- Children are shown a puppet show.
- There are two puppet actors, Sally and Anne.
- Sally hides a marble in a basket, then leaves the
room. - While she is gone, Anne takes the marble from the
basket and hides it in a box. - Where will Sally look for her marble?

will buy the latest Harry Potter book, or add
brie to your shopping cart this week?
4- Most of economic theory presumes that decision
makers are rational they correctly conceive of a
well-defined set of alternatives, have
well-defined preferences, and choose a best
alternative. - Psychologists, sociologists and political
scientists believe that all action is
fundamentally 'rational' in character and that
people calculate the likely costs and benefits of
any action before deciding what to do. - This approach to theory is known as rational
choice theory.
5Economic behavior is a fundamental component of
human nature. In particular, it is rooted in the
observation that all human beings have a natural
interest in behaving economically.

7One way of doing this is by introducing to your
methodology Theoretical Paradigms, Conceptual
Designs, Prototypes, Precedents, Exampes
and/orModels

8Economic models serve to simplify data, to
forecast probable economic activity and to
demonstrate best policy choices.
9Models can provide a scheme to demonostrate your
knowledge of the ideal organizational
operations/structures.
10This particular model is based on Adam Smith It
is mostly used as an economic model but as you
can imagine has implications for Social
Responsibility.
Customer Satisfaction
TransparencyOpen and Honest Exchange of
Information
11It is not usually applied to IR but does have
implications for freedom, rights and democracy.
Improved economic and social services
An increase in freedom Freedom of Association
12It is helpful to your commitee if you create such
a model yourself or use one that is established
as a precedent.
13The Bar Chart is another popular way of
displaying your basic research methodology.
14Flow Charts are also very effective models.
15Mean (average), Median (most scores were equally
above and below this point, Norm (most frequent
scores).

16In economics rational behavior means that
individuals maximize utility under the
constraints they face.
Initially students have always thought of
negotiating as like a tug of war! In other words
they think of negotiating as an effort to
maximize utility.
17Utilility can be hard to dispute because it often
means the greatest good for the greatest number
of people. Some will get hurt but the utility
benefits outweigh the utiliity costs.We
sometimes use the Ford motor company as an
ethical example of using this type of model.
18As anticipated some cars suffered the defect by
exploding into flames.
1911 x 12.5 million autos137 million
- Probability
- Statistical probability showed that solving the
defect could save 180 deaths (and/or as many
serious injuries) it could also prevent 2100
vehicles from burning. However the total
savings from the prevention would be 49.15
million dollars. Ford estamated-on the basis of
utility-that is was not worth it to spend 137
million to save a possible cost of 49.15
million. The took the risk and produced the car
with the defects.
20Another paradigm for negotiating is Game Theory

22Game Theory has serious implications not only for
business but also for IR.
- Cooperation creates more benefits, refusal to
cooperate creates momre threats.
23Russia tests new ballistic missile
NATO has thoughts of bringing their Missile
Defense System to Eastern Europe. It is a complex
and ever evolving web of interlinked weapons and
radar based on land, sea, air and in space.
24The international interactionsand politicies we
observe at the macro-level (e.g., wars, trade,
terrorism) are driven by factors, events and
decisions that occur at the micro-level (e.g., in
war elite decision-making, domestic politics,
culture, state alliances, and so on).
- The tool that political scientists use to make
sense of this complexity is modeling. - One such popular model is Game Theory.
- You may have heard of game theory if you have
seen the movie A Beautiful Mind, a biographical
account of an important game theorist, John Nash,
or if you have ever watched the TV show Numbers,
in which Charlie (Professor of Mathematics) helps
his brother Don (FBI agent) solve crimes using
mathematical models or game theory.
25IR also assumes strategic interactions among
rational actors, who are trying to act according
to how they think their counterparts will act
and/or react.
- Within every society culturally defined
principles of justice and law serve to generate
internationally consistent expectations of how
political games are played and these coordinating
principles are strengthened by the assummption
that they are socially constructed to be in
harmony with (universal) natural law.
26Game Theory Methodology
- Game theory methodology assumes that
international transactions involves a group of
individuals (whom we call players). - Each players actions can be predicted on the
basis of probability theory. - However predictions are determined on the basis
of deciding whether or not statees (autonomous
regions) will act on the basis of interests,
policy (treaty) or cultural values.
27Understanding Consumer Behavior
28The Psychology of Consumer Behavior
- The Problem
- What markets are you trying to reach and what
will attract their interests/attention. - What media would reach them most efficiently?
29The SolutionConsumer Psychology
- Survey. Interview to collect informatioin about
attitudes, opinions, experiences, perceptions and
behaviors which are suspected to relate in some
way to your business interests. Getting the
right questions, and asking them in the right way
is pivotal - and especially difficult. - Statistical analysis. There are many strategies
for isolating segments from each other and
demonstrating the connection. - Psychological profiling. It is one thing to
discover that certain groups of individuals give
similar responses on certain key questions in a
survey. It is quite another to figure out who
these people really are what the underlying
psychology is that makes them think and feel and
act as they do. creators. To make profiles that
accurately reflect the segments, while making
them "come alive" as people, takes a lot of
creeativity, art and science.
