This paper deals with the familiar enterprise succession leaving as a goal to identify, describe and analyze the factors which facilitate and make difficult the process of succession of the familiar enterprise. To this it contextualizes the familiar enterprise in the labor market through its contexts, process and characters. Afterward it treats of the familiar enterprise as an system in its complexity of this segment of the enterprise. It considered the need on studying its origin, evolution and characteristics. Also the ethics and familiar administration. It also, considered the cycle of life, the three-dimensional model of development having as a base the propriety, family and enterprise axes as well as the familiar profissionalization, the main focus reposes in the succession process having as a base its planning the field search reveals it self descriptive, that¿s to say a case study through interview with the proprietors, successors, aggregates and succeeded ones. Finally the management indicators which aim, to contribute to the familiar succession.

o presente trabalho tem por objetivo avaliar o impacto produzido sobre os trabalhadores das organizações através da implantação de sistemas integrados de gestão (ERP) , como instrumento apoiador da flexibilização organizacional. O estudo abrangeu empresas do ramo de serviços que implantaram o sistema ERP da empresa SAP AG, através de questionários e entrevistas realizadas diretamente com os trabalhadores envolvidos. Os principais impactos para os trabalhadores foram: aumento na pressão sobre trabalho, exigência por maior capacitação, redução do nível de supervisão, aumento na qualidade, velocidade e complexidade do trabalho e redução quadro de pessoal. O nível de participação dos trabalhadores foi diversificado mas muito baixo quanto: ao treinamento, ao fluxo de informação ao longo do projeto, à possibilidade de sugerir melhorias e de influir na condução do projeto. Os objetivos planejados com a implantação foram alcançados e os trabalhadores estão satisfeitos com o sistema enquanto novo instrumento de trabalho. A baixa possibilidade de sugerir melhorias ao longo do projeto, aliado com o bom índice de aceitação das sugestões quando elas ocorreram, confirmam a hipótese de que o potencial social das organizações não foi suficientemente considerado inibindo melhorias para as empresas. A redução de pessoal, o baixo nível de participação do trabalhador em passos importantes do projeto e o baixo nível de abertura para sugestões de melhoria apuradas nesse estudo, confirmam a tendência de intensificação do uso da mão-de-obra e do conhecimento do trabalhador em detrimento de sua emancipação como agente ativo e participante da gestão, restringindo assim a efetiva flexibilização organizacional.

Na presente dissertação tem como objetivo avaliar o impacto do programa JUNTOS sobre a taxa de freqüência escolar e sobre o trabalho infantil nas crianças de 6 a 14 anos. Estas duas variáveis foram selecionadas para o seu estudo, pois ao nosso entender estas são as principais variáveis que são influenciadas pelo programa JUNTOS e que tem uma influencia direta sobre o capital humano das crianças e assim sobre a diminuição da pobreza futura. As principais hipóteses derivadas das teorias de capital humano e de transferências de rendas condicionadas foram corroboradas pela nossa avaliação: (1) o programa JUNTOS tem um efeito positivo sobre o incremento da freqüência escolar, (2) o programa JUNTOS é efetivo na redução do trabalho infantil, (3) quando o chefe de família é de sexo feminino, a renda familiar é utilizada em bens e serviços em favor das crianças, e (4) o efeito do programa JUNTOS é maior nas crianças com piores características socioeconômicas (ex: menor renda familiar per capita, chefe de família com poucos anos de estudo, idioma do chefe de família, etc.) Outra conclusão importante da dissertação foi que o programa JUNTOS provoca uma realocação na oferta de trabalho intra familiar.

This doctoral dissertation analyzes two novels by the American novelist Robert Coover as examples of hypertextual writing on the book bound page, as tokens of hyperfiction. The complexity displayed in the novels, John's Wife and The Adventures of Lucky Pierre, integrates the cultural elements that characterize the contemporary condition of capitalism and technologized practices that have fostered a different subjectivity evidenced in hypertextual writing and reading, the posthuman subjectivity. The models that account for the complexity of each novel are drawn from the concept of strange attractors in Chaos Theory and from the concept of rhizome in Nomadology. The transformations the characters undergo in the degree of their corporeality sets the plane on which to discuss turbulence and posthumanity. The notions of dynamic patterns and strange attractors, along with the concept of the Body without Organs and Rhizome are interpreted, leading to the revision of narratology and to analytical categories appropriate to the study of the novels. The reading exercised throughout this dissertation enacts Daniel Punday's corporeal reading. The changes in the characters' degree of materiality are associated with the stages of order, turbulence and chaos in the story, bearing on the constitution of subjectivity within and along the reading process. Coover's inscription of planes of consistency to counter linearity and accommodate hypertextual features to the paper supported narratives describes the characters' trajectory as rhizomatic. The study led to the conclusion that narrative today stands more as a regime in a rhizomatic relation with other regimes in cultural practice than as an exclusively literary form and genre. Besides this, posthuman subjectivity emerges as class identity, holding hypertextual novels as their literary form of choice.

