Yves right here. Your humble blogger believes that the bogosities of mainstream economics, which is sort of all of it, should be ridiculed early and sometimes. This Richard Murphy publish takes aside one financial canard, that of people as primarily being rational financial actors.

Neoclassical economics is constructed on myths — and none is extra absurd than the thought of homo Economicus: the peerlessly rational, absolutely knowledgeable, self-interested human who supposedly drives all financial decision-making.
However does such an individual exist? After all not. We’re emotional, social, biased, and unsure beings. We act from compassion, behavior, and worry as a lot as calculation. And but, this fantasy of rationality nonetheless shapes coverage, markets, and even how governments take into consideration human behaviour.
On this video, I dismantle this fantasy, which is on the coronary heart of mainstream economics, exhibiting how its assumptions about utility, good data, and revenue maximisation bear no resemblance to actuality and why that issues for the whole lot from monetary crises to on a regular basis life.
If we’re to construct an economics that serves folks, not concept, we should bury homo Economicus as soon as and for all and settle for that uncertainty, cooperation, and care outline actual human behaviour.
That is the transcript:
The world of neoclassical economics is constructed on myths, all of them assumptions that supposedly make that system of thought work, however that are in actual fact whole and utter garbage.
And none is extra essential than the thought of ‘ homo economicus’. That is the supposedly rational, completely knowledgeable, fully self-interested one who lives in our society and drives all financial motion.
Does ‘homo economicus’ exist? Are you that individual? Are you at all times rational? At all times fully knowledgeable about each determination you need to make? And at all times self-interested to the exclusion of all others? If not, then neoclassical economics has failed since you’ve not complied with the norm that it thinks that people actually adjust to.
The declare by neoclassical economics is that you just search to maximise your private utility. However no person is aware of what utility is. Financial utility is the quantity, supposedly, of satisfaction, happiness, or profit that you just obtain from consuming a superb or service. However there isn’t any approach for sure of measuring this as a result of it makes fairly clear that this isn’t about cash. However the device which all of economics makes use of to approximate utility is cash, creating a complete battle in itself.
And this concept of utility is completely subjective and summary, and but it’s what supposedly makes neoclassical economics work as a result of we, apparently, attempt to maximise our happiness, simply as neoclassical economics supposes that companies attempt to maximise their revenue, although there isn’t any accepted definition of what revenue is, and even when there was, maximising revenue requires sure data of the longer term, and none of us are possessed of it.
Nevertheless, neoclassical economics overcomes that drawback as a result of it assumes that data of the longer term is ideal and free, because of which all selections may be, supposedly, coldly calculated to maximise our well-being.
That is the whole and utter gibberish nonsense on which neoclassical economics is constructed.
Homo-economicus is actual, they declare, although you’ve by no means met anyone who’s vaguely just like the individual so described.
In actuality, in fact, we people should not have good data.
We’re pushed by feelings, bias and behavior.
We aren’t rational.
We’re caring, compassionate and emotional.
And we most undoubtedly have no idea the longer term. Nor can we at all times even know what’s greatest for our personal well-being, and but we nonetheless by some means make selections largely on the idea of heuristics and guidelines of thumb, as a result of more often than not we merely haven’t obtained the chance to sit down down and do the chilly laborious calculations to work out what would maximise our well-being, even when we knew what that regarded like.
So the consequence is that removed from us being particular person, atomised, separate entities, all of us making our personal rational selections, in follow, herd behaviour drives a whole lot of what we do, and we see the results throughout us. Booms and crashes are one of many apparent penalties which have a specific value.
So why can we faux that homo-economicus is current on this planet?
Why can we assume motives that don’t exist?
Why does neoclassical economics ignore the dangers that bubbles and instability arising from human and laptop behaviour create?
Economics merely does all this to make its personal reasonably small, petty world work. And within the meantime, it truly completely misreads how actual folks act and stay.
The consequence is throughout us. The foundations of neoclassical economics, which have gone on to tell neoliberal economics, lead to a unbroken disaster as a result of the coverage descriptions which are created by this mind-set don’t match with actuality.
If you advise on a world that doesn’t exist, and inform the world that does exist to attempt to develop into a world that isn’t solely not in existence, however which might by no means exist, then you’re certain to ship a prescription for failure. And that’s what we’ve got.
Homo-economicus, this supposedly rational individual, who’s on the epicentre of financial pondering – this totally commonplace single individual, from whom no person ever deviates in behaviour – needs to be put down. Painlessly, however nonetheless, put down. And we should presume they by no means existed as a result of, in fact, they haven’t.
If the world is to develop into a very sturdy, functioning place by which economics can play a invaluable position by embracing the uncertainty of life itself, then we’ve got to desert this assumption, which underpins neoclassical economics.
