Economic profit vs accounting profit발음듣기
대기중
[Background voice] Let's say this past year I started a restaurant and I want to think about what type of a profit I've been making at that restaurant.발음듣기
대기중
We're going to think about it in 2 different ways.발음듣기
대기중
We're going to think about it in terms of an accounting profit, which is really the type of profit that most of us associate with a business or a firm.발음듣기
대기중
We're also going to think about it in terms of economic profit, which we'll see is a little bit different.발음듣기
대기중
Instead of telling us whether a business is producing income, it tells us whether it makes sense to even run the business in the way that we're actually running it.발음듣기
대기중
First, let's focus on the traditional way of calculating profit.발음듣기
대기중
Let's say my firm, my restaurant, (my firm in a restaurant) in year 1 it brings in, in revenue, it brings in $500,000.발음듣기
대기중
Revenue literally is the amount of money the customers pay me to eat at the restaurant.발음듣기
대기중
They are paying for their dinners.발음듣기
대기중
This is literally the money that's coming in the door.발음듣기
대기중
Sometimes people call it the top line, because it's literally the top line of our income statement.발음듣기
대기중
It's the top line.발음듣기
대기중
Now we have to think about our expenses. Expenses.발음듣기
대기중
Now, when you're running a restaurant one of the obvious expenses is going to be the cost of food.발음듣기
대기중
Food, we're going to say cost us $100,000. $100,000.발음듣기
대기중
Then, you have the cost of labor.발음듣기
대기중
I have the wait staff.발음듣기
대기중
I have the chefs and the bus boy.발음듣기
대기중
On all of those people, in this past year, I spent $100,000.발음듣기
대기중
Then, I have, and I am going to assume that I don't own the building, that I rent the building.발음듣기
대기중
So, building rent.발음듣기
대기중
I'm assuming this is on the building, let's say that that was $200,000.발음듣기
대기중
Then finally, I really just rented everything.발음듣기
대기중
I also rented the equipment, all of the stoves, the fridges, all of that stuff.발음듣기
대기중
None of this is stuff that I own, so the equipment rent.발음듣기
대기중
Equipment rent, I spent another $50,000.발음듣기
대기중
How much profit do I have here?발음듣기
대기중
Those are all of my expenses.발음듣기
대기중
I didn't borrow any money, so I didn't have any interest expense or anything like that.발음듣기
대기중
How much profit do I have before paying tax, or essentially my pretax profit?발음듣기
대기중
The reason why we think of it in those terms is because the amount you pay in tax is usually derived from your pretax profit.발음듣기
대기중
That depends on where this business is, what country, what state, what type of business it is.발음듣기
대기중
The easy way to calculate pretax profit, pretax profit.발음듣기
대기중
This is pretax and we're thinking in terms of accounting profit right over here.발음듣기
대기중
We take how much money comes through the door and then we just have to subtract out all of the payments we essentially have to make to other people.발음듣기
대기중
What we have left is out pretax profit.발음듣기
대기중
500,000 minus 450,000 gives us a pretax profit (I'll do it in that same bright yellow) of $50,000.발음듣기
대기중
I'm assuming that I'm the only owner of this business, so I can essentially take it all out for myself.발음듣기
대기중
Maybe help pay my own personal rent or whatever else, or I could take some of this or all of this and reinvest it back into the business.발음듣기
대기중
Maybe I start buying my equipment or I expand in some way.발음듣기
대기중
Who knows what I might do with that money.발음듣기
대기중
This is just traditional accounting profit.발음듣기
대기중
This is how profit is calculated.발음듣기
대기중
Although, this is a super simple example.발음듣기
대기중
In the future I would like to do more nuanced examples in the accounting world.발음듣기
대기중
This, you would refer to as just accounting profit. Accounting profit.발음듣기
대기중
When people in the everyday world talk about profit, this is normally what they're talking about.발음듣기
대기중
Now, when economist talk about profit, they're talking about something slightly different.발음듣기
대기중
The best way to realize that is to just calculate economic profit for this exact same business, or this firm, as a economist would call it.발음듣기
대기중
A firm really is a general idea for an organization that is trying to maximize profit.발음듣기
대기중
Once again, it's year 1.발음듣기
대기중
Actually let me just copy and paste it.발음듣기
대기중
It's year 1, that's our revenue.발음듣기
대기중
I'm going to copy and I'm going to paste it.발음듣기
