Every time I start to write about the economy, I worry that I might drill down too deep, because most people don’t care as much about the details of the economy as they care about how much money is in their bank accounts and wallets. I get that, but I think it is important to offer some thoughts on the internals of the economy that may or may not be known to most. As I used to teach my students, it is the interconnectivity of things that really give us the best picture of what is really going on in the economy. Unfortunately, most of the talking heads on TV are quick to speak in jargon, spout numbers that are hedged by probabilities and predict economic performance without context.
