The objective of this research is to study the impact of Corporate Social Responsibility (CSR) on financial performance. The trend of CSR addresses a major challenge in providing a broader representation of the business environment, understood not simply in its economic and financial but also social, human and ecological through an operationalization and verification of the theoretical model proposed in a sample of Tunisian firms, evidenced by a questionnaire sent to 30 companies Tunisian drawn. The results are the lack of link between CSR and financial performance measured by the accounting ROA, while there is a positive if financial performance is measured by ROE.

L'objectif de cette recherche est d'étudier l'impact de la Responsabilité Sociétale de l'Entreprise (RSE) sur la performance financière. La RSE répond à un enjeu majeur, en proposant une représentation élargie de l'environnement des firmes, entendu non seulement dans ses dimensions économiques et financières, mais aussi sociales, humaines et écologiques. A travers, une opérationnalisation et une vérification du modèle théorique proposé, au niveau d'un échantillon d'entreprises tunisiennes, matérialisé, par un questionnaire adressé à 30 entreprises tunisiennes tiré au sort. Les résultats obtenus relèvent l'absence de lien entre la RSE et la performance financière mesurée par l'indicateur comptable ROA, alors qu'il existe un lien positif si la performance financière est mesurée par l'ROE.

In the 1850s, the role of the company was seen as a purely economic, and bounded to the maximization of profit for shareholders. In this regard, such an approach is consistent with a classical view of the firm where management essentially concerns managers and shareholders (Friedman, 1970). Further, the company was faced increased pressure from its stakeholders (Freeman, 1984). In this regard; it should take into account the effects of its activities in the communities where it operates. This brings her back to reconsider its relations with its stakeholders and to reconcile the often conflicting objectives of various interest groups. The idea of social responsibility of business now (CSR) responds to this challenge by providing a broader representation of the business environment, understood not simply in its economic and financial but also social, human and ecological.
Any company that wants to ensure its sustainability, an imperative for financial performance, but also should not ignore or largely ignore the societal benefit that is to say, to engage in a societal approach. The objective of this research is twofold , first to study the impact of CSR on financial performance. Second in a more explicit, we wish to study in the target companies in our survey, the degree of perception of the concept of social responsibility through five dimensions namely: economic, legal, ethical, discretionary, and environmental. In this part, our problem is as follows;
What is the impact of social responsibility of corporate financial performance?
SOCIETAL RESPONSIBILITY OF THE COMPANY (CSR): TOWARDS THE EMERGENCE OF A NEW CONCEPT
"Being responsible is to ensure their actions and their consequences and to accept accountability. But when this term is applied to the company, it is a concept that can be understood in different ways. Nowadays, the definition and delimitation of the concept of social responsibility still the subject of controversy and conceptual differences. So, social responsibility has been the subject of increased attention by many organizations of diverse nature, the European and global institutions, professional associations and business networks, Its emergence is born with Bowen (1953) who scored in the first initiative "CSR refers to the requirement for businessmen to carry out the policies, decisions and follow the guidelines spreading objectives and values that are considered desirable in our society". Subsequently, MC Guire (1963) argues in his work that "the idea of social responsibility implies that the firm has not only economic or legal obligations but also has responsibilities to society that go beyond these obligations ".
Then, Davis (1973) emphasizes that "CSR refers to the consideration by the business issues that go beyond its economic obligations and the technical equal and close to the answers that gives these companies problems. This means that CSR begins where law ends. For Carroll (1979) 'CSR integrates all economic expectations, legal, ethical and philanthropic society may have in respect of a company at a time. " While Jones (1980) stresses "the idea that companies, by then the statutory or contractual obligation to have a societal actors. Similarly, Wood (1991) anchors his discussion on "the meaning of the liability can be seen that through the interplay of three principles: legitimacy, public responsibility and distinction of three levels of institutional analysis, organizational and individual". In reality, these definitions are generally content to highlight the discretionary nature of CSR, highlighting the fact that it recognized the dimensions beyond the purely economic or legal activity of the company. What brought Carroll (1979) distinguish four categories of CSR:
- The economic responsibility
- The legal liability,
- Responsibility Ethics
- Responsibility discretion.
Approaches to CSR measures
Measuring CSR is a necessary condition for knowledge of their own social responsibility and thus to control environmental and social impacts. Assessing the social and environmental performance, the establishment of a steering system for the performance and accountability on these external dimensions imply the existence of metrics to assess the quality of management of the business related non-financial. In fact, the existence of these metrics is also of particular importance to other stakeholders that ethical investors who require such information to select the best performing companies on the main criteria the quality of resource management Human and respect for human rights. This leads companies to establish a legal and socio-technical infrastructure to make measurable CSR stakeholders. In theoretical terms, the extent of CSR faces similar problems to those identified to define the concept of CSR: the multiplicity of approaches and dimensions of this complex concept, difficult to report objectively its components more subjective often linked to an assessment based on criteria related to ethics or a social context.
