1, microeconomics is an economic theory that studies the economic behavior of a single economic unit in society and how to determine the individual value of the corresponding economic variables; Analyze the economic behavior of individual economic units, on this basis, study the operation of market mechanism and its role in the allocation of economic resources in modern western economic society, and put forward microeconomic policies to correct market failure; Paying attention to the exchange process between individuals and organizations in society, its basic problem is the decision of resource allocation, and its basic theory is the theory of determining relative prices through supply and demand. Therefore, the main scope of microeconomics includes consumer choice, supplier supply and income distribution.

2. Utility function is usually used to express the quantitative relationship between the utility obtained by consumers in consumption and the commodity combination they consume, so as to measure the satisfaction of consumers from a given commodity combination. The definition of utility function is, let F be the preference relation defined on the consumption set X. If any x, y, xfy and u (x) in X is ≥ u (y), then the function u:X→R is the utility function representing the preference relation F.

Interpretation of "Utility Function" in Tool Books

1, which represents the function of the quantitative relationship between the utility obtained by consumers in consumption and the commodity combination consumed. It is used to measure consumers' satisfaction from consuming a specific combination of goods. Using indifference curve can only analyze the combination of two commodities, while using utility function can analyze the combination of more commodities. The expression is: U=U(x, y, z,) where x, y, z respectively represent the quantity of various commodities owned or consumed by consumers, the u on the left side of the formula is ..... "Utility function" is explained in academic literature, and F(X) is called utility function. The key of weighted P norm method is to determine the weight coefficient. There are two basic types.

2. A person's utility should be a function of wealth X, which is called utility function. Theoretically, we can approach everyone's utility function through a series of psychological tests. Different decision makers should have different utility functions. First of all, we seek the properties satisfied by utility function or some special types of utility function.

3. This is a theoretical assumption, and the model they built with mathematical function is called "utility function". According to this model, people can be assumed to be able to decide the choice to produce a certain degree of benefits and pursue the maximization of benefits in every possible time allocation.
