Question 1

An economy's real exchange rate is best described as:

  • A) The nominal exchange rate unadjusted for inflation differentials
  • B) The nominal exchange rate adjusted for relative price levels between two countries, reflecting relative purchasing power
  • C) The exchange rate used only for interbank transactions
  • D) A fixed rate set permanently by international treaty
Show answer & explanation

Correct answer: B) The nominal exchange rate adjusted for relative price levels between two countries, reflecting relative purchasing power

The real exchange rate adjusts the nominal exchange rate for relative price levels (inflation) between two countries, providing a measure of relative purchasing power and international competitiveness.

Question 2

Under purchasing power parity (PPP), a country experiencing persistently higher inflation than its trading partners should, over the long run, see its currency:

  • A) Appreciate relative to its trading partners' currencies
  • B) Depreciate relative to its trading partners' currencies
  • C) Remain perfectly fixed regardless of inflation differentials
  • D) Become fully convertible automatically
Show answer & explanation

Correct answer: B) Depreciate relative to its trading partners' currencies

Relative purchasing power parity predicts that a country with persistently higher inflation than its trading partners will see its currency depreciate over the long run, offsetting the inflation differential and preserving purchasing power parity.

Question 3

A country pursuing an expansionary fiscal policy financed by increased government borrowing, combined with a central bank maintaining tight monetary policy, would most likely experience:

  • A) Lower interest rates and currency depreciation
  • B) Higher interest rates, which could attract foreign capital and put upward pressure on the currency (the classic policy-mix effect)
  • C) No effect on interest rates or the currency
  • D) An automatic reduction in the government's budget deficit
Show answer & explanation

Correct answer: B) Higher interest rates, which could attract foreign capital and put upward pressure on the currency (the classic policy-mix effect)

Expansionary fiscal policy combined with tight monetary policy tends to push interest rates higher, which can attract foreign capital inflows seeking higher yields, putting upward pressure on the domestic currency -- a classic policy-mix outcome.

Question 4

Which of the following is most likely to characterize an economy operating with a significant negative output gap (actual GDP below potential GDP)?

  • A) Rising inflationary pressure and an overheating labor market
  • B) Elevated unemployment and disinflationary or deflationary pressure
  • C) Guaranteed currency appreciation
  • D) A permanently balanced government budget
Show answer & explanation

Correct answer: B) Elevated unemployment and disinflationary or deflationary pressure

A negative output gap indicates the economy is producing below its potential, typically associated with elevated unemployment (slack in the labor market) and downward pressure on inflation.

Question 5

A regulator imposes a binding price ceiling below the market equilibrium price for a good. This is most likely to result in:

  • A) A surplus of the good
  • B) A shortage of the good, as quantity demanded exceeds quantity supplied at the ceiling price
  • C) No change in the quantity supplied or demanded
  • D) An automatic increase in the equilibrium price
Show answer & explanation

Correct answer: B) A shortage of the good, as quantity demanded exceeds quantity supplied at the ceiling price

A binding price ceiling set below the equilibrium price causes quantity demanded to exceed quantity supplied at that price, resulting in a shortage.

Question 6

In a Cournot oligopoly model, firms compete primarily by choosing:

  • A) Prices simultaneously
  • B) Output quantities simultaneously, with price determined by the market based on total output
  • C) Advertising budgets only
  • D) Product differentiation exclusively
Show answer & explanation

Correct answer: B) Output quantities simultaneously, with price determined by the market based on total output

In the Cournot model, oligopolists simultaneously choose output quantities (rather than prices), and the market price is then determined by the total industry output relative to demand.

Question 7

A small open economy pegs its currency to a major reserve currency. According to the "impossible trinity," this country cannot simultaneously also have:

  • A) A functioning central bank of any kind.
  • B) Any trade relationships with other countries.
  • C) A domestic currency in circulation.
  • D) Both free capital mobility and fully independent monetary policy.
Show answer & explanation

Correct answer: D) Both free capital mobility and fully independent monetary policy.

The impossible trinity holds that a country cannot simultaneously maintain a fixed exchange rate, free capital mobility, and independent monetary policy -- choosing a fixed peg means the country must sacrifice either free capital flows or independent monetary policy.

Question 8

Which of the following would most likely be associated with a country experiencing a persistent current account surplus?

