Detection threshold

In psychology, the lower limit from which a sensory organ perceives stimuli (the level at which an increase in a detected stimulus can be perceived). The word was transferred from there to the inflation perceived by consumers. In the course of this, it seems certain that the stimulus threshold is extraordinarily low even for very small price increases in the area of those goods – in other words, customers react to minute price changes – which are purchased on an ongoing, even daily basis. In the case of private households, these include above all foodstuffs and, for motorists (CH: Automobilisten), gasoline. Suppliers therefore try to avoid obvious, visible price adjustments necessitated by cost increases. They first seek other ways, such as changes in quality or, in the case of packaged goods, a reduction in weight. This, in turn, causes particular problems for official statistics and the central bank’s inflation measurement. – See banknote value restriction, inflation, perceived, ramp.
