The error was the IMF attempting to keep Greece in the Eurozone rather than having them go bankrupt.Who Is Defending Austerity Now?
The Excel error heard 'round the world has deficit-cutters backpedaling
Austerity has been a policy in search of a justification ever since it began in 2010. Back then, policymakers decided it was time for policy to go back to "normal" even though the economy hadn't, because deficits just felt too big. The only thing they needed was a theory telling them why what they were doing made sense. Of course, this wasn't easy when unemployment was still high, and interest rates couldn't go any lower. Alberto Alesina and Silvia Ardagna took the first stab at it, arguing that reducing deficits would increase confidence and growth in the short-run. But this had the defect of being demonstrably untrue (in addition to being based off a naïve reading of the data). Countries that tried to aggressively cut their deficits amidst their slumps didn't recover; they fell into even deeper slumps.
Enter Carmen Reinhart and Ken Rogoff. They gave austerity a new raison d'être by shifting the debate from the short-to-the-long-run. Reinhart and Rogoff acknowledged austerity would hurt today, but said it would help tomorrow -- if it keeps governments from racking up debt of 90 percent of GDP, at which point growth supposedly slows dramatically. Now, this result was never more than just a correlation -- slow growth more likely causes high debt than the reverse -- but that didn't stop policymakers from imputing totemic significance to it. That is, it became a "fact" that everybody who mattered knew was true.
Except it wasn't. Reinhart and Rogoff goofed. They accidentally excluded some data in one case, and used some wrong data in another; the former because of an Excel snafu. If you correct for these very basic errors, their correlation gets even weaker, and the growth tipping point at 90 percent of GDP disappears. In other words, there's no there there anymore.
Austerity is back to being a policy without a justification.
If you think a bankrupt Greece would not have to make disastrous cuts than you are naive.
The flaw with your article is assuming a bankrupt country will still have someone who will loan them money to keep operational. Who would that be?
