Auctions with Endogenous Initiation

We study initiation of takeover auctions by potential buyers and the seller. A bidder's indication of interest reveals that she is optimistic about the target. If bidders' values have a substantial common component, as in takeover battles between financial bidders, this effect disincentivizes bidders from indicating interest, and auctions are seller-initiated. Conversely, in private-value auctions, such as battles between strategic bidders, equilibria can feature both seller- and bidder-initiated auctions, with the likelihood of the latter decreasing in commonality of values and the probability of a forced sale by the seller. We also relate initiation to bids and auction outcomes.     

Is There One Best Way to Sell a Company? Auctions Versus Negotiations and Controlled Sales1

For managements and boards that have decided that the value‐maximizing choice is to sell their companies, the board must then address another important question: what is the best way to sell the company? Should they use a wide‐ranging auction that seeks to attract the largest number of bidders, exclusive negotiation with a single bidder, or a “controlled sale” with a limited group of potential buyers? In a much cited 1996 article in the American Economic Review called “Auctions Versus Negotiations,” economists Jeremy Bulow and Paul Klemperer argued that there is “no merit in arguments that negotiation should be restricted to one or a few bidders to allow the seller to maintain control of the negotiating process.” But in their series of studies of the corporate M&A sales process over the past five years, the authors of this article have come to a very different conclusion. Contrary to the conventional wisdom, wide‐ranging auctions that seek the greatest number of bidders are far from the dominant approach. Roughly half of the large M&A deals investigated by the authors were accomplished through negotiations with single bidders. At the same time, full‐fledged auctions accounted for only about half of the deals involving multiple bidders, while the other half were classified as controlled sales aimed at a small number of carefully selected potential buyers. In their attempt to explain this preference for negotiations and controlled sales over auctions in M&A sales, the authors draw extensive parallels with the market for initial public offerings. As in the “bookbuilding” approach that now dominates the IPO process in virtually all global capital markets, the decision to limit the number of bidders through either negotiations or controlled sales appears to have the advantage of eliciting more aggressive bids from the “most qualified” buyers. Or, to put this another way, auctions appear to have the effect of discouraging such buyers from participating in the process.     

The overconfidence of investors in the primary market

We analyze the investment performance of 6993 investors bidding in 77 discriminatory IPO auctions in the Taiwan stock market between January 1996 and April 2000, and find that frequent bidders in these auctions have lower returns than infrequent bidders. The frequent bidders bid too aggressively and evaluate the IPO firms too optimistically, resulting in inferior performance. Despite being quite successful in their first few auction bids, the returns for frequent investors are gradually reduced in subsequent auctions. The multivariate model and the analysis of the possibility of perverse incentives of brokerage firms suggest that our findings cannot be explained by rational hypotheses, whereas in contrast, the theories on overconfidence and self-attribution bias can explain the increase in bidding frequency and the deterioration in return performance for bidders in IPO auctions.     

Estimation in English auctions with unobserved heterogeneity

We propose a framework for identification and estimation of a private values model with unobserved heterogeneity from bid data in English auctions, using variation in the number of bidders across auctions, and extend the framework to settings where the number of bidders is not cleanly observed in each auction. We illustrate our method on data from eBay Motors auctions. We find that unobserved heterogeneity is important, accounting for two thirds of price variation after controlling for observables, and that welfare measures would be dramatically misestimated if unobserved heterogeneity were ignored.     

Multiple Unit Auctions and Short Squeezes

This article develops a theory of multiunit auctions where shortsqueezes can occur in the secondary market. Both uniform anddiscriminatory auctions are studied and bidders can submit multiplebids. We show that bidders with short and long preauction positionshave different valuations in an otherwise common value setting.Discriminatory auctions lead to more short squeezing and higherrevenue than uniform auctions, ceteris paribus. Asymptotically,as the auction size approaches infinity, the two formats leadto equivalent outcomes. Shorts employ more aggressive equilibriumbidding strategies. Most longs strategically choose to be passive.Free riding on a squeeze by small, long players has no impacton these results, but affects revenue in discriminatory auctions.     