Measuring CSR in the academic literature
Among the different methods of measurement of CSR that have been used, we can distinguish five categories:
- Measures of speech, such as content analysis of annual reports, which are to be based on remarks made by companies to assess their CSR, for example by counting the number of lines or words dedicated to themes CSR in the annual report of a company;
- Indicators of pollution provided by some agencies to assess the pollution of businesses, such as the Toxic Release Inventory "in the U.S., or for example measurements of the diffusion of CO2 by businesses;
- Measures of attitudes and values aimed at assessing the sensitivity of members of the organization (eg managers, employees) to the various dimensions of CSR and are generally administered in the form of a questionnaire;
- Measures of reputation, such as the indicator of reputation developed by Markowitz in the 1970s in the American magazine Fortune, which includes criteria related to CSR that are assessed by a panel of industry experts to which operates within the enterprise in question;
- The behavioral measures or audit, developed by the agencies that specialize in the assessment of social behavior and environmental responsibility, such as the U.S. KLD, EIRIS in Britain or in France Vigeo.
FINANCIAL PERFORMANCE: DEFINITION
Performance is tried to rely on market efficiency that ensures the best allocation of resources and rejects any notion of corporate responsibility other than making profit for its shareholders. As a design performance based on an external view (the current shareholders and potential), often linked to the stock exchange during the action of the company. The performance measures are thus based on data from financial statements. The control and management are geared towards the minimization of costs and return on investment. It is a large building which includes questions on the financial performance within the organization. For a financial indicator, the financial performance of the organization is measured by its financial validity, such as accessibility to different sources of funding or its profitability compared to its investments, its assets or its equity.
MEASUREMENT OF FINANCIAL PERFORMANCE
According to empirical studies, accounting measures provide most of the time positive correlations between CSR and financial performance. (Cochran and Wood, 1994; Waddock and Graves, 1997; Preston and O 'Bannon, 1997; Stanwick and Stanwick, 1998; Balabanis, Hugh and Jonathan, 1998, Moore, 2001; Rufetal, 2001). In addition, these measures from the accounts have the advantage of providing a more relevant measure of economic performance of the company and predict a more reliable the possible link between CSR and financial performance. On the other hand, the stock market measures have the advantage of being less prone to managerial manipulation. Especially since they represent scores of investors on the business' ability to generate economic benefits (Mc Guire et al, 1988). However, these variables are evaluated specific investor and does not allow to reveal the economic reality of the business (Ullmann, 1985), the results that emerge from studies using measures such as stock market are mixed, Markovitz, (1972) found a positive relationship, Vance (1975) proves otherwise, and Buchotz Alexander (1978) found a weak correlation or no. Griffin and Mahon (1997) stress that results from market-related measures are mostly negative and called for greater use of accounting measures. To better understand the financial performance and provide a more comprehensive or less of the latter, further research incorporating both measures at a time (Mc Guire, et al, 1988; Balabanis, Hugh and Jonathan, 1998, Moore, 2001 ; Seifert; Maurras and Barktkus, 2003, 2004).
SOCIETAL RESPONSIBILITY AND FINANCIAL PERFORMANCE
CSR and financial performance: theoretical approaches
The existence of a relationship between CSR and financial performance
The theoretical approaches to corporate social responsibility are essentially based on the current contract philosophers and sociological neo-institutionalism. They particularly questioned the compatibility between market logic and the goal of maximum profit that underpin the economic rationale of the business and societal concerns such as sustainable development, intergenerational equity, the general interest which are purposes prior to appearing foreign or contrary to the entrepreneurial logic. In other words, the exercise of social responsibility of business is it an impossible synthesis between the collective demands long-term expectations and short-term private? The theoretical basis is between two opposite poles: on one side, the neoclassical theories, based on market efficiency, reject any idea of social responsibility of business other than making profit for its shareholders (Friedman, 1970). On the other, theories that mobilize a teleological principle and argue that there is a moral responsibility of policy makers towards future generations and a large number of societal problems. However, the only approach "moralistic-ethical" is not sufficient to illuminate the strategic behavior of firms in the societal area because it does not understand the motivations of corporate behavior. In this approach, stakeholders influence policy decisions of leaders and they are accountable to them about how they took into account their expectations.
