There is an inverse relationship between aggregate demand and the price level, known as the aggregate demand curve. As the price level increases, aggregate demand decreases, and vice versa.

Aggregate demand is the total demand for goods and services in an economy, and it is composed of consumption, investment, government spending, and net exports.

There is a positive relationship between aggregate supply and the price level, known as the aggregate supply curve. As the price level increases, aggregate supply also increases, and vice versa.

Aggregate supply is the total supply of goods and services in an economy, and it is composed of labor, capital, technology, and natural resources.

The equilibrium price level is the price level at which the quantity of goods and services demanded is equal to the quantity of goods and services supplied.

An increase in aggregate demand shifts the aggregate demand curve to the right, leading to a higher equilibrium price level.

An increase in aggregate supply shifts the aggregate supply curve to the right, leading to a lower equilibrium price level.

A decrease in aggregate demand shifts the aggregate demand curve to the left, leading to a lower equilibrium quantity of output.

An increase in aggregate supply shifts the aggregate supply curve to the right, leading to a higher equilibrium quantity of output.

Monetary policy can be used to influence aggregate demand by changing interest rates and the money supply.

Fiscal policy can be used to influence aggregate demand by changing government spending and taxes.

An increase in aggregate demand can lead to higher inflation, and vice versa.

An increase in aggregate demand can lead to lower unemployment, and vice versa.

In the long run, the aggregate supply curve is vertical at the full-employment level of output, indicating that the economy cannot produce more output without causing inflation.

In the short run, the aggregate supply curve is positively sloped, indicating that the economy can produce more output at higher prices.
