The IS curve is downward sloped and the LM curve is upward sloped, as in the closed economy IS-LM analysis; the BoP curve is upward sloped unless there is perfect capital mobility, in which case it is horizontal at the level of the world interest rate. Dde the central bank were to conduct open market operations in the domestic bond market in order to offset these balance-of-payments-induced changes in the money supply — a process called sterilizationit would absorb newly arrived money by decreasing its holdings of domestic bonds or the opposite if money were flowing out of the country.
This principle is frequently called the ” impossible trinity ,” “unholy trinity,” “irreconcilable trinity,” “inconsistent trinity,” policy trilemma,” or the “Mundell—Fleming trilemma.
Higher lagged income or a lower real interest rate leads to higher investment spending. Basic assumptions of the model are as follows: However, this increase in the interest modl attracts foreign investors wishing to take advantage of the higher rates so they demand the domestic currency therefore it appreciates.
This will mean that domestic interest rates and GDP rise. If there is pressure to appreciate the domestic currency’s exchange rate because the currency’s demand exceeds its supply in the foreign exchange market, the local authority buys foreign currency with domestic currency to increase the domestic currency’s supply in the foreign exchange market.
Whereas the traditional IS-LM model deals with economy under autarky or a closed economythe Mundell—Fleming model describes a small open economy. This depreciates the local currency and boosts net exports, shifting the IS curve to the right.

Canadian Journal of Economic and Political Science. In particular, it may not face perfect capital mobility, thus allowing internal policy measures to affect the domestic interest rate, and it may be able to sterilize balance-of-payments-induced changes in the money supply as discussed above. To maintain the flfming exchange rate, the central bank must accommodate the capital flows in or out which are caused by a change of the global interest rate, in order to offset pressure on the exchange rate.
From Wikipedia, the free encyclopedia. Journal of International Economics. The Mundell—Fleming model applied to a small open economy facing perfect capital mobility, in which the domestic interest rate is exogenously determined by the world interest rate, shows stark differences from the closed economy model. Increased government expenditure shifts the IS curve to the right. But under perfect capital mobility, any such sterilization would be met by further offsetting international flows.
Again, this keeps the exchange rate at its targeted level. If the global interest rate declines below the domestic rate, the opposite occurs. This puts pressure on the home currency to depreciate, so the central bank must buy the home mundelk — that is, sell some of its foreign currency reserves — to accommodate this outflow.

Under flexible exchange ratesthe exchange rate is the third endogenous variable while BoP is set equal to zero. Reprinted in Cooper, Richard N.
Sargent Adam Smith Knut Wicksell. In the IS-LM model, the domestic interest rate is a key mjndell in keeping both the money market and the goods market in equilibrium.
In contrast, under fixed exchange rates e is exogenous and the balance of payments surplus is determined by the model. Nevertheless, Dornbusch concludes that monetary policy is still effective even if it worsens a trade balance, because a monetary expansion pushes down interest rates and encourages spending.
In this graph, under less than perfect capital mobility the positions of both the IS curve and the BoP curve depend on the exchange rate as discussed belowsince the IS-LM graph is actually a two-dimensional cross-section of a three-dimensional space involving all of the interest rate, income, and the exchange rate.
Views Read Edit View history. A decrease in the money supply causes the exact opposite process. Consider an exogenous increase in government expenditure. An increase in the global interest rate shifts the BoP curve upward and causes capital flows out of the local economy. But in the Mundell—Fleming open economy model with perfect capital mobility, monetary policy becomes ineffective. If the central bank is maintaining an exchange rate that is consistent with a balance of payments surplus, over time money will flow into the country and the money supply will rise and vice versa for a payments deficit.
But for a small open economy with perfect capital mobility and a flexible exchange rate, the domestic interest rate is predetermined by the horizontal BoP curve, and so by the LM equation given previously there is exactly one level of output that can make the money market be in equilibrium at that interest rate.
Development Growth Monetary Political economy. To maintain the exchange rate and eliminate pressure on it, the monetary authority purchases foreign currency using domestic funds in order to shift the LM curve to the right. After the subsequent equations are substituted into the first three equations above, one has a system of three equations in three unknowns, two of which are GDP and the domestic interest rate.
Under both types of exchange rate regime, the nominal domestic money supply M is exogenous, but for different reasons. The reason is that a large open economy has the characteristics of both an autarky and a small open economy. Retrieved from ” https: Higher disposable income or a lower real interest rate nominal interest rate minus expected inflation leads to higher consumption spending.
flemign In a system of fixed exchange rates, central banks announce an exchange rate the parity rate at which they are prepared to buy or sell any amount of domestic currency.
The Mundell—Fleming model portrays the short-run relationship between an economy’s nominal exchange rate, interest rate, and output in contrast to the closed-economy IS-LM model, which focuses only on the relationship between the interest rate and output.
