We model the availability of product information in Internet-based markets, and explain the underlying causes for the phenomenon of less than perfect information available to consumers of products and services in these markets. We use Salop’s model of product differentiation and explore the conditions under which sellers make horizontal information available to buyers. We demonstrate that under...

The Internet revolution brought about significant changes in the availability of market information to consumers in many industries. This research examines technology-driven changes in market transparency, defined as the ability of market participants to observe information about products and prices. The objective is to develop a modeling and empirical basis for a theory of market transparency ...

introduction preterm infants are exposed to irregular light for several weeks or months in the neonatal intensive-care unit (nicu). this lack of maternal entrainment, the exposure to irregular extrauterine lighting and care in the nursery may contribute to the disturbances in body temperature, sleep and physiological changes that are commonly experienced by preterm infants. materials and method...

night work can have a significant impact on health, well-being, performance and occupational safety of workers. night workers often complain about the sleep disorder characterized by excessive sleepiness.  the aim of the study was to determine the level of sleepiness among night workers and investigate its relationship with oral temperature in a hot industry. this cross-sectional study involved...

Civil aviation operators have expressed an increased interest in conducting night operations with night vision imaging systems. The development of special operational concepts, hardware requirements, training requirements, and regulatory change and oversight is necessary to control for the known performance constraints associated with these devices. In 2001, the Aerospace Medical Association in...

The Trading Agent Competition (TAC) is an open-invitation forum designed to encourage research into electronic markets and trading agents. In this paper we present the Socrates trading agent and the strategies that were developed for and used in the TAC Supply Chain Management game as part of the 2004 competition. The resulting behaviour and performance in the TAC competition as well as in a se...

In this paper, we extend field experiments of real money prediction markets to the problem of forecasting the success of a new product. We collect forecasts using a traditional survey mechanism and a market mechanism. Our results suggest that market prices summarize the information contained in survey forecasts and improve those forecasts by reducing the variability of the forecast. However, we...

Abstract This paper presents and discusses a number of criteria for the design and implementation of electronic market servers. It first briefly reviews a number of electronic markets currently operational over the internet then offers some ideas on the types of new markets that may become successful. It then presents the design criteria for market servers, necessary to support these virtual ma...

With the advent of the Internet, we have seen existing markets transform and new ones emerge. In this paper, we contribute to the understanding of this phenomenon by theorizing about the role that IT plays in affecting market information, transparency and market structure. In particular, we introduce a new theoretical framework which uncovers the process and the forces that, together with IT, f...
