Predictive regression methods are widely used to examine the predictability of (excess) stock returns by lagged financial variables characterized by unknown degrees of persistence and endogeneity. We develop a new hybrid test for predictability in th... Read More about Improved tests for stock return predictability.

Bonferroni Type Tests for Return Predictability and the Initial Condition (2023)
Journal Article
Astill, S., Harvey, D. I., Leybourne, S. J., & Taylor, A. M. (2024). Bonferroni Type Tests for Return Predictability and the Initial Condition. Journal of Business and Economic Statistics, 42(2), 499-515. https://doi.org/10.1080/07350015.2023.2201313

We develop tests for predictability that are robust to both the magnitude of the initial condition and the degree of persistence of the predictor. While the popular Bonferroni Q test of Campbell and Yogo displays excellent power properties for strong... Read More about Bonferroni Type Tests for Return Predictability and the Initial Condition.

Real-Time Monitoring of Bubbles and Crashes (2023)
Journal Article
Whitehouse, E. J., Harvey, D. I., & Leybourne, S. J. (2023). Real-Time Monitoring of Bubbles and Crashes. Oxford Bulletin of Economics and Statistics, 85(3), 482-513. https://doi.org/10.1111/obes.12540

Given the financial and economic damage that can be caused by the collapse of an asset price bubble, it is of critical importance to rapidly detect the onset of a crash once a bubble has been identified. We develop a real-time monitoring procedure fo... Read More about Real-Time Monitoring of Bubbles and Crashes.
