The increasing pervasiveness of social networks allows users to share purchase behaviors with their online friends. In the present study, we examine optimal pricing strategies of a monopolistic firm using an analytical model that accounts for behavioral observational learning in social networks....

We set up a game-theoretic model to examine the oligopolistic price competition, considering two features of online search: the existence of a common search ordering and shoppers who have non-positive search cost. We find that in equilibrium firms set their prices probabilistically rather than...

Procurement auctions are sometimes plagued with a chosen supplier's failing to accomplish a project successfully. The risk of project failure is considerable, especially when the buyer has inadequate information about suppliers ex ante and the project can only be evaluated at the end. To manage...

Online platforms are prone to abuse and manipulations from strategic parties. For example, social media and review websites suffer from sentiment manipulations, manifested in the form of opinion spam and fake reviews. The consequence of such manipulations is the deterioration of information...

The qualitative reasoning (QR) field has developed various representation and reasoning methods for the modeling with incomplete information or incomplete knowledge. While most uncertain reasoning approaches describe uncertain or imprecisely known information as probability distribution...

Shifts to more distributed forms of organizations and the prevalence of interorganizational relationships have lead to increasing needs for knowledge transfers between entities with asymmetric and incomplete information. Due to such information asymmetry and incompleteness, parties seeking...

We develop a system for grid computing where the price of computing tasks is determined by an audited market-exchange. We show a method to provide a variable certificate, called \witness," of program execution with the following property: If two different agents running the same program on the...

Millions of dollars change hands daily through online auction markets. However, fraud has been on the rise in these markets. Using a game theoretic approach, we propose a design of an economic incentive mechanism, the trusted third party (TTP), to serve the online auction communities. The...

Prior research has generated considerable knowledge on information systems design from software engineering and user-acceptance perspectives. As organizational processes are increasingly embedded within information systems, one of the key considerations of many business processes —...

This paper studies the strategic network formation in a location-based social network. We build an empirical model of social link creation that incorporates individual characteristics and pairwise user similarities. Specifically, we define four user proximity measures from biography, geography,...
