Q

Demand

A

The willingness and ability to buy quantity of a good given price and given time

  • Qd= A-bP
  • quanity

Q

Demand curve exogenous change

A

Happens outside the formula; marketing, willing to pay more for the product
- Moves down or up, whole graph
- Positve (moves to right)
- negative (downwards or left)

Ex. Vaccination not effective; shifts down (price lower and quantity

Q

Supply

A

- Positive slope (want so sell more)
- Qs= A +bP
- Directly related (generate surplus)

Q

Supply curve exogenous change

A
  • Outside of the formula; resources for example during covid

Supply curve moves left or right

Positive shock; moves to the right (down); finding a goldmine, quantity higher and price lower

Negative shock; to the left (upwards), cost you more fot he product (price higher for same product), quantity lower, price higher

Q

self efficacy and incentives

A

Only financial incentives work if individuals believed thay have he skillset to perform the behavior.

42
Q

choking under pressure incentves

A

Can increase stress and self-consciousnesses, even so that high skilled individuals are likely to choke or fail in their desired behavior

43
Q

advantages of incentive

A
  • Often care about short term effects; one shock behavior
    Drinking when pregnant, sex eduction, vaccination
  • Lot of different forms
44
Q

Disadventages incentives

A

People are heterogeneous and not every incentive is tailored

Think about:
- not everybody same discount rate
- Some prefer losses and some gains

54
Q

Effective communication - Lasswell and 5 W

A
  • Who (is the communicator?)

  • With what effect (effect)
55
Q

Who - Lasswell and 5 W

What -Lasswell and 5 W
Strategies for message design

A

Message tailoring
- Target group
- Personal relevance

Emotion; fear appeal (threat), disgust, humour

57
Q

Which (media) - Lasswell and 5 W

A

Which channels?
- exposure of a channel, who do you reach with it?
- How can different channels work togehter

e.i.; pamflets, social media. newspapers

58
Q

To Whom?- Lasswell and 5 W

A

also the intended audience
- target group?
- Do they have higher risks?
- What are their preferences

59
Q

With what effect (effect) - Lasswell and 5 W

A
  • What were intended outcomes
  • How to monitor effects of communication

Survet, RCT, likes shares, page visits, comments

60
Q

When not use information campaigns?

A

Intention action gap

61
Q

What is a better approach when the gap between intention and action is due to external barriers or practical issues?

A

When the intention-action gap is caused by external barriers or practical issues (rather than a lack of knowledge or awareness), it is more effective to address the actual context (cues in the environment)

Making it easier for people to act by removing obstacles and simplifying actions can lead to better outcomes.

62
Q

barriers for effective communication

A
  • Persuasion; alpha and omega
  • 4 faces of resistance; reactance, distrust, scrunity and slowness
  • PKM model (persuasion knowledge model)
  • Resistance coping behavioral; cognitive coping, emotional coping, behavioral (avoidance)
63
Q

Persuasion - Barrier for effective communication

A

Alpha; attempt to persuade by increasing approach forces

omega; by decreasing avoidance (reduce resistance)

64
Q

PKM

A

persuasion knowlegde model
- the target population has knowledge and also will influence the dynamics about campaigns with information

  • Target and agent
  • topic, persuasion, agent/target knowledge
  • Knowledge about persuasion attempts of the agent to the target
65
Q

How does a government can improve market outcomes?

A
  • Regulating common resources
  • Providing public goods
  • Remedying the effects of externalities and market power
  • Addressing behavioural biases
66
Q

Reasons to intervene as a government

A

Limiations of ind. desicion making
- Lack of information
- Devations from rationality (biases)

Conflicts between individual and social interest
- Allocation of finite resources
- externalities

67
Q

Individual interest vs social interests, why and when?

A

Individual self interested; why
- Social wellbeing decreased by individual self interested maximizing own wellbeing
- not taking account of impact on society by their behavior

By decisions about:
- Finite shared resources
- Externalities (actions unintended outcomes on others)

68
Q

Finite resources in healthcare, possible consequence

A

Overuse or sub optimal allocation of finite resources

e.g.
Overuse; AM
- overuse leads to resistance
- Socially nog preferable, individual beneficial
- Externalities

Suboptimal allocation; healthcare providers
- Limited doctors and time
- Individual preferences, only the wealthy get care (rational if additional becomes beneficial
- Additional care often less beneficial for richer

69
Q

negative externalities def + eg

A

An unpriced byproduct of production or consumption that adversely affects another party not directly involved in the market transaction
- Smoking
- polution
- Drunk drivers
- Infections covid 19

70
Q

positive externalities

A

An unpriced byproduct of production or consumption that positive affects another party not directly involved in the market transaction
- Vaccination
- Healthy habits motivate others
- Education

71
Q

tools for changing unhealhty behavior as government

A

Command and control policies; regulate behavior directly
- Limits consumption
- Impose price caps (plafond)
- Mandatory behavior

