An analysis of information overload with implications for survey design research

Abstract

A laboratory‐type experiment was conducted to examine potential information overload causes and solutions. It was found that both information quantity and information complexity are potential causes of information overload. The experiment results also suggested that information overload problems may be reduced through carefully designed information display patterns. When designing survey questionnaires, attention must be given to potential causes of information overload. Methods of presenting information that ameliorate information overload must also be considered. As demonstrated in this study, survey designs can be tested in controlled, laboratory‐type experiments. The results of these experiments can then be used to improve the design of field survey questionnaires.     

A Monopoly Classroom Experiment

The author uses a simple classroom experiment to develop the economic model of monopoly. As a pedagogical tool, the experiment introduces students to the nature of the monopoly problem and motivates them to think of the associated efficiency issues as a divergence between private benefits and social contributions. As a test of economic principles, the experiment highlights the role of information and fairness ideals in determining economic outcomes.     

Disaster‐Relief Logistics With Limited Fuel Supply

Disaster‐relief logistics consists of providing adequate emergency supplies rapidly to the affected people so as to minimize human suffering and death. This study empirically examines the impact that the shortage of fuel, a commonly encountered problem in many disaster situations, can have on the effectiveness of disaster‐relief logistics operations. We focus on investigating the following two issues: (1) whether the shortage of fuel is more damaging in attaining logistical goals than the equivalent‐sized shortage in emergency supplies themselves, and (2) what types of vehicles should be used when the fuel supply is limited. Results suggest that the shortage of fuel may be more damaging than the shortage of emergency supplies, and that smaller trucks may be preferred to larger trucks when the shortage of fuel becomes severe.

INDIVIDUAL AND ENVIRONMENTAL IMPACTS ON SUPPLY CHAIN INVENTORY MANAGEMENT: AN EXPERIMENTAL INVESTIGATION OF INFORMATION AVAILABILITY AND PROCEDURAL RATIONALITY

Some strategies for mitigating ordering inefficiencies in supply chains advise sharing information among decision‐makers. However, there has been little consideration of how individual perceptions intervene in the use of available information in decision‐making processes. This article reports the results of an experiment in which participants were instructed to minimize inventory holding and backlog costs for their supply chains as a whole. The analysis suggests that additional information affects supply chain inventory management costs only when rational decision‐making processes are followed. Decreased costs are observed when rational decision‐making is applied with backlog information. In contrast, increased costs are observed when consumer demand information is available.

Choice modelling with search and sort data from an interactive choice experiment

We present a highly structured, online, interactive choice environment containing a large number of alternatives, a search tool that eliminates alternatives that fail specified criteria, and a sort tool. A conceptual framework is developed that links tool usage and preference heterogeneity, and tested in the context of long-haul flight choice. Individuals who sort on price are more price sensitive; individuals who search on certain attributes have a greater marginal (dis)utility for that attribute; and individuals who perform certain non-price searches have a lesser price disutility. The method shows promise as a means for providing a richer picture of preference heterogeneity.
