Proceedings of the fifteenth ACM conference on Economics and computation

The papers in these Proceedings were presented at the Fifteenth ACM Conference on Economics and Computation (EC'14), held June 8-12 in Palo Alto, CA, USA. With the goal of facilitating interaction between computer scientists and economists, the conference was collocated with a meeting of the NBER Market Design working group and with the NSF/CEME Decentralization Conference. Since 1999 the ACM Special Interest Group on Electronic Commerce (SIGecom) has sponsored EC, the leading scientific conference on advances in theory, systems, and applications at the interface of economics and computation, including applications to electronic commerce. The papers were selected by the program committee from among 290 submissions that were received by February 11, 2014. Paper submissions were invited in the following three nonexclusive focus areas: TF: Theory and Foundations AI: Artificial Intelligence and Applied Game Theory EA: Experimental, Empirical, and Applications In addition to the main technical program, EC'14 featured three workshops and four tutorials, joint sessions with the co-located NBER and Decentralization conferences, a poster session, a talk by ACM SIGecom Doctoral Dissertation Award winner Balasubramanian Sivan, and the following two keynote talks: Matthew Jackson: Centrality, Gossip, and Diffusion of Information in Networks Kevin Leyton-Brown: Pragmatic Algorithmic Game Theory The call for papers attracted 290 distinct submissions that were deemed to satisfy the formatting requirements. Each paper was reviewed by at least three program committee members and two senior program committee members on the basis of scientific novelty, technical quality, and importance to the field. Following the tradition of recent iterations of the conference, the authors were asked to align their submission with one or two of the tracks. Papers were reviewed by SPC members and PC members aligned with the track of the submission to provide a fair review process across different communities. Of the total of 290 submissions, 212, 73, and 63 chose the labels TF, AI, and EA, respectively, with 58 papers choosing dual tracks. After author feedback, and extensive discussion and deliberation among the program committee, senior program committee, and program chairs, 80 papers were selected for presentation at the conference. Of the 80 selected papers, 60, 19, and 17 have labels TF, AI, and EA, respectively. 56 of the accepted papers are published in these Proceedings. For the remaining 24, at the authors' request, only abstracts are included along with pointers to full working papers that the authors guarantee to be reliable for at least two years. This option accommodates the practices of fields outside of computer science in which conference publishing can npreclude journal publishing. We expect that many of the papers in these Proceedings will appear in a more polished and complete form in scientific journals in the future. Papers were presented in a mix of plenary and parallel sessions. To emphasize commonalities among the problems studied at EC, and to facilitate interchange at the conference, sessions were organized by topic rather than by focus area, and no indication of a paper's focus area(s) was given at the conference or appears in these Proceedings. Papers with high quality and broad appeal were selected for the single session talks. Some of the conference's technically strongest work addressed smaller cross-sections of the community, and so appeared in parallel sessions. We hope that you find this program interesting and thought-provoking and that the conference provides you with a valuable opportunity to share ideas with other researchers from institutions around the world.
