Abstract: In the wake of the Enron scandal, ethical fraud continues to be a major concern for organizations. Both professionals and academics advocate for an increased emphasis on ethics in business education. A significant portion of the current literature relies on self-reporting surveys to evaluate the effectiveness of business ethics education in shaping students' understanding of ethical issues. However, this research approach fails to provide conclusive evidence about students' actual behavior in response to ethics education. In a controlled laboratory experiment, I found that students who underwent ethics education demonstrated less ethical behavior compared to their counterparts who did not receive such education. The implications of this unexpected discovery are further examined in this study.

Keywords: ethics education, students' ethical decisions, experiment

Citation: Chaoping Li, The Effect of Ethics Education on Students' Ethical Decisions: A Preliminary Laboratory Experiment. Journal of Finance and Accounting, 11 (1). 14-18. January 2023. doi:10.12691/jfa-11-1-2

1. Introduction

Despite the extensive adoption of social responsibility initiatives and organizational modifications designed to encourage ethical conduct in practice [1], the number of scandals persistently grows each year (e.g., Wirecard, Luckin Coffee, and Beam Financial). This escalating concern regarding unethical behavior drives organizations to search for effective solutions to these issues [2].

In response to corporate ethical misconduct, business schools have been called upon to provide ethics education as a means to address these concerns. This need is acknowledged globally by The Association to Advance Collegiate Schools of Business (AACSB), and ethics scholars have also advocated for business schools to play an active part in resolving integrity dilemmas [3]. Although the ethics education literature indicates a growth in the number of ethics courses offered in business schools over the past three decades, traditional pedagogical approaches often result in substandard ethics education quality [4].

Ethics education in business schools concentrates on enhancing students' ethical knowledge, encompassing ethics awareness, moral reasoning, and ethical judgment. Nevertheless, faculty predominantly utilize "external approaches," such as punishment, to tackle ethical issues [5]. This methodological focus could potentially trigger an ethical backlash, resulting in unforeseen consequences.

While there is ample evidence in the literature regarding the quality of business ethics education, most studies predominantly depend on self-reported surveys. The influence of business ethics education on students' ethical behavior remains uncertain, as possessing ethics knowledge does not necessarily lead to ethical actions. For example, Enron Corporation's former CFO remarked in an interview with Fraud Magazine at the 2015 ACFE Asia-Pacific Fraud Conference, "You could tell people to be ethical, have beautifully written statements about company values and all that, but you have a CFO who does a deal that's intentionally misleading to the outside world" [6]. As a result, it is crucial to reassess business ethics education and take into account its potential shortcomings to create a new educational model for business ethics [7,8].

In this study, I utilize a controlled lab experiment to conduct a preliminary investigation of the impact of business ethics education on students' actual ethical behavior. During the experimental task, students have the opportunity to unethically enhance their personal economic gain. My findings indicate that students who have undergone ethics education exhibit less ethical behavior compared to those who have not. This result suggests that students with ethics education have a more profound understanding of internal control systems than their peers without such education. In the absence of internal controls to supervise behavior, these students tend to prioritize self-interest, even if it results in unethical decisions.{1}

This research makes several significant contributions to both the academic and practical realms. Academically, it addresses the existing gap in the literature by examining the influence of business ethics education on students' actual ethical behavior, rather than relying solely on self-reported surveys. The study's findings challenge the prevailing assumption that ethics education leads to improved ethical behavior and provide valuable insights into the potential drawbacks of traditional pedagogical approaches in ethics education. Moreover, this research expands our understanding of the relationship between ethics education and internal control systems, paving the way for further investigations in this area.

From a practical perspective, this study offers crucial implications for business schools, educators, and organizations alike. By highlighting the limitations of conventional ethics education, it underscores the need for innovative educational models that more effectively cultivate ethical behavior. These findings can serve as a catalyst for business schools to re-evaluate their ethics curricula, considering alternative pedagogical methods, and fostering a more comprehensive understanding of ethical decision-making processes. Additionally, organizations can utilize the insights gained from this research to design more effective internal control systems, ultimately promoting a culture of ethical conduct and reducing the likelihood of corporate scandals.

