Annaoui, Ilias. "Essais sur le choix de financement par Equity Lines." Electronic Thesis or Diss., Bordeaux, 2023. http://www.theses.fr/2023BORD0178.
Equity lines financing allows a manager to raise additional funds at any time during an agreed period to strengthen his or her equity. Little recent research has focused on this Equity lines financing mechanism and none on the determinants of capital structure, internal governance mechanisms, and the information content of equity markets. This thesis is structured around a set of interrelated research segments. It explores the use of Equity lines mechanisms to better understand the factors that motivate the use of this type of financing, by examining both the factors specific to companies and those related to their general environment. Our research shows that growth opportunities, liquidity, the degree of development of the stock market (maturity, experience of financial intermediaries, number of transactions, etc.) are the factors that determine the choice of Equity lines financing. This thesis also proves that male executives, who are not entrenched, relatively old and less educated, also serve as chairman of the board of companies with managerial shareholding. Our work evaluates the information content of the announcement of the Equity lines issue. We show that the negative market reaction around the announcement date, and the persistence of this effect after the announcement date, support the hypothesis of inside information reporting. The various findings of this thesis add to the body of knowledge on capital structure, corporate governance and financial markets. The consequences on the risks inherent in investments using this financial instrument are questionable. These include the risk of losing the capital invested, which is associated with strong downward pressure on the share price

Xun, Zhou. "Econometric analysis of subjective well-being, preference, perception and dynamics." Thesis, Aix-Marseille, 2014. http://www.theses.fr/2014AIXM2026/document.
This dissertation studies option variables. These opinions cover specially economic questions such as the level of wellbeing, financial situations, the minimum income question and the preference for redistribution. The treatment of these opinion variables and their relation to conventional economic questions such as income level or dynamics requires the use of special micro-econometric models. In this dissertation, the dynamics panel models are used to study the job status and income mobility. In the 6 chapter, we discuss the dynamic Tobit model with an emphasis on initial conditions. The choice between fixed or random effect is another question. Because subjective variables are ordinal and discrete, the identification of fixed effects is problematic. Random effects are better identified while the estimation difficulty increases with the integration dimension. To solve that, I use intensively simulation method in the study of dynamic multinomial logit model or dynamic tobit model. It is also been applied in the trivariate probit model to measure the conditional correlations among more than 2 ordinal variables

