On characterizations of truthful mechanisms for combinatorial auctions and scheduling
We characterize truthful mechanisms in two multi-parameter domains. The first characterization shows that every mechanism for combinatorial auctions with two subadditive bidders t...

Frugality in path auctions
We consider the problem of picking (buying) an inexpensive s-t path in a graph where edges are owned by independent (selfish) agents, and the cost of an edge is known to its owner...

Collusion-Resistant Mechanisms with Verification Yielding Optimal Solutions
A truthful mechanism consists of an algorithm augmented with a suitable payment function which guarantees that the "players" cannot improve their utilities by "chea...

Auctions with online supply
We study the problem of selling identical goods to n unit-demand bidders in a setting in which the total supply of goods is unknown to the mechanism. Items arrive dynamically, and...

Towards a Characterization of Truthful Combinatorial Auctions
This paper analyzes implementable social choice functions (in dominant strategies) over restricted domains of preferences, the leading example being combinatorial auctions. Our wo...

Computationally-Feasible Truthful Auctions for Convex Bundles
In many economic settings, convex figures on the plane are for sale. For example, one might want to sell advertising space on a newspaper page. Selfish agents must be motivated ...

On the Price of Truthfulness in Path Auctions
We study the frugality ratio of truthful mechanisms in path auctions, which measures the extent to which truthful mechanisms “overpay” compared to non-truthful mechanisms. In p...

Using Nash Implementation to Achieve Better Frugality Ratios
Most of the recent works on algorithmic mechanism design exploit the solution concept of dominant strategy equilibria. Such work designs a proper payment scheme so that selfish ag...

The Geometry of Truthfulness
We study the geometrical shape of the partitions of the input space created by the allocation rule of a truthful mechanism for multi-unit auctions with multidimensional types and ...

Truthful Mechanisms via Greedy Iterative Packing
An important research thread in algorithmic game theory studies the design of efficient truthful mechanisms that approximate the optimal social welfare. A fundamental question is ...
