Small-Scale Question Sunday for April 7, 2024

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

Thanks for realizing this. In general, people don't know enough economics.

When I took a class on microeconomics, which was one of my favorite classes, we covered, among other things, the following. I think these are worth knowing:

  • supply and demand (and graphs thereof)
  • opportunity cost
  • a good sense of just how much economic growth we've had, and the ways that has improved our lives
  • A robust sense of how the price system reflects the availability of goods and acts as a signalling mechanism for when resource usage is economically productive and incentivises innovation and entrepreneurship
  • Why "price gouging" can be good, actually. (Very brief answer: we operate in a world of scarcity, and when prices reflect that accurately, resources can be allocated more to those who need them, and incentivize mitigating that scarcity)
  • the effects of price controls, or cost-imposing regulation, including how minimum wage could reduce employment, or how rent control is "the most efficient technique presently known to destroy a city—except for bombing"
  • deadweight loss (in taxation of goods, subsidies, and in monopolies, among other things)
  • how competition will force long-term-risk-and-opportunity-cost-adjusted profits to zero (in a sufficiently abstracted case: in practice, a bunch of things allow some, but not too much, profit to continue to be made, like economies of scale)
  • monopolies and cartels, why these are inefficient, why these are still better than the monopolists in question not existing, why cartels are better than monopolies
  • Pigouvian taxation
  • Coase theorem (keeping in mind also when it doesn't apply)

Public choice economics, and how incentives cause governments to fail, and how we often can't just trust them to solve any problems markets lead to. Some, among other government failures that happen are:

  • in general, politicians' incentives are not necessarily to produce whatever the optimal set of policies may be for the people
  • interest groups that would benefit policies that produce concentrated benefits to them, but impose diffuse costs on most others often can get those policies passed when it's inefficient
  • money spent on lobbying is wasteful: they'll spend up to the benefit of the good, increasing the cost to society
  • regulatory capture, and lobbying and weaponization of laws against competition

Also, read Bastiat's candlemaker's petition; it's hilarious.

I'm sure there's also macroeconomic things worth learning, but I, unfortunately, haven't really learned macroeconomics.

(Though I did watch one video from marginal revolution on the Solow model, which was definitely a useful concept)

It's probably also worth being aware of the whole situation with the US debt, and worth having a sense of some of the consequences of when we actually basically run out of money.

And that the ultra-wealthy usually have their wealth in the form of ownership of companies (and is exaggerated, as prices would fall as their stock sold), not giant vaults of cash.

The class I had used Gwartney et al's "public and private choice" as our textbook, so I assume that would be good, though it's possible that you might not want to spend money, and I don't know what the most efficient way to learn is.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
