The table below shows the production possibilities for an economy producing Good X and Good Y:

CombinationGood X (units)Good Y (units)
A050
B1045
C2035
D3020
E400

What is the opportunity cost of increasing the production of Good X from 20 units to 30 units, expressed in units of Good Y?

Cevabı ve açıklamayı göster

Cevap: 15

Cevap

The opportunity cost of increasing the production of Good X from 20 units to 30 units is 15 units of Good Y.
Moving from Combination C to Combination D on the Production Possibility Curve increases the output of Good X from 20 units to 30 units. To achieve this, the economy must reduce its output of Good Y from 35 units to 20 units. The opportunity cost is the amount of Good Y given up, which equals 3520=1535 - 20 = 15 units of Good Y.

Adım Adım Çözüm

1
Find the initial production level of Good Y at Combination C (Good X = 20 units).
35 units of Good Y
This establishes the baseline production of Good Y prior to increasing Good X.
2
Find the new production level of Good Y at Combination D (Good X = 30 units).
20 units of Good Y
This establishes the remaining production of Good Y after resources are reallocated to produce 10 additional units of Good X.
3
Calculate the difference in Good Y output between Combination C and Combination D.
3520=1535 - 20 = 15 units of Good Y
Opportunity cost is defined as the foregone quantity of Good Y required to obtain the additional units of Good X.

A student receives a cash gift of ₦5,000 and must choose between buying a prescribed Economics textbook and purchasing a new pair of shoes, both priced at ₦5,000. If the student decides to buy the textbook, what is the opportunity cost of this decision?

Cevabı ve açıklamayı göster

Cevap: The pair of shoes foregone

Cevap

The pair of shoes foregone
Opportunity cost represents the real cost of a choice, expressed in terms of the next best alternative foregone. Because purchasing the textbook means giving up the pair of shoes, the shoes represent the opportunity cost.

Adım Adım Çözüm

1
Identify the scarce resource and the competing alternatives.
The student has a limited budget of ₦5,000 and two mutually exclusive wants: a textbook and shoes.
Scarcity of resources forces consumers to make a choice among competing wants.
2
Apply the definition of opportunity cost to the choice made.
By selecting the textbook, the student sacrifices the opportunity to own the pair of shoes.
Opportunity cost (real cost) is defined as the next best alternative foregone when a choice is executed.

In his 1932 essay, Lord Lionel Robbins provided a widely accepted definition of economics. Which of the following best describes economics according to his definition?

Cevabı ve açıklamayı göster

Cevap: The study of human behaviour as a relationship between ends and scarce means which have alternative uses

Cevap

According to Lionel Robbins, economics is the study of human behaviour as a relationship between ends and scarce means which have alternative uses.
Lionel Robbins defined economics as the science which studies human behaviour as a relationship between ends and scarce means which have alternative uses. This definition focuses on the core economic problem: unlimited human wants existing alongside limited resources.

Adım Adım Çözüm

1
Identify the fundamental components of Lionel Robbins' definition of economics.
Robbins defined economics around four main elements: human wants (ends) are unlimited, time and resources (means) are limited/scarce, and these scarce means can be put to alternative uses.
This analytical definition shifted the core focus of economics to scarcity and resource allocation.
2
Compare the key components with the provided options.
The choice describing human behaviour as a relationship between ends and scarce means with alternative uses matches Robbins' classic definition word for word.
The remaining options describe monetary costs, Adam Smith's wealth definition, or specific growth dynamics.

Cevabı ve açıklamayı göster

Cevap

Scale of Preference matches with a list of unsatisfied wants arranged in order of relative importance. Priority Ranking matches with placing the most pressing needs at the top and less pressing ones at the bottom. Choice matches with the act of selecting the most urgent want from a list of desires. Opportunity Cost matches with the real sacrifice or alternative forgone when a preferred want is satisfied.
A scale of preference is a list of unsatisfied wants ordered by importance. Ordering wants by urgency represents priority ranking. Selecting an item from the scale is making a choice, and the alternative given up in the process constitutes the opportunity cost.

Adım Adım Çözüm

1
Identify the primary definition of a Scale of Preference.
Recognize that a scale of preference is a structured list of unsatisfied wants sorted by importance.
This establishes the fundamental framework of consumer choice under scarcity.
2
Differentiate between priority ranking, choice, and opportunity cost.
Priority ranking is the ordering mechanism; choice is the selection action; opportunity cost is the resulting sacrificed alternative.
Distinguishing these core concepts prevents confusing monetary expense with economic opportunity cost.

A high school student in Ibadan receives an allowance of 10,000\text{₦}10,000 and must choose between purchasing a prescribed Economics textbook and attending a weekend tutorial class. She decides to buy the textbook. Within the scope of basic economic concepts, what does the unchosen tutorial class represent, and why?

