Economics, Psychology, and Social Dynamics of Consumer Bidding in Auctions ∗
Bibliographic record
Abstract
With increasing numbers of consumers in auction marketplaces, we highlight some recent approaches that bring additional economic, social, and psychological factors to bear on existing economic theory to better understand ∗ This paper is based on the special session at the 6th Triennial Invitational Choice Symposium, University of Colorado Boulder, June 2004 (co-chaired by the first two authors). † Corresponding author. 402 CHEEMA ET AL. and explain consumers ’ behavior in auctions. We also highlight specific research streams that could contribute towards enriching existing economic models of bidding behavior in emerging market mechanisms. Keywords: auctions, bidding, economic psychology, social dynamics, experimental economics The past decade has seen the advent and growth of online auction marketplaces, with online auction revenues expected to reach $36 billion by the year 2007 (C2C and B2C, (Laudon and Traver, 2004, p. 784). Study of specific auction formats for the past several decades has produced rich normative economic theories of rational buyers ’ and sellers ’ behavior (see Klemperer, 1999 for a review). A majority of these theories are developed for rational

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
