In this paper we analyse scoring auctions with general non-quasilinear scoring rules. We assume that cost function of each firm is additively separable in quality and type. In sharp contrast to the recent results in the literature we show the following. (i) Equilibria in scoring auctions can be...

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 paper analyses the incentives to adopt cost-reducing technology by firms in a horizontally differentiated industry. In our model there are several suppliers of a new technology. The extent of the cost reduction depends on the quality of the new technology. A firm has to buy the technology...

Consider the problem of allocating objects to agents and how much they should pay. Each agent has a preference relation over pairs of a set of objects and a payment. Preferences are not necessarily quasi-linear. Non-quasi-linear preferences describe environments where payments influence agents'...

Auctions are a popular and prevalent form of trading mechanism, despite the restriction that the seller cannot price-discriminate among potential buyers. To understand why this is the case, we consider an auction-like environment in which a seller with an indivisible object negotiates with two...

This paper analyzes an auction mechanism that excludes overoptimistic bidders inspired by the rules of the procurement auctions adopted by several Japanese local governments. Our theoretical and experimental results suggest that the endogenous exclusion rule reduces the probability of suffering...

Several Japanese local governments started to add endogenous minimum prices to firstprice auctions in their public procurements. Any bid less than the endogenous minimum price is referred to as abnormally low and is excluded from the procurement procedure. The endogenous minimum price is...

This paper analyzes an all-pay auction where the winner is determined according to the sum of the bid and a handicap endowed to all players. The bidding strategy in equilibrium is then explicitly derived as a 'piecewise affine transformation' of the equilibrium strategy in an all-pay auction...
