Estimating mixture models still raises numerous questions, both theoretical and empirical. However, this class of model appears quite powerful for a parcimonious modelization of ill-behaved distribution, as it is the case with loans rate vis-à-vis the private sector collected by the Banque de...

We uncover technological standardization as a microeconomic mechanism which is vital for the implementation of new technologies, in particular general purpose technologies. The interdependencies of these technologies require common rules (“standardization”) to ensure compatibility. Using...

Our study aims at assessing the actual importance of the two main channels usually contemplated in the literature through which upstream sector anticompetitive regulations may impact productivity growth: business investments in R&D and in ICT. We thus precisely try to estimate what are the...

ICT productive performances have slowed down since the beginning of the 2000s, before the current crisis. This diagnosis could be due, at least partly, to some statistical mis-measurements of ICT improvements. Nevertheless, improvements in ICT performances will probably be positively impacted,...

Numerous economic studies have highlighted that ICT investment expenditure appears to be greater in the field of services, and above all in certain activities such as financial services and wholesale trade, than in industry. This analysis examines whether the investment data compiled by national...

Studies of firm-level data have shown that there is a huge dispersion of productivity across firms even when industries are narrowly defined. So there is a significant opportunity for the least productive firms to catch up to the most productive. The formers’ convergence could therefore...

La contribution des technologies de l'information et de la communication (TIC) à la croissance du PIB et de la productivité du travail serait en France de l'ordre de 0,2 à 0,3 % par an sur l'ensemble de la période 1980-2000. Elle aurait connu une forte augmentation sur la seconde moitié des...

In response to the very large number of quantitative indicators that have been put forward to measure the level of systemic risk since the start of the subprime crisis, the paper surveys the different indicators available in the economic and financial literature. It distinguishes between (i)...

The paper describes the methods used by the French Banking Supervision Authority (ACP) to run stress tests for the corporate credit portfolio, through credit migration matrices (or transition matrices). This approach is currently used for “top-down” stress tests exercises. Developed for...