Countries differ in terms of technological capabilities and complexity of production structures. According to that, countries may follow different development strategies: one based on extracting rents from abundant endowments, such as labor or natural resources, and the other focused on creating rents through intangibles, basically innovation and knowledge accumulation. The present article studies international convergence and divergence, linking structural change with trade and growth through a North South Ricardian model. The analysis focuses on the asymmetries between Latin America and mature and catching up economies. Empirical evidence supports that a shift in the composition of the production structure in favor of R&D intensive sectors allows achieving higher rates of growth in the long term and increases the capacity to respond to demand changes. A virtuous export-led growth requires laggard countries to reduce the technological gap with respect to more advanced ones. Hence, abundance of factor endowments requires to be matched with technological capabilities development for countries to converge in the long term.

Brazil has a substantial share – about 60% by some measures - of its employees working without labor registry and 62% of its private sector workers not contributing to social security. Informality is important because its job precaurioness, social desprotection consequences, and it is also very correlated with poverty and other social welfare concepts measured at a family level. 58% of the country population that is found below the indigent line live in families headed by informal workers. The complexity of the informal sector is derived from the multiple relevant dimensions of jobs quality. The basis used for guiding policy interventions depends on which effect of informality one is interested such: as lowering job precaurioness, increasing occupational risks, increasing the degree of protection against adverse shocks, allowing that good oportunities to be taken by the credit provision, improving informal workers families living conditions, implementing afirmative actions, reducing tax evasion etc. This report gauges various aspects of the informal sector activities in Brazil over the last decades. Our artistic constraint are the available sources of information. The final purpose is to help the design of policies aimed to assist those that hold “indecent” jobs

Brazil’s experience shows that the economic and political history of a country is a critical determinant of which labor laws influence wages and employment, and which are not binding. Long periods of high inflation, illiteracy of the workforce, and biases in the design and enforcement of labor legislation bred by the country’s socioeconomic history are all important in determining the reach of labor laws. Defying conventional wisdom, these factors are shown to affect labor market outcomes even in the sector of employment regarded as unregulated. Following accepted practice in Brazil, we distinguish regulated from unregulated employment by determining whether or not the contract has been ratified by the Ministry of Labor, viz., groups of workers with and without signed work booklet. We then examine the degree of adherence to labor laws in the formal and informal sectors, and finds “pressure points” – viz., evidence of the law on minimum wage, work-hours, and payment timing being binding on outcomes – in both the formal and informal sectors of the Brazilian labor market. The findings of the paper imply that in terms of the design of legislation, informality in Brazil is mainly a fiscal, and not a legal phenomenon. But the manner in which these laws have been enforced is also critical determinant of informality in Brazil: poor record-keeping has strengthened the incentives to stay informal that are already built into the design of the main social security programs, and ambiguities in the design of labor legislation combined with slanted enforcement by labor courts have led to workers effectively being accorded the same labor rights whether or not they have ratified contracts. The incentives to stay informal are naturally higher for workers who are assured of protection under labor legislation regardless of the nature of their contract, which only alters their financial relationship with the government. The paper concludes that informality in Brazil will remain high as long as labor laws remain ambiguous and enforced with a clear pro-labor bias, and social security programs lack tight benefitcontribution linkages and strong enforcement mechanisms.

This paper evaluates the long-run effects of economic instability. In particular, we study the impact of idiosyncratic shocks to father’s income on children’s human capital accumulation variables such as school drop-outs, repetition rates and domestic and non-domestic labor. Although, the problem of child labor in Brazil has declined greatly during the last decade, the number of children working is still substantial. The low levels of educational attainment in Brazil are also a main cause for concern. The large rotating panel data set used allows for the estimation of the impacts of changes in occupational and income status of fathers on changes in his child’s time allocation circumstances. The empirical analysis is restricted to families with fathers, mothers and at least one child between 10 and 15 years of age in the main Brazilian metropolitan areas during the 1982-1999 period. We perform logistic regressions controlling for child characteristics (gender, age, if he/she is behind in school for age), parents characteristics (grade attainment and income) and time and location variables. The main variables analyzed are dynamic proxies of impulses and responses, namely: shocks to household head’s income and unemployment status, on the one hand and child’s probability of dropping out of school, of repeating a grade and of start working, on the other. The findings suggest that father’s income has a significant positive correlation with child’s dropping out of school and of repeating a grade. The findings do not suggest a significant relationship between a father’s becoming unemployed and a child entering the non-domestic labor market. However, the results demonstrate a significant positive relationship between a father becoming unemployed and a child beginning to work in domestic labor. There was also a positive correlation between father becoming unemployed and a child dropping out and repeating a grade. Both gender and age were highly significant with boys and older children being more likely to work, drop-out and repeat grades.

