If a more efficient technology was discovered by a firm, there would be Multiple Choice a downward shift in the AFC curve. an upward shift in the AFC curve. an upward shift in the AVC curve. a downward shift in the MC curve.

a) a downward shift in the AFC curve

Explanation:

AFC = Average Fixed Cost, AVC = Average Variable Cost, MC = Marginal Cost

Average Fixed Cost is defined as the fixed cost of production divided by the quantity produced. Mathematically given as:

Average Fixed Cost = Fixed Cost : Quantity

AVC = FC : Q

Average Variable Cost is defined as the variable cost of production divided by the quantity produced. Mathematically given as:

AFC = VC : Q

Marginal Cost is defined as the cost incurred for an additional unit to be produced. Mathematically given as:

MC = ΔC : ΔQ

The firm discovered a more efficient technology implies that the cost of production is reduced. The result of this is that the fixed cost (FC) is reduced and consequently, the AFC is reduced as well. Hence, the AFC curve shifts downward. We therefore see that a reduction in fixed costs (due to the discovery of a more efficient technology) results in the AFC curve shifting downwards

Hence, Option A (a downward shift in the AFC curve) is the correct answer
