Consider the following statements and choose the correct option: Statement 1: The Production Possibility Frontier (PPF) shows the trade-offs and opportunity costs faced by an economy. Statement 2: The PPF is used to estimate the government’s total revenue and expenditure.

Correct — A. Statement 1 is true. A PPF shows the combinations of two goods an economy can produce when its resources are fully and efficiently used.

Moving along it, more of one good means less of the other. That is the trade-off, and the output given up is the opportunity cost.

Statement 2 is false. Government revenue and expenditure are estimated in the budget, not on a PPF: option (a).

Why the others are wrong

• (b)
  Only Statement 2 is correct — Keeps the false statement and drops the true one. A PPF maps output choices between two goods, while government revenue and spending are set out in the budget.
• (c)
  Both Statement 1 and Statement 2 are correct — Statement 2 breaks 'both'. The PPF's axes are quantities of two goods, so it cannot estimate what the government collects or spends.
• (d)
  Neither Statement 1 nor Statement 2 is correct — Statement 1 is the textbook use of a PPF. Its slope is the opportunity cost of one good in terms of the other, so 'neither' discards a true statement.

The production possibility frontier shows the most an economy can produce of two goods with given resources and technology.

A point on the curve is efficient, a point inside means unused or wasted resources, and a point outside is unattainable for now.

Its slope is the marginal opportunity cost, or marginal rate of transformation. It is usually drawn concave to the origin because that cost rises as production shifts.

Key facts

• A PPF shows the combinations of two goods that can be produced with given resources and technology when resources are fully used.
• The slope of the PPF is the marginal opportunity cost, also called the marginal rate of transformation.
• Points inside the PPF show under-used resources, and points outside it are unattainable with current resources.
• Government revenue and expenditure estimates are presented in the Union Budget, the Annual Financial Statement.

Common traps

• Reading a point inside the curve as impossible: inside is attainable but wasteful, and outside is the unattainable region.
• Treating the PPF as a fiscal tool because it involves choices: its axes are quantities of goods.
