DOES THE MARKET RECOGNIZE CORPORATE SOCIAL RESPONSIBILITY?

ABSTRACT

This article examines the impact of the Dow Jones Sustainability Index (DJSI) announcements that are prepared annually by RobecoSAM on the market value of Colombian firms. The analysis of 77 events and their impact on 13 firms for the 2009-2018 period found that DJSI-related events lead to insignificantly abnormal returns being generated for shareholders. The study suggests that this happens because Colombian companies do not widely disclose these types of event.

RESUMO

Este artigo examina o impacto dos anúncios do Índice Dow Jones de Sustentabilidade (DJSI), elaborado anualmente pela RobecoSAM, sobre o valor de mercado das empresas colombianas. Com base na análise de 77 eventos de 13 empresas colombianas no período 2009-2018, mostra-se que eventos relacionados ao DJSI geram retornos anormais insignificantes para os acionistas. O estudo sugere que isso se deve ao escasso esforço de divulgação desses tipos de evento por parte de empresas colombianas.

INTRODUCTION

Corporate social responsibility (CSR) can be understood as promoting social welfare beyond the company’s financial interests and law requirements (McWilliams & Siegel, 2001McWilliams, A., & Siegel, D. (2001). Corporate social responsibility: A theory of the firm perspective. The Academy of Management Review, 26(1), 117. doi: 10.2307/259398
https://doi.org/10.2307/259398...
). For CSR advocates, this behavior creates value by increasing the company’s probability of success based on long-term consolidation of social legitimacy (Porter & Kramer, 2006Porter, M. E., & Kramer, M. R. (December, 2006). Strategy & society: The link between competitive advantage and corporate social responsibility. Harvard Business Review, 84(12), 78-92.

). For the opponents, CSR distracts companies from their main responsibility: to generate value for shareholders (Baden, Harwood, & Woodward, 2009Baden, D. A., Harwood, I. A., & Woodward, D. G. (2009). The effect of buyer pressure on suppliers in SMEs to demonstrate CSR practices: An added incentive or counter productive?

Richter (Eds.), Corporate Ethics and Corporate Governance (pp. 173-178). Springer Berlin Heidelberg.). The debate between these two aspects is mainly fed by empirical studies in advanced economies with developed capital markets whose efficiency allows, in addition to measuring the impact of CSR efforts with a certain level of confidence, to assume an information flow between the company’s management and stakeholders. In emerging economies, low financial depth can limit information flow (González, Guzmán, Téllez, & Trujillo, 2021González, M., Guzmán, A., Téllez, D. F., & Trujillo, M. A. (2021).

https://doi.org/10.1016/j.econmod.2003.0...
) and decisions regarding CSR, which leads to a reduced effect on operating results. In this context, the effect of CSR depends on the company’s ability to send signals (Spence, 1973Spence, M. (1973). Job market signaling. The Quarterly Journal of Economics, 87(3), 355-374. doi: 10.2307/1882010

https://doi.org/10.1287/mnsc.1120.1630...
). Given the importance of disclosure in emerging markets (Montiel et al., 2012Montiel, I., Husted, B. W., & Christmann, P. (2012). Using private management standard certification to reduce information asymmetries in corrupt environments. Strategic Management Journal, 33(9), 1103-1113. doi: 10.1002/smj.1957

https://doi.org/10.1007/s10551-014-2404-...
), it is worth exploring whether this specific capital market recognizes the company’s CSR efforts and if companies disclose this information to obtain international recognition for their CSR activities and impact stakeholders.

This research addresses these issues offering (i) an analysis of the abnormal returns associated with the events of entry, continuation, and exit of the international Dow Jones Sustainability Index (DJSI) of all the companies participating in the Colombian capital market for the period 2009-2018, and (ii) the companies efforts to disclose and disseminate CSR efforts through general and specialized newspapers. Although the sample of events for the Colombian context is relatively small, Colombian firms are characterized by their early participation in the DJSI (compared to other companies from emerging markets) and the highest average rating in the index’s categories in which they participate (RobecoSAM, 2019RobecoSAM. (2019). SAM Corporate Sustainability Assessment Informe de progreso de América Latina 2019. Recuperado de https://www.spglobal.com/esg/csa/static/docs/Informe_de_progreso_de_America_Latina_2019.pdf
https://www.spglobal.com/esg/csa/static/...
). Because of these aspects, this group of organizations forms the longest and most diverse and representative series of observations for an emerging economy in Latin America. The analysis suggests that (i) the Colombian capital market ignores CSR announcements or does not acknowledge CSR efforts, and (ii) companies rarely disclose these efforts to inform stakeholders. The findings have strong theoretical and practical implications and corroborate the results of previous research. In addition, they stress the importance of strategies to disseminate information on CSR efforts.

