This paper examines current hypotheses about Internet accessibility and how it will meet the needs of an increasing audience without decreasing service. A pricing system for the Internet may be sufficiently elastic to reduce congestion and allow for distributional equity.

This paper aims to broadly discuss a subject that intends to be an interface between the economics and the management of the firm: the Enterprise Architecture. This concept is viewed here as the most appropriate means to understand the impact of the information content, of the information systems, and of the information and communication technologies-ICTs on the internal technological and organizational choices of the firm. In support to this argument it relies on three main steps. Initially, a brief review of the main theories (economic and management) of the firm is made highlighting their contributions, caveats and convergences. Then the paper bases its analysis on the concept of the firm as an "engine of information" and on a concept from the Computing Science and Engineering, Enterprise Architecture, to point out that these concepts bring up important contributions towards a more consistent interpretation of what the firm is (or how it is organized) currently, in which is practically impossible to exist without the modern information tools. Finally, it is presented an innovative methodology, in an analogy to the Structure-Conduct-Performance Paradigm (that is traditionally used on the empirical market analysis), which identifies the firm according to three linear connected approaches: its architecture, its governance, and its growth strategy.

Analytics (discover and communication of patterns, with significance, in data) of Big Data (basically characterized by large structured and unstructured data volumes, from a variety of sources, at high velocity - i.e., real-time data capture, storage, and analysis), through the use of Cloud Computing (a model of network computing) is becoming the new “ABC” of information and communication technologies (ICTs), with important effects for the generation of new firms and for the restructuring of those ones already established. However, as this chapter argues, successful application of these new ABC technologies and tools depends on two interrelated policy aspects: 1) the use of a proper model which could help one to approach the structure and dynamics of the firm, and, 2) how the complex trade-off between information technology (IT) and communication technology (CT) costs is handled within, between and beyond firms, organizations and institutions.
