Manipulative authorities can bunch tenders just below thresholds to implement noncompetitive procurement practices. I use regression discontinuity manipulation tests identify the bunching scheme. investigate European Union public data set that covers more than two million contracts. The results show 10–13% of examined exhibit a high probability bunching. These are less likely employ competitive...

We demonstrate how to make voting protocols resistant against manipulation by computationally bounded malicious voters, by extending the previous results of Conitzer and Sandholm in several important directions: we use one-way functions to close a security loophole that allowed voting officials to exert disproportionate influence on the outcome and show that our hardness results hold against a ...

One of the current areas of research in robotics is in the development of robots which can interact with humans in performing a variety of tasks. In particular, there is a desire to enable robots to use objects as tools to perform tasks. For example, assembly tasks may require the robot to use a screwdriver to tighten screws or a hammer for nailing. In this project, I am concerned with the prob...
