An economy achieves "productive efficiency" when :

Question

Accepted Answer

The correct option is 3:
Productive efficiency occurs when an economy or a firm is operating at the lowest possible cost for a given level of output, meaning that no resources are being wasted. In macroeconomic terms, this is achieved when production takes place on the Production Possibilities Curve (PPC), indicating that resources are allocated optimally and maximized utility is achieved from the available factors of production. If resources were wasted or costs were higher than necessary, the economy would be inefficient. Therefore, producing goods using the minimum inputs necessary—at the least cost and with no resource wastage—is the defining feature of productive efficiency.

The incorrect option is 1:
While employing the best resources is important, it does not, by itself, guarantee productive efficiency. Productive efficiency requires using any given set of resources—whether the "best" or not—in the most cost-effective way possible, meaning minimum waste and minimum cost.

The incorrect option is 2:
The goal of productive efficiency is not simply to produce the absolute "greatest total number of goods" but rather to produce any specific output combination at the lowest cost. Maximizing the total number of goods might be possible but could be highly inefficient if the cost per unit is unnecessarily high.

The incorrect option is 4:
This option describes allocative efficiency, not productive efficiency. Allocative efficiency is achieved when resources are used to produce the particular mix of goods and services that society most desires (i.e., where Marginal Benefit equals Marginal Cost). Productive efficiency focuses purely on cost minimization and resource utilization within the production process, irrespective of whether the goods produced are the most "highly valued."
