This paper explores the role of replacement and innovation in shaping investment and productivity during episodes of lumpy adjustment in capital. To this purpose we use a rich firm-level panel of Spanish manufacturing data that combines information on equipment investment and firm's strategies....

Differential equations with advanced and delayed time arguments may arise in the optimality conditions of simple growth models with delays. Models with delayed adoption of new technologies, habit formation or learning-by-using lie in this category. In this paper we present new insight on the...
