History, regionalism, and CARICOM trade: A gravity model analysis
使用引力模型分析1980-1996年加勒比共同体成员国与贸易伙伴的双边数据，发现历史联系和区域主义显著影响贸易，人均收入和人口有正向作用，距离有负向作用。
Abstract A gravity model is fitted to 17 annual cross sections, 1980–1996, of bilateral trade data (imports and exports) between CARICOM member states and selected trading partners. Specifically, the paper investigates the effects of regional integration, colonial legacies and linguistic ties on CARICOM bilateral trade flows between member states and between member states and North American and European Union countries. The empirical results indicate that history and regionalism have had significant and strong effects on CARICOM trade. Additionally, two traditional explanatory variables in gravity models, income per capita and population, have significant and positive effects on CARICOM trade while the distance between trading partners exerts the expected negative effect.
