In a small open economy with floating exchange rates, what is the effect of expansionary fiscal policy on aggregate output?
💡 Explanation:In the Mundell-Fleming model, expansionary fiscal policy in a small open economy with floating rates triggers currency appreciation. This reduces net exports, which exactly offsets the initial increase in domestic demand, leaving total output unchanged.

How does the ‘crowding out’ effect primarily influence the private sector during periods of expansionary fiscal policy?
💡 Explanation:Crowding out occurs when increased government borrowing for fiscal expansion leads to higher interest rates, which in turn reduces (crowds out) private investment spending.

If a government sets a price floor above the market equilibrium price, what is the most likely economic outcome?

A country experiencing high unemployment and low inflation would most likely implement which fiscal policy measure to stimulate demand?

Under the ‘Impossible Trinity’ framework, what must a country sacrifice to maintain both a fixed exchange rate and an independent monetary policy?
💡 Explanation:The Mundell-Fleming Trilemma (Impossible Trinity) posits that a country cannot simultaneously achieve a fixed exchange rate, free capital movement, and an independent monetary policy. If a state chooses to fix its currency and control its interest rates, it must implement capital controls to prevent arbitrage.

Under a fixed exchange rate and perfect capital mobility, which policy is completely ineffective in influencing aggregate demand?
💡 Explanation:According to the Mundell-Fleming model, with a fixed exchange rate and perfect capital mobility, monetary policy is completely ineffective. An expansionary monetary policy (lowering interest rates) would cause massive capital outflow. To maintain the fixed exchange rate, the central bank must intervene by selling foreign reserves (and buying domestic currency), which perfectly offsets the initial increase in the money supply, thus negating any impact on domestic interest rates or aggregate demand. Fiscal policy is highly effective under these conditions.

What is the fundamental economic problem that necessitates the study of resource allocation?
💡 Explanation:Scarcity is the basic economic problem: the conflict between unlimited wants and limited resources. Because resources are scarce, choices must be made about how to allocate them, which forms the basis of economic study.

If the Marginal Propensity to Consume (MPC) is 0.8, what is the maximum potential change in equilibrium GDP from a $10 billion increase in government spending?
💡 Explanation:The formula for the spending multiplier (k) is $k = 1 / (1 - text{MPC})$. Given an MPC of 0.8, the multiplier is $k = 1 / (1 - 0.8) = 1 / 0.2 = 5$. The maximum potential change in GDP is calculated as $text{Change in GDP} = k times text{Change in Spending}$. Therefore, $text{Change in GDP} = 5 times $10 text{ billion} = $50 text{ billion}$. This represents the total effect of the initial injection plus the subsequent rounds of induced consumption.

What is the immediate effect of a central bank selling government bonds on money supply and interest rates?
💡 Explanation:Selling government bonds on the open market is a contractionary monetary policy action (Open Market Sales). When the central bank sells bonds, commercial banks use their reserves to purchase them, which effectively removes money from the banking system, thus reducing the money supply. A decrease in the money supply (or reserves) increases the cost of borrowing for banks, leading to a rise in market interest rates.

What does the short-run Phillips Curve primarily illustrate in macroeconomics?
💡 Explanation:The short-run Phillips Curve illustrates the inverse relationship, or trade-off, between the rate of inflation and the rate of unemployment in an economy. In the short run, policymakers can often reduce unemployment by stimulating aggregate demand, but this action tends to lead to higher inflation, and vice versa. This relationship breaks down in the long run as expectations adjust, but the short-run curve captures this immediate policy dilemma.