From a theoretical perspective, our conclusion regarding the low impact of CSR announcements due to the underuse of communication channels validates the hypothesis by Barnett (2007)Barnett, M. L. (2007). Stakeholder influence capacity and the variability of financial returns to corporate social responsibility. Academy of Management Review, 32(3), 794-816. doi: 10.5465/amr.2007.25275520
https://doi.org/10.5465/amr.2007.2527552...
on the importance of influencing stakeholders. Our conclusion complements other studies that attempt to identify the mechanisms adopted to transform CSR in added value. For Servaes and Tamayo (2013)Servaes, H., & Tamayo, A. (2013). The impact of corporate social responsibility on firm value: The role of customer awareness. Management Science, 59(5), 1045-1061. doi: 10.1287/mnsc.1120.1630
https://doi.org/10.1287/mnsc.1120.1630...
, the mechanism is the intensity of advertising, whereas for Bardos, Ertugrul, and Gao (2020), it is the perception of the product, and for Li, Xin, Chen, and Ren (2017)Li, D., Xin, L., Chen, X., & Ren, S. (2017). Corporate social responsibility, media attention and firm value: Empirical research on Chinese manufacturing firms. Quality & Quantity, 51(4), 1563-1577. doi: 10.1007/s11135-016-0352-z
https://doi.org/10.1007/s11135-016-0352-...
, it is media attention. This study suggests that part of the mechanism is the opportunity to disseminate the events, and our event study methodology shows that companies do not inform stakeholders, which reduces CSR returns. The findings are consistent with research showing that weak or poorly focused disclosure strategies can reduce the effect on market value (Bardos et al., 2020Bardos, K. S., Ertugrul, M., & Gao, L. S. (2020). Corporate social responsibility, product market perception, and firm value. Journal of Corporate Finance, 62, 101588. doi: 10.1016/j.jcorpfin.2020.101588

https://doi.org/10.1016/S0165-4101(01)00...
). From a business view, the results show that the dissemination strategies are as important as the events themselves. Stakeholders, and the market in general, create value by incorporating information into prices, and the suboptimal use of a channel increases informational asymmetry to the detriment of the company’s value.

The article is organized into five sections, including this introduction. The next section presents a theoretical review of the debate on CSR, followed by the study’s methodology in the third section, which describes the procedure for calculating abnormal returns and data sources. Section four presents the results obtained from the statistical analysis of the events and the companies’ disclosure regarding CSR efforts, which support the arguments of the discussion and conclusion section. The fifth and final section reflects on the research limitations, suggests topics for future research, and exposes the study’s managerial implications.

CORPORATE SOCIAL RESPONSIBILITY (CSR) AND THE COMPANY’S VALUE

CSR was initially considered a costly activity that reduced profits and distracted management from its only commitment: to generate value for shareholders (Friedman, 1970Friedman, M. (1970). The social responsibility of business is to increase its profits. In W. C. Zimmerli, M. Holzinger, & K. Richter (Eds.), Corporate ethics and corporate governance (pp. 173-178). Berlin. Springer Berlin Heidelberg.), above other legal, ethical, or philanthropic responsibilities (Carroll, 1991Carroll, A. B. (1991). The pyramid of corporate social responsibility: Toward the moral management of organizational stakeholders. Business Horizons, 34(4), 39-48. doi: 10.1016/0007-6813(91)90005-G
https://doi.org/10.1016/0007-6813(91)900...
). With the development of stakeholder theory (Freeman, 1999Freeman, R. E. (1999). Response: Divergent stakeholder theory. The Academy of Management Review, 24(2), 233-236. doi: 10.2307/259078
https://doi.org/10.2307/259078...
), CSR gained importance by involving all stakeholders in companies’ performance. From this perspective, companies generate value for their shareholders and their employees, clients, creditors, and investors (Vargas, 2016Vargas, L. (2016). Corporate Social Responsibility and Financial Performance: GIC’s Share Prices Value Impact - Event Study. In Crowther, David & Seifi, Shahla (Eds.), Corporate Responsibility and Stakeholding (Vol. 10, pp. 165-177). Emerald Group Publishing Limited.). Therefore, CSR becomes a value-creating activity in a broader sense. The diversity of arguments that justify the strategic value of CSR ranges from organizational to contextual. For example, Cheng, Ioannou, and Serafeim (2014) argue that CSR activities can improve access to financing based on the commitment it incorporates. This commitment reduces the probability of opportunistic behaviors, increases transparency, reduces informational asymmetry between the company and investors, consequently relaxing capital restrictions and reducing the financing costs (El Ghoul, Guedhami, Kwok, & Mishra, 2011El Ghoul, S., Guedhami, O., Kwok, C. C. Y., & Mishra, D. R. (2011). Does corporate social responsibility affect the cost of capital? Journal of Banking & Finance, 35(9), 2388-2406. doi: 10.1016/j.jbankfin.2011.02.007
https://doi.org/10.1016/j.jbankfin.2011....
).

