Growth and the uncertain economic system Competition and a market economy support industrialisation and create higher living standards. The collapse of the world financial markets in 2008 was a failure of such a system and the ideas that underpinned it, not of individual policymakers. There was a misunderstanding of how the world economy worked. Many of the problems that concern governments – poverty, rising inequality, crumbling infrastructure – would be eased by rates of growth that before the financial crisis seemed quite normal. But the rate of economic growth has declined across the developed world. Some blame this on a slowing of innovation and productivity. Others say that the struggle to revive the world economy is a result of the disequilibrium that led to the crisis. Before the crisis, consumer spending was at unsustainably high levels in the United States (US), the United Kingdom and some other countries in Europe. It was at unsustainably low levels in Germany and China. The imbalance between countries increased – with resulting large trade deficits or surpluses. These imbalances were not irrational, they were the result of people struggling to behave rationally in a world of uncertainty and competition – all part of the market economy. Bad investments were made in housing in the US and some European countries, in construction in China and in the export sector in Germany. The most obvious symptom of the disequilibrium was the extraordinarily low interest rates. Central banks were trapped into a policy of low interest rates because of a belief that the solution to weak demand was further monetary stimulus. They were in a 'prisoner's dilemma': if any central bank raised interest rates, they would have risked a slowing of growth in their own country and given others an advantage. So, with interest rates close to zero and fiscal policy constrained by high government debt the objective of economic policy in a growing number of countries was to lower the exchange rate. The experience of stubbornly weak growth around the world since the crisis has led to a new pessimism about the ability of market economies to generate prosperity. By 2015 world recovery was slower than expected. Whatever can be said about the recovery since the 2008 crisis, it has been neither strong nor sustainable. There has been a continuing shortfall of demand and output from pre-crisis levels. Lost output and employment have revealed the true cost of the crisis and shaken confidence in our understanding of how economies behave. Many countries now see that they have taken monetary policy as far as it can go. Source: Sunday Telegraph, 28 February 2016
