Economy 5.0: the ISHEA Index and the TACC cycle

This project presents Economy 5.0, a comprehensive framework to rethink economic measurement and decision-making in the 21st century. It integrates two original tools:

ISHEA (Expanded and Adjusted Human Satisfaction Index): a post-GDP metric that combines human well-being, adjusted progress, ecological sustainability, and governance.

TACC (Thin–Assim–Create–Check): a cognitive cycle for acting under stress, enriched with Stress, Rov (±r), Tram, and Key as adaptive learning and knowledge transfer mechanisms.

The project is structured in three complementary outputs:

1. Economy 5.0 — Measuring Differently to Decide Better
   The academic edition (main reference): includes methodology, variables, case studies, and scientific validation.

2. La Economía 5 — Narrative Edition
   The outreach edition: written in a more fluid and narrative style, with pedagogical anchors (TACC pauses, leitmotifs, bridges) and an epilogue with a “Gift from the Author.”

3. The Gift — Learning Guide for the 5.0 Ecosystem
   The practical manual: designed for classrooms, organizations, and communities. Includes the TACC game, the Key story, diagnostic tools, and printable annexes.

📌 Together, these three texts form an ecosystem of knowledge transfer:

The academic core (rigor and validation).

The narrative edition (public engagement).

The pedagogical guide (practice and training).

📑 Overview

Economy 5.0 is part of a broader research ecosystem designed to rethink economic measurement and human flourishing in the 21st century.
It integrates:

Principle +1 → universal law of negentropy.

ISHEA → a post-GDP index measuring well-being, adjusted progress, ecology, and governance.

TACC → a cognitive cycle for decision-making under stress.

Economy 5.0 → the applied framework bringing these tools into practice.

Relationship with the K Model

Economy 5.0 is nested within the K Model, which unifies theory, metrics, cognition, and application:

Principle +1: theoretical foundation (negentropy and systemic resilience).

ISHEA: the metric (Expanded and Adjusted Human Satisfaction Index).

TACC / Rov (±r): the cognitive and adaptive cycle under stress.

Lex (K as message): knowledge transfer and organized memory.

👉 In this architecture, the K Model = theory (+1) + measurement (ISHEA) + cognition (TACC) + application (Economy 5.0).

Components

Academic edition — Economy 5.0: methodological and validation framework.

Narrative edition — La Economía 5: public-facing, narrative book.

The Gift: pedagogical guide with stories and games.

Linked projects: Principle +1 (theory) and K Model (umbrella).

Project Goals

Provide a scientifically validated alternative to GDP.

Build tools for governments, businesses, and communities.

Transfer knowledge via academic, narrative, and pedagogical outputs.