Market based policies; provide incentives consumers will choose solve problem on their own
- taxes and subsidies
- Pollution permits

72
Q

Taxes as instrument to correct for overconsumption; in picture

A
  • Buyers pay more (Pb)
  • Producers recieve less (Ps)
  • revenue; €T x QT (only at Qt)
  • loss of consumer and producer surplus (Qe- QT) (not sold because of tax
73
Q

Taxes as instrument to correct for overconsumption

A
  • Increase costs; lower the quantity supplied & demanded at equilibrium
    (elasticity results in spread of tax burden)
  • Revenue for government, but less than market that transactions in the deadweight loss would occur
74
Q

when is a tax more effective

A

Same government revenue, but smaller costs to taxpayers

75
Q

Costs of taxpayers

A
  • Administrative burden
  • Deadweight loss
  • tax payment itself
76
Q

Elasticity and taxes

A
  • More elastic; more payed by producers
  • Less elastic; payed by the consumer
77
Q

Subsidy

A

Increase the consumption of a good
- Increases consumption through government expenditure

  • Also adds some deadweight loss
  • total surplus increases, but by less than the government spends on the subsidy
78
Q

why deadweight loss subsidy

A

Overconsumption by lowering the price

  • Consumers buy more than they normally would, even if the product isn’t worth that much to them.
  • Producers make more than needed because they receive extra money from the government.
79
Q

Internalizing externalities

A

altering incentives so that people take account of the external effects of their action

80
Q

Internalizing - negative externalities graph

A

Negative externality = costs!!

  • Private costs (supply)
  • Private value (demand)

Through externalities costs for society is higher (secondhand smoking eg.)

  • social costs (private + external)
  • Supply curve upwards or left
  • lower quantity
81
Q

social costs - negative externalities

A

externalities - supply
- Private
- External

82
Q

External costs - negative externalities

A

value of the negative impact
on bystanders

83
Q

pigouvian taxes

A

Taxes equal to the external costs

84
Q

positive externalities

A

Positive externality = value!
- Private value
- external benefit

government should subsidy

85
Q

External benefit - pos externalies

A

value of positive impact on others)

86
Q

Private value - pos externalities

A

the direct value to buyers

87
Q

Social value optimal quantity - pos externalities

A

Left of Q: Social value > cost. Too little is produced.’

Right of Q: Cost > social value. Too much is produced.

At the optimal Q, social value equals cost, maximizing welfare.

88
Q

pigouvian subsidy

A

Subsidies equal to external benefits are called Pigouvian subsidies,

89
Q

Summary externalities

A

Negative externality
- market quantity is larger than socially desirable

Positive externality
- market quantity is smaller than socially desirable

Remedy
- Tax for negative externalities
- Subsidy for positive externalities

90
Q

determinants of demand of goods

A
  • Price of commodity
  • Prices of other commodities
  • The income of the individual
  • The preferences of consumer
91
Q

Elasticity of demand

A

how much the demand changes when there is a price change
- Percentage change demand / percentage change price

92
Q

inelastic demand

A
  • percentage change in price is greater than percentage change in quantity demand
  • Price elasticity less than 1 (-1) 0-1
  • If P goes up 1%, then Q (demand) goes down less than 1%
  • Graph is linear down steep
93
Q

Elastic demand

A
  • Percentage change in quantity demand is greater than percentage change in price
  • If P goes up by 1%, then Q(demand) goes down by more than 1%

–Graph is linear less steeper

  • Price change changes
94
Q

Perfectly Elastic Demand

A
  • 0
  • Price constant
  • horizontal line
  • Every price change no buyers
  • perfect competition; buyer can buy same product somewhere else against same price
95
Q

Elasticity taxes and demand

A
  • Higher elasticity taxes more effective in bringing demand down and less unhealthy behavior
96
Q

Tax revenue is higher when elasticity is

A

Low; necessary good

  • People keep on buying
97
Q

Inelastic demand if

A
  • good is a necessity
  • Time period is shorter
  • the smaller the number of close substituties
  • the more broadly defined the market (food market, prices up, no subsitutes)
98
Q

Behavior change and tax revenue

A
  • Inelastic; price little on demand, tax much revenue, but not effective in behavior change
  • Elastic; demand reacts to price, effective in behavior change not much revenue
99
Q

Cons to taxes

A
  • Subsitutes with similar impact are not taxed (cross border shopping)
  • Some good more often by lower income; increasing will only affect them
100
Q

regulations example

A
  • Price ceilings
  • Smoking bans
  • No alcohol to kids
  • Forbid sale of drugs
  • Forbid cigarette advertisement
101
Q

Price ceiling cons

A

Otherwise there was more supply

  • Shortages
  • Longer waiting lines
  • non price rationing (other than prices to distribute)
  • Poorer health outcomes
