Asian Journal of Applied Economics/ Applied Economics Journal, 2026, vol. 33, issue 1 Abstract: Background and Objectives: Cross-border trade plays an increasingly important role in supporting agricultural exports in Southeast Asia, particularly for countries with extensive shared land borders. For Thailand, agricultural trade with neighboring countries—Cambodia, Lao PDR, Myanmar, and Malaysia—has become a critical alternative market that helps reduce reliance on traditional export destinations and enhances regional food security. Despite the long-standing implementation of tariff liberalization under the ASEAN Free Trade Area (AFTA), cross-border agricultural trade in the region continues to face significant structural and institutional constraints, including inadequate border infrastructure, complex customs procedures, political instability, and evolving non-tariff barriers. Existing empirical studies on Thailand’s border trade have largely focused on traditional gravity variables or qualitative assessments, while relatively limited attention has been paid to the comparative role of trade facilitation mechanisms and governance-related factors. This study aims to examine the structural and institutional determinants of Thailand’s cross-border agricultural exports and to identify the most effective mechanisms for promoting trade expansion under conditions of logistical constraints and regional uncertainty. By distinguishing between traditional economic drivers and modern trade facilitation and institutional factors, the study seeks to provide policy-relevant insights for strengthening Thailand’s role as a regional food hub. Methodology: The study employs an augmented gravity model estimated using the Poisson Pseudo Maximum Likelihood (PPML) method with fixed effects. This estimation technique is chosen to address heteroskedasticity, mitigate Jensen’s inequality bias, and accommodate zero trade flows without losing information. The empirical analysis covers the period from 1989 to 2024 and focuses on Thailand’s agricultural exports to its four neighboring countries with shared land borders. Agricultural products are classified into five major groups: live animals and animal products, plant products, animal and vegetable fats and oils, prepared foodstuffs, and rubber and rubber products. The model incorporates conventional gravity variables—such as GDP, population, and distance—alongside border-specific and institutional variables, including the number of border crossing points, the implementation of AFTA, the establishment of the ASEAN Trade Facilitation Joint Consultative Committee (AFTJCC), and governance indicators. Major macroeconomic shocks, including the 1997 Asian financial crisis, the 2008 global financial crisis, and the COVID-19 pandemic, are also controlled for to capture external disruptions affecting regional trade dynamics. Key Findings: The empirical results reveal that the expansion of border crossing points is the most influential determinant of Thailand’s cross-border agricultural exports, particularly for live animals and animal products. This finding underscores the critical importance of physical accessibility and border infrastructure in facilitating agricultural trade, especially for perishable and time-sensitive products. Among institutional factors, the establishment of the AFTJCC has a significant positive effect on rubber exports, while the impact of AFTA tariff liberalization appears relatively limited across most product groups. This pattern suggests a structural shift from tariff-based barriers toward non-tariff obstacles, such as customs procedures, regulatory complexity, and infrastructure bottlenecks. In addition, the study finds a positive association between political instability in neighboring countries and Thailand’s exports of live animals and plant products, reflecting heightened demand driven by food security concerns during periods of regional uncertainty. Governance-related variables exhibit heterogeneous effects across product categories, indicating that improveme Keywords: Border Trade; Exports; Agricultural Products; Thailand (search for similar items in EconPapers) Downloads: (external link) Related works: Export reference: BibTeX RIS (EndNote, ProCite, RefMan) HTML/Text Persistent link: https://EconPapers.repec.org/RePEc:ris:apecjn:022407 Access Statistics for this article Asian Journal of Applied Economics/ Applied Economics Journal is currently edited by Waleerat Suphannachart More articles in Asian Journal of Applied Economics/ Applied Economics Journal from Kasetsart University, Faculty of Economics, Center for Applied Economic Research Center for Applied Economics Research, Faculty of Economics, Kasetsart University, Bangkok, 10900, Thailand.
