Elasticity of demand is equal to the percentage change of quantity demanded divided by percentage change in price. In this video, we go over specific terminology and notation, including how to use the midpoint formula. We apply elasticity of demand to the war on drugs, and more broadly to the prohibition of a good when it has an elastic demand.

Very helpful for someone taking a college level online economics class and I have to teach myself everything, now it makes sense. Edit: Idk why I’m getting responses on this comment so many yrs after making it. I don’t even remember the class I took. It was probably in my freshman yr of university. It was helpful at the time that’s it. It was required of my degree to take economics as a business major. And yes you can probs take this in high school in AP or something idk nor do I care. Like yeah in college you have to take stuff you probably could’ve gotten credit for in high school. I got college credit on history and English classes not science or math. Some classes you can’t get AP credit for. Anyways yeah that’s all I have to say.

The curve of corn is inelastic and in case of inelastic demand curve the revenue rises with the increase in price. In the given year, there will be a shortage of supply which will increase the price and shift the supply curve up and left. So, as the price is increased the revenue of farmers will increase.

I'm getting my Masters from a top tier (USNWR top 3 in this area) university. The professors here are fantastic and my microeconomics professor is one of my favorites. They are not as effective as these guys. Your knack for avoiding jargon, the build of the curriculum is excellent with no surprises so far, the avoidance of comprehension-killing abbreviations, and the tie-in to real world scenarios is simply outstanding. I am in my late 50s, a physician scientist and have sat through tens of thousands of lectures. You 2 are among the GOATs. I mean it. Gentlemen, you have created a phenomenal legacy and should be VERY PROUD!. Thank you all. Do you have a biostatistics channel?? LOL

@selvinmacwan2689

when yield in going down the supply will be less and the price will go up. thus when the price goes up and the demand goes down by just a little we get more revenues and a inelastic curve. Also the reason why the demand will go down just by a little is because the substitute of corn that is soybeans is also not more in supply.
@tadej3080
@tadej3080 3 года назад
I'm also guessing because corn is a broadly defined good, which is used in many different ways, the price elasticity of demand will be lower enough just as it is.

@MusicalInquisit
@MusicalInquisit 5 лет назад
Since the yield must have decreased, the amount supplied must have decreased in the market. Therefore, the supply curve shifted to the left. As a result, the equilibrium quantity is of a lower amount than the previous quantity demanded. If the demand curve remained the same, then it would be fair to say that the price has increased as a result of the shift in supply. However, if the total revenue increases for farmers because of the increase in price, it would be safe to say that the demand curve was inelastic, at least in the short-term.

Slope of the demand curve gives clue of the elasticity type. Curve ( or slope ) formula is rise= P / run = Q. A steep one will be inelastic as price (p) rise more than demand (Q) decrease. (or vica versa)

hi, i have a question. if the price elasticity of demand is -1.4 which is negative. is it considered to be inelastic because its less than one, or is it elastic because we don't consider the negative and we only take the number so its going to be greater than one. thank you
