The PES0 model, also known as the “Pay-Equal-Share-Of-Zero” model, is a concept used in economics to describe a system where all individuals or entities involved in a transaction contribute an equal amount, regardless of their initial wealth or resources. This model promotes fairness and equal distribution of resources, as it ensures that no one party bears a disproportionate burden. It is often used in discussions of taxation and resource allocation, and has gained popularity in recent years as a potential solution to income inequality.
