Competition and the signaling role of prices

In a market where sellers are heterogeneous with respect to the quality of their good and are more informed than buyers, high quality sellers' chances to trade might depend on their ability to inform buyers about the quality of the goods they offer. We study how the strength of competition among sellers affects the ability of sellers of high quality goods to achieve communication by means of appropriate pricing decisions in the context of a market populated by a large number of strategic price-setting sellers and a large number of buyers. When competition among sellers is weak high quality sellers are able to use prices as a signaling device and this enables them to trade. By contrast, strong competition among sellers inhibits the role of prices as signals of high quality, and high quality sellers are driven out of the market.     

Experimenting with purchase history based price discrimination

Many purchases of differentiated goods are repeated, giving sellers the opportunity to engage in price discrimination based upon the shopper's previous behavior by either offering loyalty discounts to repeat buyers or introductory rates to new customers. Recent theoretical work suggests that loyalty discounts can be profitable to sellers when customer preferences are not stationary and sellers can pre-commit to prices for repeat buyers, but otherwise returning customers can be expected to pay the same or more than new buyers. This paper reports behavior in controlled laboratory experiments designed to empirically test the impact of these factors on pricing strategies. The results generally support the comparative static predictions of the theoretical model. When customer preferences are fixed over time, sellers attempt to lure customers from their rival. Price pre-commitment for repeat shoppers when buyer preferences vary over time resulted in modest loyalty pricing, but the discounts are not as prevalent as predicted as sellers rarely price below cost. Behaviorally, price pre-commitment to loyal customers is found to reduce prices overall.     

Queues, not just mediocrity: Inefficiency in decentralized markets with vertical differentiation

We analyze a dynamic, decentralized market with endogenous entry, where in each period the active sellers supply one unit of an indivisible service at varying degrees of quality. The customers that have entered the market are randomly matched with the active sellers and prices are set by (complete information) pair-wise bargaining. In its unique steady state, the market leads to an excess diversity of quality and customers may have to suffer costly delays. Notably, efficiency is not regained as per period delay costs disappear. We also show that setting minimal quality standards, such as licensing rules by a professional college, will improve welfare (and even Consumer Surplus), relative to the free market, whenever the inefficiency is caused by a large enough excess supply.     

Till death do us part…but not always: Six antecedents to a customer's relational preference in buyer-seller exchanges

Since its emergence in the early 1990s as marketing's newest paradigm or school of thought, research in the area of relationship marketing has been proliferating. From the customer's perspective, initial attempts to become lifelong partners with key sellers or suppliers were appealing. However, as these propositions multiply in number and carry with them increasing burdens in terms of time and commitment, customers are reticent to enter into long-lasting relationships with all sellers. In this paper, we consider relationship formation from the customers' perspective and examine the antecedents to a customer's preference for a relational exchange orientation versus a transactional exchange orientation. Our belief is that, depending upon a set of contextual factors surrounding the exchange, customers will opt for a relational orientation with suppliers in some cases and for a more transactional orientation in others.     

Platform competition with free entry of sellers

We study platforms setting access prices and commissions on revenues of sellers engaged in monopolistic competition with free entry, such as the app providers on the app stores of Apple and Android devices. The link between prices on different sides induces the platforms to redistribute all the commission revenues through lower access prices and to set the optimal commission rates from the point of view of consumers, taking into account the pass-through on the prices of sellers, the elasticities of demand and surplus for their services and the elasticity of entry with respect to profitability. We discuss the role of heterogeneous sellers, substitutability between sellers’s products and limitations of the basic alignment of interest due to direct channels for sellers and consumer myopia.     

Optimal Selling Mechanism,Auction Discounts and Time on Market

This article examines the optimal selling mechanism problem in real estate market using mean‐variance analysis and downside risk analysis. When sellers can choose between accepting the first offer above a reservation price or auctions (waiting an optimal and fixed time), sellers having higher risk aversion choose auctions and wait a fixed time while sellers having lower risk aversion choose an optimal reservation price and wait a random time. Positive auction discounts are compensated by reduced risks, and there exists a connection between liquidity risk and conditional auction discount. More (Fewer) sellers will choose to sell their houses through auctions in a hot (cold) market or when holding cost increases (decreases). When sellers choose auctions, sellers having higher risk aversion who have lower holding cost wait longer and obtain higher sale price. Loss‐averse sellers unanimously choose the mechanism of setting an optimal reservation price.     

