Floquet theory and economic dynamics

Floquet theory is an appropriate tool for studying ordinary linear recurrence and differential equations with periodic coefficients, and is a generalization of the theory for constant coefficients. Floquet theory has still not found its way into economics, although it seems to be relevant for economic dynamics. This article contains as well as a discussion of this relevance and an illustration of it in the context of the Samuelson-Hicks multiplier-accelerator model.
