疫情中的社交距离与供给中断AI 解读

We integrate an epidemiological model, augmented with contact and mobility analyses, with a two‐sector macroeconomic model, to assess the economic costs of labor supply disruptions in a pandemic. The model is designed to capture key characteristics of the U.S. input–output tables with a core sector that produces intermediate inputs not easily replaceable by the other sectors, possibly subject to minimum‐scale requirements. Using epidemiological and mobility data to inform…

含偶尔生效约束模型的似然计算AI 解读

Summary Applied researchers interested in estimating key parameters of dynamic stochastic general equilibrium models face an array of choices regarding numerical solution and estimation methods. We focus on the likelihood evaluation of models with occasionally binding constraints. We document how solution approximation errors and likelihood misspecification, related to the treatment of measurement errors, can interact and compound each other.