The stakeholder theory
From the 1980s, the theory of stakeholders (Stakeholders theory) is gradually accepted as a framework to further specify the groups vis-à-vis what the enterprise is (or should exercise) its societal responsibilities. The work of Freeman (1984) popularized this theory by proposing to define as "stakeholder" all persons or groups who are likely to affect and / or be affected by the conduct of the strategy of undertaking. The theory of stakeholder theory is now the most frequently mobilized both by researchers as actors in the business. She entered the company at the heart of a set of relationships with partners who are not only shareholders (Shareholders), but players interested in or affected by the activities and business decisions. The stakeholder theory is not exempt from a normative vision and ethics but it seeks to integrate economic goals: it states that cooperation contracts establish trust between the firm and its stakeholders and provides a competitive advantage the company. One might wonder whether the inclusion of stakeholder expectations is not rather the result of traditional rules of management that the outcome of a deliberative process of integrating moral principles.
Despite its omnipresence in all the literature on corporate social responsibility, this theory remains ambiguous about its theoretical basis and presents a number of limitations. On the one hand, it is part of a relational representation of the organization based on fair contracts that involve conflicts of interest may be resolved by ensuring a maximization of the interests of each group. On the other hand, it would be unrealistic to consider a comprehensive consideration of all potential stakeholders. The rationality of leaders is necessarily limited by the urgency of the problems, pressures and information systems available to them that they decided to put in place. A first theoretical approach suggests that the company is more successful socially; it is more efficient economically and financially. Instead, the company will be more economically efficient and less it will be socially. Finally, beyond these two extreme views, it is possible to consider the assumptions of positive and negative synergy that cross the different conceptual foundations. With these assumptions also added a generic assumption of neutrality of interactions: Gond, 2001) and assuming a more complex relationship.
CSR and financial performance: Many theoretical explanations
The theoretical explanations to clarify the nature of the relationship between societal and financial performance are numerous. They can be organized into three distinct categories: explanations postulating the existence of linear relationships between these two constructs, explanations suggesting no link between the two constructs, and finally explanations assume the existence of nonlinear relationships between these two variables.
The models suggest a positive link between CSR and performance
Two theoretical models support the idea of a positive impact of CSR on financial performance (Social Impact Hypothesis) and the assumption of funds available as excess resources available to discretionary managers or "Organizational Slack (Available Fund Hypothesis). According to the hypothesis of "positive social impact, companies with a high level of CSR demonstrate their ability to master the implicit costs and negative externalities of the organization and report to stakeholders and the quality of their management. The theory of stakeholders (Stakeholders theory) that establishes the hypothesis of the influence of social practices, has created a vast literature on the interaction between CSR and firm performance (Freeman, 1984, Cornell and Shapiro, 1987; Ullmann, 1985, Clarkson 1995, Donaldson and Preston, 1995): Satisfaction with the business objectives of stakeholders promotes the improvement of economic and financial performance (Freeman, 1984).
The second model, that of "Organizational Slack" addresses the link between social performance and economic performance by proposing the idea that this is not the social responsibility that is the condition for obtaining a high level financial performance but, instead, the level of financial performance which allows the company to engage in socially responsible actions. Mc Guire et al, (1988) reported that financial performance could improve the level of social performance and their work has been partially confirmed those by Preston et al, (1991). The profitability of the business differential is then a condition of social behavior; Kraft and Hadges (1990) have shown that excess resources and the attitude of managers towards society strongly influence the level of responsibility social enterprises.
The models suggest a negative relationship between CSR and financial performance
Unlike the two previous models, others say that companies realize the best social performance are also those with the worst economic performance and vice versa in this spirit, a negative relationship between societal performance and financial performance dominates.
The literature suggests two models that assume a negative relationship between CSR and performance, distinguished by the nature of causality assumed. The first model "Trade-Off Hypothesis" or assumptions arbitration assumes that the inclusion of corporate social responsibility involves additional financial costs resulting therefore a competitive disadvantage (Friedman, 1962, 1970). In this perspective, any move away from socially responsible leaders of their goal of maximizing profits (Aupperle, Carroll and Hatzfeld, 1985). Drucker (1984, p.58) states that "making a profit is fundamentally incompatible with the social responsibility of business
The models suggest a positive or negative synergy
The typology developed by Preston and O'Bannon (1997) suggests two hypotheses that are based on different theoretical approaches outlined above. Indeed, in the context of a comprehensive model explaining it is possible to envisage a virtuous circle (positive synergy): a high level of social performance leads to improved financial performance that provides the opportunity to reinvest in social actions responsible (Waddock and Graves, 1997). In contrast, a low level of societal performance led to a decline in financial performance limits, therefore, socially responsible investment (negative synergy).
