Nordhaus, “Are We Approaching an Economic Singularity? Information Technology and the Future of Economic Growth” (2015-09) articulates M06a. Extending the growth model to heterogeneous labour, Nordhaus shows that if unskilled labour is a perfect substitute for information capital its wage falls with capital prices; with a reservation wage its employment approaches zero.
