I thought the concept of trying to capture intangibles died out in the 1980's

You know, "lets' introduce this new simplified expense report form, and it will save 15 minutes per month among our 4,000 employees across the country, and thus we will pick up 4 person-years of productivity"

To which smart senior managers would reply "OK, please outline which 4 people we could either re-assign to new responsibilities, or which 4 people we could name as redundant, an let go"...obviously you cannot...

As for this study, since a lot of women tend to work in "flat salary" and/or government roles, how would a forms processor at a government ministry increase the gdp if she stays in the office 15 minutes longer each day? How about a teacher?
