Implications of Negotiation Theory for Research and Development of Negotiation Support Systems

Group Decision and Negotiation, 1997

This paper summarizes a parametric theory of negotiation as a basis forshedding light on negotiation support system possibilities. Previously, thetheory has been used to analyze prior research accomplishments in the area ofnegotiation support systems. Here, we discuss implications of the theory thatare relevant for future research and development of negotiation supportsystems. The implications are concerned with three topics: a high-levelgeneric characterization of these systems, an identification of theirpossible support functions, and a taxonomy for classifying suchsystems.

Insensitivity to the Value of Human Life: A Study of Psychophysical Numbing

Journal of Risk and Uncertainty, 1997

A fundamental principle of psychophysics is that people's ability to discriminate change in a physical stimulus diminishes as the magnitude of the stimulus increases. We find that people also exhibit diminished sensitivity in valuing lifesaving interventions against a background of increasing numbers of lives at risk. We call this psychophysical numbing. Studies 1 and 2 found that an intervention saving a fixed number of lives was judged significantly more beneficial when fewer lives were at risk overall. Study 3 found that respondents wanted the minimum number of lives a medical treatment would have to save to merit a fixed amount of funding to be much greater for a disease with a larger number of potential victims than for a disease with a smaller number. The need to better understand the dynamics of psychophysical numbing and to determine its effects on decision making is discussed.

Increasing Risk: Some Direct Constructions

This article extends the classic Rothschild–Stiglitz characterization of comparative risk (“increasing risk”) in two directions. By adopting a more general definition of “mean preserving spread” (MPS), it provides a direct construction of a sequence of MPS's linking any pair of ...
