Using data from 310 executive MBA students in 66 teams on a business simulation project, we explored (a) how shared leadership and team learning behaviors influence each other over time in self-managed teams, and (b) how the stability of the leadership network structure (i.e., network churn) is associated with team learning behaviors. We found that shared leadership stimulated team learning beh…
Extending past research showing that sequences of low cognitions (low-level processing of information) and high cognitions (high-level processing of information through questions and elaborations) influence the likelihoods of subsequent high and low cognitions, this study examines whether sequences of cognitions are related to group performance over time; 54 primary school students (18 …
Team learning is a complex social phenomenon that develops and changes over time. Hence, to promote understanding of the fine-grained dynamics of team learning, research should account for the temporal patterns of team learning behavior. Taking important steps in this direction, this special issue offers novel insights into the dynamics of team learning by advocating a temporal perspect…
This research explores the multilevel dual-mediation processes related to how leader other- emotion appraisal impacts employee turnover intention. Using a Taiwanese sample of 197 employees and their leaders in 64 work teams, the results revealed that leader other-emotion appraisal was positively related to leader positive emotion display and employee satisfaction with the leader. Moreove…
Crisis management teams face situations characterized by high risk, time pressure, and uncertainty and must adapt to a wide range of circumstances. Self-organizing teams have been proposed as an alternative to more traditional functional teams as they are described as adaptive and promptly reconfigurable. This study investigated whether self-organizing teams display more role flexibilit…
Group intervention has been widely used with female victims of intimate partner violence (IPV). However, efficacy studies are scarce due to several research limitations. This study evaluates the effectiveness of an 8-week group intervention program, with a cognitive- behavioral orientation and attended by 23 female victims of IPV. Self-report psychological assessment was conducted at pre…
Body movements, autonomic arousal, and electroencephalograms (EEGs) of group members are often coordinated or synchronized with those of other group members. Linear and nonlinear measures of synchronization have been developed for pairs of individuals, but little work has been done on measures of synchronization for groups. We define a new synchronization coefficient, SE, for a group ba…
Political parties in US politics are becoming increasingly polarized, with a growing number of extreme candidates entering electoral races. Why would extremists challenge more moderate opponents, since their chances of winning are supposedly very slim? I develop a model of electoral competition and endogenous entry to show that extremists rely on the possibility that the campaign might …
Our model describes competition between groups driven by the choices of self-interested voters within groups. Within a Poisson voting environment, parties observe aggregate support from groups and can allocate prizes or punishments to them. In a tournament style analysis, the model characterizes how contingent allocation of prizes based on relative levels of support affects equilibrium …
This paper presents a specific dynamic extension to the model outlined by Jackson and Morelli (Political bias and war. The American Economic Review 97(4): 1353–1373). In particular, we focus on the implications of a long-lived leader who possesses bias towards or against war that potentially differs from the country (s)he represents. Bargaining and war outcomes are characterized in this…
We model a procedural reform aimed at restoring a proper role for the minority in the confirmation process of judicial nominations in the US Senate. We propose that nominations to the same level court be collected in periodic lists and voted upon individually with storable votes, allowing each senator to allocate freely across the list a fixed number of total votes. Although each nomina…
Many regimes, particularly autocracies, hold elections where the ruling regime’s victory is a foregone conclusion. This paper provides a formal analysis of how these non-competitive elections affect citizen welfare compared to a non-electoral baseline. To do so, I first develop a game-theoretic framework that captures many extant theories of why regimes hold non- competitive elections, w…
Partisan voters are optimistic about electoral outcomes: their estimates of the probability of electoral success for their party are substantially higher than the average among the electorate. This has large potential implications for political bargaining. Optimistic electoral expectations make costly bargaining delay look more favourable, which may induce partisans to punish their part…
Why do elites in some authoritarian regimes but not others remove from power the leaders who harm their interests? We develop a formal theory explaining this. The theory shows how elites’ ambition prevents them from controlling authoritarian leaders. Because ambitious elites are willing to stage coups to acquire power even when the leader is good, ambition renders elites’ claims that th…
Observing substantial variations in Senate confirmation durations, existing studies have tried to explain when the Senate takes more or less time to confirm presidential nominees. However, they have largely ignored the president’s incentives to nominate someone who he expects will be delayed and do not specify conditions under which delay occurs. To improve on existing literature, I develop…
By incorporating electoral uncertainty and policy dynamics into three two-period models of the appointments process, we show that gridlock may not always occur under divided government, contrary to the findings of static one-shot appointments models. In these cases, contrary to the ally principle familiar to students of bureaucratic politics, the president or the confirmer is willing to…
The existence of authoritarian elections raises a number of questions regarding the strategies of political opposition. What explains the choice of strategy among key opponents of a regime? What determines when opposition groups willingly participate in elections and when they engage in electoral boycott? To understand the opposition’s strategic choices, we develop a formal model of gov…
The lion’s share of policy in the United States is made by administrative agencies. Agencies not only make policy choices, they must also implement policy effectively. Oversight institutions play an integral role in the policymaking process by monitoring, through review of agency policy actions, both policymaking tasks. Through analysis of a formal model I develop a theory of policymaking…
This paper considers an electoral model in which an incumbent and a challenger have ideological policy preferences that are private information. The incumbent may bias pre-electoral policies to signal preferences to the electorate with the aim of affecting the outcome of the election. When the two candidates are of completely different types, such a policy bias can occur only in a moder…
Why are judicial nominees allowed to refuse to answer questions about important issues that could come before the courts? We address this question by examining the information environment surrounding judicial nominations. Using the Supreme Court as our example, we formulate a model that departs from the existing literature by incorporating the fact that the Senate often does not know what…
