social strains which the debtor country has to make to the restoration of equilibrium by changing its prices and wages is altogether out of proportion to the contribution asked of its creditors. Nor is this all. To begin with, the social strain of an adjustment downwards is much greater than that of an adjustment upwards. And besides this, the process of adjustment is compulsory for the debtor and voluntary for the creditor. If the creditor does not choose to make, or allow, his share of the adjustment, he suffers no inconvenience. For whilst a country’s reserve cannot fall below zero, there is no ceiling which sets an upper limit. The same is true if international loans are to be the means of adjustment. The debtor must borrow; the creditor is under no such compulsion.

…

… Thus it has been an inherent characteristic of the automatic international metallic currency (apart from special circumstances) to force adjustments in the direction most disruptive of social order, and to throw the burden on the countries least able to support it, making the poor poorer.

…

I conclude, therefore, that the architects of a successful international system must be guided by these lessons. The object of the new system must be to require the chief initiative from the creditor countries, whilst maintaining enough discipline in the debtor countries to prevent them from exploiting the new ease allowed them in living profligately beyond their means.

So Keynes proposed to change this so that creditors also share the burden. In his plan for Bretton Woods (page 80), he proposed to impose a penalty on creditor nations and also require them to take measures such as:

(a) Measures for the expansion of domestic credit and domestic demand.
(b) The appreciation of its local currency in terms of bancor, or, alternatively, the encouragement of an increase in money rates of earnings;
(c) The reduction of tariffs and other discouragements against imports.
(d) International development loans.

Of course we are past the Bretton Woods system and have a system of a mix of fixed and floating exchange rates but it hasn’t provided the market mechanism required to resolve imbalances. The adjustment is still on output and employment. Hence the need for an official mechanism to resolve imbalances. Bancor isn’t relevant now, but official intervention is.

Preface To The French Edition Of The General Theory

The French edition of Keynes’ The General Theory, has a nice preface explaining what his book is all about. It is dated 20 February 1939.

This is available in The Collected Writings Of John Maynard Keynes, Volume VII – The General Theory Of Employment, Interest And Money. The Collected Writings has volumes I-XXX.

First, Keynes announces how he is breaking from orthodoxy:

For a hundred years or longer English Political Economy has been dominated by an orthodoxy. That is not to say that an unchanging doctrine has prevailed. On the contrary. There has been a progressive evolution of the doctrine. But its presuppositions, its atmosphere, its method have remained surprisingly the same, and a remarkable continuity has been observable through all the changes. In that orthodoxy, in that continuous transition, I was brought up. I learnt it, I taught it, I wrote it. To those looking from outside I probably still belong to it. Subsequent historians of doctrine will regard this book as in essentially the same tradition. But I myself in writing it, and in other recent work which has led up to it, have felt myself to be breaking away from this orthodoxy, to be in strong reaction against it, to be escaping from something, to be gaining an emancipation.

Then Keynes says what he is doing:

I have called my theory a general theory. I mean by this that I am chiefly concerned with the behaviour of the economic system as a whole,—with aggregate incomes, aggregate profits, aggregate output, aggregate employment, aggregate investment, aggregate saving rather than with the incomes, profits, output, employment, investment and saving of particular industries, firms or individuals. And I argue that important mistakes have been made through extending to the system as a whole conclusions which have been correctly arrived at in respect of a part of it taken in isolation.

Keynes, I imagine thought that the root of all orthodoxy is the saving-investment identity. Once this is understood, things follow more easily. He says:

Let me give examples of what I mean. My contention that for the system as a whole the amount of income which is saved, in the sense that it is not spent on current consumption, is and must necessarily be exactly equal to the amount of net new investment has been considered a paradox and has been the occasion of widespread controversy. The explanation of this is undoubtedly to be found in the fact that this relationship of equality between saving and investment, which necessarily holds good for the system as a whole, does not hold good at all for a particular individual. There is no reason whatever why the new investment for which I am responsible should bear any relation whatever to the amount of my own savings. Quite legitimately we regard an individual’s income as independent of what he himself consumes and invests. But this, I have to point out, should not have led us to overlook the fact that the demand arising out of the consumption and investment of one individual is the source of the incomes of other individuals, so that incomes in general are not independent, quite the contrary, of the disposition of individuals to spend and invest; and since in turn the readiness of individuals to spend and invest depends on their incomes, a relationship is set up between aggregate savings and aggregate investment which can be very easily shown, beyond any possibility of reasonable dispute, to be one of exact and necessary equality.

