Australian Economists Predictions No Better Than Flipping a Coin

Australia 290

First time accepted submitter ras writes "The Reserve Bank of Australia did some investigation into the accuracy of their economic predictions — the ones they use to run the country — with less than flattering results. '70 per cent of the RBA's forecasts for underlying inflation for the year ahead were close to the mark, but its predictions of economic growth were less accurate, and its unemployment rate estimates no better than [chance] ... The Reserve Bank employs numbers of people on very high pay and what they're admitting now is that their — all of this so-called science — has produced nothing more than what a roll of the dice could produce.'"

Your underpants stains are showing.

They're trying to predict weather. Climate in economics is much more predictable -- there is a strong correlation between economic freedom and wellbeing of the average citizen. Goobers like you don't realize that a "safety net" serves to take the rough edges off this economic powerhouse, instead fancying it is the only thing good that's going on.

If you were actually interested in statistically solid and demonstrated economic models instead of fantasy worlds in your mind that "work" the same way 2 + 2 = 7 works in the mind of a young child, instead of looking at the normal, i.e. failboat east-west political axis, you would at least look at the highly predictive axis of economic freedom, with good protection of property rights on one end and lack of protection, be it from anarchy or warlord or mafia or out of control socoalism on the other.

You believe in a religion, sir. This is why it seems magical and unpredictable to you. I've described the formula, the theory, which successfully makes predictions as to wellbeing and advancement.

I further predict you will ignore it. That's two
successful predictions about you and your economic religion.

That's not what Keynesian economists tell us. Though this is what Austrian economists tell us. Funny that the majority of the world runs on Keynesian economics and is suffering badly for it.

A major part of the problem is that the thing that macro-economists study, the economy of the world, changes its behavior in response to the reported observations of the economists. Though the problem happens to some extent with other sciences (from physics to biology to sociology), it's at its most extreme in economics due to the massive incentives for behavioral screwing around. (Micro-economics has fewer problems because the incentives for gaming it are so much smaller.)

The other part of the problem (and your strawman) is that there are several major models for how macro-economics should work, notably the Keynesian models and the Friedmanite models. They give radically different predictions, but they're just models and that's a fact that people often lose sight of. Like all models, they have particular domains of applicability (and different models have different domains!) and are poor reflections of reality. Their weaknesses are also their strength, as they allow the model to be tractable enough to make predictions with them, but they are just models. People tend to lose sight of that basic fact.

So while the right thing to do is to use a model, you've got to keep in mind that the model might be totally wrong in the current situation: if the models predictions don't align with reality, you must change which model you use. That's the scientific approach. Pity the various zealots don't grasp that...

A major part of the problem is that the thing that macro-economists study, the economy of the world, changes its behavior in response to the reported observations of the economists.

It's worse than that, at least according to Austrian economics. For them, the theoretical basis of macro-economics, or at least of almost all of them, namely, the assumption what money (as a measurement unit) is what matters, is simply false. So, all the models starting from it will suffer no matter what.

The main criticism Austrian economists throw at macro-economics, econometrics etc. is that money isn't an objective unit, it's just a representation of subjective preferences that very from person to person, and within a single person from instant to instant, only resembling something minimally solid, and thus as a fake unit, as a kind of surface effect. Thus, the same way that a sociology divorced of any concept of human psychology is bogus, so is any macro-economics that doesn't base itself entirely on that small subset of human psychology that is micro-economics. True economics is at best a sub-field of psychology, and macro economics is at most a sub-field of sociology.

Austrian economists only do math after they manages to understood reasonably well the psychological mechanisms behind a set of atomic exchanges (not necessarily involving money), provided it shows itself as something that can have calculations done, which most often than not isn't the case.

Mainstream economics doesn't like this, at all. Keynesians, marxists, econometrists etc. all believe they have a unit of measurement, and that they can turn this unit and its measurement into a hard science. They cannot. It's wishful thinking, if not outright bullshit. But it's a bullshit so full of technobabble, so enchanting in its seeming seriousness, that the self-deception simply proceeds, unchecked.

