Alarge body of research in economics, information systems, and marketing has sought to understand sources of price dispersion. Previous empirical work has mainly offered consumer- and/or product-based explanations for this phenomenon. In contrast, our research explores the key role played by vendors' price-format adoption in explaining price dispersion. We empirically analyze over a half-million online and offline prices offered by major U.S. airlines in the top 500 domestic markets. Our study shows that a vendor's price format remains an important source of price dispersion in both channels even after accounting for other factors known to impact dispersion in airline ticket prices. Importantly, this finding is true for both transacted and posted tickets. We document several other interesting empirical findings. First, the lower variance in the prices of "everyday low price" (EDLP) firms serves to reduce the market-level dispersion in prices when such firms are present. Moreover, the price variance of non-EDLP firms in these markets is also lower than in those markets in which EDLP competitors are absent. Second, we also find that dispersion in offered prices increases closer to the departure date, which is consistent with theoretical assertion that price dispersion increases with reservation prices. Finally, we continue to observe dispersion of online prices even after accounting for vendor strategy and other known sources of dispersion, suggesting that the prices are unlikely to converge even in the presence of sophisticated online search mechanisms.

Information and Computer Security aims to cover the human aspects of security, looking at the impact of user and business behaviours when dealing with security issues. It communicates fresh ideas and cutting-edge research to academics and practitioners.

The International Journal of Accounting Information Systems will publish thoughtful, well developed articles that examine the rapidly evolving relationship between accounting and information technology. Articles may range from empirical to analytical, from practice-based to the development of new techniques, but must be related to problems facing the integration of accounting and information technology. The journal will address (but will not limit itself to) the following specific issues: control and auditability of information systems; management of information technology; artificial intelligence research in accounting; development issues in accounting and information systems; human factors issues related to information technology; development of theories related to information technology; methodological issues in information technology research; information systems validation; human–computer interaction research in accounting information systems. The journal welcomes and encourages articles from both practitioners and academicians.Benefits to authorsWe also provide many author benefits, such as free PDFs, a liberal copyright policy, special discounts on Elsevier publications and much more.

IJADS promotes integration of functional and behavioural areas of business with concepts and methodologies of decision sciences and information systems, with explicit focus on modelling and applied decision-making. It offers practical guidance bridging the gap between theory and practice and draws on a wide range of disciplines, including accounting, decision sciences/management science, finance, information systems, marketing, operations/business process and strategic/organisational management. IJADS is the flagship journal of Alpha Iota Delta, the international honour society in decision sciences and information systems.

IJASS is dedicated to publishing quality manuscripts on all aspects of systemic analysis, from both a practical and an academic viewpoint. It publishes contributions from practitioners and academics, as well as national and international policy- and standard-making bodies, and sets out to be the definitive international reference source for such information.

The International Journal of Critical Infrastructure Protection (IJCIP) was launched in 2008, with the primary aim of publishing scholarly papers of the highest quality in all areas of critical infrastructure protection. Of particular interest are articles that weave science, technology, law and policy to craft sophisticated yet practical solutions for securing assets in the various critical infrastructure sectors. These critical infrastructure sectors include: information technology, telecommunications, energy, banking and finance, transportation systems, chemicals, critical manufacturing, agriculture and food, defense industrial base, public health and health care, national monuments and icons, drinking water and water treatment systems, commercial facilities, dams, emergency services, nuclear reactors, materials and waste, postal and shipping, and government facilities. Protecting and ensuring the continuity of operation of critical infrastructure assets are vital to national security, public health and safety, economic vitality, and societal wellbeing.The scope of the journal includes, but is not limited to:1. Analysis of security challenges that are unique or common to the various infrastructure sectors. 2. Identification of core security principles and techniques that can be applied to critical infrastructure protection.3. Elucidation of the dependencies and interdependencies existing between infrastructure sectors and techniques for mitigating the devastating effects of cascading failures.4. Creation of sophisticated, yet practical, solutions, for critical infrastructure protection that involve mathematical, scientific and engineering techniques, economic and social science methods, and/or legal and public policy constructs.A unique aspect of the journal is the publication of opinion pieces from leading international scholars and high-ranking government officials that tackle controversial issues related to critical infrastructure protection that are of global significance.The International Journal of Critical Infrastructure Protection is the official journal of International Federation for Information Processing (IFIP) Working Group 11.10 on Critical Infrastructure Protection.Benefits to authorsWe also provide many author benefits, such as free PDFs, a liberal copyright policy, special discounts on Elsevier publications and much more.

Many current data analysis techniques are beyond the reach of most managers and practitioners. Obscure maths and daunting algorithms have created an impassable chasm for problem solvers and decision makers. IJDATS bridges three gaps: firstly, a gap between academic ivory tower and the real world; secondly, a gap between quantitative data analysis techniques and qualitative data analysis techniques; and finally, a gap between a specific technique and an overall strategy.
