Question 1Scarcity, markets and consumer decisions

Opportunity cost is best defined as:

  1. the accounting cost of materials recorded in the ledger
  2. the total money spent on the chosen option
  3. the value of the next-best alternative forgone when a choice is made Correct answer.
  4. any tax paid to the government on a purchase

Explanation

Opportunity cost measures the next-best alternative given up. In BW Wirtschaft, this concept underpins household, firm, and policy decisions.

Question 2Scarcity, markets and consumer decisions

A student spends Saturday studying for Wirtschaft instead of working a paid shift that would have earned EUR 80. What is the opportunity cost of studying?

  1. EUR 0, because studying builds human capital
  2. EUR 80 of forgone wages from the shift Correct answer.
  3. the price of the textbook only
  4. the school's tuition fee for the year

Explanation

By studying, the student forgoes the next-best alternative-the EUR 80 wage. That forgone wage is the opportunity cost of the study decision (ignoring other non-wage benefits for this item).

Question 3Scarcity, markets and consumer decisions

In the standard market model, an increase in demand (shift right), with supply unchanged, typically leads to:

  1. a lower equilibrium price and lower equilibrium quantity
  2. a higher equilibrium price and higher equilibrium quantity Correct answer.
  3. a higher equilibrium price and lower equilibrium quantity
  4. no change in price or quantity

Explanation

A rightward demand shift raises willingness to pay at each quantity. With upward-sloping supply, the new intersection has a higher price and higher quantity.

Question 4Scarcity, markets and consumer decisions

Ceteris paribus, which event most clearly shifts the supply curve of bread to the left?

  1. a fall in the price of bread
  2. a rise in consumer incomes when bread is a normal good
  3. a sharp rise in the price of flour used by bakeries Correct answer.
  4. a successful advertising campaign for bread

Explanation

Higher flour prices raise marginal costs of baking, so less bread is supplied at each bread price-a leftward supply shift. Price of bread itself is a movement along supply; income/ads affect demand.

Question 5Scarcity, markets and consumer decisions

Price elasticity of demand measures:

  1. how much quantity supplied responds to a change in input prices
  2. the percentage change in quantity demanded divided by the percentage change in price Correct answer.
  3. the absolute change in quantity demanded when income rises by one euro
  4. the slope of the production possibility frontier

Explanation

Own-price elasticity of demand is (%ΔQd)/(%ΔP). Absolute values above 1 indicate elastic demand; below 1 inelastic (with the usual caveats about signs).

Question 6Scarcity, markets and consumer decisions

When the price of a ticket rises from EUR 20 to EUR 24 and quantity demanded falls from 500 to 400, the arc (midpoint) price elasticity of demand is closest to:

  1. 0.5 (inelastic)
  2. 1.0 (unit elastic)
  3. 1.22 (elastic) Correct answer.
  4. 2.5 (highly elastic)

Explanation

Midpoint method: %ΔQ = (400−500)/((400+500)/2) = −100/450 ≈ −22.22%. %ΔP = (24−20)/((24+20)/2) = 4/22 ≈ 18.18%. Elasticity ≈ 22.22/18.18 ≈ 1.22 (elastic).

Question 7Scarcity, markets and consumer decisions

A good has price elasticity of demand of 0.4. If the firm raises price slightly, total revenue will most likely:

  1. fall, because demand is elastic
  2. rise, because demand is inelastic Correct answer.
  3. stay exactly the same in all cases
  4. rise only if supply is perfectly inelastic

Explanation

When |Ed| < 1, demand is inelastic: percentage quantity falls less than percentage price rises, so total revenue (P×Q) increases with a small price rise.

Question 8Scarcity, markets and consumer decisions

Which situation best illustrates a negative externality?

  1. a vaccination that also protects unvaccinated neighbors
  2. a factory emitting pollution that harms nearby residents without compensation Correct answer.
  3. a pure public good such as national defense
  4. perfectly competitive pricing equal to marginal cost

Explanation

Negative externalities impose uncompensated costs on third parties. Pollution is the classic case; markets then overproduce relative to the social optimum unless internalized.

Question 9Scarcity, markets and consumer decisions

The Magisches Viereck of German economic policy traditionally includes which four goals?

  1. price stability, high employment, external balance, and steady/adequate growth Correct answer.
  2. maximum tariffs, zero immigration, fixed money supply, and budget surplus forever
  3. only inflation targeting and nothing else
  4. stock-market highs, low taxes only, gold standard, and autarky

Explanation

The Stability and Growth Act tradition frames price-level stability, high employment, external balance, and steady/adequate growth-the Magisches Viereck. Conflicts among goals create the 'magic' trade-off problem later extended toward ecological goals.

