Class Based Economics

April 16, 2014 2 comments

from Peter Radford

Buried somewhere in the pile of stuff I have accumulated as I think about inequality are these statistics:

  1. Of all the income generated between 2009 and 2011 in the US 121% went to the top 1% of income earners
  2. The top 1% owns just over half of all investment assets including 64.4% of all bonds
  3. And, the bottom 90% incurs 72.5% of all debt

Think through the consequences of these numbers.

Basically we have an economy where the top 1% reaps all the rewards; where less well off people constantly fall further behind; and where the top folk lend to the bottom folk so that the less well off can keep on consuming and thus boosting the profits of the businesses the top folk own. This is a nice game for the rich as long as it lasts. Here in the US that would be the past forty years or so.

This is really simple.

It explains why our economic policies focus on preserving creditors, bailing out lenders, and keeping the inflation alarms ringing even when there is no inflation. Those policies benefit Read more…

Krugman on Piketty

April 15, 2014 10 comments

from Edward Fullbrook

Now Paul Krugman has gotten into the Piketty act.  The just published issue of the New York Review of Books features a long  review essay by Krugman (it’s open-access) on Capital in the Twenty-First Century.   Here is how it begins.

Thomas Piketty, professor at the Paris School of Economics, isn’t a household name, although that may change with the English-language publication of his magnificent, sweeping meditation on inequality, Capital in the Twenty-First Century. Yet his influence runs deep. It has become a commonplace to say that we are living in a second Gilded Age—or, as Piketty likes to put it, a second Belle Époque—defined by the incredible rise of the “one percent.” But it has only become a commonplace thanks to Piketty’s work. In particular, he and a few colleagues (notably Anthony Atkinson at Oxford and Emmanuel Saez at Berkeley) have pioneered statistical techniques that make it possible to track the concentration of income and wealth deep into the past—back to the early twentieth century for America and Britain, and all the way to the late eighteenth century for France.

INET — marginalizing heterodox economics rather than transforming the discipline

April 15, 2014 Leave a comment

from Lars Syll

In a report published by The Association for Heterodox Economics, INET is criticized for actually marginalizing heterodox economics:Big-vs-Small

Our main concern is that the positive potential of INET is steadily being closed down. What began as recognition of fundamental problems that require fundamental change is becoming a more modest set of alterations. A sense of failure is, for all intents and purposes, being translated into a context of relative success requiring more limited changes – though these are still being seen as significant. Part of the reason that they are seen as significant is that changes from within mainstream economics do not have to be major in order to appear radical. It is our contention that heterodox economics is being marginalised in this process of ‘change’ and that this is to the detriment of the positive potential for transforming the discipline …

Marginalising heterodoxy creates problems for teaching economics as a discipline in which economists constructively disagree and can be in error. This is important because it is through a conformity that suppresses a continual and diverse critical awareness that economics becomes a dangerous discourse prone to lack of realism, complacency, and dogmatism. Marginalising heterodoxy reduces the potential realisation of the different components of economics one might expect to be transformed as part of a project to transform the discipline …

The betrayal of the intellectual

April 15, 2014 1 comment

from Robert Locke

It is very difficult for historians to establish any set of ideas when confronted by people who are historically ignorant.  Recently I wrote, in a the RWER Blog that economics has never established a scientific paradigm  in its discipline.  So the idea that neoclassical economics did and that it is now being challenged is false.  It never did achieve paradigm status.  Twenty-five years ago (1989) I said the same thing in the first two chapters of Management and Higher Education Since 1940 (Cambridge University Press).  In the first chapter, “The New Paradigm,” I wrote about the attempt  Read more…

Unemployment in Europe: the totally stunning regional differences

April 15, 2014 Leave a comment

‘Totally stunning’: two hyperboles. But I had to use them. Could anybody only six years ago have imagined a Eurozone core with 4% unemployment or less (here the new regional unemployment data) and a southern periphery with large areas with unemployment of over 30%. Broad unemployment in these regions must be somewhere between 35 and 40%. Hey, Andalucia has 36% normal unemployment… Mind that inflation is going down in the core, too. Unemployment percentages of 3 to 4% are i.e. totally feasable.


Mind also that borders between countries do explain part of the differences. But only a part. Mind also that unemployment in Eastern Germany is finally becoming less high – but it took, despite lavish transfers, almost 25 years and mass migration before this happened. The ‘Wirtschaftswunder’, based upon debt redemption and equality, worked better than neoliberal internal devaluation (in the fifties unemployment went down from about 12% to about 2% in 9 years).