He then says how output is determined not by the capacity to produce but dynamic demand-led processes:

Rightly regarded this is a banale conclusion. But it sets in motion a train of thought from which more substantial matters follow. It is shown that, generally speaking, the actual level of output and employment depends, not on the capacity to produce or on the pre-existing level of incomes, but on the current decisions to produce which depend in turn on current decisions to invest and on present expectations of current and prospective consumption. Moreover, as soon as we know the propensity to consume and to save (as I call it), that is to say the result for the community as a whole of the individual psychological inclinations as to how to dispose of given incomes, we can calculate what level of incomes, and therefore what level of output and employment, is in profit-equilibrium with a given level of new investment; out of which develops the doctrine of the Multiplier.

and introducing the paradox of thrift:

Or again, it becomes evident that an increased propensity to save will ceteris paribus contract incomes and output; whilst an increased inducement to invest will expand them. We are thus able to analyse the factors which determine the income and output of the system as a whole;—we have, in the most exact sense, a theory of employment. Conclusions emerge from this reasoning which are particularly relevant to the problems of public finance and public policy generally and of the trade cycle.

Keynes then argues against the typical claim that the rate of interest adjusts to bring saving equal to investment:

Another feature, specially characteristic of this book, is the theory of the rate of interest. In recent times it has been held by many economists that the rate of current saving determined the supply of free capital, that the rate of current investment governed the demand for it, and that the rate of interest was, so to speak, the equilibrating price-factor determined by the point of intersection of the supply curve of savings and the demand curve of investment. But if aggregate saving is necessarily and in all circumstances exactly equal to aggregate investment, it is evident that this explanation collapses. We have to search elsewhere for the solution. I find it in the idea that it is the function of the rate of interest to preserve equilibrium, not between the demand and the supply of new capital goods, but between the demand and the supply of money, that is to say between the demand for liquidity and the means of satisfying this demand.

Keynes then announces his break away from Monetarism:

I have called this book the General Theory of Employment, Interest and Money; and the third feature to which I may call attention is the treatment of money and prices. The following analysis registers my final escape from the confusions of the Quantity Theory, which once entangled me. I regard the price level as a whole as being determined in precisely the same way as individual prices; that is to say, under the influence of supply and demand. Technical conditions, the level of wages, the extent of unused capacity of plant and labour, and the state of markets and competition determine the supply conditions of individual products and of products as a whole. The decisions of entrepreneurs, which provide the incomes of individual producers and the decisions of those individuals as to the disposition of such incomes determine the conditions. And prices—both individual prices and the price-level— emerge as the resultant of these two factors. Money, and the quantity of money, are not direct influences at this stage of the proceedings. They have done their work at an earlier stage of the analysis. The quantity of money determines the supply of liquid resources, and hence the rate of interest, and in conjunction with other factors (particularly that of confidence) the inducement to invest, which in turn fixes the equilibrium level of incomes, output and employment and (at each stage in conjunction with other factors) the price-level as a whole through the influences of supply and demand thus established.

And finally attacks the docrine of Say’s Law:

I believe that economics everywhere up to recent times has been dominated, much more than has been understood, by the doctrines associated with the name of J.-B. Say. It is true that his ‘law of markets’ has been long abandoned by most economists; but they have not extricated themselves from his basic assumptions and particularly from his fallacy that demand is created by supply. Say was implicitly assuming that the economic system was always operating up to its full capacity, so that a new activity was always in substitution for, and never in addition to, some other activity. Nearly all subsequent economic theory has depended on, in the sense that it has required, this same assumption. Yet a theory so based is clearly incompetent to tackle the problems of unemployment and of the trade cycle. Perhaps I can best express to French readers what I claim for this book by saying that in the theory of production it is a final break-away from the doctrines of J.-B. Say and that in the theory of interest it is a return to the doctrines of Montesquieu.

If you have read Monetary Economics by Wynne Godley and Marc Lavoie, you will notice that their approach is quite close to this spirit. In their approach, the components of demand which are exogenous are government expenditure and exports. Etc.