Cevabı ve açıklamayı göster

Cevap: The opportunity cost, because it is the next best alternative foregone due to resource scarcity.

Cevap

The unchosen tutorial class represents the opportunity cost, as it is the real alternative foregone when limited financial resources are allocated to satisfy a preferred want.
The correct answer highlights that economics studies human behavior as a relationship between ends and scarce means with alternative uses. When a student chooses a textbook over a tutorial class, the sacrificed tutorial class represents the real alternative foregone, which is defined as opportunity cost.

Adım Adım Çözüm

1
Identify the constrained resource and competing wants.
The student has a limited allowance of 10,000\text{₦}10,000 (scarcity) and two competing desires: buying a textbook or attending a tutorial.
Economic analysis begins with scarcity requiring choice.
2
Analyze the decision made and the alternative given up.
The student chooses the textbook, leaving the tutorial class unchosen.
Satisfaction of one want implies sacrificing another.
3
Relate the foregone option to economic definitions.
The sacrificed tutorial class is the opportunity cost (real cost) of acquiring the textbook.
Robbins and standard economic definitions state that economic behavior arises because resources are scarce and have alternative uses.

Cevap: The opportunity cost, which is represented by the foregone benefits and potential income of the graphic design business.

Cevap

The opportunity cost, which is represented by the foregone benefits and potential income of the graphic design business.
The decision involves microeconomic analysis where resources are scarce. The true economic cost of choosing the digital skill bootcamp is the opportunity cost—the foregone value, satisfaction, and income that could have been derived from buying the laptop and running the graphic design business.

Adım Adım Çözüm

1
Identify the economic nature of the scenario
An individual decision-maker allocating scarce financial resources (₦50,000) between two mutually exclusive options.
Economic analysis of individual household or individual consumer choices falls within the domain of microeconomics.
2
Distinguish between financial (money) cost and real (opportunity) cost
The financial cost is ₦50,000, but the economic cost is the sacrificed alternative (the laptop and graphic design business).
Economics defines cost primarily in terms of foregone opportunities rather than monetary expenditure.
3
Select the option that correctly captures the true economic cost
The foregone benefits of the graphic design business constitute the opportunity cost of attending the bootcamp.
Scarcity of resources necessitates choice, and every choice incurs an opportunity cost.

Cevabı ve açıklamayı göster

Cevap

The correct pairings are: 'Selecting Textbooks and School Shoes for purchase' matches 'Satisfaction of effective demand within the income constraint'; 'Forgoing the Scientific Calculator' matches 'Opportunity cost (real cost) of the selected items'; 'Ranking Textbooks higher than School Shoes' matches 'Evaluation of relative marginal utility'; and 'Inability to purchase all items on the list' matches 'Direct consequence of scarcity of economic resources'.
A scale of preference is a list of unsatisfied wants arranged in order of relative importance. It enables a rational consumer to maximize utility under income constraints. Here, purchasing Textbooks and Shoes fulfills effective demand within the N12,000\text{N}12,000 limit. The highest-ranked unfulfilled want, the Scientific Calculator, is the opportunity cost. The ordering of items reflects relative marginal utility, and the overall shortfall of funds illustrates scarcity.

Adım Adım Çözüm

1
Calculate total expenditure from available income
Income = N12,000\text{N}12,000. Purchasing Textbooks (N7,000\text{N}7,000) and School Shoes (N5,000\text{N}5,000) exhausts the budget total (N12,000\text{N}12,000).
Determines which wants become effective demand.
2
Identify the opportunity cost of the choice
The next highest priority item that remains unfulfilled is the Scientific Calculator (N4,000\text{N}4,000).
Opportunity cost is defined as the next best alternative forgone, not the total monetary outlay or all unfulfilled wants combined.
3
Analyze the priority order on the scale of preference
Textbooks are ranked above School Shoes because they yield higher relative marginal utility to the student.
A scale of preference ranks wants according to their urgency and utility to the individual.

Cevap: 33 tons of Rice, representing a trade-off via reallocation of existing resources along the curve

Cevap

The opportunity cost is 33 tons of Rice per additional ton of Palm Oil, representing a trade-off via reallocation of existing resources along the curve.
The correct answer accurately calculates the marginal opportunity cost (3030 tons of Rice sacrificed divided by 1010 tons of Palm Oil gained = 33 tons of Rice per ton of Palm Oil) and correctly identifies that choosing a different production combination using a fixed resource base constitutes movement along the Production Possibility Curve.

Cevap

'What to produce' pairs with consumer demand and market price determination; 'How to produce' pairs with technical efficiency and least-cost factor combination; 'For whom to produce' pairs with income distribution and purchasing power; 'Efficient resource allocation' pairs with operating on the Production Possibility Frontier.
Each fundamental economic problem corresponds to a specific decision process in society: determining production priorities based on consumer demand ('What to produce'), selecting optimal production methods based on factor costs ('How to produce'), distributing total output based on purchasing power ('For whom to produce'), and achieving maximum potential output along the Production Possibility Frontier ('Efficient resource allocation').

