The Family Novel in the Emerging Nation-State: A Comparative Study of Ba Jin’s Jia and Lev Tolstoy’s Anna Karenina

The theme of family in literature and in popular discourse occurs at times when the family as an institution is under attack. Attacks against the family coupled with defence of the family are viewed as the barometer of people’s satisfaction with the society in which they live. This outpouring of emotion, whether it is in defence of or attacking the family, is the result of the family’s position on the bridge between nature and society – a fortunate (or a detrimental) link between an individual and the units that make up a society. Across the United States and much of the western world, the battle for gay marriage and inclusive civil unions has revealed the fissures in our collective moral view of the family. The conservative concern about the absence of ‘family values’ is magnified by our situation in a world of flux. Inflation, war, terrorist threats, and the depletion of natural resources are but a few examples. When so much is unknown, how do we position ourselves? What anchors us to the past, gives us comfort in the present, and supports us in the future if not the family? Alternatively, what coddles us more in the past, shackles us more to the present, and lulls us more into a fixed conception of the future than the family? My research is not a sociological survey into the family nor does it stake any claims to understanding the present state of the family in society. The study seeks, however, to shed light on the rhetorical uses of the family by analysing two novels that are inextricably concerned with the theory of the family in times of heightened social change. In particular, my research focuses upon the social role and political meaning of the family in Anna Karenina and Jia.

Assimetria informacional e precificação das ações das empresas negociadas na bolsa de valores de São Paulo : evidências a partir da faculdade de divulgar demonstrações contábeis em moeda constante a partir de 1996

Essa dissertação investigou, através de um estudo de eventos no mercado brasileiro de ações, se a divulgação de demonstrações contábeis em moeda constante, de uma empresa de capital aberto, produz efeitos no comportamento do preço de suas ações. A hipótese testada conduziu a investigação de que a política de divulgação das demonstrações contábeis em moeda constante, adotada pelas empresas de capital aberto, a partir de 1996, pode influenciar, significativamente, o processo de precificação de suas ações. Os resultados empíricos do trabalho evidenciaram que a forma de divulgação das demonstrações contábeis em moeda constante (completa, incompleta e omitidas) das empresas de capital aberto, produz efeitos significativos sobre o comportamento dos preços das suas ações, quando comparados os retornos das ações do grupo de empresas que divulgou de forma completa com o grupo de empresas com divulgação parcial ou que não divulgaram estas demonstrações, sendo que estes dois últimos grupos de empresas não apresentaram diferença significativa entre os retornos de suas ações.

Efeitos da variação da carga por eixo, pressão de inflação e tipo de pneu na resposta elástica de um pavimento

O presente trabalho é uma análise experimental que procura investigar os efeitos dos fatores carga por eixo, pressão de inflação e tipo de pneu sobre o desempenho de pavimentos. Os dados e informações existentes sobre o quadro de cargas por eixo praticada pela frota de veículos pesados é razoável. A ação conjunta dos referidos fatores é ainda uma questão pouco explorada. Assim, para compensar a escassez de dados sobre pressão de inflação e tipo de construção de pneus utilizados na frota de carga, programou-se uma pesquisa de campo na rodovia estadual RS/240. As informações oriundas da pesquisa demonstram que há um acréscimo generalizado no valor da pressão dos pneus e um aumento de uso dos pneus de fabricação radial em relação aos pneus convencionais. Os dados de campo subsidiaram a programação de um experimento fatorial cruzado executado na Área de Pesquisas e Testes de Pavimentos da UFRGS/DAER. A variação dos níveis dos fatores deu-se através de um simulador linear de tráfego atuando sobre uma pista experimental com 20 m de comprimento por 3,5 m de largura. Tendo como resposta estrutural do pavimento a máxima deflexão superficial recuperável medida com uma viga Benkelmam, determinou-se como significantes os efeitos dos fatores carga por eixo e pressão de enchimento dos pneus. Os cálculos estatísticos indicam também que não há diferenças significativas entre os pneus tipo 9.00R20 e 9.00x20 e que todas interações não exercem efeitos significativos sobre a variável de resposta. Em seqüência, determinaram-se as áreas de contato do rodado duplo do simulador de tráfego com a superfície do pavimento ensaiado para as combinações dos níveis dos fatores. Pode-se, então, comparar área de contato medida com área circular calculada, considerada em muitos modelos de dimensionamento de pavimentos. Relacionou-se a variação da pressão de contato com a deflexão recuperável e procedeu-se uma comparação da mesma com a pressão de inflação nominal dos pneus. Apresenta-se um modelo de análise do desempenho do pavimento em função da carga por eixo e da pressão de inflação, nos limites do experimento. Os dados decorrentes do experimento viabilizaram a determinação dos Fatores de Equivalência de Cargas para os níveis dos fatores, considerando-se o pavimento ensaiado. Avaliou-se, via evolução das deflexões e dos Fatores de Equivalência de Cargas, a redução da vida do pavimento, obtendo-se, para a combinação de níveis mais críticos de carregamento, resultados significativos de até 88 % de redução. Propõe-se, por último, uma formulação para o Fator de Equivalência de Cargas que considere também a ação da pressão de inflação.

