20. Show graphically and compare the results of an expansionary monetary policy and foreign trade policy in a small open economy with a low degree of capital mobility and a floating exchange rate regime.
To compare the effects of an expansionary monetary policy and a foreign trade policy on a small open economy with a low degree of capital mobility and a floating exchange rate regime, we can use the Aggregate Demand-Aggregate Supply (AD-AS) model.
In this type of economy, the exchange rate is determined by the market, and the central bank can only influence the money supply through open market operations. In addition, capital flows are limited, so changes in interest rates have a limited effect on investment and savings decisions.
An expansionary monetary policy involves the central bank increasing the money supply through open market operations or by lowering interest rates. This leads to a shift in the AD curve to the right, as shown in the graph below:
graph
As a result of the increase in aggregate demand, output and employment levels rise, and the price level increases. In the short run, this policy leads to an increase in inflation, but in the long run, the economy returns to its natural rate of output, and the price level stabilizes.
A foreign trade policy involves government interventions to increase exports or reduce imports. For example, the government could subsidize exports, impose tariffs on imports, or impose quotas on imports. This leads to a shift in the AD curve to the right, as shown in the graph below:
graph
As a result of the increase in exports and reduction in imports, output and employment levels rise, and the price level increases. In the short run, this policy leads to an increase in inflation, but in the long run, the economy returns to its natural rate of output, and the price level stabilizes.
Comparing the two policies, we can see that both lead to an increase in output, employment, and the price level in the short run. However, an expansionary monetary policy has a larger effect on the economy's price level, while a foreign trade policy has a larger effect on the economy's output and employment levels.
Overall, the choice between these two policies depends on the goals of the government. If the government wants to stimulate economic growth and employment, a foreign trade policy may be more effective. If the government wants to control inflation, an expansionary monetary policy may be more appropriate.
19. Show graphically and compare the results of an expansionary fiscal and monetary policy in a small open economy with perfect capital mobility and a floating exchange rate regime.
To show the effects of an expansionary fiscal and monetary policy in a small open economy with perfect capital mobility and a floating exchange rate regime, we can use a diagram of the economy's aggregate demand and supply.
Assuming that the economy is initially in equilibrium at point A, where the aggregate demand (AD) and aggregate supply (AS) curves intersect, an expansionary fiscal policy and an expansionary monetary policy would shift the AD curve to the right.
Expansionary fiscal policy involves an increase in government spending and/or a decrease in taxes, while expansionary monetary policy involves an increase in the money supply and/or a decrease in interest rates.
The diagram below shows the initial equilibrium at point A, with AD and AS intersecting at output level Y1 and price level P1:
graph
Now, let's assume that the government implements an expansionary fiscal policy by increasing government spending. This would increase the demand for goods and services in the economy, shifting the AD curve to the right from AD1 to AD2:
graph
As a result, the new equilibrium point is at Y2 and P2, with higher output and higher prices. However, since this is a small open economy with perfect capital mobility and a floating exchange rate regime, the increase in demand for goods and services would also lead to an increase in the demand for the country's currency, which would appreciate the exchange rate. This is because higher demand for a currency would make it more valuable, and investors would want to hold more of it.
To show the effect of an expansionary monetary policy, we can assume that the central bank increases the money supply, which lowers interest rates and increases investment spending. This would also shift the AD curve to the right, from AD1 to AD3:
graph
As a result, the new equilibrium point is at Y3 and P3, with higher output and higher prices. Again, the increase in demand for goods and services would lead to an increase in the demand for the country's currency, which would appreciate the exchange rate.
Comparing the two policies, we can see that both expansionary fiscal and monetary policies increase output and prices in the short run. However, the effects on the exchange rate differ. Expansionary fiscal policy leads to a larger appreciation of the exchange rate compared to expansionary monetary policy. This is because fiscal policy directly increases demand for goods and services, while monetary policy indirectly stimulates demand by reducing interest rates and increasing investment spending.
Overall, the specific effects of expansionary fiscal and monetary policies in a small open economy with perfect capital mobility and a floating exchange rate regime depend on the specific characteristics of the economy and the policies themselves.

