|November 2019||The Impact of the General Data Protection Regulation on Internet Interconnection|
with Bradley Huffaker, KC Claffy, Shane Greenstein: w26481
The Internet comprises thousands of independently operated networks, where bilaterally negotiated interconnection agreements determine the flow of data between networks. The European Union’s General Data Protection Regulation (GDPR) imposes strict restrictions on processing and sharing of personal data of EU residents. Both contemporary news reports and simple bilateral bargaining theory predict reduction in data usage at the application layer would negatively impact incentives for negotiating interconnection agreements at the internet layer due to reduced bargaining power of European networks and increased bargaining frictions. Considerable empirical evidence at the application layer confirms this prediction. Using a large sample of interconnection agreements between networks around the w...
|September 2018||Sniff Tests in Economics: Aggregate Distribution of Their Probability Values and Implications for Publication Bias|
with Christopher Snyder: w25058
The increasing demand for rigor in empirical economics has led to the growing use of auxiliary tests (balance, specification, over-identification, placebo, etc.) supporting the credibility of a paper's main results. We dub these "sniff tests" because standards for passing are subjective and rejection is bad news for the author. Sniff tests offer a new window into publication bias since authors prefer them to be insignificant, the reverse of standard statistical tests. Collecting a sample of nearly 30,000 sniff tests across 60 economics journals, we provide the first estimate of their aggregate probability-value (p-value) distribution. For the subsample of balance tests in randomized controlled trials (for which the distribution of p-values is known to be uniform absent publication bias, al...
