1. Internet Economics - Bailey, Joseph P.
The Internet, a growing network of networks, is an often touted and often misunderstood technology. It has its own infrastructure complete with service providers, private networks, user communities, international links, etc. similar to telephone or telegraph industries. However, the Internet is more decentralized and less application-specific than traditional telecommunication industries. These differences extend beyond the technology of the Internet to the economics and policies. This paper explores Internet economics, a growing field which encompasses the technology, economics, and policy surrounding the Internet. It identifies different communities who have overlapping interests in this field and how their preconceived notions of how the Internet operates create contradictory views on how this...

2. Opening the Set-Top Market - Bailey, Joseph P.
As the cable television networks transition from a broadcast-only network, to a high-bandwidth two-way network, the importance and functionality of the set-top box increases. However, developments in the set-top box industry have been restrained by the control the cable companies have over their equipment. Currently, a set-top box includes closed, proprietary technology which prohibits its use on other cable systems' networks. This paper explores the possibility of abandoning closed, proprietary set-top box standards in favor of open standards. This "opening" of the set-top box is not a trivial matter since it challenges cable companies' concerns about security, quality, etc. The paper includes a policy analysis of the impact...

3. Internet Economics: What Happens When Constituencies Collide? - Bailey, Joseph P.; McKnight, Lee
This paper describes the emerging field of Internet Economics and some of the constituencies which are shaping it. It defines the motivating factors for looking at this area, reviews some recent research results, and explores areas of overlapping interest. The paper concludes with six recommendations for further work. different academic disciplines which have done work related to Internet economics: technology, economics, and policy. Each of these areas has important contributions to make to the field but there has been little consensus across disciplines (or even within disciplines) on which direction to take. Figure 1 shows a Venn diagram which tries to characterize the constituencies' current motivation to look at Internet economics.

4. The Impact of Regulation on Sustainable Infrastructure Competition and Investment in Advanced Communications Services: A Comparative Analysis of Regulatory Frameworks in America and the European Union - Kiessling, Thomas

5. A Contribution to the Understanding of Illegal Copying of Software: Empirical and Analytical Evidence Against Conventional Wisdom - Osorio, Carlos A.
This paper analyzes the causes of illegal copying and its effects in the software market across 66 countries. By studying the aggregated and joint effects of different variables, the analysis shows that supply constraints in the software market, shortage of after-sale support, and characteristics legal framework are major drivers of illegal copying when controlling for income per capita. It also concludes there is enough evidence to show there is a threshold of illegal copying over which its aggregated effect on the software market is positive, and this is an efficient mechanism for market creation. Thus, allowing illegal copying in some countries and at certain periods of...

6. Availability of Broadband Internet Access: Emperical Evidence - Gillett, Sharon Eisner; Lehr, William

7. A Game Theoretic Modeling and Analysis for Internet Access Market - Correa, Hector; Weiss, Martin; Shin, Seung-Jae
In this paper, we study the local dial-up Internet access market using a game theoretic model. In particular, we consider the Nash equilibrium of the service providers and examine their behavior on investment and output level. We calibrate this model to fit the industry structure and data found in rural markets. In the first part of the paper, we examine the Internet industry structure and its characteristics. In the latter part of the paper, we create an abstract Cournot duopoly model, in which real world cost and revenue projection will be used to find an Internet access market equilibrium and its social welfare. These analyses allow...

8. The Application of IP Telephony to Local Exchange Carriers - McGarty, Terrence

9. Internet Interconnection Economic Model and its Analysis: Peering and Settlement - Shin, Seung-Jae; Weiss, Martin
Peering and transit are two types of Internet interconnection among ISPs. Peering has been a core concept to sustain Internet industry. However, for the past several years, many ISPs broke their peering arrangement because of asymmetric traffic pattern and asymmetric benefit and cost from the peering. Even though traffic flows are not a good indicator of the relative benefit of an Internet interconnection between the ISPs, it is needless to say that cost is a function of traffic and the only thing that we can know for certain is inbound/outbound traffic volumes between the ISPs. In this context, we suggest Max {inbound traffic volume, outbound traffic volume} as...

