Estimadores de cume de função translog de produção agrícola evidência adicional e inferências para política
Authors: Brandt S.A. , Oliveira J.A.S. , Lemos J.J. Souza
Published: July 2016

A translog production function is fitted to farm census (1970-75) data by new ridge regression procedures. The results indicate that: (a) CD, CES and Leontief specifications would be rejected as appropriate representations of farm technology; (b) constant returns to scale are indicated for average size farms, and increasing returns to scale for large size farms; (c) there is not enough evidence to reject the usual hypothesis of unitary elasticity of substitution between labor and capital. Other elasticities of substitution are also high and positive. Implications for farm policy are drawn on those results.
On equilibrium with price rigidities and rationing
Authors: Escudé Guillermo
Published: July 2016

Properties of a price dependent rationing scheme are formulated which can handle constrained flexible prices as well as fixed prices. This scheme is applied to prove the existence of an equilibrium which generalizes Benassy's concept of K-equilibrium.
Price discrimination and the peak load problem
Authors: Craven John
Published: July 2016

The pricing policy of a public utility that faces a demand which varies cyclically is examined with respect to its welfare effects. The conventional first best, marginal cost pricing principle is assumed to have prohibitive administrative costs. Two second best alternatives - a "maximum demand tariff" and "price discrimination according to demand peakiness" are examined for their optimality with regard to maximising producers ' and consumers' surplus. The optimal maximum demand tariff is shown to yield more total welfare and to be a Pareto improvement on the ohter.

Economics of information and the theory of economic development
Authors: Stiglitz J.E.
Published: July 2016

This paper shows how recent developments in the economics of information can provide insights into economic relations in less developed countries, and how they can provide explanations for institutions which, in neoclassical theory, appear anomalous and/or inefficient. Sharecropping and other tenancy relationships in the rural sector and wage determination and urban unemployment are both investigated within this perspective.
Measurement of resource transfers from agriculture: brazil, 1950-1974
Authors: Oliveira João do Carmo
Published: July 2016

This article provides a measure of the substantial role Brazilian agriculture has played in the formation of urban capital during the Import Substitution Industrialization period as a result of implicit transfers. These implicit transfers were associated with divergences between the Intersectoral Terms of Trade and their shadow-value. The work shows that as industrialization intensified, from the mid 50's on, these divergences increased, so that a very large transfer of resources from agriculture took place. A highly subsidized rural credit policy (for modern input purchase) has been in operation since the mid 60's. However, while the policies affecting the agricultural product prices have taxed all producers evenly, the credit policy has only benefited the already well-off and most technologically advanced sections within agriculture. Thus, the rapid capital formation and the implicit tax burden, which the product price and input credit policies implied, have been highly selective and discriminatory, not only between agricultural and non-agricultural sectors as is usually admitted "a priori", but also within agriculture.
Análise do desempenho dos candidatos aos cursos da ANPEC, 1976-1982
Authors: Aguiar Sílvio , Aguirre Antônio , Soares José Francisco
Published: July 2016

The National Association of Postgraduate Studies in Econornics (ANPEC) administers yearly the entrance examination for candidates all over Brazil. In this paper we report the main results of an statistical analysis of the grades obtained by candidates in the period 1976-1982. The grades correspond to four subjects: Macroeconomics, Microeconomics, Statistics and Mathematics. We used Factor Analysis to justify the summarization of those faur grades into two, namely Economic Theory and Quantitative Methods. We also used Multiple Analysis of Variance to study those two response variates in relation to three factors of classification. In addition to trying to identify differences in the candidates levels with reference to the same factors, we investigated possible interactions among the factors, and produced several classifcations of the centers.
Contratos salariais justapostos e política anti-inflacionária
Authors: Simonsen Mario Henrique
Published: July 2016

The present paper analyses the problems of anti-inflationary policies facing overlapping wage contracts. It extends the pioneer conclusions of Stanley Fischer and John Taylor in late seventies, showing thatl with overlapping wage contracts monetary policies can affect real economic variables, even under rational expectations. Two important conclusions are that anti-inflatíonary policies open a door to temporary real wage increases without adverse side-effects on outpout and employment. And that, with overlapping wage contracts inflation cannot be sopped immediatly if nominal wages cannot be cut. The paper also discusses a number of propasals to synchronize wage adjustments moving from the overlapping contract structure to perfect indexation.
The estimation of dynamic models with missing observations
Authors: Harvey A. C. , Pereira Pedro Luiz Valls
Published: July 2016