This thesis provides three original contributions to the field of Decision Sciences. The first contribution explores the field of heuristics and biases. New variations of the Cognitive Reflection Test (CRT--a test to measure "the ability or disposition to resist reporting the response that first comes to mind"), are provided. The original CRT (S. Frederick [2005] Journal of Economic Perspectives, v. 19:4, pp.24-42) has items in which the response is immediate--and erroneous. It is shown that by merely varying the numerical parameters of the problems, large deviations in response are found. Not only the final results are affected by the proposed variations, but so is processing fluency. It seems that numbers' magnitudes serve as a cue to activate system-2 type reasoning. The second contribution explores Managerial Algorithmics Theory (M. Moldoveanu [2009] Strategic Management Journal, v. 30, pp. 737-763); an ambitious research program that states that managers display cognitive choices with a "preference towards solving problems of low computational complexity". An empirical test of this hypothesis is conducted, with results showing that this premise is not supported. A number of problems are designed with the intent of testing the predictions from managerial algorithmics against the predictions of cognitive psychology. The results demonstrate (once again) that framing effects profoundly affect choice, and (an original insight) that managers are unable to distinguish computational complexity problem classes. The third contribution explores a new approach to a computationally complex problem in marketing: the shelf space allocation problem (M-H Yang [2001] European Journal of Operational Research, v. 131, pp.107--118). A new representation for a genetic algorithm is developed, and computational experiments demonstrate its feasibility as a practical solution method. These studies lie at the interface of psychology and economics (with bounded rationality and the heuristics and biases programme), psychology, strategy, and computational complexity, and heuristics for computationally hard problems in management science.

In most developing countries, job regulations and the justice branch interfere on several aspects of labor contracts. Inspired by this fact, we build a model that explores the role of labor courts in the determination of the di¤erence between formal and informal wages. We show that the presence of active labor courts in an environment where labor relations are subject to asymmetries of information reproduces features documented by the empirical literature. The main implications of our model are tested using Brazilian data.

This paper investigates the impact of working while in school on learning outcomes through the use of a unique micro panel dataset of Brazilian students. The potential endogeneity is addressed through the use of di erence-in-di erence and instrumental variable estimators. A negative e ect of working on learning outcomes in both math and Portuguese is found. The e ects of child work range from 3% to 8% of a standard deviation decline in test score which represents a loss of about a quarter to a half of a year of learning on average. We also explore the minimum legal age to entry in the labor market to induce an exogenous variation in child labor status. The results reinforce the detrimental e ects of child labor on learning. Additionally, it is found that this e ect is likely due to the interference of work with the time kids can devote to school and school work.

For representing an expressive souree of labor absorption, the jobs with informal labor eontraet have been reeeiving a eonsiderable attention among the speeialists in the Brazilian labor rnarket. This paper presents, eoneisely, some stylized faets about this labor rnarket segment, as well as some oftheir most eommon interpretations. We argue that sue h interpretations are, in general, not very integrated and a model trying to make them eompatible is developed. The model ineorporates both segmentation and workers with heterogeneity in qualifieation. The results of the analysis are shown to be eompatible with most of the observed faets.

This paper estimates the elasticity of substitution of an aggregate production function. The estimating equation is derived from the steady state of a neoclassical growth model. The data comes from the PWT in which different countries face different relative prices of the investment good and exhibit different investment-output ratios. Then, using this variation we estimate the elasticity of substitution. The novelty of our approach is that we use dynamic panel data techniques, which allow us to distinguish between the short and the long run elasticity and handle a host of econometric and substantive issues. In particular we accommodate the possibility that different countries have different total factor productivities and other country specific effects and that such effects are correlated with the regressors. We also accommodate the possibility that the regressors are correlated with the error terms and that shocks to regressors are manifested in future periods. Taking all this into account our estimation resuIts suggest that the Iong run eIasticity of substitution is 0.7, which is Iower than the eIasticity that had been used in previous macro-deveIopment exercises. We show that this lower eIasticity reinforces the power of the neoclassical mo deI to expIain income differences across countries as coming from differential distortions.

Economic reform in China has created a small, but fast-growing private sector that has spurred rapid productivity growth. Growth of the private sector is predicated upon continued labor movements away from state-run industries and into private firms. This paper presents a theory of labor market sectoral choice demonstrating that three factors determine private sector labor supply-the difference in wages between the state and private sectors, private sector wage risk and risk aversion. Estimation of the model using survey data provides strong support for the theory. We find that the riskiness of private sector earnings has a greater effect in discouraging workers from taking jobs in private firms than the wage premi um has in attracting workers.
