MMT AND THE EURO: Are Current Account Imbalances to Blame for the Euro Disaster? Part 1

Two weeks ago I cited Paul McCulley’s claim that MMT got it right. I followed that up last week with Brad DeLong’s claim that we’re all Minskians now. Well, most of us, anyway. Is MMT on a roll? Well, maybe not, if you listen to the critics.

In particular, an Italian economist, Sergio Cesaratto called the MMT victory “spurious”. (http://nakedkeynesianism.blogspot.com/2012/07/spurious-victory-of-mmt.html) I’ll try to focus in on the main complaint, which seems to be that MMT missed the true cause of the Euro mess: current account deficits run up by some profligate EMU members.

Over at NEP, I have just offered up a number of early examples of MMT analyses that in my view “got it right”: http://neweconomicperspectives.org/2012/07/mmt-the-euro-and-the-greatest-prediction-of-the-last-20-years.html. I won’t repeat all of them here as I am going to focus directly on what I see to be the causes of the crisis and link that back to the argument that it is all due to current account imbalances.

Sorry, this is going to be a long and wonky piece, as befits a complex and still unfolding disaster. And it will come in two parts.

First, is it true that MMT has ignored current account problems within the EU and EMU?

Here’s one of the quotes I used, from Jan Kregel:

“Germany appears to have adopted a policy of controlling the growth of nominal wages at a rate that is below its domestic productivity growth. German unit labor costs have been falling …. If Germany does in fact manage, as it seems to have been doing for about two years, to continue to decrease its unit labor costs at 5 percent — that is, at rates that are substantially below those in the other European countries, with no longer a possibility, as has been the case in the past, for the deutschemark to revalue relative to the other currencies — this means that if I am a manufacturer or a government in a non-German European country, I am going to experience declining profit margins until I also manage to compress my unit labor costs.” (This is from a presentation Jan made at an early MMT conference organized in London by Warren Mosler, and published in The Launching of the Euro, Proceedings of “A Conference on the European Economic and Monetary Union,” Annandale-on-Hudson, N.Y.: The Bard Center, 1999) 

Well, that is precisely what Germany did for the next half dozen years—helping to fuel current account deficits on the periphery; and Jan also predicted the deflationary impact Germany would impose on Euroland. In 1998. Here is another quote from Jan, this time from an article published in the Eastern Economic Journal, Winter 1999; this was presented at a panel on the Euro organized by Mat Forstater. Jan’s main point was that the construction of the EMU would create deflationary forces that would result in chronic high unemployment; he thus proposed to use the “modern money” approach to formulate a policy response—an employer of last resort program for the EMU. Here I will remain focused on the current account imbalances and the problems these would create (you can read his paper for the ELR proposal for the EMU):

“If France or Italy decided to expand domestic demand, it would be quickly drained out of the country—it would no longer show up in the German balance of payments surplus and an Italian deficit as before EMU, but now appear as increased expenditure flows from Italy to Germany, with the Italian fiscal deficit deteriorating, and credit risks on Italian securities increasing. While both labor and capital costs will be rising in Italy relative to Germany, this will only exacerbate the divergences and make a policy of downward wage convergence more pressing. The single currency will bring the positive benefit of releasing European economies from having to contract their domestic expenditure policies to defend their exchange rates relative to the DM, but it brings with it the cost of requiring that they contract their nominal wages to defend the competitiveness of their domestic production against cheapening German imported goods.”

If that is not prescient, I do not know what is. But wait, there’s more. Kregel examines the possibility that the EMU can resolve internal current account imbalances by exporting outside the union (ie: exporting unemployment abroad):

“The question is whether the increase in demand from outside the European Union resulting from real depreciation of the EURO will be sufficient to offset the decline in internal demand. Whereas external trade was a very large proportion of each member country’s GDP before unification, it will become a very small proportion after unification. The order of magnitude is not likely to be sufficient to offset the reduction in EU demand. Further since the Euro will float against the dollar and the yen, and given the German obsession with a ‘strong’ euro as evidenced in recent Bundesbank policy, if the Euro were to appreciate relative to these currencies this would eliminate any benefits that might have accrued from the reduction in unit labor costs. If the Euro behaves as the German mark has done over the last twenty years, this means that in the medium term it will appreciate so as to maintain a roughly constant real effective exchange rate, with nominal appreciations offsetting any changes in relative unit labor costs.”

