This article reports the findings of 2 studies that examined the effects of low price guarantees (LPG) in retail advertisements within the framework of signaling theory. Overall, an LPG in an ad resulted in higher value perceptions and shopping intentions. Findings also suggest that the effect of an LPG is likely to be moderated by other price cues such as reference prices and by the price image of the store. An LPG resulted in higher value perception and shopping intention when reference prices were low or absent, but lowered search intention in the presence of a high reference price. Additional findings suggest that intention to search for a better price was lower, particularly when an LPG was offered by a low price image store. For high price image stores, an LPG increased value perceptions and shopping intentions, while also increasing search intentions, indicating the possibility that LPGs can act as a double-edged sword in certain instances. Managerial and public policy implications are also noted.
This paper describes a multiscale analytical model of the lamellar structure and the biomechanical response of the Pacinian Corpuscle (PC). In order to analyze the contribution of the PC lamellar structure for detecting high-frequency vibrotactile (VT) stimuli covering 10 Hz to a few kHz, the model response is studied against trapezoidal and sinusoidal stimuli. The model identifies a few generalizable features of the lamellar structure which makes it scalable for different sizes of PC with different number of lamellae. The model describes the mechanical signal conditioning of the lamellar structure in terms of a recursive transfer-function, termed as the Compression-Transmittance-Transfer-Function (CTTF). The analytical results show that with the increase of the PC layer index above 15, the PC inner core (IC) relaxes within 1 ms against step compression of the outermost layer. This model also considers the mass of each PC layer to investigate its effect on the biomechanical response of the lamellar structure. The interlamellar spacing and its biomechanical properties along with the model response are validated with experimental data in the literature. The proposed model can be used for simulating a network of PCs considering their diversity for analyzing the high-frequency VT sensitivity of the human skin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