The models suggest a missing link
The conceptual contributions of Mc Williams and Siegel (2001) lead Gond (2001) to complete the typology of Preston and O 'Bannon (1997) by formulating the hypothesis of no link between the two dimensions. Indeed, Mc Williams and Siegel (2001) propose a model of supply and demand for social responsibility that helps explain the lack of consensus results obtained by empirical academic studies. According to them, there is a supply and demand for social responsibility, in a standard micro, who led each of them to invest socially to meet the demand of stakeholders. Market equilibrium cancels costs and profits generated by successively supply of "social responsibility". This approach leads to a hypothesis of neutrality of interactions between social performance and financial performance.
The models suggest a more complex relationship
The results obtained by Bowman and Haire (1975) led Moore (2001) also refine the typology of Preston and O'Bannon (1997) and the hypothesis of positive relationship between more complex two-dimensional. Indeed, Bowman and Haire (1975) but also, more recently, Barnett and Salomon (2003) showed a non-linear U-shaped inverted between social performance and financial performance, indicating an optimum level beyond which socially responsible investment longer improves financial performance. The multiplicity of theoretical hypotheses advanced to explain the nature of interactions between CSR and financial performance has led to develop empirical tests to define the conditions of validity of the various mechanisms invoked.
CSR and financial performance: empirical approaches
Clarification of the economic impact of CSR has always been a major concern in the field of study on the relationship between business and society. It is therefore not surprising that empirical work on this issue have been very numerous, there were in 2007 more than 160 empirical studies on the subject. This work focused on the nature of interactions between the firms' ability to achieve a high level of CSR and financial performance by studying the interactions between on the one hand, social performance (or societal) Company (CSR) and, secondly, its financial performance (FP). These interactions have been studied mainly through two levels of analysis we will present successively:
Many publications over the last twenty years have highlighted the link between social responsibility and financial performance of the company. But these studies show conflicting results do not establish clearly the existence of a positive or negative relationship between social responsibility and financial firms (Preston and O'Bannon, 1997; Griffin and Mahon, 1997; Mac Williams and Siegel , 2001, Margolis and Walsh, 2002). "The lack of theoretical foundation and conceptual studies, lack of uniformity in evaluation of social responsibility and financial and methodological shortcomings found explain the poor results obtained. Studies most recent research (Griffin and Mahon, 1997; Roman Hayibor and Agle, 1999, Margolis and Walsh, 2003) found a slight advantage for the detection of positive links between societal performance and financial performance . The synthesis of the literature identifies 122 studies published between 1971 and 2001 with an accelerating pace of recently published (35 studies between 1997 and 2001) and far (2007) on more than 160 empirical studies on this subject, but also this research were sometimes biased in the direction of the illumination of a positive relationship. For example, the 122 education fifty and claim a positive association between social responsibility and financial performance twenty get mixed results, twenty seven indicate no ties and seven observed a negative relationship.
The hypothesis of impact-social "Social Impact Hypothesis"
According to (Freeman 1984, Donaldson and Preston, 1995), stakeholder theory has explained the origin of the favorable influence social behavior on financial performance. Indeed, CSR is an indicator of the ability of business to effectively meet the demands of various stakeholders. This has consequently regained their confidence and thus improve profitability (Balabanis, Hugh and Jonathan, 1998). Waddock and Graves (1997) speak of "Good Management Theory" that there is a high correlation between good management practice and CSR, simply because an improvement in social activity entails a special relationship with "Key Stakeholders Groups "(Freeman, 1984), implying more performance. In addition, a review of empirical literature confirms a positive relationship between the two components (Mc Guire et al, 1988; Waddock and Graves, 1997; Preston and O'Bannon, 1997; Verschoor, 1998, Stanwick and Stanwick, 1998; Mc Williams and Siegel, 2000, Moore 2001, Ruf et al, 2001, Orlitsky, 2001; Kohers and Simpson, 2002). Allouche and Laroche (2005) identified 82 research, 75 of them have found a positive link, while Margolis and Walsh (2003) who counted 54 out of 127 studies confirming the positive relationship. Hence our first hypothesis H1: Social responsibility has a positive impact on financial performance.
The "Trade-Off Hypothesis"
This hypothesis refers to the classical theory of Friedman (1962, 1970) that CSR is an investment that increases costs and takes place at the expense of financial performance. For example a decision to invest in equipment acquisition environmentally friendly while other competitors do not, can generate a competitive disadvantage. Hence the reduction in profitability which may cause discontent among shareholders. This finding was also confirmed by Aupperle et al, (1985), the authors conclude that social activities such as donation to charity, environmental protection and community development dissipate more resources and generate additional costs, which disadvantages the company against its competitors less engaged in social actions.
