Potable water supply in Germany is highly fragmented. A consolidation of the industry could, therefore, lead to lower cost of water supply and price savings for the customers. In this paper we estimate a total cost function for potable water supply based on a unique sample of German water utilities observed between 2004 and 2010. Newly available data allows for a detailed cost modeling approach. Capital ...

In this study, we analyze a client’s choice of contract in auctions where Dutch law firms compete for cases. The distinguishing feature is that lawyers may submit bids with any fee arrangement they wish. We find robust evidence that bids offering hourly rates are less attractive to clients. Our findings tentatively contradict lawyers’ often-made argument that hourly rates are in a client’s best in ...

We analyze the pass-through of cost changes to retail tariffs in the German electricity market over the 2007 to 2014 period. We find an average pass-through rate of around 60%, which significantly varies with demand factors: while the pass-through rate to baseline tariffs, where firms have higher market power, is only 50%, it increases to 70% in the competitive segment of the market. Although the pass-through ...

Energy sectors—primarily power generation and gas production, but also energy transmission and distribution—require significant capital investment in infrastructure. Market structures as well as the degree of competition and regulation are key factors that determine firms’ incentive to invest. Yet the empirical research on the link between these factors and private investment is still quite scarce, ...
