In case the producer's equilibrium shifts to a higher isoquant due to decrease in price of an input, the curve combining the successive equilibrium positions is known as :
Price Factor Curve
Price factor curve — option 2.
What is changing, and that decides everything. The producer’s equilibrium is the point where an isoquant is tangent to an isocost line — the least-cost combination of inputs for that output. When something shifts, the tangency moves, and the curve joining the successive tangencies is named after what caused the shift :
| What changes | What stays constant | Curve joining the new equilibria |
|---|---|---|
| The price of one input | Outlay and the other input’s price | Price factor curve — the isocost line pivots about one axis |
| Total outlay (the budget) | Both input prices | Expansion path — the isocost line shifts outward parallel to itself |
Why this question is a price factor curve. The price of an input falls, so the firm can buy more of that input with the same outlay. The isocost line pivots outward on that input’s axis while its intercept on the other axis is unchanged — it does not shift bodily. Each pivot gives a new tangency on a higher isoquant, and the locus of those tangencies is the price factor curve. It is the producer’s analogue of the consumer’s price consumption curve.
Why the expansion path is the sharpest distractor. It is a real and closely related concept, but it is generated by changing the scale of outlay with relative input prices held constant. Because the price ratio does not change, the isocost lines are all parallel, and the expansion path shows how the firm grows at a fixed input mix. Here the price ratio is precisely what changes, so it cannot be the expansion path.
The other two. The production possibility curve shows the combinations of two outputs obtainable from given resources — a different diagram entirely, in output space rather than input space. “Product line” is a marketing term for a group of related products, and has nothing to do with production theory.
The economics behind the shift. A fall in one input’s price produces two effects, exactly parallel to consumer theory: a substitution effect, as the firm switches toward the now cheaper input, and an output or scale effect, as the same outlay now buys more of everything — which is why equilibrium lands on a higher isoquant.
Hence, the answer is Price Factor Curve.
