Cupcake economics 2
In the last video we talked a little bit about, at least potentially, starting a cupcake factory.발음듣기
But this is a major investment that I'm thinking about making, so at minimum, I made a spreadsheet here in Excel and it's available at khanacademy.org/ downloads/cupcakes.xls.발음듣기
If you just click slash here, you'll see everything in the download directory, but I'm going to start putting more stuff there.발음듣기
But this is essentially - it'll do all the math for us that we did in the last video, --the investment in the factory.발음듣기
Let's say in the real world, once I actually got bids from contractors and things like that, it ends up costing $1.1 million.발음듣기
Now that I have a computer doing the math for me, I can deal with a little bit funnier numbers.발음듣기
In this scenario, this is the income statement, at least as far as we get to the operating income line.발음듣기
If I change the number of cupcakes, let's see, if instead of a million, I sell five 500,000, it calculates everything accordingly.발음듣기
So it's 50% utilization and then, my return on asset is my operating income divided by my initial investment, right?발음듣기
So in the last one, I touched on a little bit that the real lever that I, as the owner of my cupcake factory, can change is price.발음듣기
And then, obviously, if I charge a lower price more people are going to want to buy my cupcakes and if I charge a higher price, fewer people.발음듣기
Although, there are some things that when you charge a higher price people think it must be better so maybe they want it, or they want to show off to their friends, and look at this expensive cupcake that I eat, and it's kind of a status symbol.발음듣기
And now we can actually figure out under what combinations am I going to make certain amounts of money.발음듣기
So if I charge $1.50 per cupcake and I'm only able to sell 500,000 cupcakes, I'm going to take a loss per year of $275,000.발음듣기
If I sell them for $1.75 and if I sell, I don't know, 700,000 cupcakes, I'm almost at break-even.발음듣기
And, if you're in high school or in middle school, this could actually be a fun - I don't know if they allow this type of thing for science projects.발음듣기
And actually, if you watch the probability videos, I do all those things on [UNINTELLIGIBLE] processes and things like that.발음듣기
You can analyze the business and do Excel spreadsheets and you'll probably end up winning soon. the state science fair.발음듣기
So essentially my operating profit divided by my initial investment, depending on the different prices I might charge and the different quantities.발음듣기
And here it's kind of hard to visualize, so I graphed it as a three dimensional surface. 3D.발음듣기
So as you see here, if I charge $2.80 and I only sell 300,000, then this is my return on asset right here.발음듣기
Everything here is in the negative, right, according to the legend, minus 50% to zero percent return.발음듣기
If I charge $1.60 per cupcake and I only sell 400,000 cupcakes, I'm going to have a negative return.발음듣기
And it actually shows you that it's a fairly interesting and sophisticated thing, that you have these two variables that change.발음듣기
You can only imagine what happens when you start varying the other parameters, but these are the two big ones.발음듣기
And by the way, I've also learned from the cigarette companies and I put nicotine in my cupcake, so I think people will become addicted to it.발음듣기
And a lot of people would be happy with that, but I'm like, hey, I'm leaving money on the table because I'm selling out of my cupcakes.발음듣기
So it makes sense for me to see if there's any - maybe there's some people who want cupcakes, who can't get them because I can't produce that many.발음듣기
There's maybe 50,000 thousand people in the margin who said, hey, you know, I'd buy it at $1.85 but I'm not willing to buy it at $2.발음듣기
Even though I'm selling fewer cupcakes, because I'm charging so much more per cupcake, and I'm making a 37% return.발음듣기
So that's all good and I'm driving a Bentley and I have the biggest house on a hill in town and all of that.발음듣기
This is a better return on investment than the stock market or anything else that I know of.발음듣기
But then Imran - and just if you're curious why I wasn't recording videos for the last two weeks, actually Imran is the name of my son and he came into the world two weeks ago, and so, I think it makes sense to name a cupcake store after him.발음듣기
But let's say he comes in, and he's like, I'm tired of getting an allowance from dad; I also want to produce cupcakes.발음듣기
And he actually has more money because his grandma gave him more money because she likes him more than her son.발음듣기
And so he has $1.5 million to invest because he's like, wow, this is such a good investment, let me put more money into it. $1.5 million.발음듣기
And also, it's a more efficient factory, so it actually uses a little less electricity, and wastes less cream and frosting, and, I guess, nicotine as well.발음듣기
And when he charges $2.90 per - everyone just kind of runs to him, because his cupcakes are just as good.발음듣기
And so, to benefit them - these guys aren't going to go anywhere else --I'm going to raise my prices a little bit.발음듣기
And just when this Imran comes in, and he enters into the space, all of a sudden, what is the return?발음듣기
But his return on asset has gone down to 20 - and, because he's at that utilization, his return on asset has gone down to 20%.발음듣기
When someone is doing really well and getting a really great return, it attracts competition.발음듣기
And if there's enough demand to satiate that new capacity, maybe they will get a better return.발음듣기
But in general, over time, if there's a very favorable return, more and more competition will enter the market.발음듣기
