Análise das transações na cadeia produtiva do leite em Goiás sob a ótica da Nova Economia Institucional
(Universidade Federal de Goiás, 2023-04-11) Rosa, Glaicon Mendes; Cunha, Cleyzer Adrian da; http://lattes.cnpq.br/8809108474226649; Cunha, Cleyzer Adrian da; http://lattes.cnpq.br/8809108474226649; Wander, Alcido Elenor; http://lattes.cnpq.br/8250997651281553; Silva, Adriana Ferreira; http://lattes.cnpq.br/9139904100110345
This dissertation aimed to analyze the factors that influence the transactions in the milk production chain in Goiás. To achieve this goal, the qualitative field research was conducted with the agents of the production chain, allowing an analysis of the transactional attributes present in the relations between industries, producers and other agents. The research uses the theory of the New Institutional Economics (NEI) at its analytical level, the Economics of Transaction Costs (ECT), to analyze the transactions and reach the current governance structure. The results of the research show that the form of coordination of institutional relations in the milk production chain in Goiás is consolidated from institutionalized practices, with certain industries, producers/suppliers, customers practicing the use of production/supply contracts in specific cases, even with several market relations and contracts not formalized. However, the contracts between the parties are intrinsically incomplete, which does not make it economically feasible to specify clauses for all possible contingencies due to the limited rationality and opportunism existing in the relations. In addition, price mechanisms have flaws in their structures in the production chain, which changes the way agents behave and, consequently, their actions in the economic field, according to the configuration of hybrid structure transactions. The importance of this research lies in the understanding of the factors that influence the transactions in the which may contribute to the development of public policies and business strategies aimed at promoting sustainable growth of dairy cattle in the region.
Distribuição espacial da insegurança alimentar e nutricional e seus determinantes nos municípios do Estado de Goiás
(Universidade Federal de Goiás, 2025-05-29) Guimarães, Paulo José Paiva; Cardoso, Larissa Barbosa; http://lattes.cnpq.br/8423459003676034; Cardoso, Larissa Barbosa; Santiago, Flaviane Souza; Silva, Adriana Ferreira
The objective of this study is to analyze the spatial distribution and the determinants of food and nutritional insecurity (FNI) in the municipalities of the state of Goiás. FNI is defined as the lack of necessary conditions for a healthy and sufficient diet to maintain the individual’s long-term well-being, considering their biological, social, psychological, and economic needs, among others. It is a multifactorial phenomenon involving factors related to availability, access, consumption, and utilization. Existing analyses reveal spatial patterns of FNI with a tendency for spatial clustering. However, this aspect has still been little explored in the analysis of FNI determinants. To investigate these issues, the study focuses on the State of Goiás, where largescale food production coexists with food insecurity. To achieve the proposed objective, FNI in the municipalities of Goiás was measured by calculating a food and nutritional security index, generated through a scoring protocol of 25 indicators. Based on this index, an exploratory spatial data analysis was conducted to identify spatial patterns in FNI prevalence. Additionally, a SAR-probit model was estimated to analyze the determinants of FNI, incorporating spatial dependence between municipalities. Results show that in Goiás, only 5.28% of municipalities are food and nutritional secure (FS), while the remaining 94.31% were classified as FNI. There is a predominance of mild FNI, with a higher prevalence of moderate and severe FNI in municipalities of the Northern Goiás mesoregion. The findings indicate that the Gini index of household income and unemployment are positively associated with the likelihood of FNI. Household per capita income, access to treated water, coverage of the Family Health Strategy (FHS) program, and exclusive breastfeeding up to four months are negatively associated. The exploratory data analysis reveals positive spatial autocorrelation, meaning neighboring municipalities tend to show similar FNS/FNI conditions. The SAR-probit model reinforces the existence of spatial dependence in the prevalence of FNI among municipalities, indicating similarity-based clustering. Exclusive breastfeeding up to four months, ESF coverage, and access to treated water were identified as the main determinants of FNI probability in Goiás, after spatial effects were controlled. Thus, these variables are the most strategic for locally focused FS intervention programs.
