In this paper we design and test a competitive forecasting mechanism based on the Colonel Blotto game. In the game, forecasters allocate a fixed number of resources to different ‘battlefields’. Each field is realized with a probability that is determined by a stochastic process. Subjects learn about the underlying process during the course of the experiment(More)
Prediction markets serve as popular devices to aggregate beliefs and to assess market estimated probabilities.

We test our mechanism by eliciting beliefs about the termination times of a stochastic process in an experimental setting. We conduct two treatments, one with high and one with low(More)