2. Literature Review and Research Question

From Enron and WorldCom to Volkswagen and Wells Fargo, the continuous occurrences of corporate ethical misconduct have substantially undermined public trust in the business world [9,10,11]. Simultaneously, business schools have encountered criticism for their pedagogical approaches, which emphasize profit maximization and shareholder value while overlooking the broader societal and environmental contexts in which businesses operate [10]. These unethical incidents and public critiques underscore the significance of integrating business ethics as a key element in higher education curricula [9], given that colleges play a vital role in molding social ethics and values. Furthermore, business ethics courses have the potential to heighten students' ethical awareness and cultivate a shared understanding of common issues [12]. Sims and Sims [12] outline three objectives of ethics education in business schools: to increase students' sensitivity to ethical issues in the workplace; to help students develop moral reasoning and apply it to ethical dilemmas; and to elevate students' moral aspirations.

Generally, business ethics education is offered in two formats: as a stand-alone course or as an integrated component within a business course. In a 1989 survey conducted by Armstrong and Mintz [36], 7.3% of the 137 AACSB-accredited schools provided stand-alone graduate ethics courses. Concurrently, Cohen and Pant [13] reported that 40% of the schools in their survey offered stand-alone ethics courses at the undergraduate level. In a more recent survey, Robinson et al. [11] discovered that 53% of colleges presented stand-alone ethics courses at the undergraduate level, with 63% of these being mandatory. This increasing trend over the past 30 years implies a growing acknowledgment of the significance of ethics education in business schools. Moreover, business students also perceive ethics education as essential and believe it should be taught in school [14,15,16].

Despite the growing emphasis on the value of ethics education, debates regarding its effectiveness continue [5,12,17]. Through a quasi-experiment, Gautschi and Jones [18] discovered evidence that business ethics education enhanced students' ethical sensitivity. Martinov-Bennie and Mladenovic [19] provided a framework for ethics education, finding that it aided students' ethical judgment but not their ethical sensitivity. However, an integrated ethics component did improve students' ethical sensitivity, with the effect being even stronger for those who had not previously received such education. May et al. [20] investigated the impact of ethics education on moral efficacy, moral meaningfulness, and moral courage. They found that students enrolled in business ethics courses exhibited higher self-reported values in these three areas compared to those who did not. Using a survey, Jones [21] and Lau [22] obtained similar results, with ethics education enhancing students' moral reasoning, ethical awareness, and ethical judgment. MacFarlane [23] demonstrated that students with ethics education experience possessed a deeper understanding of complex ethical issues. Halbesleben et al. [24] documented that ethics courses reduced the self-reported likelihood of engaging in unethical acts.

On the other hand, Rafinda et al. [8] found that ethics training does not enhance students' moral reasoning abilities. Jewe [25] investigated the impact of business ethics education on students' ethical perspectives and discovered no significant effect on their ethical attitudes after completing a business ethics course. Similarly, Allen et al. [26] argued that emphasizing ethics in course material does not improve students' ethical awareness. Fraedrich et al. [27] determined that ethics education does not influence student survey responses. Based on a meta-analysis, Waples et al. [28] suggested that the influence of business ethics instruction on moral perception, awareness, or behavior is negligible. Furthermore, Tormo-Carbó et al. [29] and Fraedrich et al. [27] revealed that business ethics education can negatively affect students' perceptions and their preference for honesty. Lowery et al. [30] discovered that participants who had not received ethics education held stronger views against unethical conduct than those who had.

