The research incorporated water supply and infrastructure costs into the energy model SATIM to better reflect the interdependence of water and energy. (...) As shown by the model, some additional investments in the energy sector can realize significant saving and benefits in the water sector.   More information about this study is available at:   International Energy Agency: http://documents.worldbank.org/curated/en/706861489168821945/Modeling-the-water-energy-nexushow-do-water-constraints-affect-energy-planning-in-South-Africa   Morocco   Morocco has merged the two public utilities in charge of water and electricity: National Office for Potable Water and electricity National Electricity Office.

This could form the basis for further ITU-T Recommendations which are strongly market-related. 3.2 Limits of the model The model attempts to answer the question: Do the additional operations and technical infrastructure required drive higher roaming costs to the levels charged? However, the model has practical limits in its scope and accuracy when attempting to answer this question. (...) For such (arbitrary) conditions, basic cost modelling is less applicable, except to show a comparison of the underlying costs.

One assumption made in the model is that a common set of the high level business processes exist in most MNOs. (...) One example is the move to all IP networking with LTE and away from the packet technology in UMTS 3G networks. 4.1.2 Construct the cost model The roaming model described here will cover the fundamental network elements and process costs of roaming, i.e. the cost of business support services such as customer care and billing. Essentially, the cost model in outline form can be summarized as the underlying MNO costs for roaming (on which data has to be gathered) built up from the business processes.

This paper also contributes to the literature on growth models that are estimated with panel data and climate change variables. (...) The analysis is based on a growth model, applying panel data that includes macroeconomic variables and the frequency and the intensity of disasters. (...) Year-dummy parameters are omitted. 18 ANNEX 2: ROBUSTNESS CHECKS - GROWTH MODELS WITH DIFFERENT CONTROL VARIABLES The growth model remains as presented in the paper, except that the control variables, other than the disaster proxies, are from Barro (2003) and include the same controls as in the main model plus life expectancy, fertility and democracy.

(...) Extra charges for overheads due to international roaming will also reduce with new technology – e.g. with exchange of accounting information via the Internet rather than over the MNO core network. 2.2.5 The physical basis for the model Cost modelling is based on the layout of operator networks and the business support systems (BSS) that implement the roaming process. (...) LTE will tend to follow an evolution of this model, from its switched circuit origins, towards IP packets.
