The dynamic aggregate demand curve shifts when either fiscal policy or monetary policy is changed or any other kinds of shocks to aggregate demand occur. [5]: 411 Changes in the level of potential Y also shifts the AD curve, so that this type of shocks has an effect on both the supply and the demand side of the model. [5]: 412
The original version of the model shows the price level and level of real output given the equilibrium in aggregate demand and aggregate supply. The aggregate demand curve's downward slope means that more output is demanded at lower price levels. [ 56 ]
A post-Keynesian theory of aggregate demand emphasizes the role of debt, which it considers a fundamental component of aggregate demand; [7] the contribution of change in debt to aggregate demand is referred to by some as the credit impulse. [8] Aggregate demand is spending, be it on consumption, investment, or other categories. Spending is ...
Supply theories are based on the neo-Keynesian cost-push model and attribute stagflation to large disruptions to the supply side of the supply-demand market equation, such as when there is a sudden scarcity of key commodities, natural resources, or the natural capital needed to produce goods and services.

Supply chain as connected supply and demand curves. In microeconomics, supply and demand is an economic model of price determination in a market.It postulates that, holding all else equal, the unit price for a particular good or other traded item in a perfectly competitive market, will vary until it settles at the market-clearing price, where the quantity demanded equals the quantity supplied ...
Keynesian economics developed during and after the Great Depression from the ideas presented by Keynes in his 1936 book, The General Theory of Employment, Interest and Money. [5] Keynes' approach was a stark contrast to the aggregate supply-focused classical economics that preceded his book.
In economics, aggregate supply (AS) or domestic final supply (DFS) is the total supply of goods and services that firms in a national economy plan on selling during a specific time period. It is the total amount of goods and services that firms are willing and able to sell at a given price level in an economy. [ 1 ]
A positive demand shock increases aggregate demand (AD) and a negative demand shock decreases aggregate demand. Prices of goods and services are affected in both cases. When demand for goods or services increases, its price (or price levels) increases because of a shift in the demand curve to the right. When demand decreases, its price ...
