While the link between the ownership and productive efficiency of firms has been discussed extensively, no consensus exists regarding the superiority of one or the other in non-competitive, regulated environments. This paper applies a flexible production model to test for efficiency differences...

We analyze the effects of an incentive based regulatory scheme with revenue caps on the investment behaviors and decisions of 109 electricity distribution companies operating in Germany in 2006-2012. We hypothesize that Germany's implementation of incentive regulation in 2009 has a negative...

We discuss the implications of two price zones, i.e. one northern and southern bidding area, on the German electricity market. In the northern zone, continuous capacity additions with low variable costs cause large regional supply surpluses in the market dispatch while conventional capacity...

Natural gas prices in Germany saw a strong increase at the end of 2021, subsequently worsening with the start of the war in Ukraine in February 2022, raising concerns about the distributional consequences. Our study shows that low-income households are affected the most by the natural gas price...

The liberalisation of the natural gas markets and the importance of natural gas as a transition fuel to a low-carbon economy have led to the development of several large-scale equilibrium models in the last decade. These models combine long-term market equilibria and investments in...

US shale gas production is generally expected to continue its fast rise. However, a cautious evaluation is needed. Shale gas resource estimates are potentially overoptimistic and it is uncertain to which extent they can be produced economically. Moreover, the adverse environmental effects of...

In 1997, the Comisión Reguladora de Energía of Mexico implemented a netback rule for linking the Mexican natural gas price to the Texas price. At the time, the Texas price reflected a reasonably competitive market. Since that time, there have been dramatic increases in the demand for natural...

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...

Sub-Saharan Africa ranks among the top regions in terms of growth in the number of mobile phone users. The success of mobile telephony is attributed to the opening of markets for private players and lenient regulatory policy. However, markets may be increasingly saturated and new regulations...
