This study explores the leadership dynamics, conflict, and group cohesion during Roald Amundsen’s South Pole expedition, with a particular focus on the critical confrontation between Amundsen and Hjalmar Johansen. Through a dual-method approach that integrates Narrative and Thematic Analysis, the research delves into the diaries and autobiographical writings of key expedition members. The findings reveal that while Amundsen’s authoritative leadership was pivotal to the expedition’s success, it also fostered significant internal conflict, particularly with Johansen. This tension highlights the delicate balance between decisive leadership and the need for inclusiveness in high-stakes environments. The study provides a nuanced understanding of how varying levels of loyalty among team members influenced group dynamics, offering insights that extend beyond the historical context of polar exploration to contemporary leadership challenges in extreme conditions.

Leadership mechanisms provide a potential means to mitigate social dilemmas, but empirical evidence on the success of such mechanisms is mixed. In this paper, we explore the institutional frame as a relevant factor for the effectiveness of leadership. We compare subjects’ behavior in public-goods experiments that are either framed positively (give-some game) or negatively (take-some game). We observe that leader and follower decisions are sensitive to the institutional frame. Leaders contribute less in the take-some game, and the correlation between leaders’ and followers’ contribution is weaker in the take-some game. Additionally, using a strategy method to elicit followers’ reactions at the individual level, we find evidence for the malleability of followers’ revealed cooperation types. Taken together, the leadership institution is found to be less efficient in the take- than in the give-frame, both in games that are played only once and repeatedly.

We experimentally study ways in which social preferences affect individual and group performance under indefinitely repeated relative incentives. We also identify the mediating role that communication and leadership play in generating these effects. We find other-regarding individuals tend to depress efforts by 15% on average. However, selfish individuals are nearly three times more likely to lead players to coordinate on minimal efforts when communication is possible. Hence, the other-regarding composition of a group has complex consequences for organizational performance.

March 11, 2021 marked the tenth anniversary of Japan’s triple disaster of 2011. Residents of Fukushima towns which endured the greatest environmental, social, and economic impact of the Fukushima Daiichi NPP accident have lived with uncertainty about the future for a full decade. Major infrastructure projects are fully or nearly complete, and decontamination efforts in reopened towns have largely concluded. Nevertheless, evacuee return rates have been low in most towns which had been placed under full evacuation orders. As a result, the current populations of many affected towns are less than 20% of their pre-disaster levels, and the majority of current residents over 65 years of age. Despite the huge challenges, the energy and know-how of the people of Fukushima are tremendous resources. Many see the possibility of new forms of long-term viability that capitalize on technology, the age of the population, and the ready availability of land and other resources. What has been achieved so far in realizing these visions has been made possible by an emergent network of informal community leaders, who display a charismatic, soft leadership style.

We conduct a laboratory experiment to study how, after a history of decay, cooperation in a repeated voluntary contribution game can be revived in an enduring way. Simply starting the repeated game over—a simple fresh start—leads to an initial increase of cooperation, but to a subsequent new decay. Motivated by cooperation decay in organizations we study the potential of three interventions of triggering higher and sustained cooperation, which take place at the same time as a restart. Surprisingly, we find that the detailed explanation of the causes of the decay in cooperation of Fischbacher and Gächter (Am Econ Rev 100:541–556, 2010) combined with an advice on how to prevent decay do not have an effect beyond that of just starting over. In contrast, a one-way free form communication message sent by the leader to the followers strongly revives cooperation. We find evidence that repeated free form communication by the leader further strengthens the reviving effect on cooperation. Combining the two previous interventions does not outperform the pure effect of communication. Our content analysis reveals that leader communication is more people oriented than the expert advice.

We study how the heterogeneity of agents affects the extent to which changes in financial incentives can pull a group out of a situation of coordination failure. We focus on the connections between cost asymmetries and leadership. Experimental subjects interact in groups of four in a series of weak-link games. The treatment variable is the distribution of high and low effort cost across subjects. We present data for one, two and three low-cost subjects as well as control sessions with symmetric costs. The overall pattern of coordination improvement is common across treatments. Early coordination improvements depend on the distribution of high and low effort costs across subjects, but these differences disappear with time. We find that initial leadership in overcoming coordination failure is not driven by low-cost subjects but by subjects with the most common cost type. This conformity effect may be due to a kind of group identity or to the cognitive simplicity of acting with identical others.

Leadership emergence is fraught with pervasive gender stereotypes, and women remain underrepresented in senior leadership roles, particularly in healthcare organisations. We apply ecological systems theory to explain how environmental factors enable or inhibit women’s leadership emergence in healthcare settings. We interviewed 17 senior female leaders in the Australian healthcare sector to explore how gender-related perceptions affected their leadership journeys. Five themes emerged that challenge existing narratives: men supported women’s advancement; women impeded other women’s progress; vulnerability was a leadership strength; ambitious women were ostracised; and women were ‘given’ leadership opportunities rather than actively pursuing them. By situating these findings within the ecological systems theory framework, we highlight the interplay of individual and contextual influences across ecosystem levels. Our study offers a novel perspective on gender stereotypes in leadership emergence, advancing ecological systems theory by extending it into a new field. We provide recommendations at individual, organisational, community, and societal levels to empower women leaders.

We study the effect on coordination in a minimum-effort game of a leader’s gender depending on whether the leader is democratically elected or is randomly selected. Leaders use non-binding messages to try to convince followers to coordinate on the Pareto-efficient equilibrium. We find that teams with elected leaders coordinate on higher effort levels. Initially, the benefits of being elected are captured solely by male leaders. However, this gender difference disappears with repeated interaction because unsuccessful male leaders are reelected more often than unsuccessful female leaders.
