abstract
In a two-tier industry with bottleneck upstream and two downstream firms producing verticallydifferentiated goods, we identify conditions under which the upstream supplier chooses exclusive ornon-exclusive negotiations, or an English auction to sell its essential input. Auctioning off a two-parttariff contract is optimal for the supplier when its bargaining power is low and the final goods are nottoo differentiated. Otherwise, the supplier enters into exclusive or non-exclusive negotiations with the downstream firm(s). Finally, in contrast to previous findings, an auction is never welfare superior tonegotiations.
