This paper explores optimal treatment of an SIS (Susceptible-Infected-Susceptible) disease that has two strains with di¤erent infectivities. When we assume that neither eradication nor full infection are possible, it is shown that there are two categories of equilibria. First, there are two...

Solving dynamic models with inequality constraints poses a challenging problem for two major reasons: dynamic programming techniques are reliable but often slow, while Euler equation based methods are fast but have problematic or unknown convergence properties. This paper attempts to bridge this...

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...

There are two difficulties in doing an objective evaluation of the performance of decision-making units (DMUs). The first one is how to treat undesirable outputs jointly produced with the desirable outputs, and the second one is how to treat uncontrollable variables, which often capture the...

We employ a value chain analysis approach to examine the forces shaping the industry structure, entry and inter-firm governance modes. Forty largest global and regional companies in the ethanol manufacturing stage have been classified according to their pre-entry industry of origin. Firms with...

This paper considers the prospects for financing a wave of new nuclear power plants (NPP) using project financing, which is used widely in large capital intensive infrastructure investments, including the power and gas sectors, but has not previously been used for nuclear power. It argues that...

This paper presents results of the 2010 Electricity Policy Research Group (EPRG) public opinion survey. The survey examines the energy policy preferences and attitudes of the British public, the potential for consumer engagement and consumer acceptance of various energy demand response...

The UK Government proposes offering long-term Feed-in-Tariffs (FiTs) to low-carbon generation to reduce risk and encourage new entrants. Their preference is for a Contract-for-Difference (CfD) or a premium FiT (pFiT) for all generation regardless of type. I argue that neither is suitable for...

What would be the effect of CO2 pricing on global oil supply and demand? This paper introduces a model describing the interaction between conventional and non-conventional oil supply in a Hotelling framework and under CO2 constraints. The model assumes that nonconventional crude oil enters the...

The UK and other EU countries are concerned to deliver secure, sustainable and affordable electricity, to meet challenging targets for decarbonisation and renewable energy. The UK Government has consulted and concluded that the present electricity market arrangements will not deliver all three...