Christine Lagarde On Germany’s Balance Of Payments

Posted on by

Yesterday, there was a joint conference, Germany – Current Economic Policy Debates, jointly organized by the German Bundesbank and the IMF.

Christine Lagarde wrote an article, Three German Economic Challenges with European Effect at IMFBlog.

In that discusses Germany’s 🇩🇪 current account balance of payments:

Challenge 3: More balanced savings and investments

Another feature of the German economic recovery is the country’s high current account surplus. At nearly 8 percent of GDP, it is also the highest in the world in dollar terms. The high surplus shows that German households and companies still prefer to save rather than invest.

For our part, the IMF has indicated that this surplus is too large—even considering the need to save for retirement in an aging society. Boosting investment in the German economy and reducing the need to save for retirement by encouraging older workers to remain in the labor force can lower the surplus. We need to ask why German households and companies save so much and invest so little, and what policies can resolve this tension.

It’s welcome but still far from any action.

I also have a dislike for this kind of narrative. Usually the phrase saving is used in such discussion because of the identity:

National Saving = National Investment + CAB

where, CAB is the current account balance.

But the saving here is not the same as household saving and/or firms’ saving. Also it needn’t be the case that firms’ investment is low. It’s very well possible that households’ and firms may be saving low and yet the current account balance is high. This is because it depends on other things such as fiscal policy, competitiveness of German firms etc. The same argument is repeated in the other direction when the discussion is about the United States, with the claim that households save too little. But if US households start saving more, the US current account deficit will fall but that will be because of a fall in output and employment.

It’s important to remember that John Maynard Keynes recognized that active policy measures are needed to resolve global imbalances. He proposed to impose penalties on creditor nations in his plan for Bretton-Woods and also require them to take measures such as:

(a) Measures for the expansion of domestic credit and domestic demand.
(b) The appreciation of its local currency in terms of bancor, or, alternatively, the encouragement of an increase in money rates of earnings;
(c) The reduction of tariffs and other discouragements against imports.
(d) International development loans.

– page 24 of The Keynes Plan

Of course Bancor is not the solution but we can still learn from Keynes’ idea for creating policies for balance of payments targets, instead of relying on the market mechanism to resolve imbalances.

John Maynard Keynes On Surplus Nations’ Obligations

Recently, The Economist‘s cover story declared that the government of Germany ought to expand domestic demand and its refusal to do so is a threat to the world economy. It also said, “Germany’s surpluses are themselves a threat to free trade’s legitimacy.”

Post-Keynesians have long recognized this problem with the world economy. Keynes himself said in 1941:

It is characteristic of a freely convertible international standard that it throws the main burden of adjustment on the country which is in the debtor position on the international balance of payments. … The contribution in terms of the resulting social strains which the debtor country has to make to the restoration of equilibrium by changing its prices and wages is altogether out of proportion to the contribution asked of its creditors. Nor is this all. … The social strain of an adjustment downwards is much greater than that of an adjustment upwards. … The process of adjustment is compulsory for the debtor and voluntary for the creditor. If the creditor does not choose to make, or allow, his share of the adjustment, he suffers no inconvenience. For whilst a country’s reserve cannotfall below zero, there is no ceiling which sets an upper limit. The same is true if international loans are to be the means of adjustment. The debtor must borrow; the creditor is under no such compulsion

– in Collected Works, Vol. XXV, pages 27-28.

Few things:

Keynes is building a narrative to argue that creditor nations have responsibilities, although at that time (and also at present), they have no obligation. This was the motivation for his plan for Bretton-Woods, where he proposed to impose fines on creditor/surplus nations and set out some responsibilities for them.

Also, although the above was written keeping in mind a new world order (at 1941), it’s still valid for the post-Bretton-Woods era. This is because, although floating exchange rates help making adjustments, their power is completely exaggerated.

It’s also important to keep in mind, that the world is more complicated now. Creditor/suprlus nations have achieved their status by making adjustments, i.e., by keeping wages and domestic demand low. So it’s not exactly or literally like what Keynes presented. It’s not the best of worlds in Germany or China.

Still, what Keynes said was highly insightful.

It’s also interesting that for The Economist, Germany’s behaviour is a “threat to free trade’s legitimacy.” Nicholas Kaldor also said the same in 1980:

In the absence of … measures all countries may suffer a slower rate of growth and a lower level of output and employment, and not only the group of countries whose economic activity is ‘balance-of-payments constrained’. This is because the ‘surplus’ countries’ own exports will be lower with the shrinkage of world trade, and they may not offset this (or not adequately) by domestic reflationary measures so that their imports will also be lower.