“Meritocratic Extremism”

April 14, 2014 2 comments

from Edward Fullbrook

Merijn is ahead of me as I have only just ordered Thomas Piketty’s Capital in the Twenty-First Century. The book is receiving masses of favorable media attention in the West, including from The New Yorker, the Financial Times, the Economist and The Observer where yesterday Piketty and his book occupied the cover of the newspaper’s review section. This attention is surprising given the book’s central message (one often expressed on this blog), that capitalism has now failed the world and that inequality is now accelerating at a very dangerous pace and that the rule of the ultra-rich over the everyone else is a form of gangsterism. The Observer’s feature writer went to the École d’économie de Paris to interview Piketty, and here are a couple of quotes.

Piketty’s dataset: part of a trend which is changing economics.

April 14, 2014 Leave a comment

Update: via Business Insider: this 2012 Cato Institute report by Steve Hanke and Nicholas Krus which, starting in France in 1796, carefully lists all 56 known episodes of hyperinflation (21 of which were connected with demise of Soviet Union and Yugoslavia).

I’m reading Thomas Piketty’s book about wealth, capital and inequality. At this moment one remark:

His book is based upon a very extensive ‘open source’ dataset which spans the centuries and the globe (wealth, return on capital, labour share, share of capital etc.). This seems to be part of a trend as Piketty is not the only economist who does this. Other examples are:

Carmen Reinhart and Kenneth Rogoff with their ‘This time it’s different. Eight centuries of financially folly‘ dataset, which spans the centuries and the globe (debt).

The late Angus Maddison data on GDP  (dataset continued by ‘a group of close colleagues’) which span the millenia and the globe

The Bank for International Settlements with their recent dataset on house prices which span decades (for Norway: centuries) and the globe.

The (real) wages datasets of the International Institute of Social History (moderator: Jan Luiten van Zanden) which span the centuries and the globe.

These datasets are changing or did already change the science of economics. A common theme: there is no such thing as a stable monetary capitalist economy.

I do think that, as long as we have the Sveriges Riksbank prize in economics science in memory of Alfred Nobel, the founding and maintenance of such datahubs should be one of the arguments to award the prize.

The ECB is failing its own, flawed, goals

April 13, 2014 Leave a comment

One of the functions of the 2% Eurozone inflation target of the ECB is to make processes of internal devaluation easier. This should, according to the ECB, be possible without outright deflation of the price level.  According to the 2011 ECB manual ‘The monetary policy of the ECB‘ (161 pages):

Taking the existence of unavoidable inflation differences into account, it has been argued that the ECB’s monetary policy should aim to achieve – over the medium term – an inflation rate for the area as a whole that is high enough to prevent regions with structurally lower inflation rates from having to meet the costs of possible downward nominal rigidities or entering periods of protracted deflation. According to all available studies, a rate of inflation below, but close to, 2% for the euro area provides a sufficient margin also in this respect.

In other words: 4% inflation in the Netherlands and Germany is necessary to enable Spain and Portugal and Greece and Italy to lower their price level relative to the Dutch and German level without having to lower nominal wages. That’s what this is all about. One can wonder if such a policy is effective anyway. As a recent ECB working paper states: Read more…

A Pedagogical Paradox

April 12, 2014 13 comments

from Asad Zaman and the WEA Pedagogy Blog

What is really strange is the contrast between the strength of the arguments against conventional economics, and difficulties involved in teaching common sense. It is like someone who has been convinced that day is night, and great effort is involved in pointing out the sun to him. I sometimes give the following example.

Look at that old lady purchasing tomatoes. You know what she is doing? She is differentiating a multivariate utility function and setting up a simultaneous equations system of first order conditions. Now she is solving the nonlinear system. Fantastic, she just solved it to find the utility maximizing purchase under budget constraints is exactly 12.8 oz of tomatoes. Alas, she cannot slice them with such precision, and does not know the integer programming techniques required to solve the more complex optimization problems. OOPS, she miscounted the money she paid, and did not notice the change in the budget constraint when the greengrocer shortchanged her.

While this is usually good for a few laughs, especially from deeply indoctrinated students, because we are poking fun at the sacred principle of utility maximization, there is a serious point involved. Our personal experience, observations of others behavior, and general knowledge of how markets and shopping works, provide overwhelming evidence against microeconomic theory of consumer behavior. Yet we set it all aside when we read Samuelson. If a Nobel prize winner said so, it must be right. My survey which provides a summary of this evidence is linked below:
The Empirical Evidence Against Neoclassical Utility Theory: A Review of the Literature” [with Mehmet Karacuka] International Journal for Pluralism and Economics Education Vol. 3 (4) 2012, p 366-414

As a group, why are we such complete failures at persuading the public of something which is plain as the sun? I have the following hypotheses:  read more here


The unpleasant political arithmetic of Greek bonds (2 graphs)

