Does US trade liberalization explain Puerto Rico’s deindustrialization?

This paper studies the possible role of US trade liberalization in explaining Puerto Rico's deindustrialization. In order to address this issue, time series techniques were used. The results of the Granger Causality Test suggest that the imports made by the US from Mexico, Canada, Ireland, and Costa Rica do not explain Puerto Rico's deindustrialization. Therefore, no causal relationship was found between the imports made by the US from its NAFTA partners and the countries where the corporations that benefited from Section 936 relocated with the deindustrialization of Puerto Rico. Besides, the impulse response exercise suggests that in the first period, deindustrialization explains its variability by 100%, and in the final period, it explains 95.47%