  • A) The country has no foreign exchange reserves.
  • B) The country's currency must be depreciating continuously.
  • C) The country is a net lender to the rest of the world, exporting more than it imports.
  • D) The country must be experiencing hyperinflation.
Show answer & explanation

Correct answer: C) The country is a net lender to the rest of the world, exporting more than it imports.

A current account surplus means a country exports more (in goods, services, and income) than it imports, making it a net lender internationally, financed by a corresponding capital/financial account deficit (net capital outflows) as the accounting counterpart.

Question 9

A central bank credibly commits to an inflation-targeting framework. All else equal, this credibility is most likely to:

  • A) Eliminate the need for the central bank to take any policy actions.
  • B) Help anchor inflation expectations, potentially reducing the economic cost of achieving the inflation target.
  • C) Have no effect on inflation expectations whatsoever.
  • D) Guarantee inflation will always be exactly at the target with zero variance.
Show answer & explanation

Correct answer: B) Help anchor inflation expectations, potentially reducing the economic cost of achieving the inflation target.

A credible commitment to an inflation target can help anchor the public's and market participants' inflation expectations, which itself can reduce the real economic cost (such as unemployment) of achieving that target, since expectations influence wage- and price-setting behavior.

Question 10

Which of the following economic indicators would analysts typically classify as "coincident," changing roughly in tandem with overall economic activity?

  • A) Industrial production
  • B) Building permits issued
  • C) The average duration of unemployment
  • D) Stock market index levels
Show answer & explanation

Correct answer: A) Industrial production

Coincident indicators, such as industrial production or personal income, tend to move roughly in tandem with overall economic activity, providing a real-time read on the current state of the economy, as distinguished from leading indicators (which anticipate turns) and lagging indicators (which confirm turns after they occur).

Question 11

A government implements expansionary fiscal policy by increasing spending, financed by issuing additional government debt. Which of the following describes a potential "crowding out" effect of this policy?

  • A) Government spending always has no effect on private sector activity.
  • B) Crowding out refers exclusively to labor market effects, never to investment.
  • C) Crowding out guarantees an increase in private investment.
  • D) Increased government borrowing could raise interest rates, potentially reducing private investment spending.
Show answer & explanation

Correct answer: D) Increased government borrowing could raise interest rates, potentially reducing private investment spending.

Crowding out describes the phenomenon where increased government borrowing to finance higher spending can push up interest rates, potentially discouraging or displacing private investment spending that would have otherwise occurred, partially offsetting the intended stimulative effect of the fiscal expansion.

Question 12

Which of the following would most likely occur if a country's central bank unexpectedly raises its policy interest rate by more than markets had anticipated?

  • A) There would be no effect on the currency's exchange rate.
  • B) The move would automatically eliminate the country's trade deficit.
  • C) The domestic currency would likely appreciate, as higher relative interest rates tend to attract foreign capital inflows.
  • D) The domestic currency would definitely depreciate in all cases.
Show answer & explanation

Correct answer: C) The domestic currency would likely appreciate, as higher relative interest rates tend to attract foreign capital inflows.

An unexpectedly larger rate hike tends to make the country's assets relatively more attractive to yield-seeking foreign investors, increasing demand for the domestic currency and generally leading to appreciation, all else equal, consistent with interest rate parity intuition.

Question 13

A country's central bank pursues a monetary policy rule that adjusts the policy rate based on deviations of inflation from target and output from potential GDP. This type of rule-based framework is most closely associated with:

  • A) A purely fixed exchange rate regime with no independent monetary policy.
  • B) A commodity-backed currency standard, such as a gold standard.
  • C) A policy framework with no relationship to inflation or output.
  • D) A Taylor-rule-style approach to systematic monetary policy setting.
Show answer & explanation

Correct answer: D) A Taylor-rule-style approach to systematic monetary policy setting.

A Taylor-rule-style framework provides a systematic guideline for setting the policy interest rate based on the deviation of actual inflation from a target and the deviation of actual output from potential (an "output gap"), offering a more rules-based, transparent approach to monetary policy compared to purely discretionary decision-making.

Question 14

An analyst evaluating a country's capital market expectations examines its demographic trends and notes a rapidly aging population with a shrinking working-age share. This trend would most likely be viewed as:

  • A) A factor that automatically increases the country's productivity growth rate.
  • B) A headwind to long-run potential GDP growth, given the reduced growth contribution from labor force expansion, all else equal.
  • C) A guaranteed tailwind to long-run economic growth regardless of other factors.
  • D) A trend with no relevance to long-run capital market expectations.
Show answer & explanation

Correct answer: B) A headwind to long-run potential GDP growth, given the reduced growth contribution from labor force expansion, all else equal.