As multidimensões da Pobreza no estado do Piauí: uma análise a partir do método Alkire - Foster
(Universidade Federal de Goiás, 2024-02-16) Monte, Marcus Felipe Pessoa do; Silva, Adriana Ferreira; http://lattes.cnpq.br/9139904100110345; Silva, Adriana Ferreira; Cardoso, Larissa Barbosa; Miranda, Sílvia Helena Galvão de
The objective of the present study is to examine the profile of multidimensional poverty in the state of Piaui, based on the estimation of a multidimensional poverty index (IPM), regarding dimensions and indicators, based on the Alkire - Foster (AF) method and the Global Multidimensional Poverty Index (MPI). The contribution of the research focuses on the detailed analysis of multidimensional poverty in the state so that the results obtained can be used as an instrument for monitoring and combating poverty. To construct the index, information from the IBGE National Household Sample Survey (PNAD) was used, referring to the year 2015. The results indicate that 11.42% of households in the state of Piaui are multidimensionally poor, with 1.83% in a situation of extreme poverty. These numbers indicate a more critical scenario about Brazil and the Northeast region, where poverty records percentages of 4.1% and 8.15%, respectively, with extreme poverty being 0.5% and 1.19% in the same order. The intensity of poverty in Piaui was 43.38%, a similar proportion to the Northeast and Brazil. As for the subgroups analyzed, 27.73% of Piaui households located in rural areas are multidimensionally poor, compared to 3.45% located in urban areas, with their deprivation intensities being 44.8% and 37.81%, respectively; no distinctions between households headed by male and female individuals about the contribution of the indicators; In terms of the age group of household members, there is a higher incidence of poverty in households that have individuals aged 60 or over (18.93%) and a substantially higher value of the (IPM) for households whose head has a informal occupation (0.0754) compared to formal occupation (0.0096). It is understood that such results, by helping to understand the specific needs of the poor population, can contribute to the development of assertive public policies, to reduce poverty and promote more equitable development in the State.
Nexus água-energia-alimento no Brasil: Uma análise quantitativa dos trade-offs e sinergias
(Universidade Federal de Goiás, 2025-02-25) Vieira, Heris Coutinho; Silva, Adriana Ferreira; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4702811Y6; Silva, Adriana Ferreira; Cunha, Cleyzer Adrian da; Schneider, Sergio
This study examines the Water-Energy-Food Nexus (FEW Nexus) in Brazil, focusing on the increasing demand for natural resources and the interactions between water, energy, and food sectors. Specifically, the research aims to analyze the relationships among these sectors by identifying synergies and trade-offs between 42 national indicators. Using Spearman's correlation coefficient, the study explores these interactions to promote integrated and sustainable policies. The results reveal complex dynamics, with a predominance of synergies in the energy (76,36%) and food (59,46%) sectors, while the water sector showed a more balanced distribution of synergies (52,54%) and trade-offs (40,68%). In the water sector, a positive correlation was observed between treated water volume and the area of lakes and rivers, but challenges related to water use efficiency and consumption in irrigation and industry were also identified. In the energy sector, renewable sources such as solar and wind energy proved essential for reducing CO2 emissions and improving energy efficiency, although the reliance on fossil fuels remains a significant challenge. In the food sector, agricultural production correlated positively with efficient water and energy use, but trade-offs were observed concerning child malnutrition and obesity, indicating that increased production does not always ensure food security for all. Interactions between sectors revealed that renewable energy generation can contribute to sustainable water management, while dependence on fossil fuels negatively impacts food security. The study concludes that the FEW Nexus approach is crucial for designing public policies that enhance synergies and mitigate trade-offs, aiming to achieve water, energy, and food security in Brazil. Despite limitations related to data availability and the complexity of interactions, the analysis provides valuable insights for building more sustainable and resilient agri-food systems.
