1. Introduction
During the recent decade, various studies have looked at the link of CS and FP among large and listed companies. However, the worldwide trend to be greener and pay more attention to the sustainability of society has spread not only in the latter firm segment, but also among the unlisted micro-, small- and medium-sized enterprises (SMEs). Most of the empirical studies have focused on Western countries, while studies about CS activities and practices in Eastern Europe have remained in a considerable minority (
Horváth et al. 2017a).
Relying on the theoretical fragmentation and research mostly on the example of certain firm types in specific environments, this study aims to provide empirical proof of how different sustainability initiatives are linked with firm failure risk. For that purpose, we apply a sample of unlisted firms of all sizes from the population of Estonian firms, for which information about environmental and social sustainability initiatives has been collected from their websites based on a known taxonomy. Firm failure risk is portrayed with a universal robust model, which enables predicting financial resilience with an acceptably high accuracy. The results provide an answer to the theoretical postulate by
Amankwah-Amoah and Syllias (
2020) in the short run context and oppose the mainstream empirical findings on the interconnection of FP and CS.
3. Study Design
As unlisted firms, especially SMEs, usually do not provide sustainability information in their annual reports (
Lääts et al. 2017), a different information source has to be used to collect the relevant data. The two main available options include primary data by means of questionnaires and secondary data by means of different disclosures. This study implemented the latter option by considering the published information on firms’ websites. Sustainability disclosures in the web are a usual source of information in the relevant literature (e.g.,
Lodhia 2010;
Moure 2019). Still, it should be acknowledged that while questionnaires can always be subject to a response bias, websites can be subject to a publishing bias, i.e., relevant information might have been left undisclosed. The latter should be differentiated from the disclosure bias (
Fischer and Verrechia 2004), as that concerns annual reports, which unlike websites still follow certain international or local guidelines. It is reasonable to assume that the publishing bias is distributed randomly, i.e., it is not inherent to some specific type of firms.
This paper is based on a sample of firms from Estonia, which was obtained during research conducted in early 2020 and fully reported in
Pajur and Saaroja (
2020). Therefore, the sample’s formation particulars and collection of sustainability information described herewith is a summary of the detailed track provided in
Pajur and Saaroja (
2020). To avoid firm selection bias, the sample was collected by
Pajur and Saaroja (
2020) by using four different sources as follows. First, the Google-based search with different sustainability keywords was conducted to find firms having relevant notifications on their website. Second, the first search was complemented with firms achieving a CSR label in Estonia. Third, the latter searches were complemented with national award-winning Estonian firms. Finally, firms not present in the first three pools were complemented with those present in the Estonian Competitiveness Chart. The latter four-step sampling strategy resulted in 452 firms that had some sustainability-related information on their websites.
The final sample in this study included 421 observations, as for 31 firms additional information about dependent and control variables was not fully available. Because of the versatility of sample composition, this potentially provides a representative perspective of Estonian firms posting their sustainability initiatives on websites. It should also be pointed out that the majority of Estonian VAT-responsible firms either did not have a website or had one listing only basic information, without any focus on sustainability.
The sample was balanced over different firm characteristics (see also
Table 2), with none of the firm types dominating. Namely, the breakdown of firms through size groups was as follows: 140 micro-, 106 small-, 102 medium- and 73 large-sized firms. Out of the sample, 37.5% of firms were majority foreign-owned, while for the rest domestic owners dominated. The highly aggregated sectoral breakdown was as follows: agriculture and mining 5, manufacturing 88, construction 45, sales 132, services 151. The average age of a firm in the sample was 19 years (SD = 11.5), therefore evenly representing entities from young to old. Thus, the threat that the analysis would be firm context-specific was minimized.
