众所周知,搜索成本和转换成本可以通过限制消费者更换供应商的能力来创造市场力量。虽然以前的研究单独检查了每种成本,但本文证明了同时检查这两种摩擦的好处。这篇论文展示了这两种成本之间的细微差异如何在其对消费者行为、竞争和福利的影响方面产生重要差异。此外,本文还举例说明了一种简单的经验方法,用于估计两种成本的不同衡量标准,同时证明了如果只考虑一种成本可能会出现潜在的偏差。
It is well known that search costs and switching costs can create market power by constraining the ability of consumers to change suppliers. While previous research has examined each cost in isolation, this paper demonstrates the benefits of examining the two types of friction in unison. The paper shows how subtle distinctions between the two costs can provide important differences in their effects upon consumer behaviour, competition and welfare. In addition, the paper also illustrates a simple empirical methodology for estimating separate measures of both costs, while demonstrating a potential bias that can arise if only one cost is considered.
