This market covers about 800 routes serving an area of 1,630 square kilometers and more than 3.5 million passengers per day. It is valued at 600 million Pounds per year (roughly US $900 million). Prior to deregulation,(More)
In 2007 all ECB publications feature a motif taken from the €20 banknote. 1 We have accumulated a debt to many people during this project. We are very grateful to Eurex and LIFFE for giving us access to their archives, and especially to Stefan Engels (Eurex) and Stuart Sloan (LIFFE) for tracking the data and coordinating the collection at these exchanges.(More)
Bidders' asymmetries are widespread in auction markets. Yet, their impact on behavior and, ultimately, revenue and profits is still not well understood. This paper defines a natural benchmark auction environment to which to compare any private values auction with asymmetrically distributed valuations. The main result is that the expected revenue from the(More)

We use a simple graphical approach to represent Social Welfare Functions that satisfy Independence of Irrelevant Alternatives and Anonymity. This approach allows us to provide simple and illustrative proofs of May's Theorem, of variants of classic impossibility results, and of a recent result on the robustness of Majority Rule due to Maskin (1995). In each(More)
