We capture the idea that firms innovate in order to try to escape - albeit temporarily - from the pressure of competition exerted on them by their rivals. At each date, an industry...

In this paper we propose a unifying approach to study optimal growth models with bounded or unbounded returns. We prove existence of optimal solutions. We prove also, without using contraction method, that the value function is the unique solution to the Bellman equation in some classes of...