The dependent variable (see
Table 3) of the study focused on failure risk (coded as FR), and the most-cited recent universal tool by
Altman et al. (
2017) was applied in this study. Specifically, the model with the largest number of control variables to account for various firm-specific risks was applied from that study (see Model 8 in
Altman et al. (
2017, p. 154) in the last column of the respective table). The latter logistic regression model from
Altman et al. (
2017) includes four classical and widely used financial ratios, namely working capital to total assets, retained earnings to total assets, earnings before interest and taxes to total assets and book value of equity to total debt. Besides these financial ratios, the model includes various controls, respectively portraying year dummies, size, age, country risk, and industry dummies. The respective model has a high precision (by means of area under the curve) in the Estonian context, and thus, there is no need to apply a comparative local model. Moreover, using a well-established universal failure risk determination tool helps to generalize the study’s results to other environments. The input needed to calculate the
Altman et al. (
2017) model’s values in this study originated from Bureau van Dijk’s Amadeus database.
The three independent variables focused on the sustainability initiatives the firm had implemented. In
Pajur and Saaroja (
2020), the sustainability initiatives disclosed on the websites were classified based on their content to detailed categories of sustainability (9 for environmental and 7 for social) by using the well-known Global Reporting Initiative standards. A similar approach has been applied in earlier research (
Horváth 2017;
Horváth et al. 2017b). In this study, the number of different environmental (coded as ENSU) and social (coded as SOSU) sustainability initiatives was applied. In addition to using ENSU and SOSU separately, the summed count of initiatives was applied (SUSUM = ENSU + SOSU). The latter provided a holistic view of the linkages, as specific initiatives could potentially lead to varying results, which in turn could differ from the results obtained from the full complex of initiatives. The collection of CS information by
Pajur and Saaroja (
2020) was conducted in the beginning of 2020 to enhance the comparability with the fiscal year 2019 financial performance, while in order to enhance reliability, the coding protocol was established and the respective process administered by two researchers. The number of different environmental sustainability initiatives (ENSU) ranged from 0 to 9, while it was from 0 to 7 in respect to social sustainability (SOSU) in this study. Derived from the latter, SUSUM ranged from 0 to 16.
Relying on past research (e.g.,
Akben-Selcuk 2019;
Barbosa et al. 2022;
Arora and De 2020) and in order to disclose various contextual variations, multiple controls were appended to the study. These can be followed in
Table 3 and portray the size (coded as SIZE), age (AGE), foreign ownership (FOWN) and high-level sectoral (SAGRI, SMAN, SCONS, SSALE) contexts of the firms, while for the latter the service sector remains as the base category.
As the aim was to find out whether the greater volume of either or summed initiatives leads to higher or lower failure risk, ordinary least squares regression (OLS) was applied in SPSS statistical package. For that purpose, we used failure risk calculated from the year 2019 financial data as our base model. In order to find out whether the results were not subject to a single year bias, the same analysis was repeated with year 2018 failure risk, as most of the initiatives were expected to have started earlier than in 2019. In addition, the usage of samples could result in a portion of observations having a strong influence on the final estimates. Thus, we conducted additional bootstrapping with 50 samples by using the year 2019 failure risk to find out the effect of subsamples on the final results. Because of the high significant correlation (0.74 with
p < 0.001) between ENSU and SOSU, we ran separate regressions with these independent variables rather than applying them in a single regression. Indeed, it is logical that firms involved in more sustainability initiatives might focus on both social and environmental contexts. Moreover, the latter organically enabled obtaining “pure” results of how both of those independent variables associate with failure risk. Lastly, we broke the sample in two based on whether the firm was an exporter or not and reran the regressions with year 2019 data. The latter originated from the fact that exporters could be more active investors in sustainability initiatives (e.g.,
Sardana et al. 2020).
4. Empirical Results
The descriptive statistics are provided in
Table 4. Firms in the sample usually reported a few sustainability initiatives, as the means for ENSU and SOSU are respectively 2.05 and 1.38, summing the same value for SUSUM to be 3.43. The medians equaling zero for ENSU and SOSU point to the fact that firms chose either of those initiatives, rather than focusing on both simultaneously.
