The midpoint of the curve
undefined
What do points strictly inside the PPF indicate?
Productive inefficiency or unemployment - Correct: Resources are underutilized

undefined
What do points outside the current PPF indicate?
Inefficient outcomes
Currently unattainable without growth, trade, or tech change - Correct: They exceed present resource/tech limits

undefined
Moving along a PPF from one point to another illustrates which core concept?
Producer surplus
Opportunity cost - Correct: Gaining more of one good requires giving up some of the other
Diminishing marginal utility
Price elasticity
undefined
A straight-line PPF implies what about opportunity costs?
They are constant - Correct: Linear frontier means trade-off rate is the same along the curve
They are increasing
They are zero
They are decreasing
undefined
Why is a typical PPF bowed out (concave to the origin)?
Because resources are homogeneous
Because of increasing opportunity costs due to resource specialization - Correct: Resources are better suited to some goods than others
Because preferences are convex
Because of decreasing returns to scale
undefined
At a given point, the (absolute value of the) slope of the PPF equals:
The marginal rate of substitution (MRS)
The price ratio
The marginal rate of transformation (MRT) - Correct: Slope gives the opportunity cost of one good in terms of the other
The income effect
undefined
If technology improves only in producing the good on the horizontal axis, the PPF will:
Shift outward in a parallel fashion
Pivot outward around the vertical intercept - Correct: Only the horizontal-axis maximum expands
Pivot inward around the horizontal intercept
Remain unchanged
undefined
Long-run economic growth from capital accumulation is shown as:
No change in the PPF
An inward pivot of the PPF
A movement along a fixed PPF
An outward shift of the PPF over time - Correct: More resources raise maximum output
undefined
Choosing more capital goods today typically implies what for the future PPF?
It shifts outward faster - Correct: Capital goods raise future productive capacity
It becomes linear
It shifts inward
It remains the same
undefined
Specialization and trade can allow a country to consume:
Exactly on its PPF
Inside its PPF
Beyond its domestic PPF - Correct: Trade can expand consumption possibilities
Only at the intercepts of its PPF
undefined
Given a linear PPF with intercepts at 0Y when X=10 and 0X when Y=20, what is the opportunity cost of 1 unit of X?
20 Y
10 Y
2 Y - Correct: Moving 10 X costs 20 Y, so 1 X costs 2 Y
0.5 Y - Correct: Slope magnitude = 20/10 = 2 Y per 1 X? Wait, X on horizontal so giving up 2Y per 1X; but intercepts show X max 10, Y max 20; OC of 1 X is 2 Y
undefined
Consider PPF combinations: A(0,100), B(20,80), C(40,55), D(60,25) where numbers are (X,Y). The opportunity cost of moving from B to C is:
25 Y - Correct: Gain 20 X, lose 25 Y, so OC of 20 X is 25 Y
-25 Y
1.25 X
20 X
undefined
A convex (bowed-in) PPF would imply:
No scarcity
Decreasing opportunity cost - Correct: The trade-off gets easier as you specialize, an unusual case
Constant opportunity cost
Increasing opportunity cost
undefined
A piecewise-linear (kinked) PPF implies that:
The PPF is inefficient
Opportunity cost jumps at the kink - Correct: Different resource sets become binding
Opportunity cost is the same everywhere
There is no trade-off
undefined
If the endowment of a resource specific to the vertical-axis good increases, the PPF will:
Pivot outward around the horizontal intercept - Correct: The vertical-axis maximum expands, rotating about the horizontal intercept
Pivot outward around the vertical intercept
Shift inward
Not change
undefined
The socially optimal production point on the PPF in a simple model with well-behaved preferences is where:
MRT < MRS
An indifference curve is tangent to the PPF (MRT = MRS) - Correct: Marginal trade-offs match preferences
Utility is minimized
MRT > MRS
undefined
If two sectors use completely specific resources (no cross-usage), the PPF will most likely:
Be a smooth bowed-out curve
Be L-shaped with a sharp kink - Correct: Trade-off is zero until specific resources are fully used, then becomes steep
Be a straight line
Be a circle
undefined
For trade to let two countries both consume beyond their own PPFs, the terms of trade must:
Be below both countries' opportunity costs
Equal each country's opportunity cost of the exported good
Lie between the countries' opportunity costs - Correct: Ensures mutual gains
Be set arbitrarily high
undefined

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.