BNDES Exim e o financiamento às exportações: impactos no emprego das firmas e salário dos empregados
(Universidade Federal de Goiás, 2025-02-28) Deus, Guilherme Brito Brandão Ferreira de; Colombo, Daniel Gama e; http://lattes.cnpq.br/3197181545823142; Colombo, Daniel Gama e; Nogueira, Mauro Oddo; Monsueto, Sandro Eduardo
BNDES Exim is an export promotion policy of the Brazilian development bank (BNDES) which aims to boost Brazilian firms’ access to foreign markets. This study presents the first evaluation of the BNDES Exim’s impacts on the employment level of beneficiary firms and on workers’ hourly wages. Accordingly, this work employs two original databases, which were built using three sources: the list of BNDES Exim beneficiaries, the Secretariat of Foreign Commerce (SECEX) list of exporters, and the Annual Report of Social Information (RAIS) from the Brazilian Ministry of Labor and Employment (MTE). This study consists of two autonomous papers in accordance with the variables analyzed. The Brazilian literature on BNDES Exim has found that it increases the export value of its beneficiaries. However, there is a time gap in the literature, since the last study that used microdata was from 2014. Moreover, the literature has not analyzed the employment level and wages yet. This study aims to fill these gaps and expects to further the literature by evaluating if there are any impacts on employment-related variables. These impacts are evaluated according to the learning-by-exporting hypothesis. The results show no evidence of increase in employment level due to a firm receiving funding from the program. Furthermore, the findings suggest that workers from large firms experience a reduction of 8,9% on their wages. However, workers from micro, small and medium-sized firms experience an increase of around 2% on their wages. The findings point to a joint conclusion about the policy: it should be redesigned to focus micro, small and medium-sized firms.
Deu match: o encontro entre formação e ocupação garante melhores salários?
(Universidade Federal de Goiás, 2024-09-17) Oliveira, Alícia Araújo Amaral de; Monsueto, Sandro Eduardo; http://lattes.cnpq.br/5484881117429853; Monsueto, Sandro Eduardo; Monteiro, Waleska de Fátima; Antigo, Mariangela Furlan
The aim of this dissertation is to investigate whether finding a job that is compatible with academic training leads to better salaries, based on an indicator that captures how close the graduate is to their expected occupation. To do this, an academic database is combined with information from the Brazilian formal labor market and, unlike previous literature, this analysis is enhanced by using the median of the grades obtained during graduation as the main instrument for controlling individual aptitudes. Through the estimation of quantile regression models with instrumental variables, segmented for men and women, the results show that the greater the combination of the stock of productive factors assimilated during graduation with the activities required by the position held in the market, the higher the salary earned by the worker. The results also document a small impact of proximity on income for male workers and non-significant impacts at the ends of the quantiles. The opposite scenario is observed among women, and the match proves to be more important for those who are concentrated at the bottom of the income distribution. The occupational match is expected to act as a reducer of the wage inequalities observed between male and female workers.
Mensuração de poder de mercado de bancos sob uma estrutura multiprodutos
(Universidade Federal de Goiás, 2024-04-18) Oliveira, Carolina Bittencourt Amui de; Scalco, Paulo Roberto; http://lattes.cnpq.br/4259596733099005; Scalco, Paulo Roberto; Profeta, Graciela Aparecida; Pinha, Lucas Campio; Cunha, Cleyzer Adrian da
We apply the stochastic frontier approach to estimate market-power of Brazilian banks under a multiproduct structure, due to presents flexibility in relation to the required data, in addition to not requiring firms to present income scaling constants. The average markup practiced by Financial Institutions in Credit Operations reduced throughout the period and is greatly impacted by the Inefficiency of Institutions. It was not possible determine a relationship between Credit Risk and the markup applied. Bacen’s participation in the search for greater transparency and competitiveness in the banking sector in the country, the reduction in HHI in the sample period coincides with the efforts of the Bacen to increase competitiveness in the sector. Despite the markup reduction trend observed, Private Banks maintained and Public Banks increased market power. It was found that larger banks and multiproducts have less market power when compared to singular cooperatives and specialized banks. Some Institutions reported losses in credit operations at the same time as obtained net profit with Revenues from other products, which corroborates the argument of the presence of cross subsidies between products. Another important result is that Financial Institutions do not operate in a competitive market, and on average, the markup results in an increase in Bank Profit compared to the that would be expected in Perfect Competitive Markets
O efeito da feminização ocupacional sobre os diferenciais de rendimentos: um estudo longitudinal na região Centro-Oeste
(Universidade Federal de Goiás, 2023-09-29) Sardinha, Tales Ferraz; Meireles, Débora Chaves; http://lattes.cnpq.br/3776796942428947; Meireles, Débora Chaves; Monsueto, Sandro Eduardo; Proque, Andressa Lemes
In recent decades, the increasing participation of women in the labor market has reflected in typically feminine occupations filled mostly by women. This phenomenon was called occupational feminization. The present study seeks to analyze the influence of occupational feminization on the income of men and women in the Midwest region of Brazil, in the period from 2017 to 2022. For this purpose, longitudinal data from the PNAD Continua was used as a empirical strategy, the Ordinary Least Squares (OLS), Fixed Effects and Logit models with fixed effects. The results showed that there was a penalty in the income of men and women who were allocated to female occupations. Furthermore, it was evidenced that human capital characteristics and the presence of children do not influence income penalties, thus strengthening the Queuing and Devaluation Theories, in which the primary argument is that prejudices rooted in society are determining factors for lower incomes in female occupations.
