Abstract: Potential output losses from the global financial crisis are estimated by comparing recent OECD published projections with a counter-factual assuming a continuation of pre-crisis productivity trends and a trend employment rate which is sensitive to demographic trends. Among the 19 OECD countries which experienced a banking crisis over the period 2007-11 the median loss in potential output in 2014 is estimated to be about 5½ per cent, compared with a loss in aggregate potential output across all OECD countries of about 3½ per cent. The loss does, however, vary widely across countries, being more than 10% for several smaller European, mainly euro area, countries. The largest adverse effects come from lower trend productivity, which is a combination of both lower total factor productivity and lower capital per worker. Despite large increases in structural unemployment in some countries, the contribution of lower potential employment is limited because the adverse effect on labour force participation is generally much less than might have been expected on the basis of previous severe downturns. This may partly reflect pension reforms and a tightening up of early retirement pathways. Pre-crisis conditions relating to over-heating and financial excesses, including high inflation, high investment, large current account deficits, high total economy indebtedness and more rapid growth in capital-per-worker are all correlated with larger post-crisis potential output losses. This suggests that underlying the potential output losses was a substantial misallocation of resources, especially of capital, in the pre-crisis boom period. On the other hand, more competition-friendly product market regulation is associated with smaller losses of potential output, suggesting that it facilitates a reallocation of resources across firms and sectors in the aftermath of an adverse shock and so helps to mitigate its consequences. JEL classification: E32; E44. Keywords: Banking crisis, financial crisis, global financial crisis, potential output.
