Is economic value material or can it be psychological?

Economic value can be both material and psychological, depending on the context and perspective. In the traditional sense, economic value is often associated with tangible and measurable factors such as physical assets, goods, services, or resources. The psychological aspects of economic value are driven by individual or collective beliefs, preferences, and emotions. I think the next burst in economic growth will be driven by improvements in marketing efficiency, specifically resulting from in academic research in psychology, human behaviour, anthropology, and behavioural economics.
