Title: Industrial Policy under Constraints: Evidence from Pakistan’s Export Subsidy Schemes
Authors: Stefania Lovo, Gonzalo J. Varela
Series: World Bank Policy Research Working Paper 11136
Date: June 2025

Abstract Highlights

1. Policy Scope: Examines Pakistan’s export promotion policy (export subsidies), particularly the "Duty Drawback of Taxes" (DDT) scheme labeled as a key textile sector policy with a 55% export industry share.
2. Findings:
   • The policy boosted aggregated exports by a small amount, but funds were largely wasted due to product-specific reallocation.
   • Each $1 spent on DDT subsidized only $1.1 in exports, indicating inefficiency in budget allocation.
   • Aided shifts between high-, medium-, and low-rate products, with higher incentives generating strategic misreporting at customs.
3. Mechanisms: Evidence shows entry/exit compositions of exporters were altered, with capacity constraints affecting small firms negatively.

Methodology

• Data: 8/6-digit HS product codes and exporter transaction data from Pakistan and international sources.
• Method: Synthetic Control Method, event studies, and regression analysis to isolate policy impact.

Key Findings

1. Overall Impact:

   • Small positive effect on high-rate products (garments + madeups).
   • Negative effect on low- and very-low-rate products.
   • Overall net effect minimal, contributing to budget inefficiency.

2. Shifts in Trade Behavior:

   • Products targeted for higher rebates outperformed non-targeted.
   • Evidence of strategic misreporting, but its contribution was statistically insignificant.

3. Mechanisms:

   • Entry/exit effects shift toward higher-rate products, suggesting subsidies influenced product specialization.
   • Small firms face capacity constraints, inhibiting expansion into subsidized products.
   • Large exporters captured greater market share favoring high-rate products.

Conclusions & Policy Implications

1. Subsidy schemes alter product mixes, often diverting resources from generalized to specific subsidies.
2. Policymakers must balance:
   • Targeting products vs. broadening impact across the sector.
   • Short-term gains vs. long-term structural imbalances caused by selective incentives.
3. Policy design should consider potential for unintended reallocation, misreporting, and firm heterogeneity.

Markdown Summary

### Core Question  
Impact of targeted export subsidies on export performance and composition in Pakistan.  

### Method  
- Synthetic Control Method + Event Studies for pre/post trends.  
- Micro-data (product-level) to circumvent self-selection bias.  

### Findings  
1. **Positive effect limited** (1.9% annual increase on textiles) due to:  
   - Small aggregate impact, achieved at high fiscal cost.  
   - Uneven distribution across product categories.  
   - Strategic misreporting was insignificant but present.  
2. **Mechanisms**:  
   - Entry/exit shifts: New firms avoid low-rate products; exiting firms specialize in ineligible goods.  
   - Capacity constraints (funding/capital) hinder broader reallocation.  

### Policy Takeaways  
- Interventions may promote undue product concentration, increasing vulnerability.  
- Fiscal design should evaluate unintended reallocations and avoid fostering deceptive practices.  
- Capacity-building measures may mitigate inefficiency in policy delivery.