Question 10Scarcity, markets and consumer decisions

Real GDP differs from nominal GDP because real GDP:

  1. includes intermediate goods twice
  2. adjusts for price-level changes using constant prices or a deflator Correct answer.
  3. excludes government spending by definition
  4. is always larger than nominal GDP

Explanation

Real GDP holds prices constant (or deflates nominal GDP) to isolate volume changes. Nominal GDP mixes price and quantity movements.

Question 11Scarcity, markets and consumer decisions

Nominal GDP rises from EUR 400 bn to EUR 440 bn while the GDP deflator rises from 100 to 110. Real GDP (base = deflator 100) is closest to:

  1. EUR 360 bn
  2. EUR 400 bn Correct answer.
  3. EUR 440 bn
  4. EUR 484 bn

Explanation

Real GDP ≈ nominal / (deflator/100) = 440 / 1.10 = EUR 400 bn. All of the nominal increase is explained by prices; real output is unchanged.

Question 12Scarcity, markets and consumer decisions

A demand-side fiscal stimulus that raises government spending is most directly intended to:

  1. reduce aggregate demand during a boom
  2. increase aggregate demand when there is spare capacity Correct answer.
  3. set all relative prices by central plan
  4. eliminate structural mismatch unemployment overnight

Explanation

Demand-oriented policy boosts spending to raise aggregate demand-especially relevant when the economy is below capacity. It does not automatically fix structural mismatch.

Question 13Scarcity, markets and consumer decisions

If the consumer price index (CPI) rises from 120 to 126 over one year, the inflation rate is:

  1. 5% Correct answer.
  2. 6%
  3. 26%
  4. 120%

Explanation

Inflation rate = (126−120)/120 = 6/120 = 5%. Always divide the change by the initial index level.

Question 14Scarcity, markets and consumer decisions

Which statement about a binding minimum price (price floor) above equilibrium is correct?

  1. it creates a shortage because quantity demanded exceeds quantity supplied
  2. it creates a surplus because quantity supplied exceeds quantity demanded Correct answer.
  3. it has no effect because markets ignore legal prices
  4. it always maximizes consumer surplus

Explanation

A price floor above equilibrium keeps price high, so Qs > Qd and a surplus appears (classic agricultural or wage-floor logic when binding).

Question 15Scarcity, markets and consumer decisions

Graph interpretation: At price EUR 10, quantity demanded is 80 and quantity supplied is 50. This market shows:

  1. equilibrium
  2. a surplus of 30 units
  3. a shortage of 30 units Correct answer.
  4. perfectly elastic supply

Explanation

Qd (80) > Qs (50) ⇒ excess demand / shortage of 30. Price pressure is upward toward equilibrium.

Question 16Scarcity, markets and consumer decisions

A leftward shift of labor demand in a competitive labor market, with labor supply unchanged, tends to:

  1. raise the equilibrium wage and employment
  2. lower the equilibrium wage and employment Correct answer.
  3. raise the wage but always raise employment
  4. leave wage and employment unchanged

Explanation

Lower labor demand shifts the demand curve left; the new intersection has a lower wage and lower employment-key for linking product-market shocks to Arbeitsmärkte.

Question 17Scarcity, markets and consumer decisions

Which pair correctly matches a Magisches Viereck goal with a typical indicator?

  1. price stability - unemployment rate
  2. high employment - CPI inflation rate
  3. external balance - current account / trade balance measures Correct answer.
  4. growth - statutory corporate tax rate alone

Explanation

External balance is monitored via current-account or trade-balance indicators. Inflation uses price indexes; employment uses unemployment/employment rates; growth uses real GDP.

Question 18Scarcity, markets and consumer decisions

Which policy is most clearly an Ordnungspolitik (framework policy) measure rather than process intervention in a single market price?

  1. imposing a temporary price ceiling on one vegetable
  2. competition law that prohibits cartels and abuse of dominance Correct answer.
  3. a one-off voucher only for one firm's customers
  4. central setting of every retail price each week

Explanation

Ordnungspolitik shapes the rules of the game-property rights, competition law, monetary constitution-rather than micromanaging a single market price. That distinction is central to soziale Marktwirtschaft thinking.

