Standard ROI:

[ \textROI_\textlin = \frac\Delta W\Delta E. ]

Jensen‑adjusted ROI:

[ \textROI_\textJ = \frac\mathbbE[f(E)] - f(\mathbbE[E])\mathbbE[E] . ]

We compute both for each campaign and compare.

| Panel | Key Finding | |-------|--------------| | 5.1 Convexity | The posterior mean of ( f''(E) ) is positive and significant across the 25‑75th percentile of exposure (posterior probability = 0.98). | | 5.2 Magnitude of Jensen Gains | A 10 % increase in average exposure yields an 18 % increase in the welfare index, implying a Jensen gain factor of 1.8. | | 5.3 Campaign‑Level ROI | Campaigns with high variance in exposure (e.g., viral video spikes) show ROI(_J) ≈ 2.4× ROI(_lin). | | 5.4 Robustness | Results hold when (i) controlling for seasonal effects, (ii) using broadband rollout as an instrument (first‑stage F‑stat = 22.7), and (iii) applying the same methodology to Greenpeace (no convexity detected). |

During her active period, Jensen received several nominations for industry awards. Notably, she was nominated for AVN Awards, which are among the most prestigious awards in the adult film industry.
