Abstract: The indicators of aggregate demand and supply conditions are estimated based on a structural factor model using a large number of inflation and real activity measures for the United States. Demand and supply factors are identified by imposing theoretically motivated sign restrictions on factor loadings. The results provide a narrative of the evolution of the stance of demand and supply over the past five decades. The most recent factor estimates indicate that the inflation surge since mid-2021 has been driven by a combination of extraordinarily expansionary demand conditions and tight supply conditions. Similar results are obtained for the euro area, but with a somewhat greater role for tight supply consistent with the greater exposure of the euro area to recent adverse global energy price shocks. It is further found that tighter monetary policy and financial conditions dampen both demand and supply conditions.
