The first uses Granger causality in panel data to explore the causal relationships between economic and environmental variables. The results show that the effects of scale and technique are the main propagating channels of the emission flow. The second chapter makes an empirical investigation of the Green Solow model using non-parametric and semi-parametric techniques. The results are consistent with the hypothesis of declining marginal productivity of capital, the environmental Kuznets curve (EKC) and the convergence in emissions of CO2. However, there is no evidence of EKC and convergence in emissions of N2O and CH4. The third essay investigates the hypothesis of induced environmental change by testing Granger causality between oil price and productivity in the United States between 1949 and 2015. The results support the hypothesis of technical change induced by energy cost Publisher: Pontifícia Universidade Católica do Rio Grande do Sul Type: Tese 2019-03-01T00:00:00Z https://rd.uffs.edu.br/handle/prefix/3509 Title: Ensaios sobre business groups: Perdigão e Sadia e a consolidação de grupos econômicos no Brasil (1934-2009) Author: Zanela, Angelo Brião First advisor: Costa, Armando João Dalla Abstract: The objective of this thesis was to qualify Perdigão and Sadia as typical cases of business groups formed in Brazil between 1934-2009. Both companies began their expansion trajectories in the Midwest of Santa Catarina. Perdigão was founded by brothers Ponzoni and Brandalise in 1934 and Sadia by Attílio Fontana in 1944. The association between the two companies took place only in 2009, when the groups unified their operations, thus performing one of the stages of the merger process. Two years later it would be approved by the Administrative Council for Economic Defense (CADE), enabling the creation of Brasil Foods - BRF, one of the largest food companies in the world. It is believed that these events alone explain why the period of study was delimited between 1934-2009. From the interpretations of scholarly authors, this paper defined the Perdigão and Sadia structures as Business Groups by arguing that driven by the desire to grow more and more, either through family administration or through professionalized management, these groups faced structural and social difficulties inherents in the less developed economies, always seeking to maintain associative ties with their employees, since their managers understood that the success of the projects depended on a good relationship with people that were able to exercise their potential with creativity and satisfaction. In addition, Perdigão and Sadia adopted strategies aimed at vertical integration, diversification of products and activities, technological adaptations and insertion in the international market. These strategies were adopted in view of the perception that territorial boundaries did not present an ideal size for the growth of companies as industries. In addition, its managers wished to establish new activities, which would promote related complementary activities and intersectoral synergies that would increase the scope of their business and occupation in the domestic market. Perdigão and Sadia have always tried to stay ahead of their competitors and reduce the risks to be assumed due to the unstable institutional environment. More detailed analyzes on characteristics and strategies were developed from three essays (articles). The first, “Business Groups: Theoretical Review and Propositions on the Characteristics and Strategies of Economic Groups in Latin America”, presented the characteristics and strategies that help define business group models globally. Thus, the theoretical bases were established so that from the following essays, “Perdigão: Consolidated Business Group in Brazil (1934-2009)” and “Sadia as a Business Group Model in Brazil (1944-2009)”, the respective economic groups could be characterized as models of Business Groups and consolidated among the most important in the country.

This Program had as one of its main guidelines the improvement of health policy governance by the federated entities, with special attention to results management, materialized in the signing of the Management Commitment Term (MCT). This management policy was in force from 2006 to 2012, receiving the signature of 4,561 municipalities, representing 82% of the total Brazilian municipalities. In this way, the present thesis answered two questions: i) did the time of adhesion of the municipality to the program increase the efficiency levels of the Primary Care policies?; ii) has the improved efficiency provided by adherence to the "Pacto pela Saúde" reduced the health vulnerability between the participating municipalities? In response to these two questions, two empirical exercises were performed. First, the causal effect of the municipality's participation time in the program on an efficiency indicator of the primary health care policy was estimated using a Generalized Propensity Dose-Response Model (LECHNER, 1999; IMBENS, 2000). Second, the causal effect of the municipality's participation in the program on an indicator of municipal health vulnerability was estimated using the structural causal model proposed by Pearl (2000). The indicators of efficiency (IDEAB) and health vulnerability (IVS) were calculated using a multivariate Principal Component Analysis technique using specific information to the Primary health care model provided by the Ministry of Health. This research presents three contributions to the current literature. First, it analyzes in a pioneering and rigorous way the causal impact of the "Pacto pela Saúde" program. Second, it provides substantive evidence on how municipal health production responds to this policy. Third, it calculates specific municipal efficiency and vulnerability indicators for Primary Care. The main results of this thesis were: i) it was evidenced that the greatest time of adhesion to the Program occurred in municipalities with better health conditions and, therefore, more favorable to reach the agreed goals; ii) there is a positive correlation between time of adherence to the Program (dose) and efficiency indicator (IDEAB). The municipalities that acceded to the Program presented IDEAB higher, compared to the municipalities that did not adhere. In general, smaller municipalities (up to 10 thousand inhabitants) obtained better IDEAB's than larger municipalities; iii) There is a negative correlation between IDEAB and IVS; iv) a positive and significant impact of the Pacto pela Saúde on the efficiency indicator was estimated; v) positive and significant impact of the management efficiency provided by Pacto pela Saúde on the reduction of health vulnerability indicator of municipalities; vi) adequacy of the structural causal model and Pearl's (2000) back-door criterion of causal identification in the calculation of the effect of the Program on IVS Publisher: Universidade Federal do Paraná Type: Tese 2017-01-01T00:00:00Z
