The Economist is concerned with debt-deflation

Or so it seems (see here; subscription required). They say: "If falling prices endure, then debts, fixed in nominal terms, are harder to pay." Indeed. As Keynes had said back in 1936: “if the fall of wages and prices goes far, the embarrassment of those entrepreneurs who are heavily indebted may soon reach the point of insolvency, — with severely adverse effects on investment.”

In other words, if prices fall, indebted agents owe in real terms more than before. This could affect both firms and consumers. If the price of houses fall, but the mortgage debt remains the same, consumers own more debt in real terms and consumption might fall. In the same vein, if prices are falling and the firm nominal debt is fixed, the real debt increased and investment might decline. Keynes emphasized the role of investment. The sequence of events is given by:

The U.S. Federal Reserve and Shared Prosperity

By Thomas Palley

The Federal Reserve is a hugely powerful institution whose policies have an enormous effect throughout the economy. For that reason, it is doubtful the United States can achieve shared prosperity without the policy cooperation of the Fed.

Now, with the economy stronger, there is debate over whether the Federal Reserve should raise interest rates. That conversation is important, but it is also too narrow.

It keeps policy locked into a failed status quo which has seen the Fed consistently take care of Wall Street first, while placing the concerns of Main Street a distant second. Though the Great Recession has triggered some policy shift toward helping ordinary Americans, much more is needed.

Jean Tirole is afraid of heterodox economics

Jean Tirole says heterodox economics encourages "relativism of knowledge" and is "the antechamber of obscurantism." The response from the Association Française D'Économie Politique (AFEP) is here. The context is the creation of a new section of the National Council of Universities (CNU), which would incorporate heterodox approaches to economics, which was discussed here and here before.

Tirole suggests that unless you publish in mainstream journals, and get the approval of people in authority, that won the "Nobel" (Bank of Sweden), Clark or the Yjro Johannson award, you should not count. Heterodox economists are basically: "a disparate group, in trouble with the assessment standards that are internationally acknowledged."

He uses his authority as a "Nobel" winner, to reduce the space for alternative views on the functioning of the economy. Note that in his pursuit of closing spaces for heterodox economists, which would not per se …

Call for Papers: URPE Reader

The Union for Radical Political Economics (URPE) has put a call for papers for the new reader. The last reader was titled Political Economy and Contemporary Capitalism and was published in 2000. I had a chapter on trade and finance (here). It provided an alternative to the mainstream in a variety of topics, including foreign financial crises, health care, social security, and welfare reform, while at the same time demonstrating the variety of heterodox (alternative) approaches available to economic inquiry. It was essentially an academic tool showcasing the latest work in heterodox research. This would be an excellent opportunity for young scholars, and very welcome for those teaching economics, in particular after the failure of the mainstream regarding the 2008 Global Crisis.

Honey, I shrunk the middle class

The definition of middle class jobs is arbitrary and not particularly good. From the NYTimes story, it seems it's basically wages between 35 and 100k per year. At any rate, less jobs in manufacturing and more in services, particularly in health jobs, like nurses. Also, a gender bias, with an increase in female participation in the middle income jobs. And yes, increasingly these jobs require a college education. So more nurses and less machine operators, or something like that. The problem is that with this the size of the middle class is effectively shrinking (see graph below).
This suggests that the majority in the US is not middle class anymore. The divided society between the haves and have nots is becoming the defining characteristic of the US.

It's all up to Merkel: Galbraith on the Greek Crisis

"Is Greece’s fate in the hands of Angela Merkel? One leading economist with close ties to Greek finance minister Yanis Varoufakis says that the primary obstacle to compromise is a dramatic division within the German government, with one faction demanding that Greece fully adhere to its previous commitments, and another powerful group advocating compromise."

PS: Listen also to this interview here.

PS': And Jamie thinks that the agreement was good, as I did notice Saturday that it was Mario Nuti's and my own view.

On the blogs

Kakistocracy -- Mario Nuti on the Greek negotiations, up to the agreement reached the other day. Note that he sees the extension as a good thing. So do I. I don't think Greece caved, as many on the left have been saying. This is an agreement were everybody can claim victory. Greeks got more time, which they need, Germans didn't make concessions, at least not very early in the process.

Warning: too much finance is bad for the economy -- The Economist, following research from Cecchetti at the BIS. And yes they are right, but for the wrong reasons. Finance hurts not because the genius that would have gone to physics ends up in the hedge fund. The reason is too much unregulated finance is prone to crisis.
Human Capital Controversy -- David Ruccio on the debate that followed Branko Milanovic's post on ditching human capital, with Nick Rowe among others.
Graph/Table of the Week: Wage Compression -- The URPE post, with a link to Ezra Klein's discussion of the Obama economy.

Economy-Sapping Patent Trolls or the other Vultures

The question of whether patents promote or hinder economic progress is unresolved and probably divides the profession. Not always according to orthodox/heterodox lines, I might add. I'm a patent agnostic, as you would know from a few posts (see here or here), in particular because I'm skeptical about the role of property rights in general in promoting innovation, and because I tend to believe in the role of expanding demand in technological innovation.