Searches return the negative relationship to abnormalities in particular methodological tools to measure financial performance. The negative association is due to the use of market variables as a measure of financial performance (Griffin and Mahon, 1997). In reality, the number of studies that lead to a negative relationship is very small, Margolis and Walsh (2003) identify 127 studies dealing with the subject in question, and they found that only 8 of them expect a negative correlation between the two dimensions. of where our second hypothesis H2: The social responsibility has a negative impact on financial performance.
The lack of connection between the two dimensions
Some authors suggest that CSR and financial performance are both built entirely separate. Ullmann (1995) emphasizes that the link from a pure coincidence. The correlation is generated, according to the author, by intervening variables that occur in an unpredictable manner and that link the two constructs. Meanwhile, Waddock and Graves (1997) show that the methodological problems in operationalizing CSR tend to obscure the link. A multitude of empirical studies have provided no link between the two dimensions (Aupperle et al, 1985; Fogler and Nutt, 1975; Abbot and Monsen, 1979, Freedman and Jaggi, 1986; O'Neil, Mark Saunders and Carthey 1989; Seifert, Maris and Barkus, 2004, Graves and Waddock, 1999). Others state that the link is weak or nonexistent (Alexander and Bchholz 1978, Cochran and Wood, 1984; Krauz and Pava, 1996; Berman et al, 1999; Balabanis, Hugh and Jonathan, 1998, Seifert and Morris Barktkus , 2003). Griffin and Mahon (1997), Balaban, Hugh and Jonathan (1998) found that the results are inconclusive: the variables selected do not distinguish between successful firms and inefficient firms. In this context, our third hypothesis H3: There is no link between social responsibility and financial performance.
CSR and financial performance: The effect of control variables
Research has shown that the relationship between CSR and financial performance is not absolute, it must take into account the weight of the elements of each company (Ullmann, 1985; Waddock and Graves, 1997) and are likely to moderate the relationship between the two constructs. These characteristics are operationalized as control variables.
The effect risk
The risk is variable, with several studies in different contexts have shown that it controls the relationship between the two dimensions. The argument assumes the risk that companies have a low risk to commit advantage in social activities, and vice versa. Companies with low risk have a stable performance model, and therefore, this situation seems very conducive to investment in social activities (Roberts, 1992). Aupperle et al, (1985) postulate that firms more socially responsible are identified as being better managed and risks are minimal. This finding is especially approved by the study of Mc Guire et al, (1988); O'Neil, Mark Saunders and Carthey (1989), Waddock and Graves (1997), Graves and Waddock (1999). In contrast, Aupperle et al, (1985) found a correlation, positive correlation between CSR and risk accounting, and negative but not significant between CSR and market risk.
The effect size
The argument for the size stipulated that organizations undertake major advantage in social actions; small organizations do not give importance to social activity (Waddock and Graves, 1997). Burke et al, (1986) argue that companies, as and as they grow, give more attention to external factors and better meet the demands of stakeholders, Stanwick and Stanwick (1998) found that size, measured by the volume of sales and total assets is positively related to CSR.
Mc Guire et al (1988) find a positive but not significant between CSR and the size measured by total assets.
The effect sector
The sector as designed in the literature is a moderating effect of CSR and PF relationship, eg the extent of the consideration of environmental responsibility by a chemical company is not the same a financial institution. A plurality of researchers took into account the control variable as in include: Waddock and Graves, 1997, Griffin and Mahon, 1997, Graves and Waddock, 1999; Balabanis, Hugh and Jonathan, 1998, McWilliams and Siegel 2000, Moore 2001, Ruf et al, 2001; Seifer, Morris and Barktkus, 2003.2004.
METHODOLOGY OF RESEARCH
The objective of empirical research is to empirically test our research hypotheses and the theoretical model proposed. In order to test the validity of our assumptions on a sample drawn from all Tunisian companies, we proceeded by two steps the first is to measure the perception of Tunisian companies to the concept of CSR and then study the impact of this latest financial performance. Through our research, we chose the method of direct interview, and for several reasons, we conduct a field investigation, by adopting the technique of direct investigation on the basis of a questionnaire. The survey covered a sample of 30 Tunisian companies selected from different sectors.
The scale of measurement of CSR predictor
For measurement of CSR, we will adopt that developed by Maignan et al (1999), which forms part of the work on measuring social performance. This scale operationalizes the concept of social performance by measuring the dimensions of the construct. In fact, two major scales have been developed in this perspective: The oldest is that of Aupperle, Carroll and Hatfield (1985) measuring the orientation of managers towards social responsibility, the latest and most complete is that of organizational citizenship Maignan et al. (1999), reused by Maignan and Ferrell (2001).
