Simultaneous item auctions are simple and practical procedures for allocating items to bidders with potentially complex preferences. In a simultaneous auction, every bidder submits independent bids on all items simultaneously. The allocation and prices are then resolved for each item separately, based solely on the bids submitted on that item. We study the efficiency of Bayes-Nash equilibrium (BNE) outcomes of simultaneous first- and second-price auctions when bidders have complement-free (a.k… Expand
Bayesian Combinatorial Auctions
TLDR
It is shown that if bidders have submodular or, more generally, fractionally subadditive valuation functions, every Bayes-Nash equilibrium of the resulting game provides a 2-approximation to the optimal social welfare. Expand
Simple Auctions with Simple Strategies
TLDR
Welfare guarantees hold for Nash equilibria and no-regret learning outcomes in both Bayesian and complete information settings via the smooth-mechanism framework and efficiency guarantees of a mechanism via smoothness for a very restricted class of cardinality valuations extend to subadditive valuations, the largest complement-free class of valuations. Expand
On the Inefficiency of the Uniform Price Auction
TLDR
This work studies equilibria of the Uniform Price Auction for bidders with (symmetric) submodular valuation functions, over the number of units that they win and proves a bound of 4-2/k on the economic inefficiency of (mixed) Bayes Nashequilibria that are supported by undominated strategies. Expand
On the Complexity of Computing an Equilibrium in Combinatorial Auctions
TLDR
It is shown that when the valuations of the bidders are submodular, computing an equilibrium with goodelfare is essentially as easy as computing, completely ignoring incentives issues, an allocation with good welfare, and that for subadditive valuations, Computing an equilibrium requires exponential communication. Expand
Simple combinatorial auctions with budget constraints
TLDR
An upper bound of 2 is shown on the price of anarchy for any auction in this class of simple combinatorial auctions, as well as a tight corresponding lower bound on the prices of stability for all auctions whose payment rules are convex combinations of the bids. Expand
Uniform Price Auctions: Equilibria and Efficiency
TLDR
This work provides the first (constructive) proof of existence of pure Nash equilibria in undominated strategies and the first performance evaluation (with respect to economic efficiency) of this popular auction format. Expand
Risk-Free Bidding in Complement-Free Combinatorial Auctions
TLDR
The main results are for the class of fractionally subadditive (XOS) bidders, where it is shown that for both first-price and second-price sequential auctions Bidder 1 has a strategy that guarantees a profit of at least \((\sqrt{B_1}-\sqrt {B_2})^2\) when \(B-2 \le B_1\), and this bound is tight. Expand
Inefficiency of Standard Multi-unit Auctions
TLDR
This work evaluates the economic inefficiency of both multi-unit auction formats for both bidding interfaces, by means of upper and lower bounds on the Price of Anarchy for pure Nash equilibria and mixed Bayes-NashEquilibria. Expand
Limits of Efficiency in Sequential Auctions
TLDR
The efficiency of sequential first-price item auctions at subgame perfect equilibrium is studied and it is shown that even in the very restricted case in which each bidder has either an additive valuation or a unit-demand valuation, there exist instances in which the inefficiency at equilibrium grows linearly with the minimum of the number of items and thenumber of bidders. Expand
Uniform Price Auctions: Equilibria and Efficiency
TLDR
This work characterize a class of undominated pure Nash equilibria of the Uniform Price Auction in undominated strategies and quantify the social inefficiency of pure and (mixed) Bayes-NashEquilibria by means of bounds on the Price of Anarchy. Expand

Simultaneous Single-Item Auctions
TLDR
A thorough understanding of the price of anarchy, as a function of the single-item auction payment rule, is provided and a strong optimality result for the canonical second-price auction is proved. Expand

Welfare guarantees for combinatorial auctions with item bidding
TLDR
It is proved that under a standard "no overbidding" assumption, for every subadditive valuation profile, every pure Nash equilibrium has welfare at least 50% of optimal --- i.e., the POA is at most 2. Expand
Pure and Bayes-Nash Price of Anarchy for Generalized Second Price Auction
TLDR
This paper is the first to prove bounds on the price of anarchy, and to give any bounds in the Bayesian setting, and exhibits a combinatorial structure of Nash equilibria and uses this structure to bound the priceof anarchy. Expand
On the efficiency of equilibria in generalized second price auctions
TLDR
The proof exploits the equilibrium conditions developed in [16] and follows by a detailed reasoning about the structure of equilibria and a novel relation of the price of anarchy to the objective value of a compact mathematical program. Expand
Auctions of Heterogeneous Objects
Abstract Simultaneous sealed bid auctions of heterogeneous objects are analyzed. Each bidder's reservation value for an object depends upon the other objects he obtains. Bidders' reservation valuesExpand

Conditional equilibrium outcomes via ascending price processes with applications to combinatorial auctions with item bidding
TLDR
This paper studies a relaxed notion, "conditional equilibrium", that requires individual rationality and "outward stability", and asks what is a maximal valuation class that ensures the existence of a conditional equilibrium and includes unit-demand valuations. Expand
GSP auctions with correlated types
TLDR
It is demonstrated that the Bayesian Price of Anarchy of the GSP auction is bounded by $4, even when agents have arbitrarily correlated types, which highlights a connection between the G SP mechanism and the concept of smoothness in games, which may be of independent interest. Expand
Non-price equilibria in markets of discrete goods
TLDR
An analysis of the welfare properties of mixed-Nash equilibria of the market viewed as a game shows that while pureEquilibrium are always perfectly efficient, mixedEquilibria need not be, and upper and lower bounds on their amount of inefficiency are provided. Expand
