This paper reviews the small but growing economic literature on network neutrality. It considers a number of possible departures from network neutrality, in particular termination fees, second-degree price discrimination, and vertical foreclosure.

We review and model the impact of the internet on the production and uptake of high-quality news. Our review of trends in the market for news suggests three stylized facts: i) particular quality news markets are dominated by merely a few providers, ii) demand for quality news appears stable, but provision of news has become specialized; mainstream news is decoupled from quality news, and iii) the dominant business model of internet news mirrors that of radio, television, and newspapers in that costs of news production are recouped via advertising. We build a stylized model that rationalizes these facts. Our model captures three conflicting effects: (1) economies of scale in the production of news lead to monopolies on particular markets, (2) easy access to information on the internet makes it cheaper to provide high-quality news and to disseminate it via the web, which increases the production of such news; and (3) the existence of bloggers and news aggregators who recycle the stories of news-providers reduces the effective property rights of high-quality news producers, thus forcing the business model of the internet to be advertising-based. For the most likely cases, our model would imply that the internet does not constitute bad news for the provision and uptake of quality news.

Payment cards continue to replace cash and checks in advanced economies. Along with the growth of payment card transactions has come greater scrutiny by public authorities of certain payment network rules along with the level of certain fees. This article reviews the growing payment card literature and discusses the impact of several regulatory interventions on card adoption, usage, and social welfare.

We empirically demonstrate a practical approach of efficiency evaluation with limited data availability in some regulated industries. We apply PCA-DEA for radial efficiency measurement to U.S. natural gas transmission companies in 2007. PCA-DEA reduces dimensions of the optimization problem while maintaining most of the variation in the original data. Our results suggest that the methodology reduces the probability of over-estimation of individual firm-specific performance.
