    a.
    A downsloping aggregate demand curve can be explained by the interest-rate effect, the real-balances effect, and the foreign purchases effect.
    b.
    The explanation for a downsloping aggregate demand curve differs from the explanation for a single product because:
    A downsloping aggregate demand curve assumes constant money income, so substitution toward a now relatively cheaper product for those whose prices have risen does not occur.
    A downsloping aggregate demand curve reflects changes in the overall price level rather than relative prices among individual goods, so the usual single‑product substitution effect is not the primary explanation.
    A downsloping single‑product demand curve assumes other prices and income are held constant, so consumers substitute toward a relatively cheaper product when its price falls.
    The single‑product demand curve relies on relative price changes among goods, whereas the aggregate demand curve reflects economy‑wide price level changes and their effects on aggregate spending.
    c.
    The multiplier:
    causes an initial change in spending to generate an equal change in saving.
    equalizes the change in spending and the change in aggregate demand.
    causes an initial change in spending to generate an even larger change in the aggregate demand.
    reduces the impact of spending changes on the aggregate demand curve.

    Total profit is highest when the recycling production method is used.
    When the chemical plant uses the recycling method, the hiking lodge earns $1,800−$1,000=$800 more per week than it does with no recycling. Therefore, the hiking lodge should be willing to pay up to $800 per week for the chemical plant to recycle water. However, the recycling method decreases the chemical plant’s profit by $2,000−$1,500=$500 per week. Therefore, the chemical plant should be willing to use the recycling method if it is compensated with at least $500 per week.
    Suppose the hiking lodge has the property rights to the river. That is, the hiking lodge has the right to a clean (unpolluted) river. In this case, assuming the two firms can bargain at no cost, the chemical plant will not use the recycling method and will pay the hiking lodge between $500 and $800 per week.
    Now, suppose the chemical plant has the property rights to the river, including the right to pollute it. In this case, assuming the two firms can bargain at no cost, the chemical plant will use the recycling method, and the hiking lodge will pay the chemical plant between $500 and $800 per week.
    The chemical plant will make the most profit when it has property rights to pollute the river.
    True or False: The chemical plant will use the recycling method, regardless of who has the property rights.
    True
    False

    Based on the case study
    Inside the Fed: The Fed’s New Monetary Policy Strategy
    , the Federal Reserve adopted Average Inflation Targeting (AIT) in August 2020, a strategy in which the Fed seeks to achieve 2% inflation on average over time rather than each year, allowing temporary overshoots or undershoots to offset past deviations.
    Suppose the U.S. economy experiences three consecutive years of 1.2% inflation, followed by a supply-driven rebound. Under the Fed’s pre-2020 monetary policy framework, it would continue aiming for 2% inflation regardless of past outcomes. Under the new AIT strategy, how would the Fed’s likely response differ, and what are the theoretical implications for inflation expectations and real interest rates?
    Possible interpretations of the Fed’s likely response and implications:
    The Fed could tighten monetary policy during the recovery to preempt potential overshooting, demonstrating long-term credibility and keeping inflation expectations anchored near 2%.
    The Fed could maintain a strict 2% inflation ceiling regardless of past outcomes, which would raise the real interest rate during recovery and aim to keep inflation expectations static.
    Alternatively, under AIT the Fed could tolerate inflation above 2% temporarily to offset prior undershoots. This approach could raise inflation expectations, reduce the real ex‑ante interest rate (for a given nominal rate), and reinforce automatic stabilization even if nominal rates remain unchanged.

    A large multinational bank, GlobalCore Bank, operates through subsidiaries and branches in over 50 countries. Its parent company is chartered in Country x, a relatively small jurisdiction with limited regulatory capacity. GlobalCore engages in high-risk structured finance activities through subsidiaries in Countries Y and Z. Suppose a regulatory concem arises about the lack of consktent oversight.
    Based on lessons from the BCCI collapse and principles from the Basel Committee’s international regulatory framework, which of the following responses would most directly address the core regulatory vulnerability presented by GlobalCore Bank?
    GlobalCore Bank should be placed under the authority of a single, well-resourced home-country regulator in Country X with power to obtain full information on global activities, while host countries retain rights to limit operations if oversight is deemed insufficient
    Country x should delegate oversight responsibility to a supranutional body such as the IMF to avoid confficts of interest and ensure impartial supervision.
    Country Y and Z should independently enforce their domestic regulations and require GlobalCore’s subsidaries to report all structured finance activities locally, bypassing Country Xs oversight.
    Country X should require GlobalCore to split into regionaly independent banks, each supervised by its host country. to eliminate the complexities of multinational supervition.

    The following model can be used to study whether campaign expenditures affect election outcomes:
    voteA = β0 + β1 log(expendA) + β2 log(expendB) + β3 prtystrA + u
    where voteA is the percentage of the vote received by Candidate A, expendA and expendB are campaign expenditures by Candidates A and B respectively, and prtystrA is a measure of the party strength for Candidate A (the percentage of the most recent presidential vote that went to Candidate A’s party).
    (i) True or False: If Candidate A’s expenditures increase by one percent, voteA will increase by approximately β1 percentage points.
    True    False
    (ii) True or False: In terms of the parameters, the null hypothesis that a 1% increase in Candidate A’s expenditures is offset by a 1% increase in Candidate B’s expenditures is: H0: β1 = −β2.
    True    False
    (iii) Use OLS to estimate the following model: voteA = β0 + β1 log(expendA) + β2 log(expendB) + β3 prtystrA + u.
    The estimated equation is: voteA^ = + log(expendA) + log(expendB) + prtystrA.
    True or False: As both the coefficient on log(expendA) and the coefficient on log(expendB) are statistically significant (at the 1% significance level), campaign expenditures by Candidates A and B have an effect on the percentage of the vote received by Candidate A.
    True    False