Now, that doesn't means Austrian economics isn't full of bullshit too. It's own model of human psychology they call praxeology is extremely flawed, since it's based on philosophical assumptions more than on actual psychological research. Much of it is quite useful, or at least inspiring, but non-scientific anyway. But what they do very well, and the reason I keep reading them, is their debunking of mainstream economics pseudoscientific assumptions. They are at the top of their game when they take a macro-economics equation, break it down in its main components, and proceed to show analytically how what it describes is pure, glorified nonsense.

So, here's what must be done to really turn economics into the mostly scientific discipline it can ever be: take Austrian criticism of macro-economics, add the state of the art in cognitive sciences, develop an actually valid psychology-based micro-economics from both (it won't be Austrian's praxeology), and then, by way of reductionist thinking, build from then, step by step and floor-by-floor, a bottom-up macro-economics that's based on something actually relevant and universally valid (which "money" most definitely isn't).

Then, and only then, at least a semblance of actually working models.

Uh, general relativity and anything else in physics is just a model, too.
The difference is that physicist have the brains to realize that when their "model" is more than marginally and very rarely wrong you don't have a model, you're just making shit up.
So no, the problem is not that they are "just models", but that what economists use just aren't models in any useful meaning of the word.

You do know the economy that the RBA was looking after had a big Keynesian pump prime at the beginning of the GFC and never went into recession? You know, basically that big smoking crater almost every economy fell into? That's where China and Australia didnt go - and a lot of that thanks to good ol fashioned Keynsian spending.

And as a result came out of it looking a hell of a lot better while austerity (Austrian economics) shat on any number of countries from a great height?

Austrian economics mostly says that people should stop playing with shit they don't understand in the first place (hayekian 'pretense of knowledge'), so they don't have to fix results of their own mistakes, potentially making even more mistakes in the process.
Interest rates are a price signal, you can't just lower them for political gains or whatever and not expect the economy to implode few years down the road when malinvestment levels are simply too high to contain. Is the structural defficiency of the global economy fixed? No, not in the slightest. All i see is balooning sovereign debts and balance sheets of central banks, a recovery concentrated in stock markets. In other words the can got kicked down the road once again.

Umm, so what's the Keynesian excuse for Japan's "Lost Decade" and more recently, America's non-recovery from the it's-all-Bush's-fault recession?

Lots of Keynesian goodness showered on both economies with nothing but massive government debt to show for it.

As for the observation that economics isn't a science, the complete indifference to the scientific method should have made that obvious. The delightful irony is that when the scientific method's applied to the field of economics, the hypothesis being that economics is a science by virtue of its predictive powers, the hypothesis fails.

Re:Economy is not a science. (5, Insightful)

The Evil Atheist (2484676) | about a year and a half ago | (#42784385)

Nothing about the US bailouts was Keynesian. It may look Keynesian, but the underlying motive and effect is US Crazy Randian. What is Keynesian about tax cuts for the rich and attacking the middle class?

As for Japan, it actually isn't that bad. Unlike what economists would like us to believe, perpetual economic growth is stupid and dangerous. Japan kept it mostly level and it wouldn't have been so bad if economists weren't fear mongering about phantoms. Japan may have lost a decade, but it's not as if it plunged into the Dark Ages.

This is the stupid reality economists have people like you believing - that you can live in a city and not die from common diseases, not go hungry, not go homeless, but if you don't have your five wide screen TVs in your McMansion with economic growth every year, then it's the Worst Economy Ever.

You are being extremely ignorant of the Australian situation and really are just parroting the government spin. The reason we didn't go into a recession had nothing to do with the government spend. Australia was one of the few countries with extremely strict banking regulations which meant banks could not leverage themselves in the fashion they did in Europe and the US and hence no initial funding crisis, secondly as much as our banks suck they don't use the ridiculous sub prime lending practises that the US practised and thirdly our economy was massively supported by the mining industry shipping ore at record prices to China. What the government did was purely a PR compaign.

Re:Economy is not a science. (1)

You're being ignorant. The Austrian school (and the Chicago school alike) asserts that economics is totally scientific and permeated by incontrovertible laws and that laissez-faire rent-seeking is the only 'system' that is in accordance with their very selective results from carefully culled data put through functions that 'prove' their 'point'. The Chicago school is the worst of these; the Austrian and Keynesian schools are little better.

