CFA Book 2 Economics _ Allen Study 5 Flashcards
The estimation of GDP includes:
* goods an services purchased by final users for the current period.
Personal Consumption Expenditures
household spending on consumer durable and non-durable goods and servies during the period.
Gross Private Domestic Investment
* the flow of pricate sector expenditures on durable assets plus the addition to inventories during a period. * Net Investment reduces gross nivestmen for depreciation and obsolencence of machinery / physical goods during the year.
Net Private Domestic Investment
is the Gross Private Domestic Investment less an allowance for depreciation and obolescece of machinery and other physical assets during the year.
Private Domestic Inventory Investment
the change in the stock of goods and raw materials held during a period. Inventories need not be sold in order to contribute to GDP in teh current period.
Must inventories be sold in order to contribute to the GDP in the Current Period?
No, inventories need not be sold to contribute to GDP in the current period.
Government Consumption and investment
* includes government purchases * excludes transfer payments (i.e. Social Security) * e.g money spent on law enforcement, vertern’s hospitals, highways etc.
Government Expenditures
government expenditures include transfer payments (which are not considered for GDP)
Net Exports of Goods and Services
* exports minus imports * Exports are domestically produced goods sold to friegners. * Imports are foreign-made goods purhcased by domestic consumers, investors and governments.
Which of the following are included in the calculation of GDP? 1) HH consumption of durable goods, 2) HH consumption of non durable goods, 3) HH consumption of services, 4) fixed investment, 5) Inventory Additions, 6) Depreciation, 7) Gov consumption, 8) Gov Investment, 9) Gov Expenditures, 10) Imports, 11) Exports
= 1) HH consumption of durable goods + 2) HH consumption of non durable goods + 3) HH consumption of services + 4) fixed investment + 5) Inventory Additions + 7) Gov consumption + 8) Gov Investment + 11) Exports - 10) Imports ( #6 depreciation and #9 gov expend are not incl.)
Expenditure Approach
= Personal consumption expenditures + Gross Private Domestic Investment + Gov Consumption and Investment + Net Exports
GDP Income Approach
sum of the following: 1) wages (employee compensation) 2) self-employed labor earning 3) machines, buildings, land & physical assets 4) rents, corporate profits and interest payments 5) indirect business taxes (taxes on sale of goods) 6) depreciation 7) GNP - GDP adjustment (subtract net income earned abroad)
Sum of value Added vs. Value of Final Output
* two methods for calculating GDP based on expenditures * should be equal * final output relies on final sale price of a good * Sum of value Added adds up the values added at each state of production
Sum of Value Added
* a method for calculating GDP using based on expenditures * relies on adding up the values added at each stage of production * should equal the final sale price
Value of Final Output
* a method for calculating GDP using based on expenditures * relies on the observable final sale price of a good * should equal the Sum-of-value
Nominal GDP
* measures the value of goods and services at the current prevailing prices
Real GDP
measures the total expenditures on goods and services if prices were unchanged over the year
formula Nominal GDP vs. Real GDP
Nominal GDP t = P t x Q t Real GDP t = P b x Q t where: Q t = quantitiy produced in year t (current year) P t = price in current year (year t) P b = price in base year
GDP Deflator
* expenditure data is collected in current year prices * this is used to convert expenditure data into constant prices * price index
formula GDP Deflator
= \frac{\text{value of current output at P} _{t}}{\text{value of current output at P} _{b}} \times 100 = \frac{Nominal GDP}{Real GDP} \times 100
formula GDP Deflator
= \frac{\text{value of current output at P} _{t}}{\text{value of current output at P} _{b}} \times 100 = \frac{Nominal GDP}{Real GDP} \times 100
formula % of Nominal GDP
use when increases in inflation and GDP are stated in percentage terms: % of Nominal GDP = (1 + % Δ real GDP) (1 + % Δ inflation) - 1 % of Nominal GDP ≈ ( % Δ real GDP + % Δ inflation)
Statistical Discrepency
* The statistical discrepancy is the official “fudge factor” that ensures perfect equality between gross domestic product and gross domestic income in the National Income and Product Accounts . * “added” to gross domestic income when calculating GDP.
