Revealed preference techniques are used to test whether a data set is compatible with rational behaviour. They are also incorporated as constraints in mechanism design to encourage truthful behaviour in applications such as combinatorial auctions. In the auction setting, we present an efficient combinatorial algorithm to find a virtual valuation function with the optimal (additive) rationality guarantee. Moreover, we show that there exists such a valuation function that both is individually…

### Welfare and Rationality Guarantees for the Simultaneous Multiple-Round Ascending Auction

It is shown that by bidding securely, it is possible to obtain the same welfare guarantees as truthful bidding without the loss of individual rationality in the SMRA with general valuation functions.

### Ju l 2 01 8 Revealed Preference Dimension via Matrix Sign Rank

- Computer Science
- 2018

This paper solves the open problem of determining exactly which graphs are attainable as revealed preference graphs in d-dimensional markets via an exact characterization which closely ties the feasibility of the graph to the Matrix Sign Rank of its signed adjacency matrix.

This paper shows that CCA does provide strong guarantees on social welfare provided the price increment and stopping rule are well-chosen, and shows that the welfare ratio of the CCA is at least Ω([EQUATION]).

Spectrum auctions are used by governments to assign and price licenses for wireless communications. The standard approach is the simultaneous ascending auction, in which many related lots are…

### Conditional equilibrium outcomes via ascending price processes with applications to combinatorial auctions with item bidding

- EconomicsEC '12
- 2012

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.

Further evolutionary changes are described, including new activity rules, new approaches to pricing, and an integration of non-mutually-exclusive bids, which will help to address performance issues of the Combinatorial Clock Auction.

### A revealed preference approach to computational complexity in economics

- EconomicsEC '11

This work proves the possibly surprising result that computational constraints have no empirical consequences for consumer choice theory, and motivates a general approach for posing questions about the empirical content of computational constraints: the revealed preference approach to computational complexity.
