The first chapter summarises basic characteristics of the export credit insurance, particularly focusing on the export credit insurance with state support. The second chapter summarises the issue of export credit insurance as a tool of export-oriented politics. The third one describes international organisations and international regulations affecting export credit insurance with state support. Tha last chapter summarises developement of export credit insurance from the beginning to the present time including contemporary economic crisis.

Le présent mémoire présente d'une part la recherche dans l'expérience L3 au LEP de particules supersymétriques, les leptons scalaires, dans deux topologies distinctes : " électron + X + Ebaré " et " 2 leptons + 2 photons + Ebaré ", lesquelles correspondent à deux cadres théoriques supersymétriques qui sont respectivement m-SUGRA et GMSB. D'autre part le travail a été complèté par<br />l'étude du calorimètre électromagnétique à cristaux de BGO de L3, et la calibration du calorimètre<br />électromagnétique EGAP. Après une revue des motivations essentielles pour la Supersymétrie sont<br />détaillés les modes de production et de désintégration des leptons scalaires à LEP. Après avoir<br />présenté les outils d'analyse utilisés, sont détaillés les résultats obtenus à partir des données collectées par L3 à des énergies au centre-de-masse comprises entre 183 GeV et 202 GeV. Les<br />critères de sélections permettant d'isoler les événements que l'on recherche, et les efficacités ainsi<br />que les taux de bruit de fond en provenance du Modèle Standard auxquels on peut s'attendre<br />sont présentés. L'interprétation des résultats des recherches dans les deux cadres m-SUGRA et<br />GMSB font l'objet d'un cinquième chapitre. On a pu en tirer des limites inférieures sur les masses<br />des leptons scalaires qui ne dépendent pas des paramètres libres du modèle supersymétrique, en<br />particulier sur la masse du sélectron dans le cadre de m-SUGRA qui est :<br />M > 71:2 GeV

The main aim of this thesis is to analyze the brewery Poutník in terms of its foreign trade and possibilities for entering foreign markets. The first part provides the theoretical knowledge of foreign trade, forms of entry into foreign markets and possibilities of export support in the Czech Republic. In the main part there is a characteristic of the brewery Poutník, this part also contains the PEST analysis, the portfolio analysis, the characteristic of selected economic indicators and the SWOT analysis that is form of these analysis. The analysis of potential foreign markets is used in the next part. There are 3 selected states: Slovenia, Italy, Romania. The PEST analysis and the portfolio analysis are provided for each state. Possibilities of export support from the CzechTrade agency, Czech export bank and EGAP are also chosen. At the end of the thesis it was suggested suitable options of the entry to these markets.

For such a small open economy as is the case of the Czech Republic, export is one of the key growth factors. Further, small and medium sized enterprises are very efficient tool of the economic stability. Government should therefore analyse and fulfil export needs of those entrepreneurs. There is actually no questin about importance of government assistance. Most of the developed countries already help their small and medium enterprises. Ignoring this fact could lead to the reduction of the competitive strength of Czech companies. The diploma thesis analyses the export needs of those firms and compares them with the government assistance programs. Theoretical part is focused on definition of this entrepreneur's category, describes assistance frame and analyses the influence of export on the Czech economy. Practical part deals with individual export assistance programs and analyses the export needs of Czech exporters based on several surveys. The last part of the diploma thesis compares the Czech government assistance with the assistance that foreign countries provide their entrepreneurs with. The final recommendations regarding the possibilities of increase in the efficiency of the government assistence are included in the last chapter.

This thesis provides an overview of the importance of exports for the Czech economy and the main instruments used for support of exports by state and private institutions. It also presents new export activities of a non-state institution - International Chamber of Commerce in the Czech Republic (ICC Czech Republic), which is the general public not sufficiently aware of. The work contains opinions and positions of entities being directly affected by state export promotion in the Czech Republic - particularly small and medium enterprises, large exporters, and commercial banks - and also their specific requirements for the content of state export strategy. Their opinions are derived from various surveys and analysis and based on the information obtained from ICC Czech Republic. To create high-quality export strategy, it is necessary for the Ministry of Industry and Trade to cooperate with all relevant subjects such as EGAP, Czech Export Bank, Czech Chamber of Commerce, ICC Czech Republic, but especially with the business community. The strategy also needs to include the consolidation of state export promotion services, the allocation of sufficient funds for the Czech Export Bank and EGAP, the involvement of commercial banks in foreign trade finance and enhancement of international competitiveness of Czech exports. Thus can only be increased its contribution to individual subjects of foreign trade and the State itself.
