Trang 2LOS LOS Describe the business cycle and its phases
Business cycle is fluctuation of GDP over time
• Alternating periods of expansion and recession
Expansions: Increases in economic output
Recessions: Decrease in industrial production, personal income, employment, and sales
• Cycles generally last from 1 to 12 years
Varies greatly over time
Trang 3LOS LOS Describe the business cycle and its phases
Business Cycle Phases
1 Expansion
a) Growth of econ activity
b) Rising wages, prices, and
employment levels
2 Peak
a) Growth rate peaks
b) Economy reaches productive
capacity
3 Contraction
a) Economic activity slows
b) Employment drops, overall
production declines
4 Trough
a) Negative trend levels off
Trang 4LOS LOS Describe how resource use, housing sector activity, and
external trade sector activity vary as an economy moves through the business cycle
1 Expansion
• Low rates encourage business investment and allow financing for large purchases like housing
• Employment picks up as production increases
• Wage and employment growth increase consumer spending
2 Peak
• Economic growth rate flattens out
• The economy is at maximum employment
• Inflation concerns cause the consumption rate to slow
Trang 5LOS LOS Describe how resource use, housing sector activity, and
external trade sector activity vary as an economy moves through the business cycle
3 Contraction
• Purchasing starts to slow
• Inventories build quickly as demand falls, so companies cut back
on hours and lay off workers
• Increasing unemployment further decreases consumer demand
4 Trough
• Lowest level of economic growth/contraction
• High unemployment and low levels of business spending
• Expansionary monetary policy encourages new investment
Trang 6LOS LOS Describe theories of the business cycle
Several conflicting theories of how business cycles work and how government intervention affects them:
1 Models with Money
• Believe inflation is the result of the business cycle
• Monetary policy necessary to counteract the impacts of inflation on spending
2 New Classical School
• Economic growth is based on the rational expectations of economic agents
• Government interventions are not effective
Trang 7LOS LOS Describe theories of the business cycle
3 Neoclassical and Austrian Schools
• Free markets will reach equilibrium without the need for government interference
• Forces of supply and demand will moderate large swings in the
business cycle
4 Keynesian and Monetarist School
• Market forces are not enough to combat large economic swings
• Spending is necessary to keep economy growing, so government spending during recession is needed to offset loss of private sector spending
Trang 8LOS LOS Describe types of unemployment and compare measures of
unemployment
Unemployment is when willing and capable workers are unable to find
jobs
Three Primary types of unemployment:
1 Structural
• No longer demand for a specific type of worker (Telegram Operator)
2 Frictional
• Workers changing jobs or transitioning from one to another
• Mismatches based on location or skills
3 Cyclical
• Based on business cycles
Trang 9LOS LOS Describe types of unemployment and compare measures of
unemployment
How can we measure unemployment?
• Unemployment rate:
Percentage of people in labor force that want a job but can’t find one
• Payroll Employment:
Monitors changes in total payroll growth/shrinking over time
Trang 10LOS LOS Explain inflation, hyperinflation, disinflation, and deflation
1 Inflation
• Persistent increase in price level of goods and services over time
• Caused by:
i Increasing money supply during slow economic growth
ii Injecting large amounts of money in the economy
• Advantages of inflation:
i Reduction in amount of debt
ii Increasing unemployment (due to nominal wage “stickiness“)
• Disadvantages of inflation
i Increases opportunity cost of holding money
ii Discourages savings and investments
Trang 11LOS LOS Explain inflation, hyperinflation, disinflation, and deflation
2 Hyperinflation
• Extreme case of inflation (above 100%)
• Causes:
i Imbalance between supply and demand of money
ii Excess printing of currency
iii.Lost confidence in country’s currency
• Effects:
i The public transfers wealth to the government
Trang 12LOS LOS Explain inflation, hyperinflation, disinflation, and deflation
3 Deflation
• Decrease in price level when money supply is reduced
• Causes:
i Reduced money supply
ii Increased econ productivity grows supply of goods
• Effects:
i Discourages expenditures and investing
ii Decreases aggregate demand
4 Disinflation
• Reduction in the inflation rate
Deflation would be an inflation rate of -2%, while disinflation would
be a change in the inflation rate from 9% one year to 8% in the next
Trang 13LOS LOS Explain the construction of indices used to measure
inflation
A price index is used to track price level changes over time
• Most indexes use the Laspeyres method
Three steps to creating a price index:
1 Identify kind of index: yearly, monthly, or weekly
2 Identify basket of goods and services to include
3 Calculate general price level of the previous and current periods
4 The price index for the base year is set to be 100 Calculate the price index for the current year
5 The inflation rate is the price index for the current year divided by the price index for the base year minus 1
Example >>
Trang 14LOS LOS Explain the construction of indices used to measure
inflation
Here is part of a price index for American households What is the inflation rate for 2018?
Trang 15LOS LOS Explain the construction of indices used to measure
inflation
Here is part of a price index for American households What is the
inflation rate for 2018?
3 To get the general price level, multiply all terms of each year
together
4 The price index for the base year is set at 100 To get the price level
for 2018, divide the price level of 2017 by the price level of 2018
5 The inflation rate is then simply the price index of 2018 divided by
the price index of 2017 minus one
Trang 16LOS LOS Compare inflation measures, including their uses and
limitations
1 Consumer Price Index
• Looks at basket of goods and tracks their purchase prices over time
• Uses a fixed basket of goods and services, such as the Laspeyres index
• Several limitations:
i Bias against new products
ii Bias against increasing quality of goods over time
iii Bias against substitution effect for goods not in basket
The Fisher Index was created to correct substitution bias of
Laspeyres
2 Producer Price Index
• Includes products at all stages of production process
Trang 17LOS LOS Distinguish between cost-push and demand-pull inflation
1 Cost-Push Inflation
• Caused when price increases increase costs of production and
reduce aggregate supply
• Increases production costs flow through to higher costs of goods
and services
• Increased prices could be from increasing wages or higher prices for inputs like raw materials
2 Demand-Pull Inflation
• Increase in aggregate demand outpaces ability to increase supply
• “Too much money chasing too few goods.”
• Supply shortfall leads to price increases
Trang 18LOS LOS Interpret a set of economic indicators and describe their
uses and limitations
Economic indicators give information about the condition of the
economy and are used for determining the current state and trends of the economic cycle
1 Leading Indicators
• Intended to predict future movements of the economy
• Include share prices, consumer durables, and net business
formations
2 Lagging Indicators
• Only change when the economy has started following a certain pattern
• Includes unemployment, interest rates, GNP, and CPI
3 Coincident Indicators
• Exist during specific economic activities
• Includes GDP, retail sales, and employment levels
Trang 19LOS LOS Interpret a set of economic indicators and describe their
uses and limitations
What are the uses of Economic Indicators?
• They have unique schedule for release so investors can prepare for them
• They indicate the direction of the economy
• Analysts use them to predict possible future investments
Limitations of Economic Indicators
• The interpretation can be tricky
• Data are usually inaccurate/estimated
• Measuring GDP is practically impossible
