In this process, the determination of prices assumes a prominent role. As in the relevant network industries capital costs account for the largest share of total costs, this book addresses a central issue of (de-)regulation. At the same time, a change in the concepts of cost accounting from a traditional, operation-based view, to a more market-based view can be observed in Germany. These trends form the background for the analysis contained in this book. Burkhard Pedell develops a comprehensive concept for the study of regulatory risk and its implications for cost-orientated rate regulation that is founded in state-of-the-art economic research. The concept includes the major variables of regulation that are relevant to the risk (adjusted cost of capital) of rate-regulated firms and investigates the interdependences between them. Central problems such as the circularity between regulation and investors’ expectations, the commitment of the regulator, the employed depreciation methods and their connection to the interest rate, the determination of the regulatory rate ba