Análise do mismatch na inserção dos egressos do ensino superior no mercado de trabalho
(Universidade Federal de Goiás, 2023-05-04) Vieira, Pedro Henrique Mendes Rodrigues; Monsueto, Sandro Eduardo; http://lattes.cnpq.br/5484881117429853; Monsueto, Sandro Eduardo; Meireles, Debora Chaves; Simão, Rosycler Cristina Santos
This work aims to analyze the occurrence of mismatch in the national formal labor market through data from a Federal University. In this sense, an attempt is made to find the incidence and probability of graduates have incompatibility between their area of training and occupation and also being considered overeducated, working in occupations with less requirement for years of study. Likewise, it analyzes whether there are differences in the type of absorption in the labor market for graduates from courses considered “elite”, thus testing the hypothesis that graduates from this group are less prone to misfits. The sample comprises graduates from 80 courses at the Federal University of Goiás graduated between 2005 and 2020 and employed in the formal job market. Using a Probit model, the probabilities of the graduates being in one of the mismatch were estimated. The results show that black graduates, from public schools, who work outside Goiânia, work under the CLT regime, are in the public sector, studied applied social sciences and agricultural sciences, were hired before or during the student period and those who attended courses non-elite are more likely to be overeducated. In the mismatch between education and occupation, the greatest probability is found in male graduates, black, coming from private schools, under CLT regime, working in the public sector, graduated in an applied social sciences course, who are in a situation of overeducation, who got a job before or during graduation and who belong to the elite group. With this, it is observed that the hypothesis of lower occurrence of mismatch for individuals coming from elite courses, happens only in the case of overeducation.
Desempenho da produtividade total dos fatores (PTF), na agropecuária das mesorregiões de Goiás entre 1970 e 2017
(Universidade Federal de Goiás, 2023-05-15) Mello Júnior, Fernando Corrêa de; Silva Neto, Waldemiro Alcântara da; http://lattes.cnpq.br/0903453737945294; Silva Neto, Waldemiro Alcântara da; Silva, Adriana Ferreira; Queiroz, Antônio Marcos de
During the 1970s, the process known as agricultural modernization began in the state of Goiás, a little later than in the rest of Brazil, which started in the 1950s. Enabled mainly by public policies promoting regional development and abundant financing, the cerrado region of Goiás saw the introduction of new techniques capable of boosting productivity in the sector, as well as machinery, equipment, and inputs. This work contributes in two aspects i) to the literature, by providing a study of a geographical and regional scope that has not yet been explored; ii) it fills a gap in the detailed analysis of the state of Goiás, which is the fifth largest agricultural producer in the country in terms of Gross Value of Agricultural Production (VBP) in 2022. For the parties involved, it provides analytical evidence of the homogeneity or heterogeneity of the state's productivity, shedding light on state public policies and market decisions made by the productive agents. Given this scenario and the importance of agriculture for Goiás, the objective of this work is to analyze and compare the performance of agricultural Total Factor Productivity (TFP) in Goiás and its different Mesoregions. TFP was chosen as a proxy for productivity. The methodology used focused on analyzing TFP between 1970 and 2017, and its inputs and output indices calculated using the Törnqvist index (1936). The results showed that, starting from 1970, agricultural productivity in the Southern Mesoregion grew at a higher rate than that observed in the state of Goiás and the adjacent mesoregions, with the Capital index experiencing higher growth compared to Labor and Land indices from the same decade, indicating a shift towards largescale production in the regional agriculture, increasing labor and land productivity. The Eastern Mesoregion had the second highest annual growth rate of TFP during the study period, with a 0.13 percentage point difference from the leader. The performance of the Eastern Mesoregion was linked to the increase in the output index in the last two censuses, facilitated by irrigated crops using central pivots. The North and Northwest regions followed trajectories where livestock products had smaller increases in the output index compared to agricultural products, from 1970 to 2017, representing the main contributions to the agricultural value. On the other hand, the Central Mesoregion diverged from the state average of agricultural TFP, as land use for agricultural activities and labor experienced declines starting from 1985, resulting in the lowest average TFP growth during the analyzed period.