So we were indeed looking at the potential for current account imbalances once the Euro was launched.

More specifically, the way we have usually introduced the current account balance is through Wynne Godley’s sectoral balance approach (which I have explained previously on the GLF and there are many other explications over at NEP and at www.levy.org).  For a particularly instructive piece, here is Rob Parenteau’s 2009 take on the macroeconomic identity which states that the domestic private sector balance plus the government balance plus the foreign balance must sum to zero:

“…a trade surplus is the only way both the GFB [government balance]and the PSFB [domestic private balance] can maintain a net saving position at the same time (assuming for whatever reason that was a worthy goal), but at least it is a promising start at representing how sectoral financial balances are related, and it reveals many of the misconceptions that unnecessarily cloud the debate.” http://neweconomicperspectives.org/2009/07/employing-krugmans-cross-farewell-mr.html

The reason I am pointing readers to Rob’s work is because he went on to extend a simple model created by Paul Krugman specifically to examine the problems in Euroland. Since 2009 Rob has been examining these current account imbalances within the MMT framework. For a very good exposition of this model and charts on the EMU members’ sectoral balances, see Mitch Green’s powerpoint here: http://www.slideshare.net/MitchGreen/adding-the-domestic-private-sector-financial-balance

I will present some of the data next week.

I find it perplexing that Sergio thinks MMT has overlooked current accounts and the link to financial crises that first hit the US and then moved on to Euroland. Wynne and I wrote a couple of pieces together back during the Clinton years warning that the combination of a current account deficit plus a budget surplus meant that Goldilocks was going to get murdered by the necessary balancing item—an unprecedented sustained private sector deficit. (You can find them at www.levy.org.) As Rob points out in the quote above, Clinton could have a budget surplus without burdening the private sector with debt only if the US could run a current account surplus. But that was not going to happen, due to the external demand for dollars.

And we rejected the claim that problems could be resolved by exchange rate adjustments—Wynne was always skeptical that dollar depreciation would do much to turn around the US current account deficit. (Now, full disclosure: Wynne and I had a different view about the desirability of reducing the US current account deficit. He would have preferred to reduce it; I wanted to ramp up fiscal policy to allow the domestic private sector to reduce its deficits.) From the MMT point of view (with which Wynne was otherwise quite sympathetic) the main problem with current account deficits in monetarily sovereign nations is the balance sheet situation of the domestic private sector (given a government budgetary outcome). In other words, the problem with the US current account deficits was the flip side of the coin: a private sector that was spending far more than its income for nearly a decade.

Now, some EMU nations also ran chronic current account deficits. And if these had been monetarily sovereign nations (in the sense that they each issued their own floating rate currency), then the worry would have been over the private sector balance. But here the EMU nations diverged significantly from one another—some with current account deficits did not run up huge private sector debts, others did. The balancing item, of course, was the government balance. And, more importantly, these were not monetarily sovereign. Each dropped its own currency in favor of a “foreign” currency—the Euro. So there are two issues: a current account deficit mostly offset by a private sector deficit, versus a current account deficit offset mostly by a government sector deficit. My argument is that for a monetarily sovereign nation only the first of these is a problem; but for Euro nations, either of these can cause trouble.

Now why am I making this distinction—between sovereign and nonsovereign nations (in the monetary sense)? Look at it this way. What is the current account balance between, say, Alabama and Idaho? Does anyone know? Does anyone care? They both use the Dollar. Yet, both Germany and Greece use the Euro and I doubt there is a single reader out there who does not know that Germany runs a positive current account against Greece. And most of them care. A lot.