Question 19Scarcity, markets and consumer decisions

If autonomous spending rises by EUR 10 bn and the simple spending multiplier is 2, the predicted rise in equilibrium income (closed economy, spare capacity) is:

  1. EUR 5 bn
  2. EUR 10 bn
  3. EUR 20 bn Correct answer.
  4. EUR 40 bn

Explanation

ΔY = multiplier × ΔA = 2 × 10 = EUR 20 bn. Multiplier logic appears in demand-side policy discussions; always state assumptions (spare capacity, simplified model).

Question 20Scarcity, markets and consumer decisions

Crowding-out concerns suggest that higher government borrowing may:

  1. always raise private investment one-for-one
  2. put upward pressure on interest rates and reduce some private investment Correct answer.
  3. eliminate scarcity
  4. make the PPF shift inward immediately by definition

Explanation

If public borrowing raises interest rates, private investment may fall-partial crowding out. The strength depends on monetary conditions and spare capacity.

Question 21Scarcity, markets and consumer decisions

A movement along the demand curve is caused by:

  1. a change in the good's own price Correct answer.
  2. a change in consumer incomes
  3. a change in tastes
  4. a change in the prices of substitutes only, holding own price fixed

Explanation

Own-price changes cause movements along demand. Income, tastes, and related-goods prices shift the demand curve.

Question 22Scarcity, markets and consumer decisions

Cross-price elasticity of demand between butter and margarine is positive. This indicates the goods are:

  1. complements
  2. substitutes Correct answer.
  3. inferior goods
  4. Giffen goods

Explanation

Positive cross-price elasticity means higher price of one raises demand for the other-substitutes. Complements have negative cross-price elasticity.

Question 23Scarcity, markets and consumer decisions

Income elasticity of demand for a product is −0.6. The product is:

  1. a normal luxury
  2. a normal necessity
  3. an inferior good Correct answer.
  4. a public good by definition

Explanation

Negative income elasticity means demand falls as income rises-an inferior good. Luxuries typically have income elasticity > 1; necessities between 0 and 1.

Question 24Scarcity, markets and consumer decisions

Which outcome is most consistent with a binding price ceiling below equilibrium?

  1. persistent surplus and unsold inventories
  2. shortage and non-price rationing (queues, favoritism) Correct answer.
  3. automatic equality of Qd and Qs at the ceiling
  4. higher legal price than the free-market equilibrium

Explanation

A ceiling below equilibrium caps price too low: Qd > Qs, creating shortage and non-price rationing.

Question 25Scarcity, markets and consumer decisions

Graph interpretation: After a successful innovation lowers firms' marginal costs, the supply curve shifts right. Holding demand fixed, equilibrium price _____ and equilibrium quantity _____.

  1. rises; rises
  2. rises; falls
  3. falls; rises Correct answer.
  4. falls; falls

Explanation

Rightward supply shift lowers equilibrium price and raises equilibrium quantity-productivity/cost improvements benefit consumers via lower prices and higher volume.

Question 26Scarcity, markets and consumer decisions

Which is the best example of a positive externality?

  1. noise from a late-night club harming neighbors
  2. basic research that spills over useful knowledge to other firms Correct answer.
  3. theft of private property
  4. a tariff that only redistributes surplus without external effects

Explanation

Positive externalities confer uncompensated benefits on third parties; knowledge spillovers are a standard case and can justify innovation support.

Question 27Scarcity, markets and consumer decisions

Which statement about comparative advantage is correct?

  1. a country should export only goods in which it has absolute advantage in all inputs
  2. mutual gains from trade arise when opportunity costs differ, even if one country is more productive in everything Correct answer.
  3. only large countries can benefit from specialization
  4. comparative advantage ignores opportunity costs

Explanation

Comparative advantage rests on lower opportunity cost. A country can gain from specializing even without absolute advantage in any good-core trade logic linked to global markets units.

Question 28Scarcity, markets and consumer decisions

A Lorenz curve farther from the diagonal indicates:

  1. perfect equality of income
  2. greater inequality of income distribution Correct answer.
  3. a higher inflation rate by definition
  4. a trade surplus

Explanation

The Lorenz curve plots cumulative income share against cumulative population share. Greater bow away from the 45° line means more inequality; the Gini coefficient summarizes that gap.

Question 29Scarcity, markets and consumer decisions

Which policy mix best matches supply-side economics aimed at potential output?

  1. only raising unemployment benefits permanently with no activation
  2. measures that improve incentives, skills, competition, and productive capacity Correct answer.
  3. freezing all prices by decree forever
  4. banning technological change

Explanation

Supply-side policy targets potential output and efficiency-skills, infrastructure, competition, tax/transfer incentive design-not merely short-run demand.

