Reinhart & Reinhart On Recovery

Excellent opinion piece in todays Financial Times by Carmen Reinhart and Vincent Reinhart. Carmen Reinhart co-authored with Kenneth S. Rogoff now famous study on public and foreign debt: Growth in a Time of Debt.

Ben Bernanke, chairman of the Federal Reserve, painted a sober but reassuring picture of US prospects. The basis for sustained recovery is in place, and canny Fed officials are now alive to the dangers of both deflation and inflation. Similarly Jean Claude Trichet, head of the European Central Bank, spoke about how the dust had begun to settle on the crisis. Policymakers and financial markets seem to be looking at what comes next.

Such optimism, however, may be premature. We have analysed data on numerous severe economic dislocations over the past three-quarters of a century; a record of misfortune including 15 severe post-second world war crises, the Great Depression and the 1973-74 oil shock. The result is a bracing warning that the future is likely to bring only hard choices.

Our research found real per capita gross domestic product growth tends to be much lower during the decade following crises. Unemployment rates are higher, with the most extreme increases in the most advanced economies that experienced a crisis. In 10 of the 15 episodes we studied, unemployment never fell back to its pre-crisis level, not in the following decade nor right up to the end of 2009.

It gets worse. Where house price data are available, 90 per cent of the observations over the decade after a crisis are below their level the year before the crisis. Median prices are 15 to 20 per cent lower too, with cumulative declines as large as 55 per cent. Credit is also a problem. It expands rapidly before crises, but post-crash the ratio of credit to GDP declines by an amount comparable to the pre-crisis surge. However, this deleveraging is often delayed and protracted.

Perceptions aside, at Jackson Hole, policymakers debated whether further measures to stimulate demand were needed. History shows that today’s problems could certainly materialise as a consequence of the failure to provide sufficient economic stimulus. In particular, a collapse in financial intermediation can reduce the availability of loans. This lack of access to credit, in turn, makes households and business less able to spend, lengthening and deepening the downturn. In such circumstances slow growth often becomes a self-fulfilling prophecy produced by timid authorities, who neither supported spending nor dealt with the capital-adequacy problems at large banks.

However, it is also possible that economic contraction and a slow recovery can dent aggregate supply, otherwise known as an economy’s ability to produce efficiently. In this scenario, much less discussed in current debates, a sustained stretch of below-trend investment, alongside the depreciation of human capital that comes from high unemployment, hits the level and growth rate of potential output. That is, the unemployment rate stays high because it has been high.

And a conclusion:

A prudent post-crisis policy, therefore, must be alert to threats both to supply and demand, not demand alone. But the bigger worry remains the assumption that dust has begun to settle; that the shock from the crisis is temporary, when it is likely to be deep and persistent. Today, as in the past, over-optimistic fiscal authorities are over-estimating tax revenues. Financial supervisors want to believe that troubled banks are temporarily illiquid, not permanently insolvent. And central bankers like Mr Bernanke may soon attempt to restore employment to unattainably high levels. If they do so, the road to recovery will be long, and the lessons of history will have been ignored once more.
