The business case of a network that serves both public safety and commercial subscribers

Deploying a single nationwide broadband wireless network to serve all public safety users would have great advantages over the existing fragmented public safety systems. A nationwide system could be created to serve both public safety and commercial subscribers, which would allow a provider to exploit important economies but force it to meet the more costly requirements of public safety. This paper analyzes the viability of a public-private partnership that serves public safety and commercial subscribers from a for-profit provider's perspective. A model is presented that estimates the net present value (NPV) of a wireless network by calculating costs based on the number of cell sites required and revenue based on the projected number of subscribers acquired. The model is applied to both a network that serves only commercial subscribers on 10 MHz of 700 MHz spectrum and a public-private partnership that serves commercial subscribers and public safety personnel on 20 MHz of 700 MHz spectrum. It is found that NPV is greater for the public-private partnership than for the commercial-only network for any population density, which shows that the value of 10 MHz of spectrum exceeds the cost of meeting public safety requirements. Furthermore, the paper demonstrates that NPV/cell increases with population density, so urban areas are profitable and rural areas are unprofitable. The paper demonstrates that a partnership covering 94% of the US population breaks even because the most urban 56% of population subsidizes coverage for the next 38%. If initial deployment is subsidized, a financially sustainable public-private partnership can serve much more than 94%. Additionally, it is shown that allowing urban municipalities to opt-out of the partnership can significantly increase the subsidies required.     

Spectrum management reform: Rethinking practices

Unparalleled growth in wireless communications has increased the pressure for more spectrum to support more users, more uses and more capacity. To alleviate that pressure, major regulatory changes were introduced in several countries in two key areas of spectrum management, namely spectrum assignment and allocation. This paper analyzes those changes and discusses strategies and tactics for deregulating the use of radio spectrum. Spectrum management reforms are considered within the theoretical framework of transition economics, which is concerned with optimal reform speed and sequencing. The paper shows how Anglo-Saxon and European countries have been implementing gradual reforms. Meanwhile, Central American reformers have chosen a fast transition from command-and-control regulation to market mechanisms. Transition economics is used to evaluate the advantages and drawbacks of different spectrum reform strategies.     

Spectrum auction design: Simple auctions for complex sales

Following the successful PCS Auction conducted by the US Federal Communications Commission in 1994, auctions have replaced traditional ways of allocating valuable radio spectrum. Spectrum auctions have raised hundreds of billion dollars worldwide and have become a role model for market-based approaches in the public and private sectors. The PCS spectrum was sold via a simultaneous multi-round auction, which forces bidders to compete for licenses individually even though they typically value certain combinations. This exposes bidders to risk when they bid aggressively for a desired combination but end up winning an inferior subset. Foreseeing this possibility, bidders may act cautiously with adverse effects for revenue and efficiency. Combinatorial auctions allow for bids on combinations of licenses and thus hold the promise of improved performance. Recently, a number of countries worldwide have switched to the combinatorial clock auction to sell spectrum. This two-stage auction uses a core-selecting payment rule. The number of possible packages a bidder can submit grows exponentially with the number of licenses, which adds complexity to the auction. For larger auctions with dozens of licenses bidders cannot be expected to reveal all their valuations during such an auction. We analyze the impact of two main design choices on efficiency and revenue: simple “compact” bid languages versus complex “fully expressive” bid languages and simple “pay-as-bid” payment rules versus complex “core-selecting” payment rules. We consider these design choices both for ascending and sealed-bid formats. We find that simplicity of the bid language has a substantial positive impact on the auction?s efficiency and simplicity of the payment rule has as a substantial positive impact on the auction?s revenue. The currently popular combinatorial clock auction, which uses a complex bid language and payment rule, achieves the lowest efficiency and revenue among all treatment combinations.     

Spectrum auctions in a thin market: The Korean case

In 2010, the Korean government adopted spectrum auctions and introduced a market mechanism into spectrum management. However, the government has often been confronted with conflicts between diverse policy goals of spectrum auctions. A thin spectrum market, where only three incumbent MNOs bid for spectrum, has led to concerns that the government may fail to maximize revenues.Based on the past experiences in Korea, this paper examines the Korean government's choice of auction rules in the face of conflicting policy goals. This paper also recommends that the government implement the following regulatory reforms and consider the auction related measures to deepen its spectrum market or increase the number of bidders: (i) relaxation of foreign ownership restrictions, (ii) introduction of regional or site-specific spectrum licenses, and (iii) modification of auction formats. Spectrum markets tend to be thin in many countries, and the Korean experience may offer implications for those countries when they implement spectrum auctions.     

