We construct prior-free auctions with constant-factor approximation guarantees with ordered bidders, in both unlimited and limited supply settings. We compare the expected revenue of our auctions on a bid vector to the monotone price benchmark, the maximum revenue that can be obtained from a bid vector using supply-respecting prices that are nonincreasing in the bidder ordering and bounded above by the second-highest bid. As a consequence, our auctions are simultaneously near-optimal in a wide…

The characterization identifies the worst-case distribution of instances and reveals intrinsic relations between competitive ratios and benchmarks in the competitive analysis, which establishes a sufficient and necessary condition that characterizes competitive ratios for all monotone benchmarks.

The sample complexity of auctions with side information

- EconomicsSTOC
- 2016

This work introduces an alternate model, where bidders are a priori identical, but can be distinguished based (only) on some side information the auctioneer obtains at the time of the auction.

Core-competitive Auctions

- EconomicsEC
- 2015

This paper designs an incentive-compatible auction whose revenue is comparable (even if less) to a competitive outcome and defines a notion of core-competitive auctions, which are known for having good revenue properties and lack the desired incentive-compatibility property of the VCG auction.

Simple vs Optimal Auctions: An Experimental Investigation

In single object auctions when bidders are asymmetric, the Myersonian optimal auction is di¢ cult to implement because of its complexity and possible discouragement e¤ect on the bidders. In these…

Prior-free auctions with ordered bidders

- EconomicsSTOC '12
- 2012

A simple prior-free auction for digital goods with ordered bidders, the Random Price Restriction (RPR) auction is designed and it is proved that its expected revenue on every bid profile b is Ω(M(b)/log*n), where M denotes the monotone-price benchmark and log*n denotes the number of times that the log2 operator can be applied to n before the result drops below a fixed constant.

Competitive auctions and digital goods

- EconomicsSODA '01

It is shown that for any truthful auction, even a multi-price auction, the expected revenue does not exceed that for optimal fixed pricing, and a bound on how far the revenue can be from the total market utility is given.

Limited and online supply and the bayesian foundations of prior-free mechanism design

- EconomicsEC '09
- 2009

The Bayesian optimal mechanism for these variants of auctions for selling a limited supply of a single commodity is described and the random sampling auction is extended to address the prior-free case.

Simple versus optimal mechanisms

The monopolist's theory of optimal single-item auctions for agents with independent private values can be summarized by two statements. The first is from Myerson [8]: the optimal auction is Vickrey…

Prior-Independent Multi-parameter Mechanism Design

- MathematicsWINE
- 2011

This paper presents a prior-independent auction that is guaranteed to achieve a constant fraction of the optimal expected profit for a large class of, so called, "regular" distributions, without specific knowledge of the distributions.

Revenue maximization with a single sample

- Economics, MathematicsEC '10
- 2010

This work designs and analyzes approximately revenue-maximizing auctions in general single-parameter settings and gives an auction that, for every environment and unknown valuation distributions, has expected revenue at least a constant fraction of the expected optimal welfare.

Envy, truth, and profit

- EconomicsEC '11
- 2011

It is shown that envy-free pricing has a simple nice structure and a strong connection to incentive compatible mechanism design, and this connection is exploited to design prior-free mechanisms with strong approximation guarantees.

Envy-free auctions for digital goods

- EconomicsEC '03
- 2003

The main result is to show that no constant-competitive auction that is truthful and always gives outcomes are envy-free, and two relaxations of these requirements are considered, allowing the auction to be untruthful with vanishingly small probability, and to give non-envy-free outcomes.

Supply-limiting mechanisms

- EconomicsEC '12
- 2012

It is proved that "supply-limiting mechanisms" achieve near-optimal expected revenue in a range of single- and multi-parameter Bayesian settings, and essentially match the state-of-the-art in prior-independent mechanism design.

Optimal and Efficient Parametric Auctions

- EconomicsSODA
- 2013

This work shows that, for very general feasibility constraints, only knowledge of the median of each party's value distribution, or any other quantile of these distributions, or approximations thereof, suffice for designing simple auctions that simultaneously approximate both the optimal revenue and the optimal welfare.
