"why do people submit drafts that have already been posted on Arxiv to peer-reviewed journals then?"
This may be a cultural issue and it helps to know where the arXiv comes from.

In the discussion of Britain's EU exit initiated by Frank, Cyrille challenges me repeatedly on free movement of capital:
I think the "four freedoms" should apply as widely as possible so, on that basis, it would be a bad thing if the UK were to leave the EU.That is a consistent view, ...
[b]ut I had been under the impression that you were no fan of the free movement of capital -certainly an unrestricted one.
Unfettered cross-border capital flows are a bad idea. Just look at the financial crises of the last 30 years, worldwide.
So, do we want free movement of capital? More below the fold.

If you google EONIA heartbeat the top three hits are my own European Tribune blogs
and a Nordea research note from 16 July 2013, Liquidity draining & EUR short end
which has the following to say:
EONIA heartbeat pattern has returned...
Before December 2011, EONIA tended to spike on the last day of the maintenance period, as a result of fine tuning operations conducted by the ECB. These operations were suspended in the end of 2011 and the pattern wasn't seen any longer. Since the LTRO repayments started however, EONIA has spiked in the end of the month/quarter, and the largest spike in over a year occurred in the end of Q2 this year.
I don't think that the ECB fine-tuning operations were suspended. What happened was indeed that the LTROs flooded the banking sector with so much excess liquidity that banks no longer needed extra liquidity at the end of ECB reserve periods in order to meet their reserve requirements. But the weekly refinancing operations which the fine-tuning operations are part of still took place.

Beyond BRICS blog: Brazil: net debtor to the world (Jonathan Wheatley, January 15, 2014)
It has been a proud boast of Brasília for several years that it is a net creditor to the world because it holds more in foreign exchange reserves than it owes in overseas debt. However, it is far from clear that this is still the case. The issue is just one example of the vulnerabilities investors must include in their calculations of how Brazil and other emerging markets will fare as monetary policy in the developed world becomes less accommodating.
The gist of the argument is that the Brazilian Central Bank has been using currency swaps to try to drain domestic demand for dollars in an attempt to support its exchange rate. Analysts at BNP Paribas argue that the short sollar position accumulated by the BCB in the process must be subtracted from the foreign reserves, which now (after a few months of sliding Real exchange rate and increasing swap positions) means that Brazil is no longer a Dollar creditor.
Below I argue that this is wrong: Brazil remains a net creditor to the world since the swap positions with the domestic economy cannot affect the external balance (a point on which the BCB is correct). The conclusion I draw is that swaps is not a viable way to support the exchange rate. But we know a central bank cannot support its exchange rate indefinitely in any case. All this shows is that currency swaps with the domestic economy, however "clever", still cannot affect the exchange rate. You need to use reserves for that.

This week eurogreen started a thread about spaceflight and the discussion quickly took an interestellar turn. Naturally, relativistic spaceflight made an appearance along with the usual misconceptions and misunderstood heuristics. Special relativity is obviously unintuitive, and unfortunately there is no substitute for a little linear algebra if one wants a reality check for one's heuristics.
Here I will describe the main features of the simple-minded interstellar flight strategy of accelerating at the rate \(1g\) of Earth's gravity for the first half of the trip and decelerating for the second half.
No, this is not a picture of a relativistic spacecraft with a van-Allen-like cosmic ray shield

