How do we think about sustainable investing? Suggestions from an exploratory study

By Margherita Massazza & Dr. Kristjan Jespersen

From the outset, this blog post takes the perspective that behavioral finance is required to assess the perceived tension in sustainable investing (SI). Our work investigates the extent to which sustainability considerations are included in investment decisions, and the drivers behind SI approaches.

Sustainability is increasingly integrated in financial markets, with the acronym “ESG” (Environment, Social, Governance) becoming an all-encompassing term widely used in all phases of the investment process. According to a recent global review, sustainable assets [1] reached USD 35.3 trillion at the end of 2019, representing 35% of total professionally managed assets, and they are set to grow further in the coming years. Yet, despite its growth and the positive sentiment associated with it, there is an inherent tension in sustainable investing.

This tension stems from the apparent disconnect between the theoretical assumptions of classical financial models, focused on risk and financial returns as the predominant determinants of investment decisions (e.g., Capital Asset Pricing Model, Modern Portfolio Theory, etc.), and the empirical evidence of SI, where portfolio allocations are affected by non-financial aspects like personal values and social pressures. How can we make sense of this tension? 

Usually, the contradiction is formulated in terms of a tradeoff between financial returns and ESG impact: in order to achieve one, investors must forego the other. However, this view is still rooted in a traditional finance perspective, according to which including ESG considerations or seeking a non-monetary impact comes at the expenses of returns.

There needs to be more nuance in how sustainable investing decisions are investigated and assessed. Given the pervasive and engaging nature of ESG issues, sustainable investing is likely shaped by internal and external forces that go beyond the financial-vs-impact debate. By acknowledging the role that cognitive limitations, biases, and the external context play for investments, behavioral finance allows to capture the financial impact of factors that tend to be overlooked in mainstream financial theories. 

Under this perspective, the authors carried out a study based on primary data from European retail and professional investors. It focused on two main questions:

To what extent are sustainability considerations included in investment decisions?

Firstly our analysis broke down the relative importance of four attributes for the investment choice, i.e. the relative weight (expressed in percentage) that each characteristic exert on the investment decision. Sustainability attributes carry a relative importance of about 38%, with ESG score displaying a 26% relevance, and the investment’s end objective a 12% relevance. Taken together, these parameters display a larger role than standard financial attributes of risk level (relative importance of 33%) and expected returns (relative importance of 29%) (Figure 1). The results confirm the significance of ESG aspects for a well-rounded assessment of an investment, arguing against the traditional perspective of risk and returns as the sole determinants of investment choices.

What drives investors to invest sustainably?

Secondly, we identified the main tendencies leading investors to engage in SI. Starting from a set of 16 heterogeneous motives, 4 main drivers emerged: a desire for self-expression, a financial-strategic rationale, the influence of the external context, and an opportunistic motive (Table 1). These drivers depict SI as a multifaceted phenomenon that unfolds along various dimensions, and not only on the financial and impact layers. They propose a novel perspective to think about SI, which takes into consideration how endogenous (e.g., alignment with values) and exogenous (e.g., role of regulation) forces may affect investments.

How can the findings help us better assess sustainable investing?

This analysis shows the extent to which ESG aspects are integrated in investments, confirming their importance for investment choices. It also shows the multidimensionality of SI drivers, which eschews the rigid perspective of traditional finance and accounts for the impact of relevant internal and external factors. 

With this understanding, it is possible to formulate practical insights for industry participants to address the current challenges of SI. In fact, there are concerns related to the over-inclusion of sustainability in investment decisions at the expenses of fundamental financial analysis, which may lead to mispricing, inflated asset evaluation, and potentially an “ESG bubble”.

  • Standardize definitions and improve sustainability communication. Social context emerged as one of the drivers of SI, and regulators have a strong role to play in harmonizing the meaning of sustainability in finance. Legislative and non-governmental bodies are working to overcome the lack of standard definition and frameworks in SI – e.g., via the European Union’s Sustainable Finance strategy. Their effort to create a common vocabulary and shared understanding of what SI entails will help to align incentives, concepts, and strategies. In parallel, the financial-asset supply side (e.g., fund providers, financial advisors, etc.) should communicate clearly and extensively on the sustainability aspects of financial products. Given the importance of ESG characteristics for investment choices, this will ensure investors have reliable and trustworthy information to guide their investments. Together, the agreement in terminology and the availability of sustainability information will reduce the possibility for misinformation and opportunistic tendencies to sway investment decisions.
  • Recognize the existence of complex drivers behind sustainable investment decisions. Investors, both professional and retail, should evaluate how different motives affect their investment choices. Knowing that multiple drivers exist will ensure that investment are aligned with goals, limiting the influence of irrationality and misinformation. This will not only benefit investment strategies, but also curb counter-productive results such as the emergence of an ESG price bubble. To explore what drives investor’s decisions, an ad-hoc survey could be submitted ahead of opening investment accounts, mirroring the logic of the MiFID directive. This may have positive effects, such as involving more retail investors in sustainable investing [2].
  • Finally, consider adopting a behavioral approach when studying sustainable investing. The flexibility of behavioral finance may allow to grasp further insights and help to think about this timely topic in a novel way.

