We examine the largest cost component in offshore development projects, drilling rates, which have been high in recent years. To our knowledge, rig rates have not been analysed empirically before in the economic literature. Using econometric analysis, we examine the effects of gas and oil...

Several European countries have decided to phase out coal power generation. Emissions from electricity generation are already regulated by the EU Emissions Trading System (ETS), and in some countries like Germany the phaseout of coal will be accompanied with cancellation of emissions allowances....

What factors determine whether it is optimal with one or more technologies in a decarbonized road transport sector, and what policies should governments choose? We investigate these questions theoretically and numerically through a static, partial equilibrium model for the road transport market....

For any emission trading system (ETS) with quantity-based endogenous supply of allowances, there exists a negative demand shock, e.g. induced by abatement policy, that increases aggregate supply and thus cumulative emissions. We prove this green paradox for a general model and then apply it to...

With the new rules of the EU ETS, involving cancellation of allowances, cumulative emissions are no longer fixed but depending on the market outcome. Perino (2018) showed that additional abatement effort can reduce cumulative emissions if it occurs within a few years. This article shows that...

Policy makers in the EU and elsewhere are concerned that unilateral carbon pricing induces carbon leakage through relocation of emission-intensive and trade-exposed industries to other regions. A common measure to mitigate such leakage is to combine an emission trading system (ETS) with...

Abatement can be performed by measures that have an impact on present emissions, but no lasting effect, and by long-lived infrastructure investments. We study the optimal combination of short and long-lived options for reducing greenhouse gas (GHG) emissions, by specifying abatement cost...

Following the Brent Spar controversy, the OSPAR countries reached a unanimous agreement in 1998 for the future rules for disposal of petroleum installations. The vast majority of existing offshore installations will be re-used or returned to shore for recycling or disposal. For installations...

Two jurisdictions compete to capture the rents of a large multinational enterprise (MNE) which invests locally and which is partly owned by local investors. The MNE contributes to local welfare by tax payments and dividends, and it has private information about the efficiency of the operations...

Gas exports to the Continent are regulated by long term take-or-pay contracts. The contracts are described and analyzed. We thereafter examine whether the most central European gas market, the German market, is integrated. Are there substantial price differences between gas from different export...