Análise bibliométrica da produção científica sobre bioeconomia no Brasil: uma visão panorâmica
(Universidade Federal de Goiás, 2023-05-25) Silva, Guidborgongne Carneiro Nunes da; Silva, Adriana Ferreira; http://lattes.cnpq.br/0903453737945294; Silva, Adriana Ferreira; Barbosa, Cleidinaldo de Jesus; Silva Neto, Waldemiro Alcântara da
Academic works that address the concept of Bioeconomy, as well as the concepts that involve this production model, have been developed in interdisciplinary areas such as energy security, renewable industry and agroecology. Therefore, the characterization of Bioeconomy is still seen as a concept under construction, whose definition and applicability have been presented from different and often divergent approaches. In this context, the main objective of this study is to analyze, through a systematic review and bibliometric analysis of the literature, the scientific production of Brazilian researchers on the subject, between the years 2015 and 2022, in order to assess how the concept of Bioeconomy has been employed. In general, the analyzes of the studies pointed to divergences in the authors' approaches, but convergence regarding the need to integrate different fields of knowledge, with emphasis on areas related to biotechnology, bioinputs and bioecology to enhance an economic model with biological inputs and that preserves the biodiversity. Furthermore, the authors agree that Bioeconomy is a field of knowledge that has provided advances in socio-environmental sustainability actions in a systemic and integrated way among different agents. This research contributes to measure the level of participation of Brazilian researchers in the construction of the concept of bioeconomy
Sustentabilidade da avicultura de corte no estado de Goiás: uma análise sob a ótica da nova economia institucional
(Universidade Federal de Goiás, 2023-04-11) Santos, Willams Douglas dos; Silva, Adriana Ferreira; http://lattes.cnpq.br/9139904100110345; Silva, Adriana Ferreira; Wander, Alcido Elenor; Cunha, Cleyzer Adrian da
The production of chicken meat increased significantly over the past decades, influenced by technical gains in production, slaughter and processing along the poultry chain. In the Brazilian State of Goiás, specifically, production increased expressively too, favored by a highly technological agricultural-industrial system, the significant local supply of grains and the presence of economies of scale. It is in this context that the present study is developed, seeking to understand the sustainability actions carried out in the productive chain of poultry in the State of Goiás. For this, the theoretical assumptions and parameters of the New Institutional Economics were used as a methodological reference, in parallel with the categories of the SWOT Matrix. The data used involved the survey of secondary data from the four main agribusinesses in the State of Goiás. The importance of this research is justified by its contribution to the understanding of the current scenario of chicken meat production, as well as for the understanding of the strategies that are reflected in better sustainable practices in the chain. The results allowed us to conclude that this scenario has led to an increase in the supply of chicken meat, however, causing negative consequences to the environment. To circumvent such effects, the agribusinesses have sought to perform some actions, such as water treatment to return to rivers and springs, renewable energy practices, alternatives that minimize the use of natural resources and reduce the environmental impacts generated by the production of chicken meat.
Negociações coletivas e indústria 4.0 na EU-15: uma análise de modelos condicionais mistos
(Universidade Federal de Goiás, 2023-01-24) Dutra, Matheus Henrique de Araújo; Monsueto, Sandro Eduardo; http://lattes.cnpq.br/5484881117429853; Monsueto, Sandro Eduardo; Bichara, Julimar da Silva; Silva Neto, Waldemiro Alcântara da
Industry 4.0, understood as an innovation process based on cyber-physical systems and the "Internet of Things", is raising the interest of the scientific community for its disruptive potential and its economic and world of work impacts. Thereof, this dissertation aims to analyze the relationship between collective agreements and Industry 4.0 companies in 15 countries of the European Union, based on the level at which they occur and the different industrial relations of different groups of countries, using the concept of Varieties of Capitalism as a theoretical basis. Thus, biprobit-type models are estimated to verify the probability that a bussiness company uses or introduces technologies related to Industry 4.0, based on the level at which such negotiations are presented in a set of explanatory variables from a sample of the European Company Survey. Given the possible presence of unobserved endogeneity and heterogeneity problems, the models are estimated using the estimator of Deb and Trivedi (2006b). The results indicate a positive and significant relationship between the presence of collective agreements, especially that occurring at higher levels, and the probability that the company introduces or already uses I.4.0 technologies. It is also found that collective agreements has a non-linear effect on innovation, and this impact is more relevant in companies with a lower tendency to innovate, belonging to liberal market economies.