18. Show graphically and compare the results of an expansionary monetary policy and foreign trade policy in a small open economy with a low degree of capital mobility and a fixed exchange rate regime.
To show the effects of an expansionary monetary policy and a foreign trade policy in a small open economy with a low degree of capital mobility and a fixed exchange rate regime, we can use a diagram of the economy's aggregate demand and supply.
Assuming that the economy is initially in equilibrium at point A, where the aggregate demand (AD) and aggregate supply (AS) curves intersect, an expansionary monetary policy and a foreign trade policy would both shift the AD curve to the right.
Expansionary monetary policy involves an increase in the money supply and/or a decrease in interest rates, while a foreign trade policy involves an increase in exports or a decrease in imports.
The diagram below shows the initial equilibrium at point A, with AD and AS intersecting at output level Y1 and price level P1:
graph
Now, let's assume that the central bank implements an expansionary monetary policy by increasing the money supply, which lowers interest rates and increases investment spending. This would shift the AD curve to the right from AD1 to AD2:
graph
As a result, the new equilibrium point is at Y2 and P2, with higher output and higher prices. However, since this is a small open economy with a low degree of capital mobility and a fixed exchange rate regime, the increase in demand for goods and services would lead to an increase in imports, which would put pressure on the exchange rate to depreciate. In order to maintain the fixed exchange rate, the central bank would need to intervene by selling foreign reserves and buying domestic currency.
To show the effect of a foreign trade policy, we can assume that the government implements a policy that increases exports. This would shift the AD curve to the right from AD1 to AD3:
graph
As a result, the new equilibrium point is at Y3 and P3, with higher output and higher prices. However, since this is a small open economy with a low degree of capital mobility and a fixed exchange rate regime, the increase in exports would lead to an increase in demand for the country's currency, which would appreciate the exchange rate. In order to maintain the fixed exchange rate, the central bank would need to intervene by buying foreign reserves and selling domestic currency.
Comparing the two policies, we can see that an expansionary monetary policy leads to a depreciation of the exchange rate, while a foreign trade policy leads to an appreciation of the exchange rate. This is because an expansionary monetary policy increases demand for goods and services, which leads to an increase in imports, while a foreign trade policy increases demand for the country's currency, which leads to an increase in exports.
Overall, the specific effects of expansionary monetary and foreign trade policies in a small open economy with a low degree of capital mobility and a fixed exchange rate regime depend on the specific characteristics of the economy and the policies themselves. However, it is important to note that in a fixed exchange rate regime, the central bank must intervene to maintain the fixed exchange rate, which can limit the effectiveness of monetary and foreign trade policies.

17. Show graphically and compare the results of an expansionary fiscal policy and a devaluation policy in a small open economy with high capital mobility and a fixed exchange rate regime.
To show the effects of an expansionary fiscal policy and a devaluation policy in a small open economy with high capital mobility and a fixed exchange rate regime, we can use a diagram of the economy's aggregate demand and supply.
Assuming that the economy is initially in equilibrium at point A, where the aggregate demand (AD) and aggregate supply (AS) curves intersect, an expansionary fiscal policy and a devaluation policy would both shift the AD curve to the right.
Expansionary fiscal policy involves an increase in government spending and/or a decrease in taxes, while a devaluation policy involves a decrease in the exchange rate of the domestic currency relative to foreign currencies.
The diagram below shows the initial equilibrium at point A, with AD and AS intersecting at output level Y1 and price level P1:
graph
Now, let's assume that the government implements an expansionary fiscal policy by increasing government spending. This would shift the AD curve to the right from AD1 to AD2:
graph
As a result, the new equilibrium point is at Y2 and P2, with higher output and higher prices. However, since this is a small open economy with high capital mobility and a fixed exchange rate regime, the increase in demand for goods and services would lead to an increase in interest rates, which would attract foreign investors and cause an inflow of capital. This inflow of capital would appreciate the exchange rate, making exports less competitive and increasing imports, which would partially offset the expansionary fiscal policy.
