This paper generalizes Benhabib and Farmer [4], by allowing for a strictly positive time-to-build of capital. The introduction of a time-to-build delay yields a system of mixed functional di¤erential equations. We show that the system has a unique steady state. More important, we prove that the...

A comprehensive study of the linkages between demographic and economic variables should not only account for vintage specificity but also incorporate the relevant economic and demographic decisions in a complete optimal control set-up. In this paper, a methodological set-up allowing to reach...

In the automobile sector, it is a usual practice that independent carmakers engage in the development and production of a common car model, the so-called twin cars. From the point of view of the marketing literature, we claim that carmakers should not charge different brand premia on separate...

The effects of competition on growth are analyzed in the recent literature by comparing economies with the same market structure but different degrees of substitutability. In this note, we show that in a general equilibrium model with monopolistic competition à la Dixit-Stiglitz the effect of...

Differential equations with advanced and delayed time arguments may arise in the optimality conditions of simple growth models with delays. Models with investment gestation lags (time-to-build), consumption gestation lags (habit formation) or learning by using lie in this category. In this...
