Q

What are marginal returns of labour?

Q

What is the law of diminishing marginal returns (also known as the law of diminishing marginal productivity)?

A

A short-term law which states that as a variable factor of production is added to a fixed factor of production, both the marginal and eventually the average returns to the variable factor will begin to fall

25
What is variable cost?
The cost of production which changes with the amount that is produced, even in the short run
26
What is total cost?
All the cost incurred when producing a particular size of output
27
What is average variable cost?
Total variable cost divided by the size of output
28
What is marginal cost?
Addition to total cost resulting from producing one additional unit of output
29
What are average fixed costs?
The total cost of employing the fixed factors of production to produce a particular level of output, divided by the size of output
30
What are average total costs (average cost)?
The total cost of producing a particular level of output, divided by the size of output
31
Where are the short-run and long-run cost curves derive from?
Short/long-run production theory
32
What are short-run costs made up of?
Fixed costs and variable costs
33
What are economies of scale?
As output increases, long-run average cost falls
34
What are diseconomies of scale?
As output increases, long-run average cost rises
35
What are the internal economies and diseconomies of scale?
Changes in long-run average costs of production resulting from changes in the size or scale of a firm or plant
36
What is external economy of scale?
A fall in long-run average costs of production resulting from the growth of the market or industry of which the firm is a part
37
What is external diseconomy of scale?
An increase in long-run average costs of production resulting from the growth of the market or industry of which the firm is a part
38
What can technical economies of scale be caused by?
Indivisibilities, the spreading of research and development costs, volume economies, economies of massed resources, economies of vertically linked processes
39
What are some of the various types of economies of scale?
Technical, managerial and finance-raising economies
40
What are some of the various types of diseconomies of scale?
Communicational failure and motivational diseconomy of scale
41
In cost theory what are economies and diseconomies of scale often respectively caused by?
Increasing and decreasing returns to scale (in production theory)
42
What is total revenue?
All the money received by a firm from selling its total output
43
What is average revenue?
Total revenue divided by output
44
What is marginal revenue?
Addition to total revenue resulting from the sale of one more unit of the product
45
What is perfect competition?
A market that displays the six conditions of: a large number of buyers and sellers; perfect market information; the ability to buy or sell as much is desired at the ruling market price; the inability of an individual buyer or seller to influence the market price; a uniform or homogeneous product; and no barriers to entry or exit in the long run
46
What is a monopoly?
One firm only in a market
47
When do marginal and average curves plotted from the same set of data always display the following relationship?
- When the marginal is greater than the average, the average rises - When the marginal is less than the average, the average falls - When the marginal equals the average, the average is constant, neither rising nor falling
48
What is a price-taker?
A firm which is so small that it has to accept the ruling market price. If the firm raises its price, it loses all its sales; if it cuts its price, it gains no advantage
49
What is a price-maker?
When a firm faces a downward-sloping demand curve for its product, it possesses the market power to set the price at which it sells the product
50
What is a quantity-setter?
When a firm faces a downward-sloping demand curve for its product, it possesses the market power to set the quantity of the good it wishes to sell
51
What is revenue?
The money that a firm earns when selling its output
52
What does the nature of a firm's revenue curves depend on?
The competitiveness of the market struvture in which the firm sells its output
53
In perfect competition, what are the average and marginal revenue curves like?
Horizontal
54
In monopoly where do the average revenue curve and the marginal revenue curve?
The average revenue curve slopes downward and the marginal revenue curve below the average revenue curve
55
What is normal profit?
The minimum profit s firm must make to stay in business, which is, however, insufficient to attract new firms into the market
56
What is profit?
The difference between total sales revenue and total cost of production
57
What is profit maximisation?
Occurs at the level of output at which total profit is greatest
58
What is abnormal profit (also known as supernormal profit and above-normal profit)?
Profit over and above normal profit
59
What are the roles in a market economy?
Creating incentives, rewarding innovation and risk taking
60
What is technological change?
A term used to describe the overall effect of invention, innovation and the diffusion or spread of technology in the economy
61
What is invention?
Making something entirely new; something that did not exist before at all
62
What is innovation?
Improves on or makes a significant contribution to something that has already been invented, thereby turning the results of invention into a product
63
What is productive efficiency?
For the economy as a whole occurs when it is impossible to produce more of one good without producing less of another. For a firm it occurs when the average total cost of production is minimised
64
What is dynamic efficiency?
Measures improvements in productive efficiency that occur in the long run over time
65
What is monopolistic competition?
A market structure in which firms have many competitors, but each one sells a slightly different product
66
What is duopoly?
Two firms only in a market
67
What is creative destruction?
Capitalism evolving and renewing itself over time through new technologies and innovations replacing older technologies and innovations
68
What is technical progress?
Applying scientific and engineering knowledge, as it develops, to produce goods which are more efficient and work better
69
What is creative destruction?
A process through which capitalism evolves and renews itself over time through new technologies and innovations replacing older technologies and innovations