Does Joint Bidding Reduce Competition? Evidence from Hong Kong Land Auctions

This paper analyses firms’ bidding behavior in auctions for development land in Hong Kong. The real estate market in Hong Kong is considered to be oligopolistic as it is dominated by a few top real estate firms, which have strong financial strength/development capacity and large land banks. Joint bidding is used by other real estate firms (“large” firms) to pool resources/capital in order to compete with the top firms. We test whether joint bidding increases or decreases the level of competition in land auctions, using land auction data in Hong Kong from 1991 to 2011. We find that large real estate firms are more likely to be successful than top firms at auctions when bidding jointly. However, joint bidding/winning does not harm competition as reflected by the number of bids, bids per bidder and number of bidders. Land prices also increase significantly in auctions won by joint bidders or alliances of large developers. Our results suggest that joint bidding enhances competition by allowing large firms to act strategically by pooling their resources and act aggressively to compete with the top firms.

     

Buy‐out prices in auctions: seller competition and multi‐unit demands

Online auction sites often enable sellers to add a buy‐out price. In one‐shot auctions, this has been motivated by appeal to impatience or risk aversion. We offer additional justification in a dynamic model, by showing that an early seller has an incentive to use a buy‐out price, if a similar product is offered later by another seller, and bidders desire multiple objects. Revenue in the first auction increases, but revenue in the second auction decreases, as does the sum of revenues. The buy‐out price causes the auction sequence to become inefficient, because the first item may be awarded to a bidder who should have received none.     

An analysis of FDIC failed bank auctions

This paper examines whether the sales mechanism used by the FDIC in failed bank auctions results in wealth transfers from the FDIC to the acquiring banks. We test this hypothesis by examining the returns to winning bidders in FDIC auctions. We find positive abnormal returns to these bidders. More importantly, we find a negative and significant relation between the returns to winning bidders and the number of bidders participating in the auction. This evidence suggests that the FDIC's auction procedures do generate wealth transfers.     

Strategic Behavior and Underpricing in Uniform Price Auctions: Evidence from Finnish Treasury Auctions

We contribute to the debate on the optimal design of multiunit auctions by developing and testing robust implications of the leading theory of uniform price auctions on the bid distributions submitted by individual bidders. The theory, which emphasizes market power, has little support in a data set of Finnish Treasury auctions. A reason may be that the Treasury acts strategically by determining supply after observing bids, apparently treating the auctions as a repeated game between itself and primary dealers. Bidder behavior and underpricing react to the volatility of bond returns in a way that suggests bidders adjust for the winner's curse.     

Field experiments on the effects of reserve prices in auctions: more Magic on the Internet

I present experimental evidence on the effects of minimum bids in first‐price, sealed‐bid auctions. The auction experiments manipulated the minimum bids in a preexisting market on the Internet for collectible trading cards from the game Magic: the Gathering. I examine a number of outcomes, including the number of participating bidders, the probability of sale, the levels of individual bids, and the auctioneer's revenues. The benchmark theoretical model is one with symmetric, risk‐neutral bidders with independent private values. The results verify a number of the predictions concerning equilibrium bidding. Many bidders behave strategically, anticipating the effects of the reserve price on others' bids.     

The Winner's Curse and Bidder Competition in Acquisitions: Evidence from Failed Bank Auctions

This study examines the effect of bidder competition in acquisitions. We use predictions from auction theory to test whether acquirers of failed banks overpay (the “winner's curse”) when bidding in FDIC sealed-bid purchase and assumption (P&A) transactions (auctions). The empirical results indicate that winning bids tend to increase as the number of competitors increases, as predicted by theory. We also find that bid levels of all bidders increase with increased competition, which is consistent with bidders' failing to adjust for the winner's curse in a common value auction setting. However, additional tests using winning bids only are consistent with both a common value and a private values model, so this result should be interpreted with caution.     

China's land market auctions: evidence of corruption?

In China, urban land is allocated by leasehold sales by local officials. Attempting to end widespread corruption, the government now requires sales to be conducted publicly, by either English or “two‐stage” auctions. However, corruption persists through the choice of auction format and preauction side deals between favored bidders and local officials. Two‐stage auctions have a first stage where favored developers signal that auctions are “taken,” deterring entry of other bidders. Empirics show that both sales prices and competition are significantly less for two‐stage than English auctions. Selection on unobserved property characteristics is positive: officials divert hotter properties to two‐stage auctions.     

