The objective of this Ph.D. dissertation is to have a better comprehension of the bankruptcy event for firms that are operating in France. We focus mainly on firms considered to be among the best-performing ones, i.e., exporting firms and innovating firms, that have a higher proportion of default than the general proportion. In the first chapter, we focus on the exporting firms’ sunk costs linked to the foreign markets to evaluate if it acts as an exit barrier or raises their likelihood of going bankrupt. In the second chapter, we estimate the impact of business expenditures on R&D on firms’ survival likelihood to assess how the risk firms take to innovate affects the likelihood of cessation of payment. Finally, in the last chapter, we evaluate how the exit of defaulting firms contributes to the French productivity growth compared to other firm exits. To do so, we use multiple databases to obtain all the information needed across the dissertation (BODACC for information on bankrupt firms, FICUS-FARE for accountancy variables, DADS for labor variables, among others), and other databases that are more specific for the first and second chapters: the custom data on import and exports and the innovation survey. To tackle several methodology issues, such as unobserved variables, truncation bias, and unobserved individual heterogeneity, various methods are used, particularly panel data methodologies applied to non-linear models. We find that sunk costs are not a barrier to exit since it limits the liquid assets available in case of financial difficulties. We also find that R&D activities require a minimum amount of investment to raise the survival likelihood. Finally, we find that the exit of defaulting firms contributes positively and significantly to productivity growth.
