摘要
Natural and anthropogenic disasters frequently affect both the supply and demand side of an economy. A striking recent example is the Covid-19 pandemic which has created severe industry-specific disruptions to 經濟 output in most countries. Since firms are embedded in production 網絡s, these direct shocks to supply and demand will propagate downstream and upstream. We show that existing input-output models which allow for binding demand and supply constraints yield infeasible solutions when applied to pandemic shocks of three major European countries (Germany, Italy, Spain). We then introduce a 數學 optimization procedure which is able to determine best- case feasible market allocations, giving a lower bound on total shock propagation. We find that even in this best-case scenario 網絡 effects subs
