Running Out of Numbers: Scarcity of IP Addresses and What To Do About It

Hidden from view of typical users, every Internet communication relies on an underlying system of numbers to identify data sources and destinations. Users typically specify online destinations by entering domain names (e.g. "congress.gov"). But the Internet's routers forward data according to numeric IP addresses (e.g. 140.147.249.9). To date, the Internet has enjoyed an ample supply of "IPv4" IP addresses, but demand is substantial and growing. Current allocation rates suggest IPv4 exhaustion by approximately 2011. A new numbering system, IPv6, would relieve scarcity, but incentives hinder transition: IPv4 works well for existing networks, and offers easier and simpler access to existing Internet content and services. As a result, to date few networks have begun to support v6. In principle regulators could order networks to implement v6, but the applicable Internet coordinating organizations lack authority or power to force such a transition. In the meantime, a market mechanism for v4 addresses offers important benefits, including allocating scarce v4 addresses to those who need them most, and putting a positive price on v4 space in order to encourage transition to v6. Thus, it seems v4 transfers can help both to mitigate the worst effects of v4 scarcity, and to build the incentives necessary for transition to v6. Read More

When the Internet Runs Out of IP Addresses

Experts predict that within three years we will see the last of new Web addresses. What will happen then? The best solution is to create a market for already assigned but unwanted numbers, says Harvard Business School professor Ben Edelman. Read More

Competition in Modular Clusters

The last 20 years have witnessed the rise of disaggregated "clusters," "networks," or "ecosystems" of firms in a number of industries, including computers, telecommunications, and pharmaceuticals. In these clusters, different firms design and produce the various components of a complex artifact (such as the processor, peripherals, and software of a computer system), and different firms specialize in the various stages of a complex production process. This paper considers the pricing behavior and profitability of these so-called modular clusters. Baldwin and Woodard isolate the offsetting price effects in a model, and show how they might operate in large as well as in small clusters. Read More

A Gentler Capitalism: Black Business Leadership in the New South Africa
