Q

Three definitions of GDP

A

measure of aggregate output

Production perspective:
1.GDP is the value of the final goods and services produced in an economy during a given period.
2. The sum of the value added to the economy during a given period.
Income perspective:
3. The sum of incomes in the economy during a given period

Q

Real GDP

A

quantity of goods produced x constant price level
Explanation (GDP adjusted for inflation):
A base year with certain prices is taken and only the changes in quantity and not price levels are taken into consideration.

  • called: GDP in terms of goods, GDP at constant prices
  • -> economic growth often defined as % change in real GDP

Q

average price level of goods

A

aggregate price level

The best measure of the aggregate price level is probably the GDP price index.

The GDP price index is the ratio of nominal GDP to real GDP multiplied times 100.

Q

When is the economy overheating?

A

When inflation increases and operates above its potential

What Is an Overheated Economy?

An overheated economy is one that has experienced a prolonged period of good economic growth and activity that has led to high levels of inflation (from increased consumer wealth). This sharp rise in prices causes inefficient supply allocations as producers overproduce and create excess production capacity in an attempt to capitalize on the high levels of wealth.

Q

exogenous variables

A

taken as given; I has a line above it, indicating that it is exogenous

34
Q

Which variables describe fiscal policy?

A

T, G; the choice of taxes and spending by the government.

35
Q

Which variables are exogenous?

A

I, G and T

36
Q

Why are G and T exogenous?

A
  1. Governments do not behave with the same regularity as consumers or firms.
  2. G and T are chosen somewhat arbitrarily by the government
37
Q

Why is the symbol Y used for both production and income

A

Because GDP can be looked at from the production side and from the income side. Production and income are identically equal.

Y is used for GDP

38
Q

balanced budget of the government

A

taxes equal government spending

39
Q

What is autonomous spending?

A

Part of the demand for goods that does not depend on output or income.

40
Q

Is autonomous spending usually positive?

A

Yes it is.
Only if government were running a very large budget surplus - if taxes were much larger than government spending - could autonomous spending be negative.

41
Q

What is the effect of the multiplier?

A

Any change in autonomous spending (from a change in investment, to a change in government spending, to a change in taxes) will have the same qualitative effect: it will change output by more than its direct effect on autonomous spending.

for example the Co increases by 1 billion which is part of the autonomous spending, than the output Y is increased by more than 1 billion

42
Q

Saving

A

the sum of private and public saving

43
Q

government budget surplus

A

if taxes exceed government spending

44
Q

budget deficit

A

if taxes are less than government spending

45
Q

two equivalent ways of stating the condition for equilibrium in the goods market

A 
Production = Demand
Investment = Saving
46
Q

(1-c1)

A

propensity to save

47
Q

IS relation

A

‘investment equals saving’:
what firms want to invest must be equal top what people and the government want to save

in a modern economy investment decisions are made by firms, whereas saving decisions are made by consumers and the government.

48
Q

Measures form aggregate production/income

A
  • economic growth
  • recession
  • stability and growth pact (SGP)
49
Q

What is SGP?

A
  • Government deficit max 3% of GDP

- Government debt max 60% of GDP

50
Q

economic growth

A

increase in production of goods

51
Q

shortcomings of GDP as measure of total production

A

What is not taken into consideration:

  • Production households
  • shadow economy
52
Q

shortcomings of GDP as measure of well-being

A

What is not taken into consideration:

  • Leisure
  • Health
  • Eduction
  • Environmental pollution
  • Crime
  • Income distribution
53
Q

Lorenz curve

A

shows the inequality in income distribution

  • A perfect equality is displayed by a straight line
  • the Lorenz curve shows that for example 40% of the households only earn 25% of the income and this means there is inequality.
54
Q

Alternative measures for well-being

A
  • Human Development Index (HDI)
    (factors: health, education, living standards, incorporates GDP)
  • Well-being Index
    (Career-, Social-, Financial, Physical-, Community-wellbeing)
55
Q

Necessary steps to determine the effect of fiscal policy in goods market

A
  1. GDP
  2. Demand for goods
  3. Supply of goods
  4. IS relation (=equilibrium condition in goods market)
  5. Effect of change/”shock” on equilibrium
  6. Fiscal policy
56
Q

Second hand bike produced in 2015 and sold in 2016. Which year is the bike in GDP calculation?

A

2015

57
Q

Effect of “shock” on equilibrium in goods market

A

changes in autonomous spending lead to change in equilibrium income

58
Q

ceteris paribus

A

all other factors constant

59
Q

Suppose firms will invest an additional amount of 1 billion

Is this a shift in the curve or a movement along the curve?

