A LONG‐RUN INTERPRETATION OF REGIONAL INPUT‐OUTPUT ANALYSIS*
论证了包含内生投资的投入产出系统能复制多种区域模型的长期均衡，并用可计算一般均衡框架展示了需求冲击下投入产出与标准新古典模型结果趋同。
ABSTRACT. Regional input‐output (I‐O) analysis is traditionally motivated by a short‐run, extreme Keynesian vision of markets. In this paper we argue that an appropriately formulated, investment‐endogenous, I‐O system replicates the long‐run equilibria of a wide range of regional models, many of which do not operate as I‐O systems in the short run. In particular, we use a computable general equilibrium (CGE) framework to illustrate the impact of an aggregate demand disturbance on an I‐O and standard neoclassical model. When run forward over a number of periods, the results from the capacity‐constrained neoclassical model asymptotically approach the I‐O outcome. We use sensitivity analysis to examine the speed of adjustment of the neo‐classical system and investigate barriers to the attainment of the I‐O result.
