Use MM theory to explain the effect of capital structure on the equity cost of capital and WACC a) in perfect markets; and b) when corporate tax exists. (No calculation is needed.)
According To Modigliani Miller approach , The Cost of Capital is independent of its capital structure , The market value of a firm is unaffected is unaffected by the fact that whether a firm is higky levered or has a lower debt component rather the market value of a firm is solely dependent on the operating profits of the company .
Modigliani Miller approach works well in a perfect market
But in the real world capital market , imperfection arises in the capital structure of a firm which affect the valuation
Now we will examine the effect of corporate taxes in the capital structure of a firm along with MM hypothesis . Debt financing is beneficial because interest paid is tax deductible whereas retained earnings or dividend is not tax deductible . So a firm with debts will be higher than the firm with no debts .
