IT was FA Hayek,
an economics Nobel prize winner of immeasurably greater distinction than Paul
Krugman, who put it best. In his book the Fatal Conceit, he launched a
devastating attack on those who believe that elites can mould and control
humanity’s destiny. Central direction is impossible, a limitation those in
authority never accept.
Past fatal
conceits include the view that private property and markets can be abolished,
and replaced by pure socialism and central planning, whereby a small group
decides what is produced, what is consumed and who works where and gets what.
But we remain plagued by many other, contemporary fatal conceits. Here are two
especially pernicious ones.
The first is the
belief that governments can endlessly create growth out of thin air by
manipulating aggregate demand – cutting rates, printing money or borrowing and
spending more. Of course, such actions can have a huge effect. Monetary policy
can be extremely potent; the cost of borrowing is the most important price in
the economy and the quantity of money, and the speed at which it circulates, is
fundamental to the health of an economy, because money is used in every single
exchange. It may well have made sense to cut interest rates in China, for
example, as the Beijing authorities did yesterday for the first time since
2008. Varying public spending to manipulate GDP, however, is pretty useless at
the best of times.
