If the central bank is maintaining an exchange rate that is consistent with myndell 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.

Any exogenous changes affecting the IS curve such as government spending changes will be exactly offset fleminb 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.

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. The shift results in an incipient rise in the interest rate, and hence upward pressure on the exchange rate value of the domestic currency as foreign funds start to flow in, attracted by the higher interest rate.

If the global interest rate increases, shifting the BoP curve upward, capital flows out to take advantage of the opportunity. Economics models International macroeconomics Open economy macroeconomics.

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 — feming accommodate this outflow. 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 mundel, right, and the interest rate remains equal to the world rate of interest.

The reason is that a large open economy has the characteristics of both an autarky and a small open economy. This principle is frequently called the ” modlle trinity ,” “unholy trinity,” “irreconcilable trinity,” “inconsistent trinity,” policy trilemma,” or the “Mundell—Fleming trilemma. 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.

Higher lagged income or a lower real interest rate leads to higher investment spending. Therefore, the rise in government spending will have no effect on the national GDP or interest rate. 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. 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.

Under less than perfect capital mobility, the depreciated exchange rate shifts the BoP curve somewhat back down. Thus, a monetary expansion, in the short run, does not necessarily improve the trade balance. This result is not compatible with what the Mundell-Fleming predicts.

Under perfect capital mobility, the new BoP curve will be horizontal at the new world interest rate, so the equilibrium domestic interest rate will fle,ing the world interest rate. However, the exchange rate is controlled by the local monetary authority in the framework of a fixed exchange rate system. 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.

Under flexible exchange ratesthe exchange rate is the third endogenous variable while BoP is set equal to zero. 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. Oe 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.

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. Muhdell higher e leads to higher net exports. Retrieved from ” https: Under perfect capital mobility, the BoP curve is always horizontal at the level of the world interest rate.

An increase in government expenditure mdle the IS curve to the right. Views Read Edit View history. 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. Under the Mundell—Fleming framework of a small economy facing perfect capital mobility, the domestic interest rate is fixed and equilibrium in both markets can only be maintained by adjustments of the nominal exchange rate or the money supply by international funds flows.

Consider an exogenous increase in government expenditure. Development Growth Monetary Political economy. Higher disposable income or a lower real interest rate nominal interest rate minus expected inflation leads to higher consumption spending. Increased government expenditure shifts the IS curve to the right. 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.

The strengthening of the currency will mean it is more expensive 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.

But under perfect capital mobility, any such sterilization would be met by further offsetting international flows.

This keeps the domestic currency’s exchange rate at its targeted level. 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. This depreciates the local currency and boosts net exports, shifting the IS curve to the right. 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.

However, in reality, the world ld rate is different from the domestic rate. Again, this keeps the exchange rate at its targeted level. From Wikipedia, the free encyclopedia.

Sargent Adam Smith Knut Wicksell. Whereas the traditional IS-LM model deals with economy under autarky or a closed economythe Mundell—Fleming model describes a small open economy.

In a system of flexible exchange rates, central banks allow the exchange rate to be determined by el forces alone. Under the fixed exchange rate system, the central bank operates in the foreign exchange market to maintain a specific exchange rate.

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.
