Needing to know what we need
A market economy is designed to meet needs so that resources are efficiently used and utility is maximised, but how do we know what we need? In a world where some societies suffer from consumption-related “status anxiety” while in others people die from starvation it is difficult to find empirical justification for the theoretical position that markets ensure allocative efficiency. The environmental crisis adds an extra dimension to this question: as a closed system the earth has finite resources and a limited capacity to absorb the waste products of industrial society.
