Hiperinfla??o: um arcabou?o teórico
Barbosa, Fernando de Holanda;Sallum, élvia Mureb;
Revista Brasileira de Economia , 2002, DOI: 10.1590/S0034-71402002000400001
Abstract: este artigo apresenta uma teoria da hiperinfla??o na qual n?o há necessidade de apelar-se para hipóteses casuísticas, como expectativas adaptativas, ajustamento parcial no mercado monetário ou profecias auto-realizáveis. o modelo tem um agente representativo com vida infinita que aloca seus recursos de sorte a maximizar o bem estar, todos os mercados est?o em equilíbrio, o banco central financia o déficit público e a moeda é essencial. a hiperinfla??o ocorre porque a restri??o intertemporal do governo n?o é satisfeita. o arcabou?o teórico produz algumas conclus?es sobre a dura??o da hiperinfla??o, e sobre outras características deste processo, nem sempre em concordancia com a sabedoria convencional. o artigo também analisa como o fen?meno da substitui??o da moeda, um fato estilizado das experiências hiperinflacionárias, pode afetar a essencialidade da moeda, um ingrediente básico do modelo.

Abstract: Este artigo apresenta uma teoria da hiperinfla o na qual n o há necessidade de apelar-se para hipóteses casuísticas, como expectativas adaptativas, ajustamento parcial no mercado monetário ou profecias auto-realizáveis. O modelo tem um agente representativo com vida infinita que aloca seus recursos de sorte a maximizar o bem estar, todos os mercados est o em equilíbrio, o banco central financia o déficit público e a moeda é essencial. A hiperinfla o ocorre porque a restri o intertemporal do governo n o é satisfeita.

A paridade do poder de compra: existe um quebra-cabe?a?
Barbosa, Fernando de Holanda;
Estudos Econ?micos (S?o Paulo) , 2009, DOI: 10.1590/S0101-41612009000300001
Abstract: this paper shows that the purchasing power parity puzzle is a statistical artifact produced by the fact that the long run equilibrium real exchange rate is not constant, but changes throughout time. this fact implies that the inertia coefficient has an upward bias.
O valor da moeda e a teoria dos pre?os dos ativos
Barbosa, Fernando de Holanda;
Revista Brasileira de Economia , 2005, DOI: 10.1590/S0034-71402005000200005
Abstract: the price of money, as the price of any financial asset, can be determined through asset pricing theory. based on this approach, this paper presents a concise survey of the following topics of monetary theory: i) price of money: bubbles versus fundamentals; ii) multiple equilibria; iii) price level indeterminacy; iv) optimum quantity of money; v) hyperinflation; vi) currency substitution, and vii) price of money rigidity.
The contagion effect of public debt on monetary policy: the Brazilian experience
Barbosa, Fernando de Holanda;
Revista de Economia Política , 2006, DOI: 10.1590/S0101-31572006000200004
Abstract: this paper attempts to explain why the brazilian inter-bank interest rate is so high compared with rates practiced by other emerging economies. the interplay between the markets for bank reserves and government securities feeds into the inter-bank rate the risk premium of the brazilian public debt.
Banco Nacional: jogo de Ponzi, PROER e FCVS
Barbosa, Fernando de Holanda;
Revista de Economia Política , 2008, DOI: 10.1590/S0101-31572008000100005
Abstract: banco nacional: ponzi game, proer and fcvs. this paper analyses the causes of the failure of banco nacional and the resolution method adopted by the brazilian central bank. the program (proer) designed by the central bank and its legal framework allowed the failed bank to buy " defaulted securities" , financed by the central bank, and to use them as borrowing collateral. the paper also analyses the private and social costs of this bank failure.

