The budget set is bounded above by the budget line. Graphically speaking, all the consumption bundles that lie inside and on the budget constraint form the budget set. By most definitions, budget sets must be compact and convex. budget share Engel curve Describes how the proportion of household income spent on a good or service varies with income.
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. [1]
In economics, a budget constraint represents all the combinations of goods and services that a consumer may purchase given current prices within their given income. Consumer theory uses the concepts of a budget constraint and a preference map as tools to examine the parameters of consumer choices .
If Walras's law has been satisfied, the optimal solution of the consumer lies at the point where the budget line and optimal indifference curve intersect, this is called the tangency condition. [3] To find this point, differentiate the utility function with respect to x and y to find the marginal utilities, then divide by the respective prices ...
In economics and particularly in consumer choice theory, the income-consumption curve (also called income expansion path and income offer curve) is a curve in a graph in which the quantities of two goods are plotted on the two axes; the curve is the locus of points showing the consumption bundles chosen at each of various levels of income.
A Robinson Crusoe economy is a simple framework used to study some fundamental issues in economics. [1] It assumes an economy with one consumer, one producer and two goods. The title "Robinson Crusoe" is a reference to the 1719 novel of the same name authored by Daniel Defo
The budget set is bounded above by a -dimensional budget hyperplane characterized by the equation =, which in the two-good case corresponds to the budget line. Graphically, the budget set is the subset of R + k {\displaystyle \mathbb {R} _{+}^{k}} that contains all the consumption bundles that lie on or below the budget hyperplane.
Government deficit spending is a central point of controversy in economics, with prominent economists holding differing views. [3]The mainstream economics position is that deficit spending is desirable and necessary as part of countercyclical fiscal policy, but that there should not be a structural deficit (i.e., permanent deficit): The government should run deficits during recessions to ...
