Then suppose that the coronavirus epidemic causes a persistent drop in productivity growth, from g to g'.

Imagine that the economy is initially at full employment (point ( g,l М…)). Note: Employment on horizontal axis productivity growth on vertical axis. This effect gives rise to a positive relationship between productivity growth ( g) and employment ( l), illustrated by the AD curve in Figure 1.ДЇigure 1 Impact of coronavirus on aggregate demand The reason for this is that faster productivity growth boosts agentsвЂ™ expectations of future income, inducing them to spend more in the present (Lorenzoni 2009). In turn, aggregate demand depends positively on productivity growth. As in the Keynesian tradition, employment and output are determined by aggregate demand. We take as our starting point a stripped-down version of the standard New Keynesian model (Gali 2009). The impact of coronavirus on aggregate demand 1В We show that the spread of the virus might cause a demand-driven slump, give rise to a supply-demand doom loop, and open the door to stagnation traps induced by pessimistic animal spirits. We focus on the (hopefully pessimistic) possibility that the supply disruption caused by COVID-19 will be severe and persistent. In Fornaro and Wolf (2020), we look at these questions through the lens of a simple model. But how deep and persistent is this supply disruption going to be? Will aggregate demand be affected? How should monetary policy respond? What about fiscal policy? The consensus is that the virus will cause a negative supply shock to the world economy, by forcing factories to shut down and disrupting global supply chains (OECD 2020). Besides its impact on public health, this coronavirus outbreak is likely to have significant economic consequences. As we write, the COVID-19 coronavirus is spreading throughout the globe.
