Andrew Haldane, Chief Economist at the Bank of England, (who is lined up to chair the Government’s Industrial Strategy Council) has said the decline of trade unionism as a key reason for the stagnation in real wages over the last ten years.
âThe world of work is being reshaped in many advanced economies by the secular fall in the degree of unionisation and collective bargaining, by changes in employment contracts and working patterns and by rises in the degree of concentration and automation in the company sector. By reducing workersâ âpay powerâ, they too have depressed wage growth, actually and prospectively,â he said in a speech to trade unions and business.
He described the past decade as âvery unusual by historical standardsâ in that employment levels rose but wage levels did not.
A significant fall in unionisation was one of the main drivers behind this, he said, noting that wage premiums for those who are members of a union typically fall in the range of about 10-15%.
â…a 10 percentage point rise in the degree of unionisation raises wage growth by around 25 basis points per year,â he explained.
âOver recent decades, unionisation rates have fallen by 30 percentage points. Using the long-run estimates, that will have lowered wage growth by around 0.75 percentage points per year over the past 30 years, a significant effect.
âConsistent with it, the sharpest falls in unionisation came in the 1970s and 1980s, coinciding with falls in the UK labour share. Rolling regressions suggest the effects of unionisation on pay were largest during this period.
âIf we look at the sectoral level, similar effects are seen. Sectors of the UK economy with higher levels of unionisation have seen smaller falls in their labour shares. Over the past few decades, a sector like administration and support activities with under 10% unionisation rates has seen its labour share decline, while a sector like education with a unionisation rate close to 50% has seen its labour share rise.â
Haldane also pointed to low productivity, increased automation and the rise of insecure work as factors in the real wage stagnation.
