This research develops a new econometric method that captures complex, non-linear relationships while accounting for hidden differences between firms. Applied across 50 industries, it reveals that traditional models underestimate R&D investment by up to 8%, enabling more accurate economic predictions and better-designed innovation, taxation, and regulatory policies.

This research shows that toxic behavior in online games is contagious, especially from teammates. Using machine learning and econometric analysis of 300,000 messages, it finds toxicity spreads socially rather than individually. The study suggests that effective interventions should target breaking transmission patterns rather than simply punishing players to improve online environments.
