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.

    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.

    $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.

    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).