Long-run potential GDP growth is commonly modeled as a function of labor force growth and productivity growth; a rapidly aging population with a shrinking working-age share reduces the labor input contribution to growth, generally viewed as a headwind to long-run potential GDP, all else equal, an important consideration in long-term capital market expectations.

Question 15

Which of the following would most likely characterize an economy operating with a significant positive output gap (actual GDP above potential GDP)?

  • A) Deflation with falling prices across the economy.
  • B) A complete absence of any economic activity.
  • C) Rising inflationary pressures, as the economy operates above its sustainable long-run capacity.
  • D) Persistently high and rising unemployment.
Show answer & explanation

Correct answer: C) Rising inflationary pressures, as the economy operates above its sustainable long-run capacity.

A positive output gap, where actual output exceeds the economy's sustainable potential, is generally associated with rising inflationary pressure, as demand for resources (including labor) exceeds the economy's capacity to supply them without price pressures building, often prompting central banks to consider tightening monetary policy.

Question 16

A country's central bank engages in "sterilized" foreign exchange intervention, buying foreign currency to weaken its own currency while simultaneously conducting offsetting domestic open market operations. The purpose of the sterilization component is to:

  • A) Guarantee the intervention has no effect on the exchange rate at all.
  • B) Increase the domestic money supply as much as possible.
  • C) Eliminate the need for any further monetary policy actions.
  • D) Prevent the foreign exchange intervention from unintentionally changing the domestic money supply and interest rates.
Show answer & explanation

Correct answer: D) Prevent the foreign exchange intervention from unintentionally changing the domestic money supply and interest rates.

Sterilized intervention combines direct foreign exchange market intervention (to influence the exchange rate) with an offsetting domestic operation (such as selling government securities) specifically designed to neutralize the effect the FX intervention would otherwise have on the domestic money supply and interest rates, isolating the exchange rate effect from broader monetary conditions.

Question 17

Which of the following best describes the concept of "convergence" in the context of comparing economic growth across developing and developed economies?

  • A) The theory that developing economies, starting from a lower capital base, may grow faster than developed economies over time, potentially narrowing the gap in income levels, due to diminishing marginal returns to capital in more capital-rich economies.
  • B) A theory stating that all countries always have identical GDP growth rates at every point in time.
  • C) A theory that applies exclusively to currency exchange rates, not economic growth.
  • D) A guarantee that developing economies will always eventually surpass developed economies.
Show answer & explanation

Correct answer: A) The theory that developing economies, starting from a lower capital base, may grow faster than developed economies over time, potentially narrowing the gap in income levels, due to diminishing marginal returns to capital in more capital-rich economies.

Convergence theory suggests that developing economies with lower capital-to-labor ratios can experience higher marginal returns to capital investment, potentially allowing them to grow faster than more capital-rich developed economies and gradually narrow the income gap over time, though this convergence is not automatic or guaranteed and depends on various institutional and policy factors.

Question 18

Which of the following would most likely be a consequence of a country experiencing significant currency depreciation, from the perspective of its export sector, all else equal?

  • A) Currency depreciation has no effect on export competitiveness.
  • B) Export volumes always decrease following any currency depreciation.
  • C) Domestic exports become relatively cheaper for foreign buyers, potentially increasing export competitiveness and volume.
  • D) Domestic exports become relatively more expensive for foreign buyers.
Show answer & explanation

Correct answer: C) Domestic exports become relatively cheaper for foreign buyers, potentially increasing export competitiveness and volume.

A weaker domestic currency makes domestically produced goods cheaper for foreign buyers when priced in their own currency, generally improving export price competitiveness and potentially boosting export volumes, all else equal, though the actual effect also depends on demand elasticity and other factors.

Question 19

The Mundell-Fleming model predicts that under a fixed exchange rate regime, fiscal policy is:

  • A) Ineffective because it is crowded out by falling net exports
  • B) Highly effective because the central bank must expand money supply to maintain the peg
  • C) Ineffective because capital flows offset the stimulus
  • D) Highly effective because interest rates are free to rise, attracting capital
Show answer & explanation

Correct answer: B) Highly effective because the central bank must expand money supply to maintain the peg

Under fixed exchange rates with perfect capital mobility: fiscal expansion raises interest rates, attracting capital, causing appreciation pressure. To maintain the peg, the central bank must expand the money supply, amplifying the fiscal stimulus. Monetary policy is ineffective.

