An unprecedented process of financial consolidation has taken place in the European Banking Sector over the past 20 years, which in the Visegrad countries was combined with economic transformation. As such, analysis of mergers and acquisitions is made with a view to the importace of the recent economic transformation and scope for further economic development and the Thesis is introduced by an analysis of the banking transformation in the Visegrad countries. Afterwards follows a theoretical part describing and analysing European legislation concerning banking mergers and acquisitions, incentives for them, factors, that support and hamper them, and the synergy following banking consolidation and its impact for supervisory bodies. Finally, building on the abovemetioned theoretical knowledge and premises, we apply them to the economic and banking environment of the Visegrad countries, i.e. we analyse the impact of the European cross-border mergers and acquisitions law on structural indicators of the banking sectors in the Visegrad countries.

In this thesis financial movements are considered in terms of foreign direct investment (FDI) and a related way to international banking. In Chapter 2 FDI is analysed in terms of the major G7 economies. Then this is further handled in Chapter 3 in terms of bilateral FDI (BFDI) data related to a broader group of economies and a main mode of analysis the Gravity model. Gravity models are then used in Chapter 4 to analyse bilateral cross border lending in a similar way. While the exchange rate effect is handled in terms of volatility and measured using models of conditional variance. The analysis focused on the bilateral data pays attention to the breakdown of crises across the whole period. With further consideration made of the Euro zone in terms of the study of BFDI and cross border lending. The initial study looks at the determinants of the inflow and outflow of stocks of FDI in the G7 economies for the period 1980-2011. A number of factors, such as research and development (R&D), openness and relative costs are shown to be important, but the main focus is on the impact of the real and nominal effective exchange rate volatility. Where nominal and real exchange rate volatility are measured using a model of generalised autoregressive conditional heteroscedasticity (GARCH) to explain the variance. Although the impact of volatility is theoretically ambiguous inflows are generally negatively affected by increased volatility, whilst there is some evidence outflows increase when volatility rises. In Chapter 3, the effect of bilateral exchange rate volatility is analysed using BFDI stocks, from 14 high income countries to all the OECD countries over the period 1995-2012. This is done using annual panel data with a gravity model. The empirical analysis applies the generalised method of moments (GMM) estimator to a gravity model of BFDI stocks. The findings imply that exports, GDP and distance are key variables that follow from the Gravity model. This study considers the East Asian, global financial markets and systemic banking crises have exerted an impact on BFDI. These effects vary by the type and origin of the crisis, but are generally negative. A high degree of exchange rate volatility discourages BFDI. Chapter 4 considers the determinants of cross-border banking activity from 19 advanced countries to the European Union (EU) over the period 1999-2014. Bilateral country-level stock data on cross-border lending is examined. The data allows us to analyse the effect of financial crises – differentiated by type: systemic banking crises, the global financial crisis, the Euro debt crisis and the Lehman Brothers crisis on the geography of cross-border lending. The problem is analysed using quarterly panel data with a Gravity model. The empirical "Gravity" model conditioned on distance and size measured by GDP is a benchmark in explaining the volume of cross border banking activities. In addition to the investigation of the impact of crises further comparison is made by investigating the impact of European integration on cross-border banking activities between member states. These results are robust to various econometric methodologies, samples, and institutional characteristics.

This thesis analyzes spillover effects of prudential policies on cross-border capital flows in the period from 2000 until 2014 for 64 countries. It estimates the size of the effect, which 9 most common prudential policy tools had on capital flows based on BIS LBS. The findings show spillover effect of general capital requirements and consumer credit capital requirements on the cross-border capital flows. This work provides analysis of spillover effects in several groups of countries with special accent on CEE countries.

This paper presents VAR results on the recent economic history of the U.S and focuses on the dependence of U.S. macrofinancial variables on international capital flows. Both gross and net flows are included in the analysis. The results indicate that cross-border funding has affected the build-up in the U.S. housing market irrespective of how these flows are defined and measured. Both the savings glut hypothesis and the banking glut hypothesis are supported by these findings. However, net banking flows appear to explain the higher volatility in the increase in house prices as well as the mortgage loan boom.

L'objectif de cette thèse est d'évaluer la conduite des politiques macroprudentielles dans une union monétaire hétérogène, comme la zone euro, en s'appuyant sur les très récents développements théoriques et empiriques des modèles en équilibre général dynamique stochastique (DSGE) et de l'économétrie Bayésienne. Dans notre analyse, nous considérons deux faits majeurs caractérisant l'Eurosystème: la divergence des cycles économiques entre le cœur et la périphérie de la zone et l'intégration bancaire à l'origine de spillovers lors de la mise en œuvre de politiques macroprudentielles. Voici les résultats que nous tirons de nos expérimentations. D'abord, la mise en œuvre des mesures de politique macroprudentielle améliore le bien-être au niveau de l'union. Les gains de bien-être plus élevés sont observés lorsque les pays utilisent plusieurs instruments et lorsque la politique macroprudentielle est mise en œuvre de manière granulaire. Cependant, la conduite de la politique macroprudentielle n'est pas forcément bénéfique pour tous les pays participants: dans la plupart des cas, les pays périphériques sont gagnants tandis que les pays du cœur enregistrent des faibles gains de bien-être voire parfois des pertes. Dans nos simulations, nous constatons qu'il existe un équilibre favorisant le bien-être à la fois aux niveaux mondial et national pour tous les participants mais sa réalisation nécessite une intervention d'une autorité fédérale telle l'ESRB. Enfin, l'introduction de prêts transfrontaliers ouvre un nouveau canal de transmission international important qui tend à augmenter les gains de bien-être associées à des mesures macroprudentielles. Ignorer ces prêts bancaires transfrontaliers peut conduire à des résultats fallacieux dans le classement des différents plans d'instauration de la politique macroprudentielle. / The aim of this thesis is to evaluate the conduct of macroprudential policies in an heterogenous monetary union, such as the Eurozone, by borrowing on the very recent theoretical and empirical developments of Dynamic Stochastic General Equilibrium (DSGE) models and Bayesian econometrics. We account for two main patterns of the Eurosystem: the business cycles divergence between core and peripheral countries and the globalization of banking and its spillovers when implementing macroprudential policies. As a main result, the implementation of macroprudential policy measures improves welfare at the global level. The highest welfare gains are observed when countries use multiple instruments and when macroprudential policy is implemented in a granular fashion. However, the conduct of macroprudential policy is not a free lunch for participating countries: in most situations, peripheral countries are winners while core countries record either smaller welfare gains or even welfare losses. In many policy experiments, we find that there exists an equilibrium that combines welfare increases at both the global and national levels for all participants but its enforceability requires a federal action, thus justifying the existence of a coordination mechanism such as the ESRB in the Eurozone. Finally, the possibility of banks to engage in cross border lending introduces an important spillover channel that tends to increase the welfare gains associated to macroprudential measures. Ignoring this phenomenon may lead to fallacious results in terms of the welfare ranking of alternative implementation schemes.
