In this work, we study the dynamics of Solow’s economic growth model assuming that the labor force growth rate function, n(t), is a solution of a delay differential equation. This approach is motivated by the fact that there are delays in entering and retiring an individual from the labor...

This paper proposes conditions for the existence and uniqueness of solutions to systems of linear differential or algebraic equations with delays or advances, in which some variables may be non predetermined. The obtained conditions represent the counterpart of the Blanchard and Kahn conditions...
