    Brazilian states in the context of COVID-19 pandemic : an index proposition using network data envelopment analysis.
    (2021) Mariano, Enzo Barberio; Torres, Bruno G.; Almeida, Mariana Rodrigues de; Ferraz, Diogo; Rebelatto, Daisy Aparecida do Nascimento; Mello, João Carlos Soares de
    This study aims to evaluate comparatively the situation of the federal units and the Brazilian states in relation to the pandemic of new coronaviruses (COVID19) through the technique of Network Data Envelopment Analysis (Network DEA - NDEA). For the development of research, data were collected on the Ministry of Health website, for all regions that register cases of virus cases notified until April 27, 2020. The purpose of the analysis is to assess regional discrepancies in the country. The model consists of the following structure: three inputs (number of doctors, number of respirators and number of clinical beds), an intermediate variable (number of reported cases) and one output (number of deaths). The results indicated that the federative unit with the worst performance overall was Amazonas, while the worst capital was Manaus. With two-dimensional representation, managers can visualize better which locations have the worst performance and assess which locations require more assistance. Depending on the results, managers can develop regional action plans, which can take steps to prevent the collapse of the health system.

    COVID health structure index : the vulnerability of Brazilian microregions.
    (2021) Ferraz, Diogo; Mariano, Enzo Barberio; Manzine, Patricia Regina; Moralles, Herick Fernando; Morceiro, Paulo César; Torres, Bruno Guimarães; Almeida, Mariana Rodrigues de; Mello, João Carlos Soares de; Rebelatto, Daisy Aparecida do Nascimento
    Many developing countries have highly unequal health systems across their regions. The pandemic of COVID-19 brought an additional challenge, as hospital structures equipped with doctors, intensive care units and respirators are not available to a sufcient extent in all regions. Using Data Envelopment Analysis, we create a COVID Index to verify whether the hospital structures in 543 Brazilian microregions are adequate to deal with COVID-19 and to verify whether public policies were implemented in the right direction. The results indicate that hospital structures in the poorest microregions were the most vulnerable, although the peak of COVID-19 occurred in the richest microregions (Sao Paulo). The Southeast states could relocate hospital resources or even patients between their regions. The relocation was not possible in many states in the Northeast, as the health system poorly assisted the interior of these states. These fndings reveal that the heterogeneity of microre- gions’ hospital structures follows the patterns of socioeconomic inequalities. We conclude that it is easier for the wealthier regions to reallocate hospital resources internally than for the poorest regions. By using the COVID Index, policymakers and hospital managers have straightforward information to decide which regions must receive new investments and reallocate underutilized resources.

    Determinants of Absorptive Capacity : a systematic literature review.
    (2021) Silveira, Naijela Janaina Costa; Ferraz, Diogo; Mello, Diego Scarpa de; Silva, Eduardo Polloni; Rebelatto, Daisy Aparecida do Nascimento; Moralles, Herick Fernando
    Purpose – To conduct a literature review on the determinants of Absorptive Capacity (AC), which allows for productivity spillovers from Foreign Direct Investment (FDI) in developed and developing countries. Theoretical framework – This study is based on the literature indicating that before benefiting from spillovers, companies need a certain level of knowledge and expertise. Design/methodology/approach – A Systematic Literature Review (SLR) of empirical studies on AC and productivity spillovers is presented. A total of 60 articles were reviewed. Findings – The SLR revealed that human capital and R&D investments are the most frequently cited determinants of AC. R&D is especially important for developing countries. Research, Practical & Social implications – Public policies targeting R&D development may be a valuable strategy to facilitate productivity spillovers in developing countries. Originality/value – This paper analyzes the determinants of AC while verifying how both developed and developing countries can benefit from FDI, which is of great importance considering the growth of FDI in developing countries.

    Energy efficiency and China's sustainable carbon neutrality target : evidence from novel research methods quantile on quantile regression approach.
    (2022) Bao, Zongke; Ferraz, Diogo; Rebelatto, Daisy Aparecida do Nascimento
    Since the last few decades, scholars and policy-makers have been struggling to find ways to achieve carbon neutrality target or a low carbon economy. To contribute to the existing literature regarding the said issue, this study aims to investigate whether energy efficiency could lead to achieving carbon neutrality target in the case of China. Also, this study analyses the association of economic growth to energy-related greenhouse gas emissions while using quarterly data over the period from 1990Q1 to 2014Q2. Empirical findings of the study suggest the mixed order of integration and Cointegration between economic growth, energy efficiency, and energy-related greenhouse gas emissions. This study employed a Quantile-on-Quantile regression approach to examine the long-run association at various quantiles. The esti- mated results asserted that energy efficiency holds a weaker rela- tionship in the lower and medium quantiles, while relatively higher association to energy-related emission in the upper quan- tiles. On the other hand, economic growth and its squared are found significantly and highly associated with enhancing energy- related emissions in the country. Besides, the frequency domain causality indicates a causal association running from energy effi- ciency and economic growth to energy-related greenhouse gas emissions. This study recommends revised policies for energy effi- ciency and suggests that economic growth could be used as a remedial measure for environmental recovery by enhancing investment in the renewable energy sector, energy efficiency, and structural transformation of the industrial sector.

