This article reviews the purchase behaviour of consumers for plants and the attitude towards horticultural novelties. The palm, Trachycarpus wagnerianus especially, is the main focus of this study. Based on a survey of 408 customers in Bavaria during autumn 2009, the results gave an impression of how consumers inform themselves about novelties in horticulture as well as, their attitude to T. wa...

The notion of concordance is central to many multiple criteria techniques relying on ordinal information, e.g. outranking methods. It leads to compare alternatives by pairs on the basis of a comparison of coalitions of attributes in terms of “importance”. This note proposes a characterization of the binary relations that can be obtained using such comparisons, within a general framework for con...

In this paper we explore which bundles of services are attractive to users. We look specifically into bundle composition with navigation services as core, and travel and entertainment related services as complementary services. Pricing is an important criterion as well. We use conjoint measurement as a tool to assess which combination of services and price is the most attractive for users. We f...

This paper studies an extension of biorders that has a “frontier” between the relation and the absence of relation. This extension is motivated by a conjoint measurement problem consisting in the additive representation of ordered coverings defined on product sets of two components. We also investigate interval orders and semiorders with frontier.

Conjoint analysis as a commercial method has been available for more than 20 years (Green, Wind and Jain 1972). Ten years ago, 1987, at a Sawtooth conference, I raised the question of how conjoint could work so well, given obvious differences between the task and market choice. I proposed that conjoint works primarily because the simplification in a conjoint task mirrors the simplification in t...

Survey experiments are a core tool for causal inference. Yet, the design of classical survey experiments prevents them from identifying which components of a multidimensional treatment are influential. Here, we show how conjoint analysis, an experimental design yet to be widely applied in political science, enables researchers to estimate the causal effects of multiple treatment components and ...

Conjoint couples treatment for interpersonal partner violence (IPV) remains controversial despite a growing body of research and practice experience indicating that it can be effective and safe. In addition, developing typologies of couples who are violent suggest that a "one-size-fits-all" treatment approach to IPV is not appropriate and conjoint treatment may have a place in the treatment of ...

The empirical study of the axioms underlying additive conjoint measurement initially focused mostly on the double cancellation axiom. That axiom was shown to exhibit redundant features that made its statistical evaluation a major challenge. The special case of double cancellation where inequalities are replaced by indifferences – the Thomsen condition – turned out in the full axiomatic context ...
