The official measure of Q1 productivity growth currently looks likely to be revised down to almost -6% (annualized) – the worst in almost 70 years. As Goldman points out, even on a longer-term basis, the 4-, 8-, and 12-quarter trends are all in a 0.2%-0.6% range when the Q1 estimates are included, dramatically below consensus 2% estimates of the long-term trend.
