Modelling NIE exports: Aggregation, quantitative restrictions and choice of econometric methodology
通过建模韩国制成品出口，研究出口需求与供给弹性估计的稳健性，发现加总层次高且包含数量限制类别时存在偏差，并强调小国假设在正确建模下更可能获得实证支持。
The current debate regarding the robustness of estimates of export demand and supply elasticities for NIEs is examined by modelling manufactured exports from Korea. The results suggest that normalisation of the export demand function for price rather than quantity is an important issue in estimating export demand functions of small countries, and that estimates of export demand elasticities at high levels of aggregation are subject to potentially powerful biases, when the aggregate consists of categories which are subject to quantitative restrictions. If proper modelling procedures are followed, it is likely that the small country assumption will find far more empirical support than it has hitherto.