– in Foundations And Implications Of Free Trade Theory

For The Economist, Germany’s behaviour is a threat to free trade. For Post-Keynesians, Germany’s behaviour is expected (and ought to be different) and is a good reason to reject free trade.

But it’s not a bad thing that The Economist recognizes Keynes’ insights.

The Economist On Germany’s Balance Of Payments

The Economist‘s latest cover is about the German balance of payments. The subheading of its editorial says, that it “[t]he country saves too much and spends too little”.

That’s welcome, although the article claims that the German government’s policy is not mercantilist, while at the same time saying that wages have been held down to achieve more competitiveness in exports.

🤦🏻‍♂️

Anyway, it’s good that it has recognized that this is a problem for the world economy. Funnily, the editorial is still defending free trade, without realizing that the ideology is based on the assumption that market forces will resolve imbalances. If the magic of the price mechanism works, why do you need active policy?

It’s important to remember that John Maynard Keynes recognized that active policy measures are needed to resolve global imbalances. He proposed to impose a penalty on creditor nations in his plan for Bretton-Woods and also require them to take measures such as:

(a) Measures for the expansion of domestic credit and domestic demand.
(b) The appreciation of its local currency in terms of bancor, or, alternatively, the encouragement of an increase in money rates of earnings;
(c) The reduction of tariffs and other discouragements against imports.
(d) International development loans.

– page 24 of The Keynes Plan

A lot of times, people argue that the moral stand that Germany reduce its surpluses is vacuous. Germany is independent and responsible for its own decision. Who are others asking German politicians to raise domestic demand?

The answer to that is Germany makes huge gains out of its success in international trade. What if deficit nations form a union and impose high tariffs and quotas on their imports? International trade runs under a set of rules (the “rules of the game”) and other nations have a right to demand this from Germany and ask for fairer rules.

Anyway, The Economist has finally accepted what Keynes was saying 80 years ago!

Two Hundred Years Of Ricardian Trade Theory

Posted on by

Ingrid Kvangraven has a nice article, 200 Years of Ricardian Trade Theory: How Is This Still A Thing? on the blog, Developing Economics. In that, she asks how “the observation of persistent imbalances (and recurring debt crises in the deficit countries) appears to have little impact on the popularity of Ricardo’s theory.”

It’s a nice article going into details about the assumptions of the trade theory, but let me just add another perspective. New Consensus Economics is based on the assumption about the magic of prices and market forces acting to resolve imbalances. Government “intervention” (a loaded word), supposedly spoils this magic and economists are trained to think that this is the reason for crisis. So a New Consensus economist doesn’t find this to be contradictory. “Hey government, why did you interfere with the workings of the market”, an economist is likely to say.

The role of the government in this model is mainly about law and order and is supposed to balance its books. Whenever a crisis arises, economists tend to blame “fiscal profligacy” and recommend contraction of fiscal policy and “economic reforms”.

Of course, since the financial crisis started about ten years back, economists have conceded that they have been wrong about several things. Fiscal policy is one major area where this is so. But the “learned intuition” is so deeply ingrained and ramified into every corner of their minds—borrowing words from Keynes—that it is difficult for them to escape old ideas.

It’s unfortunate that Keynes didn’t stress much about this problem, which is huge. In his GT, he did have a chapter on mercantilism and discussed how the mercantilists behaved the way they behaved because of their distrust in the role of market forces in resolving imbalances. Keynes also had a plan called the Keynes Plan, before the Bretton Woods established. Keynes proposes a fine on creditor nations as well (page 23-24):

from page 23 of IMF’s document on Keynes’ Plan

Usually one only hears of this in Post-Keynesian literature but this was not all. He also proposed other responsibilities for creditors:

from page 24 of IMF’s document on Keynes’ Plan

Of course, the idea of a Bancor sounds crazy because of its similarity to the Euro. The trouble with the Euro is that there is no central government with large fiscal powers, such as in a federation like the United States. Bancor would need a world government. Nonetheless, we can still embrace Keynes’ genius that creditors should take responsibility in the rules of the game and reject Bancor. So apart from the principle of effective demand, this is one of Keynes’ biggest contribution to the history of humankind—that creditor nations have a responsibility.