대기중
This right over here.발음듣기
대기중
Looks pretty similar.발음듣기
대기중
Now, we're going to think about things in a slightly different way.발음듣기
대기중
Economist view cost in terms of opportunity cost.발음듣기
대기중
As we'll see, some of the opportunity cost you can measure in terms of dollars.발음듣기
대기중
Some are less explicit.발음듣기
대기중
I'm going to write here, just so we can get in the economist frame of mind, opportunity cost.발음듣기
대기중
Within opportunity cost there are going to be explicit opportunity cost and implicit opportunity cost.발음듣기
대기중
First, let's do the explicit.발음듣기
대기중
Explicit opportunity cost.발음듣기
대기중
Actually, all of these are explicit opportunity cost.발음듣기
대기중
Let me just copy and paste that.발음듣기
대기중
I will copy and paste.발음듣기
대기중
All of these are explicit opportunity cost.발음듣기
대기중
The reason why they are explicit is I'm actually making up ...발음듣기
대기중
I'm paying money for all of these things.발음듣기
대기중
Even the equipment and the rent of the apartment, I don't own it.발음듣기
대기중
I'm actually paying whoever does own it.발음듣기
대기중
These are direct outlays out of the business.발음듣기
대기중
I'm explicitly making these payments.발음듣기
대기중
The reason why we can think of them as opportunity cost, even though they're given in dollar terms, is that if I was spending $100,000 on food, that's $100,000 that I couldn't spend on something else.발음듣기
대기중
If I'm spending $100,000 on labor, that's $100,000 that I couldn't spend on something else.발음듣기
대기중
I'm just measuring the opportunity cost in terms of dollars, but dollars that I could have spent on other things.발음듣기
대기중
So far, it looks pretty much identical.발음듣기
대기중
I'm just viewing it with a slightly different lens.발음듣기
대기중
You're like, "Well, what's the big deal here?"발음듣기
대기중
We're going to see a little bit of divergence when we start thinking about the implicit cost that really weren't taken into account here, the implicit opportunity cost especially. Implicit cost.발음듣기
대기중
If I am running this business and let's say, in order to run it I actually had to focus on it full time.발음듣기
대기중
I couldn't have actually quit my job.발음듣기
대기중
Then, there's an implicit cost of …발음듣기
대기중
An implicit opportunity cost of the job that I gave up, or my wages foregone.발음듣기
대기중
Let me write this down, wages foregone.발음듣기
대기중
Let's say, and this will depend on who we're talking about.발음듣기
대기중
Let's say I was a doctor and I was making a nice steady, risk free $150,000 a year.발음듣기
대기중
I was giving up $150,000 a year.발음듣기
대기중
Now, we've listed all of the explicit and the implicit opportunity cost.발음듣기
대기중
Now we're ready to calculate our economic profit.발음듣기
대기중
Let me draw a line over here.발음듣기
대기중
Our economic profit is going to be our revenue that we're taking in, minus all of these expenses.발음듣기
대기중
That gives us a positive $50,000.발음듣기
대기중
Now, we have to subtract the wages foregone.발음듣기
대기중
Then, I get to negative $150,000.발음듣기
대기중
This is interesting.발음듣기
대기중
This is kind of a big discrepancy here.발음듣기
대기중
In accounting terms, I'm profitable.발음듣기
대기중
In economic terms, I'm not profitable.발음듣기
대기중
The important thing to realize is economic profit, when it's negative, isn't saying, or you say that you have $100,000 economic loss, or an economic profit of negative $100,000.발음듣기
대기중
This isn't saying that the business or the firm isn't spinning out money.발음듣기
대기중
What it is saying, is it probably doesn't make sense to run this business or at least to run this business in this way.발음듣기
대기중
If this was 0, that means, hey, it's probably making money, but you're kind of neutral whether it makes sense to run it this way or not.발음듣기
대기중
If it's positive, that means it definitely does make sense to run the firm in this way and that it is definitely doing better than all of the alternatives.발음듣기
대기중
This right over here is saying, look, you're making $50,000 a year, that's the 50,000 that you have to spend, if you're the owner, or reinvest in the firm.발음듣기
대기중
This is saying, essentially, look, you could have been making more money than that $150,000.발음듣기
대기중
Instead of making $50,000 doing this, you could have been making $100,000 more doing something else.발음듣기
대기중
You are essentially giving up, you are giving up $100,000 to do this restaurant.발음듣기
대기중
If you are a rational decision maker and you're really are about maximizing your profit, this actually might not make so much sense for you.발음듣기
