Q

three principles on how choices are made

A
  1. preferences are dynamic
  2. given a series of choices, there is more than one way to frame the possible options
    - local approach
    - global approach
  3. individuals always choose the better option
    - local choice
    - global choice

Q

local choice

3. principle on how choice is made

A

best option is item that has currently higher value

–> e.g. value of drug would always be chosen over non drug activity

Q 
global choice
(3. principle on how choice is made)
A

–> e.g. would lead to abstinence = drug was never chosen

Q

Local equilibrium

A

Choosing the behaviour that gives you the most reward at the moment

“I think I would like to eat Chinese food tonight, its almost my favourite”

  • current values of the two meals are the same
  • overall preference for Chinese food
  • how people actually make choices

–> SUBOPTIMAL = hypothetical dinner ate too often Chinese food (overconsumption)

Q

Global equilibrium

A

“I find that dining out is more pleasurable when I don’t always go to my favourite restaurant. I save it for when I really want a great meal”

  • the point at which the curve shows the value of each possible meal plan attains its maximum value
  • overall preference for Italian food
    how economists say choices should be made

–> OPTIMAL choice (economist view)

Q

‘matching law’/melioration

Q

Traditional Economic Theory

A

assumes people behave ‘rationally’

–> seek info on quality, cost, options & properly use this to maximise utility

Q

Limitations of Traditional Economic Theory

A
  • assumes that people are NOT influenced by advertisements
  • -> bc they already know what makes them best off
  • bounded rationality: people actually face cognitive limitations –> use shortcuts and heuristics, rather than classic utility-maximising behaviour
  • traditional economics does not address the decision-making process

– > this theory often poor art explaining behaviour

Q

Behavioural Economic Theory

A
  • acknowledges that people oftentimes do NOT act rationally (in economic sense)
  • make myopic (kurzsichtig) decisions
  • do not necessarily learn form mistakes

Q

Prospect Theory

A

theory of individual economic risk taking behaviour

    • ppl risk averse with regard of prospective gains
    • risk seeking in face of large losses

Q

Nudging

A

People should be given choices (libertarian idea), but should be guided by experts (paternalistic idea)

  • ppl often do NOT make decisions in their best interest
  • so need to be nudged towards better decisions

Q

Status quo bias

A

preference for the current state of affairs

20
Q

Loss aversion

A

heightened tendency to focus on avoiding losses, even if it entails to engage in risky behaviour (framing is important)

21
Q

overly discounting the future

A

e.g. in case of smoking, exaggerating pleasure (overweighting the present) & underestimating future (health) costs

22
Q

decision fatigue

A

phenomenon of ego depletion

23
Q

Behavioural Economics in intervention of Tabasco use

A
  1. encouraging people to sign contracts to quit smoking & prove rewards if they do so
  2. encourage use of electronic cigarettes

–> behavioural idea= easier to get people to engage in related behaviour than to eliminate habit completely

24
Q

Behavioural Economics in intervention for obesity

A

School Cafeterieas

  • fruits rather than sweets and fatty snacks near cashier
  • salad bars
  • giving choice of veggies
  • close ice cream freezer
  • sweets have to be paid cash instead of using lunch card
25
Q

Principles of Behavioural Economics

A
  • Demand

- Discounting

26
Q

Demand

A

the amount of commodity (Ware) purchased at a given price

  • it is described on basis of elasticity of demand
  • demands can be graphed via demand curve (shows consumption as function of price)
  • unit price
27
Q

elasticity of demand

A

proportional change in consumption relative to proportional change in price

  • inelastic
  • elastic
28
Q

inelastic

elasticity of demand

A

consumption rel. insensitive to a price change (e.g. food)

29
Q

elastic

elasticity of demand

A

consumption relative sensitive to a price change (e.g. drug)

30
Q

unit price

A

demand analysis quantifies the effect of price on consumption

31
Q

reinforcer interaction

A

demand is important for the choices that drug-dependent people will make to obtain the reinforcer

  • reinforcers can be substitutes (e.g. butter &margerine)
  • complements (e.g. soup & soup crackers)
  • can be independent (e.g. soup & butter)
32
Q

opportunity costs

A

refers to situations where options are mutually exclusive

e.g. choosing one master’s program renders other choices unavailable

33
Q

Discounting

A

determines how much value a reinforcer loses as a function of a manipulated variable

  • delay
  • probability
  • social distance
34
Q

delay (temporal) discounting

A

examines the extent to which the value of a reinforcer decreases as a function of its temporal distance

  • e.g. getting 100 euros now va after 1 month delay
35
Q

exponential discounting

A

if a larger-later reward is preferred when both, it and smaller-sooner reward, are distant in the future

  • e.g. far in the future but option 50 euros still sooner vs larger 100 euros
36
Q

probability discounting

A

determines the degree to which uncertainty of a reinforcer decreases the value of that reward

  • e.g. delayed + uncertain reward (health)
    vs immediate and certain reward (drug)
37
Q

social discounting

A

determines the degree to which a person’s valuation of a reinforcer delivered to another person (family, stranger) decreases a function of the social distance between those individuals

–> e.g. close individual (family, friend) vs distal individual (stranger)

38
Q

law of demand

A

consumption of most commodities (Waren), including psychoactive substances, is inversely related to price or response requirement

39
Q 
contingency management (CM)
(intervention)
A

attempts to change the user’s environment such as:

  • substance use + abstinence are readily detected
  • abstinence is readily reinforced
  • substance use results in loss of reinforcement
  • the density of reinforcement derived from substance-free sources is increased

CM interventions have been modified & are specifically successful if:

  • relatively low-value vouchers are delivered probabilistically
  • when access to paid employment is used to reinforce abstinence
40
Q

Interventions to reduce Bad habits

A
  1. contingency management
  2. reducing availability of substance
  3. increasing real or perceived cost of substance
  4. community reinforcement approach (CRA)
  5. behavioural couples therapy (BCT)
  6. Brief motivational Interventions
  7. Restructuring environments to enhance access to healthy choices
  8. substance-free activity sessions
  9. fading procedures
  10. contracts including deposit contracts
  11. pharmacological approaches to impulse control
    12 executive function training (WM training)
41
Q

Community Reinforcement Approach

A

focuses on assisting individuals to develop alternative reinforcement that is mutually incompatible with substance use
- includes counselling

42
Q

Behavioural Couples Therapy (BCT)

A

attempts to increase the cost of substance use through the use

  • of daily sobriety contracts - - ingestion of disulfiram
  • by encouraging significant others to withhold reinforcement (if substance abusing partner drinks or uses substance)
43
Q

Brief Motivational Interventions (BMIs)

A
  • attempts to increase individuals motivation to change
  • -> in part by fostering individuals awareness of costs & consequences of substance use
  • discussion of pros and cons of substance use
  • personalised feedback that highlights tangible costs of use
  • removing drugs & associated paraphernalia (pipes, needles…) from home to remove triggers
  • direct or indirect alleviation of withdrawal symptoms
44
Q

Substance-free activity sessions (SFAs)

A

aims to enhance motivation to pursue stated goals (in BMI) & provide a specific and personally tailored roadmap to achieve future goals

  • as part of BMI –> e.g. 50 min SFA followed by BMI session
  • targets substance-free activities & temporal discounting
  • include personalised feedback
45
Q

Behavioural economics

A

refers to the hybridisation of concepts and methods from psychology & economics to understand ppls choices
