Economics is a poitical onstraint.

As I keep pointing out, the models don't work because they don't have to. They exist as propaganda for decisions that benefit one tiny caste at the expense of all other castes.

There's nothing more complicated happening here.

See e.g. Spain, Greece Ireland, etc.

Or are you seriously going to argue that the decisions being made are somehow genuinely for the benefit of the majority of the population?

Re: Seed comment (none / 0)

Economics is a form of policy discourse. Whether it is a constraint or not, or honest or not, depends on context.

Re: Seed comment (4.00 / 3)

Can a policy discourse be scientific unless it models reality accurately?

Er - no.

So any pretence at science when a discourse has been repeatedly falsified is clearly dishonest.

As for constraints - as I said, ask the Spanish, the Greeks, the Irish, and the German workers if they feel their rights to a reasonable livelihood and a lack of nonsensical financial drama are being politically constrained.

If that's not clear enough, I'll put it more bluntly - economics as used in contemporary statecraft is simply a barefaced lie used by one class to justify the theft of time, creativity and resources from the other classes.

It has no scientific or empirical basis whatsoever. It's simply a blunt stick used to beat working people and bring them to heel for nakedly self-interested political reasons that have no connection whatsoever with their immediate or future prosperity or welfare.

And if the working people ever work this out, they're going to be really, really angry.

Re: Seed comment (3.00 / 2)

Social science is not "science." Rather it uses scientific methods to organize thinking, so that participants in its discourse can keep track of the veracity of claims, warrants, and reasoning being made. It is a way of improving the honesty of political discourse precisely because it allows a method for pointing out when people are lying or mistaken about things. It does this through forcing arguments into falsifiable hypotheses that allow for evidence to be presented.

Scientific methods are naturally very limited in policy discourse because so many of the parameters that matter most for deciding things in social life are unobservable by their nature, such as values, aesthetics, and the meaning of life -- the things which Ludwig Wittgenstein famously said that science must remain silent about.

Even by this standard neoclassical economics is unfit for purpose, because it intentionally obfuscates when people are lying or mistaken about things, and systematically refuses to acknowledge when its falsifiable hypotheses are falsified.

Really existing neoclassical economics is a systematically dishonest enterprise.

Re: Seed comment (none / 0)

I don't see any systematic attempt to obfuscate or refuse to acknowledge when hypotheses have been proven false. The papers and the data to check them are all there for everyone to see after all.

Rather, I do see an unfortunately high number of idiosyncratic cases where individual economists refuse to admit when their hypotheses have been proven lacking, but there is nothing in the methods themselves which cause this. If there was a problem with the methods, it could be labeled systematic, but this is a case of individual faults, not system faults, and it is prevalent in all social sciences. The heavy use of math in economics is what allows us to point it out more easily in economics, which is exactly how it should be and why math is so useful in economics.

You can get equilibrium-based macroeconomic models published in purportedly respectable journals.

It has been a full century since the Walrasian approach to economics was conclusively demonstrated to be intellectually and practically sterile. Persisting in promulgating it is systemic obfuscation and refusal to acknowledge falsification.

Rather, I do see an unfortunately high number of idiosyncratic cases where individual economists refuse to admit when their hypotheses have been proven lacking, but there is nothing in the methods themselves which cause this. If there was a problem with the methods, it could be labeled systematic, but this is a case of individual faults, not system faults,

The fact that falsification of economic equilibrium, model-consistent expectations, Say's Postulate, loanable funds, long-run money neutrality (and indeed the whole of the neoclassical long run) is not assimilated by the peer review process is a systemic fault, and a systemic dishonesty.

Publishing things you know or should know are nonsense is not honest just because it is possible for outside observes to take the time to dismantle the farrago of lies. In fact, this particular dishonest tactic has a name: The Gish Gallop.

Re: Seed comment (none / 1)

things which Ludwig Wittgenstein famously said that science must remain silent about.

Wittgenstein wasn't talking about science, he was talking about philosophy.

Wittgenstein to neoclassical economics: just just up.

Then again, famously Piero Sraffa managed to change Wittgenstein's mind about language and logic.

