"The Efficient Society" by Joseph Heath discusses the nature of a moral economy in these terms, and argues that Canada has achieved the proper balance between social needs and economic freedom, and as such comes close to being a moral economy. Other economists such as John P. Powelson relate the concept of a "moral economy" to the balance of economic power; in their view, a moral economy is an economy in which economic factors are balanced against ethical norms in the name of social justice.