The impact at the organizational level is another of the arguments that favor the implementation of CSR activities. Behaving responsibly with stakeholders can reduce employee turnover costs, strengthen legitimacy in the community (Branco & Rodrigues, 2006Branco, M. C., & Rodrigues, L. L. (2006). Corporate social responsibility and resource-based perspectives. Journal of Business Ethics, 69(2), 111-132. doi: 10.1007/s10551-006-9071-z
https://doi.org/10.1007/s10551-006-9071-...
), and generate tax benefits that translate into better financial performance (Barnett & Salomon, 2006Barnett, M. L., & Salomon, R. M. (2006). Beyond dichotomy: The curvilinear relationship between social responsibility and financial performance. Strategic Management Journal, 27(11), 1101-1122. JSTOR. https://doi.org/10/eq8pve
https://doi.org/10/eq8pve...
). In other words, CSR initiatives involve costs that can be offset by reducing other company costs (McGuire, Sundgren, & Schneeweis, 1988McGuire, J. B., Sundgren, A., & Schneeweis, T. (1988). Corporate social responsibility and firm financial performance. Academy of Management Journal, 31(4), 854-872. doi: 10.5465/256342
https://doi.org/10.5465/256342...
) or by the benefits derived from improvements in corporate image, reputation, or corporate identity (Wang & Chen, 2017Wang, Y.-S., & Chen, Y.-J. (2017). Corporate social responsibility and financial performance: Event study cases. Journal of Economic Interaction and Coordination, 12(2), 193-219. doi: 10.1007/s11403-015-0161-9
https://doi.org/10.1007/s11403-015-0161-...
). For Kramer and Porter (2006)Kramer, M. R., & Porter, M. E. (2006). Estrategia y sociedad: El vínculo entre ventaja competitiva y responsabilidad social corporativa. Harvard Business Review, 84(12), 42-56. Recuperado de https://www.iarse.org/uploads/Porter_y_Kramer_Estrategia_y_Sociedad_HBR_dic_2006.pdf
https://www.iarse.org/uploads/Porter_y_K...
, CSR can become a source of opportunity, innovation, and competitive advantage by managing economic, social, and environmental challenges. In conclusion, CSR can become a source of social progress.

The empirical literature on the relationship between CSR and firms’ market value is extensive and supports significant and non-significant effects on the short or long-term share price. For example, Cellier and Chollet (2016)Cellier, A., & Chollet, P. (2016). The effects of social ratings on firm value. Research in International Business and Finance, 36, 656-683. doi: 10.1016/j.ribaf.2015.05.001

https://doi.org/10.5755/j01.ee.27.4.1337...
show that ranking ads produce strong short-term price reactions, while Robinson, Kleffner, and Bertels (2011) and Vargas (2016)Vargas, L. (2016). Corporate Social Responsibility and Financial Performance: GIC’s Share Prices Value Impact - Event Study. In Crowther, David & Seifi, Shahla (Eds.), Corporate Responsibility and Stakeholding (Vol. 10, pp. 165-177). Emerald Group Publishing Limited. argue that the reaction can become long-term if CSR consolidates the reputation and legitimacy of the company. The benefits of inclusion in a CSR index such as the DJSI are only obtained in the long term (Cho, Chung, & Young, 2019Cho, S. J., Chung, C. Y., & Young, J. (2019). Study on the relationship between CSR and financial performance. Sustainability, 11(2), 343. doi: 10.3390/su11020343
https://doi.org/10.3390/su11020343...
; Hawn, Chatterji, & Mitchell, 2018).

Some scholars argue that methodological differences in the studies or contextual aspects explain the variety of relations found between the DJSI and the firm’s value. For example, Orlitzky, Schmidt, and Rynes (2003)Orlitzky, M., Schmidt, F. L., & Rynes, S. L. (2003). Corporate social and financial performance: A meta-analysis. Organization Studies, 24(3), 403-441. doi: 10.1177/0170840603024003910
https://doi.org/10.1177/0170840603024003...
used a meta-analysis to show that most studies ignore the possible endogeneity due to inverse causality between CSR and financial performance and the lack of agreement between stakeholders’ objectives, leading to distortion of what could be a possible positive CSR effect.

