Q

What is forgone consumption?

A

Q

What are the social costs of economic growth?

A

Worker’s skills may become obsolete as a consequence of economic growth since existing skills may not be needed in the future due to the new skills that are made.

Q

What is the supply of national saving positively related to?

A

It is positively related to real interest rate

22
Q

What does excess supply of saving do to the real interest rate and investment

A

It drives real interest rate down and encourages more investment

23
Q

What does excess demand for investment do to the real interest rate

A

It drives the real interest rate up

24
Q

What does a higher rate of investment lead to?

A

It leads to a higher growth rate of potential output

25
Q

What does an increase in the demand for investment do to the real interest rate? What does it encourage in households?

A

It pushes up the real interest rate and encourages more saving by households

26
Q

What does the higher rate of saving (and investment) lead to?

A

It leads to a higher growth rate of potential ouput

27
Q

Investment rates has a positive relationship with what?

A

With growth rates

28
Q

What is the aggregate production function?

A

GDP = FT (L,K,H)
L=labour
K=physical capital
H=human capital
T=technology

29
Q

What does the notation FT indicate?

A

That the function relating to L, K, and H to GDP depends on the state of technology

30
Q

What are the key assumptions that are made about the aggregate production function?

A

The aggregate production function displays diminishing marginal returns when any one of the factors is increased on its own
Constant returns to scale when all factors are increased together

31
Q

What do we assume of human capital and physical capital for simplicity? Of technology?

A

That they can be combined into a single variable called capital and that technology is held constant

32
Q

What is marginal product of labour?

A

It is positive and diminishing
MPL = ΔY/ΔL

33
Q

What is marginal product of capital?

A

It is positive and diminishing
MPK = ΔY/ΔK

34
Q

By adding one more input, what happens to other inputs?

A

They are constant

35
Q

When adding an additional amount of output, what happens to output?

A

What is being output becomes smaller and smaller

36
Q

What is the Cobb-Douglas production funtion?

A

Y = A x Lα Kβ where 0 < α,β < 1

37
Q

What is constant returns to scale?

A

Output increases in proportion to the change in all inputs as the scale of production is increased

38
Q

What does holding capital constant do?

A

Each additional unit of labour will eventually add less to total output than the previous unit

39
Q

What is labour-force growth in the Neoclassical model?

A

In the Neoclassical model with diminishing marginal returns, increases in population (with fixed capital) lead to increases in GDP but an eventual decline in material living standards

40
Q

What is physical and human capital accumulation in the Neoclassical model?

A

Capital accumulation leads to improvements in material living standards, but because of the law of diminishing returns, these improvements become smaller with each additional increment of capital

41
Q

What is balanced growth with constant technology in the Neoclassical model?

A

If capital and labour growth are the same, then GDP will increase
In the Neoclassical growth model with constant returns to scale, such balanced growth will not lead to increases in per capita output and therefor will not generate improvements in material living standards

42
Q

What is the hypothesis of the law of diminishing returns?

A

An increase in quantities of variable factors but used with fixed factors will make marginal product of variable factor eventually decrease

43
Q

What is the importance of technological change in the Neoclassical model?

A

Technological change is assumed to be exogenous
New knowledge can contribute to the growth of potential output, even without capital accumulation of labour-force growth

44
Q

What is embodied technical change?

A

It is when technological improvements are contained in the new capital goods

45
Q

What is endogenous technological change?

A

It is the idea that technological change is responsive to prices and profits, making it endogenous to the economic system

46
Q

Should workers be afraid of technological change?

A

No they should not be afraid of technological change since labour markets are likely to continue to adjust to changes in demand and supply for labour so the overall level of employment will grow in line with the population, independent of the rate of technological change

47
Q

How is growth achieved?

A

It is achieved through costly, risky, innovative activity that often occurs in response to economic signals
Learning by doing
Knowledge transfer
Market structure and innovation
Shocks and innovation

48
Q

What do Neoclassical theories of economic growth assume about investment in capital?

A

That it is subject to diminishing marginal returns

49
Q

What are the 2 categories of the sources of increasing returns?

A

Market-development costs
The Economics of Ideas (knowledge)

50
Q

What do advances in technological knowledge increase?

A

It increases resource efficiency

51
Q

What can growth help the world do?

A

It can help the world address many problems but further growth must be sustainable growth, which should be based on knowledge-driven technological change
