Phases of the business cycle — MCQs

Bellaria is a small open economy whose central bank maintains a credible fixed exchange rate against the currency of its largest trading partner. Capital is highly mobile, and there are no material capital controls. To maintain the peg, the central bank buys or sells foreign reserves when private transactions place pressure on the exchange rate. Any foreign-exchange intervention described in the case is unsterilized unless otherwise stated. A sovereign analyst reviews Bellaria's latest data in Exhibit 1. Household consumption has weakened, manufacturing inventories have increased unexpectedly, and surveyed firms report declining new orders. Wage growth has slowed, and the increase in unemployment is concentrated in cyclically sensitive industries. The analyst does not identify a material adverse supply shock. Potential output continues to increase slowly, so the increasingly negative output gap primarily reflects weak aggregate demand. The finance ministry is considering the package in Exhibit 2. Both measures would take effect immediately and last for one year. The estimated multipliers already reflect the economy's marginal propensity to consume, import leakage, and the relevant tax effects. The increase in taxes is a newly legislated measure rather than a consequence of existing tax rules. The ministry is also allowing unemployment-benefit payments to increase under existing eligibility formulas and expects income-tax receipts to decline as household income falls. Neither of these latter changes requires new legislation. The central bank is separately considering a reduction in its policy interest rate. The governor observes that inflation is below target and the policy rate exceeds the rate that would otherwise be consistent with the current weak economy. A staff economist cautions that, with high capital mobility and a credible fixed exchange rate, a unilateral reduction in the domestic interest rate would trigger capital outflows and downward pressure on the currency. To preserve the peg, the central bank would need to sell foreign reserves and purchase domestic currency. This intervention would remove domestic liquidity unless it were sterilized. For purposes of the analysis, fiscal financing does not immediately increase sovereign risk premiums, Bellaria has sufficient foreign reserves to defend the peg, and foreign policy rates remain unchanged. The questions concern near-term aggregate-demand effects; they do not require an assessment of long-run debt sustainability or long-run monetary neutrality.

Meridian Sovereign Strategy Fund invests in the government bonds and listed infrastructure companies of Republic A and Republic B. The portfolio team is evaluating trade patterns, long-run growth prospects, and geopolitical risks before revising its country allocations. Each country has a fixed labor endowment, and labor is the only production input used in the trade analysis. Labor is fully mobile between industries within each country but cannot move between countries. Unit labor requirements are constant, transportation costs are ignored, and competitive markets prevail before any trade restriction is imposed. Republic A can produce both wheat and machines with fewer labor hours than Republic B. The chief economist cautions that this fact alone does not determine the direction of specialization because the relevant framework compares opportunity costs. The investment team therefore uses the production data in Exhibit 1 to identify each country's comparative advantage. Republic A subsequently introduces an import tariff on machines. It is a price taker in world markets, and the tariff does not change the price received by foreign exporters. Domestic consumers pay the world price plus the tariff. Domestic machine production increases, machine consumption decreases, and the government receives the tariff revenue. The team must evaluate the national welfare effect rather than focusing only on producers or government revenue. Republic B has lower capital per worker but a higher investment rate and faster real GDP per capita growth. The two countries have comparable access to technology, and the team assumes similar institutional quality for its conditional-convergence assessment. Republic B also relies heavily on imported energy passing through a narrow shipping corridor. A neighboring state has threatened to interrupt access, although no physical disruption has yet occurred. Finally, Republic B proposes a debt-financed fiscal expansion while its economy is operating at full employment. The central bank is independent and will not increase the money supply to accommodate the fiscal measure. The portfolio team recognizes that the likely effects of this proposal differ from those of fiscal stimulus undertaken during a recession with idle productive capacity. Relevant quantitative and policy facts are presented in Exhibits 1 and 2.

Northbridge Asset Management is reviewing the international exposures of its global balanced portfolio. The portfolio holds shares of domestic steel users, multinational shipping firms, and commodity producers, as well as sovereign bonds issued by countries that depend heavily on imported industrial materials. A small, open economy represented in the portfolio has introduced a specific tariff on imported steel. The country cannot influence the world steel price, and transportation costs are negligible. Exhibit 1 provides the relevant tariff and import data. The government is also considering replacing the tariff with an import quota equal to the current post-tariff level of imports. Under the proposed quota, licenses would be granted without charge to foreign producers, allowing them to retain any quota rents. The research team expects domestic steel demand to become more volatile because of a planned infrastructure program. The team also reviews the geopolitical developments summarized in Exhibit 2. Portfolio manager David Okafor notes that the fund has limited direct investment in the affected commodity-exporting state. Risk analyst Priya Shah responds that the fund may nevertheless face indirect exposure through issuers' input costs, shipping routes, bank counterparties, and compliance with potential sanctions. She proposes mapping these transmission channels and evaluating multiple scenarios rather than relying on a single probability-weighted forecast. Finally, the team examines the small open economy's external accounts. The current account balance, official reserve transactions, and statistical discrepancy are reported in Exhibit 1. For this analysis, the term capital account includes the financial account, consistent with the simplified curriculum presentation of international capital flows. A capital account surplus represents a net financial inflow from foreign investors, whereas a capital account deficit represents a net financial outflow. Each analysis is performed independently. The tariff revenue calculation uses only the actual post-tariff import quantity. The tariff-versus-quota comparison assumes both policies initially restrict imports to the same quantity, and the external-account analysis assumes all entries are measured over the same annual period.

An analyst observes many firms, differentiated products, unrestricted entry, and zero economic profit in long-run equilibrium. The market structure is most likely:

Alton Foods produces branded snack products in a market containing many competing sellers. Each seller offers a differentiated product, and advertising, packaging, and customer preferences prevent the products from being perfect substitutes. Entry is legally unrestricted, although a new producer must incur initial marketing expenses. Alton faces a downward-sloping demand curve and selects output to maximize economic profit. Its analysts assume that output can be adjusted in the increments shown in Exhibit 1 and that fixed costs do not affect the marginal output decision. Alton currently earns positive economic profit. Management expects this performance to attract new firms, which will offer close substitutes and reduce the quantity demanded from Alton at each price. An analyst states that, after entry has fully adjusted, Alton will necessarily charge a price equal to marginal cost. A second analyst argues that entry instead eliminates economic profit while product differentiation can preserve a price above marginal cost. Alton imports an agricultural input from Meridia. Meridia is a small country in the world market for that input, so changes in its import demand do not affect the world price. To protect domestic producers, Meridia imposes a tariff of USD 20 per imported unit. Exhibit 2 shows annual quantities before and after the tariff. The tariff is collected by Meridia's government, there are no administrative costs, and no foreign exporter changes its pre-tariff price. The team's welfare analysis therefore treats the tariff revenue as a domestic transfer rather than a net social loss. A separate geopolitical dispute could affect Alton's packaging equipment. The government of Meridia controls exports of advanced manufacturing sensors produced by domestic companies. It threatens to deny those sensors to the neighboring state of Torven unless Torven changes its maritime policy. Meridia has not deployed military forces, and the proposed restriction is intended to impose economic costs sufficient to alter Torven's behavior. The investment team must classify the instrument because economic coercion, military conflict, and cooperative diplomacy have different implications for the probability and transmission of geopolitical risk. The four questions independently assess Alton's output decision, its long-run market equilibrium, the tariff's welfare cost, and Meridia's geopolitical instrument.

A government sets a 2% inflation target, while the central bank independently chooses the policy instruments used to achieve it. The bank most likely has:

A country strengthens property rights, contract enforcement, and competitive entry while capital and labor growth remain unchanged. Its higher sustainable growth will most likely arise from:
