Q

3 components of Investment (by firms)?

A
  1. Business fixed investment (new capital goods like PPE)
  2. Residential investment (new homes)
  3. Inventory investment (value at eoy - beg)

(Financial investment like bonds and stocks not counted in GDP - does not produce products to capture investment.
Car counted as consumption not investment - value depreciates)

Q

How to calculate Income Approach to GDP?

Q

Why does GDP change over time?

A

Prices change & quantity of output changes

Adjusting for price changes:
- Compare GDP for diff years to see how much output changed, HOLD PRICES CONSTANT - outcome is called real GDP (if both output & price change - called nominal GDP)

  • Expect GDP to be higher over time - more ex, more goods produced due to technology
  • If produce more OUTPUT - economic growth - good
  • If GDP is higher cause PRICE increase means inflation - not good

Q

What is Real GDP? What is Nominal GDP?

A

Real GDP - BASE year price x current year output

Nominal GDP (current dollar value of production) - CURRENT year price x current year output

Q

Will nominal GDP exceed real GDP during inflation (prices increase)?

A

Yes. Nominal GDP uses current year price while real GDP uses base year price (constant).

Price increase - price used to calculate nominal GDP will be higher

Q

Why is Nominal GDP misleading?

A

Nominal GDP may exceed real GDP altho it produces less output BUT shows economic growth just cause PRICE increase - current (not base) year price x current year output

17
Q

Why is real GDP a flawed measure of well-being?

A

GDP omits and undervalues some goods & services

Only measures MARKET transactions
- omits illegal transactions, volunteer work, household production (not counted in GDP - may look poor but actually self-sufficient in poorer countries since grow and consume own crops)

Omits value of: (all these affect well-being but not captured in GDP)
1. LEISURE
2. INTANGIBLE PEOPLE VALUE (crime rates, traffic congestion)
3. UNDERGROUND ECONOMY (unreported legal, illegal, casual labor paid in cash like tutoring)
4. ENVIRONMENTAL QUALITY (produce more output but cause pollution)
5. INCOME INEQUALITY

18
Q

Formula for GDP per capita? (WELFARE MEASURE)

A

GDP/population

Shows: STANDARD OF LIVING
- material standard of living (more goods and services - more consumption)
- health and life expectancy
- education

19
Q

What is CPI (Consumer Price Index) and its formula?

A

A measure of COST OF LIVING during a particular period (change in consumer prices)

Current year cost / base year cost

(Cost of a STANDARD BASKET of goods and services. Base year for CPI normally changes every 5 years)

Eg base year (2013) cost $680
2014 cost $850
CPI = 850/680 = 1.25

Base year CPI alw 1
Cost of living in 2014 is 25% higher than 2013 (inflation rate)

20
Q

What is a price index?

A

Measures average price of GIVEN YEAR’S cluster of goods and services relative to the price of the same goods and services in a BASE YEAR

Depending on purpose:
- CPI - cost of living
- Producer price index - resources price
- Import/ export price index - traders

21
Q

What is a GDP deflator? What is its formula?

A

Measures prices of goods and services included in GDP

(Nominal GDP/ Real GDP) X 100%

22
Q

What is rate of inflation?

A

Annual % Change in price level (CPI)

If negative - deflation

23
Q

How to adjust for inflation? (Compare values over time)

A

DEFLATING NOMINAL qty converts it to a REAL qty (remove effect of price changes)

  • Divide nominal qty / price index (CPI)

^for each year, can compare $ that has more purchasing power in which year

24
Q

What is Real Wage? Formula?

A

Wage paid in terms of purchasing power

Real wage = Nominal wage / CPI

  • Nominal wage - how much dollars u earn
  • Real wage - how much goods and services u can buy with ur money
25
Q

What does indexing do?

A

Increases a NOMINAL qty each period by the % increase in a specified price index

  • prevents purchasing power of nominal qty from being eroded by inflation
26
Q

2 biases of CPI

A
  1. Quality adjustment bias
    (does not measure quality change)
  2. Substitution biases
    (CPI uses FIXED basket of goods and services, but consumers will not buy same qty when price increases - will switch to substitutes - failing to account for substitutes overstate inflation)
27
Q

What is noisy prices?

A

Buyers & sellers cant easily tell whether
- relative price of good is increasing or
- inflation is increasing the price of the good

response to changing prices is slow and costly since have to gather information

28
Q

What is bracket creep?

A

Occurs when household is moved into higher tax bracket due to increases in NOMINAL but not REAL income

(Higher tax brackets have higher tax rates)

Earn higher cause of inflation (inc by 10%) - may not be able to compensate higher cost of living (inc by 15%)

29
Q

Distortion caused by taxes - Does high inflation increase or decrease investment in PPE

A

Decrease

Capital depreciation allowance encourage purchase of capital goods eg govt allow u to keep $100 every year to buy $1k machine aft 10 years but it may not be $1k anymore

30
Q

What is the Shoe Leather and Menu Cost?

A

More frequent, smaller withdrawals cost:

Shoe leather costs - more trips to the bank

Menu costs - updating price changes

31
Q

What does unexpected redistribution of wealth result in?

A

If workers’ salaries are not indexed and inflation is higher than expected

  • Salaries lose purchasing power
  • Employers gain at the expense of workers
32
Q

What is real interest rate? Formula?

A

Annual % increase in PURCHASING POWER of financial assets

real interest rate = nominal interest rate - inflation
r = i - pie symbol

(If inflation unexpected and very high, real interest rate might be negative - helps borrowers and hurt lenders - when lend money actually suffer because for a given nominal interest rate, higher the inflation rate, lower the real interest rate)

nominal interest rate - annual % increase in DOLLAR value of an asset

33
Q

When real interest rate is high, as a lender, do you gain or lose more?

A

Gain

Higher real interest rate means that your returns retain more purchasing power after accounting for inflation, which increases the value of the interest you receive in real terms.

34
Q

What is the fisher effect?

A

The tendency for nominal interest rates to be high when inflation is high and vice versa
