They are often broader in scope than the theories of value of Adam Smith, David Ricardo, John Stuart Mill, Karl Marx, etc.
Marcel Mauss and Bronisław Malinowski for example wrote about objects that circulate in society without being consumed.
Bruce Owens talks about objects of value that are neither circulating nor consumed (e.g. gold reserves, warehoused paintings, family heirlooms).
For example, writing might be treated as the production of material for someone to consume through reading, and might be performed for some return in value (such as prestige).
For example, window shoppers can be seen as consuming a product by spending attention on shop displays, which are produced by marketers.
