Traditional auction theory assumes that bidders possess values defined solely on the auctioned object. There may, however, be cases in which bidders possess preferences over the revenue achieved by the auctioneer. We present here a comprehensive framework of price preference valuations, unifying several phenomenon ranging from preference for charitable giving to shill bidding. We compare expect...

Online media offers opportunities to marketers to deliver brand messages to a large audience. Advertising technology platforms enables the advertisers to find the proper group of audiences and deliver ad impressions to them in real time. The recent growth of the real time bidding has posed a significant challenge on monitoring such a complicated system. With so many components we need a reliabl...

Recent work in experimental economics has raised that observed behavior depends on whether wealth was windfall or earned. This paper extends this work by considering whether earned wealth a ects bidding behavior in an induced-value second-price auction. We nd people bid more sincerely in the auction with earned wealth given monetary incentives; earned wealth did not induce sincere bidding in hy...

When bidders are not substitutes, we show that there is no standard ascending auction that implements a bidder-optimal competitive equilibrium under truthful bidding. Such an impossibility holds also in environments where the Vickrey payoff vector is a competitive equilibrium payoff and is thus stronger than de Vries, Schummer and Vohra’s [On ascending Vickrey auctions for heterogeneous objects...

We present a new hardware architecture to compute scalar multiplications in the group of rational points of elliptic curves defined over a prime field. We have made an implementation on Altera FPGA family for some elliptic curves defined over randomly chosen ground fields offering classic cryptographic security level. Our implementations show that our architecture is the fastest among the publi...

Spoofing (canonically: ‘bidding or offering with the intent to cancel bid offer before execution’), once a valued skill in face-to-face trading, has become crime punishable by jail. Echoing Riles’s call for greater attention law research on finance, this paper analyses interwoven processes of dramatic shift, including trading’s changing material form, contingencies such as Congressional respons...

Throughout this work we deal with a natural number g ≥ 2 and with an algebraically closed field k whose characteristic differs from 2. A hyperelliptic curve of genus g over k is a smooth curve of genus g, that is a double cover of the projective line P. The Riemann-Hurwitz formula implies that this covering should be ramified at 2g + 2 points. Because of this explicit description, hyperelliptic...

Contract bridge is an example of an incomplete information game for which computers typically do not perform better than expert human bridge players. In particular, the typical bidding decisions of human bridge players are difficult to mimic with a computer program, and thus automatic bridge bidding remains to be a challenging research problem. Currently, the possibility of automatic bidding wi...
