The sealed bidk-double auction is a mechanism used to structure bilateral bargaining under two-sided incomplete information. This mechanism is tested in two experiments in which subjects are asked to bargain repeatedly for 50 rounds with the same partner under conditions of information disparity favoring either the buyer (Condition BA) or seller (Condition SA). Qualitatively, the observed bid and offer functions are in agreement with the Bayesian linear equilibrium solution (LES) constructed by Chatterjee and Samuelson (1983). A trader favored by the information disparity, whether buyer or seller, receives a larger share of the realized gain from trade than the other trader. Comparison with previous results reported by Daniel, Seale, and Rapoport (1998), who used randomly matched rather than fixed pairs, shows that when reputation effects are present this advantage is significantly enhanced. A reinforcement-based learning model captures the major features of the offer and bid functions, accounting for most of the variability in the round-to-round individual decisions.  相似文献

In this paper, a social identity perspective on the management of diversity in organizations is outlined. The perspective is well‐placed to offer considerable insight in this area, given that it explicates the processes through which group memberships impact on people's attitudes and behaviour both within and between groups that are operative in the workplace. According to this perspective, relative group status and the perceived permeability of intergroup boundaries are key factors that need to be considered in any efforts to understand intergroup relations in the workplace. After a brief overview of the social identity perspective, the paper discusses: i) the role that group status and perceived permeability play in determining the nature of intergroup relations in the workplace, and 2) the type of interventions that can be derived from a social identity perspective in an effort to improve intergroup relations in the workplace.  相似文献

This paper explores a meta level question in process research: the implications of the move to a more market based mode of research now evident for the production of process knowledge. It first of all examines the implications for the changing organisation of process research. For example, there has been the emergence of a group of contract process researchers. These researchers may also form alliances with researchers from other disciplines within multidisciplinary teams. Second, it examines implications for the changing character of process knowledge in relation to criteria of internal and external validity. Different effects are evident at different stages at the research cycle, but it is argued that there is no inherent threat to concepts of validity. These trends are exemplified by a project on which the authors are currently engaged. The article concludes with a discussion about the possible future for process research.  相似文献

Samoa and its neighbouring Pacific Island Countries are highly vulnerable to climate change risks because their population and infrastructure are mostly located on low-lying coastal areas. Impacts of climate change are potentially disastrous to tourism, the major economic sector in the region. This research examines the conduciveness of the policy environment in Samoa for the tourism sector to adapt to climate change along three dimensions: stakeholders’ will and commitment, resources available, and policy-making mechanisms [Wong, E.P.Y., Mistilis, N., & Dwyer, L. (2011). A framework for analyzing intergovernmental collaboration – the case of ASEAN tourism. Tourism Management, 32, 367–376]. Samoa is used as an exemplar case study to understand how the Pacific island tourism sector can best adapt to climate change. It was found that the policy environment in Samoa is generally conducive. However, there is a strong need for closer public–private cooperation.  相似文献

This study extends research on psychological restoration by encompassing a broad set of restorative situations available to urban residents. Preferences are assessed for mundane restorative situations comprising leisure activity, setting, and social context, given different levels of attentional fatigue. Attentional fatigue, activity-setting, and social context were experimentally manipulated. The settings for activities were home, park, city center, and transit. Participants (N = 70) read scenarios describing an attentional state and rated their preference for the situations. Results show interactive effects of attentional state with activity-setting and with social context. The park was most preferred given attentional fatigue. Results confirm that while residents may particularly value urban nature for restoration, their urban context also provides other mundane but attractive restorative situations.  相似文献

ABSTRACT

In this article, we identify and describe the sequential order-of-entry problem. The sequential order-of-entry problem arises when, after having identified a desirable set of country markets to enter, firms are unable (because of budgetary constraints), or unwilling (because of possible learning or strategic issues), to enter all at once. The question then arises whether some sequences to entering the desirable set of country markets are better than others? Answering this question is shown to be nontrivial. The article outlines a number of arguments for the existence of superior sequences to entering a set of desirable country markets, and develops normative and dynamic frameworks to aid in the identification and evaluation of sequences.  相似文献

Prior literature suggests that the market underreacts to the positive correlation in a typical firm's seasonal earnings changes, which leads to a post‐earnings‐announcement drift (PEAD) in prices. We examine the market reaction for a distinct set of firms whose seasonal earnings changes are uncorrelated and show that the market incorrectly assumes that the earnings changes of these firms are positively correlated. We also document that positive (negative) seasonal earnings changes in the current quarter are associated with negative (positive) abnormal returns in the next quarter. Thus, we observe a reversal of abnormal returns, consistent with a systematic overreaction to earnings, rather than the previously documented PEAD. Additional analysis indicates that financial analysts similarly overestimate the autocorrelation of these firms, although to a lesser extent. We also find that the magnitude of overestimation and the subsequent price reversal are inversely related to the richness of the information environment. Our results challenge the notion that investors recognize but consistently underestimate earnings correlation and provide a new perspective on the inability of prices to fully reflect the implications of current earnings for future earnings. That is, we show that investors predictably overestimate correlation when it is lacking, but underestimate it when it is present.  相似文献

There have been repeated calls for a ‘new professionalism’ for carrying out agricultural research for development since the 1990s. At the centre of these calls is a recognition that for agricultural research to support the capacities required to face global patterns of change and their implications on rural livelihoods, requires a more systemic, learning focused and reflexive practice that bridges epistemologies and methodologies. In this paper, we share learning from efforts to mainstream such an approach through a large, multi-partner CGIAR research program working in aquatic agricultural systems. We reflect on four years of implementing research in development (RinD), the program’s approach to the new professionalism. We highlight successes and challenges and describe the key characteristics that define the approach. We conclude it is possible to build a program on a broader approach that embraces multidisciplinarity and engages with stakeholders in social-ecological systems. Our experience also suggests caution is required to ensure there is the time, space and appropriate evaluation methodologies in place to appreciate outcomes different to those to which conventional agricultural research aspires.  相似文献
