Reputation and adverse selection: theory and evidence from eBay

How can a marketplace introduce mechanisms to overcome inefficiencies caused by adverse selection? In this article, I use a unique data set that follows eBay sellers to show that reputation is a major determinant of price variations. I develop a model of sellers' dynamic behavior where sellers have heterogeneous qualities unobservable by buyers. Using reputation as a signal of quality, I structurally estimate the model to uncover buyers' utility and sellers' costs and underlying qualities. I show that removing the reputation mechanism increases low‐quality sellers' market share, lowers prices, and consequently reduces sellers' profit by 66% and consumer surplus by 35%.     

Information, Search, and House Prices: Revisited

Buyers pay different prices for nearly identical homes. One explanation for this is that housing markets are thin, resulting in price bargaining between sellers and buyers. If the relative bargaining power of buyers varies, so will sales prices. One hypothesis is that the relative bargaining strength of buyers coming from outside the local market relative to that of local residents is weak, because distant buyers have high search costs and may know less about the nuances of the local market. Our results, based upon a large number of single-family home transactions from the state of Florida, lend support to this hypothesis. Another related hypothesis is that buyers?? price expectations are anchored to prices they were accustomed to at their previous residence. Hence, if they come from high price markets they will tend to pay more for their new home. This hypothesis is also supported by our results.     

Inflation and Welfare in Retail Markets: Prior Production and Imperfectly Directed Search

This paper considers the effect of monetary policy and inflation on retail markets: goods are dated and produced prior to being retailed; buyers direct their search on price and general quality; buyers’ match‐specific tastes are private information. Sellers set the same price for all buyers, some of whom do not value the good highly enough to buy it. The market economy is typically inefficient as a social planner would have the good consumed. Under free entry of sellers, the Friedman rule is optimal policy. When the upper bound on the number of participating sellers binds, moderate levels of inflation can be welfare improving.     

Why should anyone be led by you?

We all know that leaders need vision and energy, but after an exhaustive review of the most influential theories on leadership--as well as workshops with thousands of leaders and aspiring leaders--the authors learned that great leaders also share four unexpected qualities. The first quality of exceptional leaders is that they selectively reveal their weaknesses (weaknesses, not fatal flaws). Doing so lets employees see that they are approachable. It builds an atmosphere of trust and helps galvanize commitment. The second quality of inspirational leaders is their heavy reliance on intuition to gauge the appropriate timing and course of their actions. Such leaders are good "situation sensors"--they can sense what's going on without having things spelled out for them. Managing employees with "tough empathy" is the third quality of exceptional leadership. Tough empathy means giving people what they need, not what they want. Leaders must empathize passionately and realistically with employees, care intensely about the work they do, and be straightforward with them. The fourth quality of top-notch leaders is that they capitalize on their differences. They use what's unique about themselves to create a social distance and to signal separateness, which in turn motivates employees to perform better. All four qualities are necessary for inspirational leadership, but they cannot be used mechanically; they must be mixed and matched to meet the demands of particular situations. Most important, however, is that the qualities encourage authenticity among leaders. To be a true leader, the authors advise, "Be yourself--more--with skill."     

Word-of-mouth communication,noise-driven volatility,and public disclosure

This paper examines how a firm adjusts its disclosure quality in response to technological innovations that improve investors' private information. We show that more precise private information can endogenously amplify supply shocks and, hence, increase noise-driven (or non-fundamental) price volatility. We study how the firm reacts to such changes and derive a necessary and sufficient condition under which the firm improves its disclosure quality when investors are informed with better private signals. We then apply our model to study investors' private word-of-mouth communication. Our analysis highlights a “dark side” of word-of-mouth communication and a call for better public disclosure even if private communication is assumed to be unbiased and truthful. We provide empirical predictions regarding how price volatility, market depth, and firms’ disclosure qualities would change as technological innovations, such as social media, facilitate information sharing among investors.     

Search Costs,Behavioral Biases,and Information Intermediary Effects

In many markets, buyers, sellers, and their agents have differential information about the quality of heterogeneous assets. We study negotiated transaction prices in the commercial real estate market, which is characterized by heterogeneous assets, illiquidity, and highly segmented local markets, all of which increase the importance of asymmetric information in negotiated pricing outcomes. Using 114,588 industrial, multi-family and office sale transactions that occurred during 1997–2011, we document that distant commercial real estate buyers pay, on average, premiums of 4 % to 15 % relative to local buyers, controlling for individual property characteristics as well as time fixed-effects. We also examine the extent to which the sources of these observed premiums are a product of higher search costs/information asymmetry problems associated with distance (search cost channel) or a result of reference-dependence preference/anchoring based on the price levels in the investors’ local market (behavioral biases channel). Our results suggest the observed price premiums are explained by distant investors who face higher search costs and are at an information disadvantage compared to investors located in closer proximity to the property. In contrast, anchoring plays a more muted role in explaining observed premiums. The use of an intermediary (broker) increases, on average, the acquisition prices of buyers and decreases the disposition prices of sellers by 3 % to 8 %. This result is consistent with the incentive real estate agents have to convince sellers to dispose of their properties too quickly and to convince buyers to search less and therefore pay higher prices.     

