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...

In this paper, we present a simple vintage capital growth model in which both exogenous and endogenous fluctuations sources are present. Indeed, it can be seen as a particular case of Caballero and Hammour (1996)'s creative destruction model, with advantage that analytical characterization of...

This paper studies the conditions under which an IT revolution may occur and have permanent effects on long-term growth. To this end, we construct a multi-sectoral growth model with endogenous embodied technical progress. The R&D sector expands the range of softwares. The capital sector produces...

We develop a tractable general theory for the study of the economic and demographic impact of epidemics, notably its distributional consequences. To this end, we build up a three-period overlapping generations model where altruistic parents choose optimal health expenditures for their children...

This paper analyzes the equilibrium dynamics of an AK-type endogenous growth model with vintage capital. The inclusion of vintage capital leads to oscillatory dynamics governed by replacement echoes, which additionnally influence the intercept of the balanced growth path. These features, which...

Consider a country with two regions that have developed differently so that their current levels of energy efficiency differ. Each region's production involves the emission of pollutants, on which a regulator might impose restrictions. The restrictions can be related to pollution standards that...
