Essays on eco-innovation / Essais sur l'éco-innovationOzusaglam, Serdal 10 April 2014 (has links)
Le Chapitre 1 propose un survol de la littérature consacrée à l'éco-innovation. A la lumière des travaux passés en revue, l'éco-innovation n’est pas encore un concept bien stabilisé : sa définition même continue d'évoluer, appelant des corrections et des précisions. Ce chapitre accorde une attention particulière au rôle de la règlementation, qui est souvent présentée dans la littérature comme un déterminant essentiel de l'éco-innovation, notamment quand l'innovation concerne un procédé de fabrication. Une controverse demeure à ce propos, en particulier quand la règlementation repose sur des normes environnementales peu contraignantes, voire facultatives (telle la norme ISO 14001). Le processus de diffusion de l'éco-innovation est un autre objet de controverse dans la littérature.[...]. Le Chapitre 2 va donc s'intéresser au premier point de controverse, à savoir le rôle des règlementations environnementales ayant une dimension facultative, comme les normes de type ISO 14001. A l'aide d'une analyse par appariement sur les scores de propension, nous examinons l'effet de l'adoption de normes de type ISO 140001 sur la performance des entreprises (mesurée à partir de la Valeur Ajoutée).[...] Le Chapitre 3 s'intéresse à savoir le processus de diffusion de l'éco-innovation. En raison des contraintes posées par les données disponibles, cette investigation se fait du point de vue des barrières à, et des déterminants de, l'innovation environnementale.[...] Le Chapitre 4 exploitant les données des Enquêtes Communautaires sur l'Innovation de 2008 (CIS 2008), qui contiennent un module spécifiquement dédié à l’éco-innovation. Ainsi, à la différence du chapitre 3, nous établissons – à l'aide du module spécifique de l'enquête – une typologie originale permettant de distinguer, parmi les entreprises éco-innovantes: (1) les entreprises adoptant une éco-innovation de manière passive, (2) les entreprises adoptant tardivement une éco-innovation de manière stratégique, (3) les entreprises adoptant précocement une éco-innovation de manière stratégique, (4) les éco-innovateurs stratégiques tardifs et (5) les éco-innovateurs stratégiques précoces.[...] / Environmental innovation or eco-innovation is considered one of the most significant paradigm shifts in the innovation behaviour. The specificity of eco innovation lies in the fact that environmental improvement, in addition to technological advancement, is the main reason of its development. By combining these two objectives, eco-innovation has become one of primary tools in the search to solve the world’s environmental problems and sustainability challenges. Despite its prevalence, there is still more to be discovered within the eco-innovation literature. The drivers of and barriers to eco-innovation discussion is one of the most significant amongst all. More notably, the role of a firm’s social, technological, economic and organizational characteristics within the eco-innovation process has been little studied. With this Ph.D. thesis we aim to fill the existing gap with four distinct research articles. [...] Chapter 2 investigates, firstly, whether firms’ internal characteristics have an impact on the adoption of voluntary environmental standards. Secondly, the causal effect of adoption of environmental standards on the firms performance. Based on the empirical evidence obtained, we show that medium-size, high-tech manufacturing firms operating at the EU level and using quality standards are more likely to adopt these standards earlier. [...] In Chapter 3, we stressed the significance of a firm’s structural characteristics in another context and aimed at investigating the role these characteristics play in realization of product and/or process eco-innovation. [...] In Chapter 4 we moved forward the analyses conducted in Chapter 3 to another context and examined the influence of firm’s economic, technological, organisational capabilities on the eco-innovation behaviour for different types of product, process, organisational or marketing eco-innovators. The results of our empirical analyses point out the marginal impacts of firm’s characteristics changes with respect to type of eco-innovator. [...]

Previous issue date: 2016-12-07 / The objective of this paper was to analyze how the relation between the simultaneity of proxies of the earnings quality. It was sought to achieve this goal through the formulation of an empirical model of structural equations based on evidence presented by the review of literature about the earnings quality. The sample used in this study included the firms that traded shares in the US capital market from 1985 to 2015. It was used as proxies for earnings quality consolidated according to Dechow, Ge and Schrand (2010), which was earnings management used by Paulo (2007), quality of accruals (DECHOW; DICHEV, 2002) and value relevance by the model of prices (COLLINS; MAYDEW; WEISS, 1997), while for firms chacarteristics were used total debt and firm size. The initial results obtained by multiple linear regression showed, in general, that for the proxies quality of the accruals and value relevance the relations of the characteristics of the firms were presented according to the evidences of the literature (DECHOW; GE; SCHRAND, 2010); While for earnings management, the firm size relationship was positive, contrary to the literature. Regarding the measurement of the quality of information as a latent variable, that is, incorporating all the dimensions analyzed, the relationships corroborated the evidence pointed out in the literature, that is, the management of results reduced the quality of the accounting information and the quality of accruals and value relevance increased, whereas size was positively related to the earnings quality, while debt negatively impacted the quality of accounting information. Regarding the quality of the adjustment statistics, they did not meet the satisfactory statistical requirements, according to Marôco (2010), for validation of the tested model. Thus, measuring the earnings quality simultaneously by structural equations produces the effects capable of explaining the quality of accounting information as a latent variable when realigned with the characteristics of firms. / O objetivo deste trabalho foi analisar como se dá a relação entre a simultaneidade das proxies da qualidade da informação contábil. Buscou-se alcançar este objetivo através da formulação de um modelo empírico por equações estruturais baseado nas evidências apresentadas revisão da literatura acerca da qualidade da informação contábil. A amostra empregada neste estudo contou com as firmas que negociaram ações no mercado norte americano de capitais no período de 1985 a 2015. Utilizaram-se como proxies da qualidade da informação contábil variáveis consolidadas conforme Dechow, Ge e Schrand (2010), as quais foram o gerenciamento de resultados pelo modelo de Paulo (2007), qualidade dos accruals (DECHOW; DICHEV, 2002) e value relevance pelo modelo de preços (COLLINS; MAYDEW; WEISS, 1997), enquanto que para a característica das firmas utilizou-se o endividamento total e o tamanho das firmas. Os resultados iniciais realizados por regressão linear múltipla apontaram, de modo geral, que para as proxies qualidade dos accruals e value relevance as relações das características das firmas apresentaram-se de acordo com as evidências da literatura (DECHOW; GE; SCHRAND, 2010), ao passo que para o gerenciamento de resultados, a relação do tamanho da firma se mostrou positiva, contrariando a literatura. No que diz respeito a mensuração da qualidade da informação como variável latente, isto é, incorporando todas as dimensões analisadas, as relações corroboraram as evidências apontadas na literatura, ou seja, o gerenciamento de resultados reduziu a qualidade da informação contábil e a qualidade dos accruals e o value relevance a aumentaram, ao passo que o tamanho se relacionou positivamente com a qualidade da informação contábil, enquanto que o endividamento impactou negativamente a qualidade da informação contábil. No que diz respeito as estatísticas de qualidade do ajustamento, elas não alcançaram os requisitos estatísticos satisfatórios, de acordo com Marôco (2010), para validação do modelo testado. Sendo assim, mensurar a qualidade da informação contábil de forma simultânea por equações estruturais, produz os efeitos capazes de explicar a qualidade da informação contábil como variável latente quando relacionados com as características das firmas.
