Yves right here. Your humble blogger believes that the bogosities of mainstream economics, which is sort of all of it, have to be ridiculed early and infrequently. This Richard Murphy submit 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 concept of homo Economicus: the superbly rational, totally 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 fable, which is on the coronary heart of mainstream economics, displaying how its assumptions about utility, excellent data, and revenue maximisation bear no resemblance to actuality and why that issues for every part from monetary crises to on a regular basis life.
If we’re to construct an economics that serves folks, not principle, 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 truth complete and utter garbage.
And none is extra vital than the concept 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 particular person? Are you at all times rational? All the time fully knowledgeable about each determination it’s important 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 simply 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 simply obtain from consuming or service. However there isn’t any means 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, though 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 entire and utter gibberish nonsense on which neoclassical economics is constructed.
Homo-economicus is actual, they declare, though you’ve by no means met anyone who’s vaguely just like the particular person so described.
In actuality, in fact, we people do not need excellent data.
We’re pushed by feelings, bias and behavior.
We aren’t rational.
We’re caring, compassionate and emotional.
And we most positively have no idea the longer term. Nor can we at all times even know what’s finest for our personal well-being, and but we nonetheless one way or the other make selections largely on the idea of heuristics and guidelines of thumb, as a result of more often than not we merely haven’t acquired 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 seemed like.
So the consequence is that removed from us being particular person, atomised, separate entities, all of us making our personal rational selections, in observe, herd behaviour drives plenty of what we do, and we see the implications throughout us. Booms and crashes are one of many apparent penalties which have a selected price.
So why can we faux that homo-economicus is current on the earth?
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 quite small, petty world work. And within the meantime, it truly completely misreads how actual folks act and reside.
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 change into a world that’s not solely not in existence, however which might by no means exist, then you might be certain to ship a prescription for failure. And that’s what we have now.
Homo-economicus, this supposedly rational particular person, who’s on the epicentre of financial considering – this positively customary single particular person, 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 change into a extremely robust, functioning place by which economics can play a precious position by embracing the uncertainty of life itself, then we have now to desert this assumption, which underpins neoclassical economics.
