ABSTRACT

This short note has one main ambition. It seeks to provide students with a very simple macroeconomic framework to deal with the short-term economic impact of the COVID-19 pandemic. The explanation for the unprecedented magnitude of the recession over a short span of time is to be found in the peculiar form of the shock due to the various lockdowns. Indeed, the 2020 crisis is specific in that it involved two recessive shocks simultaneously: a demand shock superimposed on a supply shock. This model is original in that although it is driven by demand it is capable of dealing with supply issues without entailing any additional technical difficulties.

用简单的短期宏观模型教授 COVID-19 的经济影响:同时发生的供需冲击

摘要

这篇简短的笔记有一个主要的抱负。它旨在为学生提供一个非常简单的宏观经济框架,以应对 COVID-19 大流行的短期经济影响。在短时间内出现前所未有的经济衰退程度的原因,可以从各种封锁造成的特殊冲击形式中找到。事实上,2020 年危机的特殊性在于它同时涉及两个隐性冲击:需求冲击叠加在供应冲击上。这种模式是原创的,虽然它是由需求驱动的,但它能够处理供应问题,而不会带来任何额外的技术困难。
