The Trade-Comovement Puzzle
Standard international transmission mechanism of productivity shocks predicts a weak endogenous linkage between trade and business cycle synchronization: a problem known as the trade-comovement puzzle. We provide the foundational analysis of the puzzle, pointing to three natural candidate resolutions: i) financial market frictions; ii) Greenwood–Hercowitz–Huffman preferences; and iii) dynamic trade elasticity that is low in the short run but high in the long run. We show the effects of each of these candidate resolutions analytically and evaluate them quantitatively. We find that, while ...

Long-Run Trade Elasticity and the Trade-Comovement Puzzle
We show that the trade-comovement puzzle - theory's failure to account for the positive relation between trade and business cycle synchronization - is intimately related to its counterfactual implication that short- and long-run trade elasticities are equal. Based on this insight, we show that modeling the disconnect between the low short- and the high long-run trade elasticity in consistency with the data is promising in resolving the puzzle. In a broader context, our findings are relevant for analyzing business cycle transmission in a large class of models and caution against the use of ...
