Introduction
This paper explores whether investor behavior is more closely related to a monetary objective only (wealth maximization) aligned with the shareholder approach, or both monetary and social objectives (welfare maximization) aligned with the stakeholder approach. These financial and social preferences can differ among investors, as they may have varying risk appetites, distinct opinions, and unique expectations. This heterogeneity may also come from their socio demographic profiles; in our study, we focus on age and gender since young and old investors, as well as female and male investors, may have different preferences. Men, typically associated with agentic traits, may focus solely on financial objectives, while women, often associated with communal traits, are likely to include social considerations as well. Furthermore, young investors presumably staying longer on the planet may be reasonably more oriented to social objectives (environmental protection, climate issues, etc.) than older investors.
To thoroughly explore our research question: "What are the preferences of individual investors for CSR?", we opted for an experimental approach based on a trading simulation. This research design is particularly well-suited as it facilitates an in-depth investigation of investor preferences at the individual level (Kagel and Roth, 1995). By replicating real-world trading scenarios within a controlled environment, our simulation enables us to observe and analyze the decision-making process of investors when confronted with CSR-related events. This approach not only offers direct insights into their preferences but also allows us to isolate and understand the specific influences of CSR on individual investment choices, providing a robust framework to examine the intricate dynamics between CSR and investor behavior. We collect individualized data about participants: their profile (including our moderating variables, age and gender) and their trading reaction to a simulated corporate donation. Market participants react to the news of the corporate donation by trading (buy, sell, hold) according to their preferences for CSR. The methodology used in our research allows us to make causal inferences by manipulating our independent variable (the amount of the corporate donation) in a controlled setting. We observe trading decisions at the individual level, allowing us to infer whether the preferences of each participant are closer to a monetary objective only and to both monetary and social objectives.
Theory
The debates around shareholder and stakeholder theories, while pointing at the macro-level (i.e., firms), exert a significant influence at the micro-level (i.e., investors). These investors, far from conventional economic models which assume them to be homogeneous, equivalent “representative agents” (Lucas, 1978), hold in fact different expectations, opinions and needs (Kirman, 1992). They may also differ in their appreciation of CSR, leading them to different trading behavior. For investors, trading is a medium of expression: they will buy stocks if they like the CSR policy of the firm; they will sell stocks if they don’t like the CSR policy of the firm. Moreover, in financial markets, a complex feedback loop often emerges, driven by certain market participants who anticipate the behaviors of others. This phenomenon suggests that individuals base their decisions not only on available market information but also on their predictions about other market players' actions and reactions.
Figure 1 visually summarizes the macro and micro relationships involved in our research and situates where our contribution stands (based on Coleman, 1994). This macro relation may be better understood by studying the micro behavior of individual investors as we do in our experiment. The macro level reflects the fiduciary duties of firm managers and board directors influencing their actual CSR-related behavior. The corporate social responsibility of firms, which may be closer to the shareholder approach or the stakeholder approach, may influence the preferences of individual investors reflecting a monetary objective only (profit maximization) or both monetary and social objectives (welfare maximization). This macro-to-micro influence may take place through ESG information disclosure by firms, SRI products proposed by financial institutions, the regulatory changes, the political debate, and the business media.
In our experiment, following the firm decision to make a corporate donation (the CSR event in our experiment), the trading reaction of individual investors may reflect their financial and social preferences. Moderating variables such as age and gender may help to better explain the mechanism at the micro level. A feedback loop from (some) market participants considering the behavior of other market participants (rational expectations) may take place. The micro-to-macro relationship corresponds to the feedback effect of the stock market (which results from the aggregation of the reactions of all market participants) on firms’ CSR behavior.
Hypotheses development
Based on the theoretical perspectives exposed above, our experiment tests several hypotheses related to individual investors’ reactions to the announcement of a corporate donation. Figure 2 below illustrates the impact of a corporate donation on firm value for different amounts.
Our hypothesis are as follows:
- Hypothesis 1 (monetary objective and short-term view): Market participants always sell stocks when the company announces a corporate donation, and the higher the amount, the higher the quantity of their sell orders.
- Hypothesis 2 (monetary objective and long-term view): Market participants sell stocks when the company announces a corporate donation with a low amount, buy stocks when the company announces a corporate donation with a medium amount, and sell stocks when the company announces a corporate donation with a high amount.
- Hypothesis 3 (monetary and social objectives): Market participants sell stocks when the company announces a corporate donation with a low amount, buy stocks when the company announces a corporate donation with a medium amount, and buy stocks when the company announces a corporate donation with a high amount.
- Hypothesis 4 (gender effect): male participants follow H1 or H2, and female participants follow H3.
- Hypothesis 5 (age effect): old participants follow H1 or H2, and young participants follow H3.
RESULTS
Our most important result is the different behavior of younger (Gen Z) compared to older (Gen X and Y) investors, thus revealing their different preferences about CSR. While older investors’ reaction follows a “too little-too much” pattern, remaining closer to the instrumental stakeholder view, younger investors’ reaction follows a “never-too-little” pattern, remaining closer to the pluralistic stakeholder view.
Studies about generations (e.g. Duffy, 2021) contend that it is possible that individuals from the same generation maintain some attitudes or behaviors over time. If that were the case of Gen Z investors, they would keep their current higher preferences for CSR during the next decades. In this sense, the aggregation of micro outcomes (gradually more individual investors adhering to the pluralistic stakeholder view), would have macro impacts on the market, as the Coleman diagram (Figure 1) explains. Furthermore, we contend that this possibly ongoing change in the stock markets would have a feedback effect on firms’ behavior, leading corporate boards to a higher commitment to CSR, and on asset management firms, leading fund managers to a higher attention to CSR performance.