To show the effect of a devaluation policy, we can assume that the central bank implements a policy that devalues the domestic currency relative to foreign currencies. This would shift the AD curve to the right from AD1 to AD3:
graph
As a result, the new equilibrium point is at Y3 and P3, with higher output and higher prices. The devaluation would make exports more competitive and reduce imports, which would enhance the effect of the expansionary policy. However, since this is a small open economy with high capital mobility and a fixed exchange rate regime, the devaluation would also lead to an increase in interest rates, which would attract foreign investors and cause an inflow of capital. This inflow of capital would partially offset the effect of the devaluation policy by appreciating the exchange rate.
Comparing the two policies, we can see that an expansionary fiscal policy leads to an appreciation of the exchange rate, while a devaluation policy leads to a depreciation of the exchange rate. This is because an expansionary fiscal policy increases demand for goods and services, which attracts foreign capital and appreciates the exchange rate, while a devaluation policy reduces the price of exports and makes them more competitive, which attracts foreign demand and depreciates the exchange rate.
Overall, the specific effects of expansionary fiscal and devaluation policies in a small open economy with high capital mobility and a fixed exchange rate regime depend on the specific characteristics of the economy and the policies themselves. However, it is important to note that in a fixed exchange rate regime with high capital mobility, the exchange rate is highly sensitive to capital flows, which can limit the effectiveness of expansionary fiscal and devaluation policies.

16. Show graphically and compare the results of foreign trade policy (increase in import customs duties) and expansionary fiscal policy in a small open economy with perfect capital mobility and a floating exchange rate regime.
To compare the effects of a foreign trade policy and an expansionary fiscal policy in a small open economy with perfect capital mobility and a floating exchange rate regime, we can use a diagram of the economy's aggregate demand and supply.
Assuming that the economy is initially in equilibrium at point A, where the aggregate demand (AD) and aggregate supply (AS) curves intersect, an increase in import customs duties and an expansionary fiscal policy would both affect the aggregate demand (AD) curve.
An increase in import customs duties would shift the AD curve to the left, as it would reduce demand for imported goods and increase their price. On the other hand, an expansionary fiscal policy would shift the AD curve to the right, as it would increase demand for goods and services.
The diagram below shows the initial equilibrium at point A, with AD and AS intersecting at output level Y1 and price level P1:
graph
Now, let's assume that the government implements an expansionary fiscal policy by increasing government spending. This would shift the AD curve to the right from AD1 to AD2:
graph
As a result, the new equilibrium point is at Y2 and P2, with higher output and higher prices. However, since this is a small open economy with perfect capital mobility and a floating exchange rate regime, the increase in demand for goods and services would lead to an increase in interest rates, which would attract foreign investors and cause an inflow of capital. This inflow of capital would appreciate the exchange rate, making exports less competitive and increasing imports, which would partially offset the expansionary fiscal policy.
Now, let's assume that the government implements a foreign trade policy by increasing import customs duties. This would shift the AD curve to the left from AD1 to AD3:
graph
As a result, the new equilibrium point is at Y3 and P3, with lower output and higher prices. The increase in import duties reduces demand for imports, but also reduces the availability of imported goods, which increases their price. This increase in import prices would lead to an increase in the price level, which partially offsets the reduction in demand for imports.
Comparing the two policies, we can see that an expansionary fiscal policy leads to an appreciation of the exchange rate, while a foreign trade policy leads to a depreciation of the exchange rate. This is because an expansionary fiscal policy increases demand for goods and services, which attracts foreign capital and appreciates the exchange rate, while a foreign trade policy reduces demand for imports, which reduces the demand for foreign currencies and depreciates the exchange rate.
Overall, the specific effects of foreign trade policy and expansionary fiscal policies in a small open economy with perfect capital mobility and a floating exchange rate regime depend on the specific characteristics of the economy and the policies themselves. However, it is important to note that in a floating exchange rate regime with perfect capital mobility, the exchange rate is highly sensitive to capital flows, which can limit the effectiveness of both foreign trade policy and expansionary fiscal policies.

15. Show graphically and compare the results of an expansionary monetary policy and foreign trade policy in a small open economy with a high degree of capital mobility and a floating exchange rate regime.
To compare the effects of an expansionary monetary policy and a foreign trade policy in a small open economy with a high degree of capital mobility and a floating exchange rate regime, we can use a diagram of the economy's aggregate demand and supply.
