“…In a theoretical model, Kumhof, Rancière, and Winant (2015) show that higher savings of the rich may lead to a decline in interest rates, which leads to higher borrowing by low-and middle-income households and higher financial fragility. However, Coibion et al (2020) find that low-income households face higher borrowing costs and reduced access to credit as inequality increases. Adelino, Schoar, and Severino (2016) and Albanesi, De Giorgi, and Nosal (2017) provide complementary evidence on the debt boom during the 2000s and highlight the important role of the middle class for the debt boom during these years.…”
