Bidding to lose? Auctions with resale

A losing bidder can still purchase the prize from the winner after the auction. We show why a strong bidder may prefer to drop out of the auction before the price has reached her valuation and acquire the prize in the aftermarket: a strong bidder may be in a better bargaining position in the aftermarket if her rival won at a relatively low price. So it can be common knowledge that, in equilibrium, a weak bidder will win the auction and, even without uncertainty about relative valuations, resale will take place. The possibility of reselling to a strong bidder attracts weak bidders to participate in the auction and raises the seller's revenue.     

Tacit collusion and capacity withholding in repeated uniform price auctions

This article analyzes tacit collusion in infinitely repeated multiunit uniform price auctions in a symmetric oligopoly with capacity‐constrained firms. Under two popular definitions of the uniform price, when each firm sets a price‐quantity pair, perfect collusion with equal sharing of profit is easier to sustain in the uniform price auction than in the corresponding discriminatory auction. Moreover, capacity withholding may be necessary to sustain this outcome. Even when firms may set bids that are arbitrary finite step functions of price‐quantity pairs, in repeated uniform price auctions maximal collusion is attained with simple price‐quantity strategies exhibiting capacity withholding.     

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.     

Quote disclosure and price discovery in multiple-dealer financial markets

We examine the effects of price disclosure on market performancein a continuous experimental multiple-dealer market in whichseven professional market makers trade a single security. Thedealers trade with one another and with computerized informedand liquidity traders. Our key comparison is between fully publicprice queues (pretrade transparent market) and bilateral quoting(pretrade opaque). We find that opening spreads are wider andtrading volume is lower in the opaque markets due to highersearch costs there. More importantly, however, higher searchcosts also induce more aggressive pricing strategies, so thatprice discovery is much faster in the opaque markets.     

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.     

Inference on vertical contracts between manufacturers and retailers allowing for nonlinear pricing and resale price maintenance

We present a model of vertical contracts between manufacturers and retailers with nonlinear pricing strategies. Using home‐scan data on bottled water produced by manufacturers and sold by retail chains in France, we estimate a structural demand and supply model allowing for two‐part tariff contracts between manufacturers and retailers. Using price‐cost margins recovered from estimates of demand parameters, we select the best supply model by performing nonnested tests, and find that manufacturers use two‐part tariff contracts with resale price maintenance. We then perform counterfactual policy simulations that restrict the use of these vertical contracts and assess welfare effects under alternative scenarios.     

Stock price response to new‐CEO earnings news

New‐CEO earnings news exhibits asymmetric effects on stock prices. Stock prices rise more on good earnings news announced by firms with new CEOs compared with those with established CEOs. By contrast, stock prices tend to fall by a smaller amount on bad earnings news for new CEOs. Both the new‐CEO quality effect and the new‐CEO honeymoon effect are more pronounced for CEOs appointed during challenging situations. The new‐CEO quality effect is stronger for firms followed by fewer analysts, while the honeymoon effect is stronger for firms followed by more analysts – illustrating the importance of a transparent information environment.     

Long‐run price competition

We generalize the standard repeated‐games model of dynamic oligopolistic competition to allow for consumers who are long‐lived and forward looking. Each period leaves some residual demand to future periods and pricing in one period affects consumers' expectations about future prices. We analyze this setting for an indivisible durable good with price‐setting firms and overlapping cohorts of consumers. The model nests the repeated‐game model and the Coasian durable‐goods model as its two extreme cases. The analysis is mostly focused on constant‐price collusion but conditions for collusive recurrent sales are also identified.     

Welfare‐increasing third‐degree price discrimination

When demand functions in different markets are derived from distributions of reservation prices that differ only in their means, conditions exist such that third‐degree price discrimination leads to greater total output and greater total welfare. Welfare is higher with discrimination than with a uniform price when demand functions are derived from logistic distributions with different means. Welfare and consumer surplus are higher with discrimination for demands derived from a distribution related to the Pareto. In general, whether discrimination increases total output depends on demand being more convex in markets in which prices fall with discrimination than in those in which prices rise.     

The First‐ and Second‐Hand Effect of Analysts' Stock Recommendations: Evidence from the Swiss Stock Market

This paper empirically investigates the impact of both the first release of analysts' stock recommendations to a limited clientele and the subsequent dissemination of the same information in a major newspaper to a broader audience. For a sample of 1460 stock recommendations published in FuW, Switzerland's major financial newspaper, significant positive abnormal returns on the day of the original release of buy recommendations and on the day of publication in FuW are documented. Tests of the price pressure and information hypotheses reveal that analysts' recommendations contain new information, which is quickly incorporated in the stock prices on the first release of this information. In contrast, the statistically significant announcement effects associated with the subsequent publication can be primarily ascribed to price pressure in the underlying securities.     

Strategic design under uncertain evaluations: structural analysis of design‐build auctions

I investigate firms' competition over price and product design under uncertain design evaluations in the context of Design‐Build (DB) auctions. Reviewers' design evaluations contain uncertainty from a bidder's perspective, leading luck to dampen differences in the firms' chances of winning. I model bidders' behavior and show semiparametric identification of the model primitives. Uncertain design evaluations increase the expected price of design quality and exacerbate an auctioneer's uncertainty in auction outcomes. These effects are mostly due to changes in bidding strategies. Bid ranking swaps due to uncertain evaluations account for a small share of these effects.     

