Estimating Trade Elasticities: Demand Composition and the Trade Collapse of 2008-09
This paper introduces a new methodology for the estimation of demand trade elasticities based on an import intensity-adjusted measure of aggregate demand, with the foundation of a stylized theoretical model. We compute the import intensity of demand components by using the OECD Input-Output tables. We argue that the composition of demand plays a key role in trade dynamics because of the large movements in the most import-intensive categories of expenditure (especially investment, but also exports). We provide evidence in favor of these mechanisms for a panel of 18 OECD countries, paying particular attention to the 2008-09 Great Trade Collapse.
