Marginal tax rates under asymmetric taxation

摘要

This paper attempts to analytically determine the impact a tax shield (marginal tax rate) has on the value of a levered firm assuming that gains and losses are taxed differently. Previous research has done this by employing empirical methods and simulation studies. We are able to present closed-form solutions for two popular financing policies. Our solutions reveal that the marginal tax rate is a function with an order greater than one.
