We provide the description and illustrative results of the World Gas Model, a multi-period complementarity model for the global natural gas market. Market players include producers, traders, pipeline and storage operators, LNG liquefiers and regasifiers as well as marketers. The model data set...

We apply the EMF 23 study design to simulate the effects of the reference case and the scenarios to European natural gas supplies to 2025. We use GASMOD, a strategic several-layer model of European gas supply, consisting of upstream natural gas producers, traders in each consuming European...

The paper deals with the competitive effects of price guarantees in a spatial duopoly where consumers can search for lower prices but have to incur hassle costs if they want to claim a price guarantee. It is shown that symmetric equilibria with and without price guarantees exist but price...

We address investment in regulated natural gas pipelines when investment is lumpy and the demand for gas is stochastic. This is a problem that can be solved in theory as a dynamic program, but a practical solution depends on functions and parameters that are either subjective or cannot be...

Nonparametric efficiency analysis has become a widely applied technique to support industrial benchmarking as well as a variety of incentive- based regulation policies. In practice such exercises are often plagued by incomplete knowledge about the correct specifications of inputs and outputs....

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...

This paper provides an empirical demonstration for a practical approach of efficiency evaluation against the background of limited data availability in some regulated industries. Here, traditional DEA may result in a lack of discriminatory power when high numbers of variables but only limited...

The interdependence of electricity and natural gas is becoming a major energy policy and regulatory issue in all jurisdictions around the world. The increased role of gas fired plants in renewable-based electricity markets and the dependence on gas imports make this issue particular striking for...

Many developing countries around the world apply progressive water tariffs, often structured in the form of discretely increasing block tariffs (IBTs). These tariffs have been criticized in the welfare economic literature due to their perceived inefficiency: many of the prices charged under IBTs...