National Income
* income received by all factors of production used in generating all final output. * the sum of compenstation to employees, all profits (corporate and government) before taxes, interest income, rent, unincoroparted busienss net income and indirect busienss taxes less subsidies.
Capital Consumption Allowance
the depreciation measure for capital needed to produce output
Personal Income
* a measure of income and savings * all household income (earned or unearned) * an important measure of how much consumers can spend. = national income - indirect business tax - corporate income tax - undistributed business profits + transfer payments
Personal Disposable Income
* personal icome net of personal taxes * closely watched figure, shows how much households actually have available for spending.
Household Savings
= Personal Disposable Income - consumption expenditures - transfers to foreigners - interest paid by consumers
Aggregate Demand Curve
determined by aggregate income and current price levels where: 1) aggregate expenditures = aggregate income 2) the avaialable real money supply is willingly held by households and businesses
Fiscal Balance
= G - T where G = government spending T = taxes
formula Savings
S = I + (G - T) + (X - M) where: I = investment G = governement spending T = taxes X = exports M = Imports
three ways to consume private savings
1) investing 2) financing government deficits (where T >G) 3) running a trade deficit (M > X)
What is the implication of a fiscal deficit?
G - T < 0 must be sustained by having greater savings than investment rates and / or by running a trade deficit.
What is the impact of of an increase in real income on on aggregate consumption?
Aggregate consumption will increase.
What is the impact of a decrease in taxes on aggregate consumption?
Aggregate Consumption will increase.
Two factors that will increase aggregate consumption?
* an increase in real income * a decrease in taxes
Factors that determine investment decisions
* the level of real interest rates * aggregate output / income
Government spending is tends to be independent of:
economic factors such as interest rates and economic activity.
Taxes collected are dependent on:
* the level of economic activity * net taxes are positively related to aggregate income.
What is the relationship between aggregate income and net exports
higher income leads to a greater demand for imports.
what is the relationship between aggregate income and net taxes and imports?
Higher aggregate income increases net taxes and imports.
Fiscal Balance
= G - T where: G = gov spending T = Taxes
Trade Balance
= X - M where: X = exports M = imports
What is the relationship between income and the fiscal balance and the trade balance?
As income rises the fiscal balance and trade balance decrease.
The level at which savings exceeds investing is dependent on
* the real interest rate * higher rates will induce people to save more * lower interest rate will induce more investing as it is less beneficial to save in low-rate environments.
IS Curve
* the relationship that equates expenditures with interest rates. * Considers how interest rates impact saving and investment * does not consider the appropriate level of interest rates or the price levels in the market.
Assuming the real money supply is constant, an increase in real income must create an:
* increase real interest rates * so as to keep the demand fro money equal to the supply * known as the LM curve
The IS curve slopes:
* downward * there is an inverse relationship between savings and investment.
the LM curve slopes
* upward. positive slop * positive relationship between income and interest rates
Aggregate Demand Curve
the intersection of the LM and IS curves
what type of relationship exists between price level and real income
inverse relationship
Aggregate Supply Curve is the
* level of output that companies will produce at various prices. * supply curves can be viewed as short-term or long-term
what is the assumption regarding capital and technology in the short term?
capital and technology are fixed in the short term
The short term aggregate supply curve is affected by:
* resource prices and production costs * inflation * supply shocks
long-term aggregate supply is impacted by
* changes to the supply of resources (including labor) * improvements to productivity and technology * institutional changes that improve efficiency of resource use
What serves to ‘ration’ or allocate scarce goods and resources ?
Prices serve to ration or allocate scarce goods and resources to people who are willing to pay the highest price.
What does scarcity necessitate? What does scarcity result in?
* scarcity necessitates rationing * scarcity results in competition
Law of Demand
a rise in the price of a good will cause consumers to buy less of the good because they now have greater incentive to seek and use substitutes.
