A market with few government restrictions on how a good can be produced or sold or on how factors of production can be employed.
|
|
Product Markets
|
markets for goods
|
|
Production Possibilities Frontier
|
A curve showing the maximum attainable combinations of two products that may be produced with available resources and current technology.
A point outside of the PPF is unattainable A point under the PPF is inefficient in using its resources A point ON the PPF is efficient
|
|
Trade
|
The act of buying are selling.
|
|
Increasing Marginal opportunity Cost
|
The more resources already devoted to any activity, the smaller the payoff to devoting additional resources to that activity.
As the economy moves DOWN the PPF, it experiences INCREASING marginal opportunity costs. Some workers, machines, and other resources are better suited to one use …
|
|
Competitive market equilibrium
|
A market equilibrium with many buyers and many sellers.
|
|
Complements
|
goods that are used together
A decrease in the price of a complement causes the demand curve for the other good to shift to the right.
|
|
Demand Curve
|
A curve that shows the relationship between the price and the quantity of the produced demanded.
|
|
Income Effect
|
The change in the QD of a good that results from the effect of a change in the goods' price on consumers' purchasing power.
PURCHASING POWER: the amount of goods a consumer can buy on a fixed income. When price falls, purchasing power goes up--> consumers buy larger quantities of that go…
|
|
Inferior good
|
a good for which the demand increases as income falls and decrease as income rises.
Example: if income rises, you buy less ramen noodles.
|
|
Law of Demand
|
The rule that when the price of a product falls, the QD of the product will increase, and visa versa.
|
|
Law of Supply
|
The rule that increases in price cause increases in the QS, and decreases in price cause decreases in the QS.
|
|
Market demand
|
The demand by all the consumers of a given good.
|
|
Market equilibrium
|
A situation in which QD = QS
|
|
Normal Good
|
a good for which the demand increases as income rises and decreases as income falls.
Example: if income rises, you buy less spam and more steak

Quantity Demanded
|
The amount of a good that a consumer is WILLING and ABLE to purchase at a given price.

The amount of a good that a firm is willing and able to supply at a given price
|
|
Shortage
|
QD > QS
|
|
Substitutes
|
Goods that can be used for the same purpose.
A decrease in the price of a substitute causes the demand for another good to shift left. An increase in the price of a substitute causes the demand of another good to shift right.
|
|
Substitution Effect
|
The change in the QD of a good that results from a change in PRICE, making the good more or less expensive relative to the other goods that are substitutes.
|
|
Supply Curve
|
a curve that shows the relationship between the price and the QS of a product.
|
|
Surplus
|
QS > QD
|

|
A positive or negative change in the ability of a firm to produce a given level of output with a given quantity of inputs.
|
|
Variables that SHIFT Market Demand
|
income
prices of related goods tastes population and demographics expected future prices
|
|
Change in Quantity versus Change in Quantity Demanded
|
∆ in demand: a shift of the demand curve
occurs if there is a change in one of the variables, OTHER THAN PRICE, that affects the willingness of consumers. ∆ in QD: movement along the demand curve occurs b/c of a change in the product's PRICE.
|
|
Variables that SHIFT Supply
|
Prices of inputs
technological change prices of substitutes in production number of firms in the market expected future prices
|
|
Consumer Surplus
|
the difference between the highest price a consumer is willing to pay and the price the consumer actually pays

Occurs when a tax is imposes, ceilings or floors
|
|
Economic efficiency
|
A market outcome in which the marginal benefit to consumers of the last unit produced is equal to its marginal cost of production. When the sum of CS and PS is at its maximum
MB = MC
|
|
Economic surplus
|
The sum of consumer surplus and producer surplus
|
|
Marginal benefit
|
The additional benefit to a consumer from consuming one more unit of a good.

The additional cost to a firm of producing one more unit of a good
|
