Policy Research Working Paper 10855: Trade Policies Mix and Match - Theory and Evidence
Overview:
The Policy Research Working Paper 10855 explores the intricate relationship between tariffs and non-tariff measures (NTMs) in international trade, focusing on how governments strategically mix these policies to achieve domestic objectives. The paper employs empirical evidence and theoretical models to analyze the dynamics of trade policy interactions, particularly in light of recent trade tensions and the shift towards NTMs in trade negotiations.
Key Findings:
-
Empirical Evidence: Utilizing detailed bilateral ad valorem equivalent (AVE) estimates of NTMs, the study finds that overall, tariffs and NTMs serve as policy substitutes, with governments imposing more restrictive NTMs on products or trading partners with lower tariffs. However, the relationship between tariffs and NTMs varies significantly based on characteristics of importing and exporting countries, as well as product types.
-
Interaction Factors:
- High-income Importing Countries: These economies tend to have more liberal tariffs but stricter NTMs.
- Low-income Exporting Countries: Similarly, these countries exhibit a pattern of more liberal tariffs and stringent NTMs.
- Deep Trade Agreements: Country pairs with strong trade ties often see lower tariffs paired with restrictive NTMs.
- Product Characteristics: Consumption products, agricultural products, and food and beverages are more likely to face policies that substitute tariffs with NTMs. Conversely, intermediate products and capital goods within global value chains (GVCs) often experience complementary trade policies.
-
Theoretical Model:
- A simple terms-of-trade model is introduced to explain the strategic use of tariffs and NTMs. This model demonstrates how a welfare-maximizing government might use these tools to mitigate negative consumption externalities from imports, aligning with Copeland's (1994) framework but focusing on the impact of NTMs on consumption rather than production.
Implications:
The findings underscore the complexity of trade policy decisions and highlight the importance of considering multiple factors when analyzing the effectiveness of tariffs versus NTMs. Policymakers need to navigate the balance between maintaining market access and protecting consumers from potential harms associated with imported goods. The empirical evidence supports the notion that trade policies are not static but dynamic, influenced by economic conditions, trade agreements, and policy objectives.
Methodology:
The paper employs advanced econometric techniques, including fixed-effects instrumental variable regressions, to analyze the data comprehensively. This approach allows for a nuanced understanding of the interplay between tariffs and NTMs, accounting for various country-specific and product characteristics.
Conclusion:
Policy Research Working Paper 10855 contributes to the ongoing discourse on trade policy by offering empirical insights and theoretical frameworks that elucidate the nuanced relationship between tariffs and NTMs. It underscores the strategic importance of understanding how different trade policies can be mixed and matched to address specific economic and social objectives, particularly in the context of evolving global trade dynamics.
