We offer experimental and theoretical evidence that large, sealed-bid, multi-unit common value auctions for assets with substantial price uncertainty may be improved through hybrids with a separate retail tranche or ‘public pool.' The auctions in our laboratory experiments incorporate initial...

We explore the role of capacity constraints in establishing efficient pricing in multi-unit common value auctions in a setting relevant to auction-based equity IPOs. The method of inquiry is experimental economics. We find that sufficiently large capacity constraints mitigate the overbidding...
