Voting (CSR) initiatives may give consumers a vicarious warm glow. However, recent research suggests that consumers may expect to overpay when companies engage in CSR due to perceptions of price fairness. The implication that "doing good" carries a financial burden for businesses leads consumers to infer general price markups. This body of research cautions that corporate warm glows may be coupled with "cold prickles" of extra costs. There is also evidence that product warm glows may play a role in a process called "hedonic licensing", in which consumers who perceive a moral surplus subsequently allow themselves more leeway to make selfish purchases.
Capital Markets Inefficiency in sustainable investments Warm glow in the context of sustainable investments involves investors deriving a sense of satisfaction from their responsible
investment decision-making rather than from the actual impact. Private investors who engage in sustainable investments tend to rely on their emotions rather than adopting a calculated approach to evaluate the impact of their investment. Hence, utility stems from the prosocial act itself and, therefore, does not increase linearly with the level of impact. This implies that investors’
willingness to pay is insensible to the level of impact of an investment. The concept of warm glow stands in contrast to the conventional behavior outlined in
decision theory, often referred to as "
consequentialism", where the utility of prosocial investors is directly linked to the level of impact generated by their investments. Private investors showing warm glow behavior typically seek opportunities to prevent
climate change, leading to a higher
willingness to pay for investments with a sustainable impact than investments with no impact. Leveraging warm glow becomes important in attracting funds for sustainable investments, encouraging investors to integrate sustainability considerations into their financial decisions. However, there are drawbacks when investors prioritize optimizing their warm glow over maximizing impact. Companies are incentivized to engage in
greenwashing or "impact-washing", promoting "light green" could realign investors' emotional preferences with the quantitative level of impact of a financial product and incentivize firms to offer real "green" products.
Philanthropy Avoidance behaviors Common phenomena such as avoiding eye contact with beggars or adjusting one's route to avoid a solicitor may be explained using the warm glow model. One behavioral consequence of warm glow is strategic avoidance of giving opportunities. According to this hypothesis, individuals anticipate their warm glow upon identifying a future giving opportunity. Assuming a functional form that allows warm glow to be negative (driven by a
guilt of not giving), people may strategically and effortfully avoid giving situations. The strategic incentive is easily understood through the utility function U_i = U_{i}(x_{i},G,g_{i}), where the warm glow (g_i),is positive for a donation (joy of giving) and negative for not giving (guilt). For an agent who would suffer a disutility of giving at their desired level (g_i^*)because the
marginal utility of private expenditure (x_i)exceeds the marginal utility of warm-glow giving, they should prefer to give nothing (g_i^0).Because giving nothing may be associated with guilt, the utility of (g_i^0)will be negative. Therefore, for a rational agent who cannot justify giving, U_i(x_i,G,g_i^*) , can maximize their utility through avoiding a giving situation, effectively dropping the warm glow argument from their utility functions. Moral philosopher
Peter Singer mentions warm-glow givers in his 2015 book,
The Most Good You Can Do. Singer states that these types of donors "give small amounts to many charities [and] are not so interested in whether what they are doing helps others." He references "empathetic concern" and "personal distress" as two distinct components of warm-glow givers.
Inefficiency in charitable selection Warm glow may offer an explanation for some of the observed inefficiencies in charitable giving. For example, United States citizens directed more than 60% of their total charitable contributions to religious groups, education institutions, art organizations, and foundations in 2017; compared to under 7% in foreign aid. According to models of social justice and economic
QALYs, highlight the inefficiency of all philanthropy not used to combat global poverty, which offers the highest marginal return. == Criticisms ==
