32
Q

Pricing and quantity

A
  • Lower prices increases consumption (quantity)
  • Higher pays leads to more demand for labour and effort
33
Q

Social norms sorts

A

Descriptive norms

Injunctive/ prescriptive norms

34
Q

Descriptive norms

A

beliefs about what others actually do
- Commonly done

35
Q

Injunctive norms

A

beliefs about others think we should do
- Socially acceptable

36
Q

Which norm is more likely to affect behavior

A

Bicchieri & Xiao (2009) - Discriptive
Stok, de Ridder, de Vet & de Wit - Descriptive

What people actually do around is stronger incentive for behavior

37
Q

Contradicting theather and law of demand

A

When something is free high quantity is expected

But social norms

38
Q

Market norms and social norms

A
  • Market norms; introduce cost benefit thinking with a budget, taking much more
  • Social norms; drive behavior and norms when there is no price tag and taking less
39
Q

pay enough or don’t pay at all

A
  • Low payments for task (cost beneift thinking and effort reduces)
  • Non- financial rewards also social norm thinking
40
Q

Power of free

A

Without financial rewards we are more likely to base our decisions on social norms

Well-known in marketing, giving away something for free creates a feeling of
reciprocity (Cialdini, 1993)

41
Q

Making something free

A
  • Changes people preferences (even when there is a transaction to be made)
  • Free does not mean an increase in quantuty
42
Q

Meaningfull and meaningless jobs

A
  • Payment but also meaningness added to work
  • Less meaning less effort

Pay not the only thing driving more labour

43
Q

IKEA effect

A

cognitive bias; a cognitive bias in which consumers place a disproportionately high value on products they partially create

  • Working hard on something increases you appreciation
  • Willingness to pay increases as you made it yourself
  • Own labour leads to increased value up to pair with expert
44
Q

Labour supply - rational perspective

A

Pay more employees work harder

More work requires more compensation

45
Q

What explains IKEA effect

A

Cognitive dissonance
- justification of behavior; gap between actions and thoughts
- After actions you beliefs change
- IKEA; actions already must be nice

Completion; you succeed in your task you like it more

46
Q

Homo economicus behavior does not only respond to price changes but also to:

A
  • Social norms (descriptive)
  • Monetary incentives can change behavior such that increasing pay decreases effort (boring task and Israeli study); too low pay
  • We change our preferences at prices around zero
47
Q

zero price effect

A
  • Something is free changes peoples preferences
  • Chocolate bars
  • Also when transaction cost with free has to be made
48
Q

Variables

A
  • Independent variable
  • Dependent variable
49
Q

Independent variable

A
  • exposure variable
  • manipulated variable

Manipulated by scientist

50
Q

Dependent variable

A
  • Outcome variable
  • Response variable
51
Q

different types of hypotheses testing

A
  • interviews
  • participant observations
  • observational data
  • survey research
  • experiments; can find a causal effect
52
Q

experiments

A
  • sample of population
  • control over extraneous variables
  • Manipulation of independent variables
  • Random assignments (true effect of intervention, not the cause of chance as the chances are the same)
53
Q

When not use experiments

A
  • Unethical questions; hunger and mortality
  • natural variation; sex varies naturally, you cant have control over it, cant manipulate sex
    Relies on natural variation
54
Q

population, element, sample and census Rotterdam

A

pop; All people in Rotterdam

Census; all people in rotterdam included

Element; one person in rotterdam

Sample; part of people in rotterdam

55
Q

Questions before assuming causality

A
  • Is sample representive?
  • Could the effect have occured by chance?
56
Q

Sampling techniques

A
  • Simple random sampling
  • stratified sampling
  • Convenience sampling
  • quota sampling
57
Q

Simple random sampling

A

Each member of population has equal chance of being sampled

Probability sampling; every member same chance

58
Q

Simple random sampling pro and cons

A

Pro;
- Most likely to lead to a representative sample

Cons:
- Expensive and might be impossible to obtain full list op population
- list must be kept up to date
- Responses rate might below and cause issues

59
Q

Stratified Random Sampling

A
  • Focuses on strata
  • Selection of individuals still random
  • random sampling within strata, group represents parts of population
  • Randomization within strata

Non probability sampling; not every member same chance

60
Q

Stratified Random Sampling pro and cons

A
  • Allows more targeted sampling and can be utilized to directly compare
    strata (at a small loss of representativeness)

Cons:
* Similar practical issues as with random sampling

  • Only representative if response rates are acceptable (at least we now know
    where they are centered
61
Q

Convenience sampling

A

Use a sample that is conveniently reached and available
- During classes
- Recruitment
- Asking on campus

62
Q

Convenience sampling pro and cons

A

Pro:
* Simple, quick and easy way of sampling
* Often in universities systems are in place to facilitate this form of sampling

cons
* Serious issues with generalizing to populations (i.e. very likely a
overrepresentation of some groups)
External validity not good

  • Example: a) Newspaper polling their readers, b) recruitment via own social
    media, c) university labs
63
Q

Quota Sampling

A

Quota based on knowlegde of the proportion in the population randomly assigning people to strata and then a convience sample
- Not random
- Strata
- Convience sample

64
Q

Quota Sampling pro and cons

A

pros
* Simple, quick and easy way of sampling
* Allows gathering a sample that is representative-like

cons;
* Non-random sampling still could have error

65
Q

condition

A

A condition is a specific part of an experiment where the effect of the independent variable on the dependent variable is tested or measure

66
Q

between subjects

A

Condition assigned to one group and compare the outcomes
- There are different groups !

67
Q

Within subjects

A

Each subjects complete multipele conditions
- One group to condition A and then move to B

68
Q

Between subjects

A
  • No learning effects
  • Shorter sessions
  • Easier to set up and randomize
69
Q

Within subjects

A
  • Possible learning effects
  • Fewer respondents needed
  • Fewer noise (random error)
70
Q

control condition

A
  • No manipulation of independent variable
71
Q

Condition assignment

A
  • Chance of aspects must be the same
  • So there is no noise
  • Purely the effect of the intervention
72
Q

Internal validity

A

Experiment proves that the changes in the independent variable are really causing the changes in the dependent variable,

  • High experimental control
  • Reliable measures
  • good data quality

LAB

73
Q

External validity

A

means how well the results of an experiment can be applied to or generalized to real-world situations or other groups of people.

  • Representative samples
  • Dynamic context
74
Q

Conventional lab experiment

A
  • a conventional lab experiment is one that employs a standard subject pool
    of students, an abstract framing, and an imposed set of rules

We invite students to the lab, and they receive the instructions

75
Q

Artefactual field experiment

A

an artefactual field experiment is the same as a conventional lab
experiment but with a non-standard subject pool (real people), but lab

Representative Tilburg citizens are recruited at the municipality center,
invited to a lab on site and asked to read the instructions on site

76
Q

Framed field experiment

A

a framed field experiment is the same as an artefactual field experiment but
with field context in either the commodity, task, or information set that the
subjects can use

  • Other environment, but awareness of experiment
77
Q

Natural field experiment

A

is the same as a framed field experiment but
where the environment is one where the subjects naturally undertake
these tasks and where the subjects do not know that they are in an
experiment.

not knowing experiment

78
Q

From field to lab

A
  • subject (from students to real individuals)
  • Environment (lab to home)
  • Awareness of experiment)
