In this paper, an analysis of secondary spectrum market for an OFDM based technology is performed. The potential transactions between three different operators (entrant, medium and incumbent) are considered in three different scenarios: urban, suburban and rural. Based on their business models...

This paper explores the effects of different variables on the price paid for the spectrum by Mobile Service Providers (MSP) in several European countries. Multiple regression analysis is used to find relations between these variables and the Price/MHz/pop, commonly used in the industry to...

This paper explores the effects of Virtual Unbundled Local Access (VULA) –or its absence- on the deployment of Fibre-To-The-Home (FTTH) networks in Spain in a retrospective way. First, we assess the impact of former wholesale broadband markets' regulation on FTTH investment and on the market...

Mobile broadband networks constitute essential infrastructure to enable a wide range of innovative services and use cases anticipated for our digital economy future. Measuring performance is essential in many ways. First, to allow service providers to manage and develop their networks. Second,...

This paper identifies and estimates the relevant cycles in paleoclimate data of earth temperature, ice volume and CO2. Cyclical cointegration analysis is used to connect these cycles to the earth eccentricity and obliquity and to see that the earth surface temperature and ice volume are closely...

A new LM specification procedure to choose between Logistic and Exponential Smooth Transition Autoregressive (STAR) models is introduced. This procedure has better consistency and power properties than that previously available in the literature. Monte-Carlo simulations and empirical evidence...

This paper extends previous work in Escribano and Jorda (1997) and introduces new LM specification procedures to choose between Logistic and Exponential Smooth Transition Regression (STR) Models. These procedures are simpler, consistent and more powerful than those previously available in the...
