Elasticity of Demand
How much does quantity demanded change when price changes? By a lot or by a little? Elasticity can help us understand this question. This video covers determinants of elasticity such as availability of substitutes, time horizon, classification of goods, nature of goods (is it a necessity or a luxury?), and the size of the purchase relative to the consumer’s budget.

This channel is highly underrated! The concepts are taught in such a simple and lucid manner. Absolutely brilliant 👏
I enjoy and understand these lectures more than my microecon class. Thanks for the help.
Dear Alex, the fact that you are an Iranian not only makes me more thankful but proud too. love and respect from Iran

I have Wasted Coaching Fees Rs. 40,000. But I don't have Understand anything from my Tuition but this Channel helps me a lot. It is much better than any Courses or Tuition etc.
wow. interesting and SOOO much better than whatever my microeconomics was trying to explain in a 2 hour lecture. this was clear and to the point. thank you so much!
Thank you so much! Your explanation and examples make it so easy to understand the concept of Elasticity. I was reading the textbook and it didn't make sense, but watching this video clarifies the concept of elasticity.
This is so goood! I was reading my textbook and had no idea what was going on. Look at your video and I get it; I feel as if I don't need to memorize as I get it. Thank you so much!
so good! I'm studying for my mid term. I didn't understand a bit from my professor. So grateful... Thank you.
Another great video! 11:53 "Consumers probably won't even notice whether toothpicks are 50 cents or a dollar. That's a 50% increase in price..." :O

Well it's a 50% increase if you think that 50 cents are 50% of a dollar, instead of viewing this as 1 dollar is a 100% increase of 50 cent. But that's just the way they you look at it.
This video has helped me so much with my project so glad I found this
Thank you for a great lesson, this can not only work in real life, but also in a game like Runescape that have its own marketplace, like food supply and weapons were food is elastic and weapons are less elastic.
thanks for you supports young economists and also i thank for your effort that paid the economics...
I really like your videos. They have helped me alot. However, changing the price in toothpicks from fifty cents to a dollar is a 100% increase. 50% increase would be seventy-five cents.

Thank you for the help.
Thank you!!!
great video again wow!
Thank you ❤
awesome guy very helpfull
On the elastic demand curve , the quantity demanded is more responsive to the price than it is on the the inelastic demand curve
Please explain total outlay method and ARC elasticity of demand
Thank you
awesome!!!
Thank you so much love you ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
Thank you.
thanks alot
very thanks
It's one of those foundational concepts
thanks sir.. I have a question that my teacher asked me.. the question is that "why price is on y axis and quantity of demand is on x axis"??

+Shiv Shanker You should review some of the videos from earlier in the course. We begin by covering the demand and supply curves, and equilibrium price. These should help with your homework. Good luck! - Meg (Link: kzread.info/dash/bejne/aZmOxbKsad2ff6Q.html&nohtml5=False)

The narrower the classification the fewer substitutes and the more elastic the curve
thank uuu

$0.50 to $1.00 for the price of toothpicks is a 100% increase in price, not 50%. Just to illustrate that it's an even larger price increase than you stated, and still it isn't considered a big deal.

The quantity is changing a lot in response the price

Toothpicks increase in price from 0.5 to 1 is a 100% increase in price isn't it?
@schanemassey3861

yes but its a relatively small increase to a consumer, thus the quantity demanded will not change.

There would be more Sprawl if the price is low
It's honestly infuriating that the x axis (input) is quantity sold and the y axis (output) is price. Who the F did that bit of ass-backward reasoning? I have to reverse all of my intuitions about how to use the supply and demand curves. You guys even say "price causes a change in quantity demanded" because that's absolutely the common sense way to think about it. You have direct control over the price and only indirect control over the quantity demanded via the price. But my brain is wired from a decade of math class to look to the x axis for the input (which would be PRICE) and the y axis for output (which is QUANTITY).

I would bargain when the purchase is a large fraction of the budget
