The effect of optimal investment by stock options incentive under economic policy uncertainty

This study shows that executive stock options are an effective compensation policy that takes corporate investment to the optimal level in the presence of unpredictable risk from economic policy uncertainty (EPU).

We use delta and vega as a proxy for price sensitivity and compensation sensitivity, respectively, to examine the interaction between executive stock options portfolio and EPU. We use delta for price sensitivity and vega for compensation sensitivity, respectively, to examine the interaction between executive stock options portfolio and EPU.