An ARMA model can be put in state space form and its exact likelihood function calculated by the Kalman filter. The same technique can be extended to handle missing observations, including cases where the data are initially available at an annual level and subsequently become available on a quartely, or monthly, basis. The Kalman filter enables the likelihood function to be computed for both stock and flow data. Once a suitable model has been fitted, the missing observations may be estimated by "smoothing". The paper first sets out the Kalman filter approach to missing observations for an ARMA time series model and discusses the implementation of an efficient algorithm. The results are then extended to cover static regression models with ARMA disturbances and dynamic models. A series of Monte Carlo experiments comparing the efficiency of different estimation procedures are reported.

Alguns aspectos da teoria dos jogos e uma aplicação ao problema da dívida externa
Authors: Roza Solange de Oliveira
Published: July 2016

Until recently, the most interesting application of infinitely repeated games was the study of cooperative oligopolies. Here, an application of the game theory approach is done to the case of the external debt, consídering as player the lenders in time periods and some conclusions come abroad in cases of cooperative or non-cooperative strategies. The cooperative strategy can be understood as a concession of additional lendings by the lenders. Analizing the problem of the external debt as a static game, we conclude that the adoption of a cooperative strategy by the lenders can avoid losses implied by a non-cooperative strategy. With base in the approach of repeated games the conclusion is that the cooperative solution can be obtained as a non-cooperative equilibrium of the infinitely repeated game.
Estimação do hiato do produto via componentes não observados
Authors: Pereira Pedro Luiz Valls
Published: July 2016

The Product Gap is usually defined by the difference between the logarithm of potential product and that of effective product, the former being defined by the estimate of the level that the real product would reach if there were full employment. Sustained growth is implicit in the definition of potential product. Some authors (such as Moreira (1985)) have criticized this formulation, and suppose that when entrepreneurs consider the industrial product, they make a provision for the year's growth using the average rate of the two previous years. Also, investments are realized so as to maintain the utilization of the industrial complex at a constant level. This article presents an alternative way of defining potential product, one associated with the traditional formula. This new formulation defines potential product by the trend componentof the effective product series, with the possible presence of other components such as cyclical and seasonal. Effective product may therefore be interpreted as a temporal series that can be broken up into non-observed components, i.e., a structural model in the terminology of Harvey (198S}. The estimate of the non-observed components is made by Kalman's Filter; as a by-product we have the estimate of the product gap as the difference between effective product and the trend component. Another by-product that may be obtained is a series of effective and potential product on a different level from the observational.
Uma nota sobre as importações brasileiras de produtos manufaturados
Authors: Moraes Pedro Bodin de
Published: July 2016

There have been several estimations for an import demand equation in Brazil. All the authors have used annual data, in the absence of information for output on a quarterly basis in this paper we have used an output series recently calculated by Modiano and Lopes (1985) to estimate an import demand equation for the period 1976.I - 1984.IV. We attempted to capture import rationing by including net reserves/ external debt as ao explicative variable in our regressions. The estimatives obtained are reported in Section 2. In Section 3 we present some progressions for the evolution of the import volume munder different assumptions on the output rate of growth.

Missing observations in stochastic difference equation with arma errors
Authors: Pereira Pedro L. Valls
Published: July 2016

This paper considers the estimation of stochastic difference equation with missing observations. Time series data is available at different levels of aggregations. The most common is the annual-quarterly model, where for the first part of the time series data, some of the endogenous and/or exogenous variables are available on an annual basis and the second part on a quarterly basis. A method of estimation, based on the Kalman Filter, enables us to obtain the exact maximum likelihood estimates of the model.