Collective bargaining in Brazilian manufacturing, 1978-95

Collective bargaining, it is widely claimed, has been on the increase in Brazil since the late 1970s. This is seen as part of a broader change in Brazilian industrial relations towards a hybrid system of interest representation, in which elements of both the old state corporatism and pluralism now coexist. However, there is little or no systematic empirical evidence available to support this conclusion. This thesis addresses the question of the strengthening of collective bargaining as a method of job regulation in Brazil by providing a detailed empirical study. The questions of this study are: (a) how important has collective bargaining become in establishing provisions on the terms and conditions of the employment relationship which are not simply reproducing rules established via state regulation?; and (b) what factors accounted for changes in the content of these provisions? An analysis of 10,734 provisions in 287 collective agreements in manufacturing industries in the Metropolitan Area of Porto Alegre, the capital of the southernmost state of Rio Grande do Sul, was carried out for the period of 1978-95. This analysis offers support for the thesis that the significance of collective bargaining has increased. It shows that: (a) most substantive provisions created rules that were not established in other forms of regulation; (b) provisions that replicate the contents of regulatory legislation accounted for one out of seven substantive provisions, but in spite of being a copy of the law, these provisions are not entirely neutral for job regulation; (c) collective agreements also laid down substantive provisions benefiting employers, and not simply employees; and (d) the pace of change in bargaining outcomes oscillated with changes in the economic, legal and judicial contexts. This pace of change was mostly affected by (i) the rate of unemployment, (ii) the degree of openness of the economy to foreign competition, (iii) the capacity of employers to pass on costs to costumers, (iv) stabilisation policies aimed at curbing inflation, (v) the Federal Constitution made in 1988, (vi) the official rate of minimum wages, and (vii) the conduct of the labour judicial system in settling collective disputes.

The trasition from fixed to floating exchange rate regimes: the case of Brazil

This dissertation evaluates macroeconomic management in Brazil from 1994 to the present, with particular focus on exchange rate policy. It points out that while Brazil's Real Plan succeeded in halting the hyperinflation that had reached more than 2000 percent in 1993, it also caused significant real appreciation of the exchange rate situation that was only made worse by the extremely high interest rates and ensuing bout of severe financial crises in the intemational arena. By the end of 1998, the accumulation of internai and externai imbalances led the authorities to drop foreign exchange controls and allow the currency to float. In spite of some initial scepticism, the flexible rate regime cum inflation target proved to work well. Inflation was kept under control; the current account position improved significantly, real interest rates fell and GDP growth resumed. Thus, while great challenges still lie ahead, the recent successes bestow some optimism on the well functioning of this exchange rate regime. The Brazilian case suggests that successful transition from one foreign exchange system to another, particularly during financial crisis, does not depend only on one variable be it fiscal or monetary. In reality, it depends on whole set of co-ordinated policies aimed at resuming price stability with as little exchange rate and output volatility as possible.

Previsões de inflação com a curva de Phillips

O objetivo do trabalho investigar qualidade das previsões da taxa de inflação brasileira utilizando-se uma alternativa tradicional unemployment rate Phillips curve. Utilizaremos diversas variáveis que espelham nível de atividade econômica no Brasil em substituição ao hiato entre taxa de desemprego taxa natural de desemprego (NAIRU). Essas variáveis serão trabalhadas e baseado em critérios mencionados ao longo do estudo, serão classificadas por nível de erro de previsibilidade. objetivo ao final do trabalho sugerir indicadores variáveis de nível de atividade disponíveis publicamente que melhor possam interagir com dinâmica da inflação brasileira.

A inércia da inflação no regime de metas: os casos da Nova Zelandia, Reino Unido e Brasil

O objetivo da dissertação é avaliar o impacto da adoção do regime de metas na inércia da inflação. A inércia é analisada de acordo com procedimentos tradicionalmente adotados na literatura, através de modelos ARIMA. Em virtude das metas de inflação não serem imutáveis ao longo do tempo, propõe-se uma metodologia para se medir a inércia da taxa de inflação, onde esta possui dois componentes: a tendência e a parte transitória. A inércia da inflação será, então, medida pelo coeficiente com que a taxa de inflação converge para sua taxa de longo prazo.

Um estudo sobre os modelos operacionais dos bancos centrais autônomos no mundo

O projeto de lei do Senado de Nº 317 de 2003, que estabelece a autonomia operacional do Banco Central do Brasil, é um grande passo em direção a uma modernização institucional do país. Sendo essa autonomia aprovada, uma questão crucial que se segue é como será o desenho institucional do Banco Central do Brasil. Quais áreas estarão ligadas ao BACEN e quais áreas estarão fora? Quem determinará a meta? Quem serão os membros do COPOM? Essas são apenas algumas questões que surgem quando se fala em autonomia do canco central. Existem diversos exemplos de bancos centrais autônomos no mundo e esse estudo irá analisar como esses cancos centrais operam, para que futuramente se possa tentar desenhar um arranjo institucional que se adapte as necessidades brasileiras.

