Profit Maximisation Model

Profit Maximization model helps to predict the price-output behavior of a firm under changing market conditions like tax rates, wages and salaries, bonus, the degree of availability of resources, technology, fashions, tastes and preferences of consumers etc. It is a very simple and unambiguous model. It is the single most ideal model that can explain the normal behavior of a firm. It is often argued that no other alternative hypothesis can explain and predict the behavior of business firms better than profit-maximization hypothesis. This model gives a proper insight in to the working behavior of a firm. There are well developed mathematical models to explain this hypothesis in a systematic and scientific manner.
Profit-maximization implies earning highest possible amount of profits during a given period of time. A firm has to generate largest amount of profits by building optimum productive capacity both in the short run and long run depending upon various internal and external factors and forces. There should be proper balance between short run and long run objectives. In the short run a firm is able to make only slight or minor adjustments in the production process as well as in business conditions. The plant capacity in the short run is fixed and as such, it can increase its production and sales by intensive utilization of existing plants and machineries, having over time work for the existing staff etc. Thus, in the short run, a firm has its own technical and managerial constraints. But in the long run, as there is plenty of time at the disposal of a firm, it can expand and add to the existing capacities, build up new plants, employ additional workers etc to meet the rising demand in the market. Thus, in the long run, a firm will have adequate time and ample opportunity to make all kinds of adjustments and readjustments in production process and in its marketing strategies.
It is to be noted with great care that a firm has to maximize its profits after
