Diese Dissertation besteht aus drei unabhängigen Kapiteln über mikroökonomische Themen. Die ersten beiden Kapitel befassen sich mit Themen der Industriökonomie und Wettbewerbstheorie, wohingegen das dritte Kapitel Fragestellungen von Cheap Talk Spielen untersucht. Kapitel 1 untersucht die Folgen, die sich aus einer partiellen Akquisition zwischen Wettbewerbern ergeben. Kapitel 2 analysiert die Auswirkungen einer Forschungs-und Entwicklungs (FuE)- Kooperation auf die Investitionsanreize in einem Markt, in dem eine Mehrproduktunternehmer mit einem Einzelproduktuntfirma konkurriert. Kapitel 3 untersucht die Funktion der Mediation zur Erleichterung der Kommunikation mit privaten Informationen. / This dissertation consists of three independent chapters in the field of microeconomics. The first two chapters are concerned with topics of industrial organization and competition policy, whereas the third chapter addresses some problems in cheap talk games. Chapter 1 studies anti-competitive issues that arise from partial acquisition between competitors. Chapter 2 analyzes the effects of cooperation on R&D investment incentives in a market where a multi-product firm competes with a single-product firm. The third chapter examines the role of mediation in facilitating communication with private information.

Fiber-deployment of future telecommunications networks ("Next Generation Access" - NGA) is currently a major challenge for sector-specific regulators as well as for investing firms. Although the future socio-economic importance of new telecommunications networks is uncontroversial, the related investment activities vary substantially in international comparison. This work intends to identify the most important determinants of previous NGA deployment using data from the EU27 member states for the years 2005 to 2010. For our analysis, we employ latest data on NGA deployment, relevant competition and regulatory indicators as well as other supply and demand side controls. Our econometric model incorporates: i) aggregated country level data; ii) structurally modeled dynamics of the deployment process which allows us to disentangle long-term and short-term effects; finally, iii) we argue that there is no endogeneity problem with respect to investment activities and regulation since we refer to regulation in preceding broadband markets. For our econometric analysis, we employ several dynamic panel data methods, such as GMM and LSDVC. Our results indicate that stricter previous broadband access regulation has a negative impact on NGA deployment. As regards the dynamics of the adjustment process, we find that there are severe adjustment costs and stickiness towards the desired long-term level of NGA infrastructure.
