Online Appendix: Ideological Segregation Online and Offline

In table 2 we present standard errors for our main estimates. For estimates that come from MRI, the GSS or the CNES, we compute standard errors through a nonparametric bootstrap over samples of respondents. For estimates that come from comScore aggregate data, that is not an option. Instead we perform a parametric bootstrap in which we model the share conservative of each website as an independ...

Offline and Online Facility Leasing

We study the problem of leasing facilities over time, following the general infrastructure leasing problem framework introduced by Anthony and Gupta [1]. If there are K different lease types, Anthony and Gupta give an O(K)-approximation algorithm for the problem. We are able to improve this to a 3-approximation algorithm by using a variant of the primal-dual facility location algorithm of Jain ...

Ideological Segregation Online and Offline∗

We use individual and aggregate data to ask how the Internet is changing the ideological segregation of the American electorate. Focusing on online news consumption, offline news consumption, and face-to-face social interactions, we define ideological segregation in each domain using standard indices from the literatureonracial segregation.

Offline to Online Conversion

We consider the problem of converting offline estimators into an online predictor or estimator with small extra regret. Formally this is the problem of merging a collection of probability measures over strings of length 1,2,3,... into a single probability measure over infinite sequences. We describe various approaches and their pros and cons on various examples. As a side-result we give an elem...
