This time last year, we were debating the shape of the recovery in alphabetic terms. Choices were the L, where the economy fell and stayed down for a long while, and the U, where the fall was followed by a period on the floor before a rise. Some offered the W, a series of rises and falls as pandemic waves took over, and the K, a widespread drop followed by strong rises and falls across sectors and economies. Are a tick or a swoosh better analogies?
