How does Modigliani's work relate to consumer spending?
My life-cycle hypothesis is directly relevant to understanding consumer spending. It suggests that current spending is a function of long-term expected income, not just current income. This implies that fiscal policies, such as temporary tax cuts, might have a muted effect on consumption if individuals anticipate that the change is temporary and plan their spending based on their permanent income. This offers a more nuanced view than simpler models.