For Pérez, López-Gutiérrez, Salmones, and San-Martín (2019), the positive effect, although low, depends on the coverage that the media dedicates to CSR, especially in the banking sector; while for Arya and Zhang (2009)Arya, B., & Zhang, G. (2009). Institutional reforms and investor reactions to CSR announcements: evidence from an emerging economy. Journal of Management Studies, 46(7), 1089-1112. doi: 10.1111/j.1467-6486.2009.00836.x
https://doi.org/10.1111/j.1467-6486.2009...
and Adamska and Dabrowski (2016)Adamska, A., & Dabrowski, T. (2016). Do investors appreciate information about corporate social responsibility? Evidence from the polish equity market. Engineering Economics, 27(4) 364-372. doi: 10.5755/j01.ee.27.4.13377
https://doi.org/10.5755/j01.ee.27.4.1337...
, the positive reactions of investors to the announcements of CSR initiatives depend on the institutional environment, especially in emerging economies. Durand, Paugam, and Stolowy (2019), who replicated the work of Hawn et al. (2018)Hawn, O., Chatterji, A. K., & Mitchell, W. (2018). Do investors actually value sustainability? New evidence from investor reactions to the Dow Jones Sustainability Index (DJSI). Strategic Management Journal, 39(4), 949-976. doi: 10.1002/smj.2752
https://doi.org/10.1002/smj.2752...
, found that market reactions to DJSI have a non-significant impact because the main advantage of CSR is to increase companies’ visibility and attract investors in the long term. This effect is identifiable only in the long term and makes short-term analysis irrelevant.

This research fuels the debate based on the evidence of entry, continuation, and exit of DJSI for the capital market in Colombia, an emerging market, and analyzes the companies’ disclosure of information when seeking to realize the value of its CSR efforts.

METHODOLOGY

This research adopts a conventional event study complemented with an analysis of the efforts of the firms to disseminate the CSR events to evaluate the prize or discount the Colombian market applies to the announcements of the Dow Jones Sustainability Index (DJSI). We analyzed abnormal returns for 77 events ‒13 entries, 61 continuations, and 3 exits of Colombian firms included at some point in the DJSI during the period from 2009-2018 (Table 1). The firms’ efforts to disseminate these events in general and specialized media channels in Colombia were analyzed.

Table 1
Company and events analyzed

This integrated approach contributed to justifying the study of the sample, compensating for its weaknesses considering the size. First, studying CSR efforts and events in Colombian companies contribute to understanding their impact on companies’ market value in emerging economies. To our knowledge, this is the first study that attempts to measure the value added by CSR in Colombia, and one of the few developed on emerging markets (Crisóstomo, Freire, & Vasconcellos, 2011Crisóstomo, V. L., Freire, F. de S., & Vasconcellos, F. C. de. (2011). Corporate social responsibility, firm value and financial performance in Brazil. Social Responsibility Journal, 7(2), 295-309. doi: 10.1108/17471111111141549
https://doi.org/10.1108/1747111111114154...
).

Second, as far as we know, this is the first study on abnormal returns examining the dissemination of the DJSI in printed communication media. Other studies used surveys (e.g., Bardos et al., 2020Bardos, K. S., Ertugrul, M., & Gao, L. S. (2020). Corporate social responsibility, product market perception, and firm value. Journal of Corporate Finance, 62, 101588. doi: 10.1016/j.jcorpfin.2020.101588
https://doi.org/10.1016/j.jcorpfin.2020....
) and indices generated by national or international agencies (e.g., Chang et al., 2019Chang, K., Shim, H., & Yi, T. D. (2019). Corporate social responsibility, media freedom, and firm value. Finance Research Letters, 30, 1-7. doi: 10.1016/j.frl.2019.03.019
https://doi.org/10.1016/j.frl.2019.03.01...
; e.g., Chung et al., 2018Chung, C. Y., Jung, S., & Young, J. (2018). Do CSR activities increase firm value? Evidence from the Korean market. Sustainability, 10(9), 3164. doi: 10.3390/su10093164
https://doi.org/10.3390/su10093164...
) to identify the importance of disseminating CSR events. Our methodology allows us to examine the use of this media to disseminate CSR events and examine their importance in the design of business strategy. Finally, the research data and analysis become a baseline for future research exploring series with a longer time scope or a greater variety of companies and sectors in Colombia and emerging markets.

The Colombian capital market counts 68 companies, and its main stock market index, COLCAP, includes 23 of them. The companies studied in this research represent 76.6% of the market capitalization, but only 13 are included in the index, and none of those included participates in the general Down Jones Global Index (DJI). They have only been included in the DJI for emerging markets (DJEMI). This indicates that while the companies in this research have a great capacity to affect the Colombian capital market, their importance is minimal in international capital markets.

For each of the 13 companies’ shares, the closing prices available on the Colombian Stock Exchange’s official website were extracted. The period analyzed for the shares prices differs among the companies due to some of the companies’ late entry or early exit to the Colombian stock market. Table 2 shows the periods and descriptive statistics of the series of returns examined.

Table 2
Company, period of analysis, and descriptive statistics on returns

Note: “Start date” and “end date” are the dates when the events were analyzed. The other columns are descriptive statistics on continuous daily returns observed between the start and end date.

Events and annual cycle of the DJSI

We observed the impact on the closing price related to three types of events: entry, continuation, and exit of the DJSI. Each event is published by RobecoSAM on the second Tuesday of September of each year, after an evaluation cycle that begins in March of each year and ends with the publication of results on the second Tuesday of September of the same year (Figure 1). RobecoSAM carries out the evaluation based on information provided by the companies through the corporate sustainability assessment (CSA) questionnaire. For this work, the publication of that list is the time point for each entry, continuation, or exit event.

