- This paper offers two general equilibrium notions: Ratio-Lindahl and ratio equilibria, which respectively correspond to a mixed-ownership institutional system and a state-ownership institutional system for any number of private and public goods. These equilibrium notions include Kanekos (1977) ratio equilibrium for economies with only one private good and the conventional Lindahl equilibrium as special cases. The approach we use to prove the existence allows not only for production technologies of state-owned firms to display some kinds of increasing returns to scale, but also provides a simple way to find the ratio-Lindahl equilibrium.