A note on policy, the composition of public expenditures and economic growth

In this article we study the growth and welfare effects of fiscal and monetary policies in economies where public investment is part of the productive process we present four different models that share the same technology with public infrastructure as a separate argument of the production function. We show that growth is maximized at positive levels of income tax and inflation. However, unless there are no transfers or public goods in the economy, maximization of growth does not imply welfare maximization we show that the optimal tax rate is greater than the rate that maximizes growth and the optimal rate of money creation is below the growth maximizing rate. With public infrastructure in the production function we no longer obtain superneutrality in the Sidrausky model.

Public debt indexation and denomination, the case of Brazil: a comment

In this work I analyze the model proposed by Goldfajn (2000) to study the choice of the denomination of the public debt. The main purpose of the analysis is pointing out possible reasons why new empirical evidence provided by Bevilaqua, Garcia and Nechio (2004), regarding a more recent time period, Önds a lower empirical support to the model. I also provide a measure of the overestimation of the welfare gains of hedging the debt led by the simpliÖed time frame of the model. Assuming a time-preference parameter of 0.9, for instance, welfare gains associated with a hedge to the debt that reduces to a half a once-for-all 20%-of-GDP shock to government spending run around 1.43% of GDP under the no-tax-smoothing structure of the model. Under a Ramsey allocation, though, welfare gains amount to just around 0.05% of GDP.

Tests of conditional asset pricing models in the brazilian stock market

In this paper, we test a version of the conditional CAPM with respect to a local market portfolio, proxied by the Brazilian stock index during the period 1976-1992. We also test a conditional APT modeI by using the difference between the 3-day rate (Cdb) and the overnight rate as a second factor in addition to the market portfolio in order to capture the large inflation risk present during this period. The conditional CAPM and APT models are estimated by the Generalized Method of Moments (GMM) and tested on a set of size portfolios created from individual securities exchanged on the Brazilian markets. The inclusion of this second factor proves to be important for the appropriate pricing of the portfolios.

Effects of the real plan of the Brazilian banking system

The aim of this paper is to assess the progress of the banking sector before and shortly after the Real Plan. We began by assessing the drop in the inflation revenues (negative real interest rates paid by the excess of demand deposits over total reserve requirements) as a result of the change in inflation from 40% a month for the pre-Real Plan period to a monthly average of 3.65% (IGP-DI), between July 1994 and May 1995. Then, using the financial statement data of a group of 90 banks, we attempt to estimate the net losses due to the inflation drop analyzing the profitability and other parameters of the banking industry. The calculations are made separately for private, state and federal banks. A later analysis on performance using information given to CVM (Securities Exchange Commission) by the six major private banks in the country is also discussed herein.

An overview of some historical brazilian macroeconomic series and some open questions

This paper presents an overview of the Brazilian macroeconomy by analyzing the evolution of some specific time series. The presentation is made through a sequence of graphs. Several remarkable historical points and open questions come up in the data. These include, among others, the drop in output growth as of 1980, the clear shift from investments to government current expenditures which started in the beginning of the 80s, the notable way how money, prices and exchange rate correlate in an environment of permanently high inflation, the historical coexistence of high rates of growth and high rates of inflation, as well as the drastic increase of the velocity of circulation of money between the 70s and the mid-90s. It is also shown that, although net external liabilities have increased substantially in current dollars after the Real Plan, its ratio with respect to exports in 2004 is practically the same as the one existing in 1986; and that residents in Brazil, in average, owed two more months of their final income (GNP) to abroad between 1995-2004 than they did between 1990 and 1994. Variance decompositions show that money has been important to explain prices, but not output (GDP).

A note on growth, welfare and public policy

In this note the growth anti welfare effects of fiscal anti monetary policies are investigated in three economies where public investment is part of the productive process It is shown that growth is maximized at positive levels of income tax and inflation but that there is no direct relationship between government size, productivity and growth or between inflation and growth. However, unless there are no transfers or public goods in the economy, maximization of growth does not imply welfare maximization and the optimal tax rate and government size are greater than those that maximize growth. Money is not superneutral anti the optimal rate of money creation is below the maximizing rate of growth.

The Brazilian social security program:diagnosis and proposal for reform

The Brazilian pay-as-you-go social security program is analyzed in a historical perspective. Its contribution to income inequality, and the role played by the inflation as a balancing variable are discussed. It is shown that budgetary constraints due to the increasing informalization of the labor force can no longer be reconciled with protligate eligibility criteria. A tailor-made proposal for reform is presented as well as a plan for financing the transition from today's system to the proposed one.
