Q

Rationing function of price

A
  • Allocates resources
  • When demand > supply, P increases, limiting consumption of those unwilling to pay a higher price
  • Viceversa if a surplus occurs

25
Signaling function of price
- Convey info about market's conditions and value of goods and services - Prices are high -> shortage of good -> resources should be diverted into that good - Viceversa for lower prices/oversupply
26
Incentive function of price
- Price determines consumer/producer behaviour - When prices are high, firms want to produce more, consumers buy less and viceversa
27
Consumer surplus
Difference between max amount a consumer is willing / able to pay for a good vs what they actually pay
28
Producer surplus
Difference between actual price received for a good vs price they were willing to accept
29
Marginal cost
Additional cost of a firm to produce 1 extra unit of output Supply
30
Marginal Benefit
Additional benefit received by a consumer from consuming an extra unit of a good. Max price a consumer is willing / able to pay for an extra unit Demand
31
Transitional economy
An economy transitioning from planned to free market through - Deregulation - Privatization - MArket liberalisation
32
Consumer rationality
When consumers makes choices based on taste and preference
33
Completeness assumption
Consumers know their preferences and can rank them
34
Transitivity assumption
If a consumer prefers good A over B, and B over C they will automatically prefer good A over C. Their taste is consistent
35
Non satiation assumption
Consumers will always prefer more of a good rather than less
36
Bias
Systematic error in thinking and decision making
37
Rule of thumb
- Simple / easy to apply decision making shortcuts - Thinking that higher price = better quality
38
Framing bias
- Way in which info is presented can affect one's perception - 50% chance of doubling initial investment rather than 50% chance of losing investment money
39
Anchoring bias
- Relying too heavily on the initial info provided - Buying a 50$ shirt rather than 100$ one even though both are expensive
40
Availability bias
- Giving more weight to easily rememberable / available info - Purchasing product advertised on a billboard
41
Bounded rationality
- Herbert Simon - Humans don't have unlimited capacity for processing information - Searching for information to maximise utility is costly - Instead of maximising, consumers will satisfice (satisfactory outcome > best outcome)
42
Bounded self control
- People exercise self control to certain limits - Consumers spend too much / save too little
43
Bounded selfishness
- People are selfish within limits - May want to contribute to a public good rather than maximising their own utility, sacrificing personal welfare
44
Nudge theory
- Behavioral economics - Individuals can be easily influenced by environment and choice presentation into making decisions via subtle changes called 'nudges' - No financial incentives, sanctions, choice limitations
45
Default choice
Choices made by default - Organ donation in Italy, France, UK are default
46
Restricted choice
Choices limited by gvt or authority - Speed limits, voting/smoking age
47
Mandated choice
Compulsory choice between alternatives - Deciding to donate organs, deciding to make a living will
48
PED
Measure of responsiveness of Qd for a good in respect to a change in price - Always negative due to law of Demand
49
Tax incidence
Who ends up paying a tax (tax shifting). In the case of an indirect tax consumers may pay the tax wholly or partially
50
Flat rate/specific tax
Same amount of tax per each unit sold - Usually per litre or kilo
51
Ad valorem tax
Indirect tax expressed as a percentage of price of a good
52
Primary commodities
Necessities w no substitutes, PED inelastic
53
YED
Measure of responsiveness of demand of a good with respect to a change in consumer income
54
PES
Measure of responsiveness of Qs with respect to a change in price - Always positive due to law of supply
55
Maximum price
When gvt sets a price below equilibrium, only prices below equilibrium are allowed not above. Increases availability and equality.
56
Minimum price
When gvt sets a price above equilibrium, only prices above are allowed. Protects and aids certain suppliers.
57
Indirect tax
Tax imposed on spending to buy goods/services Can be excise or on all/most goods VAT/IVA
58
Excise tax
Indirect tax imposed on particular goods (cigs, alc, petrol). Can be advalorem or specific.
59
Subsidy
Assistance by gvt to individuals or group of individuals to increase production or consumption of a good
60
Merit goods
Goods/services which are often undervalued and under consumed by consumers with positive externalities which are ought to be subsidised (education, health, renewable energy)
