Supply Flashcards
What is supply?
(Whole line)
Quantity of a good/service/resource that sellers are willing and able to supply to the market at various prices over a fixed time period (all else held constant)
Why is supply important?
Determines number of goods/services that are available to consumers in the market as well as the prices that consumers will have to pay to purchase them
What is the law of supply? (Direct relationship)
As the price of a good rises, the quantity supplied will increase and vice versa, all else held constant
Increased opportunity costs, increased supply
Supply Schedule
Table representation of the relationship between the price of a good and the quanitties producers are willling and able to supply over fixed time period (all else held constant)
Supply Curve
Graphical representation of the supply schedule
Quantity Supplied
(Specifc Place/Position on the Line)
Quantity of a good that producers are willing and able to supply at a given price
Diminishing Marginal Productivity
(MB & MC)
At least one input of prodution is fixed, the marginal productivity of additonal variable resources will eventually fall, all else held constant
How does labor affect productivity?
Producers choices:
- Purchases additional resources
- Use existing resources more intensively
- Shift resources from one good to another
As more labor increases, each additional unit of productivity falls
What is market supply?
Overall total for a good - horizontal summation of the quantities suppplied by firms, states, nations at each price over a fixed time period, all else held constant
What is shift in supply?
(nonprice determinant)
Change in the quanity of a good supplied at every price
Increase supply = righward shift of the curve (increase quantity supplied)
Decrease supply = leftward shift of the curve (decrease quantity supplied)
What is movement along the supply curve?
Change in the quantity of a good supplied due to a change in its price
Why does supply matter to consumers?
Low supply = less output in market (try the good while you still can)
High supply = hold off on your purchase until the good is more widely available
What are the 5 nonprice determinants of supply?
- Subsidy
- Taxes
- Resource Costs
- Technology
- # of Sellers and their expectations
What is subsidy?
How does it affect the supply curve?
(Direct relationship)
Payment made by the government that does not necessarily require an exchange of economic activity in return
High subsidies + High supply = rightward shift of curve (increase)
Low subsidies + Low supply = leftward shift of curve (decrease)
What are taxes?
How does it affect the supply curve?
(Inverse Relationship)
Payment made by the government that is the result of economic activity (collected from individuals and firms)
High taxes + Low supply = leftward shift of curve (decrease)
Low taxes + High supply = rightward shift of curve (increase)
