- 주제: Interchange fee, market structure, and excessive intermediation in the payment markets.
- Abstract: The rapid technological development in the payment industry has introduced numerous new products, characterized as multi-sided platforms with strong network effects. However, these advancements also bring challenges: one such challenge arises from price coherence on the merchant side, combined with the offering of generous rewards to only a subset of credit card users. This dynamic can lead to excessive use of these cards and undesirable distributional effects. The issue may exacerbate with heightened competition among payment instrument providers. To empirically address these concerns, we have developed and estimated a model with two layers: the upstream market for issuers and acquirers, and the downstream market for consumers and merchants. Through structural parameter estimation, we aim to evaluate the social welfare implications of interchange fee regulation and increased competition in the upstream market.
