This paper is concerned with the merits of employing market forces to address the issues of wireless spectrum congestion and the allocation of spectrum between firms seeking licensed and unlicensed spectrum rights. We show that when unlicensed spectrum is assigned to all competing users during periods of excess demand an inefficient outcome related to the(More)
This paper evaluates the use of static cost proxy models in setting forwardlooking prices, such as the prices set according to the FCC’s TELRIC methodology. First, it compares the time paths of prices and depreciation under traditional regulatory accounting with the prices and depreciation implied by various versions of TELRIC. When TELRIC prices are(More)
This paper considers the profit maximization problem of a firm that must make sunk investments in long-lived assets to produce output. It is shown that if per period accounting income is calculated by using a particular allocation rule for investment called the relative replacement cost (RRC) rule, that, in a broad range of plausible circumstances, the(More)
The House and Senate of the United States Congress recently passed legislation that directs the FCC to establish a system for using auctions to allocate the use of radio spectrum for personal communications services (PCS). There is a unique and unprecedented set of issues that arise in this context, which are of interest to economists, industry analysts,(More)
Cost allocation problems arise in many contexts in economics and management science. In a typical problem that we have in mind, a decision maker must decide how to allocate the joint cost of production among several commodities using prices. Furthermore, these prices must satisfy certain reasonable postulates among which is the requirement that total(More)
OBJECTIVES To examine the accuracy of standard trauma-room chest x-ray films in assessing blunt abdominal trauma and to determine the significance of missed injuries under these circumstances. DESIGN A retrospective review. SETTING A regional trauma unit in a tertiary-care institution. PATIENTS Multiply injured trauma patients admitted between January(More)
The ability of level I trauma units to operate efficiently may be hampered by the presence of a number of patients with an excessive length of stay (LOS). In an attempt to determine causes for and suggest potential solutions to the long-term occupation of beds in an acute care trauma facility, the cases of patients with extended LOSs in a level I trauma(More)
With competition in telecommunications markets a carrier relies on competing networks to complete inter-network calls originated by its customers. Regulators typically require the calling party’s network to pay a termination fee to the called party’s network equal to the terminating network’s “incremental cost” of completing the call. The payments for such(More)
