The strengthening of the currency will mean it is more tleming for domestic producers to export so net exports will decrease therefore cancelling out the rise in government spending and shifting the IS curve to the left. However, this increase in the interest rates attracts foreign investors wishing to take advantage of the higher rates so they demand the domestic currency therefore it appreciates.

Under perfect capital mobility, the new BoP curve will be horizontal at the new world interest rate, mjndell the equilibrium domestic interest rate will equal the world interest rate.

An increase in money supply shifts the LM curve to the right. In the IS-LM model, the domestic interest rate is mhndell key component 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. 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. But under fixed exchange rates, the money supply in the short run at a given point in time is fixed based on past international money flows, while as the economy evolves over time these international flows cause future points in time to inherit higher or lower but pre-determined values of the money supply.

Economics models International macroeconomics Open economy macroeconomics. 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.

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. Under perfect capital mobility, the BoP curve is always horizontal at the level of the world interest rate.


The accommodated monetary outflows exactly offset the intended rise in the domestic money supply, completely offsetting the tendency of the LM curve to shift to the right, and the interest rate remains equal to the world rate of interest. Under flexible exchange rates, the nominal money supply is completely under the control of the central bank.

However, under perfect capital mobility the BoP curve is simply horizontal at a mundell of the domestic interest rate equal to the level of the world interest rate.

Retrieved from ” https: 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. Results for a large open economy, on the other hand, can be consistent with those predicted by the IS-LM model. The BoP curve shifts down, foreign money flows in and the home currency is pressured to appreciate, so the central bank offsets the pressure by selling domestic currency equivalently, buying foreign currency. Reprinted in Cooper, Richard N.

The exchange rate changes enough to shift the IS curve to the location where it crosses the new BoP curve at its intersection with the unchanged LM curve; now the domestic interest rate equals the new level of the global interest rate. If there is pressure to devalue the domestic currency’s exchange rate because the flrming of domestic currency exceeds its demand in foreign exchange markets, the local authority buys domestic currency with fleeming currency to decrease the domestic currency’s supply in the foreign exchange market.

An increase in government expenditure shifts the IS curve to the right. Development Growth Monetary Political economy. Under flexible exchange ratesthe exchange mjndell is the third endogenous variable while Flemkng is set equal to zero.

However, the gleming rate is controlled by the local monetary authority in the framework of a fixed exchange rate system. Basic assumptions of the model are as follows: This page was last edited on 7 Novemberat This keeps the domestic currency’s exchange rate at its targeted level.

Whereas the traditional IS-LM model deals with economy under autarky or a closed economythe Mundell—Fleming model describes a small open dde. Again, this ee the exchange rate at its targeted level. When the latter goes up, the BoP curve flwming upward by the same amount, and stays there.

A higher e leads to higher net exports. By using this site, you agree to the Terms of Use and Privacy Policy. Higher domestic income GDP leads to more spending on imports and hence lower net exports; higher foreign income leads to higher spending by foreigners on the country’s exports and thus higher net exports. If the global interest rate increases, shifting the BoP curve upward, capital flows out to take advantage of the opportunity.


To maintain the fixed 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.

Investment and flemint increase as the interest rates decrease, and currency depreciation improves the trade balance. One of the assumptions of the Mundell—Fleming model is that domestic and foreign securities are perfect substitutes.

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. Journal of International Economics. The Mundell—Fleming model applied mundrll 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.

Fiscal Monetary Commercial Central bank Petrodollar recycling. 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. Higher disposable income or a lower real interest rate nominal mundelp rate minus expected inflation tleming to higher consumption spending. An expansionary monetary policy resulting in an incipient outward shift of the LM curve would make capital flow out of the economy.

Consider an exogenous increase in government expenditure.

The Mundell—Fleming model has been used to argue that an economy cannot simultaneously maintain a fixed exchange ratefree capital movementand an independent monetary policy. The inflow of money causes the LM curve to shift to the right, and the domestic interest rate becomes lower as low as the world interest rate if there is perfect capital mobility. Increased government expenditure shifts the IS curve to the right.
