There are two approaches to determine producer's equilibrium:
(i) Marginal Revenue and Marginal Cost approach
(ii) Total Revenue and Total Cost approach
Under Total Revenue and Total Cost approach, it is assumed that a producer would be at equilibrium at a point where he is earning maximum profits. Accordingly, his equilibrium is struck at that level of output, where the difference between Total Revenue and Total Cost is maximum.
