摘要

平台使用价格平价条款来防止卖家在通过其他渠道销售时设定更低的价格。他们声称，这些限制是必要的，这样平台就有动力投资提供搜索服务——如果没有这些限制，消费者会在平台上搜索，但随后会转向更便宜的渠道购买。在包含这些影响的模型中，我们发现宽的价格平价条款会导致平台投资过多，而窄的（或无）价格平价条款则会导致平台投入不足。考虑到这些投资效应，广义价格平价条款降低了消费者盈余，但对总福利的影响不明确。

Platform Investment and price parity clauses*

Platforms use price parity clauses to prevent sellers setting lower prices when selling through other channels. They claim these restraints are needed so platforms have incentives to invest in providing search services—without them, consumers would search on the platform but then switch to buy in a cheaper channel. In a model incorporating these effects, we find that wide price parity clauses lead to excessive platform investment while narrow (or no) price parity clauses lead to insufficient platform investment. Taking these investment effects into account, wide price parity clauses lower consumer surplus but have ambiguous effects on total welfare.

期刊介绍： First published in 1952, the Journal of Industrial Economics has a wide international circulation and is recognised as a leading journal in the field. It was founded to promote the analysis of modern industry, particularly the behaviour of firms and the functioning of markets. Contributions are welcomed in all areas of industrial economics including: - organization of industry - applied oligopoly theory - product differentiation and technical change - theory of the firm and internal organization - regulation - monopoly - merger and technology policy Necessarily, these subjects will often draw on adjacent areas such as international economics, labour economics and law.
