Teaching economics & ethics with Kitty Powers’ Matchmaker

Unusual ways to teach economics. I’m currently playing Kitty Powers’ Matchmaker, a silly but fun little game in which you run a dating agency and try to get your clients on successful dates and, eventually, into a successful relationship.

Now one way of playing this would be to just prioritize the benefit of each client, trying to get them in maximally satisfying relationships as fast as possible. But while I sometimes do that, often I do things differently.

In one case, I had a client who’d been on two bad dates already, and was threatening to march out and give my company a bad reputation if she’d have one more bad date. I didn’t have any good matches lined up for her. I could have just kicked her out, but that wouldn’t have given my company any money. So instead I put her on a date with someone who seemed incompatible, but just had her lie about all the incompatibilities and say what the other person wanted to hear. That way, they’d end up together, and I’d get my money and be rid of the troublesome client. Of course I knew that they’d break up later and that would hurt my reputation a bit, but I figured that it would still be better for the company than kicking her out now.

(In my defense, I have only done this once, and I felt kinda bad about it.)

This situation is known in economics as the principal-agent problem: a situation where someone (the “principal”) hires someone else (the “agent”) to do something on the principal’s behalf, but the self-interests of the principal and the agent differ. So for example, you may try to get a real estate agent to sell your house and give them a cut of the profit. It would be in your interest if the agent sold it for as high a price as possible, but the agent may actually benefit more if they spend less time on each individual sale and instead sell a lot of houses more cheaply, but in a shorter time. This was confirmed in a study in which it was found that real estate agents tended to sell other people’s houses considerably faster and cheaper than they sold their own houses.

Or, you might go to a matchmaking agency to get into the relationship of your dreams, but your matchmaker also has an interest in getting your money and benefiting the company.

Here’s another thing that I do in the game that some might consider questionable. When a client comes in, they will tell me their personality traits, e.g. introvert vs. extrovert. It’s best to pair them off with someone who has the same personality traits. But when the game shows me a list of people I can try to match my client with, by default I don’t know the personality traits of those people. Instead, I have to have some client date those people and discover their personality traits, and then I too will learn them.

Now suppose that a new client comes in, and I know of someone I could have them date who’d be perfectly compatible. I also have a bunch of other possibilities, whose personality traits I don’t know. Do I send my client on the best possible date right away? Of course not! Instead, I’ll send them on a few dates with the unknowns, so that I can discover the personality traits of the unknowns, and only after a few bad dates will I pair my client with the best match. This way, I’ll know the personality traits of as many people as possible, and will always be able to know of a compatible match for my next client.

Is this ethical? You could argue either way. Yes: I’m still sending my client to a good relationship eventually, and although it might give my client a few bad dates in the beginning, that helps other clients eventually get a good date. No: I have an obligation to prioritize the interest of my current client at all times, and it’s not in their interest to have a bad time. The first argument has a bit of a consequentialist vibe, and the second one has a bit of a deontologist vibe. If you were teaching an introductory ethics course and wanted to give your students a different example than the usual ones, maybe you could have them play the game and then ask them this question.
