Abstract
This thesis examines the impact of socially responsible investment on the risk and performance of portfolios. It is based on four studies, including three empirical studies.The first study proposes an inventory and a critical analysis of the portfolios' CSR risks. It indicates that CSR risks assessed in different ways by the actors still exist within the portfolios and evolve with the institutional context. Their level may be low or high depending on the CSR practices of the companies in which the resources are invested. The second study deals with the comparative analysis of the financial risk of SRI funds and conventional funds. On a sample of funds distributed in France over the period 2002-2012, our results show that SRI funds may have a higher level of diversification than matched conventional matched regardless of market conditions. These are SRI funds invested in the Eurozone and globally. However, regardless of market conditions, SRI funds invested in the Eurozone, Europe and France have a greater systematic risk than their traditional counterparts, contrary to SRI global funds. The third study analyzes the financial risk of portfolios built according to companies’ level of ESG performance over the period 2002-2014. These portfolios cover the Eurozone and the U.S. firms. Our analysis shows that the U.S. portfolios which over-perform on the aggregate ESG criteria or individually on the three ESG criteria have a lower financial risk than those that underperform on these dimensions. For the same types of portfolios, the Eurozone exhibit a lower specific risk. The results on the systematic risk are influenced by the industry-specific effects for the U.S. portfolios and the country-specific effects for the Eurozone portfolios. The fourth study examines the financial performance persistence of SRI and conventional funds. It shows through non-parametric tests that there is no performance persistence for both SRI and conventional funds.Cette thèse examine l’impact de l’investissement socialement responsable sur le risque et la performance des portefeuilles. Elle s’articule autour de quatre études, dont trois études empiriques. La première étude propose un état des lieux et une analyse critique des risques RSE des portefeuilles. Elle indique que les risques RSE évalués de diverses manières selon les acteurs existent toujours au sein des portefeuilles et évoluent en fonction du contexte institutionnel. Leur niveau peut être plus au moins élevé selon les pratiques RSE des entreprises dans lesquelles les capitaux sont placés. La deuxième étude porte sur l’analyse comparative du risque financier des fonds ISR et des fonds conventionnels. Sur un échantillon de fonds commercialisés en France sur la période 2002-2012, nos résultats montrent que les fonds ISR peuvent avoir un niveau de diversification plus élevé que les fonds conventionnels appariés, quelles que soient les conditions de marché. Il s’agit des fonds ISR investis dans la zone euro et à l’international. Cependant, les fonds ISR investis dans la zone euro, en Europe et en France ont un risque systématique plus important que celui de leurs homologues classiques contrairement aux fonds ISR investis à l’international. La troisième étude analyse le risque financier des portefeuilles construits selon le niveau de performance ESG des entreprises sur la période2002-2014. Ces portefeuilles portent sur des entreprises de la zone euro, mais aussi sur des entreprises américaines. Nos analyses montrent que les portefeuilles américains qui sur-performent globalement ou individuellement sur les trois critères ESG ont un risque financier plus faible que ceux qui sous-performent sur ces dimensions. Pour les mêmes types de portefeuilles, la zone euro affiche un risque spécifique plus faible. Les résultats sur le risque systématique sont influencés par les effets relatifs au secteur d’activité pour les portefeuilles américains et par ceux relatifs au pays pour les portefeuilles de la zone euro. La quatrième étude examine la persistance de la performance financière des fonds ISR et des fonds conventionnels. Elle indique à travers les tests non-paramétriques qu’il n’existe pas de persistance de la performance pour les fonds ISR et les fonds conventionnels.

Social Protection in Low Income Countries and Fragile Situations : Challenges and Future DirectionsOvadiya, Mirey; Zampaglione, Giuseppe; Das, Maitreyi; Andrews, Colin; Elder, John (World Bank, Washington, DC, 2013-05-28)Demand for social protection is growing in low income countries and fragile situations. In recent years, the success of social protection (SP) interventions in middle income countries (MICs) like Brazil and Mexico, along with the series of food, fuel, and financial crises, has prompted policymakers in low income countries (LICs) and fragile situations (FSs) to examine the possibility of introducing such programs in their own countries. Flagship programs in countries as diverse as Ethiopia, India, Pakistan, and Rwanda have shown the adaptability of social protection interventions to the LIC context. Yet, despite growing levels of support for these initiatives, many challenges remain. In LICs and FSs, governments are confronted with a nexus of mutually reinforcing deficits that increase the need for SP programs and simultaneously reduce their ability to successfully respond. Governments face hard choices about the type, affordability, and sustainability of SP interventions. The paper reviews how these factors affect SP programs in these countries and identifies ways to address the deficits. It supports the establishment of resilient SP systems to address specific needs and vulnerabilities and to respond flexibly to both slow and sudden onset crises. To achieve this, both innovation and pragmatism are required in three strategic areas: (i) building the basic blocks of SP systems (e.g., targeting, payments, and monitoring and evaluation); (ii) ensuring financial sustainability; and (iii) promoting good governance and transparency. These issues suggest the possibility of a different trajectory in the development of social protection in LICs than in MICs. The implications for World Bank support include the need to focus on increasing knowledge and operational effectiveness of SP programs, fostering institutional links between multiple SP programs, and using community capacity and technological innovations to overcome bottlenecks in operations.

