- Abstract
- Does artificial intelligence (AI) pose a threat to financial stability? We study AI investor behavior, specifically Q-learning and large language model (LLM) investors, in a mutual fund redemption problem with economic and strategic uncertainty. Different AI architectures generate systematically different outcomes. Q-learning investors coordinate well but under default risk exhibit excessive redemption that amplifies fragility. LLM investors internalize equilibrium structure but display belief heterogeneity, weakening coordination and predictability. Our findings show that AI architecture is a first-order determinant of financial stability.

- Abstract
- How do real interest rates affect financial fragility? We study this issue in a model in which bank borrowing is subject to rollover risk. A bank’s optimal borrowing trades off the benefit from investing additional funds into profitable assets with the cost of greater risk of a run by bank creditors. Changes in the interest rate affect the price and amount of borrowing, both of which influence bank fragility in opposite directions. Thus, the marginal impact of changes to the interest rate on bank fragility depends on the level of the interest rate. Finally, we derive testable implications that may guide future empirical work.
