Two Approaches to Producer's Equilibrium

There exist two approaches to explain the producer's equilibriumviz.

1. TR-TC Approach
2. MR-MC Approach
• 1)MC = MR approach conditions
• (i) MC = MR
• (ii) MC is greater than MR after the MC = MR output
• level
• (i) MC = MR
• When one more unit of output is produced, MR is the gain and MC is the
• cost to the producer.Clearly, so long as benefit is greater than the cost, or
• MR is greater than MC, it is profitable to produce more. Therefore, so long as
• MR is greater than MC, the maximum profit level, or the equilibrium level is
• not reached. The equilibrium is not achieved because it is possible to add to
• profits by producing more.
• The producer is also not in equilibrium when MR is less than MC because
• benefit is less than the cost. By producing less the producer can add to his
• profits.
• When MC is equal to MR, the benefit is equal to cost, the producer is in
• equilibrium subject to that MC becomes greater than MR beyond this level of
• output.
• When MC equals MR(subject to the supporting condition) the producers
• profit would be less if he produces output more than or less than the MC =
• MR output as explained above.
• Therefore, for equilibrium to reach it is a necessary condition (but not
• sufficient) that MC equals MR.
• (2) MC is greater than MR after MC = MR output level
• MC = MR is a necessary condition but not sufficient enough to ensure
• equilibrium.
• It is because the producer may face more than one MC =MR outputs.
• But out of these only that output beyond which MC becomes greater
• than MR is the equilibrium output. It is because if MC is greater than
• MR, producing beyond MC = MR output will reduce profits. And when it
• is no longer possible to add to profits the maximum profit level is
• reached.
• On the other hand, if MC is less than MR beyond the MC = MR output, it is
• possible to add to profits by producing more. Therefore this MC = MR level is
• not the equilibrium level.
• For a producer to be in equilibrium it is necessary that MC equals MR as well
• MC becomes greater than MR if more output is produced.
• 3. TR-TC Approach

According to this approach, a firm (or a producer) maximises its profit, where the difference between TR and TC is the maximum i.e.

Profit () =TRTC

where, represents Profit

TRrepresents Total Revenue

TCrepresents Total Cost

4. From the graph and the schedule we can analyse that TR is equal to TC at two points K and M. These points are called break-even points, where TR = TC, i.e. at these points, profits are zero. The maximum vertical distance EF between TR and TC happens at output level ofOQx. Therefore, it is the profit maximisation or the producer's equilibrium point