Assuming that the economy is initially in equilibrium at point A, where the aggregate demand (AD) and aggregate supply (AS) curves intersect, both an expansionary monetary policy and a foreign trade policy would affect the aggregate demand (AD) curve.
An expansionary monetary policy would shift the AD curve to the right, as it would increase the supply of money and lower interest rates, which would increase investment and consumption. On the other hand, a foreign trade policy, such as an increase in import customs duties, would shift the AD curve to the left, as it would reduce demand for imported goods and increase their price.
The diagram below shows the initial equilibrium at point A, with AD and AS intersecting at output level Y1 and price level P1:
graph
Now, let's assume that the central bank implements an expansionary monetary policy by lowering interest rates. This would shift the AD curve to the right from AD1 to AD2:
graph
As a result, the new equilibrium point is at Y2 and P2, with higher output and higher prices. However, since this is a small open economy with a high degree of capital mobility and a floating exchange rate regime, the lower interest rates would attract foreign investors and cause an inflow of capital. This inflow of capital would appreciate the exchange rate, making exports less competitive and increasing imports, which would partially offset the expansionary monetary policy.
Now, let's assume that the government implements a foreign trade policy by increasing import customs duties. This would shift the AD curve to the left from AD1 to AD3:
graph
As a result, the new equilibrium point is at Y3 and P3, with lower output and higher prices. The increase in import duties reduces demand for imports, but also reduces the availability of imported goods, which increases their price. This increase in import prices would lead to an increase in the price level, which partially offsets the reduction in demand for imports.
Comparing the two policies, we can see that an expansionary monetary policy leads to an appreciation of the exchange rate, while a foreign trade policy leads to a depreciation of the exchange rate. This is because an expansionary monetary policy increases investment and consumption, which attracts foreign capital and appreciates the exchange rate, while a foreign trade policy reduces demand for imports, which reduces the demand for foreign currencies and depreciates the exchange rate.
Overall, the specific effects of expansionary monetary policy and foreign trade policies in a small open economy with a high degree of capital mobility and a floating exchange rate regime depend on the specific characteristics of the economy and the policies themselves. However, it is important to note that in a floating exchange rate regime with high capital mobility, the exchange rate is highly sensitive to capital flows, which can limit the effectiveness of both expansionary monetary policy and foreign trade policies.

14. Show graphically and compare the results of an expansionary fiscal and monetary policy in a small open economy with low capital mobility and a floating exchange rate regime.
To compare the effects of an expansionary fiscal policy and an expansionary monetary policy in a small open economy with low capital mobility and a floating exchange rate regime, we can use a diagram of the economy's aggregate demand and supply.
Assuming that the economy is initially in equilibrium at point A, where the aggregate demand (AD) and aggregate supply (AS) curves intersect, both an expansionary fiscal policy and an expansionary monetary policy would affect the aggregate demand (AD) curve.
An expansionary fiscal policy would shift the AD curve to the right, as it would increase government spending and/or reduce taxes, which would increase consumption and investment. On the other hand, an expansionary monetary policy would shift the AD curve to the right, as it would increase the supply of money and lower interest rates, which would increase investment and consumption.
The diagram below shows the initial equilibrium at point A, with AD and AS intersecting at output level Y1 and price level P1:
graph
Now, let's assume that the government implements an expansionary fiscal policy by increasing government spending. This would shift the AD curve to the right from AD1 to AD2:
graph
As a result, the new equilibrium point is at Y2 and P2, with higher output and higher prices. However, since this is a small open economy with low capital mobility and a floating exchange rate regime, the increase in demand for domestic goods and services would not be offset by a capital inflow, as foreign investors are not highly interested in the economy. Thus, the increase in demand would lead to an increase in the relative price of domestic goods and services, which would appreciate the exchange rate and make exports less competitive.
Now, let's assume that the central bank implements an expansionary monetary policy by lowering interest rates. This would shift the AD curve to the right from AD1 to AD3:
graph
As a result, the new equilibrium point is at Y3 and P3, with higher output and higher prices. The lower interest rates would lead to an increase in investment and consumption, which would increase demand for domestic goods and services. However, since this is a small open economy with low capital mobility and a floating exchange rate regime, the lower interest rates would not attract foreign investors, as the economy is not highly attractive to foreign investors. Thus, the increase in demand would lead to an increase in the relative price of domestic goods and services, which would appreciate the exchange rate and make exports less competitive.