To be sure, the imbalance among US states is important for some considerations—and regional economists study such things as regional multipliers (if you spend a dollar of fiscal stimulus in Kansas City, how much of the multiplier effect leaks out?). It is important for regional development and poverty alleviation. But the reason why the balance of payments numbers are not the subject of careful focus for others is because we use fiscal policy to try to overcome the negative effects on standards of living across states due to different multipliers and other factors related to these current account flows. Obviously, we do less than an ideal job—poverty rates, average wages, access to good jobs, and per capita incomes vary considerably across states. But Washington’s fiscal transfers are large both in terms of its spending on goods and services, its direct employment, and its spending on “transfer” payments (things like Social Security). And we are not going to kick, say, Alabama out of the Dollar Union because of its chronic balance of payments deficit.

US Federal government purchases amount to 20% of GDP; total spending is almost a third of GDP. It is big enough to do some redistribution to offset some of the current account deficits. The Euroland’s Parliament spends less than 1% of the GDP of Euroland; some of that does redistribute (check out the highways in Sicily, thanks to EU spending) but it is far too small to do the job of offsetting current account deficits. So most of the offset is up to the individual EU nations.

OK so that is part of the EMU’s problem—and note it is not a simple current account story. It is an MMT story about the constraints imposed due to the setup of the EMU, which separated fiscal policy from the currency. MMT has written about this problem since the beginning. Again, there are many quotes in my new piece at NEP; let me just repeat three examples, all from the earliest years of the Euro experiment.

The following is from my 1998 book, “Understanding Modern Money”: “Under the EMU, monetary policy is supposed to be divorced from fiscal policy, with a great degree of monetary policy independence in order to focus on the primary objective of price stability.  Fiscal policy, in turn will be tightly constrained by criteria which dictate maximum deficit to GDP and debt to deficit ratios.  Most importantly, as Goodhart recognizes, this will be the world’s first modern experiment on a wide scale that would attempt to break the link between a government and its currency. …As currently designed, the EMU will have a central bank (the ECB) but it will not have any fiscal branch.  This would be much like a US which operated with a Fed, but with only individual state treasuries.  It will be as if each EMU member country were to attempt to operate fiscal policy in a foreign currency; deficit spending will require borrowing in that foreign currency according to the dictates of private markets.”

This quote is from a 2002 article by Stephanie Kelton (then Stephanie Bell): “Countries that wish to compete for benchmark status, or to improve the terms on which they borrow, will have an incentive to reduce fiscal deficits or strive for budget surpluses. In countries where this becomes the overriding policy objective, we should not be surprised to find relatively little attention paid to the stabilization of output and employment. In contrast, countries that attempt to eschew the principles of “sound” finance may find that they are unable to run large, counter-cyclical deficits, as lenders refuse to provide sufficient credit on desirable terms. Until something is done to enable member states to avert these financial constraints (e.g. political union and the establishment of a federal (EU) budget or the establishment of a new lending institution, designed to aid member states in pursuing a broad set of policy objectives), the prospects for stabilization in the Eurozone appear grim.” http://www.cfeps.org/pubs/wp/wp24.htm

The final quote is from Mat Forstater, written in 1998 and published a year later: “Under the EMU, if investors are at all hesitant about any one member’s debt, they can buy another member’s debt without incurring currency risk, since there is no exchange rate variability among the currencies of member countries. Because member nations are now dependent on investors for funding their expenditure, failure to attract investors results in an inability to spend. Furthermore, should a member’s revenues fail to keep pace with expenditures due to an economic slowdown, investors will likely demand a budget that is balanced, most likely through spending cuts. In other words, market forces can demand pro-cyclical fiscal policy during a recession, compounding recessionary influences…. Even if there were no imposed limits on countries’ deficits and national debts, the structure of the EMU makes it nearly impossible for a country to enact a counter-cyclical fiscal policy even if there were the political will. This is because, by giving up their national monetary sovereignty, countries are no longer able to conduct coordinated fiscal and monetary policy, essential for a comprehensive and effective remedy to periodic demand crises. Why would countries voluntarily sacrifice the ability to conduct a coordinated macroeconomic policy, especially at a time when official unemployment rates are in double digits and there are clear deflationary pressures?” http://cas.umkc.edu/econ/economics/faculty/Forstater/papers/Forstater1999/IntroEuropeanEconomicMonetaryUnion

These all establish the main MMT position on the fundamental flaw with the set-up of the EMU. Clearly, the problem cannot simply be a problem of current account imbalances—we’ve got them all across the US states. And the US, itself, runs a chronic current account deficit. But the US federal government is sovereign, it issues its own currency. It helps to offset current account deficits among states through fiscal transfers; and it can never run out of its own currency no matter how big its budget deficit. It can set its overnight interest rate target wherever it wants—at zero if desired—and hold it there forever, if it wants. That lowers short term treasury rates, and Uncle Sam can—if he wants—issue only short term treasuries. All of these options are fully within the federal government’s sovereign power, although it can choose to do something else.

