This paper employs mechanism design to study the effects of imperfect legal enforcement on optimal scale of projects, borrowing interest rates and the probability of default. The analysis departs from an environment that combines asymmetric information about cash flows and limited commitment by borrowers. Incentive for repayment comes from the possibility of liquidation of projects by a court, but courts are costly and may fail to liquidate. The value of liquidated assets can be used as collateral: it is transferred to the lender when courts liquidate. Examples reveal that costly use of courts may be optimal, which contrasts with results from most limited commitment models, where punishments are just threats, never applied in optimal arrangements. I show that when voluntary liquidation is allowed, both asymmetric information and uncertainty about courts are necessary conditions for legal punishments ever to be applied. Numerical solutions for several parametric specifications are presented, allowing for heterogeneity on initial wealth and variability of project returns. In all such solutions, wealthier individuals borrow with lower interest rates and run higher scale enterprises, which is consistent with stylized facts. The reliability of courts has a consistently positive effect on the scale of projects. However its effect on interest rates is subtler and depends essentially on the degree of curvature of the production function. Numerical results also show that the possibility of collateral seizing allows comovements of the interest rates and the probability of repayment.

This dissertation aims at examining empirical evidences obtained in the light of taxonomies and strategies for measuring firms technological capabilities and innovation in the context of developing countries, motivated by the fact that debates and studies directed to innovation has been intensified, for the last thirty years, by the recognition of its vital and growing importance to the technological, economic, competitive and industrial development of firms and countries. Two main tendencies can be identified on this debate. At one side, it¿s the literature related to the developed countries logic, whose companies are, in majority, positioned at the technological frontier, characterized by the domain of innovative advanced capabilities, directed to its sustaining, deepening and renewal. At the other side, there are the perspectives directed to the developing countries reality, where there is a prevalence of companies with deficiency of resources, still in process of accumulating basic and intermediate technological capabilities, with characteristics and technological development trajectories distinct or even reverse from those of developing countries. From this last tradition of studies, the measuring approaches based in C&T indicators and in types and levels of technological capabilities stand out. The first offers a macro level, aggregated perspective, through the analysis of a representative sample of firms, seeking to the generation of internationally comparable data, without addressing the intraorganizational specificities and nuances of the paths of technological accumulation developed by the firms, using, mostly, R&D statistics, patents, individual qualifications, indicators that carry their own limitations. On the other hand, studies that examine types and levels of technological capabilities are scarce, usually directed to a small sample of firms and/or industrial sectors. Therefore, in the light of the focus and potentialities of each of the perspectives, this scenario exposes a lack of studies that examine, in a parallel and complementary way, both types of strategies, seeking to offer more realistic, consistent and concrete information about the technological reality of developing countries. In order to close this gap, this dissertation examines (i) strategies of innovation measurement in the contexts of developing countries based on traditional approaches and C&T indicators, represented by four innovation surveys - ECIB, PINTEC, PAEP and EAI, and, (ii) from the perspective of technological capabilities as an intrinsic resource of the firm, the development of which occurs in a cumulative way and based on learning, presents and extracts generalizations of empirical applications of a metric that identifies types and levels of technological capabilities, through a dynamic and intra-firm perspective. The exam of the empirical evidences of the two approaches showed what each one of the metrics are capable to offer and the way they can contribute to the generation of information that reflect the technological development of specific industrial sectors in developing countries. In spite of the fact that the focus, objective, perspective, inclusion, scope and lens used are substantially distinct, generating, on a side, an aggregated view, and of other, an intra-sector, intra-organizational and specific view, the results suggest that the use of one doesn't implicate discarding or abdicating the other. On the contrary, using both in a complementary way means the generation of more complete, rich and relevant evidences and analysis that offer a realistic notion of the industrial development and contribute in a more direct way to the design of corporate strategies and government policies, including those directed to the macro level aspects just as those more specific and focused, designed to increment and foment firms in-house innovative efforts.

Nos últimos dez anos a gestão do conhecimento tem crescido em importância tanto no meio acadêmico como empresarial. Ainda que alguns permaneçam céticos, sua relevância para a competitividade das organizações tem se tornado cada vez mais um ponto de concordância nos dois ambientes, como uma resposta aos desafios sociais e econômicos impostos. Estes desafios impulsionam a gestão do conhecimento vista como uma disciplina interdisciplinar focada nos agentes e no seu ambiente, e no processo de criação, mapeamento e transferência do conhecimento, com o objetivo final de gerar vantagens competitivas sustentáveis. Apesar de muitos estudos específicos, ainda são poucos os trabalhos que buscam avaliar a adoção da gestão do conhecimento como abordagem ampla, quase como um novo paradigma gerencial adaptado à nova realidade econômica vigente, assim como são poucos os estudos que buscam avaliar o impacto na criação de valor de estratégias focadas no conhecimento. Este trabalho visa preencher essa lacuna, avaliando a adoção de práticas, conceitos e atitudes vinculadas à gestão do conhecimento em empresas de grande e pequeno porte criadoras de valor, através de estudos de caso. Para isso, o trabalho partiu de uma ampla revisão da literatura em torno do tema para definir um conjunto de práticas associadas ao conceito de gestão do conhecimento, dividido em seis dimensões: estratégia, estrutura, tecnologia da informação, cultura e pessoas, sistemas de suporte e processos. A partir deste levantamento, instrumentos distintos – questionário e roteiro de entrevista - foram elaborados para estudar as grandes e pequenas empresas. A pesquisa de campo só foi realizada após a validação do instrumento por especialistas na área, que avaliaram cada item com relação a sua total, parcial ou marginal associação ao conceito de gestão do conhecimento. Os resultados mostram que, independente do tamanho, as empresas criadoras de valor adotam muitas das práticas associadas a gestão do conhecimento em cinco das seis dimensões estudadas. Além destes indícios, o trabalho também contribui ao deixar um rol de mais de duzentos e trinta itens validados com relação ao conceito de gestão do conhecimento, que podem ser testados e aperfeiçoados.

