Does rising debt depress future demand and natural interest rates?
Core argument: The "indebted demand" framework argues that rising debt transfers income from borrowers to savers, and because savers have higher saving rates, aggregate demand falls as debt service payments rise and borrowers cut spending.
The concept of "indebted demand" highlights how rising debt levels transfer income from borrowers to savers, thereby depressing aggregate demand. As debt service payments increase, borrowers reduce spending, while savers, with higher saving rates, do not fully compensate for this reduction. This dynamic is exacerbated by secular trends like income inequality and financial liberalization, which elevate debt levels and lower natural interest rates. Consequently, economies face a "budget constraint for aggregate demand," where debt-financed stimulus can initially boost demand but ultimately reduces future demand and natural interest rates. This creates a debt-driven liquidity trap, limiting the effectiveness of monetary and fiscal policies and necessitating redistributive measures to mitigate recessionary impacts.






Ed Comment:“Of course we know the truth from studies of identical twins separated at birth. 50 to 80% is genetic (probably more if you did a regression using all the relevant determinants of success) and only half of the rest is shared environments, at least as the shared environment is currently administered. That means the shared environment could be as little as 10%, where a 20% improvement only yields a 2% gain.”