Several factors contribute to the ineffectiveness of business ethics education, as documented in the literature. First, a materialistic culture: Giacalone and Promislo [1] argue that the prevailing materialistic ideology is ingrained in many students from an early age, making it challenging to teach them business ethics. Second, ineffective teaching content: Hillard and Dent [4] assert that despite the AACSB calling for balanced content, most business ethics courses focus on negative aspects and unethical actions. Third, inappropriate design of business ethics content: Park [7] suggests that the cognitive reasoning incorporated in the content turns business ethics education into "defensive reasoning" within the business management context, while "strategic thinking models" overlook the development of moral reasoning. Fourth, a shortage of high-quality ethics education resources: Dean and Beggs [31] and Evans and Weiss [32] report a lack of properly trained faculty to teach ethics based on survey results. Fifth, a lack of motivation to teach ethics: Beggs and Dean [5] found that faculty members do not view ethics as a crucial subject and allocate more class time to technical discipline topics.

Although the quality of ethics education in the literature is inconsistent, most results are derived from survey-based methods, relying heavily on self-reported data. However, positive ethical attitudes, moral reasoning, or ethical perceptions do not necessarily translate to moral behavior. Additionally, ethical knowledge does not transfer across contexts [24]. For instance, Simha et al. [33] found that business ethics education and training improved students' attitudes toward academic dishonesty but did not affect their actual cheating behavior. As mentioned earlier, materialistic ideology dominates today's culture, which may result in a discrepancy between students' ethical perceptions and their actual ethical conduct.

Despite the varied student responses to unethical situations found in the literature, the effect of ethics education on students' actual behavior remains unclear. Therefore, this study aims to address the research question:

Compared to students without ethics education, how will students with ethics education act when confronted with an ethical decision involving real economic consequences?

3. Research Methodology

3.1. Experimental Task

In this study, a budget-request experiment is conducted to examine the research question. Student participants assume the role of managers, requesting production cost budgets from a hypothetical company. Both the company and the managers are aware of the production cost range, which is between 4.00 lira and 6.00 lira. However, only the managers possess knowledge of the actual production cost, which is not accessible to the company. Managers have the option to request a cost budget higher or lower than the real cost. If a manager requests a budget exceeding the actual cost, they can keep the difference as personal compensation. The participants are informed that their requested budget will not lead to the company's bankruptcy. Furthermore, managers receive a fixed salary of 250 lira as part of their personal compensation. The total compensation for a manager is calculated as follows:

Each manager is given a payoff table that presents all potential earnings for both the company and the manager, based on the requested costs. In each period, a randomly selected actual cost is disclosed to the managers.

3.2. Experimental Procedure

In this study, I employed a 1x2 between-subjects design, in which the between-subjects factor was Ethics Education (yes vs. no). This variable was manipulated by asking participants in a post-questionnaire whether they had previously taken an ethics course.

Upon arrival at the lab, each participant received a unique identification number, which was used throughout the entire experiment to ensure that responses could not be traced back to specific individuals. Participants read and signed consent forms containing general information about the study, its purpose, and the compensation they would receive for participating. They were then randomly assigned to one of four experimental conditions.

The experimenter introduced the budgeting task and administered a pre-task quiz to assess the student participants' understanding of the task. The experiment consisted of two practice periods and five task periods. Before the task periods began, the experimenter privately addressed any questions. Subjects were given the same actual cost for each task period across all experimental conditions. The main task involved requesting a production cost budget. Once the five periods were completed, participants filled out a post-task questionnaire. They were compensated at an exchange rate of 50 lira = 1 dollar, with the payment period randomly selected from the five task periods.

4. Results and Discussion

A total of 64 undergraduate business students participated in the study, with each session lasting approximately 45 minutes. About 41 percent of the participants were female, and the mean age was close to 23 years old. On average, each subject received a payment of 10 dollars.

The dependent variable, unethical reporting, was calculated by taking the difference between the budgeted cost and the actual cost, then dividing it by the difference between the highest reported cost (6 lira) and the actual cost. This approach helps account for the impact of the actual cost on overbudgeting. The dependent variable's value ranges from 0 to 1, where 1 signifies the highest level of unethical behavior within the task. To examine the research question, I conducted an ANCOVA analysis, and the results are presented in Table 1.

