P.S. In an earlier paper of yours, on "Technical Progress and Evolution", which I found most interesting, I got confused right at the beginning and would be very grateful if you would straighten me out. You define N as cumulative output, c M as the Kca»Hisfei*B direct labor r N cost cost of the Nth unit, and as the cumulated direct labor A of N units. Accordidngly, eguation (6.2) is the integral of equation (6.1). So far so good. But on the next page you call N/C^ productivity, by which you presumably mean output per unit of labor. But isn't your definition of productivity a rather special one, very different from the usual definition, in that it is the average productivity averaged over the entire life-time irs of the plant or equipment. Is not the usual definition of productivity the differential of yours with respect to time?I get confused, because from your argument one gets the impression that those two productivities are one and the same thing. Is the answer to my puzzle that since you assume output to grow exponentially, those two very different productivity concepts grow at the same rate?
