We use a sample of 148 events related to corporate social responsibility (CSR) to assess the impact of CSR on corporate financial performance.

One main conclusion of this study is that socially responsible investment is not an excuse for passive management. There is still room for timing and stock picking within the socially responsible universe of stocks.

This document reviews the concept of green investing and reports the results of a European survey of investment management professionals.

The use of a period of various lengths shows that results can vary greatly from one length to another.

L’objectif de ce rapport a été, dans un premier temps, de trancher le débat méthodologique sur le choix de la valeur du taux d’actualisation des concessionnaires autoroutiers dans le cadre de leur actuelle privatisation. De nombreuses polémiques sont nées en référence à un rapport du Commissariat général au Plan de février 2005, qui conclut que les projets d’investissements publics doivent être réalisés sur 17/23 la base d’un taux d’actualisation de 4%.
