文章摘要： We develop a heterogeneous agent, overlapping generations model with non-homothetic preferences that nests several explanations for the decline in the natural rate of interest (Rn) suggested in the literature: demographic change, a slowdown in productivity growth, a rise in income inequality, and public policy. We add out-of-pocket health expenditures to the analysis. The model can account for a 2.2 percentage point (pp) decline in Rn between 1975 and 2015, within the range of empirical estimates. Rising income inequality is an important driver (-0.70 pp), and together with demographic change (-0.71 pp) and the slowdown in productivity growth (-1.0 pp) explains most of the decline. Growing public debt is the major counteracting force (+0.31 pp). Permanent income inequality is of greater importance than inequality due to uninsurable income risk, and matching the degree of non-homotheticity in consumption and savings behavior to empirical estimates is essential for this result. We find a moderate role for out-of-pocket health expenditures (-0.14 pp). We predict that Rn reaches a low of 0.38% by 2030, after which a slow reversal begins. The natural rate stabilizes at 1% over the long run, a low level when compared to the postwar path of Rn implied by the model. This remains true even if we take into account soaring public debt levels due to the COVID-19 pandemic. Fiscal policy can have considerable impact on the level of Rn, and we propose to treat the level of the natural rate as a public policy choice.
