本文提供了证据的投入和产出的市场缺陷的经验分离。我们指定了一个银行竞争模型，同时估计银行在输出（贷款）和输入（存款）市场的行为。我们的研究结果表明，企业在贷款和存款市场上都表现出一定程度的非竞争行为。而且，我们发现输入侧和输出侧是经验上可分离的，也就是说，市场一侧的市场势力的度量不受假设市场另一侧完全竞争的影响。我们的研究结果表明，集中在输入侧或输出侧的市场势力的实证研究是不受显着的误指定错误。
This paper provides evidence on the empirical separability of input and output market imperfections. We specify a model of banking competition and simultaneously estimate bank conduct in output (loan) and input (deposit) markets. Our results suggest that firms display some degree of non-competitive behavior in both the loan and the deposit markets. Moreover, we find that the input side and the output side are empirically separable, that is, the measurement of market power on one side of the market is not affected by assuming that the other side of the market is perfectly competitive. Our results suggest that empirical studies of market power that concentrate on either the input side or the output side are not subject to significant misspecification error.
