Economic Cycles
A slowdown is not a recession, and quarterly headlines rarely reveal which phase the economy is in. Investment, inventories, final demand and productivity drive the cycle more than reported GDP, which arrives late and gets revised. The Sahm rule, jobless claims, recession-detection composites and every US recession since 1948 are gathered here to date a phase before the national accounts catch up.
