Cette thèse étudie le choix des régimes de change dans des contextes économiques particuliers. La première partie (Chapitres 1 et 2) considère le cas des petits pays dont les dettes sont libellées en monnaies étrangères et celui d’une région constituée de tels petits pays lorsqu’il existe une similitude dans la composition des paniers définissant leurs taux de change effectifs. La deuxième partie de la thèse (Chapitres 3 et 4) se penche sur la considération des différents régimes de change dans le contexte monétaire de trappe à liquidité comparativement à un environnement monétaire traditionnel. En se basant sur une modélisation théorique de type DSGE, l’économétrie bayésienne et des données de panel, la thèse utilise principalement l’analyse des fonctions de réponses, de bien-être et de désalignements monétaires comme critères de comparaison de plusieurs régimes monétaires alternatifs. Les principaux enseignements de cette thèse se résument ainsi. Le change flexible semble être le meilleur régime pour des petites économies ouvertes comme ceux de l’Asie du Sud-Est. Au niveau régional, il est montré le ciblage effectif conduit à une stabilité des taux de change bilatéraux de la région, une sorte de fixité des taux de change qui ressemblerait à une zone monétaire de facto. Dans le contexte monétaire de trappe à liquidité, on trouve que,contrairement à la croyance commune lors la crise de la zone euro, l’union monétaire est plus performante que des politiques nationales de change flexible. Seule une intervention sur le taux de change nominal pourrait permettre au régime de change indépendant de dominer l’union monétaire. A travers une analyse théorique et empirique de l’effet de la trappe à liquidité sur l’ampleur des désalignements monétaires, il est aussi montré que la contrainte ZLB tend à réduire le désalignement monétaire dans une union monétaire comparativement aux politiques nationales de flottement.Cela plaide en faveur du renforcement de l’intégration monétaire au sein d’une union durant la période de trappe à liquidité. / This thesis investigates the choice of exchange rate regimes in specific economic contexts. The first part of this work (Chapters 1 and 2) considers the case of small open economies with foreign-currency denominated debt and that of a region where there is a similarity among trade-weighted currency baskets of countries. The second part of the thesis (Chapters 3 and 4) focuses on the study of exchange rate regimes and monetary integration in a liquidity trap environment relative to “tranquil” times. Based on dynamic stochastic general equilibrium (DSGE) models and Bayesian and Panel data econometrics, the thesis mainly uses the analyses of impulse responses, welfare and currency misalignments as comparison criteria among alternative currency regimes.The key lessons from this work are summarized as follows. For small open economies heavily in debted in foreign currency, like those of Southeast Asia, the flexible exchange is the best regime, followed by intermediate and fixed exchange rate regimes. At the regional level, it is shown that the exchange rate targeting regime leads to a stability of intra-regional bilateral exchange rates, which is a sort of fixity of exchange rates similar to a “de facto currency area”. In the context of a liquidity trap, we find that, contrary to common belief during the Euro area crisis, the currency union welfare dominates the independent floating regime. Only a central bank intervention in the form of a managed float policy could allow the independent floating to outperform the monetary union.Through both the empirical and theoretical analyses of the liquidity trap effects on currency misalignments, it is shown that the ZLB constraint tends to reduce currency misalignments compared with the independent floating policy. This suggests a reinforcement of the monetary integration within a monetary union during the liquidity trap

This Ph.D. thesis is aimed at inbound tourism in the Czech Republic, analysis of statistical data and their development in the period of years 2004 -- 2013, characteristics of the main source markets for the Czech Republic, and analysis of motives regarding participants of outbound tourism to the Czech Republic in the observed countries. The principal aim is to analyze and compare intensity of motives of the selected geographic, demographic, socio-economic, and behavioral segments for visits to the Czech Republic. An integral part of the aim is to suggest further possibilities of the motivation research and their exploitation in the marketing practice of the tourism industry. The author defines all theoretical terms closely connected with the tourism market segmentation, motives and motivations to travel including interesting view of them throughout history. It is evident that the travel motives influenced by various factors are differentiated parallely with the human society development. The author characterizes the Czech Republic destination offer and evaluates its inbound tourism in the period of years 2004 -- 2013 by means of 4 main indicators: number of guests, number of overnight stays, average length of stay, foreign currency incomes. The author also evaluates the researches focused on perception of the Czech Republic abroad that was carried out by the institutions representing the Czech Republic abroad. The detailed analysis of travel motivations was performed by the author herself in the form of questionnaires. Results of these analyses bring impulses to other possibilities of the research in the field of inbound tourism not only in the academic sphere but also in research work of state and public authorities, and in practice when creating tourism products and communications mix.

