We characterize revenue maximizing head starts for all-pay auctions and lottery contests with many heterogeneous players. We show that under optimal head starts all-pay auctions revenue-dominate lottery contests for any degree of heterogeneity among players. Moreover, all-pay auctions with optimal head starts induce higher revenue than any multiplicatively biased all-pay auction or lottery cont...

In a tedious real effort task, subjects know that their piece rate is either low or ten times higher. When subjects are informed about their piece rate realization, they adapt their performance. One third of subjects nevertheless forego this instrumental information when given the choice — and perform stunningly well. Agents who are uninformed regarding their piece rate tend to outperform all o...

IMPORTANCE Operating room (OR) turnaround times (TATs) and on-time first-case starts (FCSs) are commonly used measures of OR efficiency. Prolonged TATs and late FCSs occur frequently at academic medical centers. OBJECTIVE To test the hypothesis that establishing a financial incentive program (FIP) for OR teams would improve efficiency, leading to decreased TATs and improved on-time FCSs. DE...
