    Designing Risk-Averse Bidding Strategies in Sequential Auctions for Transportation Orders

    No full text
    Designing efficient bidding strategies for agents participating in multiple, sequential auctions remains an important challenge for researchers in agent-mediated electronic markets. The problem is particularly hard if the bidding agents have complementary (i.e. super-additive) utilities for the items being auctioned, such as is often the case in distributed transportation logistics. This paper studies the effect that a bidding agent’s attitude towards taking risks plays in her optimal, decision-theoretic bidding strategy. We model the sequential bidding decision process as an MDP and we analyze, for a category of expectations of future price distributions, the effect that a bidder’s risk aversion profile has on her decision-theoretic optimal bidding policy. Next, we simulate the above strategies, and we study the effect that an agent’s risk aversion has on the chances of winning the desired items, as well as on the market efficiency and expected seller revenue. The paper extends the results presented in our previous work (reported in [1]), not only by providing additional details regarding the analytical part, but also by considering a more complex and realistic market setting for the simulations. This simulation setting is based on a real transportation logistics scenario [2]), in which bidders have to choose between several combinations (bundles) of orders that can be contracted for transportation

    David Zimmer Christmas letter

    No full text
    This Christmas letter written November 30, 1999, by David Zimmer is titled "Season's Greetings from the last of the Red-Hot-Santas!" It features an illustration of Santa Claus with a guitar, and a summary of Zimmer's year. David Zimmer (1929-2005) was born in Harrisburg, Ohio. He enlisted in the U.S. Army and served for two years during the Korean War at the Brooke Army Medical Center in San Antonio, where he performed in drag for wounded soldiers. After the war, he returned to Ohio. Zimmer performed as Dolly Divine, a name inspired by the song "Hello Dolly." In 1964, he established the Berwick Ball with Orn Huntington, another important early gay activist in Central Ohio. The Ball began as a formal Halloween costume ball that provided a safe space to gather and enjoy drag shows for the gay community each year; over the years, it grew into an annual Halloween tradition and an important fundraiser for the AIDS movement and other charities. During the 1970s, Zimmer was also known for hosting lavish parties at his Harrisburg home. In 1989, he moved to the German Village area of Columbus where he remained active in the community. During the 1990s, Zimmer continued to perform in and out of drag and commissioned costume designer Dick Frank to make elaborate outfits. Zimmer worked for Huntington National Bank for 39 years and was a member of the Harrisburg United Methodist Church, Veterans of Foreign Wars and the German Village Society
