La recherche menée propose une contribution à l’analyse de la performance des hedge funds dansun contexte d’instabilité des marchés financiers. Ce travail de thèse tourne autour de deux axes deréflexions. Le premier axe se propose d’examiner la structure de dépendance entre les mesures alternativesde performance absolue, en mettant en évidence l’impact du changement de base de donnéeset de période d’analyse sur le classement des indices. Dans ce cadre, nous proposons de comparer laperformance de cinq indices de stratégies issus de trois différentes bases de données. L’analyse esteffectuée sur trois périodes : une période avant crise, une période de crise et une période globale.Nous avons pu montrer que l’évaluation de la performance et la dépendance entre les indicateurssont des éléments fortement sensibles à la période d’analyse. De plus, cette analyse confirme qu’iln’existe pas d’indice "universel" pouvant représenter l’univers des hedge funds. Le deuxième axede réflexion est lié à l’analyse de la stabilité des performances des hedge funds sur trois horizons :le court terme, le moyen terme et le long terme. Il ressort de notre étude que la persistance desperformances des hedge funds n’est pas un phénomène de long terme et que le niveau de persistanceest fortement dépendant de la stratégie d’investissement et de l’indicateur de performance utilisé. / This dissertation provides a contribution to hedge funds performance analysis in a financialmarket instability context. The objective of this thesis is twofold. The first aim is to examine thedependence structure between alternative measures of absolute performance, highlighting the impactof the database switch and analysis period changing on the leaderboard of hedge funds indexes.In this framework, we propose to compare the performance of five hedge funds indexes extractedfrom three different databases. The analysis is conducted over three periods : a pre-crisis period, acrisis period and an overall period. Our findings show that the performance evaluation and dependancebetween performance indicators are highly sensitive to the analysis period. In addition, wefind that there is no "universal" index that can represent hedge funds universe. The second thesis’spurpose is related to the hedge funds performance stability over three horizons : the short term,the medium term and the long term. Firstly, it appears that hedge funds performance persistence isnot a long term phenomenon. Secondly, the persistence level is highly dependent to the investmentstrategy and to the performance indicator used.

The financial crisis of 2008 has been the most significant global economic phenomenon of the new century. Sudden and largely unanticipated, this crisis nonetheless marks the latest in a series of financial panics that forms a welldocumented feature of finance capitalism stretching back to the Dutch Tulip Bubble of 1637 and beyond, including such notorious crises as the South Sea Bubble of 1720, the Railway Shares panics of 1837 and 1847, the Wall Street Crash of 1929, and Black Monday in 1987. These and other crises have fostered a complex and diverse intellectual response - particularly since the South Sea Bubble - that has included interventions not only from economists and economic historians, but poets, dramatists, novelists, and others. This raises the question of whether the novel’s contribution to our wider understanding of financial crises has been fully acknowledged and assessed. In this thesis, the complex and shifting relationship between literary and non-literary responses to financial crisis is explored through an examination of the ideas of political economists, philosophers, journalists, financiers, and others, including Adam Smith, David Ricardo, Lord Overstone, Walter Bagehot, Herbert Spencer, Thorstein Veblen, Joseph Schumpeter, and J.M. Keynes, that situates their theories alongside readings of novels of financial crisis from the 1850s onward.

This thesis develops an early warning system framework for assessing systemic risks and for predicting systemic events, i.e. periods of extreme financial instability with potential real costs, over the short horizon of six quarters and the long horizon of twelve quarters on the panel of 14 countries both advanced and developing. Firstly, Financial Stress Index is built aggregating indicators from equity, foreign exchange, security and money markets in order to identify starting dates of systemic financial crises for each country in the panel. Secondly, the selection of early warning indicators for assessment and prediction of systemic risks is undertaken in a two- step approach; relevant prediction horizons for each indicator are found by means of a univariate logit model followed by the application of Bayesian model averaging method to identify the most useful indicators. Next, logit models containing useful indicators only are estimated on the panel while their in-sample and out-of-sample performance is assessed by a variety of measures. Finally, having applied the constructed EWS for both horizons to the Czech Republic it was found that even though models for both horizons perform very well in-sample, i.e. both predict 100% of crises, only the long model attains the maximum utility of 0,5 as...