Question 20

An analyst observes that a country's current account has deteriorated as domestic saving has fallen relative to domestic investment. This is best explained by the:

  • A) Balance of payments identity: CA = Exports − Imports
  • B) Twin deficits hypothesis linking fiscal and trade deficits
  • C) Savings-investment identity: CA = S − I (national saving minus investment)
  • D) Purchasing power parity theory
Show answer & explanation

Correct answer: C) Savings-investment identity: CA = S − I (national saving minus investment)

The fundamental national accounts identity: CA = S − I. If saving falls or investment rises without a corresponding change in the other, the current account deteriorates. This is the macroeconomic interpretation of current account imbalances.

Question 21

A central bank targets nominal GDP rather than inflation. Compared to an inflation-targeting regime, this framework would most likely:

  • A) Result in less accommodation during supply shocks that raise both inflation and reduce output
  • B) Allow more accommodation when recessions coincide with low inflation
  • C) Produce a more stable price level in the long run
  • D) Require a higher policy rate when nominal GDP growth is driven entirely by real growth
Show answer & explanation

Correct answer: D) Require a higher policy rate when nominal GDP growth is driven entirely by real growth

Under NGDP targeting, the central bank tightens when nominal GDP (real growth + inflation) exceeds target, regardless of inflation alone. If real growth is high with low inflation, NGDP targeting would tighten more than a pure inflation-targeting framework.

Question 22

A country's labor productivity growth is 2.5% and the labor force grows at 1.5%. Under a neoclassical growth model, sustainable real GDP growth equals:

  • A) 1.0%
  • B) 2.5%
  • C) 4.0%
  • D) 1.5%
Show answer & explanation

Correct answer: C) 4.0%

In neoclassical growth theory, sustainable real GDP growth = labor productivity growth + labor force growth = 2.5% + 1.5% = 4.0%. Productivity growth allows each worker to produce more; labor force growth increases the number of workers.

Question 23

In the Taylor Rule, the central bank raises the policy rate above the neutral rate when:

  • A) Inflation is below target and the output gap is negative
  • B) Inflation is above target and/or the output gap is positive
  • C) The unemployment rate rises above the natural rate
  • D) The currency is depreciating rapidly
Show answer & explanation

Correct answer: B) Inflation is above target and/or the output gap is positive

Taylor Rule: i = r* + π + 0.5(π−π*) + 0.5(y−y*). The policy rate rises above neutral when inflation exceeds target (π>π*) or when actual output exceeds potential (positive output gap), signaling overheating.

Question 24

The uncovered interest rate parity (UIP) condition implies that a currency with higher nominal interest rates should:

  • A) Appreciate to offset the return differential
  • B) Depreciate over time to offset the higher interest income for foreign investors
  • C) Remain unchanged because interest differentials are irrelevant to spot rates
  • D) Appreciate if its current account is in surplus
Show answer & explanation

Correct answer: B) Depreciate over time to offset the higher interest income for foreign investors

UIP: expected exchange rate change = interest rate differential. A currency with higher rates is expected to depreciate by exactly the interest differential, leaving foreign investors indifferent between investing domestically or abroad.

Question 25

In a small open economy with a fixed exchange rate and free capital mobility, according to the Mundell-Fleming model, domestic monetary policy is generally:

  • A) Guaranteed to eliminate the country's trade deficit immediately.
  • B) Ineffective at influencing the domestic economy, since capital flows will offset attempts to change domestic interest rates relative to world rates.
  • C) Highly effective and entirely independent of exchange rate considerations.
  • D) The only effective policy tool available to the government.
Show answer & explanation

Correct answer: B) Ineffective at influencing the domestic economy, since capital flows will offset attempts to change domestic interest rates relative to world rates.

Under the Mundell-Fleming "impossible trinity" framework, a country cannot simultaneously maintain a fixed exchange rate, free capital mobility, and independent monetary policy; with a fixed rate and open capital markets, monetary policy loses its effectiveness as capital flows neutralize attempts to alter domestic interest rates relative to world rates.