Individual EMU nations are in a wholly different pickle. They have no equivalent to Uncle Sam to provide significant funding; all they’ve got is an ECB whose stated and legislated mission is to AVOID providing the kind of support Uncle Sam provides to US states. (As we now know, when push comes to shove, the ECB uses “work arounds”, albeit while kicking and screaming.)

Now we come to the actual crisis that hit the EMU. All of the above is preliminary—necessary to understand that the system was vulnerable to crisis. And when Paul McCulley said we should declare victory, I think these analyses were what he was talking about. But where would the tsunami of a crisis come from? Well, we know the bad winds blew in from the west, in the form of trashy US mortgages. But for a while it looked like Euroland might get by with a few scrapes and bruises. Then it was hit with hell and fury—the crisis became a Euro crisis. So while we’ll accept some finger pointing at the US crisis, we want to get more specific about what went wrong in the EMU.

Let me borrow, again from my NEP piece. In order to judge how correct MMT was in its predictions, of course, we have to understand what went wrong in Euroland. Our argument was that separating fiscal policy from currency sovereignty would raise questions of solvency that would constrain the ability of fiscal policy to expand when necessary. That was the basis of all these early MMT arguments. But there was an additional angle: how would the crisis begin? Would it be a recession that no individual government could resolve by fiscal stimulus? Would it be chronic current account deficits of some member states (to the benefit of Mercantilists like Germany or the Netherlands)? Or would it be a financial crisis? Well, how about a Trifecta: all three at once?

I think all readers here now understand the problems raised by recession—so there is no need to go into that one in detail. As individual nations faced a downturn, their budgets would move sharply to deficits (as tax revenue fell and social spending rose) that would rise further above Maastricht criteria; markets would react with higher interest rates that would in turn raise deficits further in a vicious cycle. OK, that happened. And then, of course, we also found out that (Surprise! Surprise!) governments had already been manipulating accounting (thank you Goldman Sachs!) so their deficits had always been higher than supposed.

And we already addressed the current account story—easily understood through the lens of Godley’s sectoral balance approach: a current account deficit must be offset by a combination of a domestic private sector deficit and/or a government deficit. Since these are not sovereign currency issuing governments, private and government deficits can both lead to problems.

However, it is much more than a current account problem, as Rob Parenteau has shown. Any EMU nation can be blown up by its banks even while running a current account surplus. This is the “financialization” or “Money Manager Capitalism” story that comes from Hyman Minsky—probably well over 90% of cross-border finance has nothing to do with the current account, and it was that part of finance that blew up countries like Ireland and Spain. (We’ll turn to that because it is related to the issue.)

So, finally there was the financial crisis angle. So far as I know, Warren Mosler was the first to fully understand this. He was harping on it for as long as I can remember—I’ll present his argument in some detail next week as we turn to a close examination of the data and analysis that will help to disprove the thesis that it all comes down to current account imbalances.

Wray,

You have to be careful saying MMT is right so often. It's also been very wrong at times.

I went through some of those early Levy papers from the early 90's and noticed that you were very negative about the economy through most of then 90's. You even called it a depression on several occasions. Those were very bad calls given the boom that ensued.

Also, Warren Mosler was cited in the Washington Post article earlier this year for betting against a Russian default and having to shut down a $800 billion fund.

Lastly, your colleague Mike Norman very famously said there was no housing bubble in 2006 on national TV scoffing at Peter Schiff.

Since you proclaim MMT to have gotten so much right it's nice to offer the other side of the story as well since you guys have also gotten a whole lot wrong over the years.

