Preference Modelling

Preference modelling is the formal representation and analysis of how individuals or agents rank, evaluate, or choose among a set of alternatives. It seeks to capture the decision-maker’s subjective tastes, priorities, and trade-offs by defining mathematical structures—such as preference relations and utility functions—that reflect their ordering of options. This modelling enables predictions of choice behavior under certainty or uncertainty, facilitates comparison of alternatives, and forms the foundation for economic analysis, game theory, and decision theory.

Marginalism is an economic theory that analyzes how individuals make decisions based on the additional (marginal) benefit or cost of a small incremental change in the consumption or production of goods and services.

Marginalism is about incremental changes (absolute units).

Technically, the marginalist revolution is defined by a new method of economic analysis which applies the calculus to the problem of the determination of prices.

Marginal utility is the additional satisfaction or benefit that a consumer derives from consuming an additional unit of a good or service.