Adım Adım Çözüm

1
Identify the core focus of 'What to produce'.
Recognize that deciding which goods and services to produce relies on consumer preferences, market demand signals, and commodity prices.
Limited resources must be directed toward satisfying society's most pressing consumer wants.
2
Analyze the problem of 'How to produce'.
Link this problem to production techniques, input substitution, and minimizing costs.
Producers choose between capital-intensive or labor-intensive methods based on relative factor costs to maximize efficiency.
3
Evaluate 'For whom to produce'.
Connect this to income distribution, effective purchasing power, and factor returns.
The output of an economy is distributed according to who holds purchasing power through wages, rent, interest, and profits.
4
Determine the condition for 'Efficient resource allocation'.
Associate maximum efficiency with full utilization of resources along the Production Possibility Frontier.
Efficiency requires that society cannot produce more of one good without sacrificing another.

A commercial farm in Kaduna operates with fixed total resources of 1010 hectares of arable land and 120120 worker-hours of labor per day. Producing 11 ton of maize requires 11 hectare of land and 1212 worker-hours of labor. Producing 11 ton of yams requires 0.50.5 hectares of land and 2020 worker-hours of labor. Initially, the farm devotes all its resources to maximize maize production, harvesting 1010 tons of maize per day. If the farm owner decides to reallocate resources to produce 33 tons of yams per day, what is the opportunity cost of this decision expressed in tons of maize foregone?

Cevabı ve açıklamayı göster

Cevap: 5

Cevap

The opportunity cost of producing 3 tons of yams is 5 tons of maize.
Producing 3 tons of yams absorbs 60 worker-hours out of the total 120 worker-hours available. The remaining 60 worker-hours can only produce 5 tons of maize. Since initial maize production was 10 tons, the farm gives up 5 tons of maize (10 - 5 = 5 tons).

Adım Adım Çözüm

1
Calculate resources consumed by the production of 3 tons of yams.
Land consumed = 3×0.5=1.53 \times 0.5 = 1.5 hectares. Labor consumed = 3×20=603 \times 20 = 60 worker-hours.
Opportunity cost depends on the amount of productive inputs diverted away from maize production.
2
Determine the remaining inputs available for maize production.
Remaining land = 101.5=8.510 - 1.5 = 8.5 hectares. Remaining labor = 12060=60120 - 60 = 60 worker-hours.
Maize can only be produced using the unallocated land and labor inputs.
3
Identify the binding constraint for maize output.
Labor restricts maize output to 6012=5\frac{60}{12} = 5 tons (since land would permit 8.58.5 tons). Thus, maximum feasible maize output is 55 tons.
Production is restricted by the scarcest resource (labor).
4
Subtract the new maximum maize output from the initial maize output to find the opportunity cost.
10 tons5 tons=5 tons of maize foregone10 \text{ tons} - 5 \text{ tons} = 5 \text{ tons of maize foregone}.
Opportunity cost is defined as the quantity of the alternative good given up.

Remaining angle = 360210=150360^\circ - 210^\circ = 150^\circ.
A full pie chart represents 360360^\circ.
3
Calculate the specific angle allocated to Health using the ratio 3:23:2.
Health angle = 33+2×150=35×150=90\frac{3}{3 + 2} \times 150^\circ = \frac{3}{5} \times 150^\circ = 90^\circ.
Health gets 3 parts out of a total of 5 ratio parts.
4
Convert the Health sector angle to monetary value.
Health expenditure = 90360×720 million=180 million\frac{90^\circ}{360^\circ} \times ₦720\text{ million} = ₦180\text{ million}.
The monetary value is proportional to the ratio of the sector angle to 360360^\circ multiplied by the total budget.

Cevap: The 80,000₦80,000 income foregone from her tailoring shop

Cevap

The 80,000₦80,000 income foregone from her tailoring shop
Opportunity cost is defined as the alternative sacrificed when an economic decision is made. By choosing to attend the workshop, Kemi foregoes the 80,000₦80,000 she would have earned from operating her tailoring shop for that month.

Adım Adım Çözüm

1
Identify the economic choice made and the alternative sacrificed
Kemi chose to attend the training program instead of operating her tailoring shop for the month.
Opportunity cost is defined as the real cost or next best alternative foregone when a choice is made.
2
Distinguish opportunity cost from money cost
Money cost is the actual financial payment (50,000+20,000=70,000₦50,000 + ₦20,000 = ₦70,000), while opportunity cost is the yield of the sacrificed alternative (80,000₦80,000 shop income).
Economic analysis separates real sacrifice (income foregone) from explicit monetary outlays.