"..countries that attempt to eschew the principles of “sound” finance may find that they are unable to run large, counter-cyclical deficits, as lenders refuse to provide sufficient credit on desirable terms" (Stephanie Kelton).

Perhaps we might put it this way, then:

Under EMU, countries that eschew sound finance (that is, PIGS) will be more constrained in their capacity to create money than commercial banks of the same countries.

That is truly a world upside down, and of the PIGS own making since no one forced them to enter the monetary union.

They went to their own demise through the application of the principles of free will. Ironic, indeed!

Jose ignores the political dimension of this currency union, which was to leverage and promote full political integration in a super state. The smaller EU members were largely coerced to enter the Eurozone and are now reduced to Soviet-style satellites with total dependence on the Core members. Even the healthier EZ members like Netherlands and Finland are beginning to resent this highly coercive system, where major decisions are made by unelected bureaucrats and policy is set by essential only two EZ members: France and Germany with all the others left either to put up or shut up…..

DiranMJuly 13th, 2012 at 8:28 am

Of course, I do not exonerate the debauched and corrupt Greek political elite and their criminal actions in joining the Eurozone when they were not ready and on falsified documents and Enron-style accounting. I do, however, see signification collusion and complicity on the part of the EU to accept Greece largely in knowledge of these matters partly for political reasons and partly for the EU crony capitalism.

Now they going together to hell in a hand basket, but at the expense of millions of hapless EZ citizens, paying a hefty cost in terms of the mass unemployment and severe recession for this highly flawed system.

LRWrayJuly 13th, 2012 at 12:15 pm

Hi "phil": The early 1990s were a "contained depression" as Wally Peterson put it in the title to one of his books; the US broke out in the Clinton Goldilocks euphoria that then set us up for the GFC. This is all analyzed thoroughly in my "money manager capitalism" papers that follow Minsky. Mike Norman has never been my "colleague"; he is on-board with modern money theory. I think I began doing interviews on his show around 2006 but I have no idea what he thought about the real estate bubble. I called it a bubble as early as 2000–which it was. If he said it was not, then we certainly disagreed. Warren did "bet" that Russia would not voluntarily default on its debt–but for political reasons the govt decided to do that. I've found that economists–even very good ones–often get the politics wrong. Finally, I don't know any economist anywhere who never got anything wrong. Good ones actually learn from mistakes; Chicago economists never do.

LRWrayJuly 13th, 2012 at 12:17 pm

You must have misunderstood the argument. Members of the EMU have no choice but to follow "sound finance"–just like a US state.

LRWrayJuly 13th, 2012 at 12:18 pm

Yep, they are paying the price of the mistake made by the founders of the EMU. It is shameful that the "leaders" are forcing austerity unnecessarily. The Economic Solutions are easy to see; admittedly the Politics are difficult.

LRWrayJuly 13th, 2012 at 12:23 pm

There was a TV program in Germany recently, titled roughly “The great euro hoax – when everyone deceives everyone“. Interestingly enough, it's about the historical background of the formation of the euro, altho it was rather silent about the systematic flaws of the whole design. But it also shows that the Germans were also culpable. It showed, for example, how countries like Germany and France deceived other members of the euro zone when they did not fulfil the requirements of the stability pact. They formed behind the scenes alliances with each other to avoid the sanctions. The German government even tried to persuade the Bundesbank to revalue their gold reserves in order to improve the fiscal position.

DiranMJuly 13th, 2012 at 2:59 pm

Living through this mess in Greece, I deeply appreciate your work on the subject. I have circulated your article – as I have in the past work of Nouriel and others like my friend Michael Pettis to various policy makers in Greece. It is terribly frustrating the local stubborness to face the music and deal with this mess in a rational fashion.

Panic has been the main mode here. The Greek middle class is terribly frightened to leave the Eurozone. The political elite cling to their privileges. For them to be well seen by Brussels is an important element in their careers. They have all staked their careers on this project. They are not suffering personally, It is mainly the little guy who is paying the price.

DiranMJuly 13th, 2012 at 2:59 pm

The June 17 elections illustrate how easily things can be manipulated in Greece. By threats of Eurozone expulsion and political polarization, the Greek political managed to re-establish a government with largely the same people in full control. The main opposition party SYRIZA is the refuge of many of the previous PASOK government have fled in hiding. Both swear their loyalty to Brussels, because they are very dependent on the transfer money.

