We study multiple parallel contests where contest organizers elicit solutions to innovation-related problems from a set of solvers. Each solver may participate in multiple contests and exert effort to improve her solution for each contest she enters, but the quality of her solution at each...

In a contest in which solvers with heterogeneous expertise exert effort to develop solutions, a recent paper (Terwiesch, C., Y. Xu. 2008. Innovation contests, open innovation and multiagent problem solving. Management Science. 54(9) 1529--1543) argues that as more solvers enter the contest,...

We study parallel innovation contests where contest organizers elicit innovative solutions to a set of problems from a group of solvers with limited (financial, time, cognitive) resources. The quality of a solver's solution improves with their effort, yet it is also subject to an output...
