We apply our theory to global value chains (GVCs) and trade, where firms strike a balance between the productivity gain from longer GVCs against the greater financial cost due to longer supply chains. In equilibrium, we show the duality between GVC length and financial conditions, where more accommodative financial conditions are associated with longer GVCs.
