This paper empirically examines the relationship between trading intensity and price in the US existing home markets. In particular, I have tested two recent theories, the search model by Wheaton (1990) and the "downpayment" model by Stein (1995). The search model predicts that trading volume should positively affect real home price, while the "downpayment" model predicts that, with liquidity c...

Efficiently coordinating the often large number of interdependent, timetabled train movements on a railway junction, while satisfying a number of operational requirements, is one of the most important problems faced by a railway company. The most critical variant of the problem arises on a daily basis at major railway junctions where disruptions to rail traffic make the planned schedule/routing...

When combinatorial bidding is permitted in auctions, such as the proposed FCC auction #31, the resulting full valuations and winner-determination problem can be computationally challenging. We present a branch-and-price algorithm based on a set-packing formulation originally proposed by Dietrich and Forrest (2002). This formulation has a variable for every possible combination of winning bids f...
