A curve may have equivalent parametrizations when there is a continuous increasing monotonic function relating the parameter of one curve to the parameter of the other. When there is a decreasing continuous function relating the parameters, then the parametric representations are opposite and the orientation of the curve is reversed. [1] [2]
This graph shows supply and demand as opposing curves, and the intersection between those curves determines the equilibrium price. An alteration of either supply or demand is shown by displacing the curve to either the left (a decrease in quantity demanded or supplied) or to the right (an increase in quantity demanded or supplied); this shift ...
The MP curve displays a positive relationship, upward-sloping curve, where the real interest rate is located on the vertical axis and inflation rate on the horizontal axis. Shifts on the MP curve are produced by actions of the Federal Reserve.

In the case of two goods and two individuals, the contract curve can be found as follows. Here refers to the final amount of good 2 allocated to person 1, etc., and refer to the final levels of utility experienced by person 1 and person 2 respectively, refers to the level of utility that person 2 would receive from the initial allocation without trading at all, and and refer to the fixed total ...
An example of a demand curve shifting. D1 and D2 are alternative positions of the demand curve, S is the supply curve, and P and Q are price and quantity respectively. The shift from D1 to D2 means an increase in demand with consequences for the other variables
The Keynesian cross diagram is a formulation of the central ideas in Keynes' General Theory of Employment, Interest and Money. It first appeared as a central component of macroeconomic theory as it was taught by Paul Samuelson in his textbook, Economics: An Introductory Analysis.
In the diagram, the long-run Phillips curve is the vertical red line. The NAIRU theory says that when unemployment is at the rate defined by this line, inflation will be stable. However, in the short-run policymakers will face an inflation-unemployment rate trade-off marked by the "Initial Short-Run Phillips Curve" in the graph.
