The impact of trade reforms on industry wage premia in Pakistan: A sectoral perspective

Pakistan witnessed significant trade liberalization reforms between 1988 and 2005. This study investigates the impact of Pakistan's significant trade liberalization policies in 1988 on industry wage premia. We use an estimation strategy that takes into account dispersion in sector wage premiums and trade reforms over time and across sectors. We employed the wage premium approach and Restricted Least Squares to obtain sectoral wage premia. We used weighted least squares and two-stage-least-squares (2SLS) to explore the liaison between trade reforms and sector wage premia. Contrary to previous empirical studies on less developed economies, our findings reveal a significant and resilient correlation between changes in trade reforms and fluctuations in sector wage premiums during the liberalisation period of 1990-2005. Our findings are consistent with short- and medium-run trade models in which workers are immobile across industries or, on the other hand, with the presence of sector rents that are reduced when trade policy is liberalized.
