This paper analyzes optimal paths in a one-sector growth model when the technology is not convex. In such a case, we prove that optimal paths converge to the upper steady state iff the initial wealth is above a critical level. Then, we first show that, thanks to debt and/or R&D, the poverty trap may be avoided. Second, we introduce a distortion: corruption that mostly has dramatic consequences on growth, but may have a beneficial effect if it is not high and if it improves productivity (incentive effect).
This documents aims at bridging productivity measurement and weak sustainability in a specific data envelopment analysis framework that allows for negative output. In this framework countries use two inputs: capital and labour and seeks to maximize output and adjusted net saving. The indicator suggested dwell on the new growth theory with multiple equilibria. Adjustment net saving is seen as a sustainability indicator and then the productivity indicator computed can be understood as a sustainability productivity index.Ce document a pour objectif de rapprocher la mesure de la productivité et la durabilité du développement à travers un cadre spécifique de la méthode d'enveloppement des données. Dans cette analyse un pays utilise deux facteurs de production : le capital et le travail et cherche à maximiser la production ainsi que l'épargne nette ajustée. Ce nouvel indicateur se place dans le cadre des nouvelles théories de la croissance ou des équilibres multiples sont possibles. L'épargne nette ajustée est vue comme un indicateur de durabilité et l'indicateur de productivité calculé peut être considéré comme un indicateur de productivité durable
