Análise dos aspectos envolvidos na condução de contratos de terceirização de tecnologia da informação

Terceirização de Serviços de Tecnologia da Informação (TI) é uma prática crescente entre organizações de diversos portes e setores, onde uma relação entre contratante e contratado usualmente regida por contratos. Contratos são dispositivos destinados a regular obrigações e direitos entre as partes. Em função da impossibilidade das partes preverem todas as contingências futuras e também devido à imprecisão da linguagem escrita, contratos são usualmente reconhecidos em Economia como sendo fundamentalmente incompletos. Disso se origina a possibilidade de classificar contratos como predominantemente formais, aqueles cuja estrutura escrita apresenta mecanismos de completude suficiente para conduzir o relacionamento entre as partes, e predominantemente relacionais, aqueles cuja estrutura formal é insuficiente para coordenar o relacionamento, e que demandam mecanismos adicionais de comunicação e interação para que o relacionamento entre as partes ocorra de adequadamente em torno do objeto contratado. Dentre os mecanismos usados em contratos formais para sinalizar às partes os comportamentos desejados, inclui-se a estrutura de incentivos. Pouco se estudou sobre o efeito que a combinação de estruturas de incentivos e mecanismos relacionais tem sobre o andamento dos contratos. Este estudo analisa os efeitos de mecanismos formais de estruturas de incentivos e os mecanismos relacionais sobre o andamento do contrato, usando como contexto o cenário de contratações de serviços de terceirização de Tecnologia da Informação (TI). Como resultados dos três capítulos principais deste estudo, configurados no formato de artigos acadêmicos, são apresentados altos poderes explicativos das interações entre estruturas de incentivos, governança relacional, comportamento do contratado e expectativa de sucesso dos contratos. Da mesma forma, antecedentes e resultantes são analisados e discutidos. Do ponto de vista da contribuição para a prática gerencial, o trabalho como um todo contribui para melhorar decisões de contratação de serviços de TI, formulação de contratos mais efetivos, e apoio na escolha dos mecanismos de contratação mais adequados ao contexto do contratante.

Discrete public goods with incomplete information

We analyze simultaneous discrete public good games wi.th incomplete information and continuous contributions. To use the terminology of Admati and Perry (1991). we consider comribution and subscription games. In the former. comrioutions are :1ot rcfunded if the project is not completed. while in thp. iatter they are. For the special case whp.re provision by a single player is possible we show the existence of an equilibrium in Doth cootribution and subscription games where a player decides to provide the good by himself. For the case where is not feasible for a single player to provide the good by himself, we show that any equilibriwn of both games is inefficient. WE also provide a sufficient condition for "contributing zero" to be the unique equilibrium of the contribution garoe with n players and characterize e

Discrete public goods with incomplete information

We analyze simultaneous discrete public good games with incomplete information and continuous contributions. To use the tenninology of Admati and Perry (1991), we consider contribution and subscription games. In the former, contributions are not refunded ifthe project is not completed, while in the latter they are. For the special case where provision by a single player is possible we show the existence of an equihbrium in both contnbution and subscription games where a player decides to provide the good by himself. For the case where is not feasible for a single player to provide the good by himself: we show that there exist equilibria of the subscription game where each participant pays the same amount. Moreover, using the technical apparatus from Myerson (1981) we show that neither the subscription nor the contribution games admit ex-post eÁ cient equibbria. hl addition. we provide a suÁ cient condition for êontributing zero 'to be the unique equihbrium of the contnbution game with n players.

Incomplete contracts and the problem of social harm

We construct a model in which a first mover decides on its location before it knows the identity of the second mover; joint location results in a negative extemality. Contracts are inherently incomplete since the first mover's initial decision cannot be specified. We analyze several kinds of rights, including damages, injunctions, and rights to exclude (arising from covenants or land ownership). There are cases in which allocating any of these basic rights to the first mover-i.e., first-party rights-is dominated by second-party rights, and cases in which the reverse is true. A Coasian result (efficiency regardless of the rights allocation) only holds under a limited set of conditions. As corollaries of a theorem ranking the basic rights regimes, a number of results emerge contradicting conventional wisdom, including the relative inefficiency of concentrated land ownership and the relevance of the generator's identity. We conclude with a mechanism and a new rights regime that each yield the first best in all cases.

Optimal exchange rate policy, optimal incomplete taxation and business cycles

Implementation and collapse of exchange rate pegging schemes are recur- rent events. A currency crisis (pegging) is usually followed by an economic downturn (boom). This essay explains why a benevolent government should pursue Þscal and monetary policies that lead to those recurrent currency crises and subsequent periods of pegging. It is shown that the optimal policy induces a competitive equilibrium that displays a boom in periods of below average de- valuation and a recession in periods of above average devaluation. A currency crisis (pegging) can be understood as an optimal policy answer to a recession (boom).

Macroeconomic announcements, price discovery, and order flow efects in the stock market: evidence from incomplete data and multiple financial markets

This paper investigates heterogeneity in the market assessment of public macro- economic announcements by exploring (jointly) two main mechanisms through which macroeconomic news might enter stock prices: instantaneous fundamental news im- pacts consistent with the asset pricing view of symmetric information, and permanent order ow e¤ects consistent with a microstructure view of asymmetric information related to heterogeneous interpretation of public news. Theoretical motivation and empirical evidence for the operation of both mechanisms are presented. Signi cant in- stantaneous news impacts are detected for news related to real activity (including em- ployment), investment, in ation, and monetary policy; however, signi cant order ow e¤ects are also observed on employment announcement days. A multi-market analysis suggests that these asymmetric information e¤ects come from uncertainty about long term interest rates due to heterogeneous assessments of future Fed responses to em- ployment shocks.