Outreach media

We examined newspapers to observe the disclosure of the company’s CSR events in written communication media directed both to general and specialized audiences in Colombia. The terms “empresas colombianas en el DJSI” (Colombian companies in the DJSI), “Dow Jones Sustainability Index Colombia,” “DJSI Colombia,” and “Compañías colombianas DJSI” (Colombian companies DJSI) were searched in each of this communication media. We searched events published between September 2009 and December 2018. These events were tabulated according to the type of media and the frequency of publication. Other media such as radio or television were ignored because of the difficulty or high cost of accessing and verifying the data.

Abnormal returns

Abnormal returns are usually measured as the difference between the observed return and the expected return, based on an empirical model expected to reproduce the behavior of the financial asset (Brooks, 2014Brooks, C. (2014). Introductory econometrics for finance (3rd ed.). Cambridge: Cambridge University Press.). The financial asset is often calculated through a linear regression model on one or more market indices. Following this methodological trend, we evaluate the following indices as regressors: the COLCAP index of the Colombian Stock Exchange, the Dow Jones Industrial Emerging Market Index (DJEMI), the Dow Jones Emerging Markets Total Return Index (DJEMTRI) (in USD), the international price of oil, and the domestic currency price of the USD - which is the main currency in the Colombia international trade. From the R2 statistic, it was found that the COLCAP and DJEMI indices helped to capture the highest proportion of the variance in the returns. Thus, both indices were included in a two-factor model according to the following equation:

(1)Rit=αi+β1iDJEMIt+β2iCOLCAPt+eit

Where Rit corresponds to the logarithmic return of share i for day t and calculated based on the daily closing prices. The cofficients β1i and β2iare loads of the DJEMI and COLCAP factors, respectively, and eit is the error for each share i at time t. This model was estimated by ordinary least squares for each event at time t* and in the interval [t*-to-tp-5, t*-tp-5], using to=25 observations for the estimation, tp=5 days for the forecast window and a space of five days prior to the event that allowed reducing the possibility of inverse causality of the event on the coefficients of the model.

Once the factor model for each event had been estimated, the abnormal returns ARit were calculated in a window of [t*-5, t*+5] as:

(2)ARit=Rit-R^it
where R^it corresponds to the expected return of share i obtained from the model in (1). According to Corrado (2011)Corrado, C. J. (2011). Event studies: A methodology review. Accounting & Finance, 51(1), 207-234. doi: 10.1111/j.1467-629X.2010.00375.x
https://doi.org/10.1111/j.1467-629X.2010...
, the standard error of ARit can be estimated as:
(3)VAR(ARit)=σe2(1+1n+(ARit-ARit)2t=(n-10)-10(ARit-ARit)2)
where σe2 is the variance of the error of the regression eit (Greene, 2003). For sufficiently large degrees of freedom df = n-2, the ratio between an abnormal return and its standard error follows the Student’s t-distribution:
(4)t=ARitVAR(ARit)tn-2

For t values greater than a critical value t* given a type I error level of 5%, the null hypothesis of null abnormal returns (Ho: ARit=0) can be rejected with a 95% confidence level.

Because the t-Student statistic is sensitive to the assumption of normality of the returns, the analysis was complemented with a non-parametric alternative proposed by Corrado (2011)Corrado, C. J. (2011). Event studies: A methodology review. Accounting & Finance, 51(1), 207-234. doi: 10.1111/j.1467-629X.2010.00375.x
https://doi.org/10.1111/j.1467-629X.2010...
, who suggests comparing the abnormal return of an event with the sequence order of abnormal returns presented during the estimation period. In this comparison, the probability of having k values above the abnormal return on the date of the event is k/(n+1), where n is the number of observations used in the estimation period. If k/(n+1) is less than the critical significance value i.e., 5% for this investigation then the null hypothesis should be rejected (Corrado, 2011Corrado, C. J. (2011). Event studies: A methodology review. Accounting & Finance, 51(1), 207-234. doi: 10.1111/j.1467-629X.2010.00375.x
https://doi.org/10.1111/j.1467-629X.2010...
). The validity of this test does not depend on the probability distribution of the returns (Corrado, 2011Corrado, C. J. (2011). Event studies: A methodology review. Accounting & Finance, 51(1), 207-234. doi: 10.1111/j.1467-629X.2010.00375.x
https://doi.org/10.1111/j.1467-629X.2010...
). Thus, it adds robustness to the analysis in cases where the returns deviate significantly from a normal distribution.

