Description

Municipal infrastructure companies are facing major challenges. On the one hand, these companies are operating under an increased pressure to reduce costs with intensive competitive and regulatory pressures. On the other hand, they face new energy and climate policy objectives and have to fulfill new requirements because of the  demographic change. Recent privatizations have not always realized the expected cost saving. New approaches and solutions are needed. However, there is a lack of theory-based empirical analyzes assessing the effects of different company organizations on efficiency, cost reduction potentials, or consumer prices. Creating a unique firm level panel data set of energy, water and waste management companies allows for a comprehensive analysis for Germany. An innovative and multidimensional framework, which explicitly models the particular decision making behavior of municipal infrastructure companies, examines modernization and restructuring processes under new climate policy and demographic requirements.
