macro test 3
How is inflation rate calculated?
Inflation rate = (price level this year - price level last year) / price level last year x100
how do you convert a nominal variable to a real variable
apply the inflation adjustment formula
Outlet substitution bias
as the structure of retailing changes, people switch to buying from cheaper sources, but the CPI, as measured, does not take account of this outlet substitution Ex. switching from Publix to Walmart
what is a major challenge with CPI?
can overstate true inflation
What is fiat money?
inconvertible paper money made legal tender by a government decree.
what type of market is the labor market
input market
what is indexation
is automatically adjusting wages, benefits, tax brackets, and the like to compensate for inflation
Quality change bias
quality improvements occur every year part of the rise in the price is payment for improved quality and is not inflation. CPI counts all price rises as inflation
what is the interest rate in terms of changes in your purchasing power
real interest rate
what is nominal wage rigidity
reluctance to cut nominal wages
what do efficiency wages cause
Structural unemployment
Unemployment rate formula
Unemployed / labor force x 100
what is cyclical unemployment?
Unemployment that is due to a temporary downturn in the economy
an estimate made in 1996 says what about CPI
says that the CPI overstates inflation by 1.1% points each year
what is the labor force participation rate
share of the working age population that is either employed or unemployed
two costs of expected inflation
shoe-leather cost menu cost
what is underemployment
someone who has some work but wants more hours or whose job isn't adequate using their skills
what is marginally attached
someone who wants a job, and who has looked for a job within the past year, but who isn't counted as unemployed because they aren't currently searching for a job.
what is involuntarily part-time?
someone who wants full time work but is working part-time because they haven't found a full time job.
what is equilibrium in the labor market
where the supply of labor equals the demand fro labor
Labor Force
working age population that either has a job or would like a job
Long term unemployment is associated with...
worse life expectancy, morbidity, clinical depression
what two things did people use before fiat money?
- barter - commodity money
3 issues brought by money illusion
- distorted prices - mispricing - nominal wage rigidity
what causes frictional unemployment?
- job search resources - skills/geographical mismatch - unemployment insurance
what are the two ways to measure changes in business prices?
- producer price index - GDP deflator
inflation adjustment formula
Today's Dollars = Another times dollars X Price level today/ Price level over time
when should you focus on real monetary variable? (3)
- to analyze when you are becoming better paid - to assess whether your stocks have become more valuable - to evaluate whether your sales staff are performing better
what causes structural unemployment?
- when wages are unable to fall to the market clearing wage - job protection regulation makes it hard to find workers - minimum wage laws
CPI construction steps
1) find out what people typically buy 2) collect prices from the stores where people do their shopping 3) tally up the price of the basket of goods and services 4) calculate the inflation rate
what are the three causes of unemployment?
1) frictional unemployment 2) structural unemployment 3) cyclical unemployment
3 reasons for inflation
1) general increase in demand, aggregate demand, as opposed to individual good demand 2) an increase in the price of widely used inputs 3) an increase in money supply
four challenges brought by CPI
1) new goods bias 2) quality change bias 3) commodity substitution bias 4) outlet substitution bias
six ways to protect yourself from unemployment
1)Don't postpone job search 2)Build up a nest egg 3)Build new skills 4)Look for new opportunities while you remain unemployed 5)Use your network 6)Avoid long-term unemployment
what are the three alternative measures of unemployment?
1)Underemployment 2)marginally attached 3)involuntarily part-time
labor force =
= employed + unemployed
what is CPI in the base year?
100
real interest rate =
= nominal interest rate - inflation rate
which measure of inflation do we use for estimating the price of all output/real GDP
GDP deflator
labor force participation rate formula
Labor force / working age population x 100
What is barter?
Trading/exchanging of goods and services without the use of money
Equilibrium unemployment rate
The long-run unemployment rate to which the economy tends to return
who is counted in labor market statistics?
Those age 16 or older who are not in the military or institutionalized are considered the working age population.
what can inflation result in
a decline in the purchasing power of money
GDP deflator
a price index that tracks the price of all goods and services produced domestically -(nominal GDP / real GDP) x 100
producer price index (PPI)
a price index that tracks the price of inputs into the production process
nominal variable
a variable measured in dollars (whose value may fluctuate over time)
real variable
a variable that has been adjusted to account for inflation
What are efficiency wages?
above-equilibrium wages paid by firms to increase worker productivity
what does personal consumption expenditure adjust for and why is this possible
adjusts for substitution bias, can do this because it is not based on a fixed basket of goods
hyperinflation
an extremely high rate of inflation Makes most aspects of life harder and erodes all the functions of money
consumer price index (CPI)
an index that tracks the average price consumers pay over time for a representative "basket" of goods and services
which measure of inflation do we use for cost of living
consumer price index (CPI)
Which inflation measure is used by forecasters?
core inflation - core CPI or core PCE
which measure of inflation do we use for forecasting underlying inflation trends
core inflation (excludes food and energy)
what principle does the new goods bias contradict
cost benefit principle
what type of money is money in the U.S.
fiat money
what type of price increase is inflation
general price increase
what does a high unemployment rate mean for the government
means they receive lower taxes but spend more
consumer price index (CPI)
measure of inflation most relevant to our lives as a consumer. Tracks the average price consumers pay overtime for a representative "basket" of goods and services
What is commodity money?
money that has intrinsic value in addition to being money - gold coins
what is the natural unemployment rate
natural unemployment rate = frictional unemployment + structural unemployment
new goods bias
new goods that were not available in the base year appear, and, is they are more expensive than the goods they replace they put an upward bias into the CPI
what issue does money illusion create
nominal wage rigidity
working age population
noninstitutionalized civilians over 16 years old
what is hysteresis
occurs when a period of high unemployment leads to a high equilibrium unemployment rate
Shoe-leather cost
on the consumer side, the resources wasted when inflation encourages people to reduce their money holdings. the cost of time and effort that people spend trying to counteract the effects of inflation.
menu cost
on the producer side, the cost of changing prices
Which inflation measure is used for monetary policy?

producer price index
children whose parents experience unemployment tend to...
suffer worse academically, mentally, and future economic outcomes
money illusion
the (mistaken) tendency to focus on nominal dollar amounts instead of inflation-adjusted amounts
Commodity substitution bias
the market basket of goods used in calculating the CPI is fixed and does not take into account consumers' substitutions away from goods whose relative prices increase
what is frictional unemployment?
unemployment due to the time it takes for employers to search for workers and for workers to search for jobs
what is structural unemployment?
unemployment that occurs because wages don't fall to bring labor demand and supply into equilibrium