April 11, 2014 Leave a comment

Greek bonds fly of the shelves‘. Yesterday, Greece successfully issued 3 billion 4,95% bonds – and I’m still not seeing that one coming. Greece does not need new debt to be able to pay its interest bill. It needs frontloaded debt reduction to get debts down to a sustainable level, i.e. 60% of 2015 GDP (conservatively estimated, i.e. taking 0% growth and 3% deflation into account).Credible measures and structural reforms to make the remainder of the debt more flexible (i.e. ‘deflation protected’ bonds) have to be put in place. Tax measures – like a land tax – which increase the velocity of the stock of wealth and induce market oriented and demand boosting use of this wealth have to be introduced. Read more…

A simple proposal to kill high frequency trading in the stock market

April 11, 2014 5 comments

from Trond Andresen

Due to technological possiblities, success in stock market trading has increasingly become dependent on being at the front of a rat race in software, computing capacity and fast optical cable connections. While the firms whose stock is traded obviously do not change their prospects over time horizons shorter than days or even months, to win in the stock selling and buying game, today you have to act and react on a time scale of fractions of milliseconds. Automated high frequency trading (HFT) enables this. This race has now become so absurd that even the business press and financial regulators and pundits have become critical to it. One technical measure against HFT that has been implemented by a new stock exchange, IEX, is that all traffic go through a roll of cable (!) that delays the signals so much that HFT trading cannot profit parasitically from orders given to that exchange.

Here follows a simple proposal which does not depend on any changes to physical infrastructure, can be mandated by regulators and implemented easily at any exchange, and which enables not only the blocking of trading on millisecond scales, but can remove trading on any time scale that is considered too short. Being implemented as software, it also has the advantage that its parameters can be easily adjusted based on how the system performs. This solution does not presuppose any transaction fee, and it impacts small and big trade(r)s in the same way. Read more…

Economics textbooks on ‘capital’ — how to get away with scientific fraud

April 11, 2014 Leave a comment

from Lars Syll

It is important, for the record, to recognize that key participants in the debate openly admitted their mistakes. Samuelson’s seventh edition of Economics was purged of errors. Levhari and Samuelson published a paper which began, ‘We wish to make it clear for the record that the nonreswitching theorem associated with us is definitely false’ … Leland Yeager and I jointly published a note acknowledging his earlier error and attempting to resolve the conflict between our theoretical perspectives … However, the damage had been done, and  Cambridge, UK, ‘declared victory’: Levhari was wrong, Samuelson was wrong, Solow was wrong, MIT was wrong and therefore neoclassical economics was wrong. As a result there are some groups of economists who have abandoned neoclassical economics for their own refinements of classical economics. In the United States, on the other hand, mainstream economics goes on as if the controversy had never occurred. Macroeconomics textbooks discuss ‘capital’ as if it were a well-defined concept — which it is not, except in a very special one-capital-good world (or under other unrealistically restrictive conditions). The problems of heterogeneous capital goods have also been ignored in the ‘rational expectations revolution’ and in virtually all metric work.

Some links, 10/4/2014. Cooperations, energy (graph), Peter Praet (ECB) on the impossibilities of monetary policy in the EZ

April 10, 2014 Leave a comment

The ILO is officially charged with promoting and estimating cooperatives:

Here a little about the new statistics on cooperations. Here a report about cooperations (mind that Goldman Sachs was a partnership until 1999):

As business organization, cooperatives contribute to economic development, generating more than 100 million jobs and securing the livelihoods of nearly a quarter the world’s population. Cooperatives provide an important channel for bridging market values and human values … The financial and ensuing economic crisis has had negative impacts on the majority of enterprises; however, cooperative enterprises around the world are showing resilience to the crisis. Financial cooperatives remain financially sound; consumer cooperatives are reporting increased turnover; worker cooperatives are seeing growth as people choose the cooperative form of enterprise to respond to new economic realities. This report provides historical evidence and current empirical evidence that proves that the cooperative model of enterprise survives crisis, but more importantly that it is a sustainable form of enterprise able to withstand crisis, maintaining the livelihoods of the communities in which they operate

Are New-Keynesians accidentally discovering Keynes?

April 9, 2014 5 comments

Are ‘New-Keynesians’ discovering Keynes? Paul Krugman links on his blog to an Eggertsson/Merohtra paper which allows the ‘natural rate of interest’ to fluctuate. Which actually sounds somewhat Keynesian. In new/neo/old classical thinking the natural rate of interest equilibrates, in the unspecified run, supply and demand in all markets, including the labour market. An idea which, according to Keynes, was not so much wrong but useless. David Glasner, on his ‘Uneasy Money’ blog, states about Keynes this (emphasis added):

Keynes did not conclude, as had Sraffa, that there is no natural rate of interest. Rather, he made a very different argument: that the natural rate of interest is a useless concept, because there are many natural rates each corresponding to a different the level of income and employment, a consideration that Hayek, and presumably Fisher, had avoided by assuming full intertemporal equilibrium.

