"The assumption of perfect capital mobility can be taken to mean that all securities in the system are perfect substitutes. Because different currencies are involved, this implies that existing exchange rates are expected to persist indefinitely (even when the exchange rate is not pegged) and that spot and forward exchange rates are identical. All the complications associated with speculation, the forward market, and exchange-rate margins are thereby assumed not to exist. "
"To focus attention on policies affecting the level of employment, we assume unemployed resources, constant returns to scale, and fixed money wage rates; this means that the supply of domestic output is elastic and its price level constant. We assume further that saving and taxes rise with income, that the balance of trade depends only on income and the exchange rate, that investment depends on the rate of interest, and that the demand for money depends only on income and the rate of interest. Our last assumption is that the country under consideration is too small to influence foreign incomes or the world level of interest rates." "Monetary policy will be assumed to take the form of open market purchases of securities, and fiscal policy the form of an increase in government spending (on home goods) financed by an increase in the public debt. Floating exchange rates result when the monetary authorities do not intervene in the exchange market, and fixed exchange rates when they intervene to buy and sell international reserves at a fixed price. "
to keep it in historical context:
reading this gives one the G force glaring faced manic thrill
of a roaring blast off
on a mission to the moon !!!
