Excel Error Contributes To Problems With Austerity Study
quarterbuck writes "Many politicians, especially in Europe, have used the idea that economic growth is impeded by debt levels above 90% of GDP to justify austerity measures. The academic justification came from a paper and a book by Kenneth Rogoff and Carmen Reinhart. Now researchers at U Mass at Amherst have refuted the study — they find that not only was the data tainted by bad statistics, it also had an Excel error. Apparently when averaging a few GDP numbers in an excel sheet, they did not drag down the cell ranges down properly, excluding Belgium. The supporting website for the book, 'This time it is different,' has lots of financial information if a reader might want to replicate some of the results."
The Excel error is making the rounds as the cause of the problems with the study, but it's actually a minor component. The study also ignores some post-WWII data for countries that had a high debt load and high growth, and there's some fishy weighting going on: "The U.K. has 19 years (1946-1964) above 90 percent debt-to-GDP with an average 2.4 percent growth rate. New Zealand has one year in their sample above 90 percent debt-to-GDP with a growth rate of -7.6. These two numbers, 2.4 and -7.6 percent, are given equal weight in the final calculation, as they average the countries equally. Even though there are 19 times as many data points for the U.K."
No, finite resources do.
When I read the title, I expected a calculation or rounding issue, or an internal range issue from built in components and not "dumb ass user didn't set the range correctly when averaging". That's not an Excel error, that's a user error - Excel did exactly what it was told to do.
Anyone who prefers debt is a fucking idiot and shouldn't be trusted.
That statement is plain daft. It's much too broad. Sometimes debt can be good. For example, getting a mortgage for a home might not be bad. Sure, it would be better to buy with cash and avoid paying all the interest, but if you don't have a pile of cash lying around, you are limited to saving while paying rent. It might actually work out better to get the mortgage.
Also, getting a loan to start a company might be a great way to have enough capital to get to the market quickly and by doing so make a huge profit.
Not all debt is bad. Debt without any plan to pay it off and without evaluating whether the costs of managing the debt outweigh the benefits is bad. The problem is that most political parties these days seem to have a horizon of the next election when it comes to balancing the books. The problem with this sort of debt is that they spend up big and have no real plan to pay it back.

It's about what you spend it on.
If you spend it on capital goods that allow you to produce more, that's investment.
If you spend it on final use goods, that's consumption
Simple concepts: consumption is not production and not all spending is investment. And yet, look at how Gross Domestic Product is calculated.
GDP = private consumption + gross investment + government spending + (exports - imports)
Set your phasers on "funky"!
Attempting to justify more theft of the public and increased government spending.
It's simple to answer this question, do you want to incur debt or spend money that you have? Anyone who prefers debt is a fucking idiot and shouldn't be trusted.
Wow this brings stupidity to new levels. A report is widely used to justify government cut backs. The report proves to have mistakes in it that would have given a different result - so pointing out the error is "Statist Bullshit"? There would be some justification in arguing that the report does not matter, though for people who previously used it to argue their case this would be hypocritical. But to argue that we should continue to use the incorrect report because correcting it is statist is just dumb.
Does High Public Debt Consistently Stifle Economic Growth?
No, finite resources do.
High public debt drains away valuable resources faster than low public debt
Given the same amount of initial resource, a country with high public debt will have smaller chances for recovery
But then again, most economies (other than that of North Korea) are dynamic, and the amount of resource fluctuates

These two numbers, 2.4 and -7.6 percent, are given equal weight in the final calculation, as they average the countries equally. Even though there are 19 times as many data points for the U.K."
Why should the UK be given more weight? There's only one such country, not 19 such countries. And the UK data in question is highly correlated (it all comes from the same debt over the same span of time, not 19 different points in the UK's history).
In addition, the rebuttal ignores two stretches of data:
RR examines three data samples: 20 advanced economies over 1946{2009; the same 20 economies over roughly 200 years; and 20 emerging market economies 1970{2009. We repli- cate the results only from the first sample as these are the most relevant to current U.S. and European policy debates, and they require the least splicing of data from multiple sources. We focus exclusively on their results regarding means because these have generated the most widespread attention. On their website, Reinhart and Rogo provide public access to coun- try historical data for public debt and GDP growth in spreadsheets with complete source documentation.3 However, the spreadsheets do not include guidance on the exact data series, years, and methods used in RR.
It's worth noting here that the rebuttal is willing to take data from the period just after the Second World War where a number of countries had high debt and were transitioning from a total war economy (that is, an economy totally focused on winning a particular war to exclusion of everything else, including economic growth) to a normal one - including the 19 year series of the UK mentioned above, and periods of excluded (excluded that is from the original study for unknown reasons) data from Australia, New Zealand, and Canada. All of these incidentally show high economic growth combined with high debt.
If we're excluding data series due to their irrelevance to current economies, why should these be counted? The US and Europe haven't been in a total war economy since the end of the Second World War. So it is to be expected that one would not see the economic gain (whether or not the debt is present) that one saw in the immediate post-war period.
The original research seems weak for a number of reasons, but I'm not willing to call it "fishy" on the basis of a rebuttal which makes its own "fishy" assumptions.
The only real resources that fluctuate are labor and renewables
I guess you are not in the high tech field
As one in the tech field since the 1970's, one very real resource that I count on is BRAIN-POWER, aka, ideas
Timber can cut into wood for burning, or could be turned into tables and chair by carpenters, or could be used for building a dormitory, or, in the hands of master crafter like Stradivarius, becomes his world famous violins
Muchas Gracias, Señor Edward Snowden !
You know that Germany has relatively low unemployment compared to the rest of Europe because many youth learn trades instead of being jobless? Same for Austria and Switzerland.
Austerity affects everyone. It kill opportunities, it stifles social mobility, it removes funds from research and long term investments. There are no good aspects to austerity, except that at the top you fall less than those at the bottom so you are comparatively better off. But to rejoice in that makes you a horrible person.
You are entitled opinions, but not facts.
Not much I can add, except that maybe people who use the term, "Libertards" seem universally to be idiots. But that's just an entitled opinion of mine.
At some point the country with more debt has had more money than the other one. What matters is what the country is doing with that extra-resource. As a example, in June 1999, Google was 25 millions in debt, a considerably worst shape than my local kebab place.
Debt is just an indicator. That's what's wrong with the current austerity measure in Europe. It does not matter what a Country is doing with its money, Europe only cares about the yearly balance sheet and does not give a damn about the future of the country.
The UK has had much higher debt ratios in the past. It equalled 30 years of tax revenue after the war with France and Spain in the early 19th century. It took most of the century to pay it off
So? That was the UK's greatest period of growth and relative prosperity. It's often cited as an example of debt not impeding growth. Similarly the US had federal debt of 125%/GDP after WWII, and post-WWII was our greatest growth period. It helped that the debt was mostly internal (i.e. War Bonds were held by Americans, so paying off the debt meant paying Americans). AFAIK the same was true of the UK after the Napoleonic wars.
However, I'm not saying debt isn't important, just that it's not the only or the ultimate evil. Other things can be worse, and can justify increasing the debt.