It may well be that some other EZ countries depart before Greece like the Finns or the Italians. I fear that the final outcome in Greek way prove the worst possible with chaos and collapse.

anonJuly 13th, 2012 at 3:22 pm

The 90's had one very brief recession in which nominal GDP never even went negative. NGDP was 5%+ on average for the entire decade. Rather than make yourself look bad just admit you were wrong.

Also, your housing bubble "call" in 2000 was way off. The bubble hadn't even started then. Almost all of the house price appreciation occurred in the ensuing 6 years when prices went up 100% from where you made your great prediction.

This is just more evidence that you're a stopped clock who was finally right about something in 2008. You're always negative with nothing unique to contribute.

I don't get this guyJuly 13th, 2012 at 3:48 pm

anon, why do you have to be so offensive all the time? Why can't you just make comments and criticisms without all the pointless insults? Seriously, what is wrong with you?

Scott FullwilerJuly 13th, 2012 at 4:23 pm

Those examples hardly qualify as being "very wrong."

Wally's book was "Silent Depression" and was and still is a legitimate interpretation. Further, if you read Wray's work during that period, your characterization is just wrong. It's very clear that he described a strong economy by traditional measures–he called it the Clinton boom or something like that regularly–clouded by both rising financial fragility (whose "day of reckoning" was delayed by the transition to another bubble) and the fact that the rising tide didn't lift all boats (which was the title of one of his pieces, in fact).

Warren's Russian bet, as Randy says, lost on the politics, not the economics. Further, Warren was fully aware of the risks, calling the fund something like "the high risk Russian bond fund" or something like that. He points out that because he gave the fund a name that recognized the risks there were no investor lawsuits even given the losses.

MMT hackers are a dime a dozen, and their bias is completely transparent as they never get the story right.

LRWrayJuly 13th, 2012 at 4:41 pm

Hi Phil, Anon, Fido, Audited (all the same person, of course–we caught on to you, so it is sort of funny that you respond to support yourself): What matters is the analysis, not the date; I am neither a trader nor a forecaster. "Predictions" are contingent projections. The 2000 bubble call actually was correct; I think Dean Baker also called it about the same time. All the ducks were in a row for a real estate bubble.

TomJuly 13th, 2012 at 4:46 pm

Maybe you could try commenting on the present situation instead of selectively re-hashing the past in order to make yourself out as prophetic. Yaaaawn.

The euro's fundamental flaw is that it enables people to deplete a Eurozone member country of base money. Current account deficits are a minor problem compared to capital flight. This is something that hasn't happened since the gold standard. With modern national currencies that can't be redeemed, capital flight results in a sell-off by foreigners of the currency to locals, depressing the relative price of the country's financial assets and helping to alleviate capital flight. In the Eurozone, capital flight results in euros leaving to other parts of the Eurozone, and the country runs out of base money, in other words the banking system runs out of reserves. Hence international bailouts and central bank refinancing to re-inject euros into reserves-depleted periphery countries, but since the FX rate doesn't adjust and asset prices don't come down quickly enough, the capital flight keeps up relentlessly.

LRWrayJuly 13th, 2012 at 4:47 pm

Scott, right. And as I recall Warren had hedged the bets (as a good economist would do!) and the counterparty defaulted; Warren eventually one that in the courts so I'm not sure he actually lost anything in the end. I don't think the WashPost reporter had got the whole episode correctly–in any case I am sure that if anyone is really that interested, he/she can get it straight from Warren.

PJ PierreJuly 13th, 2012 at 6:28 pm

Warren Mosler turned over management to his partners around '96-'97. LTCM and the Russian default were after that.

Jose GuilhermeJuly 13th, 2012 at 7:41 pm

I didn't misunderstand at all.

Sound finance means no budget deficits, and no budget deficits means no "vertical" money creation.

On the other hand, if peripheral states try to issue bonds to support deficits, then markets will raise interest rates up to a point where their only recourse is exiting the bond markets and asking for European "help": send the euros in, so that the government can pay its bills.

