Q

Why do firms want to maximise profit

A

profit means firms can survive
Greater profits allow fims to offer better rewards to the owners pr shareholders or staff
Can be reinvested to make more profit later eg to expand

Q

Why is YED useful for firms and government

A

Can be used in sales forecasting if YED and changes in income are known.
Can be used in pricing policy - reduction in price for a normal good if there’s an expected fall in income

25
Why is XED useful for firms and governments
Tell them how to react to changes in the price of related products to ensure they maximise demand
26
Factors causing shift in supply curve
``` Changes to cost of production Technology Productivity Indirect taxes and subsidies Changes to the price of other goods Number of suppliers ```
27
Why is a high PES important to firms
Aim to respond quickly to changes in price and demand to make their supply as elastic as possible
28
How to firms make their supply as elastic as possible
Flexible working patterns Latest technology Spare production capacity
29
Why is supply price inelastic in the short run
Firms capacity may be fixed and at least one factor of production is fixed Firm can recruit more workers and buy more materials but it takes time to build additional production facilities. Can be difficult to increase production
30
Why is supply more price elastic in the long run
In the long run all factors of production are variable so is able to increase its capacity in the long run
31
Price mechanism
Allocated goods/services in an impersonal way. Prices will change until equilibrium is achieved and supply equals demand. Free from biases and opinions
32
3 functions of price mechanism
Acts as an incentives to firms - higher prices allow firms to produce more and increase production Signalling device- changes in price show changes in supply/demand and act as a signal Ration- high demand and supply is limited price will be high
33
Price mechanism advantages
Resources allocated efficiently to satisfy wants and needs Can operate without cost of employing ppl to regulate it Prices kept to the minimum as resources are used as efficiently as possible
34
Price mechanism disadvantage
Inequality in wealth and income Under provision of merit goods and an over provision of demerit gods Unemployment Public goods not produced
35
Consumer surplus
Difference between price that a consumer is willing to pay and the price they actually pay
36
Producer surplus
Difference between the price that a producer is willing to supply and a good or service at and the price they actually receive
37
Subsidies meaning
Money paid by government to the producer of a good to make it cheaper than it would be otherwise
38
What is division of labour
Type of specialisation where production is split into different parts and specific people are allocated to each task.
39
What is wrong with the barter system
Very inefficient, takes lots of time and effort
40
Three functions of money
Measure of value Store of value Method of deferred payment - money paid later
41
When does market failure occur
Allocates resources efficiently | Price mechanism fails to allocate scarce resources effeciently
42
Externalities meaning
third party effects arising from production and consumption of goods and services for which no appropriate compensation is paid
43
Factors influencing demand
``` The price of the good Consumer income Prices of other goods and services - substitutes,complimets Consumer tastes and fashion Other factors e.g. advertising ```
44
Which factors cause a shift in the demand curve
Changes in the price or availability of substitutes Changes in the price or availability of complements Changes in consumer income Changes in taste
45
What does the government do in a command economy
Reduce negative externalities Provide public goods Control demerit goods Supply merit goods
46
Factors affecting supply
The price of the good The impact of changing costs of production Technological progress Prices of other goods and services Government policy e.g. taxes and subsidies
47
Price elasticity of supply is determined by:
Price - an increase in price of a good, more supplied Substitutes - easier it is to switch production Time - at least one fix factor of production
48
Allocative efficiency meaning
consumer satisfaction is maximised in the production of goods and services
49
What are private costs
costs of consuming or producing goods or services that have to be paid for by third parties e.g. the individual or a firm
50
What are social costs
costs of consuming or producing goods or services that are paid for by society
51
When do we have negative externalities
When social costs are greater than private costs
52
Why may markets be inefficient
Externalities Missing Markets Under-provision of public goods Information gaps
53
2 characteristics of a public good
Non-rival | Non-excludable
54
What is a public good
one where its use by an individual does not stop | others from using it whilst its consumption does not reduce the amount available for consumption by others
55
When does market failure occur with public goods
A free-rider is someone who benefits from a good or service without paying for it With little incentive for firms to supply public goods, the government is likely to intervene
56
What is a private good
one where its use by an individual stops others | from using it whilst its consumption reduces the amount available for consumption by others
57
What is a quasi-public good
a private good that is similar to a pure public good but there is an ability to stop non-paying consumers from using it.
58
What is the intellectual property rights
By granting patents, copyright etc. the good becomes protected and therefore excludable
59
How can monitoring and control systems stop public goods
Restricting the use of a good by monitoring usage e.g. congestion charging or digital television
60
What is government failure
Costs of an intervention outweigh the benefits of intervention causes allocative inefficiency
61
Causes of government failure
Information failure Administrative costs too high Unintended consequences Regulatory capture
62
How subsidies may lead to government failure
If firms become used to receiving a government subsidy, they may have fewer incentives to cut costs and transform the business – they become reliant on subsidies and the government ends up wasting public funds on supporting inefficient firms. In the long-run, consumers end up paying higher taxes and higher prices
63
Tax meaning
compulsory contribution to state revenue, levied by the government
64
Benefits of indirect tax
Creates revenue which was be used of offset externalities | it will change the price immediately and allows the one functions of price to work ( eg consumers may ration)
65
Disadvantage of indirect tax
May have inelastic demand - eg price of fuel | Monetary value of negative externality can be hard to measure.
66
Advantage of subsidies
- In the long term, subsidies for a good will help change preferences. It will encourage firms to develop more products with positive externalities. - Enables greater social efficiency. Consumers end up paying the socially efficient price which includes the external benefit.
67
Disadvantage of subsidies
Difficult to estimate the extent of the positive externality. Therefore the government may have poor information about the service and how much to subsidise.
68
Why is there a dead weight loss of taxation
Reduces standard of living | prevent ppl from buying more
69
Tax incidence meaning
how the burden of a tax is distributed between firms and consumers
70
What are the reasons for government intervention
correct market failure achieve a more equitable distribution of income and wealth To improve the performance of the economy Stabilise prices Avoid excessive prices for goods with PE
71
How does factor immobility cause market failure and what do the government do
Structural unemployment, state investment in education and training
72
How does demerit goods cause market failure and what do the government do
overconsumption of products with NE | Information campaigns, minimum age from consumption
73
How does imperfect information cause market failure and what do the government do
Damaging consequences for consumers from poor choices | Statutory information / labeling
74
How does relative high poverty cause market failure and what do the government do
Low-income families suffer social exclusion, negative externalities Taxation and welfare to redistribute income and wealth
75
How does monopoly power in a market cause market failure and what do the government do
Higher prices for consumers causes loss of allocative efficiency Competition policy measures to encourage new firms into a market
76
Forms of government intervention in markets
Minimum prices Maximum prices Nudges/Behavioural unit
77
Assumptions of rational choice model
Consumers choose independently (not influenced) The consumer has fixed and consistent preferences They gather full information on alternatives Always make an optimal choice given prefrences
