The Environmental Impact of Internet Regulation

Abstract : We address the need to regulate Internet infrastructure usage to take into account environmental externalities. We model the interactions between a monopoly ISP and different types of content providers in settings where the former chooses the network size and the latter influences congestion on the network. We first show that current net neutrality regulation does not provide agents the right incentives to cope with the environmental externality issue. Then, we study several alternatives, including laissez-faire, price-based regulation, and norm-based regulation. We derive conditions under which these alternatives fare better than net neutrality. In particular, the two types of regulations are useful tools to accommodate consumer interest and environmental concerns.