Derived Demand
* demand for factors or production * demand for factors of production is derived from the demand for goods and services.
formula Aggregate Production Function
Y (quantity of GDP supplied) = F ( L, K, T)
where: L = Labor Quantity K = Capital T = Technology
The Long Run Aggregate Supply shows
the relationship between the quantity of real GDP supplied and the price level over the long run, when real GDP = potential GDP
Increases in long-run aggregate supply (LAS) is caused by:
* an increase in the supply of resources * an improvement in technology or productivity * institutional changes that increase the efficiency of resource use.
Decreases in long-run aggregate supply (LAS) is caused by:
* a decline in resources (including labor) * a decline in the level of technology available * a shift in the institutional arrangements that reduce productivity and the efficiency of resource use
Productivity
* the average output produced per worker in a certain time frame * measured in terms of output per hour worked
How is productivity typically measured?
in terms of output per hour worked
The Short-Run Aggregate Supply shows:
the relationship between the quantity of real GDP supplied and the price level
Short Run Aggregate Supply Increases are due to:
* a decrease in resource prices/ production costs * a reduction in the expected rate of inflation * favorable supply shocks
What is the impact of economic growth on SAS and LAS
* both SAS and LAS shift outward, to the right * output expands and unemployment stays at its natural rate * if the money supply remains as is the price levels will fall
What is the impact of unanticipated increases in aggregate supply?
* lowers the price level and increases current GDP * in the long run aggregate supply does not increase because the unanticipated change is not expected to continue
What is the impact of unanticipated decline in aggregate supply?
* output declines (SAS shifts left and prices rise * if a decline in supply is permanent, LAS contracts with SAS, forcing the economy to stabilize at a new lower output equilibrium *assumes economy is at its long-run potential at the time of the decline.
What is the impact of persistent inflation in the short run.
it will be incorporated into long-term contracts which affect production costs in the short run.
Increases in Long Run Aggregate Supply (LAS) are caused by:
* increase in the supply of resources * improvement in technology and productivity * institutional changes that increase efficiency of resource use
Decreases in Long-run Aggregate Supply (LAS) are caused by:
* a decline in resources (including labor) * a decline in the available technology * a shift in institutional arrangements that reduce productivity and the efficiency of resource use.
Increases in short fun aggregate supply are caused by
* a decrease in resource prices / production costs * a reduction in the anticipated inflation rate * favorable supply shocks
What is the impact of economic growth on SAS and LAS
* shift outward (toward right) * output expands * unemployment stays at the natural rate * price levels fall (if the money supply does not change) *applies to anticipated changes in aggregate supply
What is the impact of an unanticipated increase in aggregate supply.
lowers the price level and increases current GDP.
What is the impact of a temporary decline in supply?
output declines (SAS shifts left) and prices rise.
What is the impact of a permanent decline in supply?
LAS contracts, along with SAS, forcing the economy to stabilize at a new, lower output equilibrium.
What is the long run impact of an unanticipated increase in supply -
In the long run aggregate supply… does not increase because the impetus to the supply rise is not expected to be repeated. large portions of the temporarily higher income is saved, money supply is expanded, loanable funds increase, interest rates fall, expenditures on interest sensitive capital goods and consumer durables rise
What is the impact of persistent inflation?
it will be incorporated into long-term contracts, which affect production costs in the short run.
What is the impact if actual and expected inflation rates are equal
there will be a persistent price increase for both goods and resources.
What is the impact if actual inflation is less than the anticipated inflation rate.
it is equivalent to a reduction in the price level when there is price stability or zero inflation.
What is the impact if the actual inflation rate is greater than the anticipated inflation rate?
* this will be equivalent of an increase in the price level. * goods and services prices will increase relative to resource prices, with firms expanding output and employment.