The end point is the same in both cases: governments aren't able to create money, while commercial banks can go on as before, issuing loans and crediting deposit accounts, aka money.

Perhaps UMKC professors have now a unique chance to explain to European public opinion how the euro screwed the electorates while promoting banks to a level higher than national governments. In today's EMU money creation is a prerogative of the ECB and commercial banks. The generous European elite, however, will allow peoples to choose at the ballot box governments that may not even create money.

I guess this could be called European civilization promoting democracy to a higher level of refinement, never seen before.

Jose GuilhermeJuly 14th, 2012 at 12:03 am

Good point.

In the same line of reasoning, the Krugman/Obstfeld International Economics textbook, in its 1990s editions, presciently warned of this risk for the eurozone. It saw it, rightly, as an apllication the second best theorem (Lipsey/Lancaster, 1956).

The reasoning proceeds thus: the ideal situation is free movement for both capital and labor within the eurozone. They both exist in theory, but not in practice. When a asymmetrical shock hits, there is massive capital flight from the crisis-ridden periphery to the core, but labor cannot accompany this movement. So the periphery gets stuck, trapped in a situation of enormous unemployment and scarce capital.

See what's happening in Spain right now, and I'd call this prediction by Krugman and Obstfeld a fabulous hit.

Most American and British economists – both neo-classicals and post-keynesians – deserve recognition for having gotten it so right with their 1990s pessimism over the future of the eurozone.

Martin Wolf made this same point during a recent conference held, quite appropriately, in Lisbon. He said a high point in his career, of which he felt especially proud, was having contributed – however modestly – to keeping Britain out of the single currency.

Wow, no law suits after losing $800 million? I guess that means everything was A-ok!

Also, Wray is on record calling the 80's and 90's "sub-par" so your rewrite history are a lie:

"we do not attribute this prolonged period of subpar economic performance solely to misguided monetary policy, we do believe that the nearly single-minded pursuit of stable prices by the Federal Reserve since 1979 has contributed to the high levels of unemployment, low productivity growth, and reduced economic growth experienced by the U.S. economy during the 1980s and 1990s (when compared with the performance enjoyed between World War II and the early 1970s)." – Wray, 1993, just before the big boom

Scott FullwilerJuly 14th, 2012 at 3:24 am

Early 90s were quite bad, or at least sluggish. I've used to show a video from 1995 by Paul Solman where most everyone was thinking we were still in the recession from 1990-91. Many, many have argued that the 1973-early 1990s were down years. Lots of data to confirm that, Wally's book being one of the most comprehensive. Reagan "boom" wasn't that good–even good years there only as good as average of expansion/recession pre-1973.

Your Warren comments are stupid, move the goalposts, and don't warrant response. You're just a hater with an emotional stake in hating MMT. Nobody cares.

See virtually every previous LRW post, including those by "anon." Anyway, whether you like Godley or not, to be consistent, MMT as stopped clock critique applies to MMT critics pushing Godley, even if you don't.

Regarding Dean Baker, see link. I suppose he's a stopped clock, too, though.

Here's Warren @ http://moslereconomics.com/2012/02/14/dj-feds-plo…

"the ‘High Risk Opportunities Fund’ was, but I had turned over management to my partners at the end of 1997 due to a disagreement over the management of that fund. I insisted there was a substantial risk of default due to the fixed fx policy and administrators who didn’t understand their monetary system.

The only part of the fund I was responsible for was the name, which all involved still credit for the fact that there was not a single investor lawsuit. And I invested no money in it."

The central bank is a one club golfer. It has the power to purchase anything priced in its currency and it can do that for as long as it likes. Essentially it can swap something for currency until the cows come home.

That is the nuclear fission reaction at the core of a central bank.

How much power you get out of it then depends on the design and flexibility of the control rods in place to stop that power getting out of hand.

The UK has a very flexible system where essentially the Executive gets to tell the central bank what to do and when to do it. So we've got great control rods, but Homer Simpson operating them.

The US system is slightly less flexible since it has lots of separation built into the legislative framework.

Whereas the EMU has completely inflexible control rods that are near impossible to move from a near shutdown.

