In consumer theory, a consumer's preferences are called homothetic if they can be represented by a utility function which is homogeneous of degree 1. [1]: 146 For example, in an economy with two goods ,, homothetic preferences can be represented by a utility function that has the following property: for every >:
Example: Agricultural products which have many buyers and sellers, selling homogeneous goods where the price is determined by the demand and supply of the market and not individual firms. In the short run, a firm in a perfectly competitive market may gain profits or loss, but in the long run, due to the entry and exit of new firms, price will ...
Goods that require locally abundant inputs are cheaper to produce than those goods that require locally scarce inputs. For example, a country where capital and land are abundant but labor is scarce has a comparative advantage in goods that require lots of capital and land, but little labor — such as grains.
Assume that many firms provide a homogeneous good. Consumers will randomly sample only one firm if they expect that all firms charge the same price. Consequently, each firm has an equal share of consumers. Since consumers disregard the competitions, each firm acts as a monopoly on its share of consumers.
In microeconomics, the expenditure function gives the minimum amount of money an individual needs to spend to achieve some level of utility, given a utility function and the prices of the available goods. Formally, if there is a utility function that describes preferences over n commodities, the expenditure function
The theory of consumer choice is the branch of microeconomics that relates preferences to consumption expenditures and to consumer demand curves.It analyzes how consumers maximize the desirability of their consumption (as measured by their preferences subject to limitations on their expenditures), by maximizing utility subject to a consumer budget constraint.

A good in economics is any object, service or right that increases utility, directly or indirectly. A good that cannot be used by consumers directly, such as an "office building" or "capital equipment", can also be referred to as a good as an indirect source of utility through resale value or as a source of income.
In economics, goods are items that satisfy human wants [1] and provide utility, for example, to a consumer making a purchase of a satisfying product. [2] Economics focuses on the study of economic goods , or goods that are scarce ; in other words, producing the good requires expending effort or resources.