This thesis consists of three chapters on longitudinal data analysis. Linear mixed models are discussed, both random effects (where individual intercepts are interpreted as random variables) and fixed effects (where individual intercepts are considered unknown constants, i.e., they must be estimated). Furthermore, robust models (resistant to outliers) and efficient models (with low estimator variability) are proposed in the scope of repeated measures. The second part of the thesis is dedicated to quantile regression, which explores the full conditional distribution of an outcome given its predictors. It introduces a more general method for dealing with heteroscedastic variables and longitudinal data. The first chapter is motivated by evaluating the statistical association between air pollution exposure and children and adolescents' lung ability among six months. A robust linear mixed model combined with an equally robust principal component analysis is proposed to deal with multicollinearity between covariates and the impact of extreme observations on the estimates. Huber and Tukey loss functions (M-estimation examples) are considered to obtain more robust estimators than the least squared function usually used to estimate the parameters of linear mixed models. A finite sample size study is carried out in the case where the covariates follow linear time series models with or without additive outliers. The impact of time correlation and outliers on fixed effect parameter estimates in linear mixed models is investigated. In addition, weights are introduced to reduce the estimates' bias even more. The study of the real data revealed that the robust principal component analysis exhibits three principal components explaining more than 90% of the total variability. The second principal component, which corresponds to particles smaller than 10 microns, significantly affects respiratory capacity. In addition, biological indicators such as passive smoking have a negative and significant effect on children's lung ability. The second chapter analyses fixed effect panel data with three different loss functions. To avoid the number of parameters increases with the sample size, we propose to penalize each regression method with the least absolute shrinkage and selection operator (LASSO). The asymptotic properties of two of these new techniques are established. A Monte Carlo study is performed for homoscedastic and heteroscedastic models. Although the model is more challenging to estimate in the heteroscedastic case for most statistical methods, the proposed methods perform well in both scenarios. This confirms that the proposed quantile regression methods are robust to heteroscedasticity. Their performance is tested on economic panel data from the Organisation for Economic Cooperation and Development (OECD). The objective of the third chapter is to simultaneously restrict the number of individual regression constants and explanatory covariates. In addition to the LASSO, an adaptive LASSO is proposed, which enjoys oracle proprieties, i.e., it owns the asymptotic selection of the true model if it exists, and it has the classical asymptotic normality property. Monte Carlo simulations are performed in the case of low dimensionality (much more observations than parameters) and in the case of moderate dimensionality (equivalent number of observations and parameters). In both cases, the adaptive method performs much better than the non-adaptive methods. Finally, we apply our methodology to a cohort dataset of moderate dimensionality. For each chapter, open-source software is written, which is available to the scientific community
Esta tese consiste em três capítulos sobre análise de dados longitudinais. São discutidos modelos lineares mistos, tanto efeitos aleatórios (onde interseptos individuais são interpretados como variáveis aleatórias) quanto efeitos fixos (onde interseptos individuais são considerados constantes desconhecidas, ou seja, devem ser estimadas). Além disso, modelos robustos (resistentes a outliers) e modelos eficientes (com baixa variabilidade de estimadores) são propostos no âmbito de medidas repetidas. A segunda parte da tese é dedicada à regressão quantílica, que explora toda a distribuição condicional de uma variável resposta dado suas preditoras. Ela introduz um método mais geral para lidar com variáveis heterocedásticas e dados longitudinais. O primeiro capítulo é motivado pela avaliação da associação estatística entre a exposição à poluição do ar e a capacidade pulmonar de crianças e adolescentes durante um período de seis meses. Um modelo linear misto robusto combinado com uma análise de componentes principais igualmente robusta é proposto para lidar com a multicolinearidade entre covariáveis e o impacto de observações extremas sobre as estimativas. As funções de perda Huber e Tukey (exemplos de \textit{M-estimation}) são consideradas para obter estimadores mais robustos do que a função de mínimos quadrados geralmente usada para estimar os parâmetros de modelos lineares mistos. Um estudo de tamanho de amostra finito é realizado no caso em que as covariáveis seguem modelos de séries temporais lineares com ou sem outliers aditivos. É investigado o impacto da correlação temporal e outliers nas estimativas de parâmetros de efeito fixo em modelos lineares mistos. Além disso, foram introduzidos pesos para reduzir ainda mais o enviesamento das estimativas. Um estudo em dados reais revelou que a análise robusta dos componentes principais apresenta três componentes principais que explicam mais de 90% da variabilidade total. O segundo componente principal, que corresponde a partículas menores que 10 micrômetros, afeta significativamente a capacidade respiratória. Além disso, os indicadores biológicos como o tabagismo passivo têm um efeito negativo e significativo na capacidade pulmonar das crianças. O segundo capítulo analisa dados de painel com efeito fixo com três diferentes funções de perda. Para evitar que o número de parâmetros aumente com o tamanho da amostra, propomos penalizar cada método de regressão com least absolute shrinkage and selection operator (LASSO). As propriedades assimptóticas de duas dessas novas técnicas são estabelecidas. Um estudo de Monte Carlo é realizado para modelos homocedásticos e heterosecásticos. Embora o modelo seja mais difícil de estimar no caso heterocedástico para a maioria dos métodos estatísticos, os métodos propostos têm bom desempenho em ambos os cenários. Isto confirma que os métodos de regressão quantílica propostos são robustos à heterocedasticidade. Seu desempenho é testado nos dados do painel econômico da Organização para Cooperação e Desenvolvimento Econômico (OCDE). O objetivo do terceiro capítulo é restringir simultaneamente o número de constantes de regressão individuais e covariáveis explicativas. Além do LASSO, é proposto um LASSO adaptativo que permite a seleção assimptótica do modelo verdadeiro, se este existir, e que desfruta da propriedade de normalidade assimptótica clássica. As simulações de Monte Carlo são realizadas no caso de baixa dimensionalidade (muito mais observações do que parâmetros) e no caso de dimensionalidade moderada (número equivalente de observações e parâmetros). Em ambos os casos, o método adaptativo tem um desempenho muito melhor do que os métodos não adaptativos. Finalmente, aplicamos nossa metodologia em um conjunto de dados de coorte de dimensionalidade moderada. Para cada capítulo, um software de código aberto é escrito e colocado à disposição da comunidade científica

