Amidst this debate, different economic schools of thought have been debating their visions and policies to face the problem. Here we intended to take part in this debate by building a growth model for the Brazilian economy which causes and is affected by climate change. In order to do that, we worked with two heterodox frameworks: stock-flow consistent models (SFC) and sraffian supermultiplier models. We’ve also compared the two major propositions in the literature: the limits to growth agenda and the decoupling hypothesis. In general, the latter seemed more effective in preventing economic collapse, while the first seemed less effective for the Brazilian case. 2022-01-01T00:00:00Z https://bibliotecadigital.dth.api.gov.br/handle/123456789/526025 Title: Gás para o desenvolvimento: perspectivas de oferta e demanda no mercado de gás natural do Brasil 2021-02-01T00:00:00Z https://bibliotecadigital.dth.api.gov.br/handle/123456789/526110 Title: Capital e trabalho no Brasil no século XXI: o impacto de políticas de transferência e de tributação sobre desigualdade, consumo e estrutura produtiva Abstract: The debate about inequality and income distribution has gained focus in the recent economic discussion, especially due to an income concentration trend verified in developed countries and the repercussion of “Capital in the twenty first century”, by Thomas Piketty. In Brazil, data and studies have pointed out to an inequality decrease in the first decade of the 2000s. Since a redistributive process may bring many impacts and they are interconnected, their implications deserve an investigation. The aim of this dissertation was to analyze the economic impacts of income redistribution in Brazilian economy. We developed a detailed database in order to build a Social Accounting Matrix (SAM) and a Computable General Equilibrium (CGE) model. The SAM presents a disaggregation by 10 representative households and the recursive dynamic CGE model is innovative since takes into account the SAM’s structure and flows, detailing the income generation and appropriation by different sources and the spending structure of the Brazilian economy. We applied the methodology to analyze two redistributive policies: the “Bolsa Família” Program (BFP) and a taxation on profits and dividends. The SAM indicators and the CGE results showed the economic growth process in Brazilian economy is associated with income concentration, so that, in the absence of structural changes or redistributive policies to mitigate these effects, the income concentration standard tends tobe reproduced. The results indicated the BFP also generates income gains for classes who do not receive cash transfers from Government, since the program indirect effects generates labor and capital income. An unprecedented conclusion is that, in addition to reduce income inequality from government transfers, the program has positive effects in reducing labor income inequality. Changes on income tax structure by fixing profits and dividends taxation associated with a reduction on labor income taxation would have potential to accelerate the inequality drop process in the Brazilian economy. Consumption and production oriented to domestic market would be encouraged. However, fixing tax on profits and dividends without reducing other taxes would bring an economic cost. The results suggest policies or redistributive phenomena have the potential to modify the productive structure for its effects on consumption, diversifying productive structure and investment, which may reduce long-term income concentration. We also conclude that a reduction in inequality does not imply economic cost, although its effect on growth is small. 2020-01-01T00:00:00Z https://bibliotecadigital.dth.api.gov.br/handle/123456789/526172 Title: O que aprendemos sobre o BNDES? Abstract: This article discusses the available empirical evidence about the Brazilian Development Bank (BNDES), one of the largest development banks in the world. Seventy academic papers that, based on the data, tried to identify causal relationships involving the Bank were reviewed. In general, the evidence indicates that BNDES loans are an effective instrument to increase investment, employment and exports, especially when credit borrowers are micro, small and medium-sized companies. The Bank also appears to have positive effects on economic activity and the turnover of supported firms. There is also evidence that the BNDES’s operation was able to reduce deforestation in the country. However, most articles suggest that the BNDES has null effects on productivity, the profitability of companies and the share value of supported firms. The literature is not conclusive about the effects of BNDES on the power of monetary policy and municipal tax collection, as well as about whether there was political influence in the Bank’s loans. Finally, this article discusses what is still unknown about the BNDES – which, therefore, remains an open issue for future research. 2020-07-01T00:00:00Z
