Today (R4 at 8.30am) had a section on "productivity" - http://www.bbc.co.uk/programmes/b099v33m
It is claimed - yet again - that the UK falls behind other countries in terms of this measure, and also that London has a much higher productivity than the rest of the UK. But what does that really mean?
More "units" produced in a given time? Greater value of output in a given time? Some other more or less arbitrary measure?
Are comparisons with other countries sensible anyway, as their outputs may be different, and the measures used in each may not be the same or even remotely comparable?
There ie even a hidden assumption that higher productivity is a good thing - but without knowing what is being measured, and what the effects are, that is also uncertain.
