In this paper, we introduce adoption costs in a canonical vintage capital model. Adoption costs take the form of a direct loss in production during a fixed period of time. We explicitly characterize the optimal machine replacement policy as a function of the adoption period. Using an explicit...

In this paper, we introduce adoption costs in a vintage capital model. We assume that the incorporation of technological innovations into the production sector requires an extra labor cost during a fixed period. First, we show how adoption crucially matters in the shape of short run and...
