In a laboratory setting, we explore strategic discrimination in principal-agent relationships, which arises from mutually reinforcing expectations of identity-contingent choices. Our experimental design isolates the influence environment effects other sources discrimination, including statistical differences between subpopulations and outright prejudice. We find that, principals who reward agen...

In this paper, we present an overview over existing speed-up techniques for timedependent route planning. Apart from only explaining each technique one by one, we follow a more systematic approach. We identify basic ingredients of these recent techniques and show how they need to be augmented to guarantee correctness in time-dependent networks. With the ingredients adapted, three efficient spee...
