Replication Workbook for the Composite Investment-Unemployment Multiplier (MIU = βθ): A Monte Carlo Calibration Across Four Stylized Economic Archetypes

This repository contains the complete formula-driven Excel replication workbook accompanying the paper "The Composite Investment-Unemployment Multiplier: A Theoretical and Policy Framework for Understanding Employment-Generating Growth" (MIU = βθ), by Imadeddin Ahmed Almosabbeh, submitted for peer review and publication. The workbook implements the illustrative numerical calibration and Monte Carlo simulation exercise reported in Section 7 of the paper. It generates stochastic distributions of the Composite Investment-Unemployment Multiplier (MIU = βθ), the structural constant (c = a₁ − βa₀), and the critical investment threshold (I/Y*) under four stylized economic archetypes representing distinct combinations of capital efficiency (θ) and employment elasticity (β): [rentier/extractive economy, industrial/manufacturing economy, automation-intensive economy, transitional/labour-abundant economy]. All parameter ranges, probability distributions, and simulation formulas are fully transparent and editable within the workbook, allowing exact reproduction of every table and figure reported in Section 7. No external or proprietary data sources were used; all inputs are theoretically motivated parameter calibrations disclosed in full within the workbook itself. Users are free to adjust parameter values to test alternative structural assumptions or extend the model to additional country archetypes.