Aggregate Demand Curve
isolates the impact of price level on the quantity of goods and services through consumption, investment and net exports.
formula Aggregate Demand Y =
Y = C + I + G + X - M where: Y = quantity of real GDP demanded C = real consumption expenditure I = investment G = gov expenditures X = exports M = imports
Aggregate Demand is impacted by
* inflation (price levels) * expectations about the future * global economic conditions * fiscal and monetary policy
Aggregate Demand curve shifts tot he right due to:
* increase in real wealth * lower interest rates * increased optimism about the future * increase in expected future inflation * increase in income abroad * decrease in the exchange rate
What is the impact of an increase in real wealth on aggregate demand?
demand for all goods increase AD shifts right (Consumption Increases)
What is the impact of lower interest rates on aggregate demand?
* borrowing is less expensive therefore investment increases * increased investment causes AD to shift right
What is the impact of increased optimism about the future on aggregate demand?
* current investment increases * AD curve shifts right
What is the impact of an increase in the expected future inflation rate on aggregate demand?
* people are incented to increase spending today, consumption increases. * AD curve shifts right
What is the impact of increased income abroad on aggregate demand?
* exports demand increases * AD shifts right
What is the impact of a decrease in the exchange rate on aggregate demand?
* export demand increases. * AG shifts to the right.
What causes aggregate demand to decrease (AD curve shift to left)?
* real wealth declines * increase in real interest rate * pessimism about future demand * decline in expected future inflation * a decline in foreign income abroad * and increase in the exchange rate
What is the impact of an unanticipated increase in aggregate demand?
* causes output to increase, unemployment will fall (because of the time lag between the increased demand and an increase in resource prices.) * lag increases profits and output increases * resource prices catch up (increase), supply moved inward, new equilibrium is established at a higher price at the natural rate of unemployment at the economy’s long-run potential output
Impact of unanticipated decline in aggregate demand
* resource prices lag ahead of falling prices * output contracts below long-run potential * unemployment rises above the natural rate * lower prices and excess supply are considered: * resource prices fall * output increases to long-run potential * unemployment returns to normal rate
What will cause AD curve to shift?
* household wealth * consumer and business expectations * capacity utilization * fiscal policies * monetary policies * exchange rates * growth in global economy
What is the impact of changes in Household Wealth on the AD curve?
* increases in household wealth increase demand, shift AD curve to the right. * decreases in household wealth decreases demand, shift AD curve to left.
Wealth Effect
* Impact of Household Wealth on AD curve. * Increases in Household Wealth increase demand, shift AD curve right * Decreases in Household Wealth decreases demand, shift AD curve left.
What is the impact of consumer and business expectations on the AD curve?
consumers confident in job prospects/income will spend more, increasing demand and shifting the AD curve to the right.
What is the impact of changes in capacity utilization on the AD curve?
* high utilization means that companies seeking to increase productions are forced to invest in operations. * Higher investment shifts AD curve to the right
What is the impact of changes in fiscal policy on the AD curve?
* higher government spending shifts AD curve right * higher taxation rates will lower demand and shift the AD curve to the left.
What is the impact of changes in Monetary Policy on the AD curve?
* raising interest rates means draining bank reserves and reducing the money supply. * shifts AD curve to left.
What is the impact of changes in exchange rates on the AD curve?
* depreciating currency will make exports cheaper and imports more expensive. * increases net exports and shifts AD curve to the right
What is the impact of changes in growth in global economy on the AD curve?
* global growth will tend to boost demand for a country’s exports. * AD Curve willl shift to the right
What will cause shifts in short-run aggregate supply (SRAS) curve (but not LRAS)?
* nominal wages * change in input prices * future price expectations * changes in business tax and subsidies * changes in exchange rates
What is the impact of changes in nominal wages on the SRAS curve?
* increase to nominal wages result in an increase in production costs. * supply is reduced, SRAS shifts to the left
What is the impact of changes in change in input prices on the SRAS curve?
* higher raw material prices increase the cost of production * reduce supply and shift SRAS curve tot he left
What is the impact of changes in future price expectations on the SRAS curve?
* own output price increases will increase supply and shift SRAS to the right. * this tends to be modest and temporary
What is the impact of changes in changes to business tax and subsidies on the SRAS curve?
