Leadership and group size: An experiment

Our experimental results suggest that the effectiveness of leading by example decreases with group size. The discrepancy between the leaders' and followers' incentives increases with group size. Thus, as group size increases, followers more often refuse to follow their leaders.

What happened with the grandiose plans? Strategic plans and network realities in B2B interaction

Research concerned with business relationships and organizational levels, respectively, has addressed companies' difficulties in realizing their strategies. Studies of business relationships explain this through actions and reactions among business partners. Organizational studies note gaps between strategic and operational organizational levels in perceptions and goals. This paper combines these perspectives to obtain new insights into why company strategies may not materialize. The purpose of this paper is to describe and discuss how actor bonds on various organizational levels in business relationships affect strategy realization. The paper shows that actors on similar organizational levels representing different companies may actually share more understandings and activities than actors within the same company. The paper contributes to research on dyadic business relationships by highlighting differences in perspectives on various organizational levels, adds insights into research studying organizations by including a business-relationship aspect, and increases understanding of why strategic plans sometimes fail to succeed.     

Risk preference heterogeneity in group contests

We analyze the first model of a group contest with players that are heterogeneous in their risk preferences. In our model, individuals’ preferences are represented by a utility function exhibiting a generalized form of constant absolute risk aversion, allowing us to consider any combination of risk-averse, risk-neutral, and risk-loving players. We begin by proving equilibrium existence and uniqueness under both linear and convex investment costs. Then, we explore how the sorting of a compatible set of players by their risk attitudes into competing groups affects aggregate investment. With linear costs, a balanced sorting (i.e., minimizing the variance in risk attitudes across groups) always produces an aggregate investment level that is at least as high as an unbalanced sorting (i.e., maximizing the variance in risk attitudes across groups). Under convex costs, however, identifying which sorting is optimal is more nuanced and depends on preference and cost parameters.

Comparing face-to-face meetings, nominal groups, Delphi and prediction markets on an estimation task

We conducted laboratory experiments for analyzing the accuracy of three structured approaches (nominal groups, Delphi, and prediction markets) relative to traditional face-to-face meetings (FTF). We recruited 227 participants (11 groups per method) who were required to solve a quantitative judgment task that did not involve distributed knowledge. This task consisted of ten factual questions, which required percentage estimates. While we did not find statistically significant differences in accuracy between the four methods overall, the results differed somewhat at the individual question level. Delphi was as accurate as FTF for eight questions and outperformed FTF for two questions. By comparison, prediction markets did not outperform FTF for any of the questions and were inferior for three questions. The relative performances of nominal groups and FTF were mixed and the differences were small. We also compared the results from the three structured approaches to prior individual estimates and staticized groups. The three structured approaches were more accurate than participants’ prior individual estimates. Delphi was also more accurate than staticized groups. Nominal groups and prediction markets provided little additional value relative to a simple average of the forecasts. In addition, we examined participants’ perceptions of the group and the group process. The participants rated personal communications more favorably than computer-mediated interactions. The group interactions in FTF and nominal groups were perceived as being highly cooperative and effective. Prediction markets were rated least favourably: prediction market participants were least satisfied with the group process and perceived their method as the most difficult.

消费者对安全认证农产品的购买意愿与行为分析—基于长沙市的调查数据

以长沙市消费者的调查数据为例,剖析了长沙市消费者对安全认证农产品的认知情况、接受意愿、支付意愿和实际的购买行为及其相关影响因素。结果表明：消费者对农产品质量安全的关注程度较高,但对安全认证农产品的认知程度较低、信任度较低。消费者的收入水平、消费者对安全农产品的认知程度、受教育水平以及对政府的信任等均会不同程度地影响消费者对安全认证农产品的购买意愿与行为。
