Properties of scoring auctions

This article studies scoring auctions, a procedure commonly used to buy differentiated products: suppliers submit offers on all dimensions of the good (price, level of nonmonetary attributes), and these are evaluated using a scoring rule. We provide a systematic analysis of equilibrium behavior in scoring auctions when suppliers' private information is multidimensional (characterization of equilibrium behavior and expected utility equivalence). In addition, we show that scoring auctions dominate several other commonly used procedures for buying differentiated products, including menu auctions, beauty contests, and price‐only auctions with minimum quality thresholds.     

Strategic bidding in multi‐unit auctions with capacity constrained bidders: the New York capacity market

This article employs a simple model to describe bidding behavior in multi‐unit uniform price procurement auctions when firms are capacity constrained. Using data from the New York City procurement auctions for power generating capacity, I find that firms use simple bidding strategies to coordinate on an equilibrium that extracts high rents for all bidders. I show theoretically and empirically that the largest bidder submits the auction clearing bid. All other bidders submit inframarginal bids that are low enough to not be profitably undercut. Inframarginal bidders decrease their bids as the pivotal firm's capacities and its profits of undercutting increase.     

Mixed strategies in discriminatory divisible‐good auctions

We introduce the concept of an offer distribution function to analyze randomized offer curves in multiunit procurement auctions. We characterize mixed‐strategy Nash equilibria for pay‐as‐bid auctions where demand is uncertain and costs are common knowledge, a setting for which pure‐strategy supply function equilibria typically do not exist. We generalize previous results on mixtures over horizontal offers as in Bertrand‐Edgeworth games and also characterize novel mixtures over partly increasing supply functions. We show that the randomization can cause considerable production inefficiencies.     

Endogenous asymmetry in a dynamic procurement auction

We show how to numerically solve for a Markov‐perfect equilibrium of a dynamic auction game where a procurer repeatedly purchases construction services from capacity‐constrained firms. We find that the procurer is best off scheduling frequent auctions for small project sizes. Otherwise, firm capacity utilization rates become larger and more asymmetric, which softens competition and increases procurement costs. We also find that forward‐looking bidding dampens the competition‐softening effects of asymmetry: farsighted firms compete more intensely than myopic ones. This can undermine the goal of a bid‐preference‐style affirmative action program: more farsighted firms respond less to the asymmetry induced via bid preferences.     

Prizes and lemons: procurement of innovation under imperfect commitment

The literature on research and development contests implicitly assumes that contestants submit their innovation regardless of its value. This ignores a potential adverse selection problem. The present article analyzes the procurement of innovations when the procurer cannot commit himself to never bargain with innovators who bypass the contest. We compare fixed‐prize tournaments with and without entry fees, and optimal scoring auctions with and without minimum score requirement. Our main result is that preventing bypass is more costly in the optimal auction, and the optimal fixed‐prize tournament is more profitable than the optimal auction.     

Specification and negotiation in incomplete contracts

We investigate contractors' bargaining power and holdup on buyers in procurement auctions of incomplete contracts held by California Department of Transportation. Using a model where contractors bid competitively in response to a buyer's choice of initial contract design, we infer the contractors' costs and bargaining power from the bids and transfers negotiated after the auction. We find that the contract winners have substantial bargaining power in post‐auction negotiation. The average holdup on the buyer is about 20% of project costs. Counterfactual cost‐plus contracts would reduce the buyer's surplus in 72% of the projects, with an average reduction over $382,000.     

Subcontracting and competitive bidding on incomplete procurement contracts

This article examines the impact of incomplete contracts on subcontracting and the design of procurement auctions. I estimate the effect of ex post contract revisions on unit costs for both subcontracted and in‐house performed work items on bridge projects procured by the California Department of Transportation. I model a scoring auction showing how ex post revisions skew bidding decisions and estimate unit costs from bid data using the method of sieve estimation. The results highlight the cost implications of incomplete contracting frictions, subcontracting decisions, and bidding distortions. In conclusion, I propose alternative auction mechanisms that could improve outcomes.     