In turn, the median value of 1 for SUSUM indicates that the majority of firms were focusing at least on one initiative. Still, the high standard deviations for those three variables reflected a remarkable fluctuation in the number of initiatives. Both failure risks, i.e., FR2019 and FR2018, calculated based on the financial reports reflect a low threat of corporate collapse and high financial resilience. Indeed, many of the entities included in the sample were top ranking Estonian firms. The descriptive statistics of control variables are not provided herewith, as the frequencies of their classes were already disclosed in the study design section.
Table 5,
Table 6 and
Table 7 document the results for the OLS regressions composed with either ENSU, SOSU or SUSUM as independent variables and FR
2019 or FR
2018 as the dependent variable. For all regressions, the higher number of CS initiatives indicates a significant increase in firms’ failure risk, although it should be pointed out that the
p-values for ENSU were much lower than for SOSU for both years (i.e., 2018 and 2019), therefore reflecting a weaker link in the case of the latter independent variable. Still, for SOSU, the results remained under the universally acceptable threshold of
p < 0.05 as well. The year 2019 results were reconfirmed with the previous year’s failure risk (FR2018), reflected through specific columns in
Table 5,
Table 6 and
Table 7. In addition, the bootstrapping of FR
2019 revealed that the coefficients of independent variables did not change signs, indicating that the sample of firms is relatively homogenous. Therefore, the findings can be considered reasonably robust, i.e., the periodization and sampling are likely not to affect the findings.
Based on the additionally calculated marginal effects (with the dependent FR2019), ENSU’s change (dy/dx = 0.0065) affected FR more than SOSU’s (dy/dx = 0.0057). Similar to single initiatives (i.e., ENSU or SOSU), the total number of initiatives (SUSUM) had a positive coefficient and was significant in respective regressions (see
Table 7). In the case instead of SUSUM, the joint effect of two sustainability initiatives in the form of ENSU×SOSU was applied, it also remained significant at
p < 0.001 with a positive sign. This indicates that besides the total number of initiatives, their joint effect led to the same conclusion. The explanatory power of regressions by means of R
2 was around 0.3, while in empirical economics the given figure has usually been lower (
Eisenhauer 2009).
Friede et al. (
2015) reported that for 1902 empirical studies analyzed, the average correlation of sustainability initiatives was only 0.118. In
Friede et al. (
2015), only 2 meta studies out of 25 with a relatively small number of papers (respectively 22 and 31 papers) reported a 0.3 correlation between the two phenomena, while those analyzing more than 100 papers all reported the correlation to be below 0.2 (and several even below 0.1). The correlations in this study were respectively 0.30 between ENSU and FR
2019, and, 0.24 between SOSU and FR
2019. Thus, the results obtained in this study indicate the strength of association to be well above the majority of what the extant literature has found. Still, by classical statistical standards, the correlations in this study can be considered weak, as the breakeven between weak and moderate has been noted to be 0.3 (see
Gerber and Finn 2005). The models were free from multicollinearity threat, as the highest correlation between variables (independent and control) did not exceed 0.4 threshold in this study.
The control variables in both regressions indicate that larger firms (SIZE) were in higher and foreign-owned firms (FOWN) were in lower failure risk. The latter can be logically explained by better capitalization of entities, where a cross-border parent is present. Concerning the variable SIZE, a probable explanation is that as there was a significant increase in sustainability initiatives through firm size categories (the SUSUM medians being respectively 0, 1, 2 and 6 from micro to large firms’ categories), the costs of initiating and keeping them demanded more resources, therefore reducing performance. A noteworthy finding is that the standardized coefficient of SIZE is in all regressions much larger than for the independent variable (either SOSU, ENSU or SUSUM). Other controls are mostly insignificant throughout the composed regressions.
