Cost-of-production theory of value
The cost-of-production theory of value is the belief that the value of an object is decided by the resources that went into making it.The most common counterpoint to this is the marginal theory of value which asserts that economic value is set by the consumer's marginal utility. This is by far the more widely accepted view in modern economics.
Two of the most common cost-of-production theories are the medieval just price theory and the classical labor theory of value. The labor theory of value is still subscribed to by most Marxist economists.