Question 30Scarcity, markets and consumer decisions

If the money wage is sticky downward and labor demand falls, unemployment is more likely because:

  1. the real wage instantly falls enough to clear the market
  2. the wage may remain above the new market-clearing level, creating excess labor supply Correct answer.
  3. labor supply becomes perfectly inelastic automatically
  4. firms must hire more workers by law

Explanation

Downward wage stickiness prevents immediate market clearing after a demand shock, generating classical/Keynesian unemployment mechanisms discussed alongside Arbeitsmärkte.

Question 31Scarcity, markets and consumer decisions

Which statement about GDP as a welfare measure is most accurate?

  1. GDP per capita captures all aspects of well-being including unpaid care and environment perfectly
  2. GDP is a useful production/income indicator but omits many welfare dimensions (leisure, environment, inequality, non-market work) Correct answer.
  3. GDP equals the happiness index by construction
  4. a higher GDP always means lower inequality

Explanation

Critical evaluation of indicators is part of competent economic analysis: GDP is central but incomplete for welfare.

Question 32Scarcity, markets and consumer decisions

An appreciation of the domestic currency, other things equal, tends to:

  1. make domestic exports cheaper for foreign buyers
  2. make domestic exports more expensive for foreign buyers and imports cheaper domestically Correct answer.
  3. have no effect on relative prices of tradables
  4. automatically raise net exports

Explanation

A stronger currency raises the foreign-currency price of exports and lowers the domestic price of imports, typically pressuring net exports downward (ceteris paribus).

Question 33Scarcity, markets and consumer decisions

Which best describes Anforderungsbereich II in EPA Wirtschaft terms for a written task?

  1. pure reproduction of definitions with no transfer
  2. reorganization, transfer, and application of known methods to analyze economic material Correct answer.
  3. only creative design of an entirely new economic system with no data
  4. copying a textbook paragraph without operators

Explanation

EPA Wirtschaft structures AFB I (reproduction), II (reorganization/transfer/application-typical emphasis), and III (problem solving/judgment/transfer to new contexts). Facherlass states Klausur emphasis on AFB II.

Question 34Firms, business and labor

In business administration, the economic principle (Wirtschaftlichkeitsprinzip) in the minimum version means:

  1. achieve a given output with the least possible input Correct answer.
  2. use infinite inputs to maximize waste
  3. ignore costs when quality matters
  4. maximize headcount regardless of output

Explanation

The minimum principle seeks a defined result with minimal resource use; the maximum principle seeks the greatest result from given resources. Both express economic efficiency in BWL.

Question 35Firms, business and labor

Fixed costs are costs that:

  1. vary proportionally with every unit produced in the short run
  2. remain constant in total when output changes within a relevant range Correct answer.
  3. are always zero in manufacturing
  4. equal price times quantity

Explanation

Fixed costs do not change with output in the short run (rent, salaried overhead). Variable costs change with output.

Question 36Firms, business and labor

A firm has fixed costs of EUR 2,000 and variable cost of EUR 15 per unit. At 200 units, total cost is:

  1. EUR 2,000
  2. EUR 3,000
  3. EUR 5,000 Correct answer.
  4. EUR 7,000

Explanation

TC = FC + VC = 2,000 + 15×200 = 2,000 + 3,000 = EUR 5,000.

Question 37Firms, business and labor

Contribution margin per unit equals:

  1. price minus variable cost per unit Correct answer.
  2. price minus fixed cost per unit only
  3. total revenue minus total fixed costs ignoring variable costs
  4. average cost minus marginal cost

Explanation

Deckungsbeitrag per unit = price − variable cost per unit. It contributes to covering fixed costs and profit-standard BWL calculation.

Question 38Firms, business and labor

Price is EUR 50, variable cost EUR 30, fixed costs EUR 10,000. Break-even quantity (units) is:

  1. 200
  2. 334
  3. 500 Correct answer.
  4. 1,000

Explanation

Break-even Q = FC / (P − VC) = 10,000 / (50−30) = 10,000 / 20 = 500 units.

Question 39Firms, business and labor

Equity financing differs from debt financing because equity:

  1. must always be repaid on a fixed schedule like a bank loan
  2. represents ownership claims and typically has no fixed repayment obligation like interest-bearing debt Correct answer.
  3. never involves risk for investors
  4. is illegal for corporations

Explanation

Equity is ownership capital; returns are residual (dividends/capital gains), not contractual interest. Debt creates fixed claims and repayment obligations.