My reading of the evidence is that patents delayed the development of the steamboat, for example, often considered the first major American contribution to technological progress. The thing is that the notion that patents stimulate innovation is based on a sort of hero or great man theory of history, the god like figure that invents a solution out of nothing and transforms the world. This does not describe the messy, incremental process of technological development that seems to be behind every economically significant innovati…

More Galbraith on Greece

From a short piece in the Greek paper Ekatherimini:
"So far, the Greek achievement consists of stating raw truths in rooms full of self-serving illusions. This exposes contradictions, bringing on facile ripostes, easily rebutted. It also brings on threats and menacing gestures, intended to test resolve. The Greek government seems to have met that test.  It can now proceed to the next step.  The next step is to define carefully what may be accepted. As for reforms, as much as 70 percent of the previous memorandum is (and always has been) common ground. That which is not – fire-sale privatizations, destructive labor market liberalizations and the unreachable 4.5-percent target primary surplus – can be spelled out. Reasonable language to describe the process of discussion to follow may be found." Read the full article here.

Galbraith on the Greek negotiations

A short interview given Tuesday morning from Brussels to Greek television. The questions are in Greek but the answers are in English and fairly direct. Not very good news, and not unexpected either. Basically the Germans are blocking a solution. What is needed to get a solution? "Calm and courage," says Jamie.

Lazzarini on the second phase of the Cambridge-Cambridge capital theory controversies

A new paper by Andrés Lazzarini on the second phase of the capital debates, from 1971 to 1976, when the intertemporal Walrasian model had become the norm within the mainstream. From the abstract:
The aim of this paper is to clear up some issues in a second phase of the Cambridge-Cambridge capital theory controversies, when the neoclassical argument was chiefly conducted in terms of the Walrasian specification of capital in intertemporal and temporary general equilibrium models. It is held that the response by the neoclassical side in that phase has not been as satisfactory to rebut the implications of reswitchingand capital reversing as some neoclassical scholars have argued. The reason for this can be traced in the overlooking of the implications of the redefinition of equilibrium implied in those models. Read full paper here (subscription required). I think this might be an earlier version here.

Lucas on the European Monetary Union

This is a bit old, it's from the interview in Snowdon and Vane's Modern Macroeconomics. The questions and answers for the Monetary Union below. Note that this is an interview from 1997.
S&V: What are your views on European Monetary Union?
Lucas: Again I don’t know enough about the politics, which has to be central.

S&V: Does it make economic sense to you?
Lucas: Well, it’s an issue in inventory theory. The cost of dealing with multiple currencies is that if you are doing business in Europe you, or people you hire to help you, have to have stocks of inventories of a lot of different currencies because payments are coming due in a lot of different currencies. The inventory cost of holding money is the interest foregone you could have earned by holding interest-bearing assets. If you have a common currency you can consolidate your cash inventories so that there is a saving involved. That is a very modest saving, but it is positive. But obviously multiple currencies are not…

Kevin Gallagher on Emerging Markets and Re-regulation of Cross-Border Finance

"Since the revival of global capital markets in the 1960s, cross-border capital flows have increased by orders of magnitude, so much so that international asset positions now outstrip global economic output. Most cross-border capital flows occur among industrialized nations, but emerging markets are increasing participants in the globalization of capital flows..."

Sraffa's contributions to economics: a crash course

So a friend asked what to read in order to understand Sraffa's contributions to economics. For some reason the Production of Commodities by Means of Commodities is considered a very difficult book to read. I find that a strange argument. It is similar to the notion that the General Theory is a badly written book, as in difficult to follow (not necessarily the content, but the style), since supposedly Keynes was not a good writer (he actually was a bestseller author, at least his Economic Consequences of the Peace, and a prolific writer for the general public, meaning clear and popular).

Sraffa's book explains in plain English most of the essential concepts in his book. I would suggest the reading Part I as one that can be taken without any problem for those with some basic training in linear algebra. In addition, below I'm posting the links to 7 previous posts on Sraffa's contributions to economics, which might be helpful for some.

On the blogs

Wynne Godley’s Prediction of the Failure of the Eurozone -- Lord Keynes on Wynne's euro skepticism. I posted on this here. Worth noticing that Wynne was very much for the European Union, and not against monetary union per se. He argued that fiscal union (which means political union) should come first.

Review of James Galbraith "The End of Normal" -- by yours truly, but in Portuguese.
Junk the phrase 'human capital' -- Branko Milanovic on why the term is "ideologically motivated and has contributed to conceptual confusion." Mind you, you must junk also the conventional understanding of capital, but that's another story.

Graph/Table of the Week: When did Corporate America begin? -- my regular short post on the URPE blog, based on a graph by Alfred Chandler. His story of why we got the big corporation. In his words:  "The new, more reliable, high-volume, regularly scheduled, all-weather transportation and communications provided by the…

Crowding out: what's the evidence?

