Abstract:
We prove the existence of an optimal growth path in an economy where goods that are not consumed are wither invested in next period or in R&D with overall non-convex production possibilities, ising results of non-linear functional analysis in weighted Lp spaces of Chichilnisky (Journal of Optimication Theory and Applications, 1977, 61, no. 2. 504-520) and (Journal of Mathematical Economics, 1981, 8, 1-14).
