近年来，计算机科学和经济学之间的思想和研究目标出现了融合。计算机科学促进了新型计算平台的发展，这些平台需要经济和工程思维来进行适当的设计和研究；主要的例子是那些由Internet创建和启用的系统。经济学引入了定量模型和工具来分析这些系统。同时，很明显，这些模型和工具的计算性质对于它们用于研究具有数千甚至数百万相互作用的个体的系统至关重要。在这种认识的推动下，计算机科学家在过去十年中对博弈论和经济学进行了全新的计算研究。其中一个主要焦点是算法机制设计（Algorithmic Mechanism Design），我们在其中寻求计算效率高的系统，这些系统设计得非常巧妙，以至于用户的自私行为有助于推进设计师的目标。该提案的目标是从两个方向丰富算法机制设计，而在PI看来，这两个方向在文献中还没有得到充分的探讨。我们的目标是(i)了解拍卖的复杂性如何影响其性能，以及（ii）将算法机制设计应用于拍卖以外的系统。

Recent years have seen a convergence of ideas and research goals between Computer Science and Economics. Computer Science enabled the development of a new genre of computational platforms that require economic as well as engineering thinking for their proper design and study; primary examples are those systems created and enabled by the Internet. Economics brought to the discussion quantitative models and tools useful to analyze these systems. At the same time, it became clear that the computational nature of these models and tools is crucial for them to be used to study systems with thousands or even millions of interacting individuals. Motivated by this realization, computer scientists have taken in the past decade a fresh, computational look at Game Theory and Economics. One major focus is Algorithmic Mechanism Design, in which we seek for computational efficient systems that are so cleverly designed that users’ selfish behavior helps advance the designer's objectives. The goal of this proposal is to enrich Algorithmic Mechanism Design from two directions that – to the PI’s opinion – has not been sufficiently explored in the literature. We aim (i) to understand how the complexity of an auction affects its performance, and (ii) to apply Algorithmic Mechanism Design to systems beyond auctions.
