Cevabı ve açıklamayı göster

Cevap

Local market matches transactions limited to a specific village or immediate neighborhood; National market matches trading of standardized commodities across all geopolitical zones; Open market matches an unrestricted trading environment without price controls; Black market matches illegal trading of restricted goods outside official price ceilings.

The pairings correctly match each market concept to its defining economic scope: local markets serve immediate small areas due to product perishability, national markets distribute goods nationwide across all zones, open markets rely on unrestricted supply and demand, and black markets operate illegally outside official price regulations.

Adım Adım Çözüm

1

Analyze geographical scope classifications.

Local markets involve immediate community trading, whereas national markets span across the entire country.

Geographical classification depends on the area over which buyers and sellers interact.

2

Analyze legal and regulatory status classifications.

Open markets permit free pricing without statutory barriers, while black markets operate illicitly to bypass official price controls.

Legal classification distinguishes legitimate free-market activities from clandestine trading violating government mandates.

Evaluate the market developments below and match each change in economic conditions (Left) to its corresponding geometric effect on the demand curve for the affected commodity (Right).

Soldaki öğeye tıklayın, sonra eşleşen sağdaki öğeye tıklayın

Cevabı ve açıklamayı göster

Cevap

The market developments match their demand curve effects as follows: Petrol price increase shifts CNG bus demand curve outward (competitive substitute); local rice price reduction causes downward movement along its demand curve (increase in quantity demanded); falling household income shifts cassava flour demand curve outward (inferior good response); health warnings shift refined sugar demand curve inward (adverse taste change).

Each market event is correctly paired by distinguishing between own-price effects (movements along the demand curve) and non-price determinants (shifts of the demand curve). The price hike of petrol increases demand for CNG buses as a substitute (rightward shift). The price drop of local rice increases quantity demanded along its current curve (downward movement). Falling incomes boost demand for cassava flour due to its inferior good property (rightward shift). Health advisories weaken preferences for sugar, shifting its demand curve leftward.

Adım Adım Çözüm

1

Analyze the relationship between petrol and CNG commercial buses.

Since petrol and CNG are substitute energy sources in competitive demand, a rise in the price of petrol increases demand for CNG buses, causing an outward (rightward) shift of the demand curve.

Cross-price effects of substitute goods shift the demand curve of the alternative good.

2

Evaluate the impact of a price change on local unpolished rice itself.

A change in the commodity's own price alters quantity demanded, causing a downward movement along the existing demand curve.

Own-price changes never shift the demand curve; they alter the quantity demanded along the curve.

3

Examine the income effect on low-quality cassava flour as an inferior good.

Because cassava flour is an inferior good, lower real income causes consumers to buy more of it, shifting its demand curve outward to the right.

Inferior goods have an inverse relationship between consumer income and demand.

4

Assess the effect of public health warnings on refined sugar consumption.

Negative publicity reduces consumer preference for sugar, decreasing demand at all price levels and shifting the demand curve inward to the left.

Non-price determinants such as tastes and preferences shift the entire demand curve.

In market economics, changes in price and non-price determinants produce distinct geometric shifts or movements on a commodity's demand curve. Match each specific market event involving fresh milk on the left with its exact geometric outcome on the demand curve on the right.

Soldaki öğeye tıklayın, sonra eşleşen sağdaki öğeye tıklayın

Cevabı ve açıklamayı göster

Cevap

The correct pairings match: (1) price reduction of fresh milk to downward movement along the curve; (2) medical report favoring milk to an outward shift driven by tastes; (3) price increase of fruit juice to an outward shift driven by substitute cross-price elasticity; and (4) decline in consumer income to an inward shift of the demand curve.

Each economic factor correctly maps to its geometric representation: own-price changes result in movement along the curve, positive preference changes and rising substitute prices shift the curve rightward, and falling income for normal goods shifts the curve leftward.

Adım Adım Çözüm

1

Distinguish between a change in price of the good itself and non-price determinants.

Recognize that a change in own-price causes movement along the curve, while non-price determinants shift the curve.

The law of demand specifies that price affects quantity demanded (movement), whereas external non-price factors alter overall demand (shift).

2

Analyze the impact of non-price determinants on tastes, substitute prices, and consumer income.

Determine the direction of shifts: positive tastes and higher substitute prices shift demand rightward; lower income for normal goods shifts demand leftward.

