Q

Classical theory/Say’s Law

A

Supply creates demand
When something is produced, it generates income equal to its value
Prices and wages are FLEXIBLE, they will adjust to ensure that everything is purchased, and recessions will always correct themselves
Assumes economy is fully utilizing its resources

Q

Why is the LRAS curve vertical in the long run?

A

An economy’s production (GDP) and growth is dependent on its avaliability of LLC and its ability to use those resources to create good, NOT on price level

Q

Sticky wage theory

A

SRAS slopes up because nominal wages are slow to adjust in the short run to the price level. A lower price level make employment and production less profitable, so firms reduce the Q of goods and services they supply

Q

Misperceptions theory

A

A lower price level causes misperceptions about relative prices, which induces suppliers to respond to a lower price level by decreasing QS of goods and services

22
Q

Things that will shift the SRAS

A
  • anything that shifts LRAS
  • Expectations about prices: increase in expected price level shifts SRAS left, decrease in expected price level shifts SRAS right
23
Q

The economy at equilibrium

A 
Full employment (has 5% enemployment)
Y=Max GDP, 5% unemployment, and max income
24
Q

Real GDP can only increase when…

Nominal GDP can only increase with…

A

Real GDP can only increase when an economy produces more output (goods and services)
Nominal GDP can only increase with an increase in price level

25
Q

To show a recession using AS/AD model, SRAS and SRAD must intersect

A

Below full emmployment level of output

26
Q

How to fix a recession:

A
  1. AD shifts left (could be due to a terrorist attack, bubble burst, bank failures)
  2. Prices and real GDP fall, economy is not producing at max potential output
  3. Over time, AS shifts right, people expect the price level to be lower
  4. Economy returns to Eq in the long run. Output remains at full employment in the long run, and the price level has fallen
27
Q

Productivity

A

Explains the large variations in living standards around the world. It is the amount of goods and services from each hour of a worker’s time

28
Q

A growth in productivity leads to…

A

A growth in living standards

29
Q

How is productivity determined?

A

Physical capital, human capital, natural resources, technology

30
Q

Physical capital

A

stock of equipment and structures used to produce goods and services.
Workers are more productive with more tools
Capitial is a factor of production used to make goods and services including more capital

31
Q

Human capital

A

The knowledge and skill workers acquire through education, training and experience.
Raises a nation’s ability to produce goods and services

32
Q

Natural resources

A

Inputs into the production of goods and services that are produced by nature. Either renewable or nonrenewable.

33
Q

Technological knowledge

A

Society’s understanding of the best ways to produce goods and services

34
Q

Importance of saving and investment for productivity

A

One way to raise future productivity is to invest in more current resources in the production of capital
If society wants to invest more capital, it must consume less and save more of its current income

35
Q

Diminishing returns

A

property where the benefit from an extra unit of an input declines as the quantity of the input increases
Workers who already have a large quantity in producing goods and services will only benefit slightly from an additional unit of capital, while workers with less capital will benefit largely with additional capital

36
Q

Catch up effect

A

Property saying that countries that start off poor tend to grow more rapidly than countries that start off rich

37
Q

In the long run, a higher savings rate leads to…

A

a higher level of productivity and income, but NOT to higher growth

41
Q

Capital stock, productivity and GDP contributes to the foreign country. GNP contributes to their own country’s

42
Q

How does investment abroad help a country grow?

A

It increases stock of capital, which leads to higher productivity and wages. It also helps poor countries use modern technology from richer countries

44
Q

Economic growth

A long run/sustained increase in real GDP

Developed countries aime for 2%-3% growth per year

45
Q

Productivity

A

The quantity of goods and services produced per worker

Determines a nation’s potential growth

46
Q

Factors that shift the labor demand curve

A

Any changes from MPxP
P: anything that changes the price of product (shifts in product market)
MP: anything that changes the MPL (technology, supply of other factors of production)

47
Q

What can increase a worker’s productivity?

A

Increases in

  • capital goods (stock)
  • human captial (skill)
  • natural resources
  • technological knowledge
48
Q

An increase in productivity leads to a shift of the LRAS…

A

Right, showing economic growth

49
Q

Globalization

A

Process of removing barriers to open the world into one single community

50
Q

Stagflation

A

Falling output and rising prices

No automatic fix

51
Q

Inflationary gap

A

The economy is operating BEYOND full employment level of output (unemployment us below natural rate)
Resources are working overtime
Inflation will eventually cause a leftward shift in SRAS
