“…Strong research efforts have examined the above arguments on the role of imperfections in the link between internal cash flows and investment flows (Kaplan and Zingales, ), for small firms, especially during times of financial stress (Campello et al, ; Fort et al, ), in the link between internal cash flows and asset prices (Gan, ; Chaney et al, ), credit constraints for firms and households (Gertler and Gilchrist, ), the inability of household to borrow (Jappelli and Pistaferri, for a review), house prices and households’ borrowing (Almeida et al, ; Claessens and Kose, ), housing prices and local credit and growth developments (Mian and Sufi, ; Benmelech et al, ), the ability of sovereign nations to borrow from international markets (Obstfeld and Rogoff, ; Ferraris and Minetti, ; Korinek and Mendoza, ), the impact on countries’ exchange rates (Aghion et al, ; Cook, ), the transmission process of business cycles (Guerrieri et al, ), and finally, in explaining the synchronized nature of the 2008 financial crisis (Kalemli‐Ozcan et al, ; Quadrini, ).
