Alright folks, welcome to a semester in economics.

And what we're going to do in this very first lesson is we are going to define economics

and try to get an understanding of what it is exactly, this subject that we're learning.

So you should have a notebook in front of you

or some paper so that you can take notes and I recommend

that you write down everything

that I write down up here on the board in your notes

so that you can study and add a few extra notes of things

that I say or maybe some things that will trigger memories while you're learning this stuff, okay?

So what is economics?

Well I have my own definition, there's probably several definitions out there, I'm sure there are plenty of textbooks that have definitions of economics.

Well there's one in particular that I like to work from and I'm going to give you that definition right now.

And after I give you that definition, so we're going to say economics.

What is economics?

All right.

After I give you my definition, I'm going to break down the definition into four main pieces

so that you can have a better understanding of how we're going to focus on learning this semester.

Okay.

So here's my definition of economics.

To me, economics is the scientific study of how individuals,

that's like people, right?

Individual people.

Organizations.

So that's like businesses or maybe government organizations or not -for -profit organizations.

You know, groups of people who come together to either make a profit or achieve some kind of goal.

Or, let's say, or societies.

Now, a society is like an entire country or an entire city or an entire state.

Okay, change that to a societies

or societies deal with the problem of scarcity.

Scarcity.

Okay, that's S -C -A -R -C -I -T -Y.

Scarcity.

That word right there, scarcity, that is the main word in economics.

That is the most important word in economics.

If I were to give you a much simpler definition of economics, I would just simply say it is the study of scarcity.

And I'm going to talk about scarcity in just a few minutes.

So there are four main elements of this definition.

The first thing I want to tell you is that economics itself is scientific.

that it focuses on individuals, organizations, and societies.

So that's its own one category.

Economics has to do with how these groups or individuals, how they deal with.

Now, the idea of dealing with is the idea of making a decision.

When you want to deal with something, when you get a flat tire, you have to deal with that flat tire.

And what that means is to make decisions about how to handle that flat tire.

So dealing with is the idea of decision making.

Having to make a decision.

A decision about what?

Well, a decision about the fact that you are facing the problem of scarcity.

You as an individual are facing the problem of scarcity.

Or an organization is facing the problem of scarcity or an entire society, a country, or a state,

or a city, is facing the problem of scarcity.

And like I said, I'm going to define scarcity in just a little bit.

Okay, so here are the four things we're going to focus on.

Is economics as scientific, economics as focusing on individuals, organizations, and societies, economics as dealing with decision making,

and economics as handling the problem of scarcity.

So in order to do that, what I want you to do right now is I want you to, on your notes, in your paper, I'm going to break up the board into four quadrants,

like this, four quadrants.

And I think you should also break up your notes into four quadrants.

And we're going to put each one of these subjects in each one of these quadrants.

So economics is scientific.

So we're going to talk about what that means.

Economics is concerned with individuals and organizations.

or firms, and societies, whole, large groups of individuals.

That economics focuses on dealing with, deal with, what does it mean to deal with something?

Okay?

And then lastly, we have the problem of scarcity.

The problem of scarcity.

Okay?

So we're going to take these one at a time in the order that they are in the definition.

So economics is scientific.

Alright, so economics is a science.

There are scientific journals animals devoted to economics.

There are people, researchers, people who get paid lots of money, well they probably don't get paid as much as they want to get paid,

but nonetheless, there are people who get paid money just to do research on economics, research on the problem of scarcity,

research on individuals, organizations, and societies and how they deal with the problem of scarcity.

And because economics is scientific, there are certain things that go along with all science.

And two of those things that we're going to focus on, we're not going to do all of science, but the two main things I want you to understand is that in science,

when we approach a subject in science,

we have to make assumptions and we have to draw conclusions.

We make assumptions and we draw conclusions.

Now I want to clarify something here, and that is this class is a principles of economics class.

This is not some masters or PhD level class where we're going to dig very deep into the research of economics.

What you're supposed to be learning in this class are the basic, foundational, fundamental principles of economics.

And that's what I'm going to focus on.

So here's what I'm going to do.

When we talk about these assumptions and conclusions, especially the assumptions, I want you to understand that the assumptions

that we're going to use in this economics class might not be the kinds of assumptions

that would be used in a much higher level economics class.

So if you decide that you're going to someday get a masters or a PhD in economics, you might find out something,

you might learn something in that economics class and think back to this class and say, wow, Professor Ryan was wrong.

What you have to understand is that the assumptions

that we're going to make are important when you're at the beginning stages of learning economics.

So I'm warning you that some of the things that we're going to learn throughout this semester, some of the things that I'm going to teach you, are really only foundational principles.

But when you get to higher levels of economics,

oftentimes we relax or eliminate those foundational concepts and augment them into something much more detailed or much larger or much grander.

So I'm warning you in advance.

This is a principles class.

You are learning the basics of economics, okay?

100

Alright, so, one of the basic assumptions, well, I'm going to give you two basic assumptions in economics.

101

The first one is called the Ceteris, that's C -E -T -E -R -I -S, Paribus.

102

That's P -A -R -I -B -U -S.

103

That's the Ceteris Paribus Assumption.

104

I'm going to put quote marks around it.

105

What does ceteris paribus mean?

106

Ceteris paribus basically means to examine one variable by not changing any of the other variables.

107

You are holding everything else constant so that you can isolate the effects of a single variable on some other phenomenon.

108

Okay, so Ceteris Paribus says that we're isolating all other variables so that we can examine one variable that's changing,

109

because here's what's going to happen in this class is I'm going to say something like, hey, when things are cheaper,

110

people buy more of it.

111

And then you're going to say, well, not always.

