The IS curve moves to the right if spending plans at any potential interest rate go up, causing the new equilibrium to have higher interest rates (i) and expansion in the "real" economy (real GDP, or Y). In most mathematical contexts, the independent variable is placed on the horizontal axis and the dependent variable on the vertical axis.
First, the AD (blue) curve is positive. The AD curve is assumed to be positive because an increase in national output should lead to an increase in disposable income and, thus, an increase in consumption, which makes up a portion of aggregate demand. [5] Second, the AD curve is assumed to have a positive, vertical intercept.
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.
The LM curve shows the combinations of interest rates and levels of real income for which the money market is in equilibrium. It shows where money demand equals money supply. For the LM curve, the independent variable is income and the dependent variable is the interest rate.
The AD–IA model is a Keynesian method used to explain economic fluctuations. This model is used to show undergraduate students how shifts in demand or shocks to prices can affect real GDP around potential. The model assumes that when inflation rises the interest rate rises (monetary policy rule).
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.
Basic diagram of the circular flow of income. The functioning of the free-market economic system is represented with firms and households and interaction back and forth. [2] The circular flow of income or circular flow is a model of the economy in which the major exchanges are represented as flows of money, goods and services, etc. between ...
The traditional LM curve is upward sloping because the interest rate and output have a positive relationship in the money market: as income (identically equal to output in a closed economy) increases, the demand for money increases, resulting in a rise in the interest rate in order to just offset the incipient rise in money demand.
