In this paper, an endogenous growth model is built up incorporating Schumpeterian growth and embodied technological progress. Under embodiment, long run growth is affected by the following effects: (i) obsolescence costs add to the user cost of capital, reducing the research effort; and (ii) the...

We construct a vintage capital model `a la Whelan (2002) with both exogenous embodied and disembodied technical progress, and variable utilization of each vintage. The lifetime of capital goods is endogenous and it relies on the associated maintenance costs. We study the properties of the...

In order to assess the importance of embodiment, we build up an endogenous growth model in which learning by doing is the engine of both embodied and disembodied technological progress. In sharp contrast to Phelps (1962), we show that a change in the composition of technical change affects the...