Unfortunately, the world is still stuck with Ricardo’s ideas!

Robots, Globalization, Unemployment, Etc

Worker: I am losing my job because of globalization.

Economist: No, you are losing it because of automation.

[Plus calling them ‘losers’, such as by saying, “losers of globalization should be compensated”]

This is not just unhelpful but wrong too! Actually, saying it is wrong is underplaying it. It’s okay to be wrong sometimes—everyone is wrong sometimes—but how bad can getting it precisely the opposite every time? Anyone throwing darts at the dartboard can hit the bulls eye by fluke but what is it like throwing darts in the opposite direction?

Economists should be more modest and remind themselves of what Keynes said about workers in The General Theory:

… workers, though unconsciously, are instinctively more reasonable economists than the classical school

There is some irony to all this. Economists have played down the notion of technological unemployment. If production is constant and productivity rises, there’s a fall in employment because less labour is required to produce the same output. So output has to rise to keep employment from falling because of “automation”. In Post-Keynesian economics, the principle of effective demand matters both in the short run and the long run. So technological unemployment is a real possibility. New Consensus economists concede that John Maynard Keynes rules in the short run but assume that Jean-Baptiste Say rules in the long run. The irony hence is that New Consensus economists seem to show worry about automation these days.

In my opinion, this is because the sacred tenet of free trade must be defended by economists at all costs. So they make a concession about loss of employment to robots. Unfortunately that’s not right either. Globalization—both because of competition by international producers and offshoring of jobs via global supply chains—has led to the loss of livelihood for many in the Western world.

Political parties with fascistic tendencies have noticed this huge error at the heart of the New Consensus economics and the liberal political parties to whom these economists advise. They have understood that by pointing out that globalization—under the current rules of the game—can destroy jobs. They have seen support from people. It’s true that the political movement is not likely to deliver much but at the same time, liberal leaning political parties should try to understand this to regain lost ground.

Instead, we see writing such as The Productivity Paradox by Ryan Avent of The Economist. It’s only a paradox if you view it using the lens of the New Consensus Economics. He himself seems to appreciate others’ claims that:

the robot threat is totally overblown: the fantasy, perhaps, of a bubble-mad Silicon Valley — or an effort to distract from workers’ real problems, trade and excessive corporate power.

Not sure why the Silicon Valley gets the blame, and not economists themselves, but anyway, that is some conceding.

Remember the concept of technological unemployment is a race condition.

If productivity rises a lot and demand not much, we have unemployment. If the latter rises fast, we have more employment.

In fact productivity rises in the Western world has been quite low recently and we should embrace robots. This is because measured productivity is likely to rise if output rises. Productivity rise (as per the Kaldor-Verdoon Law) is due to two things: an exogenous component and an endogenous component which depends on the rise in output. Also, remember Keynes talked of autonomous and induced expenditures as component of effective demand, which drives output. So if governments around the world design policy in which demand rises fast, then “automation” can not just be welcomed, it will be a cause of it, i.e., higher production leading to more automation because of learning-by-doing. But economists will continue to get it backward!

“In The Long Run”

But this long run is a misleading guide to current affairs. In the long run we are all dead. Economists set themselves too easy, too useless a task, if in tempestuous seasons they can only tell us, that when the storm is long past, the ocean is flat again.

–  John Maynard Keynes, A Tract on Monetary Reform (1923), Ch. 3, p. 80.

As you might know, the Indian government cancelled the legal tender nature of majority of bank notes in circulation, earlier this month and asked Indians to deposit them at banks or exchange them for new. The aim according to the government was to curb counterfeiting and what’s called black money here. This is damaging as a large amount of transaction is in bank notes and the implementation has been a failure. People have been standing in queues for the whole day and some even reach banks at 2 am to get a good position in the queue. For many, standing in queues means that the day’s labour is lost. For others, there are delays in wage payments since their employers have problems getting hold of new bank notes. More than 50 people have died. Even 11 bank managers have died due to stress and work overload.

Despite this we keep hearing from the government and the ruling political party’s defenders that the benefits will be long term.

