Output (Units) | Total Revenue (Rs.) | Marginal Revenue (Rs.) | Total Cost (Rs.) | Marginal Cost (Rs.) |
1 2 3 4 5 | 8 16 24 32 40 | 8 8 8 8 8 | 10 18 23 31 41 | 10 8 5 8 10 |
In the above table,
MR=MC in two situations: (i) when
2 units of output are produced, and (ii) when
4 units of output are produced. However, in situation
1, when output is
2 units,
MC is falling, whereas in situation
2, when output is
4 units,
MC is rising. A producer strikes equilibrium when two conditions are satisfied:
(i)
MR=MC, (ii)
MC is rising.
This means that in the above scenario, equilibrium will be struck when
4 units of output are produced and not when
2 units of output are produced.
When
4 units of output are produced,
TR=Rs.32 and
TC=Rs.31Profit=TR−TCProfit=Rs.32−Rs.31=Rs.1The producer is earning supernormal profit of
Rs.1 at the point of equilibrium.
