C. Likely impacts of automation?

Doomsayers forecast that robots will fully automate and so steal all our jobs – others say ‘bring them on – the sooner the better’

A report for the World Economic Forum estimates that technology will create about two million jobs worldwide by 2020 – but displace seven million

This is worrying enough for the educated and financially secure according to Tim Worstall, a journalist, but alarming if you are without a job or in low-paid, patchy work

He quotes Paul Krugman, famous Nobel economics laureate: “The average wage in an economy is determined by the average productivity of labour in that economy – if productivity rises, wages rise, and automation increases labour productivity

Hence the barber in Chester earns more than a barber in Calcutta – both are doing the same task using the same gear with the same efficiency but the higher productivity of the alternative uses for UK labour pull up that barber’s wage

Krugman also says that, as automation makes the labour running machines more valuable, so real wage rates rise – and such rises are needed to increase demand for the myriad of things being made by those machines which must be consumed – by people

Others disagree

If two skilled machinists are replaced by an automated machine that only requires one unskilled person to keep it loaded, the alternative jobs available to them might be a shelf-stacker in a supermarket or an Uber driver – so the rise in productivity has not led to a rise in average wages

But others point out that automation is more likely to produce ten times the output of the previous two skilled machinists and so require ten unskilled persons to load up – a cheaper product will then result, so many more units will be sold to a lot more poorer people

That way, skilled weavers were replaced by machines and high quality cloth that only the super-rich could afford became available to everyone – likewise, expensive hand-built motor cars were replaced by much cheaper cars made on mechanised production/ assembly lines, starting with Henry Ford’s ‘Model T’

Demand soared, output soared, unit costs dived, selling prices became a lot cheaper and so affordable – almost everyone, whether a customer or supplier, was happy

As stuff becomes cheaper, whole new sectors can grow

And if unit prices drop relative to wages, the effect is the same as if wages had risen – hence, society becomes wealthier not by people getting higher wages but through goods and services getting cheaper

So, if automation truly takes over, the price of everything may well drop to zero

Everyone will then be able to afford anything with only the most minimal amount of work needed

    It’s a fascinating subject, as described by you, and clearly one which will fundamentally alter markets forever.
