Description
Summary:This Thesis studies three distinct problems between itself, even so connected for the instrument. In the firist chapter a model of endogenous technical progress is used to study the relations between growth of the agricultural productivity and the process of industrialization in a context of open economy. The concept of Dinamic Comparative Advantage is exhaustingly used and, additionally, seaechs to understand as the technological integration between the sectors agricultural and industrial contributed for the dynamics of the employ in the industry. In the second chapter a model of general equilibrium was used to analyze and to compare the effect of two fiscal adjustament rules: the rule of primary superÃvit proportional to the product and the rule of zero nominal deficit. In the constructed model the rules it was analyzed the impacts of these rules on the optimal allocations as well as on the welfare. In both the cases, the effect of short and long runs always are compared. Finally, the third chapter considers an alternative proofs of the HotellingÂs Lemma and ShephardÂs Lemma using new relations of duality in the theory of the production. The proofs proposals posses two advantages, relatively to the usual demonstrations, which are, not teh use of the known envelope theorem and the validity of the demonstration for interior points to the production set. === Esta tese estuda trÃs problemas distintos entre sÃ, embora conectados pelo instrumental. No primeiro ensaio à utilizado um modelo de progresso tÃcnico endÃgeno para estudar as relaÃÃes entre crescimento da produtividade agrÃcola e o processo de industrializaÃÃo num contexto de economia aberta. O conceito de Vantagem Comparativa DinÃmica à exautivamente utilizado e, adicionalmente, busca-se entender como a integraÃÃo tecnolÃgica entre os setores agrÃcola e industrial contribuà para a dinÃmica do emprego na indÃstria. No segundo ensaio utilizou-se um modelo de equilÃbrio geral do tipo agente representativo para analisar e comparar os efeitos da adoÃÃo de dois regimes de ajuste fiscal: o regime de superÃvit primÃrio proporcional ao produto e o regime de dÃficit nominal zero. No modelo construÃdo analisou-se os impactos de tais regimes sobre as alocaÃÃes de equilÃbrio bem como sobre o bem estar. Em ambos os casos, o efeito de curto prazo e de longo prazos sÃo sempre comparados. Por Ãltimo, o terceiro ensaio propÃe demonstraÃÃes alternativas dos Lemas de Hotelling e de Shephard utilizando novas relaÃÃes de dualidade na teoria da produÃÃo. As demonstraÃÃes propostas possuem duas vantagens, relativamente Ãs demonstraÃÃes usuais, quais sejam, a nÃo utilizaÃÃo do conhecido Teorema do Envelope e a validade da demonstraÃÃo para pontos interiores ao conjunto de produÃÃo.
