title: Incorporating context effects into a choice model

authors: Rooderkerk, Robert P.

subjects: context effects

abstract: The behavioral literature provides ample evidence that consumer preferences are partly driven by the context provided by the set of alternatives. Three important context effects are the compromise, attraction, and similarity effects. Because these context effects affect choices in a systematic and predictable way, it should be possible to incorporate them in a choice model. However, the literature does not offer such a choice model. This study fills this gap by proposing a discrete-choice model that decomposes a product’s utility into a context free partworth utility and a context-dependent component capturing all three context effects. Model estimation results on choice-based conjoint data involving digital cameras provide convincing statistical evidence for context effects. The estimated context effects are consistent with the predictions from the behavioral literature, and accounting for context effects leads to better predictions both in and out of sample. To illustrate the benefit from incorporating context effects in a choice model, the authors discuss how firms could utilize the context sensitivity of consumers to design more profitable product lines.

title: The influence of the Amalgamated Metal Worker's Union (AMWU) on the New Zealand Engineer's Union (NZEU) with respect to the education and training reforms between 1987 and 1992

authors: Piercy, Gemma Louise

subjects: NZEU

abstract: In the 1980s the AMWU influenced the NZEU with respect to education and training.
The purpose of this study was to investigate the specific details of this relationship. It involved an extensive review of government policy documents and union literature. The study also involved twenty-three interviews in Australia and New Zealand. The findings confirmed and enhanced the previous observations about the influence of the AMWU. Not only did they identify in more depth the nature of the trans-Tasman influence; they also identified important similarities and differences between the contexts in which the two unions were operating. Specifically, the study found that whereas the AMWU had a long history and could be identified as pro-active; the NZEU came to education and training reform in response to labour market deregulation.