Esta dissertação traz uma análise do atual sistema de mensuração de desempenho do Poder Judiciário brasileiro, mais especificamente no tocante ao processo que visa à disseminação e a incorporação da prática da mensuração na cultura organizacional das unidades judiciárias de todo o país. Após análise bibliográfica e documental, é tomada a experiência de mensuração do desempenho judiciário dos países europeus como referência comparativa ao sistema brasileiro, bem como são consideradas percepções de gestores deste sistema com relação a seus entendimentos acerca da gestão e mensuração de desempenho no Judiciário, aos esforços políticos e administrativos adotados, ao possível futuro do sistema, dentre outras. Uma vez que esta representa uma primeira experiência no sentido da adoção da mensuração de desempenho judiciário enquanto política nacional, o estudo também discute a natureza de problemas estruturais e organizacionais a serem trabalhados no Judiciário brasileiro visando à prática da mensuração, além da necessidade de uma padronização em processos administrativos ligados a esta prática nas heterogêneas organizações judiciárias brasileiras.

We introduce human capital accumulation, in the form of learning by doing, in a life cycle model of career concerns and analyze how human capital acquisition a ects implicit incentives for performance. We show that standard results from the career concerns literature can be reversed in the presence of human capital accumulation. Namely, implicit incentives need not decrease over time and may decrease with the degree of uncertainty about an individual's talent. Furthermore, increasing the pre-cision of output measurement can weaken rather than strengthen implicit incentives. Overall, our results contribute to shed new light on the ability of markets to discipline moral hazard in the absence of explicit contracts linking pay to performance.

O telefone celular teve uma grande evolução nos últimos anos, o que antes era utilizado exclusivamente para transmissão de voz, hoje tem características avançadíssimas incluindo várias evoluções tecnológicas. Dentro deste aspecto, a inovação que o LTE (Long Term Evolution) vem demonstrando em suas características realmente se destacam em relação as tecnologias que a antecederam e representa grande evolução se comparada com as outras. Foi desenvolvida no âmbito do projeto 3GPP e (3rd Generation Partners Project) promovido pelo Instituto Europeu de Normalização na área de Telecomunicações ETSI (European Telecommunications Standard Institute). As operadoras que demonstram interesse em disponibilizar esta tecnologia buscam introduzir a flexibilidade do LTE para ir ao encontro dos objetivos de suas redes existentes, espectro e negócios para banda larga móvel e serviços multimídia. O LTE promete taxas de download de 326,4Mbps, taxas de upload de 86,4Mbps, RTT ( ROUND TRIP TIME ) menos de 10 mile segundos e raio das células podendo atingir até 100km.

This work, developed within the Master's Degree Program in Public Administration and Government of Eaesp-FGV, consists of an exploratory study on performance measurement in the public sector. It is focused on the identification of complexity elements embedded in the implementation of public policies, to which the goals and targets of a target-oriented system relate, and especially on the implementation of this system as a management tool itself, from the case study of the then ongoing "Programa de Metas da Cidade de São Paulo 2013-2016". All information was obtained from municipal managers, in Government Departments responsible for strategic support activities to the implementation of the system, and sectoral Government Departments whose scope also included crosscutting actions, through interviews conducted from a starting question, and then followed by the free talk of the respondents. Through discourse analysis, an assortment of information was conducted, concerning to: 1) the impacts on management, articulation, and governance of the use of performance measurement and result-oriented management; 2) the flow and publicity of information on performance, produced within the monitoring process of this given target-oriented system, and also concerning the use given to this information; 3) the recording and register of experiences and learning related to the Programa de Metas, and its potential to result as a legacy for the public administrative structure of the City of São Paulo. Assuming that the stories managers tell, in this field of Applied Social Sciences, are as valid as Science or the theoretical constructs on the subject, all information gathered from the point of view of the interviewed public officials was segmented and problematized under the light of the literature on performance measurement. The main objective of this research is to contribute to the creation of parameters for qualitative analysis of the information generated in the implementation of a target-oriented system in Public Management at the local level. It is, from then on, expected that these parameters may help managers and researchers on the monitoring and evaluation of performance of a given government, by favoring the translation of merely arithmetic data on percentage of fulfillment of specific commitments, into eloquent elements more enabled to express the evolution of a mandate. Keywords: result-oriented system, Programa de Metas, management for results, performance measurement, government planning, public policy evaluation, monitoring, implementation, transparency, information legacy.
