Supply curve
(noun)
A graph that illustrates the relationship between the price of a good and the quantity supplied.
Examples of Supply curve in the following topics:
-
Market Supply
- Market supply is the summation of the individual supply curves within a specific market where the market is characterized as being perfectly competitive.
- As a result, the supply curve is upward sloping .
- Market supply is the summation of the individual supply curves within a specific market.
- The market supply curve is simply the sum of every seller's individual supply curve.
- The market supply curve is an upward sloping curve depicting the positive relationship between price and quantity supplied.
-
Supply Schedules and Supply Curves
- A supply schedule is a tabular depiction of the relationship between price and quantity supplied, represented graphically as a supply curve.
- The supply curve is a graphical depiction of the supply schedule that illustrates that relationship between the price of a good and the quantity supplied .
- The supply curves of individual suppliers can be summed to determine aggregate supply.
- The supply curve is a graphical depiction of the price to quantity pairings presented in a supply schedule.
- Explain the price to quantity relationship exhibited in the supply curve
-
Changes in Supply and Shifts in the Supply Curve
- The supply curve depicts the supplier's positive relationship between price and quantity.
- The change in price will result in a movement along the supply curve, called a change in quantity supplied, but not a shift in the supply curve.
- Holding all else the same, the supply curve would shift inward (to the left), reflecting the increased cost of production.
- The supply curve will shift in relation to technological improvements and expectations of market behavior in very much the same way described for production costs.
- Distinguish between shifts in the supply curve and movement along the supply curve
-
Long Run Supply Decisions
- The long-run supply curve of a market is the sum of a series of short-run supply curves in the market ().
- Prior to determining how the long-run supply curve looks, its important to understand short-run supply curves.
- When this occurs, the supply curve slopes upward.
- A market's long-run supply curve is the sum of the market's short-run supply curves taken at different points of time.
- A long-run supply curve connects the points of constant returns to scales of a markets' short-run supply curves. ; the bottom of each short-term supply curve's "u."
-
The Slope of the Long-Run Aggregate Supply Curve
- The long-run aggregate supply curve is perfectly vertical; changes in aggregate demand only cause a temporary change in total output.
- The long-run aggregate supply curve is static because it shifts the slowest of the three ranges of the aggregate supply curve.
- The long-run aggregate supply curve can be shifted, when the factors of production change in quantity.
- This graph shows the aggregate supply curve.
- Assess factors that influence the shape and movement of the long run aggregate supply curve
-
Determinants of Supply
- Supply levels are determined by price, which increases or decreases supply along the price curve, and non-price factors, which shifts the entire curve.
- Number of suppliers: As more firms enter the industry the market supply curve will shift out driving down prices.
- The market supply curve is the horizontal summation of the individual supply curves.
- For example, a technological improvement that reduces the input cost of a product will shift the supply curve outward, allowing suppliers to provide a greater supply at the same price level.
- If the price of a good changes, there will be movement along the supply curve.
-
The Slope of the Short-Run Aggregate Supply Curve
- In the short-run, the aggregate supply curve is upward sloping.
- It is possible for the short-run supply curve to shift outward as a result of an increase in output and real GDP at a given price .
- As a result, the short-run aggregate supply curve shows the correlation between the price level and output.
- This graph shows the aggregate supply curve.
- In the short-run the aggregate supply curve is upward sloping.
-
Impact of Changing Price on Producer Surplus
- Producer surplus is affected by changes in price, the demand and supply curve, and the price elasticity of supply.
- Decreases in the supply curve will cause decreases in producer surplus.
- Increases in the supply curve will cause increases in producer surplus.
- At an initial supply represented by the "Supply (1)" curve, producer surplus is the blue triangle made of $P_1$, $A$, and $C$.
- The producer surplus is directly above the supply curve and is shaded in blue.
-
Introducing Aggregate Supply
- In the short-run, the aggregate supply is graphed as an upward sloping curve.
- The short-run aggregate supply curve is upward sloping because the quantity supplied increases when the price rises.
- As a result, there is a positive correlation between the price level and output, which is shown on the short-run aggregate supply curve.
- In the long-run, the aggregate supply is graphed vertically on the supply curve.
- The long-run aggregate supply curve is static because it is the slowest aggregate supply curve.
-
Shifting the Phillips Curve with a Supply Shock
- Aggregate supply shocks, such as increases in the costs of resources, can cause the Phillips curve to shift.
- Stagflation caused by a aggregate supply shock.
- The increased oil prices represented greatly increased resource prices for other goods, which decreased aggregate supply and shifted the curve to the left .
- In this example of a negative supply shock, aggregate supply decreases and shifts to the left.
- Give examples of aggregate supply shock that shift the Phillips curve
