7. Choose the correct statement(s) about the Phillips curve from the options below. (A) If inflation expectations rise, the short-run Phillips curve shifts right, so that at any inflation rate unemployment is higher in the short run than before.

8. Suppose that a country's currency depreciates significantly in the foreign exchange market. Which of the following outcome(s) are likely to result from this depreciation? (A) The country's exports become more competitive internationally, leading to an increase in aggregate demand and real GDP. (B) The overall price level in the country is likely to decrease as a result of the depreciation. (C) Foreign investors are more likely to invest in the country's assets due to the depreciation of the currency. (D) The depreciation may lead to inflationary pressures within the country as the cost of imported goods rises.
9. Choose the likely illustration(s) of the time inconsistency of policy among the follows. (A) A company decides to invest in new technology based on a long-term strategy to improve productivity. (B) When people expect that inflation will be low, it is harder for the Fed to increase output by increasing the money supply. (C) A government reduces taxes during a recession to stimulate the economy, following its long-term fiscal policy. (D) A central bank commits to a low inflation target but later increases the money supply to boost short-term employment before an election, leading to higher inflation.
10. Consider the open-economy macroeconomic model. Suppose a country experiences a significant increase in its government budget deficit. Which of the following outcome(s) are most likely to occur as a result? (A) The net capital outflow increases, leading to a depreciation of the country's currency. (B) The net capital outflow increases, leading to a depreciation of the country's currency. (C) The trade balance worsens due to a decrease in net exports. (D) The real interest rate rises, leading to a decrease in domestic investment.
11. A manufacturing firm produces gadgets and incurs fixed costs of $2000 and variable costs of $3000 for producing 100 units. The firm decides to increase production to 150 units, which increases the total variable costs to $4500. Choose the correct statement(s) about the firm's production costs from the following: (A) The average total cost per unit decreases as production increases from 100 to 150 units. (B) The average variable cost per unit remains constant as production increases from 100 to 150 units. (C) The total cost of producing 150 units is $6500. (D) The marginal cost of producing the 150th unit is $30.
12. Consider the concept of interest rate parity (IRP) for the association between interest rate differences and exchange rates. Which of the following statement(s) correctly illustrate the principle of interest rate parity? (A) If Country A's interest rate is 5% and Country B's interest rate is 3%, the forward exchange rate should predict a 2% depreciation of Country A's currency relative to Country B's currency. (B) If investors expect the currency of Country A to appreciate, the interest rate in Country A must be lower than in Country B to maintain interest rate parity. (C) Interest rate parity ensures that there are no arbitrage opportunities arising from differences in interest rates between two countries. (D) Interest rate parity implies that the difference in interest rates between two countries is equal to the expected change in exchange rates between their currencies.

一、問答申論和計算題(共 15 分)Consider a market where the demand function is \( Q_d = a - b \times P \) and the supply function is \( Q_s = k \times P \), with \( P \) representing the price, and \( Q_d \) and \( Q_s \) representing the quantity demanded and supplied, respectively. The parameters \( a \), \( b \), and \( k \) denote specific constants in the equations. If the government provides a subsidy of $1 per unit, calculate the deadweight loss. Is this loss greater, equal to, or less than the case if the government imposes an unit tax of $1 per unit? Why?
