Suppose that firms face a 40% income tax rate on all profits. In particular, losses receive full credit. Firm A has a 50% probability of a $1000 profit and a 50% probability of a $600 loss each year. Firm B has a 50% probability of a $300 profit and a 50% probability of a $100 profit each year.a.
Suppose that firms face a 40% income tax rate on positive profits and that net losses receive no credit. (Thus, if profits are positive, after-tax income is (1− 0.4) × profit, while if there is a loss, after-tax income is the amount lost.) Firms A and B have the same cash flow distribution as in