Question 40Firms, business and labor

Make-or-buy decisions should compare:

  1. only the purchase price ignoring quality and transaction costs
  2. relevant internal production costs versus purchasing costs including quality, risk, and dependency Correct answer.
  3. sunk historical costs only
  4. the CEO's favorite supplier brand without cost data

Explanation

Rational make-or-buy uses relevant costs and strategic factors (quality, hold-up risk, core competencies)-BWL decision logic.

Question 41Firms, business and labor

If a firm's contribution margin is positive but total contribution is less than fixed costs, the firm:

  1. earns an accounting profit
  2. covers part of fixed costs but still makes a loss Correct answer.
  3. must have negative variable costs
  4. is at long-run equilibrium profit by definition

Explanation

Positive unit CM means each sale helps; if total CM < FC, the firm still loses money but may continue short run if CM > 0 and FC are sunk.

Question 42Firms, business and labor

Which financing source is typically external debt?

  1. retained earnings
  2. a bank loan Correct answer.
  3. owners' new equity capital injection
  4. depreciation as an internal financing source

Explanation

Bank loans are external borrowed capital. Retained earnings and depreciation-related funds are internal; new shares are external equity.

Question 43Firms, business and labor

Economies of scale mean that as output expands in the long run:

  1. long-run average cost rises continuously
  2. long-run average cost falls over a range of output Correct answer.
  3. fixed costs become variable instantly by definition
  4. demand disappears

Explanation

Economies of scale: LRAC declines as scale increases (specialization, spreading indivisibilities). Diseconomies appear when LRAC rises at very large scale.

Question 44Firms, business and labor

A firm raises price in a market segment with very inelastic demand and lowers price where demand is elastic. This price discrimination logic aims to:

  1. minimize revenue in both segments
  2. raise total revenue by exploiting different elasticities Correct answer.
  3. violate the definition of elasticity
  4. make supply perfectly inelastic

Explanation

Third-degree price discrimination charges higher prices where demand is less elastic. Revenue/profit can rise if markets can be separated-marketing/pricing BWL application.

Question 45Firms, business and labor

Which cost is sunk for a forward-looking decision?

  1. the non-refundable license fee already paid last year Correct answer.
  2. the future wage of a worker not yet hired
  3. the price of materials for next month's planned production still cancellable
  4. expected energy costs for a project not yet started

Explanation

Sunk costs are already incurred and irrecoverable; rational decisions ignore them and focus on incremental future costs and benefits.

Question 46Firms, business and labor

Productivity rises when:

  1. output falls while inputs stay constant
  2. more output is produced per unit of input Correct answer.
  3. inputs rise faster than output
  4. the firm stops measuring performance

Explanation

Productivity = output per input (e.g., labor productivity). Rising productivity supports competitiveness and real wage potential over time.

Question 47Firms, business and labor

In a competitive labor market diagram, the labor demand curve is typically downward-sloping because:

  1. firms want more workers when wages rise, always
  2. diminishing marginal returns make additional labor less valuable as employment rises Correct answer.
  3. workers refuse all jobs at low wages by law
  4. labor supply is the same as labor demand

Explanation

Firms hire until the value of the marginal product equals the wage; diminishing returns yield a downward-sloping labor demand curve.

Question 48Firms, business and labor

An increase in immigration of working-age people, other things equal, is most likely to:

  1. shift labor supply right and put downward pressure on wages in affected segments Correct answer.
  2. shift labor demand left only
  3. eliminate all firms
  4. make labor supply perfectly inelastic

Explanation

More potential workers shift labor supply right; wage pressure depends on demand elasticity and complementarities, but the basic diagram effect is rightward supply.

Question 49Firms, business and labor

Structural unemployment is most clearly illustrated by:

  1. a software engineer taking two weeks to find a new job after quitting
  2. coal miners remaining jobless because regional demand for their skills has permanently declined Correct answer.
  3. factory workers temporarily laid off in a recession who are rehired in the recovery
  4. students on summer break not seeking work

Explanation

Structural unemployment reflects lasting mismatch (skills, regions, sectors). Frictional is brief search; cyclical is demand-driven; non-seekers are out of the labor force.

Question 50Firms, business and labor

Labor force = employed + unemployed. If employed = 40 million, unemployed = 2 million, and adult population = 60 million, the unemployment rate is:

  1. 3.33%
  2. 5.0%
  3. 4.76% Correct answer.
  4. 10.0%

Explanation

Unemployment rate = unemployed / labor force = 2 / (40+2) = 2/42 ≈ 4.76%. Do not divide by total population for the standard rate.