Are sustainable and healthy diets always compatible? Needs for an emic-oriented cultural research on sustainable consumption

By Fumiko Kano Glückstad

◦ 6 min read 

It is widely acknowledged that a plant-based diet is healthier than an animal-based diet (Willett, et al. 2019). However, a group of Japanese researchers recently published a thought-provoking article demonstrating that a lower diet-related Greenhouse gas emission (GHGE) has generally resulted in an inadequate nutrient intake among Japanese adults (Sugimoto et al. 2020).

Their results seem to support the fact that the Japanese Government has excluded any dietary-related initiatives from its long-term national strategies concerning the targeted 80% reduction of greenhouse gas emissions by 2050. In other words, Japanese opinion leaders seem to challenge the generally accepted viewpoint of a direct positive correlation between a sustainable diet and a healthy diet, contradicting widely accepted European studies and initiatives (e.g. Sjörs et al. 2017). This apparent controversial observation motivated me to look into the historical development of meat consumption on a global scale. Most importantly, the recently published guiding principles by the Food and Agriculture Organization of the United Nations (FAO) and World Health Organization (WHO) in 2019 state that “Sustainable Healthy Diets” are a trade-off between the two dimensions: sustainability and healthiness of diets. Thus, countries should decide on such trade-offs in consideration with their situation and goals (FAO & WHO, 2019). 

The following figure indicates such a trade-off situation for various geographical regions and it clearly shows that the meat consumption in Western countries is obviously higher than the rest of the world such as compared to e.g., Africa or Asia, although a substantial increase of meat consumption is observed in both China and Japan.

In particular, the main increases observed in China and Japan seem to be well-synchronized with the periods of their respective economic developments that simultaneously triggered their modernization (Westernization) process in their markets. However, the curves of Japanese and Chinese meat consumption also show a noticeable difference. Whereas the meat consumption in China has steeply increased since the 1980es, Japan seems to moderate its increase from the early 1990es and ahead, which is most likely explained by their respective economic developments. However, in this blog, I want to supplement these observations with some personal insights on what has happened in Japan during this period through my work experiences in the related industry.

Meat consumption in this blog refers to the average supply of meat across the population shown in this figure. Food supply is defined as food accessible for human consumption meaning the food remaining for human use after deduction of all non-food utilizations.

During the Japanese bubble economy in the 1980es to the early 1990es, the Japanese middle class had increasingly wider opportunities to be exposed to the Western food culture due to their Westernization. This somewhat alarmed key Japanese health professionals, nutritionists, food experts and industries who considered a ”Western lifestyle and food culture” as a source of lifestyle-related chronic diseases e.g., diabetes 2 and cardiovascular issues, which would gradually impact Japanese consumers.

This subsequently triggered a countless number of initiatives aimed to nudge a wide range of the population towards a healthier diet. The initiatives were eventually formalized as a Health Promotion Act in 2002 and the Basic Law on “Shokuiku (food and nutrition education)” in 2005 by the Japanese government (MAFF, 2019).

Source: Ministry of Agriculture Forestry and Fisheries. 2019. “A Guide to Shokuiku.” https://www.maff.go.jp/j/syokuiku/guide/pdf/00_en_guide.pdf

The Shokuiku act has since become a comprehensive program targeting everyone from school children to the elderly, and its initiatives have involved a broad range of Japanese stakeholders, not only the central and local governments, health professionals and nutritionists but also food and restaurant businesses and their consumers.

The Shokuiku program has promoted the nutritional education from a holistic viewpoint and emphasized the importance of enjoying healthy meals from societal and cultural perspectives through various sensory food experiences. As a consumer researcher in the 1990es in one of Japan’s largest high-tech companies producing various kitchen appliances, I also personally participated in a variety of initiatives involving consumer organizations, health professionals, nutritionists and food and restaurant businesses to nudge consumers towards a healthy diet at that time. 

In a European context, nudging consumers towards a sustainable and healthy diet usually implies the replacement of an animal-based diet with a plant-based diet with emphasis on ingredients. One major difference to the Japanese nudging initiatives is that the Shokuiku promotion has encouraged consumers to learn how to select “nutritionally balanced meals” in their daily life while enjoying variations in sensory food experiences. Consumers have many ways to achieve this by following the “Japanese food guide spinning top” that can be easily followed by a wide range of population groups, i.e. from school children to the elderly (see the below picture). The maintenance of a moderate meat consumption level observed from the Japanese curve in the above figure might be partially attributed to such ‘enjoyable’ Shokuiku initiatives (see Yoneda, 2019).