Linking customer lifetime value with shareholder value

The measurement of customer lifetime value has become a key issue for developing and maintaining long-term profitable customer relationships. It plays a significant role in customer acquisition and retention decisions. Given the growing importance of creating value for shareholders, market strategies have to be evaluated by their capacity to achieve this goal. Accordingly, both the acquisition and maintenance of customers must result in superior cash flows and augmented shareholder value. However, little attention has been paid to the link between customer lifetime value and shareholder value. The authors of this paper provide a conceptual framework for linking customer lifetime value to shareholder value. It is argued that customers have to be treated as assets that increase shareholder value by accelerating and enhancing cash flows, reducing cash flow volatility and vulnerability and increasing the residual value of the firm.     

Municipal fiber in the United States: A financial assessment

Despite growing interest in broadband provided by municipally owned and operated fiber-to-the-home networks, the academic literature has yet to undertake a systematic assessment of these projects' financial performance. To fill this gap, we utilize municipalities' official reports to offer an empirical evaluation of the financial performance of every municipal fiber project in the U.S. operating in 2010 through 2019. An analysis of the actual performance of the resulting fifteen-project panel dataset reveals that none of the projects generated sufficient nominal cash flow in the short run to maintain solvency without infusions of additional cash from outside sources or debt relief. Similarly, 87% have not actually generated sufficient nominal cash flow to put them on track to achieve long-run solvency. In addition, 73% generated negative nominal cash flow over the past three fiscal years, leaving them poorly positioned to make up their deficits and causing them to fall farther into debt. An assessment based on the net present value of these projects' operating cash flow indicates that 53% of projects would not be on track to breakeven even assuming the theoretical best-case performance in terms of capital expenditures and debt service. Close analysis of these projects’ performance reveals that revenue generation likely plays a more important role in generating cash flow than efficiency in construction costs or operating efficiency.     

Standard essential patents and global ICT value chains with a focus on the catching-up of China

Patents, standards and their combination, standard-essential patents (SEPs), are important in the information and communication technology (ICT) sector, in particular in mobile communication. We argue that SEPs are relevant in macroeconomic development and estimate the effect of a country's SEP portfolio on its value-added trade in global ICT value chains (GVC). We find that SEPs retain a higher share of value-adding domestically and that absorptive capacity is needed to join GVCs. China entered the SEP market late and is catching up rapidly. The trade effect of SEPs on China is different from that on matured economies because of the initially low value of its SEPs.     

Spectrum allocation and its relevance for competition

Spectrum is one of the most important production factors for mobile telecommunications operators. Spectrum policy is paramount as spectrum is a scarce resource allocated by regulatory authorities. Hence, when allocating spectrum and determining the potential use of spectrum, the regulatory authorities have a significant influence on the competitive situation in mobile markets.

NGOs and the creation of value in supply chains

Research Summary: Firms and nongovernmental organizations (NGOs) often collaborate to establish new supply chains. With a formal model, we analyze how NGOs can alleviate market failures and improve supplier economic inclusion while strategically interacting with firms. We account for the specific goals of the NGO and the need to induce collaboration between firms and their suppliers. The analysis reveals a “valley of frustration,” when NGO efforts benefit all actors but only marginally the firm. We also show that more powerful firms might prefer to internalize NGO functions, while firms with lower bargaining power and higher investment requirements are better off collaborating with NGOs. Finally, we study NGOs-firms matching patterns and find that firms with higher bargaining power match with NGOs holding stronger capabilities. Managerial Summary: This article analyzes interactions between firms and nongovernmental organizations (NGOs) aiming to improve the economic inclusion of suppliers or to promote the adoption of specific (e.g., sustainable) practices. For firm executives, this study shows the constraints and benefits associated with working with NGOs, the conditions under which integration of NGO functions is preferable as well as the types of NGOs that offer better prospects for a successful collaboration. For NGO executives, it highlights the need to provide enough economic incentives to firms and suppliers alike to ensure their collaboration and the trade-offs associated with this constraint, in particular, if NGO capabilities are limited. Overall, the study provides a comprehensive understanding of how NGO activities can influence value creation in a vertical value chain.

