To estimate (4), we need data on four variables: income (Y), international trade (T), size (S),and proximity (P).We measure the first three in the usual ways. Our measure of income is real income per person. Following standard practice, we measure international trade as imports plus exports divided by GDP. This is clearly an imperfect measure of economic interactions with other countries, as issue we return to in section 2, subsection E. Finally, theory provides little guidance about the best measure of size. We therefore use two natural measures,population and area, both in logs. In interpreting the results concerning size, we focus on the sum of the coefficients on log population and log area. Thus we consider the impact of an increase in population and area together, with no change in population density. Such a change clearly increases the scope for within-country trade.

估计( 4 ) ,我们需要的数据四个变量:收入(年) ,国际贸易(吨) ,大小( s )和近距离(规划) 。我们衡量前三通常方式。我们衡量收入是真实的人均收入。下列标准的做法,我们衡量国际贸易的进口加出口除以国内生产总值。这显然是一个不完美的程度的经济互动与其他国家,因为我们回到问题的第2款,第 最后,几乎没有提供理论指导的最佳衡量标准尺寸。因此,我们使用两种自然的措施,人口和面积方面,无论是在日志。在解释有关的成果大小,我们把重点放在的总和,人口系数日志和日志领域。因此,我们考虑的影响,增加了人口和面积方面的合作,没有任何变化,人口密度。这种变化显然增加了范围内的贸易。