Given that the analysis period includes crisis episodes such as the Subprime crisis in 2007 and the debt crisis in Europe, it is important to recognize that the greater volatility of the international capital markets could amplify the standard errors and challenge the task of identifying abnormal returns. To evaluate the impact on the errors’ distortion, we estimate the results by changing the width of the model’s estimation periods. This variation made it possible to examine the sensitivity of the results to the persistence of external shocks derived from episodes of international crisis while the introduction of the two indices made it possible to include the agents’ generalized perceptions in relation to emerging markets (DJEMI) and the local market (COLCAP).

RESULTS

Table 3 summarizes the results of the parametric and non-parametric analyses for the events. The table shows that significant abnormal returns are unevenly distributed both before and after the event date. At moment 0 i.e., the day the event was disclosed, only four stocks/continuation events presented significant abnormal returns: Grupo Argos (t = 1.45, p <0.05) in 2014, Éxito (t =-2.86, p <0.05) in 2015, ISA (t = 2.44, p <0.05) in 2018, and Isagen (t = 4.39, p <0.05) in 2015. The first company’s share is significant through the non-parametric procedure, while the other three are significant in both the parametric and non-parametric tests. In general terms, Table 3 shows a remarkable number of non-significant events that question the immediate effect of DJSI-related events on the market.

Table 3
Analysis of events of Colombian companies’ entry, continuation, and exit from DJSI

The numbers are values of t-statistics for the significant abnormal returns with the non-parametric test suggested in Corrado (2011)Corrado, C. J. (2011). Event studies: A methodology review. Accounting & Finance, 51(1), 207-234. doi: 10.1111/j.1467-629X.2010.00375.x
https://doi.org/10.1111/j.1467-629X.2010...
. Values higher than 2 were highlighted to indicate where the parametric t-test coincides with the non-parametric test. Other values were excluded to facilitate reading. Complete results can be found on the authors’ websites. Values indicated with (*) correspond to abnormal returns that coincide with dates on which news or reports about the respective event were found in national media.

In addition, Table 3 shows that, in the five days after the date of the events, the abnormal returns identified by both procedures are irregularly distributed across the dates, without a prevalence of positive or negative results, i.e., there is approximately the same ratio between positive and negative results. This pattern also occurs in the five days preceding the event. In general terms, the results in Table 3 suggest that it is not possible to identify a specific pattern of positive or negative effects related to the DJSI index entry, continuation, or exit events in the Colombian stock market.

One possible explanation for the observed low short-term impact of DJSI-related events is the mode and timing of the events. Low-scope dissemination channels, without a focus on a specific audience or with non-timely disclosure, can reduce the impact of an event. This explanation can be explored by observing Table 4, which presents a summary of the newspaper publications of the events according to the type of media: general or specialized media such as newspapers, magazines, and web pages aimed at an audience specialized in economics, finance, and business.

Table 4
Dissemination of events of the DJSI in media channels

According to Table 4, DJSI-related events are disclosed primarily through specialized media: the rate of use of specialized media is more than double that of general media. The media does not usually produce a generalized or automatic disclosure of events regarding the DJSI. The first line of results in Table 4 shows that 7 of the 13 companies that entered the index did not receive coverage through the media analyzed. The cause of this low repercussion could be the low interest or scope of the media publishing this information or poor initiatives by companies to take advantage of this opportunity to disseminate their CSR efforts.

Continuation events in the index seem to have received greater attention in the media analyzed, although the impact was not significant in the statistical tests. It is important to note that this type of event is disclosed as news regarding the DJSI and several companies in the same space or press release.

Regarding the exit event, the only company that received attention or dissemination through specialized media was Ecopetrol. Interest in this event seems to be associated with this company’s political and economic importance for the Government of Colombia. Ecopetrol generated, on average, 10% of the federal government’s revenues in the period 2011-2018, and in some periods, it reached 25% (Salcedo, 2020Rodríguez-Salcedo, C. G. (2020, marzo 9). El Presupuesto General de la Nación 2020 se calculó con un precio del Brent en US$67. Recuperado de https://www.larepublica.co/finanzas/esta-es-la-influencia-que-tienen-los-precios-del-petroleo-en-la-economia-colombiana-2974654
https://www.larepublica.co/finanzas/esta...
). Thus, this event can be considered of interest not only to investors but also to the general public.

The analysis of dates of the events in Table 3 and the dates the publications were released in newspapers show few coinciding dates. Specifically, only three events with significant abnormal returns coincide with the date of publication of the events in any of the national broadcast media. These events are marked with (*) in Table 3. The three abnormal returns occurred two days after the RobecoSAM report and only for events of recognition. However, two of them correspond to negative abnormal returns, while the other corresponds to a positive one. This finding suggests that the market does not seem to react positively or consistently to news about developments in the sustainability index. Also, it is consistent with a non-significant short-term impact of the inclusion of Colombian companies in the DJSI caused by poor dissemination of CSR efforts.

