Externalities in the agricultural export sector and economic growth: a developing country perspective
构建理论模型分析非传统农业出口部门与长期经济增长的关系，以哥伦比亚水果和花卉产业为例，说明高易腐性农产品出口可能比国内制造业更能促进长期增长。
Abstract For years economists have ignored the diversity in agriculture and its potential to increase long run growth rates by enhancing a country’s knowledge base. Non-traditional agriculture requires significant investments in the infrastructure and knowledge; and therefore, has the potential to increase long run growth rates. Policy makers in developing countries have tended to enact macroeconomic policies designed to enhance the manufacturing sector at the expense of the agricultural sector. A theoretical model is developed to explain the dynamics between two non-traditional export sectors and the long run economic growth of the country. The model illustrates that growth in highly perishable agricultural exports, not domestic production of manufactured goods, can potentially lead to higher long run growth rates. The model is applied to the fruit and flower industries in Colombia to bring forth an example with real world relevance.
