The Appetiser suggests that the neoclassical economic model responds to a conjecture regarding the relationship between private and public interest rather than a question about the working of economic exchange. The Starter explains economic exchange. To explain economic exchange, it is first necessary to explain the process of ‘support-bargaining’ and the creation of money. With that, it is possible to explain how money is used in ‘money-bargaining’, the process of economic exchange. The Appetiser also identifies ‘communal interests’ as outcomes of support-bargaining. Money-bargaining accommodates communal interests as well as the individual interests that are the basic concern of neoclassical theory.
