SimulaÃÃes dos efeitos macroeconÃmicos do aumento dos investimentos pÃblicos no Brasil / Simulations of the macroeconomic effects of increased public investment in Brazil

Arley Rodrigues Bezerra 27 February 2013 (has links)
CoordenaÃÃo de AperfeiÃoamento de NÃvel Superior / O objetivo deste trabalho à construir um modelo de equilÃbrio geral,de modo a realizar simulaÃÃes contrafactuais dos recentes aumentos dos investimentos pÃblicos no Brasil, visando verificar efeitos nos agregados macroeconÃmicos, bem como no bem-estar social.Para a calibraÃÃo das variÃveis e parÃmetros do modelo foram utilizadas diversas bases de dados, inclusive IBGE, IPEADATA e Banco Central. Os exercÃcios consistem em alterar os valores dos parÃmetros referentes à proporÃÃo da composiÃÃo dos investimentos pÃblicos no qual no ano de 2010 os investimentos da administraÃÃo pÃblica, que se supÃem complementares aos investimentos privados, tiveram uma participaÃÃo de 53% da parcela dos investimentos pÃblicos em relaÃÃo ao PIB. Os investimentos das empresas estatais, que, por hipÃtese, sÃo substitutos dos investimentos privados, participaram com o complementar, 47%. A simulaÃÃo que direciona 80% dos investimentos pÃblicos à administraÃÃo pÃblica enquanto o restante 20% sÃo investidos pelas empresas estatais proporciona resultados de longo prazo no qual o produto cresceria cerca de 9,5%, enquanto o bem-estar cresceria 8%, de acordo com a medida proposta no trabalho. AlÃm disso, nas simulaÃÃes realizadas, mesmo na hipÃtese do capital das empresas estatais possuir maior produtividade que o capital privado,ganhos de bem-estar e crescimento poderiam ser obtidos. / The objective of this work is to build a general equilibrium model, in order to perform counterfactual simulations of recent increases in public investment in Brazil to check effects on macroeconomic aggregates, as well as in social welfare. For the calibration of the model parameters and variables were used several databases, including IBGE, IPEADATA and Central Bank. The exercises consist of changing the values of the parameters for the composition ratio of public investment in the year 2010 in which the investments of public administration, which are supposed to complement private investment, had a participation of 53% of the share of public investment to GDP. The investments of the state enterprises, which, by definition, are substitutes for private investment, participated with 47% complementary. The simulation that directs 80% of public investment to public administration while the remaining 30% is invested by state enterprises provides long-term results in which the product would grow about 9.5% while the welfare would grow 8%, according with the proposed measure on the job. Furthermore, in simulations performed, even if the capital of the state enterprises have higher productivity than private capital, gains in welfare and growth would be obtained.
