Proponents of fiscal stimulus argue that government spending is needed to replace the private spending normally lost during a recession. Estimates of the so-called fiscal multiplier based on wartime episodes are used to support the proposition that a peacetime intervention can "stimulate" the economy in a desirable manner. The author argues that a wartime crisis is fundamentally different from a peacetime economic crisis.
The increasingly rapid productivity growth that began in the 1990s was the defining economic event of the decade and a major topic of debate among Federal Reserve policymakers. A key aspect of the debate was the contrast between information contained in aggregate data, which initially suggested little productivity gain, and anecdotal firm-level evidence, which hinted at the productivity acceleration.