Substitutes have a direct cross-price relationship with demand for the target good, while normal goods share a direct relationship with consumer income.

The correct matches pair: (1) Ad valorem tariff with revenue generation based on monetary valuation; (2) Export subsidy with expanded producer surplus and potential international countervailing duties; (3) Voluntary export restraint with quantitative restriction where foreign firms capture quota rents; and (4) Total trade embargo with a complete halt in trade creating severe domestic supply deficits.

Each instrument accurately aligns with its definitive economic mechanism: ad valorem tariffs tax percentage value; export subsidies boost domestic export surplus while risking trade disputes; voluntary export restraints transfer quota rents to foreign firms; and embargoes legally cut off trade completely.

Adım Adım Çözüm

1

Analyze the operational mechanism of an ad valorem tariff.

Identified that 'ad valorem' means 'according to value'. It yields revenue proportional to monetary value.

Tariffs based on valuation directly add a percentage tax to imports, raising revenue for the state treasury.

2

Analyze the impact of export subsidies on domestic producers and foreign trade partners.

Identified that financial assistance to exporters increases domestic producer surplus and lowers export prices abroad.

Subsidies lower costs for domestic exporters, expanding output but potentially distorting international market prices.

3

Examine how Voluntary Export Restraints (VERs) differ from standard import quotas in terms of rent capture.

Identified that VERs allow foreign exporting firms to capture the quota rents due to price increases in the destination market.

Because the exporting country self-administers the limit, foreign firms set higher prices and retain the economic rent.

4

Evaluate the absolute economic constraint imposed by a trade embargo.

Identified that an embargo is a zero-trade mandate causing total cessation of legal imports and acute market shortages.

Cevap

Absolute Advantage pairs with producing using fewer total resource inputs; Comparative Advantage pairs with producing at lower domestic opportunity cost; Opportunity Cost of a Good (Output basis) pairs with the ratio of alternative commodity sacrificed to target commodity produced; Mutually Beneficial Terms of Trade pairs with an exchange rate bounded by the domestic cost ratios of both nations.

Absolute advantage measures production efficiency directly by resource inputs, comparative advantage measures relative efficiency via sacrificed alternative output, opportunity cost in output models reflects foregone output of the alternative good per unit of target good, and beneficial international terms of trade are strictly bounded by the domestic cost ratios of the two trading nations.

Adım Adım Çözüm

1

Identify the definition of Absolute Advantage

Adam Smith defined absolute advantage as the ability of a nation to produce a commodity with absolute higher efficiency (fewer input resources per unit) than another nation.

It measures absolute productivity differences across nations.

2

Identify the definition of Comparative Advantage

David Ricardo demonstrated that trade is mutually beneficial if a country specializes in producing goods at a lower relative opportunity cost.

Comparative advantage relies on relative price/cost ratios rather than absolute efficiency.

3

Determine the output-based formula for Opportunity Cost

Opportunity cost of Good X equals

\frac{\text{Output of Good Y}}{\text{Output of Good X}}

, representing the sacrificed quantity of Good Y per unit of Good X gained.

Output-based measures evaluate trade-offs in terms of foregone output.

Cevap

The correct matches pair: (1) Price change of LPG itself to an upward movement along the existing demand curve; (2) Price increase of substitute fuels to an outward rightward shift driven by substitute price changes; (3) Fall in household disposable income to an inward leftward shift caused by reduced purchasing power; and (4) Expectation of future price increase to an outward rightward shift driven by consumer expectations.

Price changes of the product itself move consumers along the existing curve (contraction or expansion), while non-price determinants (substitute prices, income, and buyer expectations) shift the position of the demand curve.

Adım Adım Çözüm

1

Separate price determinants from non-price determinants.

The price of LPG itself is a price determinant, causing a movement along the curve (change in quantity demanded). Substitute prices, consumer income, and expectations are non-price determinants, causing shifts of the curve (change in demand).

Changes in price alter quantity demanded along an existing curve, whereas changes in non-price factors shift the curve to a new position.

2

Determine the direction of shift for each non-price factor.

Higher substitute prices increase LPG demand (rightward shift). Reduced income decreases normal good demand (leftward shift). Expected future price rises increase current demand (rightward shift).

Each non-price determinant systematically shifts consumer willingness and ability to purchase at given price levels.
