Abstract

This research paper investigates the effectiveness of policy intervention stages onmacroeconomic and social indicators using a Multivariate Analysis of Variance (MANOVA) framework. The study evaluates the Country Policy and Institutional Assessment (CPIA) stages across three intervention phases: Pre-CPIA Improvement, CPIA Reform Implementation, and Post-CPIA Reform Consolidation. The analysis covers 27 countries, assessing changes in economic and social outcomes. While the multivariate tests show no significant overall differences across stages, univariate analyses highlight notable variations in specific countries, suggesting that targeted interventions during critical phases yield measurable improvements.
