    Abstract

    This paper investigates the impact of an export promotion policy consisting of ad-valorem subsidies for a set of targeted products, on the performance of Pakistani exports in the textile sector. The findings show that the policy had a small overall impact on exports, while it induced substantial reallocation of exports across products. The policy induced an increase in exports of traditional products, mostly garments, which were eligible for the highest rebate rates, at the expense of non-eligible or lower-rated products. The paper presents suggestive evidence indicating that the observed effects are partially attributed to shifts in the composition of exporters, through exits and entries alongside capacity constraints. Finally, the evidence shows that the scheme induced strategic misreporting at the border, which contributed marginally to the overall effects.

    Source: The United Nations, UN Comtrade, accessed via the WITS Portal. Date of Access: May 2021. File Location: Input/Export_HS6.csv and Export_toEU_HS6.csv; PAK_export_to_top20_all_08_10.csv; PAK_export_to_top20_all_11_15.csv; PAK_export_to_top20_all_16_19.csv, Top20imports_from_PAK_all_09_14.csv; Top20imports_from_PAK_all_15_19.csv. The data was retrieved through a query on the UN Comtrade database using the World Integrated Trade Solution (WITS) portal. Instructions on how to reproduce the exact queries can be found in the README. The package also includes a data folder structure to help users locate and, if necessary, re-download the data. Please note that this data is regularly updated. The reviewers attempted to verify whether the publicly available version of the data matched the one used in the original analysis, but found that the public version had since been updated and has some differences from the version used by the authors. Hashes for the datasets are included in the reproducibility package for verification purposes.
