    Abstract: This survey paper analyses some of the fundamental economic and management science issues concerning the communications and information economy ,with special emphasis on mobile communications. Are first highlighted major trends such as the balkanisation of the communications networks , and the advent of competitive tariffs. This leads to a move away from time and distance based charges to tariffs covering bandwidth, service , and contents use. It is noted that very few resources have gone into the analysis of that sector and its inter-relations with others. The paper advocates for more visibility and research into the unique aspects of the communications and information sector. It does so by making an inventory of key economics ,management, and computational economics research issues in need of contributions, selected from the following areas: public communications infrastructure and tariffing principles, sales of communications services, public access and equal access policies, competitive access pricing, communications industry finance, engineering-economic studies, information contents and macroeconomic issues. Finally , the specific aspects of models of the communications and media sector are addressed in view of modelling work. This includes variables, pricing and production models for both communications and information contents . The most unique contribution is here a formal model for quantifying and pricing knowledge , both for consumption and for assets building .

    Abstract: We investigate social circles in intra-firm settings. First, we argue that social circles are inhabited by individuals whose attitudes display fit with the objectives of the social circle rather than more self-centered instrumentalism or calculation. For a test of this hypothesis, we distinguish between friendship circles and strategy-influence circles. We find that friendship circle membership is positively associated with attitudes that display empathic concern but negatively with more instrumental attitudes, whereas strategy-influence circle membership is positively associated with attitudes that display long-term ambition but negatively with attitudes that display short-term calculation. Second, we argue and find that membership of social circles affects individual performance (social circles foster the exchange of information, for which we find clear evidence), albeit not necessarily in a linear fashion. Our new insights into social circle membership and performance implications can guide individuals in seeking access to such social circles and can aid management in understanding and perhaps influencing intra-firm knowledge flows.