These two instruments take over the traditional classification in four types of social responsibilities of Carroll (1979): economic, legal, ethical and discretionary or philanthropic organizations that are a reflection of society see the company actively engaged in its local environment and / or global defense of social causes and public interest.
Regarding the scale of Aupperle et al (1985), it is intended to measure only the views of leaders on the relative importance of each of the four dimensions of social responsibility of business.
While the scale of Maignan et al. (1999) is designed to gather perceptions of the social performance of the business stakeholders throughout the company (Maignan and Ferrell, 2001).
Indeed, the scale was constructed from academic studies describing activities commonly accepted as citizens by the three main stakeholders ie employees, customers, stakeholders public.
These authors manage this work, mainly to executives (Maignan et al 1999, Maignan and Ferrell, 2001) to have completed the questionnaire as relevant as the leaders and general information about the company cutting.
Hence, our questionnaire has five dimensions are those of Carroll (1979), added an environmental dimension whose items are inspired by the Global Compact (1999).
This choice is argued by the importance it attaches to the environment today, and the pressures that companies face to reflect the impact of its activities on the environment in which it operates, it is relevant namely the impact of the inclusion of the natural environment on the financial performance of Tunisian firms.
The measure of financial performance: variable to explain
The various empirical studies testing the relationship between CSR and financial performance have opted for the latter measure, accounting measures, or measures for stock market listed companies or both sets. In our case we use accounting measures that our sample consists of companies listed and unlisted. The measures derived from accounting are:
The performance of assets "ROA"
Means various researchers who have opted for this measure are: Aupperle et al. 1985 Mc Guire et al. 1988; O'Neil Sunders and Mc Carthey 1989, Waddock and Graves, 1997, Griffin and Mahon, 1997; Preston and O'Bannon, 1997, Graves and Waddock, 1999; Seifert, Morris and Barktkus 2003, Simpson and Kohers, 2002, Berman et al, 1999.
ROA = Net income / Total assets
The returns on equity "ROE"
Bowman and Haire, 1975; Pava and Krausz, 1996; Waddock and Graves, 1997, Griffin and Mahon, 1997; Seifert, Morris and Barktkus 2003; Verschoor, 1998; Balabanis, Hught and Jonathan 1998, Ruf et al, 2001; Preston and O'Bannon, 1997. The financial data used are those from 2004, 2005, 2006 and 2007.
ROE = Net income / Equity
We took into account three variables that can affect controls that are either CSR or financial performance, which are the effect size, effect and risk effect industry.
- The size is measured by the logarithm of total assets (Seifert, Morris and Barktkus, 2004; Kohers and Simpson, 2002, Johnson and Greening 1999).
- Risk is measured by the debt ratio as suggested by Waddock and Graves (1997) and Ullman (1985).
- The sector is taken as a moderator variable (Waddock and Graves, 1997, Griffin and Mahon, 1997, Graves and Waddock, 1999, Balaban, Hugh and Jonathan, 1998, Mc Williams and Siegle, 2000; Moore, 2001; Ruf et al, 2001; Seifer, Morris and Barktkus, 2003, 2004).
Ratios of debt = Total Debt / Equity
Check the measurement model of CSR
We present in what follows the procedures we use to verify the reliability and validity of the scale of measurement of CSR. The analysis was performed using the software for data analysis SPSS13.0. Various steps must be taken to ensure that the analysis is properly conducted. We begin by submitting the scale factor analysis. In terms of "characteristics", we have selected the "initial structure" in the "Statistical Area" and "weightings", "significance levels" and index KMO and Bartlett's test in the "correlation matrix". The KMO test used to quantify the degree of correlation between variables and the appropriateness of factor analysis. This indicator is between 0 and 1. The test of sphericity of Bartlett (1954) tests the hypothesis of no correlation in the correlation matrix. This test must be significant that the data are factorization (p <0, 05). As a result, we used principal component analysis as extraction method with orthogonal rotation (Varimax).
Through the results obtained, it is necessary that each variable must be correlated to a single axis. This happens when the difference between the saturation on the main axis and saturation on any axis is greater than 0.3. Otherwise, it means that the variable is correlated with both axes, we must eliminate it and re-factor analysis. After determining the number of items presented in each scale, we calculate the Cronbach alpha. The reliability coefficient to estimate the degree of internal consistency of the isolated structure. The value of alpha which is generally considered acceptable in basic research, is 0.7, but this value can be lowered to 0.6 in exploratory research (Hair et al, 1998). Measuring CSR consists of four dimensions (economic, legal, ethical and discretionary) developed by Carroll (1979) and psychometrically validated by Maignan et al (1999). Our extension is the addition of the environmental dimension whose items are inspired by the Global Compact in 1999.