Question 26

A country's current account balance is closely linked to its capital and financial account balance because:

  • A) Under the balance of payments framework, the current account and the capital/financial account (plus reserve changes) must sum to approximately zero, reflecting an accounting identity.
  • B) The two accounts are entirely unrelated to one another by construction.
  • C) A current account surplus always causes a capital account surplus of equal size, driven by a separate causal mechanism.
  • D) Only developing countries are subject to this relationship.
Show answer & explanation

Correct answer: A) Under the balance of payments framework, the current account and the capital/financial account (plus reserve changes) must sum to approximately zero, reflecting an accounting identity.

The balance of payments accounting identity means that a current account deficit must be financed by a corresponding capital/financial account surplus (net capital inflows), and vice versa, reflecting how a country's trade and income flows are financed through cross-border capital flows.

Question 27

A firm operating in an oligopolistic market with only a few dominant competitors is most likely to exhibit which of the following characteristics, relative to a firm in a perfectly competitive market?

  • A) No ability whatsoever to influence market price.
  • B) Complete price-taking behavior identical to perfect competition.
  • C) Guaranteed collusion with all competitors under all circumstances.
  • D) Greater ability to influence price and significant strategic interdependence with rival firms' pricing and output decisions.
Show answer & explanation

Correct answer: D) Greater ability to influence price and significant strategic interdependence with rival firms' pricing and output decisions.

Firms in an oligopoly, unlike price-taking firms in perfect competition, generally have some ability to influence price and must strategically consider how rivals will respond to their pricing and output decisions, a dynamic known as strategic interdependence.

Question 28

An economy experiencing "stagflation" is characterized by:

  • A) Deflation combined with zero unemployment.
  • B) A condition that can always be resolved simply by increasing the money supply.
  • C) Simultaneously high inflation and high unemployment (or stagnant economic growth), a combination that complicates standard monetary policy responses.
  • D) Low inflation combined with rapid economic growth.
Show answer & explanation

Correct answer: C) Simultaneously high inflation and high unemployment (or stagnant economic growth), a combination that complicates standard monetary policy responses.

Stagflation refers to the unusual and difficult combination of high inflation alongside high unemployment or stagnant growth, a scenario that complicates monetary policy since measures to fight inflation (raising rates) can worsen unemployment, and vice versa.

Question 29

Purchasing power parity (PPP) theory suggests that, over the long run, exchange rates between two countries should adjust so that:

  • A) Trade between the two countries will cease entirely.
  • B) Identical baskets of goods cost approximately the same amount when expressed in a common currency across both countries.
  • C) One country's currency will always eventually become worthless.
  • D) Interest rates in both countries must be identical at all times.
Show answer & explanation

Correct answer: B) Identical baskets of goods cost approximately the same amount when expressed in a common currency across both countries.

Purchasing power parity theory holds that, in the long run, exchange rates should adjust toward the level at which an identical basket of goods costs the same amount in both countries when converted to a common currency, eliminating persistent arbitrage opportunities in goods prices across borders.

Question 30

A central bank pursuing an inflation-targeting monetary policy framework primarily commits to:

  • A) Adjusting policy tools, such as interest rates, with the explicit goal of achieving a publicly stated inflation rate target over time.
  • B) Fixing the exchange rate permanently against a single foreign currency.
  • C) Eliminating all government debt within five years.
  • D) Guaranteeing zero unemployment as its primary mandate.
Show answer & explanation

Correct answer: A) Adjusting policy tools, such as interest rates, with the explicit goal of achieving a publicly stated inflation rate target over time.

Inflation targeting is a monetary policy framework in which a central bank publicly commits to a specific inflation target (or range) and adjusts its policy tools to achieve that target over a defined time horizon, intended to help anchor inflation expectations.

Question 31

The current spot exchange rate is USD 1.1000 per EUR. The one-year risk-free rate is 5.0% in USD and 3.0% in EUR. Assuming covered interest rate parity holds, the theoretically correct one-year forward rate (USD per EUR) is closest to:

  • A) 1.0791, which incorrectly inverts the interest rate ratio as (1 + r_EUR) / (1 + r_USD) rather than applying it in the correct direction for USD-per-EUR quotes.
  • B) 1.1214, calculated as Forward = Spot x (1 + r_USD) / (1 + r_EUR) = 1.1000 x (1.05 / 1.03) = 1.1000 x 1.019417 = 1.1214, meaning the euro trades at a forward premium in USD terms consistent with its lower interest rate.
  • C) 1.1000, which incorrectly assumes the forward rate must always equal the spot rate regardless of any interest rate differential between the two currencies.
  • D) 1.1330, which incorrectly adds the two interest rates together (1.05 + 1.03 relative adjustment) rather than correctly taking their ratio.
Show answer & explanation

Correct answer: B) 1.1214, calculated as Forward = Spot x (1 + r_USD) / (1 + r_EUR) = 1.1000 x (1.05 / 1.03) = 1.1000 x 1.019417 = 1.1214, meaning the euro trades at a forward premium in USD terms consistent with its lower interest rate.