10. The Internet Protocol (IP) and Global Telecommunications Transformation - McGarty, Terrence

11. A Proposal for Efficient Use of the Television Spectrum - Weiss, Martin
It is widely recognized that broadcast spectrum is utilized inefficiently. The principle technical cause of this inefficiency is inexpensive receiver design. In addition, the economics of the industry are such that users do not pay the opportunity costs of spectrum associated with these receivers. In this paper, I develop an approach that would internalize the spectrum opportunity costs so that consumers will make decisions that are economically more rational in terms of their choice of the program delivery channel.

12. Wireless Local Loop in Developing Regions: Is It Too Soon For Data? - Kibati, Mugo; Krairit, Donya

13. Committee Jurisdiction and Internet Intellectual Property Protection - deFigueiredo, John
This paper examines the impact of increasingly common congressional committee jurisdictional turf wars on policy outcomes. It develops a theoretical model that shows how legislators balance the benefits of expanded committee jurisdiction against preferred policy outcomes, yielding predictions that are different from the traditional committee-dominance theories. The theory predicts that a) senior members, and members who are in safe districts are most likely to challenge another committee's jurisdiction; b) policy proposals may be initiated off the proposer's ideal point in order to obtain jurisdiction over an issue; c) in many cases, policy outcomes will be more moderate with jurisdictional fights than they would be without these turf...

14. Interconnection Payments in Telecommunications: A Competitive Market Approach - Gabel, David
In this paper, we first discuss the concept of "Bill-and-Keep" whereby the party that receives a call pays for receiving the call. We explore if this outcome is efficient and consistent with competitive markets. Following the discussion of Bill-and-Keep we offer an explanation of why the flow of traffic has been imbalanced between incumbent local exchange carriers (ILECs) and competitive local exchange carriers (CLECs). We explain that this outcome is the natural outcome of the barriers to entry created by the incumbents in their refusal to provide collocation to internet service providers (ISPs).

15. Optical Networks and the Future of Broadband Services - Lehr, William; McKnight, Lee; Ferreira, Petro
The evolution of broadband services will depend on the widespread deployment of optical networks. The deployment of such networks will, in turn, help drive increased demand for additional capacity. In this world, service providers will have a growing need to be able to flexibly adjust capacity to accommodate uncertain and growing demand. In this article, we present a cost model that highlights the advantages of new optical networking technologies such as Dense Wavelength Division Multiplexing (DWDM) over traditional architectures for optical networks. This analysis highlights the increased flexibility and scalability of DWDM networks, which lowers the deployment costs of such networks in light of growing and uncertain demand. The...

16. Best Effort versus Spectrum Markets: Wideband and Wi-Fi versus 3G MVNOs? - McKnight, Lee; Linsenmayer, Raymond; Lehr, William
This paper asks is whether (i) 3rd generation wireless services, as embodied in the planned and soon to be offered services emerging first in Asia and Europe, or (ii) the unlicensed wireless services such as 802.11 or wi-fi but also including more advanced wideband and ultrawideband (UWB) services which are being experimented with primarily in North America, offer more compelling visions for advanced wireless services. we conclude that secondary spectrum markets are important for the viability of the 3G industry, and not only for reasons of efficiency. One large difference between 2G and 3G networks, observed in our models, was that voice services alone would not generate sufficient...

19. Show Me the Money: Contracts and Agents in the Service Level Agreement Markets - McKnight, Lee; Lehr, William
Delivering real-time services (Internet telephony, video conferencing, and streaming media as well as business-critical data applications) across the Internet requires end-to-end quality of service (QoS) guarantees, which requires a hierarchy of contracts. These standardized contracts may be referred to as Service Level Agreements (SLAs). SLAs provide a mechanism for service providers and customers to flexibly specify the service to be delivered. The emergence of bandwidth and service agents, traders, brokers, exchanges and contracts can provide an institutional and business framework to support effective competition. This article identifies issues that must be addressed by SLAs for consumer applications. We introduce a simple taxonomy for classifying SLAs based on the identity of...
