Economic Activity across Space: A Supply and Demand Approach
展示经济活动的空间分布可由劳动力供需曲线的交点决定，并讨论如何估计这些曲线，强调全球地理（即通过贸易网络连接的地点）在塑造空间经济中的重要性。
What do recent advances in economic geography teach us about the spatial distribution of economic activity? We show that the equilibrium distribution of economic activity can be determined simply by the intersection of labor supply and demand curves. We discuss how to estimate these curves and highlight the importance of global geography—the connections between locations through the trading network—in determining how various policy relevant changes to geography shape the spatial economy.