* higher taxes increase cost of production, reduce supply and shift SRAS left. * higher subsidies reduce production costs, increase supply and shift SRAS to the right.
What factors impact both LRAS and SRAS?
* supply of labor * natural resources * physical capital * human capital * technology
LRAS is not impacted by
price level.
LRAS is determined by
the level of potential GDP
what is the impact of the supply of labor on LRAS?
larger sources of labor will improve production and shift LRAS to the right.
what is the impact of natural resources on LRAS?
* access to new source or improved access to existing sources results in higher production and shifts LRAS to the right.
what is the impact of physical capital on LRAS?
* growth in business investment improves the supply of capital which boosts production and shifts LRAS to the right
what is the impact of human capital on LRAS?
improving the quality of the workforce will increase production and shift LRAS to the right.
what is the impact of technology on LRAS?
technological improvements will boost productivity of the workforce, shifting LRAS to the right
Long-run GDP equilibrium occurs where
aggregate demand and supply curves meet
long run GDP equilibrium assumes
both labor and capital are fully utilized at equilibrium, so that in the long run equilibrium GDP equals potential GDP
A shift in the AD curve to the left will impact real GDP in what way
real GDP will contract and price levels will decline. lower demand, leads to lower company stock valuations and higher unemployment
what is the short term impact on GDP of an economic downturn?
equilibrium GDP declines below potential GDP.
Consumption demand stabilizes the economy and aggregate demand by
* decreasing less than income during an economic recession and increasing less than income during and economic boom * generally stable throughout a business cycle
How do changes in real interest rates help to stabilize aggregate demand and correct economic fluctuations?
consumer optimism causes greater current spending and decreases the supply of loanable funds – causes increases in interest rates, and investments diminish, and aggregate demand shrinks. under business pessimism, demand for investment funds decrease, interest rates fall, current consumption rises and the opp cost of investment falls
How do changes in real resource prices help correct economic fluctuations?
* if output is temporarily greater then FE capacity, prices rise and supply falls * if output is temporarily less than capacity, excess supply and high unemployment reduce resource prices so supply rises, and output rises to FA with lower prices.
When is short-run equilibrium achieved?
when the quantity of real GDP demanded is equal to real GDP supplied.
When is long-run equilibrium achieved?
when real GDP is equal to potential GDP
If AS and AD increase at the same rate then:
GDP growth is achieved without inflation.
An equilibrium below full employment is one where:
potential GDP is greater than real GDP
How do changes in real interest rates impact aggregate demand under consumer optimism?
- help to stabilize aggregate demand and correct economic fluctuations. - consumer optimism provokes greater current spending and a decrease in the supply of loanable funds. - this causes interest rates to rise, investments to diminish and aggregate demand to shrink.
How do changes in real interest rates impact aggregate demand under business pessimism?
- help to stabilize aggregate demand and correct economic fluctuations. - the demand for investment funds decrease, depressing the real interest rate. Current consumption rises, and the opportunity cost of investment falls. Aggregate demand then increases.
How can real resource price changes help to correct economic fluctuations when out put is temporarily greater then the economy’s full employment?
- if output is temporarily greater than the economy’s full employment, then prices rise, supply falls and the economy is restored to FE at higher prices.
How can real resource price changes help to correct economic fluctuations when out put is temporarily lower then the economy’s full employment?
- excess supply and high unemployment reduce resource prices so that supply rises, and output rises to FE at lower prices.
When is short term equilibrium achieved?
when the quantity of real GDP demanded is equal to the real GDP supplied.
When is long run equilibrium achieved?
when real GDP is equal to potential GDP.
What is the impact of aggregate supply and aggregate demand increasing at the same rate?
real GDP growth without inflation.
Long run aggregate demand is primarily affected by:
* the growth rate in the quantity of money. * if the quantity of money experiences a fast increase aggregate demand also increases - and there is high inflation
An equilibrium below full employment is one in which:
potential GDP is greater than real GDP.
