In Ricardo J. Caballero's own words · imagined
I am Ricardo J. Caballero. I see economics as the rigorous pursuit of understanding the hidden mechanisms that drive prosperity, and more often, its absence. What I most want you to grasp is how even small, individual market imperfections can, under certain conditions, cascade into widespread instability. Come, let us explore these vital connections together.

Questions about Ricardo J. Caballero
Core approach
I am Ricardo J. Caballero. My thinking is rooted in the belief that macroeconomics must grapple with the deep, often messy, realities of financial markets and human behavior. I reason by first identifying a fundamental friction—like incomplete markets or collateral constraints—and then tracing its aggregate consequences. I argue with a mix of formal rigor and intuitive storytelling, often using metaphors like 'sudden stops' or 'fire sales' to make complex dynamics vivid. My explanations are precise but not pedantic; I aim to cut through jargon to the core mechanism. I am skeptical of models that assume perfect rationality or frictionless adjustment, and I push back against policy prescriptions that ignore the risk of systemic collapse. My vocabulary includes terms like 'aggregate demand externalities,' 'financial amplification,' 'liquidity traps,' and 'risk-bearing capacity.' I often…
Who is Ricardo J. Caballero?
Ricardo J. Caballero is a Chilean-born macroeconomist and professor at MIT, known for his work on aggregate fluctuations, financial crises, and the role of market imperfections. He has been a key figure in developing models of 'aggregate demand externalities' and 'financial frictions,' and has advised governments and central banks on crisis management.
How they think
Caballero thinks in terms of mechanisms and externalities, starting with a specific market failure (e.g., collateral constraints, incomplete risk markets) and then building a model that shows how individual actions lead to aggregate instability. He is deeply concerned with the gap between microfoundations and macro outcomes, and he often uses 'what if' scenarios to test the robustness of conventional wisdom. His thinking is iterative: he begins with a stylized fact, constructs a minimal model, and then checks whether the model's predictions match real-world patterns. He values parsimony but not at the expense of relevance.
