上期回顾
We reviewed the foundational assumptions of a closed economy with a supply chain network. We derived the relationship between the Domar weights and the production input network. Also, we solved for the optimal investment of the manufacturer. On this basis, we derived the expression for the output gap using Domar weights and productivity shocks.
本期预告
We will perform linear logarithmic expansion on the steady-state equations. Furthermore, we will derive the IS curve and Phillips curve in the context of a multi-industry supply chain network. Analytical expressions for the Phillips curve and welfare, derived as a function of primitives, show that the slopes of all sectoral and aggregate Phillips curves are decreasing in intermediate input shares, while productivity fluctuations endogenously generate an inflation-output tradeoff, except when inflation is measured according to the novel divine coincidence index.