DISCUSSION AND CONCLUSIONS

This research analyzes the influence of Colombian companies’ entry, continuation, and exit of the DJSI in their stock prices, observing the period from 2009 to 2018. In addition, the study examines the efforts of these organizations to disseminate information regarding the DJSI-related events in the Colombian written communication media. The two fundamental results are: (i) the developments in the DJSI do not significantly affect the returns of the companies’ stocks, and (ii) the companies do not seem to make an effort to disseminate their information on CSR in the media.

As for the first result, our analysis shows that the investors’ reaction when the DJSI-related events are disclosed is not significantly different from what was expected or predicted through a two-factor model when the information on the DJEMI and COLCAP indices are disclosed. Therefore, such announcements do not generate abnormal returns. This finding corroborates theoretical arguments (Friedman, 1970Friedman, M. (1970). The Social Responsibility of Business Is to Increase Its Profits. In W. C. Zimmerli, M. Holzinger, & K. Richter (Eds.), Corporate Ethics and Corporate Governance (pp. 173-178). Springer Berlin Heidelberg.) and empirical analyses based on larger samples (e.g., Durand et al., 2019Durand, R., Paugam, L., & Stolowy, H. (2019). Do investors actually value sustainability indices? Replication, development, and new evidence on CSR visibility. Strategic Management Journal, 40(9), 1471-1490. doi: 10.1002/smj.3035
https://doi.org/10.1002/smj.3035...
; Hawn et al., 2018Hawn, O., Chatterji, A. K., & Mitchell, W. (2018). Do investors actually value sustainability? New evidence from investor reactions to the Dow Jones Sustainability Index (DJSI). Strategic Management Journal, 39(4), 949-976. doi: 10.1002/smj.2752
https://doi.org/10.1002/smj.2752...
). However, when this result is observed together with an analysis of the CSR dissemination efforts, it is possible to envision an alternative explanation for the phenomenon.

The conventional justification for the absence of abnormal returns is based on considerations regarding the CSR’s cost-benefits: social responsibility programs are activities that are too expensive in relation to the benefits (Sprinkle & Maines, 2010Sprinkle, G. B., & Maines, L. A. (2010). The benefits and costs of corporate social responsibility. Business Horizons, 53(5), 445-453. doi: 10.1016/j.bushor.2010.05.006
https://doi.org/10.1016/j.bushor.2010.05...
) they manage to incorporate into the price of the stock as a null net present value (NPV) - i.e., the events do not generate positive or negative abnormal returns.

that do not reject the weak efficiency of the Colombian market are compatible with this NPV incorporation in the price.

The contribution of this research lies in complementing the analysis by looking at the companies’ efforts to disseminate CSR information to stakeholders. Previous studies have shown that the absence of strategies to disseminate these announcements reduces the potential impact on stakeholders (Barnett, 2007Barnett, M. L. (2007). Stakeholder influence capacity and the variability of financial returns to corporate social responsibility. Academy of Management Review, 32(3), 794-816. doi: 10.5465/amr.2007.25275520

; Chung et al., 2018Chung, C. Y., Jung, S., & Young, J. (2018). Do CSR activities increase firm value? Evidence from the Korean market. Sustainability, 10(9), 3164. doi: 10.3390/su10093164
https://doi.org/10.3390/su10093164...
) or delays their influence in share prices (Searcy & Elkhawas, 2012Searcy, C., & Elkhawas, D. (2012). Corporate sustainability ratings: An investigation into how corporations use the Dow Jones Sustainability Index. Journal of Cleaner Production, 35, 79-92. doi: 10.1016/j.jclepro.2012.05.022
https://doi.org/10.1016/j.jclepro.2012.0...
). Our analysis of the Colombian firms’ efforts to disseminate the DJSI-related information demonstrates that they are not committed to this task. The events they have published in the general and specialized newspapers are short, in the middle of the newspapers, and include notes from many companies on the same page. In other words, the notes seem to correspond more to the routine dissemination work of the media vehicles than to particular initiatives of the companies aimed to impact the market. Based on this evidence, the non-significant impact of the events does not arise from the null value of the NPV caused by expensive CSR programs. It emerges from a communication problem that leads the market to ignore the news regarding DJSI events, thus underestimating the potential positive cash flows in the NPV.

The importance of the flow of information to stakeholders had already been noted by Servaes and Tamayo (2013)Servaes, H., & Tamayo, A. (2013). The impact of corporate social responsibility on firm value: The role of customer awareness. Management Science, 59(5), 1045-1061. doi: 10.1287/mnsc.1120.1630
https://doi.org/10.1287/mnsc.1120.1630...
, who measured it through the firms’ expenditures in advertising. This research confirms the literature and suggests a specific channel through which the information impacts the returns of the shares: the positive cash flows in the NPV, which is incorporated in the price. It is crucial to remember that empirical studies do not reject weak efficiency in the Colombian market, so the NPV is part of the price. The chain of argument, therefore, is: the ex-ante value of an announcement of the index is the expected value of the cash flow derived from the recognition (VE (DJSI) = p * CF, p <1). Once the event becomes a fact (p = 1), the value of the event in the NPV increases because of CF> VE (DJSI). However, if recognition is not properly disclosed to stakeholders, the market continues to value the effect of the index as a probability event less than one. The impact can be more far-reaching if more stakeholders are affected (Barnett, 2007Barnett, M. L. (2007). Stakeholder influence capacity and the variability of financial returns to corporate social responsibility. Academy of Management Review, 32(3), 794-816. doi: 10.5465/amr.2007.25275520
https://doi.org/10.5465/amr.2007.2527552...
).