Assessing holistic economic value for multifunctional agriculture in the US

This study used contingent valuation method to shed light on public preferences on the multifunctional roles of the US agriculture and to present a holistic estimate of the economic value of the nonmarket goods and services of US agriculture. Contingent valuation survey instrument was administered to a sample composed from the Ipsos web-based panel. Fishbein’s model of reasoned behavior and mediation hypothesis were combined to model the relationship between WTP (behavioral intentions) and sets of explanatory variables including attitudes, perceived attributes (about family farms, farmland preservation programs, government involvement in agricultural markets, and ecological state of our world), and socio-demographic profiles. Results show that, while exerting a highly significant impact on WTP, attitudes mediate the effects of the attribute variables on WTP: i.e., the attributes influence WTP directly as well as indirectly through attitudes. The estimated mean WTP was $515 per taxpayer annually. Aggregating individual WTPs across the US taxpayers above 20 years old produces $105 billion, representing a crude estimate of the economic value that the US consumers place on the multifunctional roles of US agriculture.     

Supplier representative activities and customer perceived value in complex industrial solutions

The study of value delivery through complex industrial solutions involves a service-rich deployment of resources, many of which are human. Despite this realization, few studies consider the activities of specific actors in this service-dominant context. Through an exploratory netnography of ten online community discussion boards, this study investigates the link between the activities of supplier representatives and the effects on customer perceived value in complex industrial solutions. The findings reveal four major categories of activity (communication, planning, risk management and coordination) as important sources of intangible value (conceptualized as emotional, social and functional outcomes). The data shows, however, that activities must be executed in a timely, accurate, appropriate and value-added manner. The study compliments research in complex industrial solutions through explicit consideration of activities and their relationship with perceived value from a supplier perspective.

Reception-oriented radio rights: Increasing the value of wireless by explicitly defining and delegating radio operating rights

The increasingly intensive coexistence of diverse radio systems and the inability of existing institutions to resolve conflicts in a timely manner require a change in the way operating rights are defined, assigned, and enforced. This paper proposes a regulatory approach that increases delegation to operators and reduces ambiguity by (1) more clearly defining operating rights and harmful interference using the Three P approach of probabilistic reception protections and transmission permissions; (2) facilitating transactions by limiting the number of parties to a negotiation, only altering the rights in a license at renewal, and implementing a registry; and (3) making rights enforcement more efficient by enabling direct enforcement of rights, separating rulemaking from adjudication, and defining remedies up-front.

Wi-Fi as a Commercial Service: New Technology and Policy Implications

While Wi-Fi has enjoyed explosive growth and deployment for use in residential homes, the rollout of commercial Wi-Fi service has been more limited. Part of the holdback on large-scale commercial deployment has been the strategic concern that the commons model to spectrum management lacks the incentives for service providers to invest due to the limited ability to manage interference in the unlicensed band. Today, however, this situation appears to have changed. To explain the new confidence by service providers in commercial Wi-Fi, the activities of the Wi-Fi Alliance and IEEE 802.11 standards body are analyzed to show how these groups essentially replicate many, but not all, of the functions traditionally employed by an effective band manager that is optimizing efficiency on a licensed spectrum block more typically associated with the deployment of commercial services. Consequently, with the Wi-Fi ecosystem functioning as an effective spectrum manager, it is concluded that the service provider investment in Public Wi-Fi networks is rational and the risk posed by saturation or overuse has been reduced to an acceptable level. The strategic implications of this finding on the Wi-Fi platform are the examined. How the requirements from service providers are already significantly influencing the evolution of the Wi-Fi standard is discussed, and an attempt is made to address the risks and liabilities associated with the unlicensed spectrum management model. Thus, service providers increasingly need functionality in Wi-Fi technology to manage interference, and monitor and improve network performance. The current ideas under discussion are elaborated for the next version of Wi-Fi to support both commercial Wi-Fi requirements, which address the interference concerns, but only up to a point, as the unlicensed model intrinsically leaves some risk to participants of spectrum saturation through overuse.
