This paper provides new firm-level evidence of the impact of financial frictions on international trade. First, by drawing on a unique instrument to capture financial frictions at firm level, we address concerns about endogenous measures of firms' financial constraints. Second, we test empirically the role of distance and long trading time in reinforcing the negative effect of financial frictions on firms' exports. We use detailed customs and balance sheet data combined with a unique dataset on payment incidents to conduct this empirical analysis. We find that financial frictions significantly reduce firm's export sales. Our estimations show a significant effect of distance and trading time in reinforcing the negative effect of financial frictions on export sales.
