Module 42: Economics, Strategy, and Globalization Flashcards
Microeconomics
focuses on the behavior and purchasing decisions of individuals and firms
Demand curve
downward shifting
inverse relationship between the price and quantity demanded
Demand curve shift
curve shifts when variables other than price change
example: if the price of a substitute product increases in price, the demand for the product
they don’t want to buy the substitute product if price has gone up, they will buy yours
examples: change in price of other goods and services, consumer taste, spendable income, wealth, and the size of the market
Demand curve movement
when the demand moves along the demand line, only price changes
price of other goods and services (demand curve shift)
direct relationship- as goods that may be purchased instead go up in price the demand for your product goes down
price of compliment products (demand curve shift)
inverse relationship- as the price of compliment goods go up, the demand for your product goes down
example: price of hamburger increases, the demand for hamburger buns decrease
expectations of price increase (demand curve shift)
direct relationship- if the price of the good is expected to increase in the future, there will be an increase in demand
consumer income and wealth (demand curve shift)
generally a direct relationship- as wealth goes up, the demand for many (normal) products goes down
certain goods are inferior to this (bread, potatoes, milk) and the demand for these goods actually goes up. this is because consumers buy more inferior goods when they are short money
consumer tastes (demand curve shift)
intermediate relationship- the effect depends on whether the shift is towards or away from the product
size of the market (demand curve shift)
direct relationship- as the size of the market increases, the demand for the product will increase
group boycott (demand curve shift)
inverse relationship- if a group of consumers boycott a product, the demand will be increased
price elasticity of demand
measures the sensitivity of demand to a change in price
% change in quantity demanded/ percent change in price
price elasticity of demand- arc method
to make results the same regardless of whether there is an increase or decrease in price
(change in quantity demanded/ average quantity)/
(change in price/ average price)
income elasticity of demand
measures the change in the quantity demanded of a product given a change in income
% change in quantity demanded/ % change in income
cross-elasticity of demand
measures the change in demand for a good when the price of a related or competing product is changed
% change in the quantity demanded of Product X/ % change in the price of Product Y
Substitution effect
refers to the fact that as the price of a good falls, consumers will use it to replace similar goods
Income effect
refers to the fact that as the price of a good falls, consumers can purchase more with a given level of income
Law of diminishing marginal utility
the more goods an individual consumes, the more total utility (satisfaction) an individual receives
halloween candy (the first piece tastes great but as you keep going you start to turn green)
indifference curves
illustration (in a graph) the combination of two items that provide equal utility
page 137
budget constraint
the optimal level of consumption of two items that provide equal utility
the graph will show that the line intersects the highest possible utility curve
personal disposable income
amount of income consumers have after receiving transfer payments from the government (welfare payments) and paying their taxes
when personal disposable income goes up, consumers buy more. They buy less when it goes down
consumption function
the relationship between changes in personal disposable income and consumption
consumption for a period= the constant + (the slope of the consumption function x disposable income for the period)
marginal propensity to consume (MPC)
the constant in the consumption function measures the marginal propensity to consume
it describes how much of each additional dollar in personal disposable income that the consumer will spend
marginal propensity to save (MPS)
the percentage of additional income that is saved
MPC+MPS=1
it has to equal one
