Growth Due To Globalization*
构建了一个包含地理空间和运输成本的增长模型，其中企业销售区域是内生的，解释了开放度与收入的正相关关系以及开放度与增长的非稳健相关性。
This article presents a growth model including geographical space and transportation costs in which the geographical area where firms sell their product is endogenous. Growth is generated by the expansion of trade and there is a positive relationship between degree of openness and income level. The model explains why economies become increasingly more open and why the degree of openness is not robustly correlated with growth. In contrast to other growth models, investment in transport infrastructure plays an important role and the size of the country does not affect growth.
