This paper presents a game-theoretic analysis of multimarket competition with capacity investments, applied to international gas markets. It identifies a strategic advantage of «focused» pipeline gas producers (e.g., Gazprom) over «diversified» multimarket exporters of liquefied natural gas...

Transport constraints limit competition and arbitrageurs' possibilities of exploiting price differences between commodities in neighbouring markets. We analyze a transportation network where oligopoly producers compete with supply functions under uncertain demand, as in wholesale electricity...

This paper is an extension of the paper 'The Robustness of Agent-Based Models of Electricity Wholesale Markets', EPRG1213 which was motivated by the problem of analysing market power in liberalised electricity markets. That paper examined two particular forms of agent-based models commonly used...

Corporate managers and executive compensation in many industries place significant emphasis on measures of firm size, such as sales revenue or market share. Such objectives have an important yet thus far unquantified impact on market performance. With n symmetric firms, equilibrium welfare...

The traditional measure of market power is the HHI, which gives implausible results given the low elasticity of demand in electricity spot markets, unless it is adapted to take account of contracting. In its place the Residual Supply Index has been proposed as a more suitable index to measure...

This paper uses a bi-level game to model markets for delivery of electrical power on looped transmission networks. It analyzes the effectiveness of an independent system operator (ISO) when generators (and, in some cases, retailers) with market power bid a single parameter of their linear supply...

This paper analyses the economics of long-term gas contracts under changing institutional conditions, mainly gas sector liberalisation. The paper is motivated by the increasingly tense debate in continental Europe, UK and the US on the security of long-term gas supply. We discuss the main issues...

The paper surveys the literature and publicly available information on market power monitoring in electricity wholesale markets. After briefly reviewing definitions, strategies and methods of mitigating market power we examine the various methods of detecting market power that have been employed...

Numerical models for electricity markets are frequently used to inform and support decisions. How robust are the results? Three research groups used the same, realistic data set for generators, demand and transmission network as input for their numerical models. The results coincide when...

Privatisation of utilities is about ownership rather than control. Liberalisation can induce greather improvements in performance than privatisation alone. Regulation id inevitably inefficient, and adequately competitive network services may improve efficiency. History indicates that regulated...
