A standard assumption in the empirical literature is that exchange rate pass‐through is both linear and symmetric. This study tests these assumptions for export and import prices in the G7 economies. It focuses on non‐linearities in the reaction of profit margins to exchange rate movements, which may arise from the presence of price rigidities and switching costs. Nonlinearities are characterized by augmenting a standard linear model with polynomial functions of the exchange rate and with interactive dummy variables. The results suggest that nonlinearities and especially asymmetries cannot be ignored, although their magnitude varies noticeably across countries.
This paper introduces a new methodology for the estimation of income trade elasticities based on an import intensity-adjusted measure of aggregate demand. It provides an empirical illustration of this new approach for a panel of 18 OECD countries, paying particular attention to the 2008-09 Great Trade Collapse, which standard empirical trade models fail to account for. In this paper, we argue that the composition of demand plays a key role in the collapse of trade during crises because of a relatively bigger fall in the most import-intensive categories of expenditure (especially investment, but also private consumption), which has a large downward impact on the quantity of imports from the rest of the world. In addition, the fragmentation of production implies high import content of exports and, in turn, strongly synchronized trade ‡uctuations across countries. We provide evidence in favor of these factors based on the analysis of the new OECD input-output tables and building on a stylized theoretical model. Importantly, we show that our new intensityweighted measure of demand outperforms alternative measures, during crises but also in normal times, providing import elasticities of demand that are much less volatile across the cycle.
