A relação da motivação para o trabalho com as metas do trabalhador: um estudo de caso em uma operadora de call center

Having as basic purpose, that the work motivational strategies are more efficient when elaborated directly from the worker¿s personal goals and values, the study line of this dissertation searched to identify the worker¿s motivational employee¿s profile from call center industry. The knowledge of this motivational profile makes possible the development of differentiated programs of motivation inside the organization, aiming to attend goals of diverse groups of workers. In order to achieve the considered objective, the present dissertation analyzed one of the biggest companies in call center¿s inside Brazilian market, the BrasilCenter Communications Ltda. In such a way, in the first stage of the study, a bibliographical research was carried out, with the objective to collect contributions from diverse authors on the motivation subject, and also a modern theory of values was presented, verified empirically in more than 60 countries, which identifies the people¿s motivational structure. Having as base the results of these studies, the worker¿s concept profile motivational and argued its way of evaluation in the organizations it was boarded. In the second stage, a field research was carried out, with the application of the Inventory of Values of Schwartz theory (IVS), in order to identify the employee¿s motivational profile crowded in the Center of Attendance and Services (call center) company, located in Juiz de Fora city. The analysis of the results from the field research, based on the bibliographical data, identified that the values prioritized for the call center¿s employees are the ones that serves the collective and mixing goals. This motivational profile offers some perspectives of employee¿s valuation that correspond to their goals and interests. The displayed results point respect to the centrality of the types of values benevolence, conformity, security and universalism among the participants in the sample. As the accented was more among the employees it was the search of collective results it, is concluded that the more appropriate valuation strategies are those related to the tolerance for the ideas and opinion of the others, to harmonic a organizational enviroment, the concern with the quality of life at work and the social aspects of the work.

Optimal auction with a general distribution: virtual valuation without densities

We characterize the optimal auction in an independent private values framework for a completely general distribution of valuations. We do this introducing a new concept: the generalized virtual valuation. To show the wider applicability of this concept we present two examples showing how to extend the classical models of Mussa and Rosen and Baron and Myerson for arbitrary distributions

Estudo experimental sobre a precisão e validade dos escores introversão-extroversão de uma adaptação brasileira do Maudsley Personality Inventory de H.J. Eysenck

O propósito dos trabalhos experimentais expostos na presente dissertação foi o de estudar a versão brasileira do Maudaley Personality Inventory. de Eysench. no que diz respeito à sua dimensão bipolar introversão-extroversão. A adaptação brasileira (devida à Professora Riva Bauzer) foi aplicada por duas vezes a 70 estudantes, de quatro turmas do Colégio Batista Shepard, que são nossos alunos de psicologia. Paralelamente a esta aplicação, foi aplicado por duas vezes sucessivas, aos mesmos alunos, um questionário por nós organizado. Nele era pedida a cada um uma avaliação subjetiva do grau de introversão-extroversão dos respectivos colegas de classe. Desse modo tivemos a possibilidade de avaliar: a) o coeficiente de precisão do questionário; b) o coeficiente de precisão do Maudeley Personality Inventory; c) o coeficiente de validade do Maudaley Persona lity Inventory, tomando o questionário como critério de validação. Entretanto, nao terminaram ai nossos trabalhos. Por meio do coeficiente de correlação bisserial, foi estimado o poder discriminante de cada uma das questões do Maudsley Personality Inventory, assim como seu grau de "popularidade". Esta é uma denominação por nós atribuida à porcentagem de sujeitos que assinalaram a questão no sentido de extroversão. Estes elementos abrem caminho para a realização de pesquisas ulteriores com a finalidade de aperfeiçoar a versão brasileira do Maudsley Personality Inventory.

Ownership, control and corporate valuation of Brazilian companies

We study the direct and indirect ownership structure of Brazilian corporations and their market value and risk by the end of 1996 and 1998. Ownership is quite concentrated with most companies being controlled by a single direct shareholder. We find evidence that indirect control structures may be used to concentrate control even more rather than to keep control of the company with a smaller share of total capital. The greater the concentration of voting rights then less the value of the fmn should be due to potential expropriation ofrninority shareholders. We fmd evidence that when there is a majority shareholder and when indirect ownership structures are used without the loss of control, corporate valuations are greater when control is dilluted through the indirect ownership structure. This evidence is consistent with the existence of private benefits of control that can be translated as potential minority shareholder expropriation.

Valuation equilibrium with crubs

This paper considers model worlds in which there are a continuum of individuaIs who form finite sized associations to undertake joint activities. We show that if there are a finite set of types and the commodity space contains lotteries, then the c1assicaI equilibrium results on convex economies can be reinterpreted to apply. Furthermore, in this lottery economy deterministic aIlocations (that is, degenerate lotteries) are generally not Pareto optimal, nor are they equilibria. In the interests of making the model seem more "natural," we show that the set of equilibria in a decentraIization in which individuaIs first gamble over vaIue transfers and then trade commodities in a deterministic competitive market economy are equivalent to those of our competi tive economy with a lottery commodity space.

Valuation and performance of firms in complex ownership structures : an application to Korean chaebols

We propose several new metrics to describe the complex ownership structure of business groups, and provide simple formulas and algorithms to compute these metrics. We use these measures to describe in detail the ownership structure of Korean chaebols in the period of 2003 to 2004. In addition, we validate the usefulness of our new metrics by showing empirically that they are important for understanding the valuation and performance of group firms. In particular, we show evidence that firms that are central to the control structure of the chaebol (central firms), firms in cross-shareholdings, and firms that are placed at the bottom of the group (i.e., with lower ultimate ownership) have lower profitability than other group firms. The valuation results suggest that central firms and firms in cross-shareholding loops have lower valuations than other public Chaebol firms. The lower valuation of these firms is not explained by variation in measures of ownership concentration and separation between ownership and control.
