It is hard to see how the United States can avoid a recession. Unemployment insurance claims have already surged, and this week's numbers look to be in the millions. All indications point to one of the fastest plunges of GDP in US history. Facing this, we may want to turn to previous American recessions to think about our immediate future. But the dynamics of this recession will be different in at least one major way from the recessions of recent memory: services. In most recessions, services are basically acyclical—they just don't move up and down with the booms and busts of the economy. The exception here is the Great Depression (see Figure 1 below), but there the decline in investment is much more severe, as is the upward swing in the recovery. Services, it seems, just don't fall that much—even in the Depression.
