Isoquant: Defining Combinations of Factors for Output

An Isoquant in economics is a curve that graphically represents all possible combinations of two input factors (such as labor and capital) that yield the same level of output. The question specifically asks for the term describing this relationship.

Understanding the Terminology

  • Isoquant: This term directly matches the definition provided in the question. It shows different input bundles that produce an identical quantity of output. For example, a firm could produce 100 units using many workers and little machinery, or fewer workers and more machinery; an isoquant maps these combinations.
  • Duopoly: This refers to a market structure dominated by only two sellers, not a production possibility curve.
  • Long run: This is a time period in production theory where all factors of production are variable, not a specific type of curve.
  • Elasticity: This measures the responsiveness of one economic variable (like quantity demanded) to a change in another (like price), unrelated to production factor combinations.

Therefore, the correct term for a curve showing all combinations of two factors that produce a given output is an Isoquant.
