The present paper proposes a theoretical model of the equilibrium bidding behavior in simultaneous competing private-value Internet auctions such as those on eBay. It shows that last-minute bidding and multiple bidding, two commonly observed bidding strategies, arise in equilibrium. It also...

Objectives: Online auctions have emerged as a major opportunity for individuals to start businesses or for established businesses to diversify and grow their markets. To-date, research interest has focused largely on the technological entrepreneur rather than the Internet based (cyber)...

Structural econometric auction models with explicit game-theoretic modeling of bidding strategies have been quite a challenge from a methodological perspective, especially within the common value framework. We develop a Bayesian analysis of the hierarchical Gaussian common value model with...

This dissertation develops a dynamic bidding model for Internet auctions, especially eBay. The model parameters, namely bidders’ valuations and bidding costs, are then structurally estimated using a data set of around 800 eBay auctions for a handheld computer. Identification of the parameters...

This paper proposes a framework for demand estimation with data on bids, bidders' identities, and auction covariates from a sequence of eBay auctions. First the aspect of bidding in a marketplace environment is developed. Form the simple dynamic auction model with IPV and private bidding costs...

Although bidders in an internet auction do not obtain the actual ownership of the item during the auction, they still act according to an endowment effect. In a unique data set of 17,000 Danish furniture auctions I find that having the leading bid, both in terms of time and dollars, will...

A classic argument in economics is that experience in the market place will eliminate mistakes and cognitive biases. Internet auctions are a popular market were some bidders gather extensive experience. In a unique data set from a Scandinavian auction site I question if and what bidders learn....

Most internet auction sites, like eBay, use a proxy bidding system where bidders can put in their maximum bid and let a proxy bidder (a computer) bid for them. Yet many bidders speculate about how to bid and employ bidding strategies. This paper examines how the timing of bids can affect the...
