But there were economists that publicly predicted the burst of the housing bubble and resulting banking collapse... these economists just didnt work for banks because, surprise, banks weren't interested in that sort of information being made public and certainly werent interested in acting in a responsible manner regarding it. The banks certainly werent the ones to get the short end of the stick in the end.
These predictions werent in a single camp either. Both major schools of thought, the Austrians and Keynesians, were predicting it. The thing to keep in mind is that while the Austrians and Keynesians disagree on quite a few abstract things, that there are still fundamental economic premises that they all agree on.
The correct observation is not that it wasn't predicted.. its that so few even in the private sector paid any attention to the predictions.
Its no surprise that the American government didnt pay any attention, even though some members of the government were trying for years to do something about it. Too many in the government are corruptively self-interested -- trading legislation for donations and support -- for there to have been something meaningful done about it. Members of government such as Barney Frank (among many many others in both Republican and Democrat parties) absolutely denied that a housing bubble existed when opposing legislation to do something about it.
One poster on slashdot suggested that those from the Austrian school stick their fingers in their ears and go "nah nah nah nah I can't hear you" but in actuality it was the government and banks that did that, not economists from any school.

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.

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.

I think you're joking, but if not, "Austrian" is the name of a school of economic thinking. It's called that because, different from Marxism (from Marx's name), Keynesianism (from Keynes') etc., it had more than a single founding economist, and most of them where from Austria. I guess it could be named "Bawerkism" from its very first economist (Eugen von Bohm-Bawerk), but that's not how it went. Besides, although Bohm-Bawerk was the first, the most famous were Ludwig von Mises and Friefrich von Hayek, so that you do find people talking about "Misesian" and "Hayekian" when focusing on particular ideas from either. So, we're stuck with calling it "Austrian Economics". What, admittedly, is a source of confusion.
Re:Eh mate? (Score:5, Insightful)
The roots of Austrian economics begin with Carl Menger, not Bohm-Bawerk.
You're right, thanks.
From your other note, if Austrian economics is non-scientific then mathematics is also non-scientific. IMO (as an economist and not a philosopher) Austrian econ can make an even stronger case than than math for being scientific because I'm satisfied that the action axiom is a priori true whereas the fundamental axioms of math are not. You can probably deduce that I don't believe 'science' is defined by induction :-)
The problem with this line of reasoning is that it confuses two meaning of "science". Since you mention math, let me use it as an example.
Nowadays it's an accepted matter that you can select basically any set of axioms you wish, and from those you'll be able to fully develop an entire math from them. So, if I want, I can, let's say, determine that the division by 0 has a finite result, and as long as I follow rigorous a logical reasoning, I'll get a consistent, with-division-by-0 math. Some other things will work differently from what we're used, but that's about it.
Now, for us to go from math as a whole, which includes the set of all possible combinations of all possible arbitrarily chosen non-contradictory axioms, to that specific subset that applies to the real world and in turn can be used to describe it, we need a non-a priori component, in that we must observe the actual world and find what of those axioms apply here.
Praxeology doesn't do that for its own axioms. It defines with extreme precision what it understands by "action", and derive lots of conclusions from it, which for the sake of argument we can assume are valid. But it doesn't come and actually prove empirically that what specific thing it calls "action" is the only one at play in economic relations. So, since we're assuming the conclusions from the axiom, if 100% of economics is built upon "action", then praxeology describes all of economics. But this hasn't been proven. It could be that the actual number is 99.999%, or 50%, or 0.001%, or even that the percentage varies given changing factors.
Thus, even with praxeology being valid from one extreme to the other, we still need to actually look into the world to find how much of it actually applies. There's no way around it.
Additionally, the logic upon which deductions from the action axiom are obtained can itself be challenged. It's for the most part classic logic with Kantian additions. What does happen if we were to start deducing with, let's say, para-consistent logic instead? Would it work better or worse in the real world? This, too, is a matter that can only be solved with experimentation.
And so on and so forth. Nothing in this is as straightforward as Austrian economists make it to be.

Marx was wierd, true.

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.

Its because these studies are cherry picked all the way through.. they dont select investors randomly.. they select "top performers" which in their interpretation equates to "extreme risk takers" -- they dont select the guys that have brought in 8%/year average over 20 years.. they select the guy that brought in 150%/year over 2 years.

so? Mood and perception play as big (if not bigger) role as fundamentals do.
It's hard to nail recessions perfectly because as soon as the guys at the central smell approaching contraction they try to immediately paper it over, even with the coordinated help of their colleagues from other countries, so on the surface everything is peachy. Most of the time they manage to push the problem away, at least for some time.

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.

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.

My bank balance says otherwise. Then again, I invest in companies, not in the market.
When you go in without knowing a thing about the underlying companies or industries you end up relying on technical analysis or gimmicks like this [onlineinvestingai.com] which as far as I can tell is one magic crystal away from invoking sacred geometry to make market predictions. To paraphrase Robert Anton Wilson: Given a small enough chart and a blunt enough pencil any collection of points can be made to fit into a meaningful pattern.

everything is high stakes gambling. I've been married 21 years, all because I kissed a girl in front of her house. I finished my university the year the Italian government liberalized, after fifteen years, investing abroad, and I knew English, So I was hired as a fund manager. Economy is no different, except the collective feels a need to substitute something for "insufficient data", a noble tradition that continues on olden day shamanism. The big difference is that economist do not pierce their noses with animal bones, no matter how we'd like to perform that operation for them.
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?"
Re: (Score:3)
however, I disagree on one point: because greed and the propensity to violence exist, governments must be dirigiste to a degree if there is to be a stable society. Since economics is not much use for forecasting the effects of policy, they should forget economics and concentrate on policies

Economics - Simple Vs Complex system modelling (Score:4, Interesting)
Wonder if the RBA will now start listening more to one of Australia's most forward thinking economists, Dr Steve Keen [wikipedia.org]. Surprisingly, the vast majority of economist model "the economic system" based on simple linear assumptions. Steve Keen is trying to change all that by modelling the economy for what it is: a complex system. (See this short intro video) [youtube.com]. It is amazing the amount of flak he gets for applying complex system modelling techniques to the world of economics... (see some of his arguments with Krugman)
Here is a link to a presentation [debtdeflation.com] Dr Keen gave to google, interesting stuff.
