The aim of this thesis is to compile a glossary of technical terms relevant to stock exchange mergers and alliances. Since technical communication can only be described meaningfully in the context of technical information, technical knowledge, and terminology, judgmental analysis will be applied to the literature on stock exchange mergers and alliances to identify management theories that are able to explain stock exchange mergers and alliances. One aim is to find out which general theories on mergers and alliances have a high explanatory value for stock exchange cooperation. In the first part of the thesis, the stock exchange world is examined. First a general overview of the theory of corporate growth is given next the changes in the environment of stock exchanges are examined. In the analytical part, fourteen general management theories are applied to stock exchange cooperation. The criteria used to identify the explanatory value of the different theories are the critical success factors of stock exchanges identified in the first part of the thesis. A point system is introduced in order to make the results of the analysis of the different theories more comparable. The final part of the paper consists of an English-German glossary containing the relevant technical terms of stock exchange mergers and alliances. (author's abstract
