  • The 2016–2018 triennium was a period marked by a fierce dispute between the European Commission and Autoridade Nacional de Comunicações, Portugal, on the need to regulate wholesale access prices. While the European Commission defended the imposition of Fiber-To-The-x regulation in non-competitive areas, the Portuguese sectoral regulator argued in favor of the persistence of Fiber-To-The-x deregulation. Following a Game Theory approach, the present study demonstrates that the transition from Fiber-To-The-x deregulation to Fiber-To-The-x regulation should only occur when a given territorial unit becomes a competitive area since the subgame perfect Nash equilibrium captures a regulatory framework optimally characterized by the imposition of active access price deregulation (regulation) in non-competitive (competitive) areas, that is, local administrative units characterized by a weak (strong) degree of vertical spillover, respectively. Meanwhile, ducts access regulation must be permanently imposed throughout the national territory, despite it can be relaxed in competitive areas if the regulator imposes intra-flexibility to establish a monopolistic bottleneck to ensure social welfare maximization. Previous conclusions require to introduce both facility-based and service-based competition at the entry stage as well as active and passive obligations at the regulation stage in a multi-stage game with complete information. The present analysis legitimizes the emergence of a new optimization theory in the telecommunications literature, whose modus operandi is contrary to (coincident with) the ladder of investment theory in non-competitive (competitive) areas, respectively. Differently from the view sustained by the ladder of investment theory, which defends that a short-term regulatory touch combined with long-term market deregulation is a socially optimal strategy, the new theory confirms that a regulatory intervention is socially desirable only in the long run. The conceptual refinement is meticulously explained and labeled as the theory of creative creation because, differently from the Schumpeterian gale of creative destruction, whose processes of industrial mutation are permanently market-driven by assumption, a period of regulatory holidays followed by successive regulatory interventions dependent on the degree of vertical spillover observed in the telecommunications industry can effectively promote investment realization that continuously revolutionizes the market structure from within, incessantly destroying the old technology. The theory of creative creation reflects the regulatory framework currently in force in the Portuguese Telecommunications Industry.

Gray line represents the number of facility-based firms that would be sustained in case of FTTx regulation in the subdomain $ 0\leq\beta<0.4476. $ Black (Blue) line represents the number of facility-based firms in C areas when the duopolistic bottleneck with asymmetric downstream access (monopolistic bottleneck) is sustained in equilibrium, respectively

    Figure 2.  Equilibrium wholesale access prices. Red (Blue) [Black] lines represent the parameter space where the triopoly (monopolistic bottleneck) [duopolistic bottleneck with asymmetric downstream access] is sustained in equilibrium, respectively. Continuous (Dashed) lines represent the regulated active access price (ducts access fee), respectively. The plot assumes $ a = 1 $

    Figure 3.  Equilibrium investment level of the facility-based operators. Red (Blue) [Black] lines represent the parameter space where the triopoly (monopolistic bottleneck) [duopolistic bottleneck with asymmetric downstream access] is sustained in equilibrium, respectively. Continuous (Dashed) [Dotted] lines represent investment level of the incumbent (first alternative facility-based) [second alternative facility-based] operator, respectively. The right middle panel compares the profit level of the facility-based competitors I and N. Gray lines represent the investment level that would be achieved if FTTx regulation were adopted in the subdomain $ 0\leq\beta<0.4476 $. The last subplot captures the total amount of investment in the telecommunications industry. The plot assumes $ a = 1 $

Red (Blue) [Black] lines represent the parameter space where the triopoly (monopolistic bottleneck) [duopolistic bottleneck with asymmetric downstream access] holds in equilibrium, respectively. Continuous (Dashed) [Dotted] lines represent retail prices and market share of the incumbent (alternative facility-based) [alternative service-based] operator, respectively.