Three weeks ago I shared the following article: EXCLUSIVE: Syrians In Ghouta Claim Saudi-Supplied Rebels Behind Chemical Attack (By Dale Gavlak and Yahya Ababneh, MintPress News, August 29, 2013)
Dale Gavlak assisted in the research and writing process of this article, but was not on the ground in Syria. Reporter Yahya Ababneh, with whom the report was written in collaboration, was the correspondent on the ground in Ghouta who spoke directly with the rebels, their family members, victims of the chemical weapons attacks and local residents.
Gavlak is a MintPress News Middle East correspondent who has been freelancing for the AP as a Amman, Jordan correspondent for nearly a decade. This report is not an Associated Press article; rather it is exclusive to MintPress News.
I am quoting only the byline because this has now become a point of controversy in itself.
Antiwar.com: Retraction and Apology to Our Readers for Mint Press Article on Syria Gas Attack (Eric Garris, September 20, 2013)
On August 31, Antiwar.com reprinted an article from Mint Press News: "Syrians In Ghouta Claim Saudi-Supplied Rebels Behind Chemical Attack." We originally linked to it, but then reprinted on our site at the request of Mint Press because traffic on their site was crashing their server. The validity of the story was primarily based on the fact that the supposed co-author (Dale Gavlak) is a reporter for Associated Press.
Dale Gavlak has issued a statement saying she did not co-author the article and denies that she traveled to Syria or contributed to the article in any way. Here is his statement:
Mint Press News incorrectly used my byline for an article it published on August 29, 2013 alleging chemical weapons usage by Syrian rebels. Despite my repeated requests, made directly and through legal counsel, they have not been willing to issue a retraction stating that I was not the author. Yahya Ababneh is the sole reporter and author of the Mint Press News piece. To date, Mint Press News has refused to act professionally or honestly in regards to disclosing the actual authorship and sources for this story.
I did not travel to Syria, have any discussions with Syrian rebels, or do any other reporting on which the article is based. The article is not based on my personal observations and should not be given credence based on my journalistic reputation. Also, it is false and misleading to attribute comments made in the story as if they were my own statements.
Gavlak has apparently sent an identically worded email
to Brown Moses
, a prominent blogger.

In his fifth and final column on the economic programme of the major German parties for the upcoming elections, Wolfgang Münchau has this to say about Die Linke: Wahlprogramm der Linken: Rot-Rot-Grün ist die beste Lösung für Europa (Spiegel, 28.08.2013)
Das Wahlprogramm der Linken in puncto Euro-Krise zeugt von Ehrlichkeit und Intelligenz. Damit ist die Partei den Großen weit voraus - und der ideale Partner für SPD und Grüne.Election program of The Left: Red-Red-Green is the best solution for Europe
The Election program of the Left shows, on the Euro crisis, honestly and intelligence. Thus the party is far ahead of the big parties, and the ideal partner of the SPD and Greens.
Going beyond the Euro crisis analysis, which is standard around here, Münchau discusses the international dimension of redistributive policies. Quote and translation below the fold.

From our very own Chris Cook: Iran at the crossroads (Trend, 9 July 2013)
... today's high oil prices have not only acted to deter consumption, but have enabled Iran to act against unsustainable energy subsidies and pin the blame for an unpopular policy firmly on the US and EU. Iran's far-sighted strategic decision to process Iranian oil and gas into petrochemicals is now bearing fruit, since it keeps in Iran value previously extracted by the country's oil buyers, and transcends sanctions on crude oil.
... being ejected from the international SWIFT bank payment system meant that Iranians would necessarily have to use their renowned ingenuity to do something else. I also pointed out that the inability to access Swiss hard currency bank accounts would deter anyone tempted to take advantage of an official position.
In my view, even if Iran is tempted through negotiations to go back down the Western financial road, the toxic combination of partisan US politics and external relationships are such that financial sanctions are to all intents and purposes irreversible, at least in relation to the dollar.

I got to thinking about the rhetoric of monetary austerity and There-Is-No-Alternative, and I remembered the following oft-repeated argument by Thomas:
It annoys me that I keep having to point this out, but if the environmental movement is seen to stand for - to advocate- mass poverty, it will loose all popular support, and die a highly deserved death. This entire line of thinking is a dead end, because if it is mistaken - and I am quite confident it is - it is Evil, in exactly the same way austerity is Evil, and if correct we are in any case doomed, because the course of action that would imply will never ever happen.
Austerity is evil. Austerians (and first among them, Merkel and Schäuble) continuously promise decades of recession and mass poverty. But it doesn't seem to be losing popular support; or if it is, it's losing popular support more slowly than the opposition. The "opinion leaders" in the media are not attacking Austerity with this kind of argument that voluntary poverty is unacceptable as they would be if those in power were "back to the land" environmentalists.
So, if Austerity™ "will lose all popular support and die a highly deserved death", why is it not happening? Does it happen "in the long run", when we're all dead anyway?

