This Production Possibilities Graph quiz helps you practice PPF curves, trade-offs, and opportunity cost so you can spot efficient, inefficient, and unattainable points. Work through quick items and see where you need review before a test. For extra practice, try this PPF practice set or more opportunity cost problems .

What does a production possibilities frontier illustrate?
The trade?offs and opportunity costs between two goods
Market equilibrium between supply and demand
The supply curve for a single good
Consumer preferences across different products
A production possibilities frontier (PPF) illustrates the maximum attainable combinations of two goods given fixed resources and technology. It highlights the trade?offs and opportunity costs inherent in shifting resources from one good to another. Points on the PPF are productively efficient, while points inside it represent inefficiency.
A point inside the production possibilities frontier indicates:
Productive efficiency
That resources are not being fully utilized
Maximum production capacity
An unattainable output combination
A point inside the PPF means the economy is operating below its potential, indicating underutilized or idle resources. Occurrences such as unemployment or inefficiency can cause such slack. To reach the frontier, the economy must better allocate resources or improve productivity.
If opportunity costs remain constant as production shifts between two goods, the PPF will be what shape?
A straight line
A vertical line
Bowed?outward curve
Bowed?inward curve
When opportunity costs are constant, each additional unit of one good always costs the same amount of the other good, creating a linear PPF. No increasing or decreasing trade?off is present, so the frontier appears as a straight line. This contrasts with most real?world scenarios where costs vary and the PPF is bowed.
On a production possibilities graph, what does the slope of the frontier represent?
The marginal rate of transformation between two goods
The production function
Consumer willingness to pay
The total output level of both goods
The slope of the PPF measures the marginal rate of transformation (MRT), which is the rate at which one good must be given up to produce an additional unit of another good. It reflects opportunity costs at different points on the curve. A steeper slope indicates a higher cost of producing the good on the x?axis.
Which of the following would cause an outward shift of the PPF?
An increase in unemployment
Decrease in consumer demand
A natural disaster destroying capital
Improvement in production technology
An improvement in production technology allows more output to be produced with the same resources, shifting the PPF outward. This expansion reflects higher productive capacity. Decreases in demand or resource destruction would not shift the PPF outward.
When opportunity costs increase as more of a good is produced, the PPF will appear:
Vertical
Linear
Bowed-outward from the origin
Concave inward
Increasing opportunity costs arise because resources are not equally efficient in producing both goods, causing the PPF to bow outward. As production of one good expands, more and more of the other good must be sacrificed. This convex shape reflects escalating trade?offs.
Suppose an economy can operate at combinations B and C on its PPF: B = (60 units of tea, 20 units of coffee) and C = (20 units of tea, 40 units of coffee). What is the opportunity cost of producing one additional unit of coffee when moving from B to C?
1 unit of tea
2 units of tea
4 units of tea
0.5 units of tea
Moving from B to C, tea production falls from 60 to 20 (a loss of 40 units) while coffee rises from 20 to 40 (a gain of 20 units). The opportunity cost of each additional coffee unit is the tea given up: 40 ÷ 20 = 2 units of tea per coffee. This calculation illustrates how opportunity cost varies along the PPF.
If an economy discovers a new resource that only increases production of capital goods, how will the PPF change?
It will become a straight line
It will pivot inward along consumption goods axis
It will shift outward only along the axis for capital goods
It will shift outward equally for both goods
A resource that specifically enhances capital goods production extends the maximum quantity of that good, causing the PPF to pivot outward along the capital axis. The production capacity for consumer goods remains unchanged. This asymmetrical shift reflects sector?specific growth.
Country A gives up 3 computers to produce 1 car, while Country B gives up 2 computers to produce 1 car. Which country has the comparative advantage in car production?
Both have the same comparative advantage
Country A
Neither country
Country B
Comparative advantage is determined by who has the lower opportunity cost. Country B sacrifices only 2 computers per car, whereas Country A sacrifices 3. Therefore, Country B has the comparative advantage in producing cars. Specializing based on this leads to gains from trade.
After two countries specialize according to comparative advantage and engage in trade, the limit to possible consumption bundles lies on which curve relative to its original PPF?
Aggregate demand curve
Consumption possibility frontier
Community indifference curve
Utility transformation curve
When countries specialize and trade, they can consume beyond their own production capabilities. The curve that represents these new consumption limits is called the consumption possibility frontier (CPF). It lies outside the original PPF, illustrating gains from trade.

Cheat Sheet

  1. PPF Shape and the Law of Increasing Opportunity Cost -

    The production possibilities frontier is typically concave because resources are not perfectly adaptable across all goods, as described in Mankiw's Principles of Economics. According to this law, producing each additional unit of one good requires larger and larger sacrifices of the other, which you can easily spot when plotting a bowed”out curve. A mnemonic trick: "The more you make, the more you forsake."

  2. Calculating Opportunity Cost with PPF Slopes -

    Opportunity cost is the slope of the PPF, calculated as ΔGood Y divided by ΔGood X when moving between production points, per Investopedia's definition. For example, if shifting from point A to B sacrifices 5 units of food to gain 10 units of clothing, the opportunity cost of one clothing unit equals 0.5 food units (5/10). Practice this formula to ace your production possibility curve quiz!

  3. Plotting a PPF Using a Production Possibilities Graph Maker -

    When using a production possibilities graph maker, start by labeling your axes for two goods and inputting resource constraints, following guidelines from Khan Academy. Then plot feasible combinations (like points A, B, C) and connect them with a smooth curve to visualize trade”offs. This hands”on approach helps solidify your understanding before tackling PPF curve questions.

  4. Shifts in the Production Possibilities Frontier -

    Factors such as technological breakthroughs or changes in resource availability cause the PPF to shift outward or inward, as noted by the U.S. Bureau of Economic Analysis. For instance, a new automation technology in car manufacturing shifts the frontier outward, indicating higher potential output. Recognizing these shifts is key to mastering the production possibilities frontier quiz.

  5. Comparative Advantage and Specialization on the PPF -

    Comparative advantage emerges when one producer has a lower opportunity cost for a particular good, a principle highlighted in the Journal of Economic Perspectives. By comparing slopes on each producer's PPF, you can determine who should specialize in which good to maximize total output. Remember the phrase "lowest loss, highest gain" to recall the essence of specialization.
