A

YES

21
Q

What is the formula for each firm’s value added approach of GDP?

A

Value of Goods and Services - value of intermediate goods and services it used up

For gdp have to sum everything up

22
Q

What is the income approach ?

A

sum of value added = sum of factor incomes

Wages, Interest, Rent, Profit

23
Q

What is the formula for percentage change?

A

Growth rate = rate of change per unit time = (Current – Previous) / Previous

24
Q

Why must we use Real GDP?

A

filter out the impact of price changes

25
Q

What are the steps to use chain linked method?

A

For any two adjacent years (previous, current), compute growth rates via fixed-base method, using previous year prices

Then, choose a base year (a.k.a. reference year)

Use the growth rates to compute RGDP for all other years, with the reference year GDP as the anchor

26
Q

What are the 2 problems of gdp?

A

Measurement problems

Problems with using GDP as an indicator of well-being

27
Q

What are some measurements problem of GDP?

A

(changes in quality, higher quality should be counted as more production)

Underground economy: hard to obtain, affected by changes in data reporting and legality

28
Q

What is inflation rate?

A

% change in price level per unit of time

Or if use cpi:
New cpi -old cpi / old cpi

29
Q

What is the formula of CPI of current year, given cost of basket in current and base year?

A

CPI= 100 X (cost of basket in current year/ cost of basket in BASE year)

30
Q

How to calculate the real value givevn the nominal value?

A

Real value= Nominal value x (100/CPI)

31
Q

What is in basket of goods and services for EU worldwide cost of living index ?

A

160 items consumed by expatriate households

New york city as base city

32
Q

What is the fisher equation?

A

Real interest rate= nominal - inflation rate

33
Q

What are some problems of using CPI?

A

Substitution bias and outlet bias

Quality change bias (ok to pay more for higher quality products) and New goods bias (products tend to fall in price and improve quality IN EARLY YEARS)

33
Q

What is substitution bias?

A

If price of good a increase faster than good b, then people buy less of good a and more good b. (Substitution)

34
Q

Does cpi inflation rate understate actual inflation experience

A

FALSE
OVERSTATES ACTUAL INFLAITON EXPERIENCE (upward bias)

35
Q

What is outlet bias

A

As prices increase, consumers shift purchases from more expensive mainstream stores to cheaper discount outlets and online retailers (online retailers less represented in statistical authorities)

36
Q

What is the inflation goal?

A

inflation predictable, low, and positive

37
Q

Inflation does not destroy average purchasing power. T/F

A

True. BUT CAN LEAD TO REDISTRIBUTION OF POWER

38
Q

Why shoyld we keep inflation predictable?

A

reduces unintended redistribution of purchasing power

39
Q

How to correct for inlation when it comes to loans?

A

indexed to inflation

make loan agreement where nominal interest rate is ir + cpi inflation rate

40
Q

How is high inflation costly to society?

A

can distort relative price signals, causing misallocation of resources

seller changing price often means high menu cost

shoe leather costs from minimising money holdings

41
Q

Why is deflation bad?

A

In anticipation of lower future prices, households and firms may postpone their purchases

loan defaults and bankruptcy increase, economic activity disrupted

42
Q

What are the 3 types of unemploymenet and what?

A

frictional unn- in between jobs or entering labour market (made worse if gpvt proivide unn insurance)

structural unn- skill mismatch, geographic mismatch, labour market impediment(high min wage etc)

cyclical unn- flucturation in unn from change in production over business cycles

43
Q

What is full employment?

A

zero cyclical unn

other types still present

44
Q

What are the 2 labour utilisation indicators and formula

A

labour force participatiopn rate: labour force/able to work

employment rate: employed/able to work

45
Q

What are U-4 to U-6 rate?

A

U-4: (unn +discouraged)/ (employed+ unn + discouraged)

U-5: (unn+ discourageed+ marginally attached)/ (employed+ unn + discouraged + marginally attached)

u-6: (unn+ discourageed+ marginally attached + INVOLUNTARY PART TIME)/ (employed+ unn + discouraged + marginally attached)