We just had a discussion of whether the Central European floods of the past week are an indication of a change in climate regime or not. A particular bone of contention was Jeff Masters' throwaway remark (quoted by ATinNM) that
If it seems like getting two 1-in-100 to 1-in-500 year floods in eleven years is a bit suspicious--well, it is. Those recurrence intervals are based on weather statistics from Earth's former climate. We are now in a new climate regime ...
One difficulty here is that the meaning of "100-year flood" seems to be unintuitive. As I explained in the thread:
the correct way to think about this is as the probability of the waiting time. Thus, "two events in 11 years" means "one waiting time of 11 years" so we're talking about just one observation, not two. The first flood resets the clock, so to speak. If we knew the date of the previous "100-year flood" in Central Europe, we'd have two observations to compare with the 100-year average waiting time.
ARGeezer, however, puts his finger on a key methodological issue:
I was originally thinking about the appropriateness of the designation of a certain level of flood as a 'hundred year event' and how that designation was achieved. Was it that no such event had been seen for 100 years, that the known frequency of such events was 100 years or was it simply assigning a designation in the face of knowing that the historical record is sketchy.
The fact is that detailed river flow statistics only exist for about 100 years, often less, and are extrapolated to larger flood sizes using theoretical probability distributions. In a 1994 paper [PDF]
for the Geological Society of America, Donald Turcotte wrote
For large floods the fractal predictions (F) correlates best with the log Gumbel (LGu), while the other statistical techniques predict longer recurrence time for very serious floods. The fractal and log Gumbel are essentially power-law correlations, whereas the others are essentially logarithmic. The Log Pearson type III (LP) is the Federally-approved distribution for evaluating the flood hazard in the United States. For station I-1805 the 100 year flood predicted by the fractal correlation is a factor of 1.6 greater than the 100 year flood predicted by the Log Pearson type III correlation. For station 11-0980 the 100-year flood predicted by the fractal correlation is a factor of 2.3 times greater than the 100 year flood predicted by the log Pearson type III correlation. If, in fact, fractal statistics are applicable, then the use of log Pearson type III statistics consistently underestimates the severity of the 100, 150 and 200 year floods.
With the fit parameters given by Turcotte, "under the fractal model" the 100-year flood sizes given by the "Federally aproved" model are actually 40-year floods. Further evidence in favour of self-similar distributions over the log-Pearson type III is given, for instance, in this 2006 paper
(only abstract available). The immediate question is whether the Europeans are making the same model assumption as the Americans and thus the so-called "100-year floods" are actually 40-year floods, in which case to have two of them in 11 years is not really that shocking.
Below the fold, some more wonk on recurrence time statistics.

This is what a currency peg to the Euro does to an economy on the fringes of the EU: The Economic Winter Will Stay in Croatia (6 May 2013)
Quite pessimistically is titled the spring forecast of the European Commission for Croatia - "Recovery slipping further away. Stuck in recession". Only two months before its accession to EU, the moods in Croatia are not at all festive. The economy has been in recession since 2008 as by now the economic activity has shrunk by almost 12%. The first signs of recovery are expected in 2014, but the conditionality is huge. In 2013, the Croatian economy is expected to contract by 1% as the main hamper to growth still is domestic demand which will continue to decline. The main reasons are continuing growth of unemployment as well as the nominal cuts of public sector wages by 3%. Inflation, too, is a factor for the not good economic perspectives ahead of the future 28th EU member state.
What? The Commission doesn't think cutting public sector wages in a recession is a good idea? Someone should tell Portugal!

From everyone's favourite sorry excuse for a historian: An Unqualified Apology (05/04/2013)
During a recent question-and-answer session at a conference in California, I made comments about John Maynard Keynes that were as stupid as they were insensitive.
I had been asked to comment on Keynes's famous observation "In the long run we are all dead." The point I had made in my presentation was that in the long run our children, grandchildren and great-grandchildren are alive, and will have to deal with the consequences of our economic actions.
But I should not have suggested - in an off-the-cuff response that was not part of my presentation - that Keynes was indifferent to the long run because he had no children, nor that he had no children because he was gay. This was doubly stupid. First, it is obvious that people who do not have children also care about future generations. Second, I had forgotten that Keynes's wife Lydia miscarried.
Niall Ferguson omits the third and important way his comments were stupid: he should not have suggested that Keynes advocated deficit spending when the economy is far from full employment because he was indifferent to the long run.