A carreira de professor estadual no Brasil: os casos de S o Paulo e Rio Grande do Sul State school teacher career in Brazil: the cases of S o Paulo and Rio Grande do Sul
Fernando de Holanda Barbosa Filho,Samuel de abreu pess?a
Revista de Administra??o Pública , 2011, DOI: 10.1590/s0034-76122011000400004
Abstract: O presente artigo, com base nas folhas de pagamentos dos professores das redes públicas estaduais do Rio Grande do Sul (RS) e de S o Paulo (SP), mostra que a remunera o dos professores das redes públicas destes estados n o está relacionada com o desempenho dos professores, sendo o tempo de servi o o fator determinante na evolu o da remunera o. O salário relativo médio de um professor da rede dos estados do Rio Grande do Sul e de S o Paulo, como fra o do PIB, é superior ao encontrado em outros países que s o considerados exemplos de bom desempenho escolar. Ou seja, n o há evidência de que o salário nestas redes esteja fora da nor-ma tomando como compara o os países da OECD. O artigo mostra, ainda, que o salário médio pago aos professores da ativa é inferior ao benefício médio concedido aos inativos e que estes apresentam um elevado custo na folha de pagamentos dos estados, superior aos 50% no Rio Grande do Sul e 35% em S o Paulo. Mais, as regras para aposentadoria dos professores no Brasil s o extremamente generosas quando comparadas com outros países do mundo. O artigo finaliza documentando a forte compress o salarial existente no magistério em compara o ao observado no mercado de trabalho gaúcho e paulista para os profissionais com curso superior. This paper establishes some stylized facts about the public educational system of two Brazilian states: Rio Grande do Sul (RS) and S o Paulo (SP). First, this paper shows that teachers' wages are not related with their productivity because wages are mainly affected by tenure. Second, teachers' average wage as fraction of GDP is higher than the one paid in other countries considered example of educational achievements, i.e., there is no evidence that the wages paid in Rio Grande do Sul and S o Paulo underpay its teachers, comparing with OCDE countries. Third, the average wage paid to teachers is inferior than the average benefit paid to retired teachers, and retirees represent a heavy burden on this states wage bill, above 50% at Rio Grande do Sul and 35% at S o Paulo. Moreover, the paper shows this states retirement rules are extremely generous comparing with other countries. Fourth, the public teachers' wage compression is stronger than the one observed in the job market for workers' with a college degree in both states.
Produtividade e convergência entre estados brasileiros: exercícios de decomposi??o setorial
Canêdo-Pinheiro, Mauricio;Barbosa Filho, Fernando de Holanda;
Economia Aplicada , 2011, DOI: 10.1590/S1413-80502011000300004
Abstract: this paper uses shift-share decomposition techniques to analyze the evolution of the brazilian labor productivity and convergence among brazilian states. the period 1985-1995 is characterized by widespread and severe drop in productivity, with weak convergence and an important role of the component associated with structural changes of state economies. in the period 1995-2005 brazilian productivity had a slow recovery, a s?o paulo state phenomenon, driven by its industry. in most states productivity showed with predominant role of the component associated with growth within the significant recovery. not by chance the speed of convergence has accelerated, sectors. moreover, the productivity convergence has been driven mainly by industrial and services sectors, replicating the european evidence.
Morphological and chemical analysis of bone substitutes by scanning electron microscopy and microanalysis by spectroscopy of dispersion energy
Cruz, Gabriela Alessandra da;Toledo, Sérgio de;Sallum, Enilson Antonio;Lima, Antonio Fernando Martorelli de;
Brazilian Dental Journal , 2007, DOI: 10.1590/S0103-64402007000200008
Abstract: this study evaluated the morphological and chemical composition of the following bone substitutes: cancellous and cortical organic bovine bone with macro and microparticle size ranging from 1.0 to 2.0 mm and 0.25 to 1.0 mm, respectively; inorganic bovine bone with particle size ranging from 0.25 to 1.0 mm; hydroxyapatite with particle size ranging from 0.75 to 1.0 mm; and demineralized freeze-dried bone allograft with particle size ranging from 0.25 to 0.5 mm. the samples were sputter-coated with gold in an ion coater, the morphology was observed and particle size was measured under vacuum by scanning electron microscopy (sem). the chemical composition was evaluated by spectroscopy of dispersion energy (eds) microanalysis using samples without coating. sem analysis provided visual evidence that all examined materials have irregular shape and particle sizes larger than those informed by the manufacturer. eds microanalysis detected the presence of sodium, calcium and phosphorus that are usual elements of the bone tissue. however, mineral elements were detected in all analyzed particles of organic bovine bone except for macro cancellous organic bovine bone. these results suggest that the examined organic bovine bone cannot be considered as a pure organic material.