Bounds on revenue distributions in counterfactual auctions with reserve prices

Measuring auction revenues under counterfactual reserve prices or formats requires knowledge of distributions of bidders' values and private signals. This poses a challenge when bids are observed from first‐price, common‐value auctions. I bound counterfactual revenue distributions without imposing parametric restrictions on the model structure. Using data from U.S. municipal bond auctions, I find first‐price and second‐price auctions under optimal reserve prices lead to little improvement in revenues over existing first‐price formats. The number of bidders has a more significant impact on revenues in optimal auctions. I also find invoking an incorrect assumption of private values in counterfactual analyses results in small errors in predicting revenues from optimal second‐price auctions.     

Underpricing and Market Power in Uniform Price Auctions

In uniform auctions, buyers choose demand schedules as strategiesand pay the same "market clearing" price for units awarded.Despite the widespread use of these auctions, the extant theoryshows that they are susceptible to arbitrarily large underpricing.We make a realistic modification to the theory by letting prices,quantities, and bids be discrete. We show that underpricingcan be made arbitrarily small by choosing a sufficiently smallprice tick size and a sufficiently large quantity multiple.We also show how one might improve revenues by modifying theallocation rule. A trivial change in the design can have a dramaticimpact on prices. Our conclusions are robust to bidders beingcapacity constrained. Finally, we examine supply uncertaintyrobust equilibria.     

Strategic and Financial Bidders in Takeover Auctions

Using data on auctions of companies, we estimate valuations (maximum willingness to pay) of strategic and financial bidders from their bids. We find that a typical target is valued higher by strategic bidders. However, 22.4% of targets in our sample are valued higher by financial bidders. These are mature, poorly performing companies. We also find that (i) valuations of different strategic bidders are more dispersed and (ii) valuations of financial bidders are correlated with aggregate economic conditions. Our results suggest that different targets appeal to different types of bidders, rather than that strategic bidders always value targets more because of synergies.     

Buy Smart,Time Smart: Are Takeovers Driven by Growth Opportunities or Mispricing?

Excessively high pricing by bidders and targets can be explained by new growth opportunities created by the merger or by irrational overpricing in financial markets. We integrate both explanations through a new decomposition of firm value and investigate whether it is “true” growth value or mispricing that drives takeover waves. We find that “bidders buy smart.” Bidders primarily have high market values because of growth opportunities and overpricing, and select targets that are less overpriced with similar fundamental growth value. Bidders also seem to “time smart.” Takeover activity increases when bidders are more overpriced, in order to cushion against price corrections.     

Information feedback in first price auctions

I apply the notion of a self‐confirming equilibrium (SCE) to study how feedback in first price auctions influences bidders' perceptions about their strategic environment, and consequently their bidding behavior. In a private values setting, revealing the two highest bids at the end of each auction is sufficient for bidders to have correct beliefs (justifying the assumption of Nash equilibrium). In contrast, in every symmetric SCE of a symmetric, affiliated, private values model, bidding strategies and revenue are (weakly) higher if only the highest bid is revealed. I also consider interdependent valuations and discuss implications for the empirical auction literature.     

RULE CHANGES AND UNCERTAINTY IN DISCRIMINATORY AND UNIFORM PRICE AUCTIONS

The auction literature indicates that uncertainty about the value of auctioned goods increases underpricing in discriminatory price auctions. Such uncertainty has a smaller effect on uniform price auctions because the pricing rule aggregates bidders' information. We find that uncertainty resulting from inexperience with an auction mechanism has similar effects. Using initial public offering (IPO) data from Japan and Israel, we find that average underpricing increases temporarily in Japan's discriminatory price auctions after changes in the auction rules, which suggests that bidders reduce their bids in response to uncertainty. Underpricing in Israel's uniform price auctions is not affected by rule changes.     

Not knowing the competition: evidence and implications for auction design

In a government auction program where first-price auctions generate significantly higher revenue than English auctions, I document evidence that bidders are uncertain about the number of auction entrants. Motivated by additional data evidence, I estimate a structural model of auctions in which rivals' participation is stochastic, allowing for bidders' risk aversion and asymmetry. Counterfactual simulations reveal that bidders' uncertainty about the number of entrants, combined with risk aversion, substantially softens the revenue impact of low competition in first-price auctions. This explains the observed revenue patterns and uncovers an empirically important reason for sellers to favor first-price auctions over English auctions.
