This paper gives a decomposition of GDP and its deflator into demand and provide pushed elements for 12 Asian international locations, the US and Europe, following the forecast error-based methodology of Shapiro (2022). We prolong that methodology by (1) contemplating a variety of statistical forecasting fashions, utilizing the optimum mannequin for every nation and (2) present a measure idiosyncratic demand and provide actions. The latter gives, for instance, a distinction between mixture demand pushed inflation and, inflation pushed by giant shocks in solely a small variety of sectors. We discover that lockdowns in 2020 are defined by a mixture of demand and provide shocks in Asia, however that idiosyncratic demand shocks performed a big position in some international locations. Provide elements performed an vital position within the post-COVID restoration, primarily in 2021, with demand elements turning into extra vital in 2022. The combination of shocks in the course of the sharp enhance in inflation in 2021-22 differs by nation, with giant and superior economies typically experiencing extra provide shocks (China, Australia, Korea), whereas rising markets noticed important demand pressures pushing up costs (Indonesia, Malaysia, Philippines, Vietnam, Thailand). We illustrate the usefulness of the trade stage shocks in two purposes. Firstly, we contemplate whether or not trade provide shocks have created demand-like actions in mixture costs and portions, so-called Keynesian provide shocks. We discover proof for this mechanism in a minority of nations in our Asia pattern, as properly for Europe and the USA, however that these outcomes are pushed by the COVID-19 occasion. Secondly, we use the granularity of the trade shocks to assemble country-level GDP shocks, pushed by idiosyncratic actions on the trade stage, to check cross nation progress spillovers for the three giant financial models in our pattern: China, Europe and the US.