Before the publication of Keynes' General Theory, most marginalist economists were against expansionary fiscal policy. It was believed that an increase in government spending would reduce by the same amount private spending, and, hence, it would have no effect on output and employment. Keynes referred to this as the Treasury View, since bureaucrats at the Treasury were prone to believe it. This has been known as crowding-out in more recent times.The evidence is not particularly forthcoming, as far as I can tell.

Amazingly, given the relevance of the topic for conservative ideas, and the fact that this is still the reason why the fear of deficits and debt is so pervasive, there is not much research on the effects of deficits on interest rates. Robert Murphy, on the Instructor's Resources for Mankiw's manual (funny that is NOT in the manual) says:
"Economists worry, therefore, that high deficits imply low levels of investment, leading ultimately to a lower capital stoc…

Teaching macroeconomics: the resilience of the ISLM model

Teaching ISLM this and next week. I have posted in the past on this, so I'll just put the links below to the relevant posts.

ISLM: What is it good for?

ISLM: a further explanation and a defense

Krugman is actually right on ISLM and Minsky

There are more posts that deal with some relevant issues that you can access if you click on the ISLM label below.
The interesting thing is that, although the ISLM is less used in theory, in particular because the multiplier story at the core of the IS has been substituted by a Ramsey intertemporal maximization story and the LM has been substituted by a Wicksellian interest rate rule, it is still the workhorse of macroeconomic teaching, and likely of simple policy thinking. In many ways the ISLM remains a much better basis for thinking about the economy than modern New Keynesian DSGE models (if nothing else because of the multiplier).

Inequality and education

Nope, I'm not going to discuss the relationship between access to education and inequality. And yes the mainstream usually gets causality wrong and argues that education is the solution for reducing inequality (it's more likely that education is more accessible with lower inequality). I'm talking about the graph below from The Economist.
So the top 10% Universities hold 70% of all the endowments. The eight Ivy League universities hold 21% of the endowments. And the rich universities hold more stocks, mainly in US markets, than the endowment challenged ones. I guess, there must be a high correlation between the universities where the Fortune 500 CEOs went and the top endowments.

On the blogs

Debt Is Money We Owe To Ourselves -- Paul Krugman gets debt right, and uses the example of the UK discussed here before. And yes he is right: "the problems with public debt are also mainly about possible instability rather than 'borrowing from our children'." I would add particularly when it's in foreign currency, like in Greece.

Talking about Yanis on the BBC -- Steve Keen on Yanis Varoufakis and the Greek crisis.

Beyond the headlines -- David Ruccio on why the 257,000 new jobs in January announced yesterday by the BLS are not as good as you might think. Similar to the discussion by Dean Baker here and myself here on the recent GDP news.

Bracing for another storm in emerging markets -- Kevin Gallagher thinks the Chinese slowdown will bring commodity prices down, and coupled with higher interest rates in the US spells doom for developing countries. I'm less sanguine about that scenario. But we'll see soon enough.

Multiplier-Accelerator and Business Cycles

That would be long indeed (100 years or so for the US)
Keynesian theories of the business cycle start from the notion that the changes in income equilibrate savings to investment, and the level of activity is determined by effective demand. In that sense, the economy can fluctuate in the long run, with wage and price flexibility, around a normal position that is below full utilization of labor and capital. Unemployment is the norm. Keynes was not concerned in the GT with business cycles per se, even though he discussed the issue at the end of the book. His main concern was with what he referred to as unemployment equilibrium. It is clear in his terminology, unemployment equilibrium, instead of disequilibrium as Patinkin suggested would be more appropriate, that Keynes meant that unemployment was not the result of some type of imperfection, wage or interest rate rigidities, for example, which became the leading explanation for unemployment among the mainstream Neoclassical Synthesis o…

Dean Baker on the need for larger deficits and junk economic science on Chris Hayes

And of course on the slow recovery. In his words, "we are still bound by the Age of Austerity." It's worth insisting, since pressures for more contractionary monetary policy are mounting. Hayes bit is more generally about GOP's contradictory complain about inequality and the new Obama budget, which is more progressive than his previous ones. And yes they do talk about Big Government Republicans, but not enough in my view about small government (and pro-Wall Street) Dems. For more on that go here.

Last quarter growth not impressive, and slow recovery continues

I was writing about this Friday, but other post took precedence. As noted in my links to other blogs, Dean Baker dealt with this in the context of the NYTimes coverage of the news. According to the BEA last release: "Real gross domestic product -- the value of the production of goods and services in the United States, adjusted for price changes -- increased at an annual rate of 2.6 percent in the fourth quarter of 2014, according to the "advance" estimate released by the Bureau of Economic Analysis. In the third quarter, real GDP increased 5.0 percent." In other words, after two quarters of faster growth at 4.6% and 5%, the last quarter has been less impressive, and the overall growth rate for 2014 was at 2.4%.  Note that even those two faster quarters have to be taken with a grain of salt, since the first quarter had negative growth, and the subsequent ones seem higher for that reason.

This should deflate the overly confident views on how fast the economy is reco…
