A intervenção do estado na economia: um estudo de caso do setor elétrico

Estuda-se a intervenção do Estado na economia através da regulação, tendo como objeto de análise o setor elétrico brasileiro. O presente estudo tem como objetivo verificar de que forma o Estado, desde a promulgação da Constituição de 1988, buscou cumprir os princípios estabelecidos na Ordem Econômica constitucional e exercer a sua função de ente regulador, fiscalizador, planejador e indutor do crescimento econômico, no setor elétrico. Analisa-se a reforma do Estado pensada pelo ex-Ministro Bresser Pereira e a inclusão de empresas do setor elétrico no Plano Nacional de Desestatização. Observa-se que o processo de privatização permanece inacabado nos segmentos da geração e da transmissão. Investiga-se a instituição do MAE e a criação do produtor independente de energia elétrica, no contexto de uma reforma que pretendia encaminhar o setor elétrico para o livre mercado. Estuda-se a crise de racionamento e a mudança de estratégia do Governo, cuja prioridade passou a ser um maior planejamento central que garantisse a segurança energética e a expansão da geração e transmissão. Analisa-se as diferenças entre o ACL e o ACR, bem como a formação do preço da energia elétrica em cada um e conclui-se, por meio da leitura de precedentes do CADE, que trata-se do mesmo mercado relevante na dimensão produto. Investiga-se as mudanças trazidas pela MP-579 e de que forma a intervenção do Estado no setor elétrico aumentou, e os impactos que isso trouxe. Conclui-se que, a partir da edição da MP-579, a intervenção do Estado no setor elétrico aumentou com o objetivo de controlar os preços e garantir a segurança energética, mas que as mudanças regulatórias não foram bem sucedidas em manter e a tarifa da energia paga pelo consumidor final em patamares baixos, tampouco em garantir a oferta de energia elétrica suficiente para cobrir a demanda das distribuidoras.

Time beyond clock: time use-surveys revisited

Time use surveys -despite having represented a turning point in the study of inequalities between women and men- continue hiding care times and subtracting relevance to the qualitative dimensions of time. This due both, to the ideological conception that lies behind this type of studies that consider more relevant market process as to surveys methodology. This article analyzes the theoretical model that lies behind time use surveys and, consequently, the study of the conceptual aspects, the methodology and the potential of these surveys as an analytical instrument. The aim is to unraveling the limitations presented by the surveys to take in account the subjective dimensions of time related to the wellbeing of  people.

Are all new market entry strategic dimensions equally relevant?: insights from some chilean experts?

This thesis looks into the strategic dimensions that Multi-National Companies (MNC) consider when they start the operation in a new country in Latin America and if all have the same weight or relevance when doing the strategic decisions as a guide to land onto a new country. Understanding the weight that MNCs gives to them can prompt to understand the reasons behind the success stories, the struggles - and even failures - that some companies had in the aforementioned region. The approach was via an initial analysis of the scholar bibliography in order to define three main dimensions in the models or frameworks that deal with the strategy used to land. After this, and through interviews, was found out how relevant are each of them for their companies, how they weight them and if there were other dimensions considered. The question that this thesis contributes to understand is if all new market strategic dimensions are equally relevant for a MNC when arriving to Latin America. The results show a predominance of the cultural aspect and in second place, the considered entry strategy (alliances, speed, size, etc.).

Notes on market failure and the Paretian (Kaldor-Hicks) relevance and irrelevance of unfavourable externalities

The following are notes that have been distributed by me over the last few years to students in Environmental Economics at The University of Queensland. They give particular attention to whether externalities are Pareto or Kaldor-Hicks relevant from a policy point of view. Externalities are Kaldor-Hicks or Pareto irrelevant if no change is possible for which gainers could compensate losers. Both absolute and marginal externalities may be Kaldor-Hicks relevant. Infra-marginal negative externalities are often, but not always, Kaldor-Hicks irrelevant. There are at least two cases where such externalities can be relevant. First, the absolute impact of the negative externality may be so great that the source of the externality should be eliminated. Secondly, if the externality arises from production, its nature may depend on the type of production technique adopted. Although for the technique adopted, an infra-marginal negative externality occurs. That is Paretian irrelevant given that choice of this technique is the only available possibility, alternative techniques may actually be available in practice. Some of these may generate even smaller total external effects and be socially preferable. Both cases are outlined and illustrated in these notes. The analysis reveals the dangers of relying on marginalism for deciding on environmental policy. Total (external) effects are often of great social and economic importance and appropriate social choices cannot be made on the basis of marginalism alone.

Comparing exchange market pressure in West and Southern African countries

We compare the performance of Cape Verde and Mozambique concerning financial credibility as measured by Exchange Market Pressure, an institutional feature that has often been overlooked in the literature as a relevant institution for economies. Drawing on previous research by Macedo et al. (2009), we expand their analysis and, using several definitions of “financial credibility”, all related to different angles on Exchange Market Pressure indices, we conclude that - against reasonable benchmarks in their respective regions - financial credibility has been very good for Cape Verde and fairly good for Mozambique.

