This chapter explores power sharing as an institutional means of ending conflict. Power sharing is presumably able to address the credible commitment problem and accommodate societal diversity, thus improving the sustainability of peace deals. The chapter discusses two approaches to sharing power: autonomy (associated with efforts to manage diversity) and consociation (linked to attempts to overcome the credible commitment problem). The chapter then turns to concerns about the use of power sharing as a tool of peace-making. Critics of autonomy argue that autonomous institutions are the first step on the road to secession, whereas critics of consociationalism contend that, while it may secure peace, it prevents the achievement of democracy. The chapter concludes that, if it is to fulfil the promise of delivering peace and democracy, power sharing must be adapted to context, flexible enough to accommodate change and designed in such a way as to address its blinders and limitations.