Catastrophe Bonds,Reinsurance, and the Optimal Collateralization of Risk Transfer

Catastrophe bonds feature full collateralization of the underlying risk transfer and thus abandon the reinsurance principle of economizing on collateral through diversification of risk transfer. Our analysis demonstrates that this feature places limits on catastrophe bond penetration, even if the structure possesses frictional cost advantages over reinsurance. However, we also show that catastrophe bonds have important uses when buyers and reinsurers cannot contract over the division of assets in the event of insolvency and, more generally, cannot write contracts with a full menu of state‐contingent payments. In this environment, segregation of collateral—in the form of multiple reinsurance companies, as well as catastrophe bond vehicles—can ameliorate inefficiencies due to reinsurance contracting constraints by improving welfare for those exposed to default risk. Numerical simulation illustrates how catastrophe bonds improve efficiency in market niches with correlated risks, or with uneven exposure of buyers to reinsurer default.     

Does being a jerk work? Examining the effect of aggressive risk communication in the context of science blogs

Understanding aggressive risk communication is important because many scientists use this approach and we know little about its effects. Two studies were conducted to assess the effect of exposure to aggressive risk communication by a scientist on respondents’ perceptions of risk communication quality, supportive behavior (i.e. forwarding the communication), risk communicator likability, and overall views about scientists. Perceived aggressiveness (studies 1–2) and expectation violation (study 2) were considered as mediators. Analyses suggest both direct and indirect negative effects of aggressive risk communication in the case of likability but potentially positive effects in terms of evaluating the message quality. Moreover, expectation violation provided one possible explanation for the effect of aggression.     

Trade Credit Terms: Asymmetric Information and Price Discrimination Evidence From Three Continents

Abstract:   Trade credit terms offer firms contractual solutions to informational asymmetries between buyers and sellers. The credit period permits buyers to reduce uncertainty concerning product quality prior to payment, while the seller can reduce uncertainty concerning buyer payment intentions by prescribing payment before/on delivery or through two‐part payment terms and other mechanisms. Variation in trade credit terms also offers firms price discriminating opportunities. This study, drawing on the responses of 700 large firms in the US, UK and Australia, explores trade credit terms through the twin objectives of reducing information asymmetries and discriminatory pricing. Support is found for both theories.     

Price,quality, and reputation: evidence from an online field experiment

We examine the link between price, quality, seller claims, and seller reputation in Internet auctions. After purchasing actual baseball cards and having them professionally graded, we find that some buyers in the online graded market are misled by incredible claims of quality. They pay higher prices but do not receive better quality and, in fact, are defrauded more often. Online seller reputation is effective for identifying good‐faith sellers. But conditional on completed auctions, reputable sellers do not provide better quality. Evidence also suggests that high‐claim sellers target less‐experienced buyers. We attribute these patterns to two loopholes in the eBay rating system. We benefited from the comments of Austan Goolsbee, Raphael Thomadsen, John Shea, Dan Vincent, David Reiley, Larry Ausubel, Peter Cramton, V. Joseph Hotz, Jeff Smith, Jimmy Chan, Vincent Crawford, Mark Duggan, and attendees at numerous seminars and conferences. We are particularly grateful to Seth Sanders and John List for their constructive advice at the early stage of the research, to Timothy Bresnahan, Rachel Kranton, and Thomas Hubbard for their detailed suggestions in reshaping earlier versions, and to Editor Ariel Pakes and two anonymous referees for their careful readings. Special thanks to eight friends who acted as our agents in purchasing baseball cards in retail markets, and to numerous sports card store owners who shared their insights on the sportscard industry. Excellent research assistance from Randy Alexander Moore and Krzysztof Fizyta is gratefully acknowledged. Any remaining errors are ours.     

Short selling,margin trading,and the incorporation of new information into prices

Utilizing daily data on Chinese stocks' short selling and margin trading activities and intraday stock trade and quote data, we find a positive association between the degree of information efficiency of stock prices and the intensity of short selling and margin trading. Short selling (margin buying) escalates during the 5 days immediately before significant negative (positive) information events, which suggests short sellers (margin buyers) anticipate forthcoming news. Using the adverse selection component of the bid–ask spread as a proxy, we find that short selling and margin trading are associated with an improved information environment. Taken together, our empirical evidence supports the conjecture that short selling and margin trading in the Chinese market help stock prices incorporate new information more efficiently. Utilizing the unique Chinese regulation, we also examine the role of brokerages authorized for such trading and document a non-linear relation between pricing efficiency and the number of authorized brokerages.     

