The same fuels are taxed at widely different rates in different countries while different fuels are taxed at widely different rates within and across countries. Coal, oil and gas are all used to generate electricity, but are subject to very different tax or subsidy regimes. This paper considers...

Concerns over future oil scarcity might not be so worrying but for the high carbon content of substitutes, and the limited capacity of the atmosphere to absorb additional CO2 from burning fuel. The paper argues that the tools of economics are helpful in understanding some of the key issues in...

The six Persian Gulf monarchies are home to some of the world’s largest hydrocarbon reserves, and also some of the cheapest energy prices and highest per-capita consumption. Government subsidies based on socio-political objectives have contributed to regime longevity, but they have also...

This paper examines the impact of an emissions trading scheme (ETS) on equilibrium emissions, output, price, market concentration, and profits in a generalized Cournot model. We develop formulae for the number of emissions permits that have to be freely allocated to firms to neutralize the...

This paper identifies neighbourhood effects in consumption using the randomized nature of the Progresa programme. Recent studies establish that the programme affects the consumption of both eligible and neighbouring ineligible households but the underlying mechanism of the spillovers is not...

We present a model of altruistically-minded-yet rational-players contributing to a public good. A key feature is the tension between altruism and "crowding-out" effects (players' efforts are strategic substitutes). We find that more altruistic behaviour can raise or reduce welfare, depending on...

The aim of this paper is to look at the UK’s renewable energy policy in the context of its overall decarbonisation and energy policies. This will allow us to explore the precise nature of the ‘failure’ of UK renewables policy and to suggest policy changes which might be appropriate in...

This paper investigates interfuel substitution in the UK manufacturing sector. Econometric models of interfuel substitution are applied to energy inputs aggregated by their energy use, and separately for thermal heating processes, where interfuel substitution is technologically feasible....

This paper examines the effects of firm-level innovation in carbonabatement technologies on optimal cap-and-trade schemes with and without price controls. We characterize optimal cap-and-trade regulation with a price cap and price floor, and compare it to the individual cases of pure taxation...

CO2 emission certificates internalise effects of fossil fuel consumption on global climate and sea levels. If they are only implemented in some countries, then their effectiveness is limited; Consumption, production and investment decisions do not reach the optimal allocation, production with...
