摘要/Abstract:
We analyze the impact of a hypothetical data neutrality regulation on the downstream market competition, the platform's incentives to produce data, and consumer welfare. Under data neutrality, all firms that want to access a platform's data are treated equally in terms of data usage, regardless of whether the firm is affiliated with the platform. We show that weak data neutrality, which only requires the amount of data provision to be nondiscriminatory, may have de facto no impact on the market. This is in stark contrast to strong data neutrality, which also regulates that the data prices charged to the affiliated and unaffiliated sellers to be the same. From a welfare perspective, we find that data neutrality, whether it is weak or strong, does not necessarily make consumers better off, because the platform may optimally reduce the amount of data provision in response to the data neutrality regulations.
