I often think of the economy as a metaphorical set of pipes with money (the "water") flowing through them. Recessions typically happen when the pipes "clog," causing the water to flow well below its normal pressure. Governments have to respond, taking actions to "unclog" those pipes to get the "water" flowing again.

But the recession I believe we've already entered is very different in kind, not just degree. The coronavirus pandemic has forced large sectors of our economy to close down, severely restricting consumption and economic activity. This time, the "pump" has broken. It may not matter how much anyone tries to unclog the pipes, as little will flow until the pump starts working again.

This metaphor has some significant ramifications for what we'll experience over the next few months (yes, months, not weeks). It feels like we will have a two-stage recession:

One other big difference with past recessions is the pace of the buildup. Past recessions tended to build up over time whereas this one came on us almost suddenly. The just-announced unemployment application numbers for last week prove this point. We went from “normal” rates one week to 3.28 million last week. By way of perspective, that is almost 5 times the record for any week (695K way back in 1982). There were roughly 155 million people employed in 2018, so 3.28 million unemployed is roughly 2% of the entire workforce being laid off in a single week.