Re: Seed comment (none / 0)

Wittgenstein was talking about philosophy in the most general sense, including natural philosophy, i.e., science, and its uniquely helpful language for making and warranting truth proposition statements -- mathematics. Specifically he argued, and remained convinced for the most part, that the most important parts of questions about morality and God, like aesthetics, were not amenable to truth proposition language because truth proposition statements about such matters were nonsensical. (E.g., "Does beauty exist?" is a nonsensical question.) While the language of math and the methods of science might be illuminating (and they might be confounding as well), they can never be decisive in determining truth from falsehood in such matters, so the implication for economics and other social sciences is that, unlike in the natural sciences, you can't rely on mathematical models and observation alone to make what are essentially moral arguments. The sin of the neoclassical approach is that its practitioners too often use math to claim they have discovered right from wrong, when such a use of mathematical language is nonsensical.

Re: Seed comment (none / 0)

On the other hand, I'm just now finishing reading Keynes' treatise on probability and it's a wonderful development of the idea that probability is a branch of logic... And of course he does apply it to moral philosophy (haven't read that bit yet).

Did you actually work through all the math? I decided that it probably wasn't worth the effort to figure out a nonstandard notation that I'd never see anywhere else. Was I wrong?

Well, he uses

x|h

for the usual

P(x|h)

I've been skipping most of the algebra anyway, the book is more about the philosophy of probability as far as I'm concerned.

But I like reading historical works. The book could be written in half the length today - you could delete an entire chapter just by saying "probabilities are partially ordered".

I haven't given much thought to what his non-numerical probabilities are, that are in < and > relations with numerical probabilities nonetheless...

Quite.

And power. Especially power. Except when it becomes visible after people stop believing the lies about it.

Incidentally, there are scientific theories of personal and social values and aesthetics, with falsifiable premises.

(But I wouldn't expect someone who works on the management board of a bank to know that.)

Oh - and did you just attempt to imply that economics is about the meaning the life?

Really? How interesting.

Re: Seed comment (none / 1)

Yes, economics is, first and foremost, a branch of moral philosophy, which, unlike natural philosophy -- science -- which attempts to describe what can be observed about the world, moral philosophy is ultimately about discerning the meaning of life and its implications for how to create a just society.

Re: Seed comment (4.00 / 3)

Actually economics is equally dishonest when it pretends to be a branch of moral philosophy.

Firstly, moral philosophy is only tangentially related to meaning. The only honest position on the meaning of life is that no one knows and it's impossible to know in principle. Anyone who claims otherwise is lying.

So morality becomes a political and utilitarian issue - which it always is.

But you cannot go from there to claiming that economics - which even at its broadest is about one small subset of all possible human relationships - can ever provide a complete moral picture.

In practice of course economics claims to be moral - as in discussions of moral hazard, etc.

But in fact it's simply political misdirection. It attempts to frame the discussion of human relations in one specific way, while denying validity to other kinds of human relation.

The concept of 'rational self-interest' is immensely poisonous. It's also easily falsifiable behaviourally.

Non-sociopaths relate to others with mutuality and reciprocity. As a moral theory, economics has no useful concept of either.

So where is your morality now?

Re: Seed comment (none / 1)

Nothing in economics, whether it's Marxian, neoclassical, or whatever other approach, denies the validity of other kinds of human relations. Rather, economics is the study of the material aspects of human society, which is a very important part of the overall question of the meaning of life of how to go about creating a just society. Mutuality, reciprocity and rational self interest are entirely consistent concepts.

Re: Seed comment (4.00 / 3)

And naturally you will have no trouble pointing to the many examples of the IMF, the ECB, of the dictators installed and propped by Wall St, and of the entire financial industry using their fine understanding of mutuality and reciprocity to better the lives of working populations across the world.

A revised and empirical version of economics might - one day - be a useful tool for equitable democracy.

Currently it's nothing of the sort, in much the same way that a black widow spider bite isn't a good cure for indigestion.

Pretending that it is is dishonest and utterly shameful.

Right. Just like I won't have any trouble finding moral failings in the history of Roman Catholic Church or any other school of thought dealing with the study of morality, social justice, and the meaning of life.

Some of those schools of thought have useful and relevant things to contribute to society.

The insights of neo-classical economics which are both true and interesting can be counted on one hand. With fingers left over.

that's the pols' job, to explain patiently to the plebes how up is down and black is white.

damned if they don't pull it off surprisingly effectively, but rather than just lauding their talents for deviance, we need to take responsibility for our part in the bargain.

exactly how, remains the existential question...

i foresee 'unforeseen events' will play an increasingly decisive role in guiding change, since we seem transparently incapable of doing so under our own tutelage, proactively.
