We examine auction data to determine if bid rigging presents in procurement auctions for paving works in Ibaraki City, Osaka, Japan. We first show that sporadic bidding wars are caused by the participation of potential 'outsiders.' Assuming that the ring is all-inclusive if the auction is not...

This study constructs a model of anticompetitive exclusive contracts in the presence of complementary inputs. A downstream firm transforms multiple complementary inputs into final products. When complementary input suppliers have market power, upstream competition within a given input market...

The demand for goods like seasonal fashion apparel is uncertain but the lead time needed for production is long, and so it is necessary to set the production quantity before the demand is fully known. Once sale begins, if demand is less than anticipated, the price will be low. In a futile...

This study constructs a model for examining anticompetitive exclusive supply contracts that prevent an upstream supplier from selling input to a new downstream firm. With regard to the technology to transform the input produced by the supplier, as an entrant becomes increasingly efficient, its...

This study constructs a simplest model to examine anticompetitive exclusive contracts that prevent a downstream buyer from buying input from a new up-stream supplier. Incorporating Nash bargaining into the standard one-buyer-one-supplier framework in the Chicago School critique, we show a...

This study constructs a model of anticompetitive exclusive-offer competition between two existing upstream firms. Under exclusive-offer competition, the upstream firm's profit depends on the rival's exclusive offer. If the rival makes an exclusive offer acceptable for the downstream firm, the...

We explore the supply chain problem of a downstream durable goods monopolist, who chooses one of the following trading modes: an exclusive supply chain with an incumbent supplier or an open supply chain, allowing the monopolist to trade with a new efficient entrant in the future. The predicted...

We consider exclusive contracts as a survival strategy for a local incumbent manufacturer facing a multinational manufacturer's entry. Although both manufacturers prefer to trade with an efficient local distributor, trading with inefficient competitive distributors is acceptable only to the...

We construct a two-period model of the supply chain's openness in a durable goods market by introducing two marketing modes: leasing and selling. Given a marketing mode, at the beginning of the first period, an incumbent supplier and the downstream monopolist choose one of the trading modes: (i)...
