For more than 15 years, the investment community and the academic community have written extensively on socially responsible investment (SRI). Despite the abundance of SRI thought, the adoption of SRI practices among institutional investors is a comparative rarity. This paper endeavours to achieve two goals. First, by integrating the practitioner and academic literature on the topic, the paper attempts to identify the many impediments to SRI in Europe from an institutional investor's perspective. Second, the paper proposes a unitary framework to conceptually organize the impediments to SRI by using insights from different relevant research perspectives: behavioural .nance, organizational behaviour, institutional theory, economic sociology, management science and .nance. The paper concludes by presenting the main shortcomings within both the academic and the practitioner literature on SRI and by providing conceptual and methodological recommendations for further research.
