Real risk-free interest rates have trended down over the past 30 years. Puzzlingly in light of this decline, (1) the return on private capital has remained stable or even increased, creating an increasing wedge between public and private rates of return; (2) stock market valuation ratios have increased only moderately; (3) investment has been lackluster. We use a simple extension of the neoclassical growth model as an accounting framework to diagnose the nexus of forces that jointly accounts for these developments. We find that rising market power, rising unmeasured intangibles, and rising risk premia, play a crucial role, over and above the traditional culprits of increasing savings supply and technological growth slowdown.
