• Resumo em Inglês: In this work we analyze the e ect of technological innovations on the intertemporal capital allocation in models of economic growth. Speci cally, we use the economic growth models with heterogeneous capital due to time of usage (capital vintage), it became a decision problem of capital disposal and replacement in each cycle of production (Vintage Capital Model of Ramsey VCMR). We obtain for these models the optimal path of capital, consumption and production. In addition, we characterize the optimal initial stock of capital, wich has not been studied in the literature on this subject. Finally, when considering endogenous labor supply, we built a dynamic programming problem with lagged state variables for that with lagged state variables and we prove the existence of a value function for it. Thus, using the Bellman equation, we nd numerical solutions to the problem and analyze its sensitivity to innovations in the production process.