TARGET2 automatically replenishes reserves as required.

The issue with the banks is one of capital. Reserves are just assets like loans.

You can have a bank with 80% of its assets in liquid reserves and it can still be bust.

I would like to promote Jose Guilherme's insight / recommendation to default view of comments. It is completely true, it is the key question for people in general in the EMU, and afaIk has not been publicly said:

"Perhaps UMKC professors have now a unique chance to explain to European public opinion how the euro screwed the electorates while promoting banks to a level higher than national governments. In today's EMU money creation is a prerogative of the ECB and commercial banks. The generous European elite, however, will allow peoples to choose at the ballot box governments that may not even create money."

Prof. Wray — "Hi Phil, Anon, Fido, Audited…", et seq. Almost fell off my chair laughing.

I have found this recent interest in various blogs of who said what and when in the past to be very enlightening. I also like getting the true story of events.

I am seriously worried about the insane difficulty in getting people to see how our monetary system really works. You and your colleagues and those "on-board" have sure been trying your best to be heard. But I'm scared that the oppressed classes will erupt in violence if we don't change the conversation damn soon. (They already have in some places.) We have got to stop talking about how many keystrokes and spreadsheet entries we've got and start talking about what kind and amount of real resources we need to support those who are unable to support themselves adequately, humanely and sustainably.

Hehehe… I think you just evaded the housing bubble thing with your ad hominem garbage.

And yes, the US housing bubble started in the late-90s. As did the Irish bubble. (Both were running fiscal surpluses!).

It doesn't matter what you think about Baker (actually, I don't think it matters what you think of anyone because you're a vindictive idiot who doesn't publish comments under his real name) because Baker's data was good. You can see the uptick in US housing around 1997-98 versus the rental rate. The last time this had occurred in the US was during the housing bubble in the late 1970s.

Get a clue, dude. And publish under your real name if you're so confident in your garbage macroeconomic "analysis".

Hi Randall,

You mentioned i a recent post at NEP that you had previously responded to the balance-of-payments concerns and criticisms put forward by Ramanan. Do you have a link to any of your responses, or to any posts or papers which have dealt with those sorts of issues?

One questio he has raised recently is why Mexico turned to the IMF for a credit line following the rapid depreciation of the peso in 2009, despite the fact that Mexico issues its own floating currency. Any thoughts?

I look forward to the next installment, by the way.

Thanks.

@ Neil Wilson, who said:
"The issue with the banks is one of capital".

True in theory but not in practice.

Banks are always bailed out by sovereign entities once their capital is about to be wiped out by bad loan decisions. This has been demonstrated time and again since 2008 – and it will be demonstrated again as many times has needed.

Just look at what's recently happened in Spain where the banking sector is going to be bailed out, the Spanish state is excluded from the "aid" package and the population at large effectively pays the whole price via extra austerity.

So, the capital constraint is effectively absent from banking activity – a unique privilege indeed.

In the eurozone at least it is then really the case that:
Banks are free to create horizontal money – while governments are only free to act within the very real, not theoretical, constraints imposed on them by the ECB and the eurozone transnational institutions.

John: on the same page. However, the main barrier to progressives and others rallying around decent policy that you support is the AFFORDABILITY issue. They all believe we cannot afford it. Got to tax the rich, you know. And increase sales taxes to pay for local govt; and payroll taxes to pay for SocSec; and death taxes to pay for who knows what. So then the framing all turns to who should get taxed. We never get to any actual spending policy. Forget it. Keystrokes. Govt can afford to buy anything for sale. You want homes for the poor? Yes we can. Healthcare? Yes we can. Infrastructure? Yes we can. Keystrokes to put unemployed resources to work.

With all due respect, I think replying to Ramanan is a waste of time. Mexico? In the grips of the neoliberal agenda. They do all sorts of crazy things.

But watch next week for more on the BoP issue in Euroland.

RGDP growth has declined dramatically in the US over the past half century: 1960s RGDP growth was at about 5%, 1970s 4.5%, 1980s expansion 4%, 1990s 3.5%, 2000s 3%, currently about 2.5% since the beginning of the "expansion." Same trends with RGDP per capita.
