Economists Use Models
Summary
TLDRIn this script, Benjamin Faust discusses the importance and limitations of economic models. He uses the analogy of a paper airplane and a toy store model to illustrate how models can be good for some purposes, like understanding structure or function, but not for others, such as appearance or practical use. Faust emphasizes the necessity of simplifying complex economic systems to study them effectively, encouraging viewers to embrace learning about economics.
Takeaways
- 𧩠The economy is complex and requires simplification for understanding and discussion, which is where models come into play.

Q & A
What is the main purpose of using models in economics according to Benjamin Faust?
-The main purpose of using models in economics is to simplify the complex economy to make it understandable, discussable, and thinkable.
How does Benjamin Faust describe the limitations of models?
-Benjamin Faust describes the limitations of models by comparing them to a paper airplane and a toy airplane. The paper airplane is good for simulating flight but not for looking like a real airplane, while the toy airplane looks like a real one but cannot fly.
What is an example of a model that is good for visual representation but not for functionality?
-An example of a model that is good for visual representation but not for functionality, as given by Benjamin Faust, is a toy airplane that looks like a commercial flier but cannot fly when tossed in the air.
What is an example of a model that is good for functionality but not for visual representation?
-An example of a model that is good for functionality but not for visual representation is a folded paper airplane, which can fly when launched but does not look like a commercial airplane.
Why does Benjamin Faust use the H2O molecule model in his explanation?
-Benjamin Faust uses the H2O molecule model to illustrate how a model can be good for understanding the structure of something but poor for understanding its dynamic behavior or effects, such as how water interacts with the human body or erodes stones.
What does Benjamin Faust suggest about the necessity of models despite their limitations?
-Benjamin Faust suggests that despite their limitations, models are necessary in economics because they help us study and understand complex economic systems.
What does Benjamin Faust imply about the relationship between the complexity of the economy and the use of models?
-Benjamin Faust implies that due to the complexity of the economy, which has many moving parts, models are essential tools to simplify and study economic phenomena.
How does Benjamin Faust encourage the audience to engage with the content?
-Benjamin Faust encourages the audience to engage with the content by expressing his love for learning and inviting the audience to like and subscribe for more content if they enjoy learning about economics.
What is the significance of the paper airplane model in understanding economic models?
-The paper airplane model signifies that economic models, like the paper airplane, may not perfectly resemble the real economy but can effectively demonstrate certain aspects, such as the principles of flight in the case of the airplane.
How does the toy airplane model contrast with the paper airplane model in terms of economic modeling?
-The toy airplane model contrasts with the paper airplane model by emphasizing the importance of appearance and structural accuracy in economic models, even if they might not capture the dynamic aspects of the economy.
What does Benjamin Faust mean when he says that models 'have limitations' in the context of economics?
-When Benjamin Faust says that models 'have limitations' in economics, he means that no single model can capture all aspects of the economy, and each model is designed to highlight specific features or behaviors, inevitably omitting others.
Outlines
đ« The Limitations of Economic Models
In this paragraph, Benjamin Faust introduces the concept of economic modeling by comparing it to the use of models in other contexts. He uses the analogy of a paper airplane to illustrate that models can be effective for certain purposes, such as simulating flight, but not for others, such as appearance. Similarly, a toy store model airplane may look like a real one but won't function as a flying object. Faust emphasizes that economic models are simplifications of the complex economy and, while they have their limitations, they are essential tools for understanding and studying economic phenomena.

Transcripts
my name is Benjamin Faust and today
we're going to talk about how do we
model things in the economy the economy
is very complicated you've got a lot of
moving parts and so we somewhat have to
simplify it in order to understand it to
talk about it to think about it so we
use models I've done a couple of samples
of models here let's say you're making a
model out of an airplane right here I
have a folded paper airplane and this
paper airplane is good as a model in one
way but not good in another way first of
all does it look like the kind of
airplane that you would fly if you were
flying commercial absolutely not so it's
not a good model as far as looking like
an airplane but it is a good model as
far as being able to give some distance
going when you launch it so it's an
excellent model perhaps for flight or
for part of a flight but it's a terrible
model as far as looking like it to
contrast that if you were to get a model
airplane from a toy store and make it
one pretty much identical to the
commercial fliers it might look like the
kind of airplane you take when you go
somewhere but it won't fly if you toss
it in the air
so models have limitations but we use
them because it helps us to study
economics here's another model this is a
model of an h2o molecule this molecule
is good because we can see the structure
of how water looks however is a poor
model if we're trying to see what water
does in action how it treats the human
body when it's when you consume it or
how water erodes stones over time but
it's a good model to see how it looks at
the very small level so in economics we
have various models we use and the
models we use have various limitations
my name is Benjamin Faust and I love
learning
I hope you do too and if you enjoy