Limitations and research opportunities

The results obtained in this study present limitations and are based on methodological decisions that force us to put the conclusions into perspective. For example, we mentioned in the methodology that the analysis was restricted to 13 of the 68 companies listed in the Colombian stock exchange. Although this subset represents 76.6% of the COLCAP index, the results cannot be extended to the entire market. Companies excluded from COLCAP usually smaller could be more sensitive to CSR events due to greater market concerns regarding their sustainability, generating higher share prices, such as that documented by Banz (1981)Banz, R. W. (1981). The relationship between return and market value of common stocks. Journal of Financial Economics, 9(1), 3-18. doi: 10.1016/0304-405X(81)90018-0
https://doi.org/10.1016/0304-405X(81)900...
in developed economies. The absence of small companies in the sample creates a selection bias not addressed here since it is beyond the scope. The creation of CSR indicators based on local information and multivariate methods such as factor analysis could offer the opportunity to elaborate more inclusive indices to study this size effect in an emerging market with low financial depth.

Regarding identifying events, the analysis assumes that most of the impact is manifested at the time of the event’s announcement. The negative or positive effects of CSR activities can be partially discounted at the time of their execution but weighted according to the probability of the company’s exclusion of the company from the index. Given that the company can respond with remedial or compensatory measures - for example, increasing investments in other aspects of the corporate sustainability assessment (CSA) - the investor tends to assign a small value to the probability of exclusion from the index, reducing the expected value of the company’s share and postponing until the moment of the announcement of the event, most of the impact. With this reasoning, most of the effect of CSR events should be concentrated in the announcements of the events increasing the validity of our arguments.

Another important limitation is the scope of the impact in terms of stakeholders. From stakeholder theory (Freeman, 1999Freeman, R. E. (1999). Response: Divergent stakeholder theory. The Academy of Management Review, 24(2), 233-236. doi: 10.2307/259078
https://doi.org/10.2307/259078...
), decisions about responsible behavior and sustainability responding to stakeholder expectations (Flammer, 2012Flammer, C. (2012). Corporate social responsibility and shareholder reaction: The environmental awareness of investors. Academy of Management Journal, 56(3), 758-781. doi: 10.5465/amj.2011.0744
https://doi.org/10.5465/amj.2011.0744...
). Given that this research studies the reaction in only one of these stakeholders - shareholders - the variation in share prices may not capture the full impact of CSR efforts (Barnett, 2007Barnett, M. L. (2007). Stakeholder influence capacity and the variability of financial returns to corporate social responsibility. Academy of Management Review, 32(3), 794-816. doi: 10.5465/amr.2007.25275520

https://doi.org/10.3390/su10093164...
), or be delayed by its incorporation in the price (Searcy & Elkhawas, 2012Searcy, C., & Elkhawas, D. (2012). Corporate sustainability ratings: An investigation into how corporations use the Dow Jones Sustainability Index. Journal of Cleaner Production, 35, 79-92. doi: 10.1016/j.jclepro.2012.05.022
https://doi.org/10.1016/j.jclepro.2012.0...
).

Managerial implications

Given that the companies’ CSR efforts required a positive NPV to be implemented, and the study of events shows the absence of positive abnormal returns, it seems natural to conclude that the information on the DJSI announcements is not effectively communicated to the market. In short, companies appear to miss out on the implicit and explicit benefits that arise from such announcements. From this chain of arguments emerges our main recommendation: The announcements related to the DJSI constitute a valuable opportunity for companies to use all media tools to transmit information to the market about their CSR efforts and make the positive return that these efforts improve their organizations. This recommendation is not without caveats: there must be a correspondence between CSR actions and dissemination strategies. Dishonest or superficial CSR actions are known as green-or social-washing (Chen & Chang, 2013Chen, Y.-S., & Chang, C.-H. (2013). Greenwash and green trust: The mediation effects of green consumer confusion and green perceived risk. Journal of Business Ethics, 114(3), 489-500. doi: 10.1007/s10551-012-1360-0

); concealment of personal interests of managers in CSR activities (agency problems); Marketing practices designed to manipulate customer perception or appease critics; and the slowdown of the company’s operations derived from the organizational subsystem in charge of CSR activities can induce adverse perceptions in stakeholders and negative effects on the firms’ value, seeking correspondence should be part of the managerial task in the company.
