Macroeconomics and regional science have developed as separate disciplines. However, the fact that the gross domestic product is the sum of gross regional products suggests that the two disciplines are related. The present study considers the implications of regional science and economic geography for macroeconomics. Specifically, a spatial econometric model for Israel is simulated to explore the implications of regional productivity and amenity shocks for gross regional products and the gross domestic product. We show that the effects of productivity shocks on the gross domestic product depend on where they occur and may even be negative. These results question estimates of the effect of productivity shocks in macroeconomic models in terms of spatial aggregation bias. They also provide empirical evidence rejecting the spatial granularity hypothesis regarding the secular relation between macroeconomic economic activity and regional economic activity. The study concludes with speculations about the implications of macroeconomics for regional science.

宏观经济学和区域科学已经发展成为独立的学科。然而，国内生产总值是地区生产总值的总和这一事实表明这两个学科是相关的。本研究考虑了区域科学和经济地理学对宏观经济学的影响。具体而言，模拟了以色列的空间计量经济模型，以探讨区域生产力和舒适性冲击对区域生产总值和国内生产总值的影响。我们表明，生产率冲击对国内生产总值的影响取决于它们发生的地点，甚至可能是负面的。这些结果质疑宏观经济模型中生产力冲击对空间聚合偏差影响的估计。他们还提供了实证证据，拒绝了关于宏观经济活动与区域经济活动之间长期关系的空间粒度假设。该研究最后对宏观经济对区域科学的影响进行了推测。