I have an analysis piece up on Eurointelligence: thoughts on banking union and the Cyprus 'solution' (28.03.2013)
"The central bank defends the payment system every day, every hour, every minute." Scott Fullwiler calls this "the fundamental truth of central bank operations" and I will call it the essence of monetary union.
In sum, the case seems compelling for a Eurozone-wide clearing system, liquidity provision, deposit insurance, banking regulation and supervision, and a special resolution scheme for banks. The case is underpinned by the necessity to provide a unified and efficient payments system for the currency area, and the need to ensure its safety and defend its integrity. Arguments against joint supervision hinder the Central bank in distinguishing between illiquid and insolvent institutions. Polemics against joint deposit insurance actually foster cross-border deposit runs. And rhetoric against Target2 undermines the integrity of the payments and clearing system itself.
In conclusion, even if an immediate bank run due to Cyprus is avoided in the rest of the Eurozone, will all of Draghi's horses and all of Draghi's men be able to put together the broken egg of public confidence in deposit insurance, and more generally in the Eurozone's commitment to the integrity of its payments system?

Reuters: EU in "denial" that sick economy costs lives, health experts say (March 27, 2013)
"There is a clear problem of denial of the health effects of the crisis, even though they are very apparent," said lead researcher Martin McKee of the European Observatory on Health Systems and Policies, a group backed by the World Health Organisation.
"The European Commission has a treaty obligation to look at the health effect of all of its policies but has not produced any impact assessment on the health effects of the austerity measures imposed by the troika."
Despite a devastating financial crisis, Iceland rejected austerity, following a referendum, and instead continued to invest in its social welfare system. As a result, the researchers found there had been no discernible effects on health since the crisis.
Iceland's economy has now returned to growth, but the recovery is patchy and inflation has remained stubbornly high.

This has been a great week for Turkey. I won't say 'let me explain' because it explains itself:
Jerusalem Post: 'Syria crisis necessitated Turkey apology' (03/24/2013)
Netanyahu says fear that Damascus's chemical weapons will fall into the hands of terror organizations led to apology.
Take that, Avigdor Lieberman
Then there was the Persian new year announcement:
Hurriyet: Leader of PKK in northern Iraq declares cease-fire (March/23/2013)
The jailed leader of the PKK in Turkey, Abdullah Öcalan, declared a cease-fire in a message conveyed during Nevruz festivities in Diyarbakır on March 21, to hundreds of thousands people. He also called on armed militants to withdraw from Turkish soil, indicating that these moves would mark a milestone for "a new era" and herald the building of a "new Turkey."
And the European Union's handling of Cyprus presents an opportunity for Turkey to advance its interests there, too.

One of the all-time greatest political quotations comes from the Italian novel Il Gattopardo: everything needs to change, so everything can stay the same. And the result of the Italian election indicates that the 20-year process of change initiated with Tangentopoli and Mani Pulite is coming to a close, leaving everything as it was before.

A correspondent sends me notice of the latest paper by Jean Pisani-Ferry of the Bruegel think tank: The known unknowns and the unknown unknowns of the EMU (26th October 2012). There is even a related video on the Bruegel website!
Bruegel, as some people may remember, is hardly my favourite think tank...
And given that Jean Pisani-Ferry and his Bruegel think tank live off reinforcing the Eurocracy conventional wisdom, I am actually pleasantly surprised to find the following paragraph in there:
The second reason has to do with what the Maastricht treaty did not include, ie the prevention of non-fiscal imbalances. When thinking about possible threats that EMU should be defended against, policymakers in Maastricht looked back at past experience and identified two: inflation and fiscal laxity. Financial instability was at the time perceived as being of minor importance and, even though currency unification was expected to reinforce financial integration, no provision was envisaged to deal with the effects of private credit booms-and-busts. EMU was conceived as an economic and monetary union, not as a financial union. True, the EU could have relied on the Broad Economic Policy Guidelines (BEPGs), a catch-all procedure rooted in the treaty, but it was in fact a weak, non-binding and rather neglected procedure. This view proved to be short-sighted. While public indebtedness in the southern countries remained broadly stable or even declined during the first decade of EMU, private indebtedness financed by capital inflows skyrocketed, resulting in the previously described massive macroeconomic divergence.
Which basically means that the Eurozone policy response and the crisis diagnosis itself have been terribly flawed for 4 years and continue to be flawed. Not one of the Eurozone's policy developments purported to respond to the crisis would have made a difference to the private financial sector dynamics of the past 10 years had they been in place from the start.

Sunday, 21 October, saw two simultaneous regional elections, in Galicia and in the Basque Country. The main result has been a collapse of the PSOE regional parties, conceding a larger absolute majority to the PP in Galicia, and second place in the Basque Country to EH-Bildu, the successor party of the ETA sympathiser parties that were illegal for the past decade, until ETA gave up a year ago.
