So says Stephanie Flanders, in this broadcast from the Today programme in which she explores whether or not the growth in employment this week is a good thing. The key, of course, is productivity and the economy’s capacity to grow, and therefore to recover. She explains the interrelationship between manpower and output with her usual clarity,with a brief reference to both sides of the issue, and to the short term and long term consequences of the recent rise in private sector employment - thus giving an ideal essay plan!. This is such a key concept in AS macroeconomics (and A2 as well) that I think this two-and-a-half minute piece is well worth saving and using with new groups of economists next term.