Table 1, Panel A, displays the aggregated mean over the five periods, revealing that participants who had not taken an ethics course prior to the study tended to over-budget less than those who had (0.22 vs. 0.38). Panel B of Table 1 presents the ANCOVA results, in which I also accounted for gender, age, and individual preference for honesty{2}. Since I employed a multi-period task, I controlled for period and subject effects as well. The analysis indicates a significant effect of ethics education (p-value = 0.01). Additionally, I discovered that individual preference for honesty (p-value < 0.01) and age (p-value < 0.01) also impacted the subjects' behavior during the task. However, no gender effect was found (p-value = 0.28). Our findings suggest that students who have taken an ethics course exhibit less ethical behavior than those who have not.

Table 1. Unethical Reportinga

While numerous studies provide evidence that ethics education enhances students' moral reasoning and ethics awareness, the literature demonstrates that this effect is relatively minor. There is a lack of evidence on how ethics education influences students' actual ethical decisions, as most research relies on survey methods. This study indicates that ethics education could have a negative impact on students' ethical decision-making when real economic utility is at stake. It implies that students' ethics knowledge may not necessarily translate into ethical behavior. For instance, I found responses in an open-ended question{3} such as "[m]aximizing to a certain extent both my own earnings and the compa[y's] earnings simultaneously," "[m]y earnings compared to the 50 Lira to $1 exchange rate," and "I could've easily reported a cost of 6.00 to maximize my earnings since there were no internal controls." These comments came from subjects who had taken ethics courses before. Although responses like "[p]ersonal ethics and morals" were found in the questionnaire, overall, students with prior ethics education made less ethical decisions compared to those without such education. Considering the evidence, this study suggests that current ethics education in schools is not effective in shaping students' ethical behavior, even though it does improve their understanding of ethical issues.

5. Conclusions

This study employs a controlled lab experiment to directly investigate the impact of ethics education on students' actual ethical decisions. It implies that the current ethics education in schools may be inadequate. Present education mainly emphasizes ethical theory and the examination of unethical issues [34,35]. By using case studies, students are taught to identify relevant stakeholders and analyze their interests. This approach assists students in understanding how to treat each party fairly, with the assumption that they can apply the knowledge gained from academic training to real-world ethical dilemmas [35]. However, this study reveals that this assumption may not hold true and could even produce unintended consequences in real-life situations. As a result, incorporating behavioral ethics into the current ethics education system appears crucial for enhancing its positive impact.

In addition to the findings, this exploratory study has limitations that could inform future research. The study concentrates on the overall quality of ethics education without examining the underlying causes. Future research could explore the reasons behind the negative impact of ethics education on students' ethical behavior. It is also unclear whether this adverse effect is consistent between stand-alone ethics courses and integrated ethics components within business courses. Ethical behavior is more intricate and challenging than simply possessing ethics knowledge. Connecting this knowledge to actual behavior would be a valuable avenue to pursue.

This study contributes significantly to both academic and practical domains by examining the influence of business ethics education on students' actual ethical behavior, challenging the existing assumption that ethics education leads to improved ethical behavior. It highlights the limitations of traditional pedagogical approaches in ethics education and offers insights into the relationship between ethics education and internal control systems. This study underscores the need for innovative educational models that more effectively cultivate ethical behavior, leading to a more comprehensive understanding of ethical decision-making processes. Additionally, organizations can use the insights gained from this research to design more effective internal control systems, ultimately promoting a culture of ethical conduct and reducing the likelihood of corporate scandals.

Notes

{1}. I did not design an internal control system in the experiment task to prevent unethical behaviors because the goal of the present study is to examine how ethics education per se affect ethics behaviors. Implementing such a system would deviate the goal of the study.

{2}. Individual preference for honesty is measured with two questionnaire items: It is important to me that I am honest in everything I say and do (question #6); It is unethical to report a cost higher than the actual cost (question #7). We used the average value from the two items.

{3}. The open-ended question is “[i]n addition to the above statements, are there other factors that you considered when making your reporting decision in each production period?”
