Reforma regulatória no contexto brasileiro

Esta pesquisa teve por objetivo analisar a potencialidade e obstáculos da adoção da Análise de Impacto Regulatório e do órgão supervisor no contexto brasileiro. Para isso, realizou-se uma pesquisa de campo com representantes de instituições envolvidas com a AIR, com as agências reguladoras e a Casa Civil da Presidência da República, além de especialistas com publicações relativas ao tema. Foram realizadas assim, doze entrevistas semi-estruturadas em torno de perguntas previamente elaboradas a partir dos conhecimentos explorados no referencial teórico do trabalho. Concluiu-se que a partir de um ambiente de preocupação com a qualidade regulatória no Brasil, tanto a esfera mais central da administração – a Casa Civil como os entes reguladores investigados, têm empreendido esforços em prol de um sistema regulatório mais eficaz. Entretanto, há um longo caminho a ser percorrido e diversos obstáculos a serem ultrapassados. Com relação à AIR e ao órgão de supervisão, a resistência, a especialização técnica, o desenho institucional são alguns desses percalços que deverão ser transpostos a fim de que o Brasil alcance de fato uma melhoria da qualidade regulatória

Essays on regulatory risk issues

Most studies around that try to verify the existence of regulatory risk look mainly at developed countries. Looking at regulatory risk in emerging market regulated sectors is no less important to improving and increasing investment in those markets. This thesis comprises three papers comprising regulatory risk issues. In the first Paper I check whether CAPM betas capture information on regulatory risk by using a two-step procedure. In the first step I run Kalman Filter estimates and then use these estimated betas as inputs in a Random-Effect panel data model. I find evidence of regulatory risk in electricity, telecommunications and all regulated sectors in Brazil. I find further evidence that regulatory changes in the country either do not reduce or even increase the betas of the regulated sectors, going in the opposite direction to the buffering hypothesis as proposed by Peltzman (1976). In the second Paper I check whether CAPM alphas say something about regulatory risk. I investigate a methodology similar to those used by some regulatory agencies around the world like the Brazilian Electricity Regulatory Agency (ANEEL) that incorporates a specific component of regulatory risk in setting tariffs for regulated sectors. I find using SUR estimates negative and significant alphas for all regulated sectors especially the electricity and telecommunications sectors. This runs in the face of theory that predicts alphas that are not statistically different from zero. I suspect that the significant alphas are related to misspecifications in the traditional CAPM that fail to capture true regulatory risk factors. On of the reasons is that CAPM does not consider factors that are proven to have significant effects on asset pricing, such as Fama and French size (ME) and price-to-book value (ME/BE). In the third Paper, I use two additional factors as controls in the estimation of alphas, and the results are similar. Nevertheless, I find evidence that the negative alphas may be the result of the regulated sectors premiums associated with the three Fama and French factors, particularly the market risk premium. When taken together, ME and ME/BE regulated sectors diminish the statistical significance of market factors premiums, especially for the electricity sector. This show how important is the inclusion of these factors, which unfortunately is scarce in emerging markets like Brazil.