This last assumption is, according to Eggersson and Merohtra, still crucial for ‘microfounded’ models (which are not founded upon micro-relations at all, but that’s another discussion, see the end). But adding even a little realism to the model leads the model away from equilibrium, even in the long run…

In Summers’ words, we may have found ourselves in a situation in which the natural rate of interest – the short-term real interest rate consistent with full employment – is permanently negative … It may seem somewhat surprising that the idea of secular stagnation has not already been studied in detail in the recent literature on the liquidity trap, which does indeed already invite the possibility that the zero bound on the nominal interest rate is binding for some period of time due to a drop in the natural rate of interest. The reason for this, we suspect, is that secular stagnation does not emerge naturally from the current vintage of models in use Read more…

The capital controversy — when ignorance is bliss

April 8, 2014 1 comment

from Lars Syll

The production function has been a powerful instrument of miseducation.   The student of economic theory is taught to write Q = f(L, K) where L is a quantity of labor, K a quantity of capital and Q a rate of output of commodities. He is instructed to assume all workers alike, and to measure L in man-hours of labor; he is told something about the index-number problem in choosing a unit of output; and then he is hurried on to the next question,  in the hope that he will forget to ask in what units K is measured. Before he ever does ask, he has become a professor, and so sloppy habits of thought are handed on from one generation to the next.

The english recovery (?)

The ONS has published a new report on the recovery (?) of the UK economy. Some snippets:

While aggregate output has grown strongly in recent quarters, Figure 2 suggests that GDP per capita – a measure of output per person in the economy – has only recently started to recover. This difference is particularly pronounced in Panel B of Figure 2. While GDP has closed on the predownturn peak, GDP per capita remains some 6.1% below the level in Q1 2008, and is little higher than the level first achieved in early 2005.

Also, 72% of the increase of the number of self-employed was caused by an increase in the number of self-employed of 50 years and over of age, about half of these were over 65.

Unemployment: is there always a market clearing price? (Netherlands very long run edition).

April 7, 2014 4 comments

Frances Coppola has an interesting post on ‘why labour markets don’t clear‘. She points to the fact that during downturns,

the market-clearing price of labour can fall to below the minimum needed to sustain life.

When wages are at starvation level, hours worked, labour force participation rate and workforce size all decline as people become weak, ill and eventually die – or, if they can, leave for somewhere more prosperous.  Reducing the size of the workforce means that the market will eventually clear and wages start to rise again – for those who have survived.

This is the fundamental flaw in the “sticky wages” argument. In an economic downturn, the labour market cannot clear without incurring unacceptable social costs. Malnutrition, starvation, disease and death are the  consequences of freely falling wages in an economic downturn. The reason why labour markets don’t clear is because we don’t want them to.

I do not entirely agree. Let’s take a look at the Netherlands.

How not to win an economic argument

April 7, 2014 9 comments

from Steve Keen

A critique of a yet-to-be-published paper of mine (“Loanable Funds, Endogenous Money and Aggregate Demand”, forthcoming in the Review of Keynesian Economics later this year; the link is to a partial blog post of that paper) by non-mainstream economist Tom Palley reminds me of one of my favourite ripostes by a politician, back in the days before spin doctors stopped them saying anything offensive — or indeed anything interesting.

As Sir Robert Menzies, former Australian prime minister and leader of the conservative Liberal Party, was giving a campaign speech in 1954, a heckler called out “Mr Menzies, I wouldn’t vote for you if you were the Archangel Gabriel”. Menzies shot back: “Madam, if I were the Archangel Gabriel, you would not be in my constituency.”

So it is with Tom’s critique. He criticises me for a whole range of things that I didn’t discuss, that he thinks I should have discussed, and for techniques I used that he thinks I shouldn’t have used. But Tom wasn’t in my intended audience for this paper — and not because he “wouldn’t be in my constituency”, but because he is. We have our differences, but we’re generally on the same side on the topic of this paper — and I didn’t write it for people who agree with me, but for those who don’t on two key issues: the role of banks, debt and money in the economy, and the role of the change in debt in aggregate demand.

Lower relative and even absolute wages did not lead to lower price levels in the Eurozone, up to 2012

Do lower relative or even absolute wages lead to a lower absolute or price level, as implied by the at least some of the versions of the ‘New Keynesian pricing Equation‘, other things, like total employment, equal? No, they don’t. At least not in the short or even the medium run. 2012 wages in Portugal and the UK (Euro price level) were about as high as in 2004. Greek wages were even lower (and continued to decline in 2013…). But the price level in these countries increased about as much as the price level in other EU countries.  This is an important fact. It means that slashing wages leads to a massive erosion of purchasing power, with, of course, dire consequences for expenditure, employment and all that. Employment won’t be equal and its decline will aggravate the slump. It’s a very Old Keynesian situation.