Does Public E-Procurement Deliver What It Promises? Empirical Evidence from Turkey

This article empirically investigates the economic effects of public e-procurement (PEP) adoption. We use a unique data set provided by the Public Procurement Authority of Turkey that covers all government procurement auctions for the years 2004–12, 588,454 auctions. We conclude that PEP adoption had adverse effects. The number of firms submitting bids in procurement auctions is significantly lower after PEP adoption. The procurement costs are significantly higher after PEP. These results suggest that policy makers should eliminate barriers to e-procurement adoption to gather the intended results of PEP.     

Regulating bidder participation in auctions

Regulating bidder participation in auctions can potentially increase efficiency compared to standard auction formats with free entry. We show that the relative performance of two such mechanisms, a standard first‐price auction with free entry and an entry rights auction, depends nonmonotonically on the precision of information that bidders have about their costs prior to deciding whether to participate in a mechanism. As an empirical application, we estimate parameters from first‐price auctions with free entry for bridge‐building contracts in Oklahoma and Texas and predict that an entry rights auction increases efficiency and reduces procurement costs significantly.     

IPO auctions and private information

IPO auctions, which provide an impartial way of determining IPO pricing and share allocations, offer a natural setting for examining whether institutional investors possess private information, and for measuring how valuable their information is. Analyzing detailed bidding data from Taiwan’s discriminatory (pay-as-bid) auctions, we find that, relative to retail investors, institutional investors tend to bid higher in auctions when IPO shares are more valuable, and that underpricing is larger in auctions with relatively higher institutional bids. These results imply that institutional investors are better informed about IPO value, and that they obtain higher information rents when they bid higher relative to retail investors. We estimate the value of institutional investors’ private information to be worth about 8.68% of return, which is the extra rate of return they command on their informational advantages over retail investors.     

Procurement with specialized firms

We analyze optimal procurement mechanisms when firms are specialized. The procurement agency has incomplete information concerning the firms' cost functions and values high quality as well as low price. Lower type firms are cheaper (more expensive) than higher type firms when providing low (high) quality. With specialized firms, distortion is limited and a mass of types earns zero profits. The optimal mechanism can be inefficient: types providing lower second‐best welfare win against types providing higher second‐best welfare. As standard scoring rule auctions cannot always implement the optimal mechanism, we introduce a new auction format implementing the optimal mechanism.     

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.     

Closing call auctions and liquidity

The present paper examines the impact of closing call auctions on liquidity. It exploits the natural experiment offered by the introduction of a closing call auction on the Australian Stock Exchange on 10 February 1997. The introduction of the closing call auction is associated with a reduction in trading volume at the close of continuous trading. However, bid‐ask spreads during continuous trading are largely unaffected by the introduction of the closing call auction. Therefore, closing call auctions consolidate liquidity at a single point in time without having any adverse effect on the cost of trading.     

National Culture and Takeover Contest Outcomes

We examine the effects of cultural differences on the outcome of takeover contests. Our main focus is on individuality, which we posit to have an effect on firm behavior in international takeover contests. In a sample of international acquisitions with bidders from multiple countries, we find that individuality positively relates to the probability of placing the winning bid. We further find that takeover contest winners with high individuality scores experience lower announcement returns. Our results are consistent with the literature that links individuality to overconfidence. Our evidence suggests that firms should control culture‐related behavioral biases in their mergers and acquisitions activity.     

The Beauty Contest and Short‐Term Trading

Short‐termism need not breed informational price inefficiency even when generating beauty contests. We demonstrate this claim in a two‐period market with persistent liquidity trading and risk‐averse, privately informed, short‐term investors and find that prices reflect average expectations about fundamentals and liquidity trading. Informed investors engage in “retrospective” learning to reassess inferences (about fundamentals) made during the trading game's early stages. This behavior introduces strategic complementarities in the use of information and can yield two stable equilibria that can be ranked in terms of liquidity, volatility, and informational efficiency. We derive implications that explain market anomalies as well as empirical regularities.     

