DYNAMIC ANALYSIS OF AN ENDOGENOUS GROWTH MODEL WITH INVESTMENT-SPECIFIC TECHNOLOGICAL CHANGE

摘要

This paper examines a dynamically optimal subsidy policy in a continuous-time version of the endogenous growth model developed by Rrusell (Krusell, P. (1998) "Investment-Specific R&D and the Decline in the Relative Price of Capital", Journal of Economic Growth, vol. 3, no. 2, pp. 131-141), in which investment-specific technological progress occurs endogenously because of R&D performed by monopolistic firms. It is demonstrated that a combination of the time-invariant subsidy for investment and the time-variant subsidy for R&D enables the market equilibrium to replicate the socially optimal allocation.