In what follows, we analyze the results of factor analysis of each dimension of our variable CSR. Subsequently, we present the Cronbach's alpha which is used to verify the reliability of items.
On the first economic dimension it includes 4 items. The KMO index (0.693), the significance of Bartlett (p = 0.002), shows that the original data matrix is factorized. Factor analysis shows that four items are related to the first factor (maximize profit), this factor is 52.285% of the total variance and a value greater than 1 is to 2.091. The correlations of items with factor chosen are all above 0.5 (with the exception of item 4 that a correlation equal to 0.489). The Cronbach's alpha releases worth 0.639, so the scale used to measure the economic dimension is reliable. The second dimension is shown legal KMO index of 0.610, the significance of Bartlett is equal to 0.002. Two successive factor analysis was performed where we removed the first item because it has the lowest correlation (0.437) compared other items. The Cronbach's alpha is equal to 0.509 we can admit that for our sample is small. The third ethical dimension consists of five items. The KMO index (0.681) and significance of Bartlett is equal to 0,002 are satisfactory. Factor analysis shows that five items are related to the first factor, which represents 46.571% of the total variance, and it is above 1 (2.329). The Cronbach's alpha is 0.7 which shows the reliability of the scale measuring this dimension.
The fourth dimension is discretionary, it consists of 4 items. Two iterations were performed where it was eliminated the third item. KMO index is 0.578 and the significance of Bartlett shows a value (p = 0.000), releasing an acceptable result. The Cronbach's alpha showed a value of 0.793, which means that this scale is reliable. Finally the environmental dimension is measured by 4 items. The KMO index (0.762) and significance of Bartlett (p = 0.000), showing that the original data matrix is factorized. Two factor analysis were conducted in which we removed the first item. Regarding the reliability of this measurement scale items selected show good internal consistency. Indeed, Cronbach's alpha has a value of 0.854. The first factor obtained is the environmental dimension. The value of Cronbach's alpha was 0.854. This factor includes items relating to undertake a great responsibility to the environment, promote the development and dissemination of technologies that respect the environment and finally the provision of a program to reduce energy consumption and d water.
This result seems logical, since after the ecological disasters suffered by our planet, there is great pressure from various stakeholders to ensure that businesses take into account the natural environment in their business processes. Tunisian companies are aware of the need to protect the environment where they operate. The second factor is the dimension discretion for Cronbach's alpha of 0.793, indicating the potential role of enterprises in Tunisian society. There is no doubt therefore that the company as an organization located in the heart of social change, expands its environment to take account of social, human and other. The third factor, it is the ethical dimension to a Cronbach's alpha of 0.7 this position may be explained by the fact that the Tunisian companies want to appear first as trustworthy to its stakeholders, then initiated a climate of shared trust, especially after the financial crises that affected everyone.
Secondly, provide accurate and complete, this may pose a strategic asset to attract more investors. In fourth place comes the economic dimension, which leads us to relativize the neoclassical theory which states that the only responsibility of business is to maximize profit (Friedman1962, 1970). The last dimension concerns the legal dimension. This can be explained by the fact that the law is a requirement that all companies must comply, so the law does not present a liability that the company must ensure that voluntarily such as ethics or the protection of the environment. In the case of a dismissal or recruitment company is required to respect the labor code. All these results support the idea of a social responsibility to the company expands the business environment in understanding its economic dimensions and legal but also social, human and ecological.
In what follows we will try to present the regression results using the method of panel data, each variable of financial performance (ROA, ROE) on five dimensions of CSR.
The impact of CSR on financial performance measured by ROA
Before presenting the results we first define the regression function as follows:
ROAit = α0 + α1 DECOit + α2 DLEGit + α3 DETHit + α4 DDISCRit + α5 DENVit + ξit
- ROA: Return on assets
- DECO: Economic Dimension
- DLEG: Legal Size
- DETH: The Ethical Dimension
- DDISCR: Size discretionary
- Denv: Environmental dimension
- α0, α1, α3, α4, α5: The regression coefficients
- ξ it: The error term
- T: time
- I: number of companies [1, 30]
The results of the study of the impact of social responsibility on financial performance measured by ROA reveals no relationship between these two variables (see table below). Indeed, the low value of R ² (3%) and R ² adjusted absolute (5%) show a linear fit small, so a weak explanation of financial performance based on social responsibility.The overall significance of the model is examined by the test card that has a value greater than 0.005, which proves that the model is not globally significant. Examination of the estimators associated with each of the five dimensions of CSR shows no significance, except the economic dimension that has a coefficient (?) negative and statistically significant. The analysis therefore shows a neutral effect of CSR on PF. Several studies have shown no link between the two constructs (Aupperle et al, 1985; O'NEIL, Saunder and Mc Carthey 1989, Griffin and Mahon, 1997; Seifert, Morris and Barktkus 2003, Mc Williams and Siegle 2000).
