| Abstract: | This article studies the dynamics of an overlapping generations model with capital, money and cash-in-advance constraints. The economy can exhibit two different regimes. In the first one, the cash-in-advance constraint is binding and money is a dominated asset. In the second one, the constraint is strictly satisfied and money has the same return as capital. When the second regime holds on a finite number of periods, we say that the economy experiences a temporary bubble. We prove that temporary bubbles can exist in an economy, which would experience under-accumulation without money. We also show that cyclical bubbles may occur. |
