I believe that the consensus view among students of long term growth is that the period 1945 - 70 was the exceptional period and subsequent experience is closer to the long term experience since the beginning of the Industrial R Revolution in the late 18th century. Certainly the present experience has little to do with Keynes' worry about the onset of a stationary state which was to occur because of a drying up of new investment opportunities. The continued development of new technologies has implied no such drying up, although the effects of the latest wave of new innovations are quite different on the nature of employment, the distribution of income and other economic variables than growth experiences of the recent past.

It seems that the average growth rate of the industrialised countries has been declining, with only (historically) minor cyclic departures, since the early 1950s. The trend is strong and robust and is confirmed for a variety of measures of growth, and definitions of the industrialised countries. I am intrigued that this appears to have been overlooked or at least, is not widely known or referred to. So I wonder if in fact, other research has come up with similar results. If anyone knows of such, do get in touch.
