Monopolistic competition with investments in productivity

  • Igor BykadorovEmail author
Original Paper


We consider a monopolistic competition model with the endogenous choice of technology. We study the impact of technological innovation on the equilibrium and socially optimal variables. We obtained the comparative statics of the equilibrium and socially optimal solutions with respect to the technological innovation parameter and utility level parameter.
