Weber's law has important applications in marketing. Manufacturers and marketers endeavor to determine the relevant JND for their products for two very different reasons: so that negative changes (e.g. reductions in product size or quality, or increase in product price) are not discernible to the public (i.e. remain below JND) and
Both Weber's law and Fechner's law were formulated by Gustav Theodor Fechner (1801–1887). They were first published in 1860 in the work Elemente der Psychophysik ( Elements of Psychophysics ). This publication was the first work ever in this field, and where Fechner coined the term psychophysics to describe the interdisciplinary study of how ...
A supply is a good or service that producers are willing to provide. The law of supply determines the quantity of supply at a given price. [5]The law of supply and demand states that, for a given product, if the quantity demanded exceeds the quantity supplied, then the price increases, which decreases the demand (law of demand) and increases the supply (law of supply)—and vice versa—until ...
His experiments were intended to determine the absolute and difference, or differential, thresholds. Weber was able to define absolute and difference threshold statistically, which led to the establishment of Weber's Law and the concept of just noticeable difference to describe threshold perception of stimuli.
The two-point threshold, the smallest distance between two points where a person determines that it is two points and not one, was Weber’s first discovery. Weber’s work made a significant impact on the field of experimental psychology , as he was one of the first scientist to test his ideas on humans.

Weber states that, "the minimum increase of stimulus which will produce a perceptible increase of sensation is proportional to the pre-existent stimulus," while Fechner's law is an inference from Weber's law which states that the intensity of our sensation increases only as the logarithm of an increase in energy rather than as rapidly as the ...
The law of demand applies to a variety of organisational and business situations. Price determination, government policy formation etc are examples. [6] Together with the law of supply, the law of demand provides to us the equilibrium price and quantity. Moreover, the law of demand and supply explains why goods are priced at the level that they ...
