Question: Has any research attempted to link the so-called "productivity growth slowdown"in the US (or elsewhere) to demographic changes in the labor force? More narrowly, I'm interested in research that has rejected changes in the gender/ethnic/racial/age make-up of the labor force as a cause of slower rates of productivity growth in recent decades. Thanks for any leads. Eric .. Eric Nilsson Department of Economics California State University San Bernardino, CA 92407 [EMAIL PROTECTED]
