Apport de la théorie des options à la valorisation du stock d'invendus by Hayet Irzil(
)
2 editions published in 2015 in French and held by 3 WorldCat member libraries worldwide
Since there is not a firm without a stock of unsold goods, the study of this phenomenon is an issue of great importance. Indeed, firms face the stock of unsold goods that they want to clear at the end of the market period. The latter has an impact on not only on the firm's production process, but also on the economy growth. In this context, how to value the stock of unsold goods and when should the firm clears it ? This doctoral work aims to answer to this fundamental question from the standpoint of economics. For this purpose, we must first determineat which price a firm can clear its stock of unsold goods and then determine when it should have recourse to sellingoff market or clearance sales ? The first part of this thesis is dedicated to a review of the literature, both related to management and marketing science, but also to economics. The second part focuses on an original model of unsold goods' stock valuation which is adapted to the microeconomic hedging methods used in finance (including options where the demand is uncertain). Results show that it is possible to provide a hedge against the risk of a stockof unsold goods. On the one hand, the theory is adapted to the case of supply and on the other hand, it fits the case of a stock of unsold goods. From the theoretical point of view, the results of numerical simulations illustrate the way this method works in practice for different cases. The third part is more general since it introduces two intertemporal original models under the monopolistic market structure.There are two types of consumers, depending on the degree of their sensitiveness to the display of goods (those who are sensitive versus those who are not). Consumers who are relatively strongly sensitive to the display of goods choose to buy apart from it. Furthermore, the monopoly chooses both the price and the quantityof displayed goods in order to maximize its profit. Under certain or uncertain demand,it always emerges a stock of unsold goods. The monopoly can sell the stockof unsold goods, either directly to consumers who are insensitive to the display ofgoods, or to the sellingoff firm. Endogenous sellingoff market is then studied

Accumulation des biens, croissance et monnaie by
JeanMarie Cayemitte(
)
1 edition published in 2014 in French and held by 2 WorldCat member libraries worldwide
Cette thèse construit un modèle théorique qui renouvelle l'approche traditionnelle de l'équilibre du marché. En introduisant dans le paradigme néoclassique le principe de préférence pour la quantité, il génère de façon optimale des stocks dans un marché concurrentiel. Les résultats sont très importants, car ils expliquent à la fois l'émergence des invendus et l'existence de cycles économiques. En outre, il étudie le comportement optimal du monopole dont la puissance de marché dépend non seulement de la quantité de biens étalés, mais aussi de celle de biens achetés. Contrairement à l'hypothèse traditionnelle selon laquelle le monopoleur choisit le prix ou la quantité qui maximise son profit, il attire, via un indice de Lerner généralisé la demande à la fois par le prix et la quantité de biens exposés. Quelle que soit la structure du marché, le phénomène d'accumulation des stocks de biens apparaît dans l'économie. De plus, il a l'avantage d'expliquer explicitement les achats impulsifs non encore traités par la théorie économique. Pour vérifier la robustesse des résultats du modèle théorique, ils sont testés sur des données américaines. En raison de leur nonlinéarité, la méthode de GaussNewton est appropriée pour analyser l'impact de la préférence pour la quantité sur la production et l'accumulation de biens, et par conséquent sur les prévisions de PIB. Enfin, cette thèse construit un modèle à générations imbriquées à deux pays qui étend l'équilibre dynamique à un gammaéquilibre dynamique sans friction. Sur la base de la contrainte de détention préalable d'encaisse, il ressort les conditions de suraccumulation du capital et les conséquences de la mobilité du capital sur le bienêtre dans un contexte d'accumulation du stock d'invendus

Développements récents en analyse multivoque : prédérivées et optimisation multivoque by
Yvesner Marcelin(
)
2 editions published in 2016 in French and held by 2 WorldCat member libraries worldwide
This work is devoted to the study of prederivatives of setvalued maps and the theory of optimization. First, we establish results regarding the existence of several kinds of prederivatives for some classes setvalued maps. Specially for setvalued maps enjoying convexity properties. Subsequently, we apply our results in the framework of set optimization by establishing both necessary and sufficient optimality conditions, involving such prederivatives, for set optimization problems. Under convexity assumptions, we prove some natural results fitting the paradigm of minimizers in convex optimization. Then, we apply some of our theoretical results to a model of welfare economics by establishing in particular an equivalence between the weak Pareto optimal allocations of the model and the weak minimizes of a set optimization problem associated. Taking adventadge of several generalized interiority notions existing in the literature, we discuss in a unified way corresponding notions of relaxed minimizers In order to establish stability results, we introduce a topology on vector ordered spaces from which we derive a concept of convergence that we use to define two concepts of variational convergence that allow us to study both the upper and the lower stability of sets of relaxed minimizers we consider

Utilisation de l'élargissement d'opérateurs maximaux monotones pour la résolution d'inclusions variationnelles by
Ludovic Nagesseur(

1 edition published in 2012 in French and held by 1 WorldCat member library worldwide
This thesis is devoted to solving a basic problem of variational analysis which is the search of zeros of maximal monotone operators in a Hilbert space. First of aIl, we concentrate on the case of the extended som of two maximal monotone operators; the search of a zero of this operator is a problem for which the bibliography is not abondant: we purpose a modified version of the forwardbackward splitting algorithm using at each iteration, the epsilonenlargement of a maximal monotone operator, in order to construet a solution. Secondly, we study the convergence of a new bondie algorithm to construet a zero of an arbitrary maximal monotone operator in a finite dimensional space. In this algorithm, intervenes a double polyhedral approximation of the epsilonenlargement of the considered operator