They're all little different. In summary, they're all shit and assert that they know the Secret Science of Economy, and that their own particular variation of finance-fueled markets is the only escape from imminent ruin or enslavement.

Keynesianism is barely being used anywhere at the moment. We're in the middle of a major recession and most countries are cutting back spending. Some are even deciding that now is the right time to pay back their debts.

In addition, Keynesianism is both a set of prescriptions and a general model for how the economy should behave. In the latter case, the model has, actually, done an astonishingly good job of predicting the behavior of the economy during this recession.

Nah, this is simply the effect of mobilizing massive amounts of natural resources (the mining.) This is the same basic thing that kept the soviet union up for so long, of course in that case it was state sponsored but the how and why isnt really relevant to the effect.

The problem is that you are just exporting most of the resources. You are getting some instant cash now, but you arent creating any value at all. This is similar to a company that is in trouble selling all its inventory at cost in order to get some much needed operating capital.

Worse than that, not only is it not real science (it's a guide for sound behaviour, there are certain true statements that can be made about economics [slashdot.org] ), but the so called 'mainstream economists' try to confuse you even about actual sciences, like math, so they don't want you even looking at real numbers [slashdot.org] .

The fake mainstream 'economists' are political hacks, they just want to keep clinging to power [slashdot.org] , so that's what they promote - power, and printing [slashdot.org] money [slashdot.org] is a huge [slashdot.org] power.

The fake "mainstream economists" justify government position on printing money to expand its power [slashdot.org] , and then to cover up the inevitable outcome of this behaviour, they shift the blame to the private sector, hitting it with various regulations whose aim is to hide [slashdot.org] the facts, the truth about inflation.

Of-course gov't also uses other means to grow itself, income taxes [slashdot.org] , regulations (which are also taxes, when you are regulated and forced to comply, be it a license you have to buy or whatever you have to do to comply, it's a tax). People who attempt to fight the government on the fact that for example income tax is illegal [slashdot.org] end up destroyed [slashdot.org] by the system.

In the meanwhile other consequences of this monetary destruction show up as market gambling [slashdot.org] based on lack of normal yield [slashdot.org] (as an example)

Of-course the problem is that the eventual the day of reckoning seems to never come, but the reason is that having a 'reserve currency' status pushes it much further into the future [slashdot.org] than what would normally happen with a country in that position [slashdot.org] .

But there is huge damage that is done to the minds of the people, their understanding of simple economics, they become so confused [slashdot.org] , they have no idea what is happening. They just feel that something is wrong, but they can't figure it out, all because of the 'mainstream economists' confusing the shit out of them. These people themselves are not blameless, they are the reason that the government is able to do this damage on the large scale, giving the gov't the tools by voting for politicians who promise [slashdot.org] policies that are extremely [slashdot.org] damaging [slashdot.org] to the economics in the long term [slashdot.org] , all being justified as 'social fairness [slashdot.org] '.

Unfortunately all branches of government are no so cooperative that they simply end up rubber-stamping [slashdot.org] whatever the next violation of individual freedom that comes out of the legislative offices.

Meanwhile people who are taxed more and more [slashdot.org] to pay for the unsustainable gov't spending end up leaving to be freer somewhere else [slashdot.org] (and paying less taxes = more freedom, people don't seem to understand what freedom is anymore).

I don't agree. Non-science includes things such as making up theories with no way of validating them, or denying evidence logically incompatible with the theory.

But nothing in the scientific method precludes studying a complex field displaying chaotic behaviour. Sure, it's not a walk in the park, and extrapolating results in an evolving society is probably not the safest bet. IMHO, that's where the problem is - you need some kind of safe guard or way of interpreting how realistic the predictions are, and it needs to be easy to understand, not some statistical mumbojumbo.

I've always liked the pattern matching/machine learning computer science way of thinking about this - set apart part of the data set for validation, build an explicit prediction model, train it and you get some easy-to-interpret results like "23% were predicted incorrectly, here's how they look like/are distributed". There's no "under these assumptions which we don't know to which degree hold, there's a number that should be below 5 according to a statistics professor speaking in a general context for the results to be valid".

No this is a common misconception. Investing in the stock market is much riskier that normal gambling because the probability distributions are not so well behaved. Generally risk is hidden in the stock market for a long time, and the odds of any event occuring are impossible to estimate without huge errors, whereas when you gamble generally the odds are quite well known and follow a normal distribution. You can work out exactly how much you will lose on average though normal gambling.

