Abstract
In this paper, we examine various exchange rate regimes, paying particular attention to what difference the monetary-fiscal policy choices of governments make. The exchange rate may be market-determined or fixed, and if fixed, either cooperatively or by one government alone. Further, capital controls may or may not apply. Our most important result, quite general, we believe, is that absent capital controls the equilibrium exchange rate of the floating rate regime is indeterminate. It makes no sense to advocate floating rates and unfettered international borrowing and lending.
