This paper studies heterogeneity in the reaction to rank feedback. In a laboratory experiment, individuals take part in a series of dynamic real-effort contests with intermediate feedback. To solve the identification problem in estimating the causal effect of rank feedback on subsequent effort...

We develop a public goods game (PGG) to measure cooperation and conditional cooperation in young children. Our design addresses several obstacles in adapting simultaneous and sequential PGGs to children who are not yet able to read or write, do not possess advanced abilities to calculate...

This paper empirically analyzes how performance feedback and information on heterogeneity affect behavior in dynamic contests, using data on two-player-contests from a smartphone/tablet application called ``Wordblitz for Friends''. We find that players increase output as underdogs and decrease...