112

Sometimes when things are cheaper, people don't want them at all.

113

And I'm going to say, you know what?

114

You're right.

115

Sometimes things are so cheap that people don't want them at all.

116

But I'm using the ceteris paribus assumption.

117

We're going to assume that it's the kind of product that everybody wants.

118

And so now, if it's a product that everybody wants and the price goes down, people are going to buy more of it because they do want it.

119

We're going to assume that it is something that people want.

120

So for example, if the price of garbage goes down, people may say, no, I don't want any more garbage.

121

I'm trying to get rid of my garbage.

122

Well, yes, I agree with you.

123

But if we're talking about something normal, like a cheeseburger, or french fries, or a car, then we can assume,

124

ceteris paribus, that when the price goes down, that people will buy more of it, okay?

125

So that's our first assumption in economics, is the ceteris paribus assumption.

126

The second assumption, what is the second assumption?

127

Oh, the second assumption is rationality, rationality, okay?

128

Now, this is a really, really, we got to be very flexible with this rationality assumption,

129

assumption, but we're still going to use this rationality assumption in this principles class.

130

Here's what the rationality assumption says.

131

The rationality assumption says that people in general are rational decision makers.

132

Meaning, if you give them a choice of whether they can have $20 or $30,

133

that they will choose $30 every single time.

134

And you might say to yourself, oh, there must be some kind of catch.

135

No, I'm telling you, there's no catch.

136

Your choices are $20 or $30.

137

Which one do you want?

138

Everything else is the same.

139

And then, obviously, the rational person is going to say, well, I'd rather have more money than less money, so I'm going to take $30.

140

Yes, exactly.

141

We're going to assume that you are a rational person, that I am a rational person, that I want more good stuff,

142

and I want less bad stuff in my life.

143

That is rationality, okay?

144

So that's the second assumption.

145

And because economics is scientific, we have to start somewhere, and where we're going to start is that we're only going to look at one variable at a time,

146

and then also we're going to assume that people are making rational decisions,

147

that they're not insane, that they are not out to get worse things for themselves, and less better things.

148

No, that doesn't make any sense.

149

We're going to assume that the people, that the individuals, the organizations, and societies that we're dealing with are rational.

150

Okay?

151

All right, now let's move on to conclusions.

152

Oftentimes what we do in economics is after we learn something new or after we understand something,

153

we then draw a conclusion, right?

154

And here's how it goes.

155

For example, let's say that people are spending more of their money on one kind of cereal.

156

People are spending more money on Lucky Charms than they are spending on Cheerios.

157

And so we might draw a conclusion.

158

Well, if people are buying more Lucky Charms than Cheerios and Ceteris Paribus, they both have the same price,

159

then people must like here I'm going to draw a conclusion now.

160

Well, I'm now going to conclude that people prefer Lucky Charms over Cheerios.

161

Now that may not be true in reality, but in my example that is a conclusion.

162

And often times when we draw conclusions in economics there are two kinds of conclusions that we can draw.

163

We can draw or we can come to conclusions that are what we call positive conclusions or normative conclusions.

164

And what we're going to try and focus on in this class is we're going to primarily focus on positive conclusions, not normative conclusions.

165

positive means let's see here what is what is and normative conclusions are what should

166

be what should be we are going to avoid the what

167

should be conclusions now you're going to want to make some

168

normative conclusions as you go through this class you're going to say oh because of that, that means that's terrible, then this is what we should do.

169

So for example, you might say, oh, we might find out economically that there are people in this world who can't have health care.

170

They can't get help when they're sick.

171

And you may think to yourself, oh my goodness.

172

Now, the fact that we conclude that there are people who don't get medical help.

173

That is a positive conclusion.

174

It's just a truth.

175

Nobody would argue.

176

Generally speaking, people do not argue over positive conclusions.

177

And so what I'm going to put over here is, I'm going to say here, no arguments.

178

No arguments over positive economics.

179

Sometimes we call it positive economics and normative economics.

180

So I'm going to put positive econ, and here it's going to be normative econ, okay?

181

So in positive economics, generally, people do not argue over the truth.

182

Everybody agrees that 17 % of the people get no health care at all.

183

Yes.

184

What do your numbers say?

185

17%.

186

What do your numbers say?

187

17%.

188

We all agree there's no argument, but here's where it becomes argumentative, okay?

189

People disagree over what that means we should do.

190

People disagree because of their values, because of their value judgments, okay?

191

So, values, because of their values, people disagree on normative economics about what should be done.

192

And what some people are going to say is, wow, well, those 17 % of people, they should be able to get medical care.

193

And therefore, what we should do is take some money from somewhere and give those people medical care.

194

And some other person, because they have different values, they're going to say, no, that's not what it means at all.

195

That would be very expensive.

196

We can't take money away from those other things to give health care to these people.

197

They're just going to have to deal with not having health care.

198

And this is where people argue is in the normative economics.

199

We will do a little bit of normative economics and you will hear me make statements that are related to normative economics.

200

And I may say some things that you will disagree with.

201

And when you disagree with me, chances are you have different values than I have.

202

And that's okay.

203

You can have different values than me.

204

You should have different values than me you can have very similar values, but generally speaking, every human being has a different set of values.

205

And so we're going to disagree sometimes on what should be done.

206

But positive economics is what is, generally speaking, there are no arguments over that.

207

And here's what I'm telling you.

208

As far as positive economics, one of the things that we're going to learn in positive economics is the fact

209

that when the price of something goes down, people do buy more of it.

210

And we're going to get to that in a much later lesson.

211

Okay?

212

But that's an example of positive economics.

213

All right.

214

So economics is scientific.

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법

쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
