Systems theory and agency theory were employed as the theoretical bases for a study of lobbying and the International Accounting Standards Committee (IASC) during the years of the Core Standards Programme, 1993-98. External parties made use of formal and informal channels to lobby the IASC. The...

We report on the use of a quadratic programming technique in recent and upcoming spectrum auctions in Europe. Specifically, we compute a unique point in the core that minimizes the sum of squared deviations from a reference point, for example, from the Vickrey-Clarke-Groves payments. Analyzing...

Motivated by markets for television advertising time-slots, we introduce a new combinatorial auction format, including a general method for approximating core-selecting payments for hard problems. Given the size and complexity of ad markets in practice, an enumerative XOR bidding language...

In a combinatorial exchange, agents can express their desire to buy, sell, or trade combinations or packages of items. Though the combinatorial exchange paradigm provides one of the most general frameworks for a centralized market mechanism, the concept is difficult to apply in practice, because...

Much of the prominent literature describing behavior in eBay-like marketplaces emphasizes the successful use of “sniping” agents that wait until the last moments of an auction to bid (truthfully) on behalf of a human user. These agents fare well against “naïve” agents (typically assumed...

Over the last decade there has been significant interest and attention devoted towards understanding the complex structure of the Internet, particularly its topology and the large-scale properties that can be derived from it. While recent work by empiricists and theoreticians has emphasized...
