摘要翻译：
这项工作的目的有两个：扩展托宾提出的萧条模型，并在凯恩斯主义的概念环境中分析供应冲击，如新冠肺炎疫情。扩展允许我们提出所有内生宏观经济变量的演变。所得结果具有一定的理论和实际意义。对冲击的数量或凯恩斯主义调整通过对总需求的影响产生萧条。这种萧条在中期/长期内恶化。它伴随着通货膨胀、通货膨胀预期和实际利率的上升。还建议采取刺激税收政策，以及积极的货币政策来降低实际利率。另一方面，定价或马歇尔调整预计短期内将出现更严重和更迅速的萧条。通胀和通胀预期将会降低，实际利率将会上升。税收或货币刺激措施只会影响通胀。这一结果使得澄清和评估由此产生的萧条以及提出政策成为可能。最后，它提供了相互矛盾的预测，允许两个模型中的一个被证伪。

英文摘要：
  The objective of this work is twofold: to expand the depression models proposed by Tobin and analyse a supply shock, such as the Covid-19 pandemic, in this Keynesian conceptual environment. The expansion allows us to propose the evolution of all endogenous macroeconomic variables. The result obtained is relevant due to its theoretical and practical implications. A quantity or Keynesian adjustment to the shock produces a depression through the effect on aggregate demand. This depression worsens in the medium/long-term. It is accompanied by increases in inflation, inflation expectations and the real interest rate. A stimulus tax policy is also recommended, as well as an active monetary policy to reduce real interest rates. On the other hand, the pricing or Marshallian adjustment foresees a more severe and rapid depression in the short-term. There would be a reduction in inflation and inflation expectations, and an increase in the real interest rates. The tax or monetary stimulus measures would only impact inflation. This result makes it possible to clarify and assess the resulting depression, as well as propose policies. Finally, it offers conflicting predictions that allow one of the two models to be falsified.
