This paper develops characterizations of identified sets of structures and structural features for complete and incomplete models involving continuous or discrete variables. Multiple values of unobserved variables can be associated with particular combinations of observed variables. This can...

This paper analyzes a unique dataset of art auctions on eBay. We studythe behavior of buyers and sellers, demand and supply, by means of anovel structural estimation approach. Our empirical framework considersthe process of arrival of new bidders as well as the distribution ofbidder valuations...

An incomplete model of English auctions with symmetric independent private values, similar to the one studied in Haile and Tamer (2003), is shown to fall in the class of Generalized Instrumental Variable Models introduced in Chesher and Rosen (2014). A characterization of the sharp identi.ed set...

In this paper we analyse a common value English auction. We argue that rational bidders attempt to estimate each other’s private signals, to take advantage of the additional information disclosed through the bids. If this happens, herd behaviour might arise, because a particular bidder may...

This paper tests experimentally, in a common value setting, the equivalence between the Japanese English auction (or clock auction) and an open outcry auction, where bidders are allowed to call their own bids. We find that (i) bidding behaviour is different in each type of auction, but also that...

This paper analyses a model of a common value English auction with discrete bidding. In this model, we show that there exists a communication equilibrium in which the high signal bidder strategically chooses his first bid so as to maximise his expected utility. Straightforward bidding, or...

Evidence on adverse selection in slave markets remains inconclusive. We study this question through notarial acts on public slave auctions in Mauritius between 1825 and 1835, involving 4,286 slaves. In addition to slave characteristics, the acts document the identities of buyers and sellers. We...

I introduce a property of player's valuations that ensures the existence of an ex post efficient equilibrium in asymmetric English auctions. The use of this property has the advantage of yielding an ex post efficient equilibrium without assuming differentiability of valuations or that signals...