    Environmental Kuznets curve and the pollution-halo/haven hypotheses : an investigation in Brazilian municipalities.
    (2021) Silva, Eduardo Polloni; Ferraz, Diogo; Camioto, Flávia de Castro; Rebelatto, Daisy Aparecida do Nascimento; Moralles, Herick Fernando
    There is much discussion on the non-linear relationship between economic growth and carbon dioxide (CO2) emissions. Additionally, the effects of Foreign Direct Investment (FDI) on the environment are ambiguous, as both beneficial (i.e., pollution-halo) and harmful (i.e., pollution- haven) effects were found. Therefore, the literature presents no consensus on either of these topics. This is especially problematic for developing regions, as these regions represent growing economies interested in receiving foreign investments, and their CO2 -related research is limited. This study aims to understand the impacts of economic growth and FDI on the CO2 emissions of São Paulo state, Brazil. To perform this study, a unique dataset on regional FDI was built, and 592 municipalities were included. The analyses combine linear and non-linear estimations, and the results suggest a non-linear relationship between Gross Domestic Product (GDP) per capita and CO2 emissions, along with a negative association between FDI and CO2 . Finally, this study discusses possible policy implications and contributes to the international literature.

    Mechanization in sugarcane production and other agricultural activities : an econometric analysis of employment and income.
    (2021) Ferraz, Diogo; Oliveira, Fabíola Cristina Ribeiro de; Rebelatto, Daisy Aparecida do Nascimento; Pyka, Andreas
    Several studies argue that agricultural mechanization has reduced employment and wages. However, there is a lack of studies analyzing employment and income over time, especially comparing the agricultural activities. Our major argument is the structural change in the employment - from un-skilled to skilled workers which has to be understood because of the overall decrease in the number of jobs. This study aims to analyze the labor market evolution in sugarcane farming and other agricultural activities, from 1992 to 2015. Using the National Household Sample Survey (PNAD/IBGE), we compared sugarcane and other Brazilian crops using econometrics techniques. We analyzed the Heckman's procedure and models with fixed effects panel data, controlling the unobservable characteristics of workers. Methodologically, our equations show convergence, since the Heckman procedure and pooled regression present similar estimates. We showed that fixed- effect regression captures the same trends of Ordinary Least Square (OLS) technique, using the Heckman method. Our main findings suggest that the wage of sugarcane workers is higher than wages in other crops, even after we control the observable and regional characteristics. This finding is important because the sugarcane sector has faced criticism regarding the low level of employment and income due to the mechanization process. Finally, we pointed out the decrease in unskilled jobs in sugarcane, which demands for policy intervention to improve the human capital in the sugarcane sector.

    The circular economy, bioeconomy, and green investments : a systematic review of the literature.
    (2022) Berto, Pietro Jacomini; Ferraz, Diogo; Rebelatto, Daisy Aparecida do Nascimento
    Purpose – This study aims to evaluate the theoretical concept of the Bioeconomy and the Circular Economy in association with studies about green finance. Theoretical framework – Several studies pointed out that sustainable investments must replace production processes. This literature provides a favorable environment for new studies on the Circular Economy and Bioeconomy. However, the literature lacks definitions and differentiation between both concepts. Design/methodology/approach – A Systematic Literature Review (SLR) was adequate to systematize the information from 345 articles, 231 relating to the Circular Economy, and 114 articles relating to the Bioeconomy. In addition, the contents of the 24 articles with the highest number of citations was reviewed. Findings – Our analysis revealed that the concepts of the Circular Economy and Bioeconomy could be similar or different. The concepts are similar due to the concern with sustainable economic development. However, the Circular Economy uses concepts that are related to the differentiation of the paradigm from a linear productive system to that of a loop. The Bioeconomy is more concerned with the use of biological resources and biotechnology. A geographic distribution of the studies can also identify the differences as well as the number of publications, citations, and methods used. However, both approaches equally show a scarcity of databases. Originality/value – Our study reveals that the Bioeconomy concept is hardly used in countries with high biodiversity, for example, countries that make up the Amazon region. On the other hand, there was a greater synergy between the Circular Economy approach and production processes in different economic sectors in developing countries.
