each firm (the business cost times the amount provided by the firm). The benefit of each firm is then this income short the expense of creating the result. Obviously, there is an essential reliance between the two firms. Assuming one firm fluctuates its result, this will thusly influence the market cost thus the income and benefits of the other firm. We can characterize the result work which gives the benefit of each firm as a component of the two results picked by the organizations. Cournot accepted that each firm picks its own result to amplify its benefits given the result of the other firm. The Nash balance happens when the two firms are creating the results which augment their own benefit given the result of the other firm
