This study examines the effects of donation incentives on labor supply in an online labor market through a field experiment (_n_ = 944). We manipulate the donation purpose of the incentive to be either unifying or polarizing and the size of the donation relative to the workers’ wage. Our experimental design allows us to observe the decision to accept a job (extensive margin) and different dimensions of productivity (intensive margin). We predict and show that a unifying donation purpose attracts more (...) gig workers and improves their productivity compared to a polarizing donation purpose. We discuss the implications of these results in order to understand the role of donation incentives and labor supply in online labor markets. (shrink)

Available for the first time in a single volume, Ranier Maria Rilke’s two most beloved sequences of poems rendered by his most faithful translator. Rilke is unquestionably the twentieth century’s most significant and compelling poet of romantic transformation and spiritual quest. His poems of ecstatic identification with the world exert perennial fascination. In Stephen Mitchell’s versions of Rilke’s two greatest masterpieces readers will discover an English rendering that captures the lyric intensity, fluency, and reach of his poetry. Stephen Mitchell adheres (...) impeccably to Rilke’s text, to his formal music, and to the complexity of his thought; at the same time, Mitchell’s work has authority and power as poetry in its own right.
