Econ Test 1
Diminishing marginal utility
Each additional unit of a item purchased gives less marginal benefit than the previous unit, therefore, the only way I'll pay is if the price is lower
In a mixed economy, what to produce and how much to produce are determined by
Markets and the government
Example of inferior goods
More income means less demand for cheap ramen noodles
Example of normal goods
More income means more demand for jewelry
Population
More population means more demand, less population means less demand
Elastic
Percentage change in price causes a larger percentage change in quantity demanded
Inelastic
Percentage change in price causes a smaller percentage change in quantity demanded
Unitary elastic
Percentage change in price causes an equal percentage change in quantity demanded
Taste and preferences
-affected by advertising, trends, health considerations
Changes in the following cause the entire demand curve to shift
-tastes and preferences -related goods -income -population -expectations

Indeterminate with the available information
Resources are also known as

When there's a decrease in demand the demand curve shifts to the __________
Left
How does price not change

Law of demand
The price of an item determines the quantity demanded
Substitution effect

Income of consumers: inferior goods
When consumers income increases, demand for inferior goods/services decreases
Income of consumers: Normal goods/services
When consumers income increases, demand for normal goods/services increases
Income effect
When goods are expensive, money buys less. When goods are cheaper, money buys more
Example of complements
When the price of fishing poles increases, the quantity demand decreases. Therefore, the demand for its complement, lures, decreases (price for lures does not change)
Demand curve moves only on the ______ axis
X-axis
The quantity is always on the _______ axis
X-axis
The price is always on the _______ axis
Y-axis
the "other things equal" assumption means
all relevant factors (independent variables) except one remain *unchanged* when studying an economic effect
sweden has a comparative advantage in producing
herring only
sweden has an absolute advantage in producing
herring only
the PPF illustrates that
if all resources of an economy are being used efficiently, more of one good can be produced only if less of another good is produced
the fact that a society's PPF is curved demonstrates the law of
increasing opportunity cost
all points inside the PPF represent
inefficient production points
opportunity cost
is measured by how much of one good/service a person has to forgo in order to get some stated amount of another good/service
finland has an absolute advantage in producing
neither cell phones or herring
all points outside the PPF represent
non-feasible production points
the long-run growth rate of an economy will increase (the PPC will shift out) by an increase in all of the following EXCEPT
real interest rate
a decline in the available natural resources will cause the PPF to
shift inward
a production possibility frontier (PPF) shows
that choosing to produce one good implies sacrificing production of other goods
when ina decides to buy a $200 pair of high heels instead of a $400 dress to wear to the prom, her opportunity cost is

a PPF illustrates the - facing an economy that - only 2 goods
trade-offs; produces
