La thèse comporte deux parties. Dans la première partie (Chapitres 1 et 2), un examen des déterminants des interventions officielles sur le marché des changes est proposée. Dans la second partie (Chapitres 3 et 4), c'est la problématique des interventions dites « secrètes » qui est étudiée. <p><p>Chapitre 1: « Talks, financial operations or both »<p><p>Ce chapitre propose une nouvelle approche aux fonctions de réaction permettant d’examiner, dans un même modèle, les déterminants des différents types d’interventions (les interventions effectives et les interventions orales). Le modèle permet de mieux comprendre les choix stratégiques des autorités (opérations financières ou simple politique de communication) et d’en évaluer le degré de substituabilité ou de complémentarité.<p><p>Chapitre 2 :« The institutional organization underlying interventions »<p><p>La structure institutionnelle sous-jacente au processus d’intervention (interactions entre le Ministère des finances et la banque centrale) est explicitement incorporée dans le modèle proposé dans ce chapitre. Cette approche permet d’évaluer, dans quelle mesure, le Ministère des finances (l’autorité responsable de la politique de change), en intervenant sur le marché, internalise les objectifs de la banque centrale(l’agent du Ministère pour l’implémentation des ordres d’intervention).<p><p>Chapitre 3 :« The secrecy puzzle »<p><p>Ce chapitre propose une évaluation empirique des différents arguments théoriques expliquant le recours aux interventions secrètes. Le travail repose sur l’examen économétrique d’une fonction de stratégie, dans laquelle, des déterminants relatifs à la décision d’intervenir secrètement d’une part et, d’autre part, des déterminants relatifs à la détection des interventions par le marché sont incorporés.<p><p>Chapitre 4 :« A unified approach to interventions »<p><p>Un modèle unique, permettant d’expliquer les trois étapes du processus d’intervention, est proposé dans ce chapitre. Ces trois étapes sont relatives (i) au choix d’intervenir, (ii) au choix d’intervenir de façon secrète et (iii) à la perception des interventions par le marché. Grâce à l’inclusion de déterminants spécifiques pour ces différentes étapes, cette approche multidimensionnelle permet d’appréhender leurs interrelations et, donc, de mieux comprendre les différents arbitrages réalisés par les autorités lorsqu’elles décident d’intervenir. / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

Crisis communication has emerged as a specialised study field for public relations scholars and practitioners in the past 17 years. It is suggested that several gaps in current crisis communication literature exist. A notable focus has been given to the planning, prevention and recovery stages with lesser attention placed on the crisis response stage. A comprehensive conceptual framework to guide communication decision-makers during this critical period has not yet been developed. In addition, crisis communication studies appear to be predominantly Western based. This qualitative study attempts to address these gaps. The focus is on the crisis response stage, with particular emphasis on communication with the journalists who work for media organisations. It is acknowledged that the success of a crisis management effort is profoundly affected by what an organisation says and does during a crisis - termed the crisis response (Benoit 1997; Coombs 2004). Literature and data drawn from South African case studies is translated into a conceptual framework which acknowledges the importance of context, flexibility and constant feedback/monitoring of the environment on crisis communications. The findings of this qualitative study are in line with the current post-modern organisational values that are increasingly emphasised in national and international literature. The study especially makes a unique contribution by applying these values to a conceptual model of communication between the organisation and the media during times of crisis. The model is designed to assist an organisation to protect its image during a crisis in the following ways: * Convince the media that there is no crisis (in the case of unfounded rumours); * Encourage them to view the crisis in a less negative light by acknowledging the organisation's interpretation of events. * Influence the media to see the organisation more positively through the effective management of the crisis. / Communication Science / D.