A nominal theory of the nominal rate of interest and the price level with the integration of both the asher effect and the gibson paradox
Authors: Martins Marco Antonio Campos
Published: July 2016

This paper develops a simple theory of nominal income interest determination under three key assumptions: firstly, the only relevant distinction between money and government bonds lies in their holding periods. Secondly, individuals take full account of the government budget constraint and do not concern themselves with discounting future tax liabilities associated with the issue of government bonds. Finally, the model incorporates a private credit market for individuals borrowings and lendings. According to this theory, the nominal rate of interest is determined by two separable influences,the bond/money ratio and the rate of expansion of the money supply. The first of these influences can give rise to a positive correlation between nominal interest rates and price levels and the second can generate a close relationship between the level of these nominal rate and the rates of expansion of the price level. Therefore, this theory coherently accounts for both the Gibson Paradox and the Fisher-effect.

Diferenciais de salário: questões metodológicas e ilustrações
Authors: Barros Ricardo Paes de , Pontes Jaime Pereira de , Varandas Simone
Published: July 2016

The objective of this paper is threefold. First, it seeks to stress the importance of the sensitivity of wage differentials to the set of control variables used. Secondly, the nature of this sensitivity is investigated, that is, how the properties of the control variables are related to the magnitude and direction of their influence on the estimated wage differentials. Finally, the paper presents a study of the effect of possession of work documents on the wage level, with an example and counter-example, the latter being a case of how an increase in the number of control variables does not necessarily lead to a reduction of the wage differential

Dynamic Specification of The Demand for Currency. An Application of Co-integration Techniques. Argentina 1977-1988
Authors: Ahumada Hildegart
Published: July 2016

This study presents a model of the demand for currency in a complex highly-inflationary enviroment: Argentina 1977-1988. The econometric serach of a model - which can be considered as a satisfactory approximation of the data generating process o real cash balances - focussed, at this stage, on a group of "basics" variables given by usuak economic theories of the demand for money. Firstly, the porpuse is to concentrate on the "long-run" determinants usingt an information set which includes interest rates, domestic prices and transactions. Co-integration technics, proposed by Granger and Engle (1987) are applied in order to evaluate a "long-run" hypothesis. Data information are also used to specify the dynamic of the model following the methodology "general - to - particular" developed by Hendry et. al. The model selected incorporates a linear correction mechanism and an asymetric effect mof inflation. It has a suitable economic interpretation and satisfied a set of criteria to be considered as a "tentative" approximation to be underlying data generating process of real cash balances.

O grande mérito desse livro é tratar de maneira relativamente simples e didática vários desenvolvimentos recentes da econometria. Há, por exemplo, várias seções apresentando o conceito de expectativas racionais e analisando suas implicações ao se estimar um modelo de oferta e demanda para um produto. Em outra seção é explicada com clareza a distinção entre o modelo de regressão censurada (modelo de Tobin) e o modelo de regressão truncada. Cabe destacar, também, o último capítulo, onde são apresentados métodos de análise de resíduos, seleção de modelos e testes sobre a especificação da equação de regressão. Trata-se, portanto, de um livro didático que abrange vários tópicos que não são encontrados em outros textos introdutórios de econometria.
An Equilibrium Theory of the Business Cycle Under Certainty
Authors: Martins M.A.C.
Published: July 2016

This paper develops a full-employment theory of the business cycle in the context of a simple equilibrium dynamic monetary model with complete information, overlapping generations and production processes. This theory is founded on three basic notions: (a.) economic agents plan to limit their own freedom of action; (b) it takes time to produce one unit of output; the productive input can be employed on alternative discrete overlapping production processes at each point in time. According to this theory, fully anticipated monetary shocks cause the kind of movements in outputs, prices and nominal incomes, which are well known as the business cyde.
A Teoria da Renda Permanente e os Movimentos Estocásticos do Consumo
Authors: Neto Francisco Cribari
Published: July 2016

In this paper we present the discussion about the stochastic implications af the Permanent Income Theory. It is shown that consumption must follow a random walk with drift if the theory is true. An empirical investigation of consumption in USA and Canada shows that we can reject the Keynesian Theory and cannot reject the Permanent Income Theory. However, we find that the intertemporal nature of consumption is stronger than predicted by the Permanent Income Theory.

