Les services de tourisme de nature fournis par le patrimoine naturel sont des produits composites et le plus souvent non marchands. Financer la préservation de ce patrimoine par ses usagers est donc tributaire d’une connaissance fine des préférences des touristes et de la valeur qu’ils accordent à la nature. Cette thèse vise de contribuer au débat sur le financement de la préservation des espaces naturels et leurs aménités par les touristes en considérant comme point d’entrée l’hétérogénéité des comportements individuels selon une double perspective. D’abord, nous examinons les déterminants de cette hétérogénéité en termes de la demande de séjours de tourisme en pleine nature, ensuite nous nous penchons sur l’analyse de l’hétérogénéité en termes du mécanisme de contribution choisi par les agents, à savoir, un mécanisme de contribution volontaire ou un mécanisme de contribution contre une service rendu. Les motivations non-économiques de contribution et plus globalement les facteurs cognitifs, en lien avec d’autres caractéristiques individuelles des touristes structurent notre réflexion tout au long de cette thèse. Enfin, les résultats obtenus via cette analyse sont mis en contraste avec ceux issus de la mis en exergue d’un instrument de participation des touristes déjà mis en oeuvre: la taxation. Nous proposons une application aux séjours d’été effectués dans la région de l’estuaire de la Gironde en France. / Tourism services provided by natural environment are composites goods and often non-market. Funding the preservation of this heritage by its own users depends on a profound knowledge of the preferences of tourists and the value they place on nature. This thesis aims to contribute to the debate on the funding of natural areas and amenities preservation programs by tourists. To do so we consider as an entry point the individual’s behavior heterogeneity from two perspectives. First, we examine the determinants of heterogeneity in terms of the demand of nature tourism stay, and then we focus on the analysis of heterogeneity in terms of the contribution mechanism chosen by the agents, e.g., voluntary contribution mechanism or contribution mechanism against a service. The non-economic motivations for contributing and overall cognitive factors, considered in conjunction with other tourists’ individual characteristics, is the main thread structuring our reflection throughout this thesis. Finally, the results obtained through this analysis are contrasted with those from an instrument of tourists contributions already implemented: taxation. We propose an application for summer stays in the region of the Gironde estuary in France.

v Abstract This thesis proposes a theoretical framework for application of ethics in banking and analyses effects of such application on financial performance of banks. A sentiments-adjusted economic motivation enables employment of ethical concepts, such as universality and humanity, in economics as well as banking. Then, using Bankscope data of more than 80,000 bank-year observations for the years 2003-2013, it is shown that banks applying ethics have higher exposure to real economy and less volatile Return on Equity. A consequent analysis revealed that in comparison with their closest peers those banks have lower profitability caused by higher relative costs that conversely result in lower loan losses.

The thesis analyses a dispute of two anarchist movements promoting Anarcho-Capitalism and an automated non-monetary economy. It asks the question whether the dispute can be explained in terms of paradigm conflict and not exclusively in political terms . The goal is to search for signs of scientific paradigm in an apparently ideological dispute. The thesis also examines the reasons why did the debate deteriorate into a personal and moral conflict of the representatives. The method of analysis is Grounded Theory, with reference to authors who interpret Kuhn's paradigm conflict as the consequence of an unconscious language barrier. Paradigm was operationally defined as a hierarchy of concepts with physical reference, theoretical network of the concepts and the scientific field objectives. The field objectives are the only reliable reference points between paradigms. The thesis sums up the debate between Anarcho-Capitalists and proponents of Resource-Based Economy and recovers the scientific answers and field objectives which were demanded yet missing in the debate. The thesis concludes that the debate can legitimately continue and that the ideological differences were mostly caused by a different scope of technical instruments and their describing paradigms, regardless of historical origin and...