As a separate analysis, the sample was broken in two, depending on whether the firm was an exporting entity in 2019 (N = 234) or not (N = 187). The parametric ANOVA and non-parametric median tests clearly point to the fact that exporters included in the sample were characterized by significantly more sustainability initiatives. For instance, the mean and median for SUSUM for exporters were 4.1 and 1.0, respectively, while the same figures for non-exporters were 2.6 and 0, respectively. The succeeding regression analyses in the two sub-populations led to the following results. First, when the regressions were repeated in the exporters’ pool, none of the independent variables (ENSU, SOSU, SUSUM) were significant. Second, in the pool of non-exporters, in turn all of the three independent variables were significant and the association was more pronounced when compared with those documented in
Table 5,
Table 6 and
Table 7. Thus, the positive association of failure risk and sustainability initiatives was dominatingly determined by the same phenomenon among firms active in the local market. Indeed, in most countries, the latter firms make up the vast majority of the firm population.
5. Discussion of Findings
The median values presented in
Table 4 indicate that an average firm is not paying attention to both initiatives at the same time, while it has implemented one initiative of either kind. Therefore, the analyzed firms could on an average be considered modestly focused on sustainability. Similar to previous research (e.g.,
Lawrence et al. 2006;
Aras et al. 2010;
Kantcheva 2016;
Lääts et al. 2017), the additional analysis of sustainability initiatives by firm size groups showed that smaller companies tend to have lower interest in sustainability initiatives. As the studied sample can be considered to a certain extent shifted towards firms that were likely to have implemented at least some sustainability initiatives, it could be deduced from the latter that sustainability initiatives are not widespread in the general population of Estonian SMEs.
The results enable accepting H1a postulating the higher short run failure risk of firms engaged in more sustainability initiatives, while the latter holds in the case of all initiatives, i.e., for environmental, social and combined sustainability initiatives. Respectively, H1b postulating the opposite of H1a is therefore rejected.
The results support theories postulating poorer performance of more sustainable firms, at least in the short run perspective. In particular, the theoretical concept of
Amankwah-Amoah and Syllias (
2020) postulating that more focus on sustainability potentially increases failure risk in the short run was validated with the current study. In addition, the results were in line with the value-destroying theory (
Yu and Zhao 2015) and short term managerial-incentives-based explanation by
Bénabou and Tirole (
2010), who concluded that managers who need to satisfy owners’ profit expectations and who are awarded for that tend to choose financial aims ahead of sustainability objectives. More generally, the latter is in accordance with the agency-theory-based explanations of the negative effect (
Akben-Selcuk 2019;
Lee and Lee 2019;
Krüger 2015). A practical explanation could point to the fact that sustainability initiatives just do not pay off financially, at least in the short run (
Peylo and Schaltteger 2014). More generally, this could be explained with the theoretical perspectives of obfuscation and selective disclosure pointing out that favorable developments are quickly and excessively presented, in order to reduce the negative effects from underperformance (
Lukason and Camacho-Miñano 2019). Indeed, this phenomenon could be especially characteristic to start-up firms, which have not exceeded the break-even point to be profitable.
The findings contrasted a considerable amount of empirical research (
Alshehhi et al. 2018;
Friede et al. 2015;
Orlitzky et al. 2003) presenting the more likely positive effect of sustainability initiatives. The usually applied FP measures (e.g., profitability ratios) capture firms’ performance in a less complex way compared to aggregate indicators such as failure or survival probability. In addition, it has been long established that financial performance of a firm can be affected by a large number of internal and external determinants (e.g.,
Hansen and Wernerfelt 1989;
Rumelt 1991). Failure prediction models (including the one applied in this study) usually include a variety of financial indicators, accompanied by other firm-specific and environmental characteristics. The composition logic of such models also positions different firms in a ranking in comparison to each other. Thus, the given approach is less vulnerable to limitations inherent to single financial indicators, the values of which can be more random in time and contingent on specific context.
Of specific findings, the results were robust in respect to which sustainability initiatives were considered. Some earlier studies (e.g.,
Han et al. 2016;
Bătae et al. 2021) indicated a conflicting behavior of different sustainability investments, while this study’s results are less radical. Namely, only the strength of the association of different initiatives varies, more environmental sustainability initiatives leading to a larger increase in failure risk when compared with social ones. Indeed, such a finding could be explained by a certain financial logic, as environmental initiatives might per se demand larger investments, which in turn translate into respective costs.