A wave of change: Labor market and social security impacts of the EU refugee inflow

The recent massive inflow of refugees to the European Union (EU) raises a number of unanswered questions on the economic impact of this phenomenon. To examine these questions, we constructed an overlapping-generations model that describes the evolution of the skill premium and of the welfare benefit level in relevant European countries, in the aftermath of an inflow of asylum-seekers. In our simulation, relative wages of skilled workers increase between 8% and 11% in the period of the inflow; their subsequent time path is dependent on the initial skill premium. The entry of migrants creates a fiscal surplus of about 8%, which can finance higher welfare benefits in the subsequent periods. These effects are weaker in a scenario where refugees do not fully integrate into the labor market.

MarketOpolis: A market simulation based on investors decisions

This study aims to replicate Apple’s stock market movement by modeling major investment profiles and investors. The present model recreates a live exchange to forecast any predictability in stock price variation, knowing how investors act when it concerns investment decisions. This methodology is particularly relevant if, just by observing historical prices and knowing the tendencies in other players’ behavior, risk-adjusted profits can be made. Empirical research made in the academia shows that abnormal returns are hardly consistent without a clear idea of who is in the market in a given moment and the correspondent market shares. Therefore, even when knowing investors’ individual investment profiles, it is not clear how they affect aggregate markets.

Anatomy of the portuguese stock market risk and return in the 1977-2012 period

This paper analyses the Portuguese stock market since it reopened in 1977, with a special focus on the evolution of the statistic and stochastic characteristics of the market return throughout this 36 year period. The market return for the period of time between 1977 and 2012 (September 28th) is estimated and then compared with the return that would have been achieved with Government bonds and treasury bills, which allows us to confirm that the hierarchy of return / risk across the different financial instruments is verified. The market risk premium for this 36 year period is also estimated and a comparison with other markets is performed, suggesting that the Portuguese market’s risk has not been compensated by an adequate return. The study also examines the evolution of the Portuguese market’s volatility in the 1977-2012 period and compares it with other markets, showing the existence of extremely high peaks during the first 11 years, but indicating a downwards trend throughout the whole period under analysis. Finally, the correlation between market returns for Portugal and for other countries and the degree of integration are estimated and their evolution throughout time is assessed, leading to the conclusion that the performance of the Portuguese stock market has become increasingly correlated with major European markets – correlation with some markets close to 0.70 from 2000 onwards-, but that country-specific risk factors are still relevant.

The Part-time pay penalty in a segmented labor market

This paper is the first to examine the implications of switching to PT work for women's subsequent earnings trajectories, distinguishing by their type of contract: permanent or fixedterm. Using a rich longitudinal Spanish data set from Social Security records of over 76,000 prime-aged women strongly attached to the Spanish labor market, we find that PT work aggravates the segmentation of the labor market insofar there is a PT pay penalty and this penalty is larger and more persistent in the case of women with fixed-term contracts. The paper discusses problems arising in empirical estimation (including a problem not discussed in the literature up to now: the differential measurement error of the LHS variable by PT status), and how to address them. It concludes with policy implications relevant for Continental Europe and its dual structure of employment protection.

Report to the Minister for Health and Children on Risk Equalisation in the Irish Private Health Insurance Market

Provision for risk equalisation was first made in the Health Insurance Act, 1994, section 12 of which empowered the Minister to prescribe a scheme for risk equalisation. A Risk Equalsiation Scheme was introduced in 2003. In December 2005, the Minister decided, on the Authorityâ?Ts recommendation, which referred to risks now materialising, to commence risk equalisation payments under the Scheme as from 1 January 2006, but in the event the relevant legislation was overturned by the Courts in 2008.

Review of Measures to Reduce Costs in the Private Health Insurance Market 2014

5.11.2014 This report was prepared independently by Mr McLoughlin with the support of the health insurers, and the Health Insurance Authority, for consideration by the Minister for Health and the insurers.  All parties were very conscious of the importance of respecting competition law when dealing with issues such as prices and costs. The work of the Group has been conducted in two phases, with the first phase report published on 26 December 2013. The Phase 1 report sets out the context, establishment, membership and terms of reference for both phases of the Groups work.  The report also outlines the legislative provisions for private health insurance in Ireland, the objectives of both phases of the review and the approach and methodology followed. Phase 2 of the process focused on the compilation and analysis by the Health Insurance Authority (HIA) of claims data to assess the cost drivers for health insurance, the effects of medical technology and innovations on costs, and claims processing issues.The report and submissions from relevant stakeholders which were examined and considered under the Phase 2 Review can be downloaded below.
