Development Growth Monetary Political economy. Investment and consumption increase as the interest rates decrease, and currency depreciation improves the trade balance.

An expansionary monetary policy resulting in an flemming outward shift of the LM curve would make capital flow out of the economy. Under perfect capital mobility, the BoP curve is always horizontal at the level of the world interest rate. If the global interest rate increases, shifting the BoP curve upward, capital flows out to take advantage of the opportunity.

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 molde is perfect capital mobility, in which case it is horizontal at the level of the world interest rate. In a system of flexible exchange rates, central banks allow the exchange rate to be determined by market forces alone. Mubdell an exogenous increase in government expenditure.

In contrast, under fixed exchange rates e is exogenous and the balance of payments surplus is determined by the model. An increase in money supply shifts the LM curve to the right.

Mundell–Fleming model

He adds that, in the short run, fiscal policy works because it raises interest rates and the velocity of money. 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 mkndell rise and vice versa for a payments deficit.

When the latter goes up, the BoP curve shifts upward by the same amount, and stays there. This keeps the domestic currency’s exchange rate at its targeted level. In the very short run the money supply is normally predetermined by the past history of international payments flows.


An increase in the global interest rate shifts the BoP curve upward and causes capital flows out of the local economy.

Thus, a monetary expansion, in the short run, does not necessarily improve the trade balance. If 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.

From Wikipedia, the free encyclopedia. This puts pressure on the home currency to depreciate, so the central bank must buy the home currency — that is, sell some of its foreign currency reserves — to accommodate this outflow.

In the IS-LM model, the domestic interest rate is a key component in keeping both the money market and the goods market in equilibrium. This page was last edited on 7 Novemberat To maintain the umndell rate and eliminate pressure on it, the monetary authority purchases foreign currency using domestic funds in order munddll shift the LM curve to the right. 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.

Journal of International Economics. It is worth noting that some of the results from this model differ from those of the IS-LM model because of the open economy assumption. This will mean that domestic interest munrell and GDP rise. Higher lagged income or a lower real interest rate leads to higher investment spending.

Mundell–Fleming model – Wikipedia

In the closed economy model, if the central bank expands the money supply the LM curve shifts out, and as a result income goes up and the domestic interest rate goes down. The decrease in the money supply resulting from the outflow, shifts the LM curve mundelk the left until it intersect the IS and Mod,e curves at their intersection.


But in the Mundell—Fleming open economy model with perfect capital mobility, monetary policy becomes ineffective. However, under perfect capital modlf the BoP curve is simply horizontal at a level of the domestic interest rate equal to the level of the world interest rate. Morle 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.

One of the assumptions of the Mundell—Fleming model is that domestic and foreign securities are perfect substitutes. This principle is frequently called the ” impossible trinity ,” “unholy trinity,” “irreconcilable trinity,” “inconsistent trinity,” policy trilemma,” or the “Mundell—Fleming trilemma.

Under both types of exchange rate regime, the nominal domestic money supply M is exogenous, but for different reasons. Under flexible exchange ratesthe exchange rate is the third endogenous variable while BoP is set equal to zero.

Economics models International macroeconomics Open economy macroeconomics. Any exogenous changes affecting the IS curve such as government spending omdle will be exactly offset by resulting exchange rate changes, and the IS curve will end up in its original position, still intersecting the LM and BoP curves at their intersection point. This result is not compatible with what the Mundell-Fleming predicts.

Whereas the traditional IS-LM model deals with economy under autarky or a closed economythe Mundell—Fleming model describes a small open economy. However, in reality, the world interest rate is different from the domestic rate. Modlf being said, capital outflow will increase which will lead to a decrease in the real exchange rate, ultimately shifting the IS curve right until interest rates equal global interest rates assuming horizontal BOP.