A

It is a shift in the curve, because I belongs to autonomous spending which is changed. This leads to a change in Z (demand) due to change in autonomous spending, given Y.

60
Q

How is fiscal policy incorporated in the IS-model?

A

Fiscal policy is G (Government spending) and T (Taxes)

Goal is:

  • stimulate/slow down economy
  • employment

Influence aggregate demand:

  • expansionary policy (G increases and/or T decreases)
  • contractionary policy (G decreases and/or T increases)
61
Q

Limitations of fiscal policy (General)

A
  • Delay macroeconomic data
  • Expected data could differ from actual data
  • Policy can be implemented too late
  • Fiscal policy cannot be implemented as fast as monetary policy
  • Crowding out
62
Q

Current limitations of fiscal policy

A
  • government deficit
  • government debt
  • Stability and Growth Pact (SGP)
63
Q

Please explain briefly the concepts of inflation and deflation and what impact each of these
might have on consumers and the economy as a whole.

A

inflation is a sustained increase in the general price level of goods and services in an economy over a period of time . Deflation is a decrease in the general price level of goods
and services. High or unpredictable inflation is harmful to the economy as it adds inefficiencies and makes it difficult for companies to budget or plan long-term. High inflation also redistributes income. It also increases the price of exports. High deflation, on the other hand, causes a transfer of wealth from borrowers and holders of illiquid assets, to the benefit of savers and of holders of liquid assets and currency, and because confused
pricing signals cause underinvestment by firms.

64
Q

Please, provide a formal definition of the concept economists rely on to measure consumer
prices. What are the two main issues that arise when calculating that index?

A

To measure the average price of consumption, i.e. the cost of living, economists look at the Consumer Price Index. The index is the value of a basket of consumer goods (produced locally and abroad) in terms of prices accessible to consumers. The two issues in
calculating CPI are related to (i) the quality of goods in the economy varies over time, and
(ii) the weights assigned to different goods and services in the basked change over time.

65
Q

What is not counted in GDP

A

illegal activities

and household activities

66
Q

GDP and GNP differenct

A

GDP is only for the domestic market

GNP is about nationality so when for example an American produces something in Germany it counts as GNP

67
Q

In period 1 The intermediary good was produced with a market value of 20$ and in period 2 the final good with 50$ worth.

What is the GDP contribution in period 2?

A

The contribution is 30$ in period 2.

68
Q

What is investment in economics?

A

Investments can be made by firms and households.
Investment by firms:

  • capital equipment
  • inventory
  • structures

Investment by Households:
- new homes

69
Q

What is consumption in economics?

A
  • Any expenditure on final goods or services by households except for new homes.
70
Q

value add approach of GDP. What is summed up?

A

the incremental values added in production are summed up

71
Q

A U.S. car rental company spends $1m to buy 30 new Fords that were made in the US. What changes in the formula for GDP?

A

Investment increases by $1m.

72
Q

You buy 100,000 of IBM stock. What changes in formula for GDP?

A

No impact, because it is not consumption and no investment. Investment is only made by a firm or when consumers buy a new house in something new produced. No consumption either because it is not used up.

73
Q

Microsoft buys $100m of IBM stock. What changes in formula for GDP?

A

No impact. Investment is only made by a firm in something new produced. Stocks are no new product.

74
Q

The Social Security Administration makes a $2000 payment to a retiree. What changes in formula for GDP?

A

No impact. It is no government expenditure but a transfer only. Nothing new is produced.

75
Q

The Social Security Administration buys a new accounting system for $1m

A

Government spending increases by $1m. GDP increases by $1m.

76
Q

What can you find out when looking at the GDP?

A

Economic activity and size and influence of an economy.

77
Q

Was GDP ever intended to measure wellbeing?

A

No, It was a way to approximate production

78
Q

Clearly explain how this inflation is measured.

A

Inflation is percentage change in the price level as
measured by Consumer Price Index (CPI)/bundle of
goods for households or consumers.

79
Q

Clearly explain
what core inflation is and how it differs from (general)
inflation.

A

Core inflation = inflation excl. volatile categories like

food and energy

80
Q 
Name two (and
not more than two) limitations of fiscal policy.
A

Delay macroeconomic data, Expected data could
differ from actual data, Policy can be implemented too
late, Fiscal policy cannot be implemented as fast as
monetary policy, Crowding out, Rules regarding Stability
and Growth Pact (SGP) (Government deficit max 3%
of GDP, Government debt max 60% of GDP)

81
Q