Os indivíduos passam parcela considerável do seu tempo no ambiente de trabalho e se observa que, embora existam organizações que voltam a atenção para a Qualidade de Vida no Trabalho, também encontramos aquelas que estão preocupadas apenas com lucro e tratam seus funcionários como recursos financeiros ou materiais, deixando de reconhecê-los como potenciais talentos. Dentro deste contexto, realizou-se um estudo de caso, de natureza exploratória, com o objetivo de aprofundar e detalhar informações sobre a percepção dos colaboradores (servidores e contratados) lotados na Célula de Desenvolvimento de Pessoas da Gerência Regional de Educação (GRE) de Petrolina, enfocando a Qualidade de Vida no Trabalho. A investigação utilizou o modelo desenvolvido por Fernandes (1996), que leva em consideração nove dimensões. Para coleta de dados foi elaborado questionário, respondido por 15 colaboradores. Ressalta-se, que a melhoria dos fatores causadores de mal-estar, não depende apenas da GRE, mas principalmente da alta administração do órgão.

Glosas de Materiais Especiais de um Hospital Privado em Recife - PE
Authors: Souza Marta Gerusa Silva de , Souza Carla Giselly de , Cintra Grace Mary Gomes
Published: July 2016

A palavra Auditoria vem do latim Auditore, que significa aquele que ouve. É o perito encarregado de examinar contas. O processo de auditoria consiste em analisar documentos, registros ou outras informações e depois comparar com uma norma ou requisito pré-estabelecido. A glosa é o cancelamento parcial ou total destes orçamentos, por serem considerados ilegais ou indevidos, ou seja não cabível ao pagamento. Quando as instituições de saúde têm suas contas glosadas, elas podem utilizar os recursos de glosas para recuperar suas perdas econômicas. Cada vez mais, as Órteses, Próteses e Materiais Especiais - OPME's - assumem importância econômica nas contas hospitalares. As compras desestruturadas e sem a homologação adequada de especialistas para os procedimentos prescritos geram um aumento de custo em sinistros sem o alcance da qualidade necessária para o melhor tratamento do paciente. O percentual de glosas em pacote é de 100%, isto é devido a falta de contrato entre a operadora do plano de saúde e o hospital, que desde 2006 não negocia novo contrato. O índice de glosa em OPME em geral, ainda é considerado alto, pois o aceitável é até 10%. Do numero total de cirurgias realizadas pelo plano de saúde durante o período de estudo o uso de OPME’s perfizeram um total de 52,21% nas contas analisadas. Para evitar a ocorrência de glosas em OPME’s é primordial que se tenha a solicitação médica, esta deve ser clara e objetiva e deve conter laudo, método escolhido e material a ser utilizado, anexado ao exames. A confecção de uma tabela de OPME’s com os materiais e rendimentos (preços), seria importante para evitar a glosa.

As atividades laborais em toda sua diversidade e importância geram, sobre a sociedade, o autor das mesmas e sobre a instituição a qual se integra, reflexos de sua expressão social e pessoal. No entanto, em se tratando da atividade docente, vale lançar um olhar sobre as condições exaustivas do cotidiano da prática da docência e suas consequências à saúde psicosociofisiológica do docente. A pesquisa tem como objetivo verificar os inúmeros fatores estressores que fazem do trabalho do docente uma profissão predisposta ao desenvolvimento de estresse ocupacional. Podendo inclusive desencadear um quadro de síndrome de burnout. Tendo seu desempenho comprometido pela situação de constante exaustão emocional e desumanização a que ele é submetido nas unidades escolares, de modo que os resultados refletem não só no professor, mas, também, na escola e no processo de ensino aprendizagem. Este trabalho é de cunho bibliográfico, descritivo e qualitativo. Foram feitos estudos preliminares para selecionar livros e artigos nas bases de dados “scielo” e portal do Ministério da Educação e Cultura – MEC, produzidos no período de 1994 a 2014, que mencionassem as palavras “estresse ocupacional” “professores” e “psicologia”.