Trajetórias da bovinocultura de corte no Brasil e no estado de Goiás: perspectivas para uma transição sustentável
(Universidade Federal de Goiás, 2023-01-18) Gomes, Raquel Oliveira; Silva Neto, Waldemiro Alcântara da; http://lattes.cnpq.br/0903453737945294; Silva Neto, Waldemiro Alcântara da; Silva, Adriana Ferreira; Santos, Ricardo Bruno Nascimento dos
The dissertation is presented in the format of two articles. The first article sought to understand the elements linked to the economic and environmental issue in relation to the characteristics of beef cattle in Brazil and in the state of Goiás, investigating the advances in the main areas highlighted by the literature on the subject, mainly in the issue of animal food quality and in the implementation of integrated systems. The results show that for advances to be achieved in the environmental area, it is necessary that the alternatives presented to the producers consider their economic attractiveness and the operational capacity of their implementation. The second article sought to investigate the effects of demand and supply shocks on the trajectories of beef cattle in Brazil and the state of Goiás, taking into account the environmental aspect. Theoretically, we sought to include greenhouse gas emissions in the econometric modeling of a structural VAR, building on the traditional models initiated by Blanchard and Quah (1989) for Brazilian beef cattle. In the first article, it was possible to identify a set of advances in supplementation and confinement practices that have the potential to reduce greenhouse gases produced by beef cattle. However, the adoption of integrated systems by producers has not yet been shown to be a chosen alternative. In the second article, it was mainly observed that there is a need for planning the growth of the herds at a national level and in the state of Goiás, so that the increase in production in the coming years takes place with productivity gains and a reduction of the environmental impacts of the sector. In general, the components of GHG emissions, which also represent the sector's technological standard, and animal stock had the greatest long-term impacts on the other variables in the sector, reinforcing the need to combine good production practices to increase productivity and reduce the sector's impacts on the environment.
Inferência estatística via bootstrap no modelo de regressão gama unitária
(Universidade Federal de Goiás, 2022-09-16) Barroso, Ihuri Nunes; Silva, Tatiane Ferreira do Nascimento Melo da; http://lattes.cnpq.br/2901210654266903; Silva, Tatiane Ferreira do Nascimento Melo da; Milani, Eder Angelo; Monsueto, Sandro Eduardo
In Economics, there are many situations involving data restricted to the range (0;1), that is, data of rates and proportions, and there are models that are better suited to this situation, such as the Unit Gamma regression model . However, when the sample size is small, or even moderate, the Statistical Inference of these models is compromised. Estimators, in general, tend to become more biased and test statistics lead to less accurate tests. Thus, it is necessary to use tools that are able to correct the bias of estimators and test statistics, such as the method of bootstrap. In this work, we propose Monte Carlo simulations, via bootstrap, which solve the aforementioned problems. In addition, we study socioeconomic variables that impact energy generation through photovoltaic systems, using the Unit Gamma regression model and Statistical Inference via it bootstrap
Programa Nacional do Livro e do Material Didático (PNLD): análise de impacto no período de 2013 – 2020
(Universidade Federal de Goiás, 2022-08-24) Gomes, Patrícia Ribeiro Silva; Monteiro, Waleska de Fátima; http://lattes.cnpq.br/6277244705149516; Monteiro, Waleska de Fátima; Monsueto, Sandro Eduardo; Oliveira, Héder Carlos de
Impact evaluations are an important instrument for verifying the efficiency and effectiveness of public policies, as well as serving as a measure to verify the correct expenditure of public resources. Given the above, as well as the lack of impact evaluation of the Programa Nacional do Livro e do Material Didático (PNLD), this research aims to promote an unprecedented impact evaluation of the mentioned program, measuring the impact of the PNLD on the dropout rate in Brazil. For this, the Propensity Score Matching was the method used, estimating the average effect of the treatment in the treated - ATT. According to the results obtained, it is possible to observe that the program has the expected effect of reducing the dropout rate in schools that chose to participate in the PNLD, as well as it was also identified that other variables, such as the presence of computer lab and library in the school, when associated with the PNLD, contribute to the reduction in the dropout rate.
