ExpertLens: A system for eliciting opinions from a large pool of non-collocated experts with diverse knowledge

The complexity of policy decision-making raises the need to elicit opinions from large and heterogeneous groups of stakeholders with broad and diverse sets of expertise. Existing options for elicitation include small face-to-face panels of experts by using the Nominal Group Technique (NGT), large Delphi panels whose members do not interact with each other face-to-face, and crowdsourcing, which involves an open call for input issued to a large community of people. In an attempt to close the gap between the practical needs of policy makers and the methodological challenges associated with eliciting opinions of large, diverse, and distributed groups, we have developed a new online elicitation system and methodology called ExpertLens. By optimizing the direct interactions of NGT with the larger number of Delphi participants and the wisdom of “selected crowds,” our approach is designed to save on the costs associated with traditional expert panels, while increasing accuracy in elicitation by reducing the potential for group process losses that can occur in large, diverse, and non-collocated panels whose members interact via asynchronous online discussion boards. The ExpertLens approach is iterative, does not require participants to develop consensus, and determines what the group “thinks” by statistically analyzing data collected in all rounds of the elicitation. This paper describes the ExpertLens system and methodology, briefly discusses recent ExpertLens trials, provides conceptual arguments for why it is an appropriate model for eliciting expert opinions, illustrates its main components and analytics by using an infrastructure investment example, and discusses a research agenda for testing the underlying tenets of the ExpertLens approach.     

Reciprocity in Caring Labor: Nurses’ Work in Residential Aged Care in Australia

Feminist economists identify reciprocity as a motivation for both paid and unpaid caring work. In general, reciprocity describes people responding to each other in similar ways, either benevolently or harmfully. The quality of care is potentially increased when care relationships are motivated by positive and generalized forms of reciprocity and decreased with negative forms of reciprocity. This study draws on nursing literature and two qualitative studies in Australian residential aged care facilities, conducted in 2002–3 and 2009, to identify a new form called “professional reciprocity.” This form of reciprocity involves deliberate and skilled relational work by nurses to facilitate mutual and interdependent exchanges with care recipients that are beneficial to both care recipients and nurses. This study argues that professional reciprocity, as a skill that can be taught, is important for achieving quality care and workers’ job satisfaction.     

CEO turnover and bondholder wealth

We examine the impact of CEO turnover announcements on bondholder wealth, stockholder wealth, and overall firm value. Using publicly traded data for the period from 1973 to 2000, we find evidence consistent with both the wealth transfer and signaling hypotheses. Specifically, we find that CEO turnover events are associated with lower bondholder values, higher stockholder values, and that net changes in firm value are a function of turnover type (forced vs voluntary and outside vs inside firm replacements) and the riskiness of the firm’s debt (investment vs non-investment grade). Overall, the results contribute to the understanding of the effects of corporate governance mechanisms, of which CEO turnover is an extreme form, on bondholders.     

Why statutory union recognition is bad labour policy:the North American experience

The proposed British legislation is modelled on that of the United States which has been a clear failure in its stated goal of encouraging the practice and procedure of collective bargaining (Adams, 1993). It has instead perpetuated a culture of labour-management animosity that many other nations have 113been able, to their benefit, to overcome (Adams, 1995c).     

Does corporate international diversification destroy value? Evidence from cross-border mergers and acquisitions

This paper investigates the valuation effects of corporate international diversification by examining cross-border mergers and acquisitions of US acquirers over the period 1990–2000. We find that, on average, acquisitions of “fairly valued” foreign business units do not lead to value discounts. In contrast, unrelated cross-border acquisitions result in a significant diversification discount of about 24% after accounting for the valuation of foreign targets. Furthermore, significant wealth gains accrue to foreign target shareholders regardless of the type of acquisition. Overall, our results suggest that international diversification does not destroy value while industrial diversification leads to discounts even after controlling for the pre-acquisition value of the target.
