We document a negative and signi…cant relationship between domestic …nancial development and unemployment volatility in developing and emerging economies (DEMEs). However, there is no signi…cant relationship between these variables in advanced economies (AEs). A labor-search model with production heterogeneity, sectoral …nancial frictions, and inter…rm input credit can rationalize these di¤erential crosscountry results. Unemployment volatility is decreasing in …nancial development, but the quantitative relevance of this relationship is increasing in the extent to which input credit is prevalent in an economy. This insight is consistent with the fact that, empirically, input credit is much more prominent in DEMEs compared to AEs.