Exportações brasileiras de carne suína para os principais destinos: uma análise de persistência aos choques
(Universidade Federal de Goiás, 2022-08-19) Xavier, Bruna de Souza; Silva Neto, Waldemiro Alcântara da; http://lattes.cnpq.br/0903453737945294; Silva Neto, Waldemiro Alcântara da; Silva, Renilson Rodrigues da; Silva, Adriana Ferreira
Brazil is the emerging country that most exports pork today. However, it has not advanced in terms of production and exports, occupying, since 2012, the 4th place in the list of the largest producers and exporters of the protein in the world. The main objective of this work is to analyze Brazilian pork exports to the main destinations (China, Russia, Hong Kong, Singapore, Vietnam, Japan and Angola) through an analysis of persistence of shocks between the years 2000 and 2022. The specific objectives are to identify the behavior of each of these series, confirm whether or not they have long memory and verify if the presence of a structural break in the data changes the results of the series. The methodology is based on the long-range dependence test by Lo et al. (1991), and as a way of comparison, other tests were performed, among them are the Classical R/S statistic developed by Hurst (1951); estimation of the fractional integration parameter by spectral regression, or log-perio-dogram, by Geweke and Porter-Hudak (1983); the semiparametric log-periodogram estimator, by Robinson (1995). The results showed that the series exhibit a long memory property and that, in the face of an exogenous shock, Brazilian pork is considered a product with a strong presence in the international market, although subject to export volatility and low diversification of buyers, in addi-tion to political and sanitary interferences. Therefore, the hypothesis confirms the existence of per-sistence of shocks considering that after an exogenous shock it is possible to infer that both the volumes exported and the amounts paid for pork by the selected destinations tend to return to the pattern prior to the event. In this way, the present work differs from the previous literature by analy-zing the behavior of the Brazilian pork export series.
Exportações brasileiras de soja para os principais destinos: uma análise de persistência à choques
(Universidade Federal de Goiás, 2022-05-30) Lima, Juan Lucas Alves de; Silva Neto, Waldemiro Alcântara da; http://lattes.cnpq.br/0903453737945294; Silva Neto, Waldemiro Alcântara da; Mansueto, Sandro Eduardo; Silva, Renilson Rodrigues da
Agribusiness is one of the most important sectors in Brazil. Almost a third of the Gross Domestic Product comes from the segment. In 2020, the participation of agribusiness corresponded to about 27% of the National GDP. Currently, soy is the main Brazilian agribusiness product, which is why the country stands out for being a leader in world production and export. This form of production is present in the five corners of Brazil, in nineteen states and the Federal District. In addition to strong production, Brazilian soy is present in a huge range of destinations, reaching 116 countries that buy Brazilian soy. Given the significant importance that soybeans have for Brazil, and for one of the main players in the global scenario, the objective of this study is to analyze whether the series of Brazilian exports to the main destinations have a long memory, that is, if there is persistence to shocks exogenous. The method used to identify the presence of long memory of the export series is the calculation of the Hurst exponent, H, and structural break tests. The exponent is found by calculating the R/S statistic and the DFA method, and the LM structural break test. The results showed that the Brazilian soybean export market is consolidated and that the shocks do not affect exports in a persistent and permanent way.
Subsídio de bolsas tem efeito na evasão de curso superior ? Avaliação do Programa Bolsa Universitária de Goiás

In 2010, an earthquake hit Haiti and caused thousands of citizens from that country to migrate to Brazil. Therefore, this dissertation aims to analyze how the insertion of Haitian immigrants in the Brazilian labor market takes place, assuming that they are occupied in the segments in which they have greater comparative advantages in relation to the Brazilians nationals. Thus, we estimate typically Mincerian equations through quantile regressions in addition to an Oaxaca-Blinder decomposition in a sample with Haitians, Brazilians in the same occupations and natives in other jobs from the 2019 Annual List of Social Information (RAIS). It is verified that the average salary of those who are working in occupations considered to be Haitian is lower, which may be an indication of the inferior quality and precariousness of these jobs. Furthermore, evidence is found that the wage determinants act differently for each group, valuing Brazilian workers more. In this context, Haitians act as complements to Brazilians who are in different occupations and as substitutes for those who work in the same positions, but only in the lower income brackets.
