Biasing Unbiased Dynamic Contests

We consider a best-of-three Tullock contest between two ex-ante identical players. An effort-maximizing designer commits to a vector of player-specific biases (advantages or disadvantages). When the designer can choose victory-dependent biases (i.e., the biases depend on the record of matches won by players), the effort-maximizing biases eliminate the discouragement effect, leaving players equally likely to win each match and the overall contest. This is in contrast with the common „favor-the-leader“ result in the literature. Instead, when the designer can only choose victory-independent biases, the effort-maximizing biases leave players unequally likely to win each match and the overall contest. The appeal of this result comes from the players being ex-ante identical; thus, it challenges the conventional wisdom of the optimality of unbiased contests. This result also has an applied interest, as it shows that alternating biases, as when teams alternate home and away matches, may increase total effort as opposed to an unbiased contest. This result holds in Tullock contests and all-pay auctions, as well as under maximization of total effort and winner‘s effort.

Optimisation in Space: Problems in Spacecraft Trajectory Optimisation

In recent years, spacecraft navigation and control has achieved astonishing feats. As a recent example, the journey of ESA's Rosetta craft through the inner Solar System lasted ten years and covered 6.4 billion km until the lander Philae landed on comet 67P in November 2014. Likewise, the Japanese craft Hayabusa2 will fly 5.4 billion kilometers within six years in order to return samples from the asteroid Ryugu to Earth. In this talk, we highlight some of the difficulties of planning corresponding flight paths of future missions in an optimal fashion, present some of the underlying mathematical models, and discuss methods from mathematical optimization that help to attain such amazing accomplishments.
