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
non-income factors that affect consumption
- expectations about future prices of goods
- quantity of consumer liquid assets
- amount of consumer debt
- stock of consumer durable goods
- attitudes about saving money
- interest rates
Supply
shows the amount of a product that would be supplied at various prices
graphically a supply curve shows a direct relationship between price and quantity sold
the higher the price, the more products that would be supplied
a change in market price of the product results in a movement along the existing supply curve
supply curve shift
occurs when supply variables other than price change
example: if the cost to procude the product increase, the supply curve would shift upward and to the left
variables that cause the supply curve to shift
changes in the number or size of producers, changes in various production costs (wages, rents, raw materials), technological advances, and government actions
change in the number of producers (supply shift)
direct relationship- generally an increase in the number of producers will cause an increase in the amount of goods supplied at a given price
change in production costs or technological advances (supply shift)
inverse relationship- as production costs go up fewer products will be supplied at a given price.
if costs go down, more products will be produced
government subsidies (supply shift)
direct relationship- in effect reduce the production cost of goods and, therefore, increase the goods supplied at a given price
government price controls (supply shift)
inverse relationship- price controls would tend to limit the amount of goods supplied by holding the price artificially low
price of other goods (supply shift)
inverse relationship- if other products can be produced with greater returns, producers will produce those goods instead
price expectations (supply shift)
direct relationship- if it is expected that prices will be higher for the good in the future, production of the good will increase
elasticity of supply
measures the percentage change in the quantity supplied of a product resulting from a change in the product price
elasticity of supply formula
% change in quantity supplied/ % change in price
market equilibrium
a products equilibrium price is determined by demand and supply
it is the price at which all the good offered for sale will be sold (quantity demanded=quantity supplied)
the equalibrium price is the price at which the demand and supply curve intersect
governing intervention
government actions that may change market equilibrium through taxes, subsidies, and rationing
example: subsidy paid to farmers will reduce the cost of producing a particular farm product and therefore cause the equilibrium price to be lower than it would be without the subsidy
import taxes on the other hand would increase the cost of an imported item and cause the equilibrium to be higher
price ceiling
a specified maximum price that may be charged for a good
if the price ceiling is set for a good below the price equilibrium it will cause shortages because suppliers will devote their production facilities to produce other goods
price floor
a price floor is a minimum specified price that may be charged for a good
if the floor is set for a good above the equilibrium price, it will cause overproduction and surpluses will develop (farmers will get more than what it actually cost them to make it and it is more than what they would normally sell it for)
externalities
another factor that cause inefficiencies in the pricing of goods in the market
the term is used to describe damage to common areas that is caused by the production of certain goods
example: pollution
because externalities are not included in the production cost, supply is higher and the price is lower than is appropriate
govt laws and regs attempt to force firms to change their production methods to make externalities part of the cost of production (this causes the market price to be a more accurate reflection of the cost to society)
average fixed cost (AFC)
fixed cost per unit of production
goes down as more units are produced
average variable cost
total variable costs divided by the number of units produced
initially stays constant until the inefficiencies of producing in a fixed-sized facility cause variable costs to begin to rise
marginal cost
the added cost of producing one extra unit
it initially decreases but then begins to increase due to inefficiencies
average total cost
total costs divided by the number of units produced
its behavior depends on the makeup of fixed and variable costs
law of diminishing returns
as we try to produce more and more output with a fixed productive capacity, marginal productivity will decline
macroeconomics
looks at the economy as a whole
it focuses on measures of economic output, employment, inflation, and trade surpluses or deficits
three major sectors of the economy
consumers
business
government
nominal gross domestic product (GDP)
price of all goods and services produced by a domestic economy
real GDP
the price of all goods and services produced by the economy at price level adjusted (constant) prices
adjust for inflation
Potential GDP
maximum amount of production that could take place in an economy without putting pressure on the general level of prices
without inflation
