The only good thing about the continuing barrage of bad economic news is that it could have been worse: all three rating agencies could have downgraded the US, stock markets could have fallen further and the US could have defaulted on its debt. The general view is now that in this, the next round of the Great Recession, there is a high risk of things getting worse, with no effective instruments at governments’ disposal. The first point is correct but the second is not quite right.

Throughout the crisis – and before it – Keynesian economists provided a coherent interpretation of events. Pre-crisis, America, and to a large extent the world economy, was sustained by a bubble. The breaking of the bubble has left a legacy of excess leverage and real estate. Consumption will therefore remain weak and austerity on both sides of the Atlantic now ensures the state will not fill the void. Given this, it is not surprising that companies are unwilling to invest – even those that can get access to capital.

Of course, those worried about the shortage of policy instruments are partially correct. Bad monetary policy got us into this mess but it cannot get us out. Even if the inflation hawks at the Federal Reserve can be subdued, a third bout of quantitative easing will be even less effective than QE2. Even that probably did more to contribute to bubbles in emerging markets, while not leading to much additional lending or investment at home.
