Allocative efficiency is achieved when firms produce at the lowest point of their average total cost curve, while productive efficiency is achieved when they produce at the minimum of their marginal cost curve
Allocative efficiency is only relevant in monopoly markets, while productive efficiency is relevant in perfectly competitive markets
