Abstract

Open or Sealed Bids in Buyer-Determined Auctions? Evidence from Online Labor Markets
 
Online labor markets recently emerged as a novel avenue for companies to identify and hire IT labor. These markets provide platforms facilitating Buyer-Determined (BD) auctions. In this paper, we study the effect of two BD auction designs-open bids and sealed bids-on bidder behavior and market performance. We first theoretically analyze equilibrium bidder entry and surplus, and derive our hypotheses on the comparison of the two auction designs in terms of entry barrier and market performance. Using a proprietary dataset based on 1,816,886 bids from 106,147 open bids and 9,950 sealed bids auctions posted on Freelancer.com by 41,530 unique buyers, we found open bids to consistently outperform sealed bids BD auctions in terms of buyer surplus, contract rate, and buyer satisfaction. We attribute performance differences to the "screening effect" that filters out low quality bidders in open bids auctions. We discuss implications for auction design and online labor markets.