That's not to say that all of the establishment is unaware of the pitfalls: many distingushed scholars, like Daniel Kahneman, Nassim Taleb and others, preach the right gospel about our inability to evaluate economic forecasts correctly. Karl Otto Pöhl, the ex president of the German Bundesbank, was once quoted as saying, in response on a question on the future movement of the Dollar-Dmark exchange rate: " the central bank does not make forecasts, and above all not on the future." This is obviously a witticism, but it betrays a keen awareness of the pitfalls of economics as a forecasting tool. The variables are too many, non linearity is the norm, and if you have to utter the phrase "all else being equal", you can throw all the other words to the dogs.
The push to try to forecast the economy, tough, does not come in reality from the instinctive need of humanity to dispel uncertainty: it comes from governments who have to justify dirigistic policies, Tax incentives etc. It's quite hard to impose for example a carbon tax, if the honest answer to the (legitimate) question if it will be a drag or a push on the economy is: "How in hell would I know?"

Estimates of Uncertainty around the RBA's Forecasts
Abstract:

We use past forecast errors to construct confidence intervals and other estimates of uncertainty around the Reserve Bank of Australia's forecasts of key macroeconomic variables. Our estimates suggest that uncertainty about forecasts is high. We find that the RBA's forecasts have substantial explanatory power for the inflation rate but not for GDP growth.

That is completely unfair. Weathermen are right at least half of the time. I mean, the worst weathermen I've ever known of were right half of the time. Good weathermen are right almost all of the time. Decent weathermen are right more than 3/4 of the time. Those people who ONLY REMEMBER when the weathermen were wrong tend to give weathermen a bad name. Despite that, they are mostly right.

Economists? I've never met one, never even heard of one that I trust. Bunch of self important douches, running about, selling the common man on pyramid schemes, ponzi schemes, etc ad nauseum. Screw them all - they belong in prison. Right after we shoot all the lawyers, we'll take care of that little detail.

Now weather.gov, they're pretty damn accurate. It's the local news station that's shit.

The problem seems to come from each station wanting to be able to report that they were the first to warn you about some major storm. Thus, if NOAA predicts an inch of snow, all of the television weatherman predict up to 12 inches. They're much more concerned about failing to predict a storm than they are about incorrectly predicting one when one does not occur.

Even NOAA is a little bad about this. They often show half of the days of the week with the "rainy" icon, just because there's a 50% chance of rain, which kind of neglects the fact that when there's a 50% chance of rain, then if there's any rain at all, it isn't likely to be much. It doesn't make sense since the day is going to be much more like a non-rainy day than a rainy day. Thankfully, though, once you realize this, their reports are actually pretty damn accurate.

Ok, you already modded down to -1, but you know what, you did interesting claim I'm interested to answer to. Because it is example how lot of people have gotten their history fastfood in their veins - and ignorance and fear about subjects they don't really understand constructs their world view.

Marx was wierd, true. He was also harsh and cruel in his words (he was sort of armchair anti-nationalist and racist a little bit too), however time he lived in was also harsh and cruel (And Europe has lived trough series of series of devastating wars), so it must be taken into account. Dismissing his work on *trying* to understand human nature trough economics, and why capitalism rules the world as "communist/socialist propaganda" is very hollow. But taking in mind for how long Socialism was painted as big evil of "rightful Western", it's actually no surprise.

He got lot of things right, mostly describing why capitalism works they way it works. Also lot of people dismiss his future predictions as failure of Bolsheviks. There's one huge gap in their knowledge though - Marx predicted, that Socialism will become reality when industrialization and modernization driven by Capitalism greed will remove need for working. Sounds familiar, no? It's not precise prediction, it may even fail, but it gives you food for thought.

