Signaling Quality Through Specialization
Marketing Science, 2008Firms frequently position themselves as specialists. An implication of specialization is that the firm has forgone alternative opportunities. In the context of effort-intensive categories, we show that a firm can signal quality to consumers by specializing. In the model, a firm must decide to provide one service offering or to market two services.

On the quality assessment of sound signals
2008 IEEE International Symposium on Circuits and Systems, 2008This paper constitutes an introduction to the field of quality evaluation of sound (speech and audio) signals. The need for such an assessment is inherent to modern communications: VoIP, mobile phone, or teleconference systems require meaningful measures of performance, which may ultimately assure good service or profitable business.

Quality Signaling through Crowdfunding Pricing
SSRN Electronic Journal, 2020Problem definition: This paper studies an entrepreneur’s pricing strategy in a reward-based crowdfunding campaign under asymmetric product quality information. We propose two signaling mechanisms and investigate how entrepreneurs can leverage their pricing strategy to signal a high-quality project.

Chloroplast signaling and quality control
Essays in Biochemistry, 2017Although chloroplasts contain their own genetic system and are semi-autonomous cell organelles, plastid biogenesis and homeostasis are heavily dependent on the nucleo-cytosolic compartment. These two cellular compartments are closely co-ordinated through a complex signaling network comprising both anterograde and retrograde signaling chains ...

On the effects of motion on the quality of pal signals
1993 IEEE International Symposium on Circuits and Systems, 2002The relationships between motion and television signal deterioration are explored for one of the two television coding schemes currently most used, i.e., PAL. The relevance of motion issues is related to the fact that, to a given extent, for PAL and NTSC (and in general for fixed bit-rate image coding schemes), television signals quality becomes worse ...

Prices as Signals of Product Quality
The Review of Economic Studies, 1983This paper is concerned with the provision of quality in markets in which consumers have only imperfect information. The analysis focuses on a market for a product that can be produced at different quality levels. All consumers prefer higher to lower quality, but they may differ in their willingness to pay for quality. Producers can produce any quality

Signal quality of resting electrocardiograms
Journal of Electrocardiology, 1983Artifact may cause errors of technical origin when ECGs are interpreted by automatic methods. Baseline shift and high-frequency noise content of minimal and typical length ECG records from pediatric and adult populations were measured to allow prediction of both the likelihood of interpretation errors of technical origin and the number of reacquistions

An Overview of Signal Quality Indices on Dynamic ECG Signal Quality Assessment
2020With the rapid development of wearable ECG medical devices, it is an imperious demand to evaluate the quality of dynamic ECG signals. Thus, a lot of signal quality indices (SQIs) have been proposed in the past few years. In this chapter, we review the analysis performances of SQIs from time-domain, frequency-domain, joint time-frequency, self ...

PLANNED OBSOLESCENCE AS A SIGNAL OF QUALITY
International Economic Journal, 2001This paper provides a new rationale for planned obsolescence based on imperfect information about the quality of durable goods. The source of the inefficient choice of durability lies in the fact that the frequency of repeat purchases and the future expected profit that can monitor the quality of the good is inversely related to the durability of the ...

European Journal of Political Economy, 1993
Abstract This paper discusses non-cooperative equilibrium notions that have recently been applied in the analysis of signalling games. As an illustration, we analyse the role of prices as signals when consumers are incompletely informed about product quality before purchase.