Japan has been able to moderate its overall meat consumption without specific promotions of plant-based diets also thanks to the traditional Japanese food culture that is originally rooted in a plant-rich diet. Thus, in a Japanese context, it is perceived possible to achieve a well-balanced diet while simultaneously enjoying variations in sensory food experiences, in other words, nudging a healthy diet can be perceived as an enjoyable experience. Interestingly, Kanemoto et al. (2019) recently reported that meat consumption only weakly explains the difference between high- and low food carbon footprints (FCF) among 60,000 Japanese households. This study ponders that Japanese should (also) consider restricting their consumption in other areas than meat consumption with a higher estimated FCF such as restaurant foods, confectionary and alcohol.

These observed trends indicate the importance of fully understanding social, cultural and dietary contexts in various countries and regions when researching on sustainable food consumption because food is inherently deeply rooted in the specific cultures. In other words, sustainable consumption studies should ideally shed more light on an emic approach addressing a specific sample of that region and discuss adaptability of such studies to countries outside of the specific region with due respect of the embedded cultural contexts.

The fear of becoming the hotspot of infectious diseases: Who is concerned and why?

By Fumiko Kano Glückstad

◦ 4 min read 

Denmark is opening the borders for tourists from our neighboring countries in Northern Europe after a long period of lock-down restrictions. This is good news for the Danish tourism having suffered with substantial revenue losses as the consequence of the Covid-19 crisis. Whereas the European countries are optimistic about the opening of their societies along with the progress of their vaccination programs, Japan in the Far East is tightening its border entry restrictions due to the latest state of emergency declarations.

Recent Japanese opinion surveys clearly indicate that Japanese are concerned about hosting the Olympic Games in Tokyo expected to kick-off in just two months. At a glance, the adverse reactions by the Japanese population seem to be triggered by the current state of emergency in addition to the delay of implementing a nation-wide vaccination program.

However, such attitudes were already indicated in a cross-cultural study conducted for the period 10 – 24 July 2020 addressing residents in the following four countries: Denmark (n=1,005), Japan (n=1,091), Italy (n=1,005) and China (n=1,013). In this blog, I will present some fundamental cultural differences observed between the Europeans and the Far East Asians investigated in this study.

In an article recently published in Frontiers in Psychology by Glückstad et al., 2021, it is reported that Japanese are generally very concerned about their local community becoming a hotspot of infectious diseases. This study asked respondents how much they agree or disagree (1: Strongly disagree — 7: Strongly agree) to the statement:

It is concerning that our community will be crowded by foreign tourists and will potentially become a hotspot of infectious diseases

as well as other statements explaining several factors, amongst others: 

  • their intentions of pleasure seeking (enjoying cafés and restaurants, travelling abroad as soon as possible and similar enjoyments)
  • their risk perception (worried about becoming infected, getting ill and infecting others)
  • their risk avoidance (avoiding larger groups, public transportation and travelling to destinations with high reproduction, selecting destinations with hygiene and less crowded destinations)
  • their intention to behave responsible (keeping social distance, cleaning up public spaces, using disinfectants before and after shopping)   
  • their expectation for the society to behave responsibly (tourists visiting their local community should behave properly, local businesses should make their community clean and safe, individuals should contribute to minimize the risk of spreading, importance for their local businesses to have inbound tourism)
  • their attitudes to mask wearing and hygiene (wear mask, feel safe if businesses indicate sanitary standards and if staffs wear mask)

In our recent Frontiers article, we conducted a Bayesian Network analysis (see Fig. 1) which indicates that, in Denmark and Italy, respondents who expressed higher intentions for pleasure seeking behaviors have higher probabilities of being less concerned about their local community becoming a hotspot of infectious diseases, and vice versa.

This European trend is rational in a way that the motivational drivers to seek hedonistic experiences are conflicting with the conservative risk avoidance attitudes and behaviors. However, in Japan, disregarding the level of intentions for pleasure seeking behaviors, the level of concern about their community becoming a hotspot of infectious diseases stays around 5.5 (at the level between ‘somewhat agree’ and ‘agree’). The Chinese reacted rather similar to the Japanese respondents, however, their level of concern stays around 4.6-4.8 (at the level between ‘neutral’ and ‘somewhat agree’).

The results of our studies clearly highlight an important cultural difference. That is, Japanese who seek hedonistic experiences expressed their concern about their local community becoming a hotspot of infectious diseases caused by inbound tourism, whereas Danes and Italians who seek hedonistic experiences were less concerned about this issue, as for the Summer 2020. This difference could be explained by the so-called “independent self-schema” typically held by Westerns (Europeans) and the “interdependent self-schema” typically held by Far East Asians.

In other words, Danes and Italians who are typically based on an “independent self-schema” would realize the “positivity of the personal self” through their pleasure-seeking behaviors. In such a scenario, they would be less concerned about their local community becoming a hotspot of infectious diseases. On the other hand, Japanese who are typically based on an “interdependent self-schema” would consider a balance among different selves in their in-group relationship important and prioritize the protection of their in-group communities. The survey results presented in Glückstad et al. (2021) and the adverse reaction by Japanese to the recent Japanese opinion surveys about being host of the Olympic Games in Tokyo are good examples of such protective attitudes identified in the society based on the interdependent self-schema.
