Summary: | The failure of trade economists to
anticipate the extreme drop in trade post Lehman Brothers
bankruptcy suggests that the behavior of trade in
exceptional circumstances may still be poorly understood.
This paper explores whether uncertainty shocks have
explanatory power for movements in trade. VAR estimations on
United States data suggest that domestic uncertainty is a
strong predictor of movements in imports, but has little
effect on exports. Guided by these results, the paper
estimates a bilateral model with focus on the impact of
importer uncertainty on foreign suppliers. It finds that
there is a strong negative relationship between uncertainty
and trade and that this relationship is non-linear.
Uncertainty matters most when its levels are exceptionally
high. The paper does not find evidence of learning from past
turmoils, suggesting that prior experience with major
uncertainty shocks does not reduce the effect on trade. In
line with the expectations, the negative effect of
uncertainty shocks on trade is higher for trade
relationships more intensive in durable goods. Surprisingly,
however, the effect of durability is non-linear. Supply
chain considerations or the possibility that the
relationships with the highest durability lead to important
compositional effects may have a bearing on the results. The
results are robust to excluding the post Lehman shock,
suggesting that the trade response during the 2008-2009
crisis has been similar to past uncertainty events. |
