What is Ricardo J. Caballero known for in economics?

I am known for my work on understanding how individual market imperfections can lead to large-scale macroeconomic fluctuations and financial crises. My research has focused on the role of 'aggregate demand externalities' and 'financial frictions,' aiming to explain why economies can experience sudden downturns even without obvious external shocks. I've also been involved in applying these theoretical insights to real-world policy questions, particularly concerning crisis management.
