A articulação entre regulação, defesa da concorrência e proteção do consumidor nos setores de telecomunicações, energia elétrica e saneamento básico

O objetivo deste relatório é estudar a relação entre proteção ao consumidor, regulação e defesa da concorrência em três setores de infra-estrutura no Brasil: telecomunicações, energia elétrica e saneamento básico. A Seção I deste relatório apresenta uma descrição sintética dos três segmentos selecionados. A Seção II discute aspectos teóricos da relação entre proteção ao consumidor, de um lado, e regulação e defesa da concorrência, de outro, a partir da experiência brasileira e internacional. A Seção III apresenta a experiência brasileira de regulação dos três setores. A Seção IV apresenta algumas estatísticas recentes de reclamações dos consumidores, ainda não suficientemente exploradas pela pesquisa acadêmica. A Seção V discute possíveis configurações institucionais entre proteção ao consumidor, regulação e defesa da concorrência, sugerindo uma explicação para a configuração atual dessas áreas nos três segmentos de infra-estrutura selecionados.

Protecting user privacy in the Cloud: an analysis of terms of service

We present the results of a study that collected, compared and analyzed the terms and conditions of a number of cloud services vis-a-vis privacy and data protection. First, we assembled a list of factors that comprehensively capture cloud companies' treatment of user data with regard to privacy and data protection; then, we assessed how various cloud services of different types protect their users in the collection, retention, and use of their data, as well as in the disclosure to law enforcement authorities. This commentary provides comparative and aggregate analysis of the results.

Relations between regulation, competition policy and consumer protection in telecommunications, electricity and water supply

The purpose of this article is to discuss the relations between regulation, competition policy and consumer protection these relations in three key sectors of Brazil’s infrastructure: telecommunications, electricity and water supply. A study of the literature points to two general principles. First, the need for consumer protection depends on the “degree of sovereignty” enjoyed by consumers, defined in terms of the cost of consumer organization, consumers’ ability to evaluate services, and the level of competition in each sector. Second, the less sovereignty consumers enjoy the more consumer protection institutions are involved with regulation agencies. The evidence for the Brazilian case apparently corroborates these points. In addition, it is important to stress that consumer complaints in regulated sectors seem to have increased more intensely than in others. The article is divided into three sections. Section 1 presents theoretical elements and aspects of the relations between regulation, competition policy and consumer protection evidenced by international experience. Section 2 analyzes the Brazilian experience and in particular the available statistics on consumer complaints about telecommunications, electricity and water supply, submitted to Fundação Procon-SP during the nineties. The last section points to possible configurations of the institutional relations between competition policy, regulation and consumer protection, showing how the existing configuration of these areas in the three infrastructure sectors discussed confirms that the theoretical framework proposed has reasonable predictive power.

Regulation and wage adjustment patterns : non parametric evidence from longitudinal data

This paper gives a first step toward a methodology to quantify the influences of regulation on short-run earnings dynamics. It also provides evidence on the patterns of wage adjustment adopted during the recent high inflationary experience in Brazil.The large variety of official wage indexation rules adopted in Brazil during the recent years combined with the availability of monthly surveys on labor markets makes the Brazilian case a good laboratory to test how regulation affects earnings dynamics. In particular, the combination of large sample sizes with the possibility of following the same worker through short periods of time allows to estimate the cross-sectional distribution of longitudinal statistics based on observed earnings (e.g., monthly and annual rates of change).The empirical strategy adopted here is to compare the distributions of longitudinal statistics extracted from actual earnings data with simulations generated from minimum adjustment requirements imposed by the Brazilian Wage Law. The analysis provides statistics on how binding were wage regulation schemes. The visual analysis of the distribution of wage adjustments proves useful to highlight stylized facts that may guide future empirical work.

