Spatial macroeconomics

This special issue on spatial macroeconomics aims to bridge the divide between spatial and macroeconomics. Defined in the introduction, spatial macroeconomics explores the interactions between economic activity and geographical space. The issue comprises eleven papers authored by a total of 32 researchers. These papers were selected through a combination of solicited submissions and an open call for contributions. Four papers within this special issue delve into spatial macroeconomic theory. They cover topics such as agglomeration economies for innovation, a neoclassical spatial general equilibrium growth model, the spatial sorting of heterogeneous workers and the impact of national industrial policies in strategic industries on trade. Additionally, seven papers offer empirical studies that encompass a wide range of methodologies. These include general equilibrium models, input-output-based analyses and econometric models. The empirical research addresses various topics, such as the impact of trade on productivity, the trade-off between efficiency and equity, fiscal assistance, local and nationwide fiscal multipliers, forced human displacement during wars and the spatial diffusion effects of renewable energy resource deployment.