DSGE models are as structural models capable of estimating what would have happened if some part of economy or shocks to it had been different. We consider three such differences in the recent Czech history: no financial shocks during the crisis in 2008-2009; eurozone membership during the crisis in 2008-2009; and no foreign exchange interventions of the Czech National Bank in November 2013. For this purpose, we employ a small open economy DSGE model with financial frictions and estimate it with Bayesian inference. Our results show that impact of financial shocks on GDP growth was negligible. Further, eurozone membership would have made crisis more severe; GDP growth in 2009Q1 would have been -6% instead of -3% and economy would have been in deflation for the five consecutive periods. Difference is explained by strong depreciation of exchange rate during crisis that would not have occurred with the fixed exchange rate. Lastly, the Czech National Banks's foreign exchange interventions increased GDP growth by as much as 0.8 percentage point and saved economy from deflation in all following quarters. They worked through depreciation of exchange rate and consequent improvement in trade balance and increase in price of imported goods. Powered by TCPDF (www.tcpdf.org)

This thesis examines the bank efficiency and the impact of the regulatory and supervisory instruments on the efficiency of banks actively performing on the financial markets in the countries of European Union. Our analysis concerns 8-year time period, covering also the period of global financial crisis with the aim to determine possible changes in the relationship regulation versus efficiency. We apply SFA Fourier-flexible model for estimation of profit and cost efficiency scores. Consequently we use GLS panel data estimation in order to test for the regulatory determinants of efficiency, we have specified 6 various models with the focus on different regulatory instruments. Results firstly suggest that high cost efficiency does not necessarily imply high bank profit efficiency. Secondly, we uncovered the negative relation between market concentration, the level of development of financial market and the cost efficiency of foreign banks. Thirdly, we also found evidence supporting the assumption of positive impact of private monitoring and the independence of supervisory authority implying the increasing of transparency in the market. Additionally, we uncovered support for negative effect of activity and diversification restrictions. However, the results concerning the financial crisis period are...

The Diploma Thesis deals with the insurance frauds connected to crisis periods, which are due to the longstanding recession and increasingly frequent natural disasters a very hot and current topic. First of all, the insurance fraud is generally defined, including its offenders, possible causes, consequences or regulations, which completely describe given problematics. Then, attention is paid to the contest with insurance frauds, where suggestions for improving the prevention and detection of this crime can be found. The Diploma Thesis also analyzes the current phase and trends in the recent years, and last, but not least, it deals with the relationship between the insurance frauds and specific periods of the crisis.

The thesis analyses and compares the economies of Spain and Ireland in the run up to and during the current economic and financial crisis. Firstly, the focus is on the pre-crisis period since the mid 90's, the causes and extent of the price bubble on the property markets, the caracter of lending boom and the indebtedness of the private sector. The end of the lending boom and conjuncture on the real estate markets in 2006-2007 had strong impact on real economy and the financial sector. Both countries currently pass through a three-level crisis: economic, banking and debt crisis. The aim of the thesis is to examine their causes, evolution and causal links. The paper also illustrates future perspectives of both countries in context of the membership in EMU and possible solutions to their current situation.

This thesis examines characteristics of the economic governance, its levels and changes that were made in response to events in Southeast Asia in 1997/1998. it describes in detail the role of levels of the economic governance during the solution of the asian financial crisis, that exposed its vulnerabilities. In response to the crisis many changes took place. In the region of Southeast Asia these changes were designed to reform the International Monetary Fund, the origin of regional cooperation in the area and reforms in particular countries of the region. The thesis also contains the evaluation of the development of the economic governance in particilar states of Southeast Asia regarding world governance indicators WGI.

The submitted master's thesis analyzes the impact of the global economic crisis on the Czech economy and export of the Czech republic. On the basis of statistical data thesis examines the evolution of basic macroeconomic indicators in the period before the crisis and during an economic downturn, which characterizes the current economy situation in the Czech republic. The work depicts the changes in the state support for exports, the government taken measures and shortcomings in our export policy. The main aim of the work -- in addition to analysis and forecasts of economic developments of the Czech republic -- are recommendations for the creation of New export strategy, evaluation the business environment for Czech export companies, including the main measures to increase competitiveness of the Czech economy.

The purpose of this Master's thesis is divided into two steps. The first step sums up all the relevant theory about financial crises and monetary policies. The second step analyzes not only the past but focuses mainly on the global financial crisis which started in 2007. The cornerstones of this analytical bloc are monetary policies of central banks in China, Venezuela, Denmark and the Czech Republic. Two hypotheses are stated in the beginning of this Master's thesis. These focus on fixed exchange rate regimes and foreign exchange reserves. The analytical part of Master's thesis tries to prove whether these hypotheses can be marked as valid or invalid.