Essays on regulation and risk

In this thesis, we investigate some aspects of the interplay between economic regulation and the risk of the regulated firm. In the first chapter, the main goal is to understand the implications a mainstream regulatory model (Laffont and Tirole, 1993) have on the systematic risk of the firm. We generalize the model in order to incorporate aggregate risk, and find that the optimal regulatory contract must be severely constrained in order to reproduce real-world systematic risk levels. We also consider the optimal profit-sharing mechanism, with an endogenous sharing rate, to explore the relationship between contract power and beta. We find results compatible with the available evidence that high-powered regimes impose more risk to the firm. In the second chapter, a joint work with Daniel Lima from the University of California, San Diego (UCSD), we start from the observation that regulated firms are subject to some regulatory practices that potentially affect the symmetry of the distribution of their future profits. If these practices are anticipated by investors in the stock market, the pattern of asymmetry in the empirical distribution of stock returns may differ among regulated and non-regulated companies. We review some recently proposed asymmetry measures that are robust to the empirical regularities of return data and use them to investigate whether there are meaningful differences in the distribution of asymmetry between these two groups of companies. In the third and last chapter, three different approaches to the capital asset pricing model of Kraus and Litzenberger (1976) are tested with recent Brazilian data and estimated using the generalized method of moments (GMM) as a unifying procedure. We find that ex-post stock returns generally exhibit statistically significant coskewness with the market portfolio, and hence are sensitive to squared market returns. However, while the theoretical ground for the preference for skewness is well established and fairly intuitive, we did not find supporting evidence that investors require a premium for supporting this risk factor in Brazil.

Does Regulation matter? Institutional dimension of the 2008 financial crisis

Why did house prices fall in 2007‐2009? This is the fundamental question to most Americans, and to those who lent them money. Most homeowners did not care why residential real estate prices rose. They assumed prices always rose, and they should simply enjoy their good fortune. It was not until prices began to fall that people were left searching for answers. How much did regulation or lack thereof play in the role of the devastation? To what degree did greed and unrealistic consumer expectation have on the real estate bubble? Using existing literature as well as face to face interviews of experienced leaders within the real estate industry in California who experienced both the up and down of the real estate cycle, the overarching purpose of this study is to investigate the opinions and beliefs of the leaders and drivers within the real estate industry about the cause of the real estate bubble that occurred sharply in 2008 . Specifically, this project will focus on the opinions of real estate industry leaders who worked in the center of the subprime universe located in Irvine, California, during 2004‐2008. Comparing the mainstream beliefs with the interviewees it is fair to say that the main finding in the mainstream beliefs are reflected very well with the finding of the subject’s opinion. The thesis is divided into 6 chapters starting with “introduction”, followed by chapter 2 “Literature Review”. Chapter 3 is “Research Methodology” followed by chapter 4 “Data Presentation”. Finally, the results are discussed in chapter 5 “Analysis and Discussion” and conclusions in Chapter 6.

A avaliação da efetividade da política de ressarcimento ao Sistema Único de Saúde

A necessidade de coibir o descontrole do mercado dos planos de saúde tornou-se uma questão importante no cenário nacional, na década de 90. Desta forma, 10 anos após a criação do Sistema Único de Saúde (SUS), em um contexto de pressões e de baixa regulação dos planos de saúde, instituiu-se a Lei no 9.656/1998, uma legislação inédita no Brasil, pois regulou as atividades das operadoras de planos de saúde (OPSs) em nível nacional. Dentre outras questões, a Lei estabeleceu a política de ressarcimento ao SUS, impondo no Artigo no 32 o ressarcimento pelas OPSs das despesas geradas ao SUS quando um beneficiário usa a rede pública para um procedimento coberto pelo seu plano. No entanto, esta política é parte dos conflitos que se situa no limite dos interesses entre o setor privado e público: as OPSs já em 1998 moveram uma ação direta de inconstitucionalidade contra a mesma e têm recorrido frequentemente ao judiciário para não pagarem os valores cobrados pela Agência Nacional de Saúde Suplementar (ANS). Após 12 anos da Lei, ainda não se conhece o seu real impacto. Portanto, o presente trabalho teve como objetivo avaliar a efetividade da política de ressarcimento ao SUS. A metodologia utilizada baseou-se na avaliação de dados produzidos pela ANS e pelo Ministério da Saúde/DATASUS, e das entrevistas realizadas com gerentes da rede pública e privada. Apesar das ações da ANS, os resultados apontaram a reduzida efetividade da política em termos financeiros, jurídicos e sobre o seu público-alvo. Apenas 22% do cobrado às OPSs foi restituído ao Sistema Único de 1999 a 2006, a política é vista como inconstitucional pelo mercado e tem reduzido impacto sobre as OPSs, o SUS e os beneficiários. Questões como os valores da tabela única nacional de equivalência de procedimentos (TUNEP), a inconstitucionalidade do ressarcimento e a opção do beneficiário pelo uso do SUS foram explicitadas pelos gestores de planos de saúde como fatores geradores de resistência das OPSs frente à política. Os dirigentes públicos afirmaram a importância da mesma para tutela de beneficiários e do SUS, como de ter viabilizado a construção do Cadastro de Beneficiários da ANS, porém, reconhecem os seus baixos resultados. Recomenda-se a manutenção do ressarcimento ao Sistema Único como um instrumento para coibir empresas que procuram contornar as exigências legais da Agência Reguladora, a qual atua promovendo a defesa do interesse público na assistência suplementar à saúde. No entanto, a mesma deve sofrer as devidas reformulações e devem ser estabelecidos consensos entre o SUS e o setor suplementar.

