The 1920-21 Deflation: The Role of Aggregate Supply


  • Vernon, J R


World War I was followed by an extremely sharp deflation in 1920-21. Most treatments have attributed this deflation to a decline in aggregate demand. This paper, noting that the deflation was not only large, but large relative to the accompanying decline in real product, argues that it was caused by a decline in aggregate demand combined with an increase in aggregate supply.
