The "Collapse in Quality" Hypothesis

Article Citation

Levchenko, Andrei A., Logan T. Lewis, and Linda L. Tesar. 2011. "The "Collapse in Quality" Hypothesis." American Economic Review, 101(3): 293-97.

DOI: 10.1257/aer.101.3.293


This paper evaluates the hypothesis that during the 2008-2009 collapse in international trade, imports of higher quality goods experienced larger reductions compared to low-quality imports, using data on US imports disaggregated by HS-10 product category and source country. We find little, if any, robust econometric evidence in support of this hypothesis.
