The calculation for the output gap is (Y–Y*)/Y* where Y is actual output and Y* is potential output. If this calculation yields a positive number it is called an inflationary gap and indicates the growth of aggregate demand is outpacing the growth of aggregate supply—possibly creating inflation; if the calculation yields a negative number it is called a recessionary gap—possibly ...
The AD–AS or aggregate demand–aggregate supply model (also known as the aggregate supply–aggregate demand or AS–AD model) is a widely used macroeconomic model that explains short-run and long-run economic changes through the relationship of aggregate demand (AD) and aggregate supply (AS) in a diagram.
The introduction of inflationary expectations into the equation implies that actual inflation can feed back into inflationary expectations and thus cause further inflation. The late economist James Tobin dubbed the last term "inflationary inertia", because in the current period, inflation exists which represents an inflationary impulse left ...

An economic model is a theoretical construct representing economic processes by a set of variables and a set of logical and/or quantitative relationships between them. The economic model is a simplified, often mathematical, framework designed to illustrate complex processes.
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 .
A traditional AD–AS diagram showing a shift in AD, and the AS curve becoming inelastic beyond potential output The AD–AS model is a common textbook model for explaining the macroeconomy. [ 53 ] The original version of the model shows the price level and level of real output given the equilibrium in aggregate demand and aggregate supply .
