As firms continue to abandon pensions in favor of employee-managed retirement plans, tremendous demands are being placed on the decision-making proficiency of future retirees. As reflected in the equity premium puzzle, individual investors tend to hold overly conservative portfolios that provide...

It is commonly believed that the user's cognitive style should be considered in the design of Management Information Systems and Decision Support Systems. In contrast, an examination of the literature and a consideration of some of the broader issues involved in MIS and DSS design lead to the...

Commercially available tracking systems based on advanced communications and computing technology allow a dispatcher of hazardous material transports to monitor the movement of vehicles on a transportation network in real time. When unexpected events occur, a dispatcher working with this new...

Human blood is a perishable product: in the U.S. it has a legal lifetime of 21 days from collection, during which it can be used for transfusion to a patient of the same type, and after which it has to be discarded. It is collected in units of one pint from volunteer donors at various collection...

When using a decision support system (DSS) containing a large model base, a user has to decide which specific models are relevant for any particular task. When the model base is large and diverse, this task can be quite difficult. Furthermore, the number and variety of models available can be...

Marketing decision makers are confronted with an increasing amount of information. This leads to a complex decision environment that may cause decision makers to lapse into using mental-effort-reducing heuristics such as anchoring and adjustment. In an experimental study, we find that the use of...

The development of the information systems (IS) literature in Management Science during the past 50 years reflects the inception, growth, and maturation of several different research streams. The five research streams we identify incorporate different definitions of the managerial problems that...

Decision models are often based on certain assumptions as to their validity. Relevant assumptions may include value-based assumptions, such as limitations on the range or values of some input variables or exogenous factors, as well as assumptions about model structure (e.g., linearity). In a...

A decision maker's performance relies on the availability of relevant information. In many environments, the relation between the decision maker's informational needs and the information base is complex and uncertain. A fundamental concept of information systems, such as decision support and...

Despite the increasing popularity of decision support systems (DSS), effectiveness of such systems remains unproven. Past research claiming usefulness of the DSS has relied largely on anecdotal or case data. The relatively few laboratory experiments report mixed results regarding the effects of...