The study indicates that in the pool of independent and control variables, sustainability initiatives are one of the few having a significant relationship with failure risk. From the control variables, size and foreign ownership were systematically linking to failure risk, respectively the former positively and the latter negatively. In addition, the standardized coefficient of size indicates it to be a more important predictor of failure risk than the sustainability performance. While such an interconnection itself is not surprising, an unusual feature was that the increase in firm size led to greater failure risk. As indicated earlier, this might be explained by the fact that as the majority of studied firms were financially quite well off, because otherwise they probably might not have had funds for sustainability investments at all, then ceteris paribus, larger firms that made more sustainability investments also reduced their short term financial performance more.
An additional important finding concerned the exporting activities of the analyzed firms. Firms engaged in exporting showed no significant association with any of the variables reflecting sustainability initiatives. This could mean that in the target markets of Estonian firms, of which the Nordic countries are the most prominent (
Vissak and Masso 2015), high attention was paid to sustainability initiatives. As many of the exporting firms are foreign-owned, often by owners originating from their target market, putting these two facts together could organically mean that Nordic-owned firms with Nordic markets are rather homogenously sustainable. Indeed, firms in Nordic countries have been long known to be the frontrunners in sustainable development (see e.g.,
Sustainability for all 2021). In turn, in the case of firms with local market orientation, the initiatives do not seem to pay off in the short run. It might be that firms voluntarily engaged in initiatives are automatically less well off when compared with their competitors, which without a state’s regulatory pressure might be very reluctant to adopt sustainability in their business models, partly because Estonian customers do not seem to value sustainability enough (
Kantcheva 2016).
6. Conclusions
This paper looked at the association of different corporate sustainability initiatives and firm failure risk with a sample of Estonian firms of varying sizes. As the main scientific conclusion, we would postulate that frequent adherence to sustainability initiatives could increase firms’ failure risk, at least in the short run. Of course, the latter does not mean that such firms would be in an actual threat of failure.
Whether the initiatives pay off in the long run, will remain an avenue of future research. In addition, while this paper focused on the association, one should acknowledge the challenges connected to setting up a study design to outline both the short and long term causal effects of initiatives. For instance, one would probably need factual information about the change of customer preferences to buy a certain product or service because of increased sustainability of a firm. In addition, the profitability analysis of sustainability initiatives would demand precise information about the money invested in those activities, which is usually not available through public financial information, especially for SMEs. A limitation of this paper to be resolved in future studies is that it looked only cross-sectionally at the relationship between sustainability initiatives and firm failure risk to validate a specific theoretical concept and resolve the controversies in earlier theoretical and empirical literature. For the portrayal of a longitudinal causal relationship one would need, besides the proper variables, their dynamic reflection over a lengthy timeframe. Still, multiple years and bootstrapping applied in this study provided sufficiently strong evidence that firms at least denoting their greater commitment to sustainability might not be as well off financially as their counterparts in the short time horizon.
Multiple practical implications can be derived from the results. First, corporate managers should acknowledge that performance declines due to (over)investing in sustainability initiatives could be the likely reality. Thus, a proper profitability analysis of the implementations by the firm’s management should be a rule rather than an exception. A challenging facet of the latter is to forecast the long term revenues and costs of sustainability investments, while the latter could benefit from the fact that firm valuation methodologies have advanced enough in the “start-up era”, in which classical discounted cash flow approaches have been deemed to be insufficient. Probably, firms should choose one or a few most beneficial and feasible initiatives rather than implementing a wide range, which they cannot handle, therefore leading to value destruction. Corporate stakeholders (e.g., creditors and suppliers) should be aware that excess focusing on sustainability should be taken conservatively, as firms’ classical financial indicators (e.g., liquidity and profitability as an input to failure risk calculation) could be impacted negatively by that tendency. Namely, the nice façade of a firm might not match the interior. Public sector institutions that are determining and monitoring sustainability strategies the corporate sector is subject to should carefully consider not to exaggerate with the additional burden of activities set on firms.