Auctions versus negotiations: the effects of inefficient renegotiation

For the procurement of complex goods, the early exchange of information is important to avoid costly renegotiation. If the buyer can specify the main characteristics of possible design improvements in a complete contingent contract, scoring auctions implement the efficient allocation. If this is not feasible, the buyer must choose between a price‐only auction (discouraging early information exchange) and bilateral negotiations with a preselected seller (reducing competition). Bilateral negotiations are superior if potential design improvements are important, if renegotiation is very costly, and if the buyer's bargaining position is strong. Moreover, negotiations provide stronger incentives for sellers to investigate design improvements.     

Land Auctions with Budget Constraints

This paper tests for the effects of financial constraints on open-bid English land auction prices and bids. It is argued that bidders’ ability to pay, taken as capital resources and/or capital budget constraints, influence bids and final auction prices. While high capital resource developers may elect to bid more than optimal to win auctions, or bidders may elect to pool resources in joint bidding, budget constraints imposed by firm-specific financial variables on the other hand are expected to restrict bids. Land auction data in Hong Kong are used to test systematically these predictions. It is found that a firm’s age, the number of winners in a joint bid, and firm status in the market are positively related to prices, all factors which may be attributed to a firm’s ability to finance the auction price. Firm size, internal funds, financing cost, debt capacity and existing capital expenditure are also shown to affect bids submitted in land auctions: firm size and internal funds are positively related to bid prices; while constrained debt capacity, financing cost and existing capital expenditure lower bids. The results are consistent with predictions that a firm’s financial constraints, and thus its effect on capital budgets, are relevant factors in predicting land auction outcomes. More generally, these findings confirm that similar financial factors that constrain corporate capital investment also influence directly acquisition of assets at auctions.     

How Has Takeover Competition Changed Over Time?

Since the boom in takeovers in the 1980s, research in both law and financial economics has debated the role of takeover impediments such as poison pills, staggered boards, and state antitakeover laws. Have these impediments entrenched target management to the detriment of shareholders? Or have they increased the bargaining power of target boards of directors and left shareholders, if not better off, then at least unharmed? In their study published recently in the Journal of Corporate Finance, the authors provide new answers to these questions with a detailed analysis of takeover competition during the period 1981 through 2014. Using a random sample of 388 completed and withdrawn deals from this 34‐year period, the authors begin by confirming the already well‐documented increase in the use of takeover impediments over time. They then report evidence that takeover competition has not declined during this period. First of all, takeover premiums—the average percentage over market paid by acquirers to consummate transactions—have remained steady over time. Second, and the most striking of the authors' findings, is that the corporate auction process has “gone underground” since the 1980s. Although we now see fewer hostile attempts and publicly reported takeover bidding contests, the amount of competition for targets has remained largely unchanged when one takes account of “private” as well as public auctions—that is, contests that, as the authors discovered, included unidentified bidders. The authors view such a fundamental change in the takeover auction process as a response to the widespread growth of takeover impediments. In this sense, as Bill Schwert commented years ago, “hostile takeovers are less about shirking target management than about the bargaining tactics of targets and bidders.” Or as the authors put it, “the greater bargaining power provided by state laws and other takeover impediments has changed the manner in which takeover auctions are conducted,” but without greatly affecting the goal of economic efficiency that such transactions are designed to help bring about.     

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.     

Auctions of divisible goods: on the rationale for the treasury experiment

We compare a sealed-bid uniform-price auction (the Treasury'sexperimental format) with a sealed bid discriminatory auction(the Treasury's format heretofore), assuming the good is perfectlydivisible. We show that the auction theory that prompted theexperiment, which assumes single-unit demands, does not adequatelydescribe the bidding game for Treasury securities. Collusivestrategies are self-enforcing in uniform-price divisible-goodauctions. In these equilibria, the seller's expected revenueis lower than in equilibria of discriminatory auctions.
