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.
The latter concept involves a single provider charging different prices to different customers for an identical good. Price dispersion, on the other hand, is best thought of as the outcome of many firms potentially charging different prices, where customers of one firm find it difficult to patronize (or are perhaps unaware of) other firms due ...
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
An example is the abstraction of a composite good. It considers the price of one good changing proportionately to the composite good, that is, all other goods. If this assumption is violated and the agents are subject to aggregated utility functions, restrictions on the latter are necessary to yield the law of demand. The aggregation problem ...
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.
