No. of bitstreams: 1 DynamicCoordinationWithNetworkExternalities.pdf: 394741 bytes, checksum: e157b70d33e77a4676224e1c72a1e34d (MD5) Previous issue date: 2018-05-09 / I analyze a dynamic coordination model under quasi-hyperbolic discounting. The main result is that present bias can induce a society to coordinate efficiently. When considering a transition from network A to B, higher present bias induces individuals to ask for higher relative quality of B, which is also what the central planner dictates, but for different reasons. Present biased agents overvalue relative quality, as positive externalities coming from more individuals in network B are more distant in the future, because transitioning takes time. The planner's motives are the negative externalities inflicted on agents 'stuck' in A during a transition. / É analizado um modelo de coordenação dinâmica sob desconto quasi-hiperbólico. O resultado principal é que a presença de miopia temporal pode induzir uma sociedade a coordenar eficientemente. Considerando a transição de uma rede A para uma rede B, maior miopia temporal induz indivíduos a serem mais exigentes em termos de qualidade intrínseca relativa da rede B, o que é a mesma coisa que um planejador central ditaria, mas por razões diferentes. Indivíduos com miopia temporal valorizam excessivamente a qualidade relativa, pois as externalidades recebidas por haver muitos indivíduos na rede B estão em um futuro distante e as transições não são imediatas. Os motivos da sugestão do planejador central são as externalidades negativas infligidas em agentes 'presos' na rede A durante uma transição.

Ela investiga especificamente como se comportou, depois da regulação, a participação de mercado das prestadoras de serviço em diferentes localidade do país. O principal questionamento realizado é se, no momento da transição, quando os entraves econômicos percebidos pelos usuários diminuíram, a concentração de mercado caiu ou se a presença de promoções em tarifas de ligações efetuadas dentro de uma mesma rede eventualmente induziu o comportamento inverso. / This thesis evaluates what were the results of the introduction of portability in the Brazilian mobile market trying to understand what were the factors that influenced this process negatively. It specifically investigates how the market share of service providers behaved after regulation in different location of the country. The main question been made is whether, at the time of transition, when economic barriers perceived by users decreased, market concentration has fallen or if the presence of discounts on fares of calls within the same network eventually induced the opposite pattern.
