Abstract:
This paper examines how quality incentives are related to the interoperability of competing plat- forms. Platforms choose whether to operate standardised or exclusively, prior to quality and subsequent price competition. We find that platforms choose a common standard if they can coordinate their quality provision. The actual investment then depends on the cost of quality provision: If rather high, platforms refrain from investment; if rather low, platforms maintain vertically differentiated platforms. The latter case is socially more desirable than exclusivity where platforms do not invest. Nevertheless, quality competition of standardised platforms in- duces the highest investment and maximum welfare.
