White certificate obligations impose energy savings targets on energy companies and allow them to trade energy savings certificates. They can be seen as a means of internalizing energy-use externalities and addressing energy efficiency market failures. This paper reviews existing evaluations of...

We investigate how moral hazard problems can cause sub-optimal investment in energy efficiency, a phenomenon known as the energy efficiency gap. We argue that such problems are likely to be important for home energy retrofits, where both the seller and the buyer can take hidden actions. The...

Climate change mitigation requires to replace preexisting carbon-intensive capital with different types of cleaner capital. Coal power and inefficient thermal engines may be phased out by gas power and efficient thermal engines or by renewable power and electric vehicles. We derive the optimal...

Although the building sector is recognized as having major potential for energy conservation and carbon dioxide emissions mitigation, conventional bottom-up and top-down models are limited in their ability to capture the complex economic and technological dynamics of the sector. This paper...

The European Union Emissions Trading System (EU-ETS), presented as the ''flagship'' of European climate policy, is subject to many criticisms from different stakeholders. Criticisms include the insufficient carbon emissions reduction, the competitiveness losses and the induced carbon leakages,...

This article constitutes a new contribution to the analysis of overlapping instruments to cover the same emission sources. Using both an analytical and a numerical model, we show that when the risk that the CO2 price drops to zero and the political unavailability of a CO2 tax (at least in the...

We study the impact on employment in France of the implementation of the energy transition scenario built by négaWatt (2011), which provides a massive development of energy savings (through measures of sufficiency and energy efficiency) and renewable energy between 2012 and 2050. Compared to...

The EU ETS has been criticised for threatening the competitiveness of European industry and generating carbon leakage, i.e. increasing foreign greenhouse gas emissions. Two main options have been put forward to tackle these concerns : border adjustments and output-based allocation, i.e....

In a dynamic (sequential) framework, departures from the independence axiom (IND) are reputed to induce violations of dynamic consistency (DC), which may in turn have undesirable normative consequences. This result thus questions the normative acceptability of non expected-utility (non-EU)...

In the Sudano-Sahelian region, which includes South Niger, the inter-annual variability of the rainy season is high and irrigation is scarce. As a consequence, bad rainy seasons have a massive impact on crop yield and regularly entail food crises. Traditional insurances based on crop damage...
