Solution
Solution Steps
Step 1: Identify the initial equilibrium point
The initial equilibrium point is given as \( E_0 \), where the initial aggregate demand curve \( AD_0 \) intersects the initial short-run aggregate supply curve \( SRAS_0 \).
Step 2: Determine the effect of an increase in input prices
An increase in the prices of inputs widely used in production will cause the short-run aggregate supply curve to shift to the left. This is because higher input prices increase production costs, reducing the quantity of goods and services that firms are willing to supply at any given price level.
Step 3: Identify the new equilibrium point
With the leftward shift of the short-run aggregate supply curve from \( SRAS_0 \) to \( SRAS_1 \), the new equilibrium point will be where the new short-run aggregate supply curve \( SRAS_1 \) intersects the initial aggregate demand curve \( AD_0 \). This intersection occurs at point \( E_6 \).
