Confidence or confidence trick in the eurozone?

At a meeting of eurozone finance ministers in February, Greece’s Yannis Stournaras asked a fairly straightforward question: Could the troika explain what, if any, impact the International Monetary Fund’s miscalculation of fiscal multipliers had on the Greek adjustment program?

The question came in the wake of the IMF admitting a few weeks earlier that it had underestimated the recessionary impact that rapid fiscal adjustment would have in the current negative economic climate. The IMF assumed the fiscal multiplier of spending cuts and tax hikes was around 0.5 percent of gross domestic product – in other words, austerity measures equivalent to 1 percent of GDP would produce a 0.5 percent decline in economic activity. Its economists, however, discovered that the real fiscal multiplier was between 0.9 and 1.7 percent of GDP.

In Greece, critics of the bailout saw this as evidence that its austerity formula should be consigned to the rubbish bin. They put considerable pressure on the government to respond to the IMF’s revelation. Fearful of what implications an admission that the program had been built on unsound foundations might have on public opinion, the coalition played down the Fund’s findings.

Bearing this in mind, Stournaras put a rather tame question to Greece’s lenders after admitting to journalists that he could draw no reliable conclusions from the new analysis on the fiscal multipliers provided by the IMF’s chief economist Olivier Blanchard.

The response to Stournaras’s low-key request was a full-on blast from European Economics and Monetary Affairs Commissioner Olli Rehn. So forceful was the response, in fact, that one had to wonder whether the level of protest suggested that Greece might have a serious case.

Rehn took the unusual step of writing a letter (http://ec.europa.eu/commission_2010-2014/rehn/documents/cab20130213_en.pdf) to all EU finance ministers. It was copied to the key troika players: Mario Draghi of the European Central Bank, Christine Lagarde of the IMF and Klaus Regling of the European Stability Mechanism. In his letter, Rehn referred to discussions about fiscal multipliers as “a debate that has not been helpful and has risked to erode the confidence that we have painstakingly built up over the past few years in numerous late-night meetings.”

Rehn suggested the IMF’s new findings on fiscal multipliers were inconsequential because their “robustness is limited” and “it cannot be excluded that other factors impacted on growth.” Just to press home the point, the EU commissioner argued that the study was “of particularly limited use when it comes to the specific case of Greece.”

All in all, Rehn said, the fiscal multipliers admission did not serve as a call to reverse “the fiscal police course followed during the crisis” and that “other factors should also be taken into account when determining the appropriate pace of fiscal consolidation for any single country.”

In summary, the European official claimed that Blanchard’s study was not relevant to the debate about how the crisis is being tackled because a) there are questions about how fiscal multipliers are calculated and b) other factors have to be taken into account.

However, Rehn went a step further and added another reason for the discussion over fiscal multipliers to be dismissed. He said that public debt in the EU needed to be tackled as it had risen by too much. “And it is widely acknowledged, based on serious academic research, that when public debt levels rise above 90 percent they tend to have a negative impact on economic dynamism, which translates into low growth for many years.”

The message was clear: It is not failed policies or austerity in the eurozone that is causing prolonged recession in many countries; it is the fact that public debt had risen to levels that strangled their economies and that measures needed to be taken to reduce this debt.

Although he didn’t mention it by name, the “serious academic research” Rehn cited was a 2010 paper written by Carmen Reinhart and Kenneth Rogoff called “Growth in a Time of Debt” (http://www.nber.org/papers/w15639). The two economists argued that historical analysis shows countries with debt-to-GDP ratios above 90 percent see their growth rates suffer. While the eurozone’s crisis policy has not been based on this paper alone, it is one of the academic studies that has been used to justify all-out efforts to reduce public debt as quickly as possible, even when other economists pointed out that this might be more destructive because it could cause deep and prolonged recessions.

This week, a new study from three economists at the University of Massachusetts has cast serious doubt on the pertinence of the Reinhart and Rogoff paper. Thomas Herndon, Michael Ash and Robert Pollin suggest that there are three serious flaws () with the research: There has been selective use of the data to leave out years of high debt and normal growth, the way countries are weighted is open to serious challenge, and five countries have been excluded frhttp://www.nextnewdeal.net/rortybomb/researchers-finally-replicated-reinhart-rogoff-and-there-are-serious-problemsom the study because of a coding error with the spreadsheet Reinhart and Rogoff used.

The two economists have admitted the Excel error but have attempted to defend themselves over the other two charges (http://blogs.ft.com/ftdata/2013/04/17/the-reinhart-rogoff-response-i/). Nevertheless, the weaknesses uncovered by their University of Massachusetts colleagues serve as another urgent call for the one-dimensional approach to the economic crisis in Europe to be reconsidered. “We are not suggesting that governments should be free to borrow and spend profligately,” wrote Pollin and Ash in the Financial Times (http://www.ft.com/intl/cms/s/0/9e5107f8-a75c-11e2-9fbe-00144feabdc0.html#axzz2Qo5jg9XH). “But government deficit spending, pursued judiciously, remains the single most effective tool we have to fight against mass unemployment caused by severe recessions.”

The doubts over the Reinhart and Rogoff study also bring into question the ease and confidence with which policymakers, such as Rehn, used it as intellectual justification for economic policy, especially in the face of doubts or strong criticism. Just as Blanchard’s findings on fiscal multipliers were not proof that austerity is a nonstarter, so Ash, Pollin and Herndon have not produced evidence that tackling high public debt is necessarily wrong. What both papers have done, though, is to press for a more urgent examination of the choices that are being made by eurozone officials and for it to be unacceptable for those in positions of authority to fob off critics.

As the FT’s Alphaville blog (http://ftalphaville.ft.com/2013/04/16/1463192/raining-on-reinhart-and-rogoff/) aptly put it: “The point is perhaps that it’s very tricky to boil things down into a pat policy conclusion in any case.” Here lies a serious problem for Rehn, though. He dismissed questions about fiscal multipliers because he said there were doubts about the calculations and because other factors were also at play. However, exactly the same thing has now been said about the Reinhart and Rogoff study which he cited in his response: Economists have shown that its methodology is questionable and its interpretation is far too narrow. Where does this leave the European commissioner’s assertion that the most vital issue to all this is not to damage “confidence”?

From fiscal multipliers to academic papers on debt, the number of unanswered questions about the basis on which Europe is forming its economic policy are mounting. Despite the European Parliament’s best efforts in recent weeks to question Rehn, Draghi and Eurogroup chief Jeroen Dijsselbloem about their major policy decisions, there have not been any satisfying answers. In fact, the whole process continues to desperately lack transparency and accountability. This can’t be sustainable, especially when fresh doubt has been created about the scientific and intellectual underpinnings of the current policy course. If it’s confidence we’re after, it’s worth keeping in mind that few things erode people’s trust as much as the feeling that they’re being hoodwinked.
