The Most Interesting Law Of Demand?

Guess who learned how to use a meme generator and knows that demand curves slope downwards…

Actually, that one was from the Cengage Learning Facebook page, but I’m apparently one to take an idea and run with it (or beat a dead horse, depending on your perspective). We all know that there are plenty of determinants of demand other than price, so I made a few more graphics.

Income is an important determinant of demand, and we can have normal goods

…or inferior goods:

Prices of related goods are also relevant factors for demand, and we can think about substitutes

…and complements:

In fairness, tastes and expectations are also determinants of demand, but I couldn’t decide what the Most Interesting Man in the World would have to say on those topics.

I’m also trying to picture him saying ceteris paribus here, since technically he should be giving the “all else being equal” caveat…but I still can’t decide how ceteris paribus should be pronounced, so my visualization is a bit of a non-starter.

If you prefer, you can review the determinants of demand in video form:

    This could be a good hashtag.

    Presumably, The Most Interesting Man in the World is wealthy enough that he is insensitive to the price beer.

    Speaking of wealthy people, can we have a meme for Mitt Romney as The Least Interesting Man in the World? His tagline could be, “I don’t always drink beer… But when I do, I drink non-alcoholic.”

    That’s ok, most economists omit “ceteris paribus” from their thinking anyways.

    I would substitue “pizza” for “wings” in the last one. Maybe I’m just old school.

    I bought some Dos Equis for the first time last year. It was on sale for the week of cinco de mayo (bigger here in LA than Boston I believe).

    As I was drinking it a thought occurred to me, “I don’t always drink Dos Equis, but when I do it is because it is on sale”. Kind of *begs* [sic] to be said, doesn’t it?

    I was also unimpressed by the taste. Pretty much any craft beer that I’ve had I liked better. Your mileage may vary….

    I’m doing exatly this topic at the undergraduate level right now ( I’m taking a class in microeconomics.) Maybe someone could they could create a captioned picture that relates to the Income Elasticity of Demand. ‘When they drop the price of beer by a small amount, I buy a lot more of it,’ or something like that.

  • 12 Comrade V // Mar 24, 2012 at 9:13 am

    Whoops, meant *Price Elasticity* instead of income elasticity.

  • 13 happyjuggler0 // Mar 24, 2012 at 2:24 pm

    Comdrade V,

    Doesn’t the first pic do that? Or do you have something less concise in mind?

    I just didn’t look closely enough ‘happyjuggler0’ It’s a bit embarrassing actually…
