By Andrew Cumbers for The Next System Project - This paper advocates a form of economic democracy based around diverse forms of public ownership. It does not prioritize one particular scale but recognizes the importance of decentralized forms of public ownership, to encourage greater public participation and engagement, mixed with higher level state ownership, for strategic sectors and planning for key public policy goals (e.g. tackling climate change). It takes a deliberately pluralistic definition of public ownership, recognizing both state ownership and the role that cooperatives and employee ownership could play in a more democratic economy. The main aim of the proposal outlined here is to enhance democratic participation and collective knowledge formation in relation to the economy. The paper outlined is premised on the principal that increased privatization of the economy is leading to growing inequalities, inappropriate policy formation, and decision-making in the interest of wealthy elites at the expense of a broader common good. In contrast, there is considerable evidence that greater collective ownership of the economy will lead to more progressive, egalitarian, and socially just outcomes that also offer more effective solutions to critical public policy problems, such as dealing with the effects of climate change.
