The integration of algorithmic trading and reinforcement learning, known as AI-powered trading, has significantly impacted capital markets. This study utilizes a model of imperfect competition among informed speculators with asymmetric information to explore the implications of AI-powered...

Using local natural disasters as a quasi-experimental setting, we show that heightened distress risk in shocked firms drives both these firms and their unshocked competitors to cut profit margins by about 0.8 percentage points. These reductions stem from predatory pricing, inventory liquidation,...

The integration of algorithmic trading with reinforcement learning, termed AI-powered trading, is transforming financial markets. Alongside the benefits, it raises concerns for collusion. This study first develops a model to explore the possibility of collusion among informed speculators in a...

We develop an endogenous growth model with heterogeneous firms facing financial frictions, where misallocation emerges explicitly as a crucial endogenous state variable and plays a significant role in driving economic growth through the valuation channel. The model illustrates that transient...

We document robust industry return predictability through the lens of a competition network, connecting two industries that share a multi-industry market leader. Equity returns in an industry exhibit a delayed response to cross-industry effects due to investors' limited attention and constrained...

Investment fund managers make asset allocation decisions on behalf of a significant segment of US households. To elucidate the incentives they operate under, as well as the income and career risks they face, we construct a unique and novel dataset, which encompasses detailed information on the...

Firms tend to compete more aggressively in financial distress; the intensified competition in turn reduces profit margins, pushing themselves further into distress and adversely affecting other firms. To study such feedback and contagion effects, we incorporate strategic competition into a...
