Q

Define PPF

A

PPF - shows the maximum possible output combinations of two goods in an economy, assuming full and efficiency employment of resources

Points on the PPF are productively efficient (all FOP are fully employed)

Inside PPF = productive inefficiency

Q

What does the PPF show?

A
  • Concept of opportunity cost - more capital goods produced means more consumers goods must be given up

Q

Define diminishing marginal utility

A
  • As individuals consume more units of a good or service, the additional units give successively smaller increases in total satisfaction

Q

Define choice architecture

A
  • Influencing consumer choices by the way choices are presented e.g. govt requiring people to opt out of organ donation (general has significantly higher % of pop. willing to donate)

Q

Define framing

A
  • Influencing consumer choices by the way words and numbers are used - e.g., presenting life insurance payments as less than £3 per day rather than £1000 per year

Q

Define nudges

A
  • Influencing consumer behaviour via the use of gentle suggestions and positive reinforcement e.g., the 5-a-day campaign to encourage greater consumption of fruit and veg can change behaviour in a sociably desirable manner

Can be more cost effective rather than laws, bans or regulation

Can compliment rational policy methods (e.g. using adverts to reinforce social norm)

Q

Define restricted choice

A
  • Giving consumers a limited number of options recognising that too much choice can sometimes paralyse individuals from making an effective choice with savings

Q

Determinants of demand

A

PASIFIC

Population
Advertising
Substitutes
Income
Fashion and taste
Income tax
Compliments
20
Q

PED equation

A

%change Qd/% change P

21
Q

YED equation

A

% change Qd/% change Y

22
Q

XED equation

A

% change in Q of good X/% change in P of good Y

23
Q

Define normal good

A

Rise in income leads to increase in demand.

24
Q

Define inferior good

A

Rise in income leads to fall in demand

25
Q

Define substitute

A

Positive - rise in price of one good increases demand for another

26
Q

Define Complement

A

Negative - rise in price of one good decrease demand for another

27
Q

Total revenue equation

A

Price x quantity

28
Q

Relationships between PED and firms’ total revenue

A

Price elastic D = fall in P increases TR
Price inelastic D = fall in P decreases TR
Price elastic D = rise in P decreases TR
Price inelastic D = rise in P increases TR

EOIS

Elastic - opposite - Inelastic - same

29
Q

Determinants of PED

A
  • Substitutes
  • % of income
  • Luxury/necessity
  • Addictive/habit forming
  • Time period
30
Q

Determinants of supply

A

PINTS WC

Productivity - Indirect tax - no. of firms - technology - subsidy - weather - Costs of production

31
Q

PES equation

A

% change Qs/% change P

32
Q

Determinants of PES

A

PSSST

Production lag - Stocks - Spare capacity - Substitutability of FoPs - Time

33
Q

Define joint demand

A
  • Goods that tend to be demanded together, i.e., complimentary goods
34
Q

Define joint supply

A

When the production of one good leads to the production of another good e.g., the production of beef and leather

35
Q

Define composite demand

A

When a good is demand for more than one distinct use

Therefore - rise in D for one of the distinct uses reduces the supply available for other uses

36
Q

Define derived demand

A

When a particular good or FoP is necessary for the provision of another good or service

E.g., a rise in demand for healthcare will likely increase the demand for doctors and nurses

37
Q

Define competitive demand

A

Substitute goods - similar to each other + rival (in competition with each other)

38
Q

Difference between normal and supernormal profit

A

NP - minimum level required to reward the entrepreneur for taking a risk and therefore to stay in a particular line of business

SNP - over and above NP

39
Q

Role of profit in a market economy

A
  • An important driver of business activity - creates an incentive for entrepreneurs to take a business risk
40
Q

Assumptions of perfect competition

A
  • Few, if any, barriers to entry or exit
  • Consumers and firms have perfect knowledge
  • Products are homogenous
  • Many buyers and sellers

Price takers (firms unable to influence ruling market price and thus have to accept it)

41
Q

Impact of the features of perfect competition

A
  • Any firm that tries to sell its product at a price higher than the market equilibrium will not make any sales (since consumers will know about cheaper alternatives)
  • Since all products are identical consumers have no loyalty to any particular firm
  • Therefore - all firms must accept the market price if they are to remain in the market
42
Q

Price determination in highly competitive markets

A
  • If other firms become aware that existing firms in the market are earning SNP, which they can easily do due to perfect info, they will enter the market easily due to the low barriers to entry
  • Increases overall supply in the market - leads to rightward shift of supply which reduces the equilibrium price
  • Increase in supply and reduction in price will occur up to the point at which only NP is made (only most competitive firms survive in the market)
43
Q

Perfect competition in the long run

A
  • Firms are productively efficiency (lowest point on AC curve) and allocatively efficient (where p = mc)
  • Price consumers pay for a good or service = cost of producing the last unit of output
  • Optimum allocation of society’s resources
44
Q

Advantages of perfect competition

A
  • Productive efficiency - any firm that doesn’t achieve this will lose its market share to rival firms that can produce the same product more cheaply
  • Allocative efficiency - lead to firms producing what consumers demand - since, if they don’t, they will lose market share to firms that are producing the most desired products
45
Q

Characteristics of monopolistic competition

A
  • Many buyers and sellers
  • Similar products that are differentiated from one another (e.g. by branding or quality
  • Barriers to entry and exit relatively low
  • Good information
  • Non-price competition

Firms are price makers

46
Q

Examples of monopolistic competition

A
  • Independent fast-food takeaways
  • Plumbers
  • Hairdressers
