We simulate energy policies under alternative regulatory assumptions. We shows that market liberalisation affects the links between generation costs and user prices. We show that the coupling mechanisms should reflect the nature of electricity market regulation. We show that a tax on electricity is more effective in a liberalized than in a regulated market.electricity market regulationpolicy effectivenesstop-down modelbottom-up modelsoft-link couplingtext::working paper
