Leadership Dynamics in Partially Distributed Teams: an Exploratory Study of the Effects of Configuration and Distance

Despite the importance of leadership and the wealth of empirical studies focused on leadership effectiveness in traditional and computer-supported groups, there is little research examining leadership dynamics in partially distributed virtual teams (PDTs). Virtual teams are partially distributed when they are configured with one or more subgroups of collocated members and isolated members. This paper lays the groundwork for an in-depth study of leadership in PDTs that can be extended to other types of virtual team configurations. Using three dimensions of virtual distance (geographic, cultural and temporal), we analyze how the configuration of virtual teams interacts with leadership dynamics. We also summarize the results of an exploratory study using 12 student teams to examine the effects of distance and configuration on leadership in PDTs. Findings show significant differences in leadership dynamics (i.e., leader emergence vs. leader retention) which impacted team performance. From these results, we develop propositions on leadership and PDTs.     

Turbulence in growing and declining industries

Turbulence over the industry life cycle is examined for the case of Portugal using the lowest possible level of industry aggregation, thus allowing for the use of panel data to study the evolution of product markets. Replacement of exiting firms by subsequent entrants plays a primary role in generating turbulence in high growth markets, while displacement of incumbents by recent entrants is the main selection force in declining markets. As the industry life cycle progresses, trial-and-error entry and entry mistakes decrease, and turbulence subsides.

TIME AND RECURSIVENESS IN LIVESTOCK FEEDING TRIALS*

In livestock feeding experiments the problem of recursiveness arises because the quantity of feed consumed by an animal is a function of its past history of feeding. The problem is most acute where experiments are designed to analyse sub ad lib feeding. The analysis of such experiments encounters two important problems. The first is that the actual quantity of feed consumed is an endogenous variable and is not directly under the control of the experimenter or the livestock producer. The second problem is the mathematical complexity of the relationships involved. A solution is suggested as a quasi reduced-form model.     

Flat Earth Economics: The Far-reaching Consequences of Flat Payoff Functions in Economic Decision Making

Economists tend to emphasize the optimum, but in many cases, even large deviations from optimal decisions make little difference to the payoff. This has far-reaching implications that are under-recognized, including: ( a ) decision makers often have a wide margin for error in their production planning decisions, and flexibility to pursue factors not considered in the calculation of payoffs; ( b ) optimizing techniques are sometimes of limited practical relevance for decision support; ( c ) the value of information used to refine management decisions is often low; and ( d ) the benefits of using "precision farming" technologies to adjust production input levels are often low.
