Durables consumption has experienced extreme volatility over the last 9 months (since the election). However, services and nondurables should follow the permanent income hypothesis — at least halfway (DSGE’s usually incorporate about 50% hand-to-mouth consumers). So what do we see?

The gap between services consumption and trend is even larger. To the extent that services consumption is driven by the permanent income hypothesis (even if up to half of consumers are hand-to-mouth), this means there’s been downshift in perceived future stream of income.
