Do falling interest rates raise household wealth-to-income ratios?
Core argument: The authors' quantitative exploration suggests the fall in interest rates from 1989 to 2019 played a prominent role in the observed increase in wealth-to-income ratios.
In this paper, we put forward the notion that the gradual fall in interest rates observed from the late 1980s up until the COVID period likely favored an increase in household-level demand for wealth. Our quantitative exploration suggests that the fall in interest rates from 1989 to 2019 likely played a prominent role in the observed increase in wealth-to-income ratios. The reason we put forward is the need to accumulate more wealth for retirement when interest rates are low - roughly speaking, at the aggregate level target saving motives dominate intertemporal substitution effects.
