The Five YO Trilemma

Explain, Samrudha says, the difference between perfect competition and monopoly to a five year old. Not, mind you, an ELI5. To a five year old.

And not just any old explanation, he goes on to add. Explain it as a joke. Again, to a five year old.

And having decided that this is not enough (Samrudha takes his local non-satiation very seriously), this has to be done within the length of a tweet.

So: explain the difference between two economic concepts to a five year old, in humorous fashion, and within the length of a tweet.

This is what those general purpose transformers were invented for, no? Summon forth a knight of the large language realm, and command it to oblige us!

And verily it was summoned, and verily it laid an egg:


So can we leave CRISPR editors, protein folding and spreadsheets-on-steroids to those knights of the l.l.r, and have them leave Samrudha’s trilemmas for us?

I volunteer to step up for team human, if volunteer is the word I’m looking for:

Here are the rules of engagement:

  1. I will not ask Claude/ChatGPT/Gemini to help me draft my tweet length microecon theory joke for a five year old.
  2. I can refer to Google/textbooks if I wish to for academic references, and to source and modify jokes (but this is optional, not mandatory)
  3. My explanation cannot be more than 280 characters in length (and thank god the world has doubled in quality since Peter registered his complaint)
  4. The tweet should be accurate from the point of view of theory and it should elicit a response that lies somewhere on the Groan-Chuckle-LaughUproariously scale.
  5. I can ask C/C/G to evaluate my work of art

If you wish to step up and do battle, please be my guest. But these rules listed here are sacrosanct, mind you!


With that being said, here’s my thought process:

  1. I want to emphasize (to the five year old) the fact that there are “goods” out there that are very similar to each other in terms of quality, and that they “cost” the same.
  2. One ought to be indifferent about who one “buys” this good from among the many sellers offering it.
  3. So in effect, many sellers | same price | homogenous good are the three features of perfect competition I am choosing to focus on.
  4. I also want to emphasize that the five year old can choose to “spend” their “endowment” somewhere else too.
  5. This somewhere else must be a good that is different in the eyes of the five-year old, in terms of quality. It must be available from a single seller, and at a higher price than the perfectly competitive “goods”.
  6. And of course, this point must be made as a joke that is comprehensible to a five year old, and both the point and the humor must be appreciated.
  7. And, of course, in 280 characters.

Why are “goods”, “cost”, “buys”, “spend” and “endowment” in inverted quotes? Because these concepts (and others too – price, for example) matter, but must be used/explained in such a way that a five year old “gets” them.

Since money is a difficult concept to explain to a five year old, what is scarce in a five year old’s life? I’m a parent to a ten year old, and I can confirm that some things haven’t changed since the 1990’s:

So let’s say the five year old has fifteen minutes to “spend” before bedtime, and she can “buy” whatever video she wants to watch. Whatever she watches by definition implies that she can watch nothing else, and let’s assume that only whole units can be consumed – she can’t start to watch a video and discard it as boring twenty seconds into it.

(Not a realistic assumption? You don’t say. But cut me some slack here, dammit!)

So should she watch three random ChuChu TV videos, or a Peppa Pig episode?

What, you ask, is ChuChu TV? And, you ask, what is Peppa Pig?

Jon Snow knows more than you do.


There’s no end to ChuChu TV videos (trust me, I know), and there’s no end to clones of ChuChu TV videos (again, trust me). They all look the same, sound the same, and for all I know and care, are the same.

And while you’d be right to say that there’s no end to Peppa Pig videos either, there’s no clones of Peppa Pig videos. I mean, folks may have attempted cheap knock-offs, but as with the iPhone so with Peppa Pig. If you don’t have it, well, you don’t have it (and yes, once again, trust me. I know).


And so here’s my tweet length joke, understandable where a five year old is concerned, that explains the difference between perfect competition and monopoly:

You have only fifteen minutes until you go to bed. Do you want to watch three ChuChu TV videos, or one Peppa Pig episode?


Not bad, you might say. But how’s this funny?

As I was saying, Mr. Not-Even-Snow.

Every single parent (and kid) reading that bit got it.

You have only fifteen minutes, it seems.

Hahahahahahaha.

Breakthroughs of 2023

I’m amazed and delighted by how little I know about almost all of them, and how helpful ChatGPT is with each tweet. And “new ancient language” is my favorite phrase of the lot!

Twitter Stories

Back in the day, when I had structure, regularity and a schedule here on EFE, Saturday used to be about five tweets that I enjoyed reading that week.

Which, on reflection (and some gentle prodding from Navin Kabra) wasn’t the brightest idea, because that’s what likes and RT’s are for on Twitter. So how about maybe a brief write-up based on a tweet that I read recently?

This week’s tweet that turns into a post is based on a variety of things. First, Nassim Nicholas Taleb.

The Black Swan is kind of like Thinking Fast and Slow, in the sense that everybody claims to have read it, and very few people actually have. If you haven’t read all of his books, please get started. The order doesn’t really matter, but if you’re asking, my favorite is Anti-Fragile.

There’s a lot to like about his books, his tweets and his outlook towards life, and this tweet is one example (note that I am talking about the pics in the reply, not the original tweet):

Now, the original tweet, reposted as a stand-alone:

So what is the company about?

Nasser Jaber is cofounder of the Migrant Kitchen, a catering company and social impact organization that hires immigrants, migrants, and undocumented workers to both train them in commercial cooking as well as help gain their cuisines more exposure in the marketplace.

Read the whole article! I got to learn about quipe (kibbeh, apparently), and esfiha (the spelling differs based on context, so my apologies if I got it “wrong”), among other things.

Twitter is a wonderful, wonderful way to learn more about the world, but it is like a garden, in the sense that constant weeding is required. But when you tend to it just so, it is completely worth the effort!

If you have had moments of serendipity on Twitter that you’d like to share, please, send them along. @ashish2727 on Twitter.

Thanks, and enjoy the weekend 🙂
