The study assesses the impact of the Forest Law Enforcement, Governance and Trade Voluntary Partnership Agreement (FLEGT VPA) and the Lacey Act Amendment (LAA) on the export quantities of wood products from Cameroon, Ghana and the Republic of Congo using the panel gravity Poisson Pseudo Maximum Likelihood (PPML) technique. The results indicate that FLEGT VPA had a negative and significant impact on industrial roundwood export quantity from all three countries. Similarly, its effects on the export of sawnwood and wood-based panels are also negative, except for Cameroon. On the other hand, the impact of LAA appears to be mixed. These results are validated by applying an alternative Driscoll-Kraay robust standard error estimation method.

木制品出口贸易法规的引力模型分析：来自喀麦隆、加纳和刚果共和国的证据


该研究使用面板重力泊松评估了《森林执法、治理和贸易自愿伙伴关系协议》(FLEGT VPA) 和《雷斯法案修正案》(LAA) 对喀麦隆、加纳和刚果共和国木制品出口数量的影响伪最大似然（PPML）技术。结果表明，FLEGT VPA 对这三个国家的工业原木出口量产生了显着的负面影响。同样，除喀麦隆外，其对锯木和人造板出口的影响也是负面的。另一方面，LAA 的影响似乎是复杂的。这些结果通过应用替代的 Driscoll-Kraay 稳健标准误差估计方法进行了验证。