Privacidade e inovação na era do Big Data

A coleta e o armazenamento de dados em larga escala, combinados à capacidade de processamento de dados que não necessariamente tenham relação entre si de forma a gerar novos dados e informações, é uma tecnologia amplamente usada na atualidade, conhecida de forma geral como Big Data. Ao mesmo tempo em que possibilita a criação de novos produtos e serviços inovadores, os quais atendem a demandas e solucionam problemas de diversos setores da sociedade, o Big Data levanta uma série de questionamentos relacionados aos direitos à privacidade e à proteção dos dados pessoais. Esse artigo visa proporcionar um debate sobre o alcance da atual proteção jurídica aos direitos à privacidade e aos dados pessoais nesse contexto, e consequentemente fomentar novos estudos sobre a compatibilização dos mesmos com a liberdade de inovação. Para tanto, abordará, em um primeiro momento, pontos positivos e negativos do Big Data, identificando como o mesmo afeta a sociedade e a economia de forma ampla, incluindo, mas não se limitando, a questões de consumo, saúde, organização social, administração governamental, etc. Em seguida, serão identificados os efeitos dessa tecnologia sobre os direitos à privacidade e à proteção dos dados pessoais, tendo em vista que o Big Data gera grandes mudanças no que diz respeito ao armazenamento e tratamento de dados. Por fim, será feito um mapeamento do atual quadro regulatório brasileiro de proteção a tais direitos, observando se o mesmo realmente responde aos desafios atuais de compatibilização entre inovação e privacidade.

Environmental regulation, technology adoption and structural transformation: evidence from Brazilian sugarcane industry

We estimate the effects of the adoption of mechanized agriculture led by a new environmental regulation on structural change of local labor markets within a large emerging country, Brazil. In 2002, the state of S\~{a}o Paulo passed a law outlying the timeline to end sugarcane pre-harvest burning in the state. The environmental law led to the fast adoption of mechanized harvest. We investigate if the labor intensity of sugarcane production decreases; and, if so, if it leads to structural changes in the labor market. We use satellite data containing the type of sugarcane harvesting -- manual or mechanic harvest -- paired with official labor market data.%, also geomorphometric data base for our instrumental variable correction. We find suggestive evidence that mechanization of the field led to an increase in utilization of formal workers and a reduction in formal labor intensity in the sugarcane sector. This is partially compensated by an increase in the share of workers in other agricultural crops and in the construction and services sector. Although we find a reduction in employment in the manufacturing sector, the demand generated by the new agro-industries affected positively the all sectors via an increase in workers' wage.

Reach: is such regulation WTO consistent?

This present study analyses the Regulation on Chemicals of the European Union – so called REACH, and some of its main features. Technical barriers to trade have become the new instrument of distorting international trade benefits and creating protection for domestic industry, on the basis of protection of human health and the environment. It aims at identifying REACH’s most primary and controversial element and its consistency under the World Trade Organization System, in context of the Agreement on Technical Barriers to Trade
