Enforcement and Spectrum Sharing: Case Studies of Federal-Commercial Sharing

To promote economic growth and unleash the potential of wireless broadband, there is a need to introduce more spectrally efficient technologies and spectrum management regimes. That led to an environment where commercial wireless broadband need to share spectrum with the federal and non-federal operations. Implementing sharing regimes on a non-opportunistic basis means that sharing agreements must be implemented. To have meaning, those agreements must be enforceable.\ud \ud With the significant exception of license-free wireless systems, commercial wireless services are based on exclusive use. With the policy change facilitating spectrum sharing, it becomes necessary to consider how sharing might take place in practice. Beyond the technical aspects of sharing, that must be resolved lie questions about how usage rights are appropriately determined and enforced. This paper is reasoning about enforcement in a particular spectrum bands (1695-1710 MHz and 3.5 GHz) that are currently being proposed for sharing between commercial services and incumbent spectrum users in the US. We examine three enforcement approaches, exclusion zones, protection zones and pure ex post and consider their implications in terms of cost elements, opportunity cost, and their adaptability

The Effect of Firm Characteristics on the Use of Percentage Retail Leases

Choice of lease payments has been widely studied in the literature. There are three—not necessarily exclusive—explanations that have received attention. The first attributes the choice of fixed versus percentage lease payments to risk-sharing preferences. The second explanation views percentage-of-sales lease agreements as a way discriminating monopolists can appropriate economic rents. The third attributes percentage-of-sales lease agreements to a metering and bonding argument. This paper examines the proposition that the choice of percentage retail leases is driven in part by managements\u27 desire to circumvent the cost of violating debt covenant restrictions. The evidence presented here supports the prediction that retail firms with higher debt–asset ratios are more likely to adopt percentage lease agreements
