This paper analyses in what extent innovation contributes to the productivity premium of exporters. We start by performing non parametric tests on TFP distributions on different groups of firms characterized by their export and innovation behavior. We show that the TFP distributions of exporters and innovators stochastically dominate those of...

Is corporate financial structure a determinant of non-price competitiveness in export markets? In this paper we provide a positive answer to this question by finding that among illiquid exporters leverage is negatively correlated with the quality of their exported goods. This result is obtained on a sample including over 120,000 export flows of...