Comparing the two policies, we can see that both an expansionary fiscal policy and an expansionary monetary policy would lead to an appreciation of the exchange rate, making exports less competitive. However, an expansionary fiscal policy would also lead to an increase in government debt, while an expansionary monetary policy would not necessarily do so.
Overall, the specific effects of expansionary fiscal and monetary policies in a small open economy with low capital mobility and a floating exchange rate regime depend on the specific characteristics of the economy and the policies themselves. However, it is important to note that in a floating exchange rate regime with low capital mobility, the exchange rate is less sensitive to capital flows, which can limit the effectiveness of both expansionary fiscal policy and expansionary monetary policy.

13. Show graphically and compare the results of an expansionary fiscal policy and foreign trade policy (increase in customs duties) in a small open economy with perfect capital mobility and a fixed exchange rate regime.
To compare the effects of an expansionary fiscal policy and an increase in customs duties (a form of foreign trade policy) in a small open economy with perfect capital mobility and a fixed exchange rate regime, we can use a diagram of the economy's aggregate demand and supply.
Assuming that the economy is initially in equilibrium at point A, where the aggregate demand (AD) and aggregate supply (AS) curves intersect, both an expansionary fiscal policy and an increase in customs duties would affect the aggregate demand (AD) curve.
An expansionary fiscal policy would shift the AD curve to the right, as it would increase government spending and/or reduce taxes, which would increase consumption and investment. On the other hand, an increase in customs duties would shift the AD curve to the left, as it would increase the prices of imported goods and reduce the quantity demanded of these goods.
The diagram below shows the initial equilibrium at point A, with AD and AS intersecting at output level Y1 and price level P1:
graph
Now, let's assume that the government implements an expansionary fiscal policy by increasing government spending. This would shift the AD curve to the right from AD1 to AD2:
graph
As a result, the new equilibrium point is at Y2 and P2, with higher output and higher prices. However, since this is a small open economy with perfect capital mobility and a fixed exchange rate regime, the increase in demand for domestic goods and services would be offset by a capital inflow, as foreign investors are attracted to the economy. Thus, the increase in demand would lead to an increase in the relative price of domestic goods and services, which would appreciate the exchange rate and make exports less competitive.
Now, let's assume that the government implements an increase in customs duties. This would shift the AD curve to the left from AD1 to AD3:
graph
As a result, the new equilibrium point is at Y3 and P3, with lower output and higher prices. The increase in the prices of imported goods would reduce the quantity demanded of these goods, and the decrease in demand for foreign goods would lead to a decrease in demand for the domestic currency, which would depreciate the exchange rate and make exports more competitive.
Comparing the two policies, we can see that an expansionary fiscal policy would lead to an appreciation of the exchange rate, while an increase in customs duties would lead to a depreciation of the exchange rate. The expansionary fiscal policy would also lead to an increase in government debt, while the increase in customs duties would not necessarily do so.
Overall, the specific effects of expansionary fiscal policy and foreign trade policy in a small open economy with perfect capital mobility and a fixed exchange rate regime depend on the specific characteristics of the economy and the policies themselves. However, it is important to note that in a fixed exchange rate regime with perfect capital mobility, the exchange rate is highly sensitive to capital flows, which can limit the effectiveness of policies aimed at affecting the exchange rate.

12. Show graphically and compare the results of an expansionary monetary policy and a devaluation policy in a small open economy with high capital mobility and a fixed exchange rate regime.
To compare the effects of an expansionary monetary policy and a devaluation policy in a small open economy with high capital mobility and a fixed exchange rate regime, we can use a diagram of the economy's aggregate demand and supply.
Assuming that the economy is initially in equilibrium at point A, where the aggregate demand (AD) and aggregate supply (AS) curves intersect, both an expansionary monetary policy and a devaluation policy would affect the aggregate demand (AD) curve.
