A note on continuous time models with general cash-in-advance constraints

This note completely characterizes continuous time models with general cash-in-advance constraints in that money is demanded for purchasing not only consumption goods but also for making all or some investments. Examining the three-dimensional dynamics of an exogenous growth model with general cash-in-advance constraints is unique. Comparative static analysis shows that increased inflation or a strengthened cash-in-advance constraint lowers the level of the capital stock in the long run. We also show that the steady state is locally stable.
