In the course of the deregulation of the telecommunication and energy sector new price regulation mechanisms were introduced to cap the access price to the respective transportation grid. While products and services are supplied under competitive market conditions the transportation girds...

This paper develops an analytical framework for studying the Baumol-Oates efficiency of traditional single instrument abatement policies vis-a-vis green defaults in the face of price inertia and deliberate defaulting of subpopulations. In this special case of behavioural heterogeneity command...

This paper analyzes a modified yardstick competition mechanism (MYC), where the yardstick employed consists of a tariff basket and total costs. This mechanism has a significant information advantage: the regulator ?only? needs to observe total costs and output of all firms. The modified...

We analyze the properties of progressive water tariffs that are often applied in the sector in the form of discretely increasing block tariffs (IBT). We are particularly interested in water tarification in a poverty context where a subsistence level of water has to be allocated to each...

One focus of the G20 Summit in Hamburg in July 2017 was the United Nations' sustainable development goals, including those set for the water sector. Despite progress, around 800 million people worldwide do not have adequate access to drinking water. Increasing block tariffs are an instrument...

This paper analyzes a modified yardstick competition mechanism (MYC), where the yardstick employed consists of a tariff basket and total costs. This mechanism has a significant information advantage: the regulator ”only” needs to observe total costs and output of all firms. The modified...
