The Effect of Airbnb on Housing Prices: Evidence From the 2017 Solar Eclipse
Journal of Regional Science, EarlyView.ABSTRACT This study exploits the 2017 solar eclipse as a natural experiment to estimate the causal impact of Airbnb activity on housing prices. The eclipse created a temporary demand shock that induced a persistent increase in Airbnb supply. Using an IV/2SLS framework, we find that a 1% increase in Airbnb listings raises housing prices by 0.037%–0.043%,

Reinforcement Learning for Jump‐Diffusions, With Financial Applications
Mathematical Finance, EarlyView.ABSTRACT We study continuous‐time reinforcement learning (RL) for stochastic control in which system dynamics are governed by jump‐diffusion processes. We formulate an entropy‐regularized exploratory control problem with stochastic policies to capture the exploration–exploitation balance essential for RL.

On the Exact Limiting Distribution of a Volatility Target Index
Mathematical Finance, EarlyView.ABSTRACT Assuming a lognormal distribution for the underlying risky asset, we study the limiting distribution of a volatility target index as the rebalancing time step approaches zero. Two limit theorems (a strong law of large numbers and a central limit theorem) are established, and as an application, the exact limiting distribution is derived.
