This article analyzes the modelling of risk premia in CO2 allowances spot and futures prices, valid for compliance under the EU Emissions Trading Scheme (EU ETS). Similarly to electricity markets, a salient characteristic of CO2 allowances is that the theory of storage does not hold, as CO2...

When rates of return on bonds are computed over extremely short holding periods, the ex post cross-sectional relationship between realized return and risk is linear. It is therefore possible, at any time, to extrapolate the cross-sectional relationship to a zero risk level, and thus to determine...

Our study investigates by which channels IPO underpricing impacts post-listing liquidity. Using a sample of IPOs undertaken on Euronext with diverse mechanisms, we show that when ownership structure is not influenced by initial underpricing, this underpricing still has a positive impact on...

This paper analyzes the special features of electricity spot prices derived from the physics of this commodity and from the economics of supply and demand in a market pool. Besides mean-reversion, a property they share with other commodities, power prices exhibit the unique feature of spikes in...
