Externalities: how economics is divorced from reality

Economists might have created for themselves an artificial air of impenetrable intellectualism, but the hoary old concept of externalities is one of the primary means by which the discipline has divorced itself from reality.

Unfortunately, for the rest of us, this has major consequences for the quality of our lives and our children’s future.

Allowing economists to divorce themselves from reality has two main consequences.

Firstly, it has allowed economists to explain away – and often completely ignore – glaring disparities and injustices. The use of externalities in economic theory is a convenient way of avoiding the attribution of costs that businesses, corporations and governments don’t want to pay or account for.

 

No accountability

In this way, ‘externalities’ provide a convenient theoretical tool that removes the need for political and social accountability.

Secondly, the use of externalities has allowed long-term costs – such as those associated with rampant climate change, for instance – to be excluded from most, if not all, price signals.

In other words, what we pay for goods and services does not include the costs of items classed as externalities, such as negative, generalised impacts on human health, or environmental exploitation and, especially, resource depletion.

Thanks to ‘externalities’, for instance, economists can tell us that we can drill for, extract and burn oil indefinitely, without any negative economic or environmental consequences.

 

Political expediency

Talking more theoretically, the use of externalities has enabled businesses, and especially corporations, to avoid the full costs of deploying human and natural capital. And, if ignored, these costs can rise without anyone noticing until, at some point, they become overwhelming. Humanity’s environmental debt is a prime example.

Despite its appearance of academic rigour and independence, the economics profession has helped to neutralise public discussion of otherwise controversial value judgements and political demands. By hiding these costs as ‘externalities’, the economics discipline has lent academic respectability to acts of theft and gross dishonesty.

Peter a journalist with 30 years experience of freelance writing, UK national newspaper and magazine production roles, and business development. In 2007, he developed and launched a mainstream-style green consumer magazine in the UK, called GreenerLiving, as a means of promoting sustainable change ‘within the system’. GreenerLiving closed during the post-crash recession, but Peter went on to become managing editor of the international ethical business title, Ethical Performance. However, Peter felt that the CSR sector has not succeeded in changing corporate priorities anywhere near fast enough, and so I decided to leave the treadmill of corporate employment and debt accumulation to focus on my own projects. Now poorer but a billion million times happier, he writes on political, economic and social issues – usually seriously, but sometimes as satire. He's currently writing Psychopath Economics, a book about the logic of social and economic power, belief systems, and the rise and fall of societies. Peter is convinced that ordinary people must educate themselves and exercise their economic leverage if we are to avoid social and environmental destruction.