Managing Risk, Promoting GrowthWorld Bank (World Bank, Washington, DC, 2016-02-08)A growing body of evidence demonstrates
 that individuals and households experience a range of
 positive outcomes from social protection. Social protection
 increases productivity and growth. Countries can realize
 significant benefits by creating an integrated social
 protection system. Social protection is affordable in
 low-income countries despite tight budgets. While overall
 spending on social protection in Africa remains low by
 international standards, experience suggests that social
 protection programs can achieve national coverage at the
 cost of only 1 to 2 percent of gross domestic product (GDP).
 While this is only a portion of the financing required to
 operate a social protection system, it draws attention to
 what countries can achieve in the short-term. Indeed, one
 way in which existing social protection spending can be made
 significantly more efficient would be by reallocating
 existing financing for inefficient subsidies and ad hoc
 emergency food aid to predictable safety nets. At the same
 time, pursuing reforms to social security systems will
 ensure their fiscal sustainability, while expanding
 coverage. Notably, the costs of not protecting poor families
 are very high, are borne disproportionately by women and
 children, and undermine the productivity of future
 generations. The Strategy will be implemented by leveraging
 partnerships, knowledge, and the World Bank's financing
 instruments. The World Bank will continue to invest in
 analytical work to fill knowledge gaps and promote an
 evidence-based dialogue for social protection systems in
 Africa and further innovation. It will work with governments
 to build country-owned national social protection systems
 with the aim of reducing fragmentation in the sector. The
 Bank also will pay particular attention to institutional
 development and capacity building by using its lending to
 increase the coverage of successful social protection
 interventions. Throughout this work, the Bank will work in
 coordination with governments, development partners, the
 private sector, academics, civil society, and beneficiaries.

ISSPThe International Social Survey Programme (ISSP) is a continuing annual programme of cross-national collaboration on surveys covering topics important for social science research. It brings together pre-existing national social science projects and co-ordinates research goals, thereby adding a cross-national, cross-cultural perspective to the individual, national studies. Formed in 1983, the group develops topical modules dealing with important areas of social science as supplements to regular national surveys. Every survey includes questions about general attitudes toward various social issues such as the legal system, sex, and the economy. Special topics have included the environment, the role of government, social inequality, social support, family and gender issues, work orientation, the impact of religious background, behaviour, and beliefs on social and political preferences, and national identity. Participating countries vary for each topical module. The merging of the data into a cross-national dataset is performed by the Zentralarchiv fuer Empirische Sozialforschung, University of Cologne. A compact disc (CD-ROM) (archived under SN 3479) containing data and documentation for ISSP surveys carried out 1985-1996, 1998, 2000 and 2002 is available from the UKDA. Main Topics:The CD-ROM contains the complete collection of data and documentation of the International Social Survey Programme (ISSP) between 1985 and 1996, 1998, 2000. In these years, the ISSP conducted twelve different Social Science Surveys in up to 30 countries. The collection comprises the following titles: 1985 - Role of Government I (6 countries) (ZA 1490,UKDA 2448) 1986 - Social Networks and Support Systems (7 countries) (ZA 1620, UKDA 2560) 1987 - Social Inequality I (10 countries) (ZA 1680,UKDA 2702) 1988 - Family and Changing Sex Roles I (8 countries) (ZA 1700, UKDA 2744) 1989 - Work Orientations I (10 countries) (ZA 1840, UKDA 2864) 1990 - Role of Government II (9 countries) (ZA 1950, UKDA 2956) 1991 - Religion (16 countries) (ZA 2150, UKDA 3062) 1992 - Social Inequality II (17 countries) (ZA 2310, UKDA 3498) 1993 - Environment (20 countries) (ZA 2450, UKDA 3473) 1994 - Family and Changing Gender Roles II (22 countries) (ZA 2620, UKDA 3584) 1995 - National Identity (22 countries) (ZA 2880, UKDA 3809) 1996 - Role of Government III (23 countries) (ZA 2900, UKDA 4480) 1998 - Religion 11 (30 countries) (ZA 3190, UKDA 4482) 2000 - Environment 2000 (34 countries) (ZA 3440, UKDA 4827) 2002 - Family and Changing Gender Roles III (34 countries) (ZA 3880, UKDA 5018) Additionally, the 1985 and 1990 surveys, Role of the Government I and II, have been cumulated for those countries and those variables which have been included in both surveys: 1985/1990 - Role of the Government I/II (5 countries) (ZA 2240, UKDA 3499). All of the above are also available as separate datasets. The data for 1997, 1999 and 2001 are available separately on dedicated CD ROMs.