The previous Indian Prime Minister (who was the nation’s leader during mid 2004-mid 2014), Manmohan Singh gave a scathing speech in the Indian Parliament yesterday in which he quotes Keynes on the long run. Manmohan Singh was a student at Cambridge and his heroes are Nicholas Kaldor and Joan Robinson and presumably John Maynard Keynes as well. In this era where politicians are promoting neoliberal ideas, it’s good to see the master being quoted in a Parliament.

The seven-minute video is linked below.

click the picture to see the video on YouTube. 

This question about the long-term reminds me of super-hysteresis which was referred by Marc Lavoie recently in an article for INET. It’s closely related to the Kaldor-Verdoorn law in which demand affects supply.  The damage done to the demand side because of slowdown in production caused by the Indian government’s poor implementation of its decision to replace majority of bank notes by value affects the supply side as well. Almost nobody who talks about the long-term benefits talks about this issue.

Free Trade And Balanced Budgets

Wikileaks has released “The Podesta Emails” which show Hillary Rodham Clinton’s political positions best explained by an NYT article:

[Clinton] embraced unfettered international trade and praised a budget-balancing plan that would have required cuts to Social Security, according to documents posted online Friday by WikiLeaks.

The tone and language of the excerpts clash with the fiery liberal approach she used later in her bitter primary battle with Senator Bernie Sanders of Vermont and could have undermined her candidacy had it become public.

Neoliberalism, the “New Consensus” and pre-Keynesian economics stand exactly for this idea: free trade and balanced-budgets. John Maynard Keynes’ true followers starting with Joan Robinson stood exactly in dissent against the idea of free trade and balanced budgets. Keynes himself understood the trouble with free trade, as can be seen by reading his chapter on Mercantilism in the General Theory, but didn’t emphasize it enough. Unlike what others see, Joan Robinson stood for her opposition to free trade more than anything else.

According to the New Consensus of economics, fiscal policy is impotent and hence budget should be balanced. Free trade will lead to convergence of fortunes of nations according to this view. Instead what we see is polarization. In my previous post, I quoted a top advisor who conceded how economists had been wrong about fiscal policy. But the damage seems to have done. Progressive and Keynesian ideas have a long battle ahead.

Needless to say Donald Trump is not the alternative. So there’s a lot of fight ahead for economists in years ahead to overthrow the new consensus. Macroeconomics makes a difference in people’s life, and it’s a battle worth fighting.

On The Blogs

Two things caught my attention in the last two days.

First is the claim by Roger Farmer:

The Keynesian economics of the General Theory is static.

That’s the strangest critique of the GT I have ever seen. How is the GT static? John Maynard Keynes highlighted how a fall in the propensity to consume reduces output. His mechanism was quite dynamic. He was arguing that a fall in the propensity to consume will reduce consumption and hence firms’ sales and hence production and hence employment and hence consumption and so on. Keynes did not explicitly write down a mathematical model like as done for example in the book Monetary Economics by Wynne Godley and Marc Lavoie. But his arguments were quite dynamic in nature. So was his argument about how investment creates saving. And also the Keynesian multiplier. “Stock-flow consistent” models are quite close to Keynes’ spirit.

The second is this paragraph from Michael Pettis:

… This is one of the most fundamental errors that arise from a failure to understand the balance of payments mechanisms. As I explained four years ago in an article for Foreign Policy, “it may be correct to say that the role of the dollar allows Americans to consume beyond their means, but it is just as correct, and probably more so, to say that foreign accumulations of dollars force Americans to consume beyond their means.” As counter-intuitive as it may seem at first, the US does not need foreign capital because the US savings rate is low. The US savings rate is low because it must counterbalance foreign capital inflows, and this is true out of arithmetical necessity, as I showed in a May, 2014 blog entry (link broken: archive.is link).

Oh boy! That’s confusing accounting identities with behaviour. A simple way to show how inaccurate this is by using standard Keynesian analysis. Assume US households reduce the propensity to consume. This leads to a fall in output and income and hence a fall in imports and an increase in the current account balance of payments (assuming exports are exogenous to the model). This can be seen more precisely in a stock-flow consistent model.

Pettis’ arguments are in response to Stephen Roach’s recent article on US balance of payments and I discussed that recently here.  Both Roach and Pettis are incorrect.

Balance of payments is important and in my opinion, the most important thing in Economics. Michael Pettis gets the attention because he realizes the importance of balance of payments in the economic dynamics of the world. However looked more closely, many of his arguments appear vacuous.