Diploma thesis concerns about legal regulations of real estate by new civil codex with reflection to the previous and international legal regulation.The aim of the thesis is to assess the functionality of new civil code and its benefits in the real estate investment transactions in Czech Republic. This analysis is supported with overview of transfrontier real estate acquisitions made by foreign investors in Czech Republic and additionally also real estate investments of Czech investors abroad. This thesis therefore tries to provide answers to multiple questions ranging from analysis of new civil codex regulation, its impacts, risks and functionality then secondly its similarities in comparison to foreign law regulation (of Germany, Austria, Great Britain, Italy and France). From the perspective of transfrontier real estate acquisitions this thesis concerns about law acknowledgement for foreigner parties in real estate transactions in Czech Republic and counterbalance of the similar rights on the side of Czech residents in reciprocal acquisition process. The analysis is supported by the debate of accuracy of either liberal or protectionist attitude to foreign real estate investors' regulation with a reflection to current international political, sociological and economical course of events.

Cette thèse a pour ambition d’analyser si la performance environnementale, sociale et de gouvernance (ESG) est intégrée par les marchés de la dette d'entreprise et souveraine. Le premier chapitre se concentre sur les informations ESG publiés à contenu négatif et leur impact négatif sur le coût de la dette. Plus exactement, dans les secteurs industriels et utilitaires les événements négatifs sociaux et de gouvernance font augmenter le coût de la dette. Également, un bon niveau général de performance ESG agit comme un mécanisme d'assurance contre ces événements négatifs. Dans un deuxième chapitre seront présentés les résultats d’une simulation de portefeuille intégrant la performance ESG d'entreprise. Un gérant de portefeuille peut améliorer le niveau agrégé de la performance ESG du portefeuille de 1,5 écart-type sans faire baisser la performance financière. Ainsi, le gérant peut combiner cette intégration avec des stratégies d'allocation d'actif financiers ou des stratégies de rendement absolu. Dans un troisième chapitre les résultats sur la réduction du coût de la dette dû à une bonne performance environnementale et sociale de souverains émergents seront analysés. Enfin dans le quatrième chapitre je décris comment la performance de gouvernance des souverains influence la différence entre le yield émis en devise étrangère et celui émis en devise locale. Dans les pays développés cette différence augmente avec le risque politique, i.e. le yield étranger augmente plus rapidement que le yield domestique. Dans les pays émergents, c'est l’effet inverse qui est observé. Cette différence entre les deux yields varie plus fortement avec un taux croissant de la dette domestique détenue par des investisseurs étrangers. / This thesis analyzes if and to what extent debt markets value the environmental, social and governance (ESG) performance of firms and sovereigns. The first chapter shows that negative ESG news has a negative impact on the cost of debt of firms. The news relates to environmental and social events within the industrial/utilities sector. In this sector, a sound corporate social performance acts as an insurance against the adverse impact of negative environmental events on bond prices. The second chapter reveals that ESG scores integrated into portfolios do not change the financial performance ex post. A portfolio manager can increase the average ESG rating of her portfolio by 1.5 standard deviations without incurring cost. This leaves substantial room and opportunity for ESG ratings to be combined with asset allocation or absolute return strategies. The third chapter shows how ESG performance is linked to a lower cost of debt of emerging sovereigns. Research indicates that an emerging country’s average cost of capital decreases with its positive environmental and social performance. The fourth chapter discusses how governance performance may influence the spread of debt denominated in local and foreign currency. In developed countries, the spread between a foreign currency yield and a hedged local currency yield increases with our political risk indicator, i.e. the foreign yield increases faster than the domestic one. For emerging countries, the reverse trend is true. Interestingly, the foreign currency and local currency yield spreads move significantly stronger in absolute terms with increasing foreign investment participation in both emerging countries and developed countries’ debt markets.
