Asset-Universe Design and Action-Space Granularity in Cointegration-Based Deep Reinforcement Learning for Cryptocurrency Statistical Arbitrage

This study demonstrates that the out-of-sample performance of cointegration-based deep reinforcement learning for cryptocurrency statistical arbitrage is critically dependent on asset-universe construction and action-space granularity, with specific universe designs (such as Payment-Coin and Baseline 14) and binary action spaces yielding superior returns compared to broader universes or granular action specifications.

Machine Learning Feature Importance vs. Fixed-Effects Regression: Which Variables Actually Drive CSR–Firm Value Relationships in Africa?

This study demonstrates that combining machine learning feature importance with fixed-effects regression reveals critical nonlinearities and interaction effects—such as thresholds in board independence and context-dependent CEO duality—that traditional linear models overlook, thereby offering a superior two-step framework for understanding the drivers of CSR-firm value relationships in African financial markets.
