Abstract:
This note contains some general and idiosyncratic reflections on the current state of neoclassical growth theory. It expresses some surprise at the lack of attention both to multi-sector growth models and to multi-country models with trade and capital flows. It also suggests that there might be value in further analysis of some old topics like capital-labor substitution with an expanded definition of capital, and the interaction of growth and medium-run phenomena (or, to put it differently, the interaction of demand-side and supply-side variations).