What usually people don't know that Socialists split at the beginning of last century - Bolsheviks (as from Russian "majority" or "more than others", t.i. referring to bigger supporter base) rejected reaching required modernization levels driven by greed as basis of Capitalism and stated that they will impose their dictatorship as they claimed that they know how to reach ideal Socialism, and then there was Social democrats, who wanted to work within democratic system (still in it's infancy at that time), as they followed more Marx vision and were against bloodshed - which followed October Revolution (although I would dispute Red Terror as something exceptional - Russia was land of cruel at that time, and Red Terror and White Terror fed each other quite nicely, driven by revenge and fear). Historically, Russia was full of people in despair and almost slave level industrialization made life very miserable, so while Bolsheviks used iron fist to crush dissidents, they had mass appeal, because they promised to solve problems right now.

So essentially Marx did understand economics and (a little bit of) human nature - well, at least for his century anyway. For me he's not a hero, nor villain. He is just a man, who really tried to think about problem we dismiss or even try to understand, because it's so uncomfortable to think or talk about.

Fake economics (1, Interesting)

udachny (2454394) | about a year and a half ago | (#42784227)

The entire mainstream industry of the so called "mainstream" economics is fake.

Realise that what economics really is, it's very simple. In reality there isn't actually a need for economists. In the beginning of the 20th century there were maybe 10 people who actually were known as economists, today there are tens of thousands. Why is that and what is it that they do? How is being an 'economist' more important or useful than being say an accountant?

An accountant can be very useful to a company, he really can find ways to make things more efficient, find ways to structure the business in a way that reduces costs. Unfortunately the government forces companies, people not only to pay income taxes (which is the most terrible tax, the most destructive tax you can think of for an economy, you get less of what you tax, you get more of what you subsidise, so if you tax people's work, you get less of it, if you subsidise people not working, you'll get more of that) to be unpaid IRS agents.

In 1942 the government forced employers to start withholding employee's income taxes, and that added more work for an employer, it costs money to do that kind of work. Of-course the government doesn't have a problem adding costs to activities that other people have to incur, but really, you have to be crazy to want to invest and employ people in most of the Western countries today. So accountants can help companies to reduce taxes for example.

What have economists done for the businesses and for people though? Have the economists helped people? As I said, in the beginning of the 20th century USA had maybe 10 economists. The economy of USA was growing, the 19th century was time of slight deflation (prices were slightly falling all the time, the dollar was strengthening, yet more and more productive capacity was added, people invested. USA became largest manufacturer, exporter and creditor nation). Of-course there are tens of thousands of 'economists' today and today USA is the largest in the world and in history of the world debtor nation, with 40-50 Billion USD / month trade deficits, with largest in the world and in history funded debt, unfunded debt, various contingency liabilities.

People like Krugman are suggesting dropping the pretence of solvency and just starting to print 1Trillion dollar coins, etc.

Greenspan was known for this 'Greenspan Put' over the nineties, when his policies of inflation fuelled the stock market bubble and started the housing and the bond bubble. Bernanke is known as the "Helicopter Ben".

None of these people saw the stock market and the housing market bubbles being inflated, none of them understand the biggest gov't credit bubble being inflated right now (bond and USD bubble, really it's the government bubble). Bernanke didn't know the US housing was in a bubble while the bubble was actually bursting already. These 'economists'.

In the meanwhile people who just follow the fundamental principles (normal economics, known as 'Austrian' school, but really it is just common sense economics), people like John Paulson, Peter Schiff, Jim Rogers, Marc Faber, they made millions and more because they just followed the fundamentals.

The fundamentals are: you can't spend more than you earn. Earning = working = selling things in the real market that people want to buy. Economy = production, it does not equal consumption. Consumption is just a trivial consequence of production, without production nothing can be consumed. Production comes first. Production comes out of investments. Investments come out of savings. Savings come out of the difference between some over-production and under-consumption.

Money cannot be printed, printing money is inflation. Printing money does not make more products. Real money IS products. Fiat currency is not real money if it's not backed by anything. Fiat = currency that is mandated by gov't to be accepted, currency by decree.

Real money imposes lending and spending discipline. Fake money (fiat that is printed by gov't) destroys that discipline.

People who fail in their businesses need to be let to fail, they must not be propped up by gov't taking from the productive. The failures will fail anyway, the longer you keep them alive artificially, the bigger will be the eventual failure.

Investment comes from savings, and this is the real credit, credit cannot be pulled out of nothing. Credit that is pulled out of nothing causes inflation, destruction of real purchasing power, eventually rising prices.

