AERI principally means AI Empowerment and Replacement Index in the thesis. Other passages expand it as AI-ESG Relationship Index or AI ESG Responsibility Index. These naming variants belong to the original text and do not describe separate validated models.
The proposed Productivity Impact Score is PIS = (output increase + time savings + error reduction + cost savings) / 4, with equally weighted components. The thesis suggests questionnaires to collect input, but does not establish how their ordinal answers translate into the percentage measures in this formula (physical PDF pages 35–37, printed pages 31–33).
The proposed annual AI Workforce Replacement Index is ARI_y = 100 × (AI-related hires_y − AI-related firings_y) / workforce_y. Its sign follows net hiring in the stated equation, so a positive value means net hiring and a negative value means net firing. The denominator and the causal attribution of an event need a consistent definition (physical pages 38–39, printed pages 34–35).
The stated Long-Term Behavior formula is LTB = Σ(ARI_y × y / n), placing greater weight on later years. The final combined expression is AERI = E × We + (S + PIS) × Ws + (G + LTB) × Wg. The earlier expression on physical page 41 places weights differently, so the final expression alone does not resolve every ambiguity (physical pages 39–42, printed pages 35–38).