We also noticed that F Ficher displays a value of 3.9% <5%, indicating that the model is globally significant. Despite this improvement, the relationship remains neutral. With the introduction of variable risk (F = 0.039) and industry (F = 0.46) we noticed that the model is generally not significant, which means that the risk variables and industry are not of effect on the relationship between CSR and financial performance. We therefore conclude that the introduction of control variables (size, risk, industry) the relationship between social responsibility and financial performance remains neutral. In this regard, and according to the study by Ullmann (1985), which indicates that there are many variables that can intervene and moderate the relationship between social responsibility and financial performance? The author further argues that the exception may moderate social responsibility financial performance, there may be random, and the measurement problem of social responsibility can mask the possible link between the two constructs.
In this context, other authors have argued that the relationship between social responsibility and financial performance was so complex and indirect that it is not possible to postulate the existence of a stable relationship between two variables (Gond and Igalent, 2008).
By providing more social responsibility, companies are increasing their costs but can also benefit from an extra demand for their goods which incorporate responsibility sociétale.les consumers are ready for them to bear an additional cost to afford property more responsible. At equilibrium model, the profit opportunities associated with the supply of social responsibility are exhausted and the company positioning companies for social responsibility does not affect their profitability, the relationship is neutral "(Gond and Igalent, 2008).
The impact of CSR on financial performance measured by ROE
The regression function is defined as follows:
ROE it= α0 + α1 DECOit + α2 DLEGit + α3 DETHit + α4 DDISCRit + α5 DENVit + ξit
- ROA: Return on assets
- DECO: Economic Dimension
- DLEG: Legal Size
- DETH: The Ethical Dimension
- DDISCR: Size discretionary
- Denv: Environmental dimension
- α0, α1, α3, α4, α5: The regression coefficients
- ξ it: The error term
- T: time
- I: number of companies [1, 30]
Unlike ROA, social responsibility of the company said better financial performance is conducted in this case by the ROE. Indeed, R ² is around 38%, that is to say the variation is explained ROE become relevant in explaining the financial performance namely the dimension discretion of 38% by societal actions the variable component of social responsibility have no effect on the financial performance measured by ROE at 95% confidence. But at 10% risk of certain variables
The probability of Ficher displays a value (p = 0.000) indicating that the model is globally significant. With the moderation control variables we have noticed no improvement. Indeed decreases R ² and has a value of 27% with variable size by 33% with varying risk and 27% with the variable area. We can therefore conclude the lack of moderating effect of control variables on this relationship. We can report that with the introduction of variable size and risk, we have noticed that the dimension discretion has a positive effect on financial performance measured by ROE. This can be explained by the fact that businesses large sizes and less risky Debt undertake more in philanthropy to gain in terms of image.
It is also pertinent to conclude that the environmental dimension in both cases measuring the financial performance produced a negative effect. This result can be explained by the fact that the investment environment is very expensive, which negatively affects financial performance.
In conclusion we can say that the social responsibility of business has a positive impact on financial performance measured by ROE. Indeed, the inclusion of stakeholders will result in improved economic performance, that is to say the most successful enterprises on non-financial criteria, benefit from a stakeholders' behavior more favorably than their competitors and thus have higher financial performance. The positive effect of social responsibility is tolerated by the research of Waddock and Graves (1997), Preston and O'Bannon (1997); Balabanis, and Jonathan Haught (1998), Rufetal (2001); Vershoor (1998).
Throughout this work, we tried to study the impact of social responsibility of the company's financial performance on a sample of 30 Tunisian companies. To do this, we first administered a questionnaire to take the measure of social responsibility. We concluded that the average trend of the respondents were directed towards the environmental dimension, then the dimension discretion, then the ethical dimension, economic dimension and finally the legal dimension. Once one has specified the factors of social responsibility we then studied the impact of that on the financial performance indicators measured by ROA and ROE. The results show the absence of a link between social responsibility and financial performance measured by ROA, while the relationship is positive when the latter is measured by ROE. We can also conclude that the control variables (size, risk, and sector) do not moderate the relationship between social responsibility and financial performance. Hence, we can conclude that social responsibility has a positive impact on financial performance, if the latter is measured by the ROE, but we note that there is no relationship between the two built if financial performance is measured by ROA. We can also conclude that the control variables (size, risk, and sector) do not moderate the relationship between social responsibility and financial performance.
