Effective leaders promote cooperation among their followers. Although many studies have focused on approaches to effective leadership, few have studied how social identity—both the leader’s and the group’s—impacts a leader’s effectiveness. We use a theoretical framework and a novel...

Creation of empirical knowledge in economics has taken a dramatic turn in the past few decades. One feature of the new research landscape is the nature and extent to which scholars generate data. Today, in nearly every field the experimental approach plays an increasingly crucial role in testing...

Under optimal tournament design, we would expect agents to exert identical effort regardless of the shape of the contest function’s error component. We report data from laboratory experiments that provide a first test of this prediction. We find that efforts do not significantly differ when...

We study default and endogenous leverage in the laboratory. To this purpose, we develop a general equilibrium model of collateralized borrowing amenable to laboratory implementation and gather experimental data. In the model, leverage is endogenous: agents choose how much to borrow using a risky...
