Economic Efficiency

The fundamental economic problem is a scarcity of resources.

Definition of Efficiency

Efficiency is concerned with the optimal production and distribution or these scarce resources.

There are different types of efficiency

1. Productive efficiency.

This occurs when the maximum number of goods and services are produced with a given amount of inputs. This will occur on the production possibility frontier. On the curve it is impossible to produce more goods without producing less services.Productive efficiency will also occur at the lowest point on the firms average costs curve

See: Productive Efficiency

2. Allocative efficiency

This occurs when goods and services are distributed according to consumer preferences. An economy could be productively efficient but produce goods people don’t need this would be allocative inefficient.

A2: Allocative efficiency occurs when the price of the good = the MC of production

See: Allocative Efficiency

3. X inefficiency:

This occurs when firms do not have incentives to cut costs, for example a monopoly which makes supernormal profits may have little incentive to get rid of surplus labour.
Therefore a firms average cost may be higher than necessary.

See: X Inefficiency

4. Efficiency of scale

This occurs when the firms produces on the lowest point of its Long run average cost and therefore benefits fully from economies of scale

5. Dynamic efficiency This refers to efficiency over time for example a Ford factory in 1920 would be very efficient for the time period, but by comparison would now be inefficient.. Dynamic efficiency involves the introduction of new technology and working practises to reduce costs over time.

6. Social efficiency

This occurs when externalities are taken into consideration and occurs at an output where the social cost of production (SMC) = the social benefit (SMB)

See: Social Efficiency

7. Technical Efficiency

Optimum combination of factor inputs to produce a good: related to productive efficiency.

See: Technical Efficiency

8. Pareto Efficiency

A situation where resources are distributed in the most efficient way. It is defined as a situation where it is not possible to make one party better off without making another party worse off.

See: Pareto Efficiency

9. Distributive Efficiency

Concerned with allocating goods and services according to who needs them most. Therefore, requires an equitable distribution.
