- Should Stores Charge Different Prices for Different Size Clothes?
This was a stupid little post on the theory behind differential pricing of clothes that I never expected anyone to read. I have no early idea why it is my most-viewed post ever.
- Piketty and immiseration of the capitalists
This is a post I wrote to provide some context for Piketty's famous book, Capital. The model I discuss in the post is taken from a line of optimal tax theory research that Piketty contributed to, and I think the model helps clarify why Piketty thinks about capital and inequality the way he does (and why you should too!).
- Economic mobility is irrelevant
As it's title says, a short critique of "economic mobility"--they way "mobility" is typically defined, it is possible to have both rising mobility and immiseration happening at the same time to the same individuals.
- In-Home HIV Testing with OraQuick
To show solidarity with the HIV+ community, I tried a new in-home testing kit and blogged about the experience. I was rather disappointed with Oraquick's low sensitivity: 8 out of 96 HIV+ individuals actually tested negative in the clinical trial cited in the accompanying literature. While it would cost $10 to $20 more to get tested in a doctor's office, the higher accuracy is certainly worth it.
- Ladies and gentlemen, the taper has arrived
Ok, actually this is the post in my top ten list, but I wanted to send you to the revised version of the Taylor rule app, which has some stylistic and performance improvements over the old app.
- Be careful how you wield Chamley-Judd
A post making what ought to be an obvious point: the famous Chamely-Judd theorem stating that optimal capital taxes are eventually zero is actually something of a knife-edge result that ignores potential off-budget redistributionary effects of taxation.
- Obamacare and Singapore: a comparison
A comparison of Obamacare to the Singapore health system, which has been lauded by many US conservatives as a better alternative to Obamacare. I show that the two systems are actually pretty similar, and Obamacare is, if anything, more conservative. This post appears to be much more popular in Singapore than in the US.
- Unbundling: Why Matt Yglesias is wrong
Matt Yglesias was wrong once, on the internet.
- Making an unbreakable code doesn't seem that hard.
This was another stupid post I didn't expect anyone to read. Just some random thoughts on how to make an unbreakable code.
- Why bets aren't a good measure of beliefs
All good policy forecasts turn out to be wrong. The reason why will surprise you.
As always happens, a few of my favorite posts didn't make top ten, so here's a few honorable mentions:
- Moral hazard is good.
Don't listen to the freaks--subsidizing healthcare for sick people really is welfare-improving, socially optimal policy.
- Why do statisticians use standard deviation?
This funky metric isn't just mathematically practical, but has some deep theoretical roots.
- Here's what Harold Pollack's been tweeting about
Health insurance is a Markov process. Harold Pollack get's it.