Covered interest rate parity: F = S x (1 + r_domestic)/(1 + r_foreign), where the domestic currency is USD (the currency the rate is quoted in) and the foreign currency is EUR. F = 1.1000 x (1.05/1.03) = 1.1000 x 1.019417 = 1.12136, or approximately 1.1214. The higher-interest-rate currency (USD) trades at a forward discount relative to itself, equivalently the lower-rate currency (EUR) trades at a forward premium, consistent with no-arbitrage.

Question 32

A regulator is evaluating a proposed new financial market regulation. Economic analysis of regulation generally suggests that a well-designed cost-benefit evaluation of such a proposal should most importantly:

  • A) Assume that any regulation addressing a genuine market failure is automatically net-beneficial to society and therefore requires no further cost-benefit analysis.
  • B) Focus exclusively on the regulator's own implementation and enforcement budget, while disregarding all costs borne by regulated firms and market participants.
  • C) Compare the expected costs of the regulation (including compliance costs, reduced market efficiency or liquidity, and unintended consequences) against its expected benefits (such as reduced systemic risk or improved market integrity), rather than assuming any regulation intended to address a market failure is automatically net-beneficial.
  • D) Focus exclusively on maximizing the stringency of the regulation, since more stringent regulation is always superior to less stringent regulation regardless of the specific costs involved.
Show answer & explanation

Correct answer: C) Compare the expected costs of the regulation (including compliance costs, reduced market efficiency or liquidity, and unintended consequences) against its expected benefits (such as reduced systemic risk or improved market integrity), rather than assuming any regulation intended to address a market failure is automatically net-beneficial.

Sound regulatory economic analysis weighs the actual expected costs (direct compliance costs, potential reductions in market efficiency/liquidity/innovation, unintended consequences, and regulatory burden) against expected benefits, rather than assuming that regulation addressing a market failure is automatically net-beneficial regardless of its costs -- both over- and under-regulation carry economic costs.

Question 33

A country's central bank pursues a tight (contractionary) monetary policy while its fiscal authority simultaneously pursues an expansionary (loose) fiscal policy involving substantial deficit-financed government spending. Under the Mundell-Fleming framework with high capital mobility, this policy mix is most likely to result in:

  • A) Currency depreciation, since tight monetary policy is assumed under this framework to always reduce, rather than increase, capital inflows regardless of the resulting interest rate differential.
  • B) Higher domestic interest rates attracting capital inflows, leading to currency appreciation, alongside a boost to aggregate demand from the expansionary fiscal spending -- with the interest-sensitive, currency-sensitive sectors (such as exports) most negatively affected by the appreciation.
  • C) No effect whatsoever on the exchange rate, since monetary and fiscal policy are assumed under this framework to operate through entirely independent, non-interacting channels.
  • D) A guaranteed recession, since this specific combination of tight monetary and loose fiscal policy is assumed under this framework to always produce a net contractionary effect on the economy.
Show answer & explanation

Correct answer: B) Higher domestic interest rates attracting capital inflows, leading to currency appreciation, alongside a boost to aggregate demand from the expansionary fiscal spending -- with the interest-sensitive, currency-sensitive sectors (such as exports) most negatively affected by the appreciation.

Under Mundell-Fleming with high capital mobility, tight monetary policy raises domestic interest rates, attracting foreign capital and appreciating the currency; expansionary fiscal policy independently boosts aggregate demand. Combined, this mix tends to produce currency appreciation (hurting net exports) alongside demand support from fiscal spending, a policy mix historically associated with widening trade deficits in economies pursuing it.

Question 34

During the contraction phase of a business cycle, which of the following combinations of indicator behavior would most likely be classified as consistent with standard leading economic indicator patterns, ahead of an eventual trough?