Stock price crash risk and internal control weakness: presence vs. disclosure effect

This study examines the stock price crash risk for a sample of firms that disclosed internal control weaknesses (ICW) under Section 404 of the Sarbanes‐Oxley Act (SOX). We find that in the year prior to the initial disclosures, ICW firms are more crash‐prone than firms with effective internal controls. This positive relation is more pronounced when weakness problems are associated with a firm's financial reporting process. More importantly, we find that stock price crash risk reduces significantly after the disclosures of ICWs, despite the disclosure itself signalling bad news. The above results hold after controlling for various firm‐specific determinants of crash risk and ICWs. Using an ICW disclosure as a natural experiment, our study attempts to isolate the presence effect of undisclosed ICWs from the initial disclosure effect of internal control weakness on stock price crash risk. In so doing, we provide more direct evidence on the causal relation between the quality of financial reporting and stock price crash risk.     

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.     

A retail benchmarking approach to efficient two‐way access pricing: no termination‐based price discrimination†

We study access pricing rules that determine the access prices between two networks as a linear function of marginal costs and (average) retail prices set by both networks. When firms compete in linear prices, there is a unique linear rule that implements the Ramsey outcome as the unique equilibrium, independently of underlying demand conditions. When firms compete in two‐part tariffs, there exists a class of rules under which firms choose the variable price equal to the marginal cost. Therefore, the regulator can choose among these rules to pursue additional objectives such as increasing consumer surplus or promoting socially optimal investment.     

An inverted U‐shaped crude oil price return‐implied volatility relationship

We examined the return–volatility relationship for USO ETF oil price return and CBOE Crude Oil ETF Volatility Index, OVX. The data for the USO and OVX covers the period covering May 11, 2007 to February 28, 2013. Our OLS regression results suggest evidence of regular feedback and leverage effects. When we employ linear quantile regression techniques, we find evidence of regular and inverse feedback effects. The inverse feedback effects being noticeable in the upper quantile region of the oil return distribution. There is also support for a regular leverage effect in USO prices. We also examined the return–volatility relationship using quantile regression copula methods for measuring the degree of asymmetry in the relationships between the oil price return and implied volatility. The results of the analysis indicate, first, that there exists a negative relationship between contemporaneous oil VIX and USO ETF oil returns. Second, that the relationship between oil returns and implied volatilities depends on the quartile at which the relationship is being investigated. Third, there exists an inverted U-shaped dependency relationship between returns and implied volatilities across quantiles. Fourth, though an inverted U-shape exists, the shape is different from those observed in stock markets.     

Increased mandated disclosure frequency and price formation: evidence from the 8-K expansion regulation

Review of Accounting Studies - Regulators claim that increased mandated disclosure frequency should lead to more efficient price formation. However, analytical models suggest that mandating...     

Compliance with IFRS disclosure requirements and individual analysts’ forecast errors

We investigate the relationship between analysts’ earnings forecast errors and firm compliance with the disclosure requirements of International Financial Reporting Standards (IFRS). Using a comprehensive disclosure index of selected IFRS for which previous research has indicated significant noncompliance, we develop an unweighted and an innovative weighted measure of IFRS disclosure compliance. We document that forecast error is negatively related to IFRS compliance, and that the magnitude of this effect is larger when controlling for analyst fixed effects. Our findings suggest that compliance with the disclosure requirements of IFRS reduces information asymmetry and enhances the ability of financial analysts to provide more accurate forecasts. Our findings also support the viewpoint that the extent of compliance with accounting standards is as important as the standards themselves. Our results are robust to alternative model specifications.     

The welfare effects of third‐degree price discrimination with nonlinear demand functions

The welfare effects of third‐degree price discrimination are analyzed when demand in one market is an additively shifted version of demand in the other market and both markets are served with uniform pricing. Social welfare is lower with discrimination if the slope of demand is log concave or the convexity of demand is nondecreasing in the price. The demand functions commonly used in models of imperfect competition satisfy at least one of these sufficient conditions.     

The effect of information disclosure on demand for high‐load insurance

Economists, regulators, and consumer protection agencies have highlighted the welfare losses for consumers who purchase high‐load insurance against modest stakes risks. Mandatory information disclosure is a potentially attractive public policy tool that might improve consumers' choices, but has not been widely tested in insurance settings. We conduct an incentive‐compatible insurance demand experiment, in which we manipulate the information disclosed to subjects. We test whether any of the three most commonly suggested disclosures affect insurance demand, disclosing either (1) the true probability of loss, (2) the contract's expected loss, or (3) the insurer's profit on the transaction. Similar to consumers in naturally occurring insurance markets, subjects in the laboratory demonstrate significant demand for high‐load insurance against modest stakes. However, we find no effect of any of the three disclosure treatments on subjects' insurance choices. We discuss the implications of our results for possible public policy initiatives in insurance markets.     

Demand for nondurable goods: a shortcut to estimating long‐run price elasticities

When consumers stockpile, static demand models overestimate long‐term price responses. This article presents a dynamic model of demand with consumer inventories and proposes a shortcut to estimate the long‐run price elasticities without having to solve the dynamic program. Using French data on food purchases, I find elasticities consistent with those that result from the full‐blown estimations found in the literature.
