Current methods of disseminating scholarly information focus on the use of journals who retain exclusive rights in the material they publish. Using a simple model we explore the reasons for the development of the traditional journal model, why it is no longer efficient and how it could be...

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 mathematical formulation of a large-scale equilibrium natural gas simulation model is presented. Although large-scale natural gas models have been developed and used for energy security and policy analysis quite extensively (e.g., Holz (2007), Egging et al. (2008), Holz et al. (2009) and...

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...

Agent-based modelling is an attractive way of finding equilibria in complex problems involving strategic behaviour, particularly in electricity markets with transmission constraints. However, while it may be possible to demonstrate convergence of learning behaviour to a Nash equilibrium, that is...

We demonstrate how suppliers can take strategic speculative positions in derivatives markets to soften competition in the spot market. In our game, suppliers first choose a portfolio of call options and then compete with supply functions. In equilibrium firms sell forward contracts and buy call...

Wholesale electricity markets use different market designs to handle congestion in the transmission network. We compare nodal, zonal and discriminatory pricing in general networks with transmission constraints and loop flows. We conclude that in large games with many producers who are allowed to...

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 unquantifed - impact on market performance. With n symmetric firms, equilibrium welfare...

This study contributes to the literature on estimating market power in homogenous product markets. We estimate a composed error model, where the stochastic part of the firm’s pricing equation is formed by two random variables: the traditional error term, capturing random shocks, and a random...

Recent industry studies found the Internet backbone industry competitive. In our paper we explore a novel route to monitor for market power using prices and quality data from Band-X. First we test the hypothesis that Europe is a connectivity market on its own, unchallenged by the US and then, by...
