Ce mémoire n’a pas la prétention d’aborder la totalité des combats menés par ces deux personnalités, Simone de Beauvoir et Elisabeth Badinter, pour la libération des femmes. Cependant, il permet de mettre en évidence, voire en parallèles les actions essentielles de deux femmes de générations différentes. Avec une même sensibilité et une pugnacité sans faille malgré les difficultés et critiques rencontrées, elles ont permis à l’ensemble des hommes et surtout des femmes de prendre conscience des inégalités à combattre pour un meilleur « vivre ensemble ».

Millions of unconscious calculations are made daily by pedestrians walking through the Colby College campus. I used ArcGIS to make a predictive spatial model that chose paths similar to those that are actually used by people on a regular basis. To make a viable model of how most travelers choose their way, I considered both the distance required and the type of traveling surface. I used an iterative process to develop a scheme for weighting travel costs which resulted in accurate least-cost paths to be predicted by ArcMap. The accuracy was confirmed when the calculated routes were compared to satellite photography and were found to overlap well-worn “shortcuts” taken between the paved paths throughout campus.

The calls urging colleges and universities to improve their productivity are coming thick and fast in Brazil. Many studies are suggesting evaluation systems and external criteria to control universities production in qualitative terms. Since universities and colleges are not profit-oriented organizations (considering just the fair and serious researching and teaching organizations, of course) the traditional microeconomics and administrative variables used to measure efficiency do not have any direct function. In this sense, It could be created a as if market control system to evaluate universities and colleges production. The budget and the allocation resources mechanism inside it can be used as an incentive instrument to improve quality and productivity. It will be the main issue of this paper.

A dissertação tem como objetivo analisar dois aspectos do processo de bookbuilding nas emissões de debêntures no mercado brasileiro. O primeiro aspecto é verificar se o underwriter utiliza, a exemplo do que ocorre no Initial Public Offering (IPO) de ações, o poder discricionário nas alocações das debêntures entre os investidores. O segundo consiste em encontrar as características, tanto do emissor quanto do investidor, que influenciam na eficiência do bidder no processo de bookbuilding. Para realizar os testes empíricos foi utilizada uma base de dados composta por 40 books1 (totalizando 727 bids) fornecidos por um banco de investimento.Verifica-se que o underwriter não beneficia nenhum investidor na alocação final das debêntures. Essa afirmação fica evidenciada quando se calcula a diferença entre alocação final (efetivamente recebida pelo investidor) e alocação teórica (estimada com base no método pro-rata) para os 27 books (totalizando 557 bids) que apresentam demanda superior a oferta. A diferença é nula para 96.6% da amostra, sendo que das 19 observações não nulas, 15 possuem diferença absoluta de uma debênture entre a alocação teórica e a final, resultado explicado em função do arredondamento das alocações.Contrariando a teoria de leilão de titulos públicos, onde autores, como Scott and Wolf (1979), defendem que os investidores devem utilizar o step bid como estratégia ótima de bid, este trabalho verificou que no caso de bookbuilding de debêntures no mercado brasileiro, os investidores usuários de step bid posssuem menos chances de ter seu bid atendido plenamente pelo underwriter. Quando o investidor é um gestor de recursos de terceiros (asset management), aumenta-se a possibilidade de ter sua demanda atendida. O maior sucesso do asset management no bookbuilding deve-se às peculiaridades do mercado brasileiro: (i) somente investidores locais participam dos bookbuilding, já que investidores estrangeiros possuem preferência e incentivos por títulos públicos; (ii) gestores de recursos de terceiros representam 75% da demanda por debêntures; (iii) o mercado de gestão de recursos é concentrado: os 5 maiores gestores concentram 60% da indústria. Com isso os gestores de recursos podem desenvolver uma expertise própria, já que são os principais demandadores e frequentemente participam dos bookbuilding. As características do emissor também influenciam no desempenho dos bidders: as debêntures de baixo e médio risco aumentam a possibilidade do bidder ter seu pedido atendido na íntegra. Além disso, como era esperado, quanto maior for a demanda do título, mais dificil é para o investor conseguir a quantidade desejável.

This article investigates the level of delegation in franchise chains, distinguishing the two most relevant franchising models: Business Format Franchising and Learning Network Franchising. The two models basically differ on the level of real authority (effective control over decisions) exercised by the franchisors. Differences in business features, such as the required standardization, monitoring costs and consumer sensitivity to variations in product attributes (consumer measurement costs), explain the adoption of the different models of franchising. These variables affect the trade-off between the risk of brand name loss and the gains in knowledge sharing and learning within the network. The higher the need for standardization, the higher is the risk of brand name loss, and, consequently, the more likely the franchisor will adopt an organizational design that confers more control over franchisees’ decisions, such as business format franchising. This paper presents two case studies with Brazilian food franchise chains that illustrate the main argument and suggest additional propositions. Moreover, an empirical analysis of 223 franchise chains provides additional support to the hypothesis of a negative the effect of required standardization on the level of delegation.

We develop a model to study shelf space allocation in retail. Retailers compete for consumers not only choosing prices but also by the space allocated to each product on shelves. Our approach depart from the existing literature on shelf allocation, as we model the problem of price setting and shelf allocation in an oligopolistic retail market. We present a simple model of retail competition in which prices are dispersed in the crosssection of stores but shelf allocation is not.

We study the problem of centralized allocation of indivisible objects in multiple markets. We show that the set of allocation rules that are group strategy-proof and Pareto-efficient are sequential dictatorships. Therefore, the solution of the joint al-location in multiple markets is significantly narrower than in the single-market case. Our result also applies to dynamic allocation problems. Finally, we provide conditions under which the solution of the single-market allocation coincides with the multiple-market case, and we apply this result to the study of the school choice problem with sibling priorities.