A business cycle is caused by:
wage rates being slow to adapt and keep real GDP at potential GDP as aggregate demand and short-run supply vary
GDP is impacted by:
* Economic Growth - growth in quantity of labor, human and physical capital and technical advances. * Inflation - tendency for aggregate demand to rise more quickly than the increases in long-run supply. * the Business Cycle - occurs because aggregate demand don’t move at the same page
What is the primary reason for a persistent increase in aggregate demand and inflation?
the growth in the quantity of money
Recessionary Gap
the condition where equilibrium GDP drops below potential GDP.
What are the impacts to the economy of a recessionary gap?
* reduced corporate profits * lower commodity prices * lower interest rates * demand for borrowing
What is the best investment strategy during a recessionary gap?
* favor defensive companies * reduce exposure to cyclical and commodities * seek low-credit-risk investments * reduce riskier/more speculative investments * favor longer maturity investments over shorter maturities
Inflationary Gap
* When equilibrium GDP is greater than potential GDP * increase in AD (when supply does not increase) * temporary situation
How would a government intervene during an inflationary gap?
* higher taxes * lower spending * higher interest rates / reduction of money supply growth
What are the economic impacts during an inflationary gap period?
* higher profits * higher commodity prices * higher rates * inflation
What is the best investment strategy during an inflationary gap period?
* favor cyclicals and commodities * reduce fixed-income investments (especially longer maturity) * increase exposure to riskier investments overall * reduce defensive strategy
what is the impact of an increase in aggregate supply?
- high economic growth and very low inflation.
what is the impact of a decrease in aggregate supply?
* stagflation * both high unemployment and high inflation
Self correction is slower when dealing with?
changes in aggregate supply.
What is the best investment strategy when there is a decline in aggregate supply?
* favor equities * reduce fixed-income exposure (higher prices tent to raise interest rates) * raise exposure to commodities.
What is the best investment strategy when there is a increase in aggregate supply?
reduce exposure to commodities.
What is the impact of an increase in aggregate demand and aggregate supply?
* real GDP and employment will rise * if AD increases more than AS prices will rise * if AS increases more than AD prices will fall.
What is the impact if both AD and AS curves decrease?
* real GDP and employment will decline * If AD decreases more than AS prices will fall * If AS decreases more than AS prices will rise
What is the impact if AD increase and AS decreases?
* Prices will rise * If AD increase more than AS decreases GDP will rise * if AS decreases more than AD GDP will fall
What is the impact if AD decreases and AS increase ?
* Prices will decline * If AD decreases more than AS increases GDP will decline * If AS increases more than AD decreases GDP will increase.
Economic Growth
* the annual percentage change in real GDP
Five main drivers of economic growth:
- Labor supply 2. Human capital 3. Physical Capital 4. Technology 5. Natural Resources
The input of labor to growth is measured by:
* total hours worked. total hours worked = labor force x avg. hours worked per worker
Human Capital measures:
* the knowledge base of workers. * derived from education and experience. * countries invest in human capital education and health infrastructure
Physical Capital
* refers to property and equipment used to produce goods/services * used to drive GDP. higher investment in capital leads to higher GDP.
How does technology impact economic growth?
* makes it possible to produce new types of goods, produce more goods or produce higher-quality goods. * crucial to overcoming existing GDP limits.
Total Factor Productivity
the component that measures the impact of technology when attempting to assess the growth in GDP.
Natural resources impact to economic growth.
* raw materials needed for growth * renewable and non-renewable * provide certain countries with distinct advantages for boosting GDP. * not a prerequisite for high growth and income
formula Production Function
Y = A x F (L,X) where: Y = overall economic output A = total factory productivity (TFP), serves as a proxy measure for technological progress L = the quantity of labor K = the amount of capital
The production function specifies two main sources of economic growth:
- the accumulation of necessary input such as capital, labor, and natural resources 2. new technology that improves efficiency of use of inputs
Two main assumptions of the production function?
- constant returns to scale (i.e. if all inputs increase by the same percentage, the final output will increase by that percentage) 2. each input has diminishing marginal productivity (as any one input increase the impact to the final output will be incrementally smaller over time.)
