Treasury and Work and Pensions

I am grateful to the hon. Gentleman for giving way. Does he not agree that productivity growth can be a misleading statistic if taken on its own? A growing economy brings the most marginal factors of production into production, whereas a shrinking economy loses them; therefore, it is possible for an economy in recession to have higher average productivity at the margins than a growing economy. Is that not so, and why does the hon. Gentleman include that misleading quality in his amendment?