GDP gap
the difference between potential GDP and real GDP
net domestic product (NDP)
GDP minus depreciation
gross national product (GNP)
the price of all goods and services produced by labor and property supplied by the nation’s residence
business cycles
a fluctuation in aggregate economic output that lasts for several years
peaks and troughs
Okums Law
high output growth is generally associated with a decrease in the unemployment rate
makes perfect sense because when output increases less, then everyone is busy working to contribute to GDP
recession
a period of negative GDP growth
depression
a deep long lasting recession
cyclical business sector
perform better in periods of expansion and worse in periods of recession
defensive business sector
affected little by business cycles and some may actually perform better in periods of recession
if you sell an inferior good, people buy in recession
leading indicators
this is what is going to happen
average weekly hours
manugacturers new orders
stock prices
interest rate spread, 10 year treasury bonds
coincident indicators
this is whats happening right now
number of employees on payroll
personal income minus transfer payments
industrial production
lagging indicators
this is what has already happened
average duration of unemployment inventories to sales ratio average prime rate (rate you give to your best customers) commercial and industrial loans chronic unemployment
investment
expenditures for residential construction, inventories and plant and equipment
the most important determinant of business investment is expectations about profitability
factors that affect investment spending
most volatile portion of GDP
the rate of technology growth
the real interest rate (nominal rate - the inflation premium)
the stock capital of goods
actions by the government
the acquisition and operating cost of capital goods (if there’s not deflation- people don’t buy today because they think the price will be cheaper tomorrow)
autonomous investment
includes expenditures made by businesses based on expected profitability that are independent of the level of national income
they are constant regardless of whether the economy is expanding or contracting
induced investment
is incremental spending based on an increased level of economic activity
accelerator theory
as economic activity increases, capital investments must be made to meet the level of increased demand
the increased capital investment in turn creates additional economic demand which further feeds the economic expansion
unemployment
the unemployment rate is the percent of the total labor force that is unemployed at a given time
unemployed because of cyclical, frictional, or structural causes
frictional unemployment
occurs because individuals are forced or voluntarily change jobs
also new entrants into the work force fall into this category (recent graduates)
structural unemployment
occurs due to changes in demand for products or services, or technological advances causing not as many individuals with a particular skill to be needed
reduced by retraining programs
cyclical unemployment
caused by the condition in which real GDP is less than potential GDP
therefore, such unemployment increases during recessions and decreases during expansions
Inflation
rate of increase in the price level of goods and services, usually measured on an annual basis
generally causes economic activity to contract and redistributes income and wealth
Deflation
a term used to describe a decrease in the price levels
havent had since 1930s
very damaging because businesses dont want to bottow money that has more purchasing , and they dont want to invest in plant and equipment given that the cost of plant and equipment is declining
price index measures
the prices of a basket of goods and/or services at a point in time in relation to the prices in a base period
consumer price index
producer price index
GDP deflator
consumer price index
measures the price that urban consumers paid for a fixed basket of goods and services in relation to the price of the same goods and services purchased in some base period
producer price index
measures the prices of finished goods and materials at the wholesale level
price index for 2013 with the reference period as 2008 formula is:
(price of 2013 market basket in 2013/ price of 2013 market basket in 2008) x 100
GDP deflator
measures the prices for net exports, investment, government expenditures, and consumer spending
is the most comprehensive measure of price level (price index)
causes of inflation
demand-pull
cost-push
demand-pull
inflation occurs when aggregate spending exceeds the economy’s normal full-employment output capacity
real GDP exceeds potential GDP
usually happens a the peak of a business cycle
cost-push
inflation occurs from an increase in the cost of producing goods and services
decreases aggregate output and unemployment because consumers are not willing to pay the inflated prices
relationship between inflation and unemployment
is inverse
when unemployment rate is low, inflation tends to increase
inflation tends to decrease when the unemployment rate is high
the relationship is depicted by the Philips Curve
personal disposable income
the amount of income that individuals receive and have available to purchase goods and services
personal income minus personal taxes
