Private polling in elections and voter welfare

We study elections in which two candidates poll voters about their preferred policies before taking policy positions. In the essentially unique equilibrium, candidates who receive moderate signals adopt more extreme platforms than their information suggests, but candidates with more extreme signals may moderate their platforms. Policy convergence does not maximize voters' welfare. Although candidates' platforms diverge in equilibrium, they do not do so as much as voters would like. We find that the electorate always prefers less correlation in candidate signals, and thus private over public polling. Some noise in the polling technology raises voters' welfare.     

Hurdle and Latent Class Approaches to Serial Non-Participation in Choice Models

In repeated choice modelling studies, it is often the case that individuals always select the status quo option. Although this pattern may reflect considered choices, they may also be the result of alternative decisions about whether to participate in the choice process at all. Alternative methods of dealing with this behaviour, each with associated implications for estimates of economic values, are presented. In particular we consider the alternative strategies of excluding such individuals from the data, using hurdle models to explicitly model this group, and propose the use of latent class models to endogenously allow for different preference structures. An advantage of the latent class approach is that the form of the non-participation need not be defined in advance. These approaches are considered using UK choice experiment data on food choices where the attributes include genetic modification of food. The latent class approach reveals the presence of two forms of non-participation in the data. This paper draws work commissioned by UK Department of Environment Food and Rural Affairs (DEFRA). The views presented in this paper are those of the authors alone and should not be regarded as those of DEFRA or of individuals within DEFRA.

Procedural Instrumentality and Audit Group Judgment: An Exploration of the Impact of Cognitive Fallibility and Ability Differences

The issue of auditor judgment prowess and resultant decision-making success has been an important topic in the behavioral auditing area for many years and has generated a voluminous research literature. However, relatively little literature exists on how differences in individual group member cognitive heuristics (fallibility) and ability impact the group process, and are impacted upon by the group process. This issue is important since so much of audit firm decision-making has its origins in audit group deliberations (Hunton 2001). Accordingly, understanding circumstances that give rise to either more flawed (‘process losses’), or better (‘process gains’), group decision-making outcomes are important even though the literature generally recognizes the superiority of group over individual decision-making (e.g., Rich et al. 1997). The model developed here is intended to develop a better understanding of cognitive factors that impact positively or negatively on audit group process. We then develop a four stage model of group decision-making, during which the differing assets and liabilities (cognitive, ability, expertise) of audit group members are combined. The four stages are diversity, controvery, insight and resolution. These are then described at length.