An expansionary monetary policy would shift the AD curve to the right, as it would lower interest rates, which would increase consumption and investment. On the other hand, a devaluation policy would also shift the AD curve to the right, as it would make exports cheaper and increase the quantity demanded of domestic goods.
The diagram below shows the initial equilibrium at point A, with AD and AS intersecting at output level Y1 and price level P1:
graph
Now, let's assume that the central bank implements an expansionary monetary policy by lowering interest rates. This would shift the AD curve to the right from AD1 to AD2:
graph
As a result, the new equilibrium point is at Y2 and P2, with higher output and higher prices. However, since this is a small open economy with high capital mobility and a fixed exchange rate regime, the increase in demand for domestic goods and services would be offset by a capital outflow, as domestic investors seek higher returns abroad. Thus, the increase in demand would lead to a decrease in the relative price of domestic goods and services, which would devalue the exchange rate and make exports more competitive.
Now, let's assume that the government implements a devaluation policy by intentionally reducing the value of the domestic currency relative to foreign currencies. This would shift the AD curve to the right from AD1 to AD3:
graph
As a result, the new equilibrium point is at Y3 and P3, with higher output and higher prices. The devaluation of the exchange rate would make exports cheaper and increase the quantity demanded of domestic goods, leading to an increase in demand for domestic goods and services.
Comparing the two policies, we can see that both an expansionary monetary policy and a devaluation policy would lead to an increase in output and prices. However, the expansionary monetary policy would lead to a decrease in the exchange rate, while the devaluation policy would intentionally devalue the exchange rate. The devaluation policy would also make exports more competitive, while an expansionary monetary policy would not necessarily do so.
Overall, the specific effects of an expansionary monetary policy and a devaluation policy in a small open economy with high capital mobility and a fixed exchange rate regime depend on the specific characteristics of the economy and the policies themselves. However, it is important to note that in a fixed exchange rate regime with high capital mobility, the exchange rate is highly sensitive to capital flows, which can limit the effectiveness of policies aimed at affecting the exchange rate.

11. Show graphically and compare the results of an expansionary fiscal policy and an expansionary monetary policy in a small open economy with low capital mobility and a fixed exchange rate regime.
To compare the effects of an expansionary fiscal policy and an expansionary monetary policy in a small open economy with low capital mobility and a fixed exchange rate regime, we can use a diagram of the economy's aggregate demand and supply.
Assuming that the economy is initially in equilibrium at point A, where the aggregate demand (AD) and aggregate supply (AS) curves intersect, both an expansionary fiscal policy and an expansionary monetary policy would affect the aggregate demand (AD) curve.
An expansionary fiscal policy would shift the AD curve to the right, as it would increase government spending, which would increase consumption and investment. On the other hand, an expansionary monetary policy would also shift the AD curve to the right, as it would lower interest rates, which would increase consumption and investment.
The diagram below shows the initial equilibrium at point A, with AD and AS intersecting at output level Y1 and price level P1:
graph
Now, let's assume that the government implements an expansionary fiscal policy by increasing government spending. This would shift the AD curve to the right from AD1 to AD2:
graph
As a result, the new equilibrium point is at Y2 and P2, with higher output and higher prices. Since this is a small open economy with low capital mobility and a fixed exchange rate regime, there would be no capital outflow to offset the increase in demand, and the exchange rate would remain fixed.
Now, let's assume that the central bank implements an expansionary monetary policy by lowering interest rates. This would also shift the AD curve to the right, but by a different amount, from AD1 to AD3:
graph
As a result, the new equilibrium point is at Y3 and P3, with higher output and higher prices. Again, since this is a small open economy with low capital mobility and a fixed exchange rate regime, there would be no capital outflow to offset the increase in demand, and the exchange rate would remain fixed.
Comparing the two policies, we can see that both an expansionary fiscal policy and an expansionary monetary policy would lead to an increase in output and prices. However, the specific effects of the policies would depend on their specific characteristics, such as the magnitude and timing of the policy measures.
Overall, in a small open economy with low capital mobility and a fixed exchange rate regime, both fiscal and monetary policies can be effective in stimulating output and prices, since there is no capital outflow to offset the increase in demand. However, policymakers must also consider the potential inflationary effects of these policies and the sustainability of the resulting fiscal deficit.
