This paper explores the idea that a properly designed sectoral approach could be the answer to two sets of constraints that hinder international agreements on climate change, namely a genuine concern from developing countries for economic growth and competitiveness issues from industrialized...

This paper analyzes the choice of a technology portfolio by risk-averse firms. Two technologies with random marginal costs are available to produce a homogeneous good. If the risks that are associated with the technologies are correlated, then the firms might invest in a technology with a...

Demand uncertainty is thought to in uence irreversible capacity decisions. Suppose local demand can be sourced from domestic (rigid) production or from (fl exible) imports. This paper shows that the optimal domestic capacity is either increasing or decreasing with demand uncertainty depending on...

The optimal timing, sectoral distribution, and cost of greenhouse gas emission reductions is different when abatement is obtained though abatement expenditures chosen along an abatement cost curve, or through investment in low-carbon capital. In the latter framework, optimal investment costs...

Competitiveness and carbon leakage are major concerns for the design of CO2 emissions permits markets. In absence of a global carbon tax and of border carbon adjustments, output based allocation is a third best solution and is actually implemented (Australia, California, New Zealand). The EU has...

Output-based allocations (OBAs) are typically used in emission trading schemes to mitigate leakage in sectors at risk. Recent work has shown they may also help to stabilize prices in markets subject to supply and demand shocks. We extend previous work to simultaneously include both leakage and...

The transition of a sector from a pollutant state to a clean one is studied. A green technology, subject to learning-by-doing, progressively replaces an old one. The notion of abatement cost in this dynamic context is fully characterized. The theoretical, dynamic optimization, perspective is...

Two main approaches have been implemented in regional CO2 markets to address competitiveness and carbon leakage: output based allocation (Australia, California, New Zealand) and capacity based allocation (EU). This paper characterizes the best policy, given that auctioning with border adjustment...

For carbon-intensive, internationally-traded industrial goods, a unilateral increase in the domestic CO2 price may result in the reduction of the domestic production but an increase of imports. In such sectors as electricity, cement or steel, the trade flows result more from short-term regional...
