This paper analyzes an infinite-period oligopoly model where consumers incur costs when switching supplier. Every period only a fraction α of consumers considers switching. Firms can price-discriminate between their current customers and consumers who did not buy from the firm in the past period. In this setting, firms set relatively low introductory prices to attract new consumers. Contrary to...

When new technology is introduced through an upgrade from or a replacement of an existing system, switching costs can be an important factor influencing the adoption of the new system. Recent research has identified several categories of switching costs including: uncertainty costs, emotional costs, learning costs, reduced performance costs, and sunk costs. A substantial amount of literature su...

We give a geometric proof of a “parity-switching” phenomenon that occurs when applying the local Langlands and Jacquet–Langlands correspondence to a self-dual supercuspidal representation ofGL(n) over a nonarchimedean local field. This turns out to reflect a duality property on the self-dual part of the `-adic étale cohomology of the Lubin–Tate tower.

Customers could switch service provider easily because of lower searching cost and identical service in online environment. Most marketing research for customer loyalty emphasizes the effect of satisfaction and switching barrier, derived from investment model. However, how satisfaction and switching barrier influence customer loyalty has been less conclusive. The possible reason is neglect of c...

I investigate the e¤ects of switching costs on the market outcome in network industries using a dynamic duopoly model of price competition in the presence of an outside option. I …nd that the role of switching costs depends on network e¤ects and the outside option. Without a viable outside option, high switching costs can neutralize the tendency towards high market concentration associated with...

Introductory Offers in a Model of Strategic Competition* We show how introductory offers emerge endogenously under conditions of competition in markets with switching costs. In a standard Hotelling model we find the combination of switching costs and introductory discounts to reduce industry profits relative to industries without switching costs, in which introductory offers do not emerge. Thus...

We discuss certain general features of the pentaquark picture for the θ, its 10F partner, Ξ3/2, and possible heavy quark analogues. Models employing spin-dependent interactions based on either effective Goldstone boson exchange or effective color magnetic exchange are also used to shed light on possible corrections to the Jaffe-Wilczek and KarlinerLipkin scenarios. Some model-dependent features...

Our overall goal is to develop and qualify devices capable of repetitively switching high peak currents (>1 MA) and large quantities of charge (>500 C). In 1988 we designed and tested a hollow-anode ignitron at levels of up 925 kA and 280 C per shot[1]. This level is three times that previously achieved with standard, commercially available tubes[2]. Our latest designs, developed with the coope...

There is a systematic relationship between stress accent and vocalic identity in spontaneous English discourse (the Switchboard corpus of telephone dialogues). Low vowels are much more likely to be fully accented than their high vocalic counterparts. And conversely, high vowels are far more likely to lack stress accent than low or mid vocalic segments. Such patterns imply that stress accent and...
