Published / Preprint: Nash equilibrium for coupling of CO2 allowances and electricity markets. (arXiv:1311.1535v1 [q-fin.TR])

Posted: 07 Nov 2013 05:37 PM PST

In this note, we present an existence result of a Nash equilibrium between electricity producers selling their production on an electricity market and buying CO2 emission allowances on an auction carbon market. The producers' strategies integrate the coupling of the two markets via the cost functions of the electricity production. We set out a clear Nash equilibrium that can be used to compute...

Published / Preprint: Stationary Markov Perfect Equilibria in Discounted Stochastic Games. (arXiv:1311.1562v1 [math.OC])

Posted: 07 Nov 2013 05:37 PM PST

The existence of stationary Markov perfect equilibria in stochastic games is shown in several contexts under a general condition called "coarser transition kernels". These results include various earlier existence results on correlated equilibria, noisy stochastic games, stochastic games with mixtures of constant transition kernels as special cases. The minimality of the condition is illustrated....

This survey reviews portfolio choice in settings where investment opportunities are stochastic due to, e.g., stochastic volatility or return predictability. It is explained how to heuristically compute candidate optimal portfolios using tools from stochastic control, and how to rigorously verify their optimality by means of convex duality. Special emphasis is placed on long-horizon asymptotics,...
