Auctions with entry and resale

► We study how resale affects auctions with costly entry where bidders possess two-dimensional private types: entry costs and valuations. ► We establish the existence of symmetric entry equilibrium and identify sufficient conditions under which the equilibrium is unique. ► The opportunity of resale affects both entry and bidding; it induces motivation for speculative entry and resale hunting abstentions. ► The effects of resale on expected revenue and efficiency are both ambiguous.