Leverage,governance and wealth effects of asset purchasers

We examine a sample of 670 firms that announce asset purchases. We hypothesize that buyer announcement returns should be higher in the presence of better monitoring and better governance. Consistent with the monitoring hypothesis, we find that buyers with higher private debt make purchase decisions that increase shareholder value. Consistent with the governance hypothesis, we find that returns are higher for buyers that have lower antitakeover provisions in place. Consistent with the managerial discretion hypothesis, buyer announcement-period returns increase with buyer leverage. Consistent with the liquidity hypothesis, we find that announcement-period returns decrease with the seller's Z-score, suggesting that buyers benefit from the lower liquidity of assets sold by sellers with lower debt capacity and higher financial distress. We also find that buyer announcement-period returns are directly related to their operating performance in the post-purchase year.     

An Exploration of Competitive Signalling Equilibria with “Third Party” Information Production: The Case of Debt Insurance

In markets in which sellers know more about product quality than buyers, but cannot convey their superior information either by directly issuing costly signals of the Spence type or by successfully funding the production of information, I suggest another way in which the informational asymmetry problem can be resolved; a third party can produce the necessary information at a cost and use it to price a service consumed by the sellers. Buyers can then observe a seller's choice of service consumption level and be well informed in equilibrium. In this framework I construct a model in which a borrower's choice of insurance coverage signals its default probability to lenders, and explore the properties of the resulting signalling equilibrium in a variety of cases.

Understanding in‐house transactions in the real estate brokerage industry

About 20% of residential real estate transactions in North America are in‐house transactions, for which buyers and sellers are represented by the same brokerage. We examine to what extent in‐house transactions are explained by agents' strategic incentives as opposed to matching efficiency. Using home transaction data, we find that agents are more likely to promote internal listings when they are financially rewarded and such effect becomes weaker when consumers are more aware of agents' incentives. We further develop a structural model and find that about one third of in‐house transactions are explained by agents' strategic promotion, causing significant utility loss for home buyers.     

多客户审计、审计公司组织形式与审计失败

本文通过建立审计质量的二次函数模型,分析了不同组织形式的审计公司在同时审计多个客户时,其审计报告的外部性对审计失败的影响。研究结果表明:1)在有限合伙制和赔偿机制完善的前提下,随着客户数量的增多,审计公司的审计质量上升,发生审计失败的概率下降;2)赔偿额越高,审计公司的审计质量也越高,其审计失败的概率降低;3)有限合伙制是一种较好的组织形式;4)审计师的诚信度越高,审计公司审计失败的概率越低;5)审计市场集中度越高,整个审计市场的失败概率越低。由此,本文认为建立有限合伙制、实施赔偿机制、提高审计师的诚信度和审计市场的集中度是提高审计质量和降低审计失败的有效途径。     

Speed of Issuance,Lender Specialization,and the Rise of the 144A Debt Market

Using a large sample of convertible and straight debt issues in the public, 144A, and bank loan markets from 1991 to 2004, we find that the 144A market has risen largely at the expense of the nonshelf public market, the overwhelming majority of the 144A issues are subsequently registered, and straight debt issuers with the highest credit quality and transparency tend to use the shelf public market. Our findings suggest that firms’ preference for speed of issuance drives the growth of the 144A market, and banks and qualified institutional buyers have advantages over public lenders in handling credit risk and information asymmetry.     

The private placement of bank equity

This paper investigates the role of private placements of common stock as a source of bank capital. Our results show that information asymmetry problems that typically attend new offers of bank equity are mitigated in the private placement process. Moreover buyers of privately placed common stock seem to provide a quality certification of capital deficient bank holding companies. Our evidence is also consistent with the notion that buyers of privately placed common stock provide a monitoring service that aligns the interest of the bank's managers and shareholders. Finally, we find no evidence that private placements are predominately motivated by incumbent management's attempts to sell equity to a friendly buyer at the expense of the bank's current shareholders.     

Stated and revealed investment decisions concerning retail structured products

We analyze the investment behavior of private clients with regard to retail structured products. To ascertain their stated and revealed preferences, we use a questionnaire and a field experiment. The real product issued in the field experiment is comparable to the hypothetical product in the questionnaire in terms of both payoff and communication. We find that a product described in simple words strongly motivates people to invest in structured products for the first time, and also eliminates gender differences. However, the real product attracts far fewer first-time buyers than we expected from the questionnaire results.     

Financial reporting quality,debt maturity and investment efficiency

This study, conducted with a sample of Spanish listed companies during the period 1998–2008, examines the role of financial reporting quality and debt maturity in investment efficiency. The results show that financial reporting quality mitigates the overinvestment problem. Likewise, lower debt maturity can improve investment efficiency, reducing both overinvestment and underinvestment problems. We further find that financial reporting quality and debt maturity are mechanisms with some degree of substitution in enhancing investment efficiency: firms with lower (higher) use of short-term debt, exhibit higher (lower) financial reporting quality effect on investment efficiency.
