Do market-oriented reforms cause economic growth? This paper revisits this question using a cross-country panel of reform episodes identified from various changes in well-known economic freedom and structural reform indices. We exploit the timing of reforms using distributed-lag and event-study frameworks that trace the dynamic response of per-capita GDP. We find little evidence of immediate growth gains and some short-run adjustment costs following reform. However, growth rises gradually and persistently over time, with economically meaningful effects emerging after several years. These patterns are robust across alternative measures of reform and specifications. The results reconcile conflicting findings in the literature by showing that market reforms generate long-run growth gains despite short-run disruptions. Overall, the evidence supports the view that institutional liberalization operates through slow-moving channels that accumulate into sustained improvements in economic performance.…
