LONDON (AFX) - Productivity growth in the UK has jumped to its fastest rate since last spring largely because the number of jobs has fallen sharply, reports the Financial Times, citing a study by Lloyds TSB and the Institute of Management Services. The study showed that January's sharp turnaround in productivity in the private sector was largely driven by service industries. However, the study also found that manufacturing productivity also increased at its fastest rate since March, but only because employment fell more rapidly than output.
