Lewellen, Long, and McConnell [13] have demonstrated that in a perfect market competitive market equilibrium lease payments will be determined such that the lease or buy choice will be a matter of indifference (p. 790). They conclude that there may exist market imperfections such as tax rate differentials between lessors and lessees, differences in realizable depreciation deductions and salvage values, and different borrowing possibilities, which may lead to exploitable opportunities by lessors and lessees.
