Institutional Challenges for Brazil’s Economists

This article consists of the author’s address thanking ANPEC for the honor bestowed on him. It begins by mentioning a list of Brazilian economists with whom he associated and who were crucial in creating the institutional structure which made it possible for the profession to grow. The author then outlines what he considers to be some of the intellectual challenges to Brazil’s economics profession in the coming years.Research, Institutions, Groups, Bureaucracy, Agribusiness, Education,Service Sector

Boundary Value Problems for Elliptic Differential Operators of First Order

We study boundary value problems for linear elliptic differential operators of order one. The underlying manifold may be noncompact, but the boundary is assumed to be compact. We require a symmetry property of the principal symbol of the operator along the boundary. This is satisfied by Dirac type operators, for instance. We provide a selfcontained introduction to (nonlocal) elliptic boundary conditions, boundary regularity of solutions, and index theory. In particular, we simplify and generalize the traditional theory of elliptic boundary value problems for Dirac type operators. We also prove a related decomposition theorem, a general version of Gromov and Lawson's relative index theorem and a generalization of the cobordism theorem.Comment: 79 pages, 6 figures, minor corrections, references adde

From technology absorption to technology production: industrial strategy and technological capacity in Brazil's development process

This article surveys the evolution of technology policy in Brazil from its inception to the present day, examining the changes that it has undergone along the way. Having sketched in the apropriate background, it goes on to discuss the broad technological impact of rapid liberalization in the 1990s

Increasing the {\nu} = 5 / 2 gap energy: an analysis of MBE growth parameters

The fractional quantized Hall state (FQHS) at the filling factor {\nu} = 5/2 is of special interest due to its possible application for quantum computing. Here we report on the optimization of growth parameters that allowed us to produce two-dimensional electron gases (2DEGs) with a 5/2 gap energy up to 135 mK. We concentrated on optimizing the MBE growth to provide high 5/2 gap energies in "as-grown" samples, without the need to enhance the 2DEGs properties by illumination or gating techniques. Our findings allow us to analyse the impact of doping in narrow quantum wells with respect to conventional DX-doping in AlxGa1-xAs. The impact of the setback distance between doping layer and 2DEG was investigated as well. Additionally, we found a considerable increase in gap energy by reducing the amount of background impurities. To this end growth techniques like temperature reductions for substrate and effusion cells and the reduction of the Al mole fraction in the 2DEG region were applied

The impact of politics on fiscal behavior: the case of Brazil

This paper examines the proposition that a government which faces an election or depends on general popular support to govern effectively will find it difficult to resist increasing expenditures or to raise taxes. The resulting fiscal deficits are then either financed by the central bank, which produces inflation, or by domestic and/or foreign borrowing, increasing the government's foreign or domestic debt. After a brief historical survey of Brazil, a method is use to test the validity of this hypothesis in a more formal way.Este artigo examina a proposição de que um governo que está enfrentando uma eleição ou que depende de um apoio popular para governar terá dificuldade de resistir ao aumento de gastos ou de aumentar os impostos. Os conseqüentes déficits fiscais podem ser financiados pelo Banco Central, o que resulta em inflação, ou pelos empréstimos domésticos e/ou estrangeiros, aumentando a dívida doméstica ou estrangeira. Depois de um curto resumo histórico da experiência brasileira, um método quantitativo está sendo utilizado para testar a validade desta hipótese de uma maneira mais formal
