Because using aggregate demand and aggregate supply is a good way to see the big picture of the economy, which is most of the point of macroeconomics, and because they can be related to each other in meaningful, logical ways.
Short-run fluctuations in the economy
In economics, the supply curve in the aggregate supply and demand model shifts drastically to the left due to an inadequacy of resources or because the demand overpowers the supply.
AD-AS represents aggregate demand curve (AD) and aggregate supply curve (AS). "In the aggregate demand-aggregate supply model, each point on the aggregate demand curve is an outcome of the IS-LM model for aggregate demand Y based on a particular price level. Starting from one point on the aggregate demand curve, at a particular price level and a quantity of aggregate demand implied by the IS-LM model for that price level, if one considers a higher potential price level, in the IS-LM model the real money supply M/P will be lower and hence the LM curve will be shifted higher, leading to lower aggregate demand; hence at the higher price level the level of aggregate demand is lower, so the aggregate demand curve is negatively sloped
To construct the aggregate demand and aggregate supply (AD-AS) model, one plots aggregate demand (AD) and aggregate supply (AS) curves on a graph with the price level on the vertical axis and real GDP on the horizontal axis. The intersection of these curves indicates the equilibrium price level and output. This model can illustrate macroeconomic problems, such as inflation or recession, by showing shifts in AD or AS. Policymakers can use the model to evaluate the potential effects of monetary policy (like interest rate changes) and fiscal policy (like government spending) on the economy's overall output and price level.
It is a diagrammatic representation of a model of aggregate demand determination based upon the locus ofequilibrium points in the aggregate expenditure sector (IS) and the monetary sector(LM).

The quantity of full employment in the aggregate supply aggregate demand model is similar to the conditions in which other model. (Market Supply and Demand.)

supply and demand model predicts that a price floor will result in
supply and demand
Using the AD-AS model, start with a long-run equilibrium and assume velocity V is constant, then analyze the following case: The pandemic recession is the result of adverse Demand and Supply shocks. a. What happens to the Aggregate Demand curve and What happens to the Aggregate Supply curve? b. What happens to output Y and the price level P in the short run? c. What short-run problems are created for the labor and goods markets? d. What kinds of stabilization policies are required to stimulate recovery? Describe the 5 specific tools and their directions of change to be used.
Macroeconomics deals with studying the behavior, decision making, performance and structure of an economy as a whole instead of its component parts. Macroeconomics usually studies the aggregate supply/aggregate demand model, using it to explain the performance of the GDP of a nation based on the various components.
