On my way to several appointments, so I’ll pass on this piece by Noah Smith without further commentary: Markets in almost nothing. Interesting to watch Noah evolve towards some points of view I’ve held/been developing over the years, though I hesitate to crow too much as I can’t step to his level in terms of explaining, debating, and defining things within economics. I have just enough* economics knowledge to be dangerous. See my comment there as well for some ideas, quotes, and related pieces.
*(or possibly too much, or even not enough…?)
