    Sustentabilidade ambiental na indústria petrolífera: uma análise das estratégias de transição energética da petrobras no período 2003-2023
    (Universidade Federal do Espírito Santo, 2025-03-11) Serrão Neto, Walter; Grassi, Robson Antônio; https://orcid.org/0000-0003-3735-3427; http://lattes.cnpq.br/1705867851062589; Sessa, Celso Bissoli; Lino, Leandro de Souza
    The energy transition is a central theme on the global agenda, driven by the need to reduce dependence on fossil fuels, which still account for approximately 82% of the world's energy production. Over the decades, the oil industry has established itself as one of the most influential and profitable sectors, playing a crucial role in the global economy. However, the environmental impacts and climate change associated with the burning of the fossil fuels, the main source of greenhouse gas (GHG) emissions, highlight the urgency of transforming the global energy matrix towards less polluting sources. This process challenges the oil and gas industry, which faces the dilemma of accelerating its energy transition without compromising existing investments in research, development, and innovation (RD&I) in traditional exploration and production areas. In the specific case of Petrobras, from 2003 to 2023, sustainability and energy transition strategies were strongly influenced by the characteristics of the incumbent governments. Governments with a more interventionist approach prioritized long-term investments, including in energy transition, while market-oriented governments focused on short-term financial results, downgrading environmental and energy transition issues to secondary importance. This study analyzes Petrobras’ evolution in this political context, considering the impact of environmental agreements to combat global warming and corporate guidelines on the sustainability of its operations. The methodology combined document analysis of Petrobras’ financial and sustainability reports, studies from industry agencies, climate non-governmental organizations, and comparisons with international majors operating in Brazil. The results show that, although Petrobras has advanced in operational efficiency and decarbonization, particularly with technologies such as carbon capture, utilization, and storage (CCUS), applied mainly due to pre-salt operational needs, the company has moved away from strategic areas in renewable energies such as biofuels, onshore and offshore wind energy, solar energy, and hydrogen. These technologies are the focus of leading global oil companies due to their synergy with existing infrastructures and the sector's accumulated expertise. A comparison with companies such as Shell, BP, Total, and Equinor, which are major players operating in Brazil, reveals that Petrobras lags in the race to diversify the energy matrix, although it surpasses operators like PetroChina in terms of adherence to market best practices. Thus, to maintain its relevance in the medium and long term in an increasingly regulated and competitive market, Petrobras must integrate clean technologies, adopt stricter sustainability standards, and balance economic growth with technological innovation. The pricing of GHG emissions and the pressure for policies aligned with ESG agendas make this balance essential for the company’s future

    A produtividade total dos fatores e o mercado acionário : evidências para o mercado brasileiro
    (Universidade Federal do Espírito Santo, 2025-02-25) Lago, Jardel Nogueira Oliveira; Moreira, Ricardo Ramalhete ; https://orcid.org/0000-0002-1905-4872; http://lattes.cnpq.br/3263921271806291; https://orcid.org/0000-0001-5605-185X; http://lattes.cnpq.br/0969060931987690; Monte, Edson Zambon ; https://orcid.org/0000-0002-6878-5428; http://lattes.cnpq.br/5543595580825181; Santos, Daiane Rodrigues dos ; https://orcid.org/0000-0001-9215-2260; http://lattes.cnpq.br/6580851334706525
    This dissertation analyzes the relationship between Total Factor Productivity (TFP) and the Brazilian stock market, considering different segments represented by the indices IBOV, SMLL, and IDIV. Using an econometric approach with Vector Autoregression (VAR) and Vector Error Correction (VEC) models, the research captures the short- and long-term dynamics between the variables and identifies the impacts of TFP shocks on stock market performance. The results indicate that positive TFP shocks favorably influence stock indices, with heterogeneous responses depending on the characteristics of the sectors represented by each index. Additionally, stock indices have a positive and permanent impact on TFP in the long term, suggesting that the stock market may act as a productivity catalyst

    Impacto do processo educacional da Ufes: uma avaliação do diferencial de salário dos seus egressos no mercado de trabalho formal
    (Universidade Federal do Espírito Santo, 2024-09-20) Pena, Amanda Carla Ramos; Hott, Henrique Augusto Campos Fernandez; Giuberti, Ana Carolina; https://orcid.org/0000-0001-6685-6272; Melo, Ana Paula; Piza, Caio Cícero de Toled
    We examine the short-term impact on earnings in the formal labor market for students of the Federal University of Espírito Santo (UFES). Using a quasi-experimental approach, we identify the causal effects of enrolling at UFES on formal employment and wages. Taking advantage of the characteristics of the university entrance exam, we applied the Fuzzy Regression Discontinuity (RDD) model to estimate these effects. Although the overall results are inconclusive, there are indications of a positive effect on wages for women who opted for the Quota System. Additionally, for women in general, there is a positive effect on the probability of obtaining a degree and the likelihood of employment in the formal market. However, further research with a more extended timeframe and a larger sample will be necessary to reach more robust conclusions.

    Pagamentos por serviços ambientais impactam a cobertura florestal? : uma avaliação do Programa Reflorestar

    Studies on Payment for Environmental Services (PES) programs have expanded, yet a gap remains in the literature regarding their impact evaluation, especially in the Brazilian context. This paper aims to fill this gap by evaluating the Reflorestar program, implemented by the government of the state of Espírito Santo, estimating its impact on forest cover and land use. Using data from the Rural Environmental Registry and satellite imagery, we applied Mahalanobis distance matching and difference-in-differences methods, as well as doubly robust estimators (Sant’Anna and Zhao, 2020) to estimate the average treatment effect on the treated. The results indicate that properties participating in the Reflorestar program experienced a significant percentage increase in areas of vegetation cover categories such as Forest (13.1%) and Early Stage Native Forest (10.1%), and land use categories such as general crops (12.5%), banana plantations (5.2%), and papaya plantations (2.2%). Furthermore, the results pointed to a reduction of approximately 13% in areas allocated to pasture. This study enriches the understanding of PES programs in Brazil, offering a thorough analysis of the impact evaluation of the Reflorestar program, highlighting positive effects in specific land use categories, particularly those aimed at reforestation

    The present dissertation aims to study the financial sustainability of the unemployment insurance program in Brazil based on its ability to adapt to the country's socioeconomic changes between the years 2000 and 2022. To analyze this topic, the theoretical approach of the Post-Keynesian School was chosen. In this way, the historical evolution of the unemployment insurance program in Brazil and its operation from 2000 to 2022 is analyzed. The core of this investigation starts from the increase in insurance expenses, the amount paid with the benefit between 2008 and 2015 increased by around 140%. This led to the investigation of the long-term relationship between revenues from the Workers' Support Fund (FAT), unemployment insurance expenses and macroeconomic variables GDP and the unemployment rate. To this end, the econometric methodology of a vector error correction model (VECM) was used. The results indicated that the variables included in the model play a significant role in explaining variations in FAT revenue in the long term. This empirical evidence strengthens post-Keynesian interpretations about the need for stability in employment policies and the economy as a whole for the sustainability of the social protection system