COVARIANT INTEGRAL QUANTIZATIONS AND THEIR APPLICATIONS TO QUANTUM COSMOLOGY
Authors: Gazeau Jean-Pierre
Published: July 2016

We present a general formalism for giving a measure space paired with a separable Hilbert space a quantum version based on a normalized positive operator-valued measure. The latter are built from families of density operators labeled by points of the measure space. We especially focus on group representation and probabilistic aspects of these constructions. Simple phase space examples illustrate the procedure: plane (Weyl-Heisenberg symmetry), half-plane (affine symmetry). Interesting applications to quantum cosmology (“smooth bouncing”) for Friedmann-Robertson-Walker metric are presented and those for Bianchi I and IX models are mentioned.
ON IMMERSION FORMULAS FOR SOLITON SURFACES
Authors: Grundland Alfred Michel , Levi Decio , Martina Luigi
Published: July 2016

This paper is devoted to a study of the connections between three different analytic descriptions for the immersion functions of 2D-surfaces corresponding to the following three types of symmetries: gauge symmetries of the linear spectral problem, conformal transformations in the spectral parameter and generalized symmetries of the associated integrable system. After a brief exposition of the theory of soliton surfaces and of the main tool used to study classical and generalized Lie symmetries, we derive the necessary and sufficient conditions under which the immersion formulas associated with these symmetries are linked by gauge transformations. We illustrate the theoretical results by examples involving the sigma model.
LAPLACE EQUATIONS, CONFORMAL SUPERINTEGRABILITY AND BÔCHER CONTRACTIONS
Authors: Kalnins Ernest G. , Miller, Jr Willard , Subag Eyal
Published: July 2016

Quantum superintegrable systems are solvable eigenvalue problems. Their solvability is due to symmetry, but the symmetry is often ``hidden''.
The symmetry generators of 2nd order superintegrable systems in 2 dimensions close under commutation to define quadratic algebras, a generalization of Lie algebras. Distinct systems and their algebras are related by geometric limits, induced by generalized Inönü-Wigner Lie algebra contractions of the symmetry algebras of the underlying spaces. These have physical/geometric implications, such as the Askey scheme for hypergeometric orthogonal polynomials. The systems can be best understood by transforming them to Laplace conformally superintegrable systems and using ideas introduced in the 1894 thesis of Bôcher to study separable solutions of the wave equation. The contractions can be subsumed into contractions of the conformal algebra  so(4,C) to itself. Here we announce main findings, with detailed classifications in papers under preparation.
School Entry, Compulsory Schooling, and Human Capital Accumulation: Evidence from Michigan
Authors: Hemelt Steven W. , Rosen Rachel B.
Published: July 2016

Extant research on school entry and compulsory schooling laws finds that these policies increase the high school graduation rate of relatively younger students, but weaken their academic performance in early grades. In this paper, we explore the evolution of postsecondary impacts of the interaction of school entry and compulsory schooling laws in Michigan. We employ a regression-discontinuity (RD) design using longitudinal administrative data to examine effects on high school performance, college enrollment, choice, and persistence. On average, we find that children eligible to start school at a relatively younger age are more likely to complete high school, but underperform while enrolled, compared to their counterparts eligible to start school at a relatively older age. In turn, these students are 2 percentage points more likely to first attend a two-year college and enroll in fewer total postsecondary semesters, relative to their older counterparts. We explore heterogeneity in these effects across subgroups of students defined by gender and poverty status. For example, we illustrate that the increase in the high school graduation rate of relatively younger students attributable to the combination of school entry and compulsory schooling laws is driven entirely by impacts on economically disadvantaged students.
Do all roads lead to Rome?: Modeling register variation with factor analysis and discriminant analysis
Authors: Egbert Jesse , Biber Douglas
Published: July 2016

Previous theoretical and empirical research on register variation has argued that linguistic co-occurrence patterns have a highly systematic relationship to register differences, because they both share the same functional underpinnings. The goal of this study is to test this claim through a comparison of two statistical techniques that have been used to describe register variation: factor analysis (as used in Multi-Dimensional analysis, MDA) and canonical discriminant analysis (CDA). MDA and CDA have different statistical bases and thus give priority to different analytical considerations: linguistic co-occurrence in the case of MDA and the prediction of register differences in the case of CDA. Thus, there is no statistical reason to expect that the two techniques, if applied to the same corpus, will produce similar results. We hypothesize that although MDA and CDA approach register variation from opposite sides, they will produce similar results because both types of statistical patterns are motivated by underlying discourse functions. The present paper tests this claim through a case-study analysis of variation among web registers, applying MDA and CDA to analyze register variation in the same corpus of texts.
Damages paid to taxpayers for issuing an unlawful tax decision – public expenditure which may be avoided
Authors: Drywa Anna
Published: July 2016

