Using Auction Theory to Inform Takeover Regulation

This paper focuses on certain mechanisms that govern the sale of corporate assets. Under Delaware law, when a potential acquirer makes a serious bid for a target, the target's Board of Directors is required to act as would "auctioneers charged with getting the best price for the stock- holders at a sale of the company." The Delaware courts' preference for auctions follows from two premises. First, a firm's managers should maximize the value of their shareholders' investment in the company. Second, auctions maximize shareholder returns. The two premises together imply that a target's board should conduct an auction when at least two firms would bid sums that are nontrivially above the target's prebid market price.Auctions; Takeovers

Understanding Overbidding in Second Price Auctions: An Experimental Study

This paper presents results from a series of second price private value auction (SPA) experiments in which bidders are either given for free, or are allowed to purchase, noisy signals about their opponents' value. Even though theoretically such information about opponents' value has no strategic use in the SPA, it provides us with a convenient instrument to change bidders' perception about the "strength" (i.e., the value) of their opponent. We argue that the empirical relationship between the incidence and magnitude of overbidding and bidders' perception of the strength of their opponent provides the key to understand whether overbidding in second price auctions are driven by "spite" motives or by the "joy of winning." The experimental data show that bidders are much more likely to overbid, though less likely to submit large overbid, when they perceive their rivals to have similar values as their own. We argue that this empirical relationship is more consistent with a modified "joy of winning" hypothesis than with the "spite" hypothesis. However, neither of the non-standard preference explanations are able to fully explain all aspects of the experimental data, and we argue for the important role of bounded rationality. We also find that bidder heterogeneity plays an important role in explaining their bidding behavior.Overbidding, Second price auctions, Spite, Joy of winning, Bounded rationality

Strategic Implications of Uncertainty Over One’s Own Private Value in Auctions

Suppose a bidder must decide whether and when to incur the cost of estimating his own private value in an auction. This can explain why a bidder might increase his bid ceiling in the course of an auction, and why a bidder would like to know the private values of other bidders. It also can explain sniping — flurries of bids at the end of auctions with deadlines — as the result of other bidders trying to avoid stimulating the uninformed bidder to examine his value.

Auditing and property rights

This is the official published version. Copyright @ 2004 RANDThird-party audit provides incentives to an agent whose actions affect the value of an asset. When audit intensity and outcome are unverifiable, we show that with interim-participation constraints the optimal mechanism may use only the auditor's report, disregarding the agent's information. Furthermore, the auditor obtains the asset and the agent a monetary compensation, when a high asset value is reported. This suggests regulating renewable resources or utility networks by giving entrants the option to buy the right to use the asset at a predetermined price, and financially rewarding incumbents for good performance.The second author used financial support of the Communaute francaise de Belgique (projet ARC 98/03-221) and EU TMR Network contract no.

Optimal Auctions with Information Acquisition

This paper studies optimal auction design in a private value setting with endogenous information acquisition. First, we develop a general framework for modeling information acquisition when a seller wants to sell an object to one of several potential buyers who can each gather information about their valuations prior to participation. We then show that under certain conditions, standard auctions with a reserve price remain optimal, but the optimal reserve price lies between the mean valuation and the standard reserve price in Myerson (1981). We provide sufficient conditions under which the value of information to the seller is positive, and also characterize the necessary and sufficient conditions under which equilibrium information acquisition in private value auctions is socially excessive. The key to the analysis is the insight that buyer incentives to acquire information become stronger as the reserve price moves toward the mean valuation.optimal auctions, information acquisition, rotation order, informational efficiency

Optimal Auctions with Simultaneous and Costly Participation

We study the optimal auction problem with participation costs in the symmetric independent private values setting, where bidders know their valuations when they make independent participation decisions. After characterizing the optimal auction in terms of participation cutoffs, we provide an example where it is asymmetric. We then investigate when the optimal auction will be symmetric/asymmetric and the nature of possible asymmetries. We also show that, under some conditions, the seller obtains her maximal profit in an (asymmetric) equilibrium of an anonymous second price auction. In general, the seller can also use non-anonymous auctions that resemble the ones that are actually observed in practice.

Reputation, Competition, and Entry in Procurement

Based on my recent work with several co-authors this paper explores the relationship between discretion, reputation, competition and entry in procurement markets. I focus especially on public procurement, which is highly regulated for accountability and trade reasons. In Europe regulation constrains the use of past performance information to select contractors while in the US its use is encouraged. I present some novel evidence on the benefits of allowing buyers to use reputational indicators based on past performance and discuss the complementary roles of discretion and restricted competition in reinforcing relational/reputational forces, both in theory and in a new empirical study on the effects restricted rather than open auctions. I conclude reporting preliminary results form a laboratory experiment showing that reputational mechanisms can be designed to stimulate rather than hindering new entry.Accountability; Discretion; Entry; Incomplete contracts; Limited enforcement; Past performance; Procurement; Quality; Relational contracts; Reputation; Restricted auctions.

Why Do Sellers (Usually) Prefer Auctions?

We compare the most common methods for selling a company or other asset when participation is costly: a simple simultaneous auction, and a sequential process in which potential buyers decide in turn whether or not to enter the bidding. The sequential process is always more efficient. But pre-emptive bids transfer surplus from the seller to buyers. Because the auction is more conducive to entry - precisely because of its inefficiency - it usually generates higher expected revenue. We also discuss the effects of lock-ups, matching rights, break-up fees (as in takeover battles), entry subsidies, etc.Auctions, jump bidding, sequential sales, procurement, entry
