This dissertation explores how institutional settings regulating the media and campaigns affect voter participation. The broader question is what types of political communication systems are likely to produce the most engaged and participatory citizens as well as equal participation. Assuming that political participation is affected by its underlying costs and benefits, I hypothesize that political communication systems that lower information costs for voters have higher turnout levels and reduce upper class bias. Political communication systems are measured by media systems, access to paid TV advertising, and campaign finance laws. In the country-level turnout models, investigating seventy-four electoral democracies, I find that public broadcasting systems increase voter turnout, while changing the effect of paid advertising. Public broadcasting systems that allow paid TV advertising have a higher turnout levels than those that ban paid advertising. Conversely, paid advertising in private broadcasting systems have a negative marginal effect on voter turnout. On the other hand, campaign finance laws that allow more money to enter election campaigns increase voter participation. So campaign contribution and spending limits depress turnout and public finance increases it. The hierarchical models in Chapter 6 show that political communication systems also change the relationship between individual socioeconomic status and voter participation. Generally political communication environment that lower information costs for voters reduces socioeconomic bias for voters. Public broadcasting systems, access to paid TV ads, and free TV time, thus, mitigate the effect of education on voting. Additional investigation also shows that the age gap between voters and nonvoters is conditioned by different types of political communication systems. Both partisan press and public direct funding promote younger citizens’ participation, thus decreasing the generation gap. In contrast, campaign contribution/expenditure limits enlarge such gap. Broadcasting systems also affect the effect of age on voting. Because older people spend more time watching television than younger ones, the type of broadcasting system has a disproportionately larger impact on older citizens. / text

Les administrations financières sont primordiales dans le cadre de la mise en œuvre des politiques publiques, et d'autant plus dans les circonstances actuelles qui conduisent à diminuer les dépenses publiques. Elles sont aussi un facteur important dans la modernisation de l’État. Les lois de finances votées par le Parlement et élaborées par le gouvernement sont mises en œuvre principalement par les administrations financières publiques. Il est essentiel que celles-ci disposent des outils pour les exécuter. Ainsi au XXIe siècle, la structure administrative financière publique française se modernise, à la foi en empruntant des modes d’organisation et de gestion du secteur privé et en s’appuyant sur l’outil numérique pour fiabiliser l’information financière publique. Face aux contraintes budgétaires liés aux engagements européens, et à l’évolution sociétale qu’entraîne le numérique, ces entités doivent être des catalyseurs d’une maîtrise de la gestion des deniers publics. / Financial administrations are crucial in the implementation of public policies, and all the more under the present circumstances which lead to decrease public expenses. They are also an important factor in the modernization of the State. The finance laws, voted by the Parliament and developed by the government, are mainly operated by public financial administrations. It is therefore essential that they have the tools to implement them. So in the XXIth century, the French public financial administrative structure is modernizing, both by borrowing methods of organization and management of the private sector, and using the digital tool to enhance reliability of the public financial information. Faced with the budgetary constraints linked to European commitments, and the societal evolution that digital entails, these entities must be catalysts for controlling the management of public funds.

La thèse vise à analyser le système des finances publiques dans les trois pays du Maghreb (Maroc, Algérie et Tunisie) en mettant l’accent sur les insuffisances aux plans juridique, institutionnel, administratif, fiscal et financier, sur les contraintes structurelles et les tendances lourdes au regard des exigences de transparence et de la performance et d’exposer des axes stratégiques d’alternatives crédibles pour l’amélioration des procédures fiscales et budgétaires. Les pays du Maghreb sont donc à la recherche d’un nouveau modèle de gouvernance plus ouvert, plus transparent et plus responsable. La réforme budgétaire s'inscrit dans le contexte d'une réforme en profondeur des Etats du Maghreb à travers le renforcement du contrôle budgétaire et la modernisation de l'administration publique, notamment de ses modes de gestion financiers et managériaux tant au niveau central que déconcentré par le recours à la programmation pluriannuelle (CDMT), la globalisation des crédits, la contractualisation et la déconcentration budgétaire. Pour y parvenir, la réforme budgétaire conditionne une volonté politique forte et un pilotage administratif permanent. En outre, elle doit être comprise dans le sens le plus global, pragmatique, progressif, inclusif et participatif d'une démarche fondée sur le passage d’un modèle uniquement structuré par nature de moyens et contrôlé par la régularité au regard de la réglementation, à un modèle également structuré par les objectifs des politiques et contrôlé par les résultats / The thesis aims at analyzing the system of public finances in the three Maghreb countries (Morocco, Algeria and Tunisia) by focussing on the insufficiencies to the plans legal, institutional, administrative, tax and financial, on the constraints structural and the heavy tendencies with the glance as of requirements of transparency and of the performance and to expose strategic axes of credible alternatives for the improvement of the tax and budgetary procedures. The Maghreb countries are thus in search of a new model of governance more opened, more transparent and more responsible.The budgetary reform falls under the context of an in-depth reform of the States of the Maghreb through the budgetary intensifying of the control and the modernization of the public administration, in particular of its financial and managerial ways of managing as well at the central level as decentralized by the recourse to the multiannual programming (CDMT), the globalisation of the appropriations, the contractualisation and budgetary devolution.For that purpose, the budgetary reform conditions a strong political will and a permanent administrative piloting. Moreover, it must be understood in the direction most total, pragmatic, progressive, inclusive and participative of a approach based on the passage of a model only structured by nature of means and controlled by the regularity in comparison with the regulation, with a model also structured by the objectives of the policies and controlled by the results
