Value is the result of the combined, conscious, and creative actions of caring, which promote sustainable prosperity. Despite its centrality in marketing theory, value is treated in the literature as a self-evident, abstract term denoting concepts as diverse as the desire to acquire goods or enjoy services, the benefits derived from using a product, the price of an object, or a customer’s contribution to business profits. This approach leads to amoral marketing decision-making focused on extracting value from stakeholders and accumulating it in the form of shareholder wealth. In this framework, the negative consequences of marketing actions for society and the natural environment are simply dismissed as externalities. This is not sustainable as it degrades the environment and increases wealth and human welfare disparities between individuals, groups, and societies. Drawing on conceptualisations of value from the fields of philosophy, semiotics, and economics, value is here defined as the result of the combined, conscious, and creative actions of caring which promote sustainable prosperity. As such, value is understood to be co-created by the interactions of various stakeholders and positioned as the link between individuals, companies, markets, society, and the natural environment. Marketing theory has traditionally viewed value creation and exchange as the result of dyadic interactions. The socioeconomic and technological milieu of the 21st century, however, creates a business ecosystem characterised by digitalisation, interconnectivity, and decentralisation which means that, the number of participants in value co-creation networks is increasing and potentially tending towards infinity. Consequently, marketing is reconceptualised as the values-driven mechanism for value formation, valuation, symbolism, exchange facilitation, and integration of the resources required for value co-creation and distribution aiming at contributing to sustainable prosperity. Virtuous marketers and mindful marketing practice can ensure the optimal use of resources and the maximisation and equitable distribution of welfare in the present without compromising the ability of future generations to continue to generate and enjoy value. Thus, by placing value at the centre of the business ecosystem, marketing contributes to sustainable prosperity.
