Much has been written on the global decline of the corporate labour share (defined as the share of corporate value added going to wages, salaries and benefits). The IMF and OECD worry about this trend, linking it to decreasing wages and rising inequality. And economists are hard at work looking for an explanation: prominent hypotheses range from automation and ‘superstar’ firms to offshoring. But is there really a global decline in the non-housing/business labour share? Not if you properly exclude housing income and account for self-employment, as described in a recent Staff Working Paper. Adjusting for housing and self-employment, labour shares have remained stable across most advanced economies except in the US, where the labour share still declines by 6% since 1980 (Figure 1).
Seeing into the future is always difficult. But in the world of macroeconomics, just trying to look at the past can be a challenge. Official estimates of economic growth in the UK are regularly revised, so forecasts for growth over the next year have to be made on the basis of an ever-changing report card for the previous year. This post tackles some of the most common questions about UK GDP revisions, a topic close to the heart of many users of the UK’s National Accounts. Are the initial estimates of growth biased? Can you predict revisions? Does UK data get revised more than other countries? And which parts of early estimates of GDP should be approached with caution?