Nobody can tell you where the prices will rise exactly as you create more and more inflation, the prices will rise somewhere, this will become the next bubble and it will burst eventually.

If you keep pumping more and more currency or money into a bubble that is bursting, you can keep it up, but you will be destroying ability of the economy to recover.

Debts need to be restructured (eliminated), this will be done either honestly (restructuring, taking a haircut) or dishonestly (inflation). Politicians most of the time (almost always) choose inflation, because that is politically expedient.

Whatever the 'mainstream' economics are, is most likely the wrong thing. As Samuel Clemens said: " Whenever you find that you are on the side of the majority, it is time to reform."

Economics is not an actual science, it's just a guide for sound behaviour. The so called "mainstream economists" want to keep their jobs, want to feel important, so they cling to the power structure that exists, giving it the justification that it wants. Politicians want to print money an thus the whoever ends up agreeing with the politicians and justifying their behaviour becomes known as the "mainstream economist". Whatever the majority of people think they study and understand about economics, especially money and inflation in universities is actually political propaganda.

Whatever in fact you think is the right thing for your household economically is actually what is the right thing for the country. When you have tough economic times you need to find ways to cut spending and if possible to grow your earnings, well the same exact thing applies to nations.

The so called "mainstream economists" exist to confuse you, don't buy any of it. When they tell you that "inflation is good and deflation is bad", don't buy it.

Whatever government sells you as their "economic statistics" is designed for your consumption, it's not real. The inflation levels gov't says exist are not real, they are much higher. The GDP is not real, especially because it's not deflated by a proper inflation number.

An inflated bubble needs to be allowed to deflate, people need to be allowed to fail, companies, businesses, governments need to be allowed to restructure, to shrink in size, to fail, to release the scarce resources so that the debts that cannot be paid are wiped out one way or another, and the best way to wipe them out is not by destroying the currency but by defaulting and restructuring. This allows the economy to rebuild much faster than what happens after the currency gets destroyed.

Bad money drives good money out. People don't want to take bad money, they expect good money. Learn a bit about "Gresham's law"

Learn from people [wikipedia.org] who do understand [youtube.com] the economy enough [blogspot.de] to make money [gloomboomdoom.com] in the economic system where majority ends up losing money.

I think it makes much more sense to look at people who actually make money and learn from them rather than ever bothering with people who never show this ability but have degrees that are subsidised by the system, that are rewarded in this system with positions of high profile, high power and supposed respect, while not helping anybody in actuality except for the politicians to keep their own power.

Here's the one about the Australian economist (2)

dbIII (701233) | about a year and a half ago | (#42784237)

A while back a leading Australian economist was going increase profits in the wool industry by driving the price up. He suggested killing a lot of sheep to make it happen. People listened and there was a massive continent wide cull. Even after that the price didn't change.
He'd forgotten about cotton.

Yes, it really did happen.

The problem isn't so much with economics itself since any understanding of that one way or another was really irrelevant to career prospects as a leading economist, it was instead all about political connections and being a mouth for hire.

Re:Here's the one about the Australian economist (0)

Anonymous Coward | about a year and a half ago | (#42784365)

culling as you call it of Australian sheep had nothing to do with some economist and everything to do with Natural market conditions. If you think farmers listen to some economist as to what to do with their stock then I have a bridge to sell you. When prices are depressed stock becomes too expensive to keep and has a relatively low sale price, the net result is the stock is sent to the abattoir, not because they are trying to cull, but because that is where to get some of the money back to keep the farms running.

THE RISE AND FALL OF CATASTROPHE THEORY APPLICATIONS IN ECONOMICS: WAS THE BABY THROWN OUT WITH THE BATHWATER?

Quote from the introduction: "The science writer, John Horgan (1995, 1997), has ridiculed what he labels “chaoplexology,” a combination of chaos theory and complexity theory. A central charge against this alleged monstrosity is that it, or more precisely its two component parts separately, are (or were) fads, intellectual bubbles of little consequence. They would soon disappear and deservedly so, once scholars and intellects realized what worthless dross they truly were (or are). As the culminating centerpiece of his argument, Horgan introduced the label, “the four C’s,” which consist of cybernetics, catastrophe theory, chaos theory, and complexity theory." (emphasis mine)