  • A) A rising inventory-to-sales ratio alongside a declining average workweek and weakening new orders for durable goods, since these forward-looking measures of production and labor adjustment typically deteriorate before broader economic activity troughs and later recovers.
  • B) A declining unemployment rate combined with rising capacity utilization, both of which are typically classified as lagging or coincident, not leading, indicators of economic activity.
  • C) Rising corporate profits reported in the most recent quarter, which is generally considered a coincident-to-lagging indicator reflecting activity that has already occurred rather than a forward-looking signal.
  • D) An increase in commercial and industrial loans outstanding, which is generally classified as a lagging indicator since borrowing activity typically responds to conditions after they have already changed.
Show answer & explanation

Correct answer: A) A rising inventory-to-sales ratio alongside a declining average workweek and weakening new orders for durable goods, since these forward-looking measures of production and labor adjustment typically deteriorate before broader economic activity troughs and later recovers.

Leading indicators (such as the inventory-to-sales ratio, average workweek, new orders, and the yield curve slope) tend to shift before overall economic activity turns. Unemployment rate and capacity utilization are typically coincident/lagging, corporate profits are typically lagging, and outstanding loan balances are also typically lagging, since they reflect decisions and activity that already occurred.

Question 35

An economy's aggregate production function is Cobb-Douglas with a capital share of output (alpha) equal to 0.30. Total factor productivity (TFP) growth is estimated at 1.5% per year, capital stock is growing at 4.0% per year, and labor input is growing at 1.0% per year. Using growth accounting, the economy's estimated potential (trend) GDP growth rate is closest to:

  • A) 6.5%, which incorrectly simply sums TFP growth, capital growth, and labor growth without weighting capital and labor growth by their respective Cobb-Douglas output shares.
  • B) 1.5%, which incorrectly ignores the contributions of capital and labor growth entirely and reflects only the TFP growth component.
  • C) 2.65%, which incorrectly applies the capital share weight to labor growth and the labor share weight to capital growth (reversing the two weights).
  • D) 3.4%, calculated as potential GDP growth = TFP growth + (alpha x capital growth) + [(1 - alpha) x labor growth] = 1.5% + (0.30 x 4.0%) + (0.70 x 1.0%) = 1.5% + 1.2% + 0.7% = 3.4%.
Show answer & explanation

Correct answer: D) 3.4%, calculated as potential GDP growth = TFP growth + (alpha x capital growth) + [(1 - alpha) x labor growth] = 1.5% + (0.30 x 4.0%) + (0.70 x 1.0%) = 1.5% + 1.2% + 0.7% = 3.4%.

Growth accounting decomposes potential GDP growth as: g(Y) = g(TFP) + alpha x g(K) + (1 - alpha) x g(L). Substituting: 1.5% + (0.30 x 4.0%) + (0.70 x 1.0%) = 1.5% + 1.2% + 0.7% = 3.4%.

Question 36

An analyst observes that a currency's forward rate consistently differs from the market's actual subsequent realized future spot rate, even though covered interest rate parity holds precisely at all times in the market (no covered arbitrage opportunity exists). This is most likely best explained by:

  • A) A violation of covered interest rate parity, which by definition must be the cause any time the forward rate differs from the realized future spot rate.
  • B) An error in the calculation of the spot exchange rate, since forward and realized spot rates must always be identical in a well-functioning market.
  • C) The existence of a time-varying foreign exchange risk premium (or other factors such as risk aversion and market segmentation) causing uncovered interest rate parity to not hold precisely, even while covered interest rate parity -- which is enforced by pure arbitrage and involves no exchange rate risk -- holds continuously.
  • D) The complete irrelevance of interest rate differentials to exchange rate determination in all circumstances.
Show answer & explanation

Correct answer: C) The existence of a time-varying foreign exchange risk premium (or other factors such as risk aversion and market segmentation) causing uncovered interest rate parity to not hold precisely, even while covered interest rate parity -- which is enforced by pure arbitrage and involves no exchange rate risk -- holds continuously.

Covered interest rate parity is enforced by pure arbitrage (no exchange rate risk) and holds essentially continuously. Uncovered interest rate parity -- the proposition that the forward rate is an unbiased predictor of the future spot rate -- depends additionally on risk-neutral expectations and often does not hold well empirically due to time-varying currency risk premiums and other frictions, even while covered parity holds.
