As I look around the largest factor is the growing service sector, including government and education, from which no productivity is evident. I have a large number of neighbours who are school teachers and get to see them leaving late, get home early, take summers off, endless teacher development days, the stress of rigorous courses such as Canoe Camping and their retirement in their early fifties. With all due respect to Messrs Pessoa and Van Reenen but the fact that global labor markets are allowing us to import cheap socks from China doesn’t seem to have the slightest impact on these individuals productivity.
