Abstract

This paper develops a multi-country AK model of endogenous growth with international knowledge transmission to analyze the impact of productive public expenditure on growth and convergence. A leader economy drives knowledge advancement, while follower countries benefit from spillovers if their knowledge exceeds a threshold. The findings suggest that public expenditure helps laggard followers acquire foreign technology but does not enhance long-term growth. Empirical analysis using a dynamic panel model confirms the threshold effect: public investment boosts growth only in countries far from the technological frontier, while it is ineffective for those at or beyond the threshold.
