The automated negotiation process seems to be a powerful mechanism to resolve disputes arising from Internet-based transactions. Automated negotiation is an online blind-bidding process in which an automated algorithm evaluates bids from the parties and settles the case if the offers are within...

We study an assignment market where multiple heterogenous objects are sold to unit demand agents who have general preferences accommodating imperfect transferability of utility and income effects. In such a model, there is a minimum price equilibrium. We establish the structural...

We prove the existence of monotonic pure strategy equilibrium for many types of asymmetric auctions with n bidders and unitary demands, interdependent values and independent types. The assumptions require monotonicity only in the own bidder's type. The payments can be a function of all bids....

We describe a simple 2-stage mechanism whereby for two bargainers, a Buyer and a Seller, it is a weakly dominant strategy to report their reservation prices in the 1st stage. If the Buyer reports a higher price than the Seller, then the referee announces that there is the possibility for trade,...

This paper uses data from a natural experiment to compare two institutions: a simple English auction and bilateral bargaining. It appears that bilateral bargaining may be more profitable for the seller. Results also suggest no correlation between bargaining skills and an ability to make profit...

We test recent theory on the benefits of auctions and bargaining as alternative procurement mechanisms using data on the procurement of medical devices by Italian hospitals. Theory suggests that auctions perform well when cost control is the key concern, but are less effective at producing the...

Buyer-seller networks where price is determined by an ascending-bid auction are important in many economic examples such as certain real estate markets, radio spectrum sharing, and buyer-supplier networks. However, it may be that some sellers are better off not participating in the auction. We...

We examine the method by which firms are sold, auctions or one-on-one negotiations. We define and describe a subset of transactions that result from auction failure (i.e., target-attempted auctions that secure only one bidder). Controlling for endogeneity, firm, and transaction specific...

I study an auction model in which the auction is followed by bargaining between bidders. Bidders with multi-unit demand bid for an object and then bargain over additional units. In the presence of post-auction interaction between players, equilibrium bidding strategies are sensitive to the...

We analyze monetary exchange in a model that allows for directed search and multilateral matches. We consider environments with divisible goods and indivisible money, and compare the results with those in models that use random matching and bilateral bargaining. Two different pricing mechanisms...