One of the categories of public expenditure are, inter alia, funds intended to pay as compensation to taxpayers who have been harmed by the tax authorities as a result of issuing faulty tax decision. The purpose of this article is to draw attention to the fact that these are expenses that can be avoided.

Liability is one of the foundations of a democratic state of law. It is not permitted to hand over taxpayer risk associated with the exercise of power. All damages caused to the taxpayer as a consequence of faulty tax decision should be compensated. Therefore, minimizing the amount of compensation should be done by preventing contempt of the law and improving the quality of tax legislation.
Will Transcatheter Aortic Valve Replacement (TAVR) be the Primary Therapy for Aortic Stenosis?
Authors: Condado Jose F. , Block Peter C.
Published: July 2016

Transcatheter aortic valve replacement (TAVR) is increasingly used for the treatment of high or very high surgical risk patients with severe aortic stenosis (AS) or failing surgical bioprosthesis (valve-in-valve, VIV-TAVR). In TAVR, the collapsed transcatheter heart valve (THV) is introduced using the delivery system inserted from the femoral artery (preferred) or other alternative accesses (transapical, transaortic, transcarotid, subclavian/transinnominate or transcaval). The delivery system is then advanced until coaxially aligned with the aortic annulus, where the THV is deployed. This procedure can be associated with complications such as access site injury (vascular complication), paravalvar leak, cerebrovascular events and conduction disturbances. However, the rapid acceptance and successes observed with TAVR have been made possible through careful patient selection, preprocedural planning (i.e. MDCT annular sizing), THV technology (i.e. new generation valves), and procedural techniques (i.e. minimalist TF-TAVR and alternative percutaneous access options), as well as a decrease in complications as TAVR experience grows. Though the results or ongoing clinical trials evaluating TAVR in intermediate surgical risk patients are pending, it is likely that TAVR will soon be approved for lower risk patients as well.
Coronary Artery Chronic Total Occlusion
Authors: Choi Calvin , Agarwal Nayan , Park Ki , Anderson R. David
Published: July 2016

Coronary artery chronic total occlusion (CTO) is defined as an occluded coronary artery segment without anterograde flow for at least three months. It can be classified as a “true” or “functional” CTO based on flow characteristics. In “true” CTO, there is no anterograde flow. In “functional” CTO, there is minimal anterograde flow through the occluded segment of the coronary artery. CTO is a common finding during coronary angiography and its prevalence may vary depending on the reported literature. Among patients without previous coronary artery bypass grafting (CABG), CTO is found in about 20–30% of the patients. CTO may develop insidiously over a period of time and involve a complex interplay between intracellular and extracellular factors, smooth muscle and foam cells, calcification, and neovascularization. There is a growing body of evidence to support that CTO revascularization may improve clinical outcome when compared to medical management. Both the European and American cardiovascular societies support CTO revascularization with a class 2a recommendation (level of evidence B). Historically, due to low procedural success rate, apparent inefficient resource utilization, potential increase in complication rates and uncertain clinical benefits, only about 10–20% of patients with CTO are treated with percutaneous coronary intervention (PCI). Recent advances using novel and innovative techniques with dedicated equipment have significantly improved the procedural success rate for CTO PCI to about 90% in the hands of experienced operators. With increasing interest in CTO PCI coupled with increased educational effort, CTO PCI likely will become more accessible to patients in need of CTO revascularization. Ongoing advancement in innovative techniques and equipment will continue to improve procedural success rates and reduce procedural complication rate for CTO PCI. Furthermore, there are a number of prospective clinical trials on the horizon which should help define the clinical benefits and limitations of CTO PCI in the near future.
