We present a game theoretic model for the availability of product information in Internet markets, where buyers can search for multiple products in parallel. We use a multiple-circle variation of Salop’s “unit circle” model of product differentiation where vendors are able to differentiate their products both horizontally (taste) and vertically (quality). We explore the conditions under which v...

Software vulnerability disclosure has generated intense interest and debate. In particular, there have been arguments made both in opposition to and in favor of alternatives such as full and instant disclosure and limited or no disclosure. An important consideration in this debate is the behavior of the software vendor. Does vulnerability disclosure policy have an effect on patch release behavi...

For instance, although street vendors are entrepreneurers, it is not always clear how or to what extent they value customers. Nor is it self-evident what kinds of service culture prevail in street vendors’ business, or how such culture supports service improve...

Neither customers will have the time, the ability or the endurance to work out the best deals with vendors, nor will vendors have time to bargain with every customer. In order for customers to st...

In the recent years, Software-as-a-Service has gained growing attention from software vendors as well as software customers. In this distribution and pricing model, software vendors are responsible for the operation and maintenance of solutions and customers pay for the service in form of continuous usage-based subscription fees. This study analyses the key characteristics of the Softwareas-a-S...

Cryptomarkets operate on the same model as eBay as they provide a platform where authorized vendors can set up a virtual shop and place listings. Building on a growing body of literature that seeks to understand cryptomarket participants, this paper seeks to explain the decision of cryptoma...

BACKGROUND Published studies of geocoding accuracy often focus on a single geographic area, address source or vendor, do not adjust accuracy measures for address characteristics, and do not examine effects of inaccuracy on exposure measures. We addressed these issues in a Women's Health Initiative ancillary study, the Environmental Epidemiology of Arrhythmogenesis in WHI. RESULTS Addresses in...