Endogenous borrowing constraints and default when markets are incomplete

Incomplete markets and non-default borrowing constraints increase the volatility of pricing kernels and are helpful when addressing assetpricing puzzles. However, ruling out default when markets are in complete is suboptimal. This paper endogenizes borrowing constraints as an intertemporal incentive structure to default. It modeIs an infinitehorizon economy, where agents are allowed not to pay their liabilities and face borrowing constraints that depend on the individual history of default. Those constraints trade off the economy's risk-sharing possibilities and incentives to prevent default. The equilibrium presents stationary properties, such as an invariant distribution for the assets' solvency rate.

Intrinsic and relational perspectives of relationship value: an integrated framework in buyer-supplier relationships

O relacionamento entre firmas vem sendo estudado como um fator que amplia os limites do valor criado pelas firmas individualmente, por meio da construção conjunta de benefícios que não poderia ocorrer caso o relacionamento não se estabelecesse. O valor total criado no nível da díade, que é capturado pelas partes, é o valor do relacionamento. Os benefícios obtidos transcendem as características financeiras da transação, podendo converter-se em outros aspectos da relação entre as firmas, tais como capacitação técnica, oferta de serviços, capacidade de inovação e reputação. Os recursos compartilhados e trocados entre as partes são fontes de criação de valor no relacionamento, mas originam-se de duas perspectivas diferentes. Eles podem pertencer previamente a uma delas, compondo um valor que é intrínseco, ou desenvolverem-se ao longo do relacionamento em si, resultando numa parcela de valor relacional. Neste contexto, este estudo propõe-se a investigar as diferentes características das partes que são fonte de criação de valor em um relacionamento, bem como analisar os aspectos que influenciam sua captura pelas partes. O estudo envolveu três etapas. A primeira, de cunho teórico, visou a explorar as dimensões do valor do relacionamento, no que se refere à sua definição e suas fontes. As duas etapas seguintes objetivaram testar empiricamente o efeito das fontes do valor do relacionamento na criação e captura de valor, por meio de uma survey transversal e um estudo de casos múltiplos. A perspectiva teórica que permeia o estudo é a Visão Baseada em Recursos, uma vez que ela pressupõe que os recursos das firmas produzem valor econômico que transcende os limites delas e é capturado por seus clientes e fornecedores. A abordagem ontológica é a do realismo crítico, a qual permite um melhor entendimento dos acontecimentos empiricamente observados. Os resultados contribuem para um melhor entendimento teórico sobre valor do relacionamento, uma vez que os construtos de valor intrínseco e valor relacional integram diferentes fontes de benefícios que podem advir de relacionamentos. A relação entre esses construtos e sua influência individual na captura de valor também trazem uma contribuição teórica ao estudo de relacionamentos comprador-fornecedor. As principais contribuições gerenciais dizem respeito ao fato de que é possível capturar valor mesmo que o relacionamento não seja colaborativo. Adicionalmente, os resultados enfatizam que as empresas deveriam explorar mais como fazer para extrair mais benefícios da outra parte e do relacionamento em si, em especial de fontes não-financeiras.

Relational value creation and appropriation in buyer supplier relationships

his paper bridges the gap between the buyer-supplier literature and the definition of competitive advantage as value creation found in the strategic management literature. This study proposes and tests an integrative definition of the relational value that is created and appropriated in a dyad

Relational resources: do they create value for both buyer and suppliers?

The study tested the relationship between relational resources and value creation and appropriation. A survey with suppliers and buyers provided evidence that interorganizational fit and knowledge sharing have impact on the relational benefit and the share captured by each organization, but also indicated that each echelon has a different perception

Qualidade de vida em gestantes no contexto na Estratégia Saúde da Família

The pregnancy as a process in woman's life requires several biological, psychological, relational and socio-cultural changes for the preparation for motherhood. By modifying its capacity and, at the expense of these factors, it is observed that the physical, social and emotional problems experienced by women during pregnancy can affect their quality of life, especially related to health. It had as objectives of this research verifying the quality of life of women in the context of the Family Health Strategy in a municipality in Paraíba, in order to characterize the sociodemographic aspects, lifestyle habits, and obstetric care of pregnant women and to characterize the fields of quality of life of pregnant women according to the WHOQOL-bref. This is a descriptive exploratory study with cross-sectional and quantitative approach. The population consisted of 120 pregnant women in primary care in the municipality of Sousa-PB. Data collection occurred over a period of two months by the own master's degree student and two nursing students in applying a standard form about sociodemographic characteristics, and obstetric care and the WHOQOL-bref instrument. The data collected were organized into an electronic database of the Microsoft Excel application, coded, tabulated and presented in tables, charts and figures with their respective percentage distributions. Of the surveyed, the predominant were age group of 20 to 25 years, Catholic religion, with a steady partner, low education, no employment, wage income of 01 minimum wage. As for the data and obstetric care, almost all had never aborted and reported to the care received as excellent. The most frequent complaints were back pain and in lower abdomen. Regarding quality of life according to the WHOQOL-bref, dissatisfactions that predominated in the areas were in the physical pain and discomfort, sleep, rest, energy and fatigue. In the psychological domain, body image and appearance, memory, concentration and negative feelings. In the field of social relationships, sexual activity and the environment domain, the greatest dissatisfaction with facets scored: financial resources, leisure opportunities and transport. It is concluded that the quality of life of the users interviewed were deemed unsatisfactory for these facets, indicating that assistance to this target audience should be done comprehensively and holistically, in order to accommodate the affected facets to improve the quality of life pregnant women attended in primary care
