  • Dany Ralph (University of Cambridge) "Risk aversion in capacity equilibria", joint work with Yves Smeers (Université de Louvain)

We look at risk averse electricity generation companies that investing in both new plants and financial products to reduce their risk, where the value (cost of operation) of plants is optimized in each of many (stochastic) spot market scenarios. This results in an investment or capacity equilibrium problem of risk averse agents . Assuming completeness of the risk market, we can reduce a capacity equilibrium between N risk averse firms to a _risk neutral_ Nash game between the same N firms plus an N+1st agent that prices risk. This gives existence of an equilibrium when there are only finitely many spot market scenarios. Time permitting we will discuss existence of an equilibrium when an Lp-space represents random or uncertain vectors.