This thesis contributes to the literature in three main areas of research about capital structure: the determinants of capital structure, the profitability and the labour demand. (i) The theoretical basis of the determinants of capital structure shows that there are three models that explains the capital structure: Trade-Off theory, Pecking Order theory and Market Timing theory. Further, the empirical evaluation shows a positive effect of the adjustment costs and the tangibility. On the other hand, growth opportunity, non-debt tax shield and profitability are negatively correlated with debt. (ii) The impact of capital structure on profitability can be explained by three essential theories: signal theory, tax theory and the agency costs theory. The empirical analysis allowed to distinguish three different groups of sectors: for the first group, the capital structure has no impact on profitability. The second, it is the group where the debt affects negatively the profitability in a linear way. The last group is characterized by the presence of a negative effect in a linear and nonlinear way. (iii) Theoretically, a negative impact of the capital structure on labour demand is expected. The empirical application shows heterogeneity of behavior between sectors regarding the impact of debt on the demand for labor; therefore, there are three different groups of sectors (i.e. no effect, negative linear effect, and linear and non linear negative effect). Furthermore, the magnitude of the effect of debt on the labour demand and on the profitability depends not only of the sector, but also of the size of company

Undulatory wave-based self-propulsion like used by fish may be a suitable alternative to traditional propeller-based propulsion for underwater vehicles. The use of undulatory propulsion implies a certain degree of structural flexibility will be present, hence consideration of both fluid and structure is critical to assessing the behavior of this form of propulsion. In this thesis, a novel segregated fluid-structure interaction (FSI) coupling scheme is developed between a finite element structure solver and a 2D unsteady panel method fluid solver with discrete vortex particle wake approach. The different components of the FSI solver are validated first individually and then as a whole using the case of a flexible two-dimensional plate in pure heave. The scaling law relating input swimming variables and the resulting swimming speed is then reproduced and the importance of drag to these relations is elucidated.A self-propelled swimmer whose beam-like structure and rigid body motions are resolved is then examined under the influence of an imposed bending moment distribution. A curvature-based, delayed proprioceptive feedback is then applied to deform the self-propelled swimmer. Feedback based swimming was found to be distinct from active, imposed bending moment swimming. A simplified one degree of freedom model was found to qualitatively describe the feedback swimmer behavior. A swimmer using muscle-like elements is then assessed to determine the relative importance of different muscle properties with the aim of identifying if the non-linear behavior of muscles is beneficial to self-propulsion. Finally, a three-dimensional, thin plate in pure heave is examined with the aim of determining to what extent an 3D panel method can be used in lieu of computationally expensive viscous flow approaches self-propulsion analysis in 3D

In this thesis based on works the author goes from two previous studies on the profitability of loyalty and customer potential determination to make a statement : part of the profitability of loyalty and of the potential for a brand is based on the reachable share of turnover done by the competition ; the catch rate.In this new work it is shown that the catch rate is based on the elasticity of the share of category requirement. From a review of the literature and several modeling on scanning panel data the author demonstrates on several markets that elasticity of the share of category requirement is limited and predictable.Then it’s in taking into account this small difference that a brand can estimate the “catchable” rate and therefore the profitability of loyalty and potential of a customer