Experimental Evidence on Product Adoption in the Presence of Network Externalities

The benefits accruing to a purchaser of a product due to the existing base of consumers of the same or compatible products are known as network externalities. This paper studies Katz and Shapiro's (1986) model of network externalities in an experimental setting. Two sellers choose prices for competing technologies sold to two groups of four buyers purchasing sequentially in two stages. The results are qualitatively consistent with Katz and Shapiro's equilibrium predictions. In certain sessions over three-quarters of first stage buyers purchase the more expensive technology anticipating that later arriving buyers will also buy this technology. In periods where a strong network has been established for a technology in the first stage, over 80 percent of second stage buyers buy that technology, even though in most cases it is priced higher. The data, however, differ from the point predictions of the model.     

Modelling the effect of buyer and seller power on the margins of commodity plastics

In the last decade, large sectors of the chemical and plastics industries in the U.S.A. and West Europe have suffered drastic declines in price and gross margin during periods of low use of industry capacity. This paper shows that the major changes in gross margin observed for some commodity plastics can be modelled successfully in terms of the balance between buyer power and seller power. These industries have visibility of prices and industry occupacity and comparable concentrations of sellers and important buyers. The modelling follows Burgess (1982) in expressing buyer and seller power as simple functions of buyer and seller concentrations, industry occupacity and ‘cohesion’ between sellers. This work provides a first practical test of this new approach. It is shown that the model fits the observed data best if the ‘cohesion’ declines as occupacity declines. It is suggested that the approach would be useful in understanding the behaviour of other ‘near-commodity’, capital-intensive businesses, and in helping to distinguish between those businesses where margins are likely to remain relatively stable and those which might face drastically declining margins if the industry occupacity declines or new entrants change the balance between sellers and buyers.     

Seller curation in platforms

This article explores why market platforms do not expel low-quality sellers when screening costs are minimal. I model a platform market with consumer search. The presence of low-quality sellers reduces search intensity, softening competition between sellers and increasing the equilibrium market price. The platform admits some low-quality sellers if competition between sellers is intense. Recommending a high-quality seller and this form of search obfuscation are complementary strategies. The low-quality sellers enable the recommended seller to attract many consumers at a high price and the effect of the recommendation is strengthened as low-quality sellers become more adept at imitating high-quality sellers.     

To invest or screen efficiently: a potential conflict in relationships governed by incomplete contracts

We consider a dynamic trade relationship where quality is not contractible and potential sellers retain quality-relevant private information. We show that the presence of an investment technology to improve the incumbent seller’s innate quality may impair the efficiency of the screening process. If the conflict is effective, the buyer has to induce an inefficient screening process or reduce the productivity of the investment technology. This conflict suggests that the hold-up problem may be more severe than predicted by models of incomplete contracts that assume complete information.     

Cheap Exclusion in Markets with Multiple Complements

We extend the theory of exclusive dealing in first-mover environments to settings where the incumbent seller’s product is used with multiple complements in a distribution chain and the incumbent can sign exclusive dealing contracts with more than one of them. The model is motivated by the market for biosimilar pharmaceuticals, where incumbent sellers that face a threat of entry can sign exclusionary contracts with both providers and insurance carriers prior to entry. We show that when the incumbent’s complementors are vertically related, it can be profitable for the incumbent to sign exclusive contracts with indirect buyers, who operate downstream from the direct buyers of the product. Under linear pricing, such exclusion is profitable if the pass-through rate is sufficiently low, and under nonlinear pricing and symmetric Nash bargaining, it is profitable for all pass-through rates. Complementors face a more severe coordination problem than independent buyers that can make anticompetitive exclusion more likely and especially cheap.     

Collusion through Coordination of Announcements

A theory is developed to explain how sellers can effectively collude by coordinating on list prices (or surcharges), while leaving sellers to set their final prices. List prices are interpreted to be cheap talk announcements about cost information unknown to buyers. Buyers use those announcements to decide whom to invite to their procurement auction and the reserve price to set. By coordinating on a high list price to signal high cost, sellers produce supracompetitive prices by inducing buyers to be less aggressive, as reflected in a higher reserve price. We show that collusion can raise social welfare.     

Housing Market Conditions, Listing Choice and MLS Market Share

In some housing markets, a seller may hire a broker to multiple list or exclusively list a property for sale or may bypass the brokerage industry and list the property privately as a "sale by owner." This article introduces a new model that illustrates the factors which will impact on the broker's and seller's preferred type of listing. An implication of the model is that if the choice is available, sellers and real estate brokers will employ a multiple listing service more often during slower market periods where the volume of sales is low and properties are more difficult to sell. An empirical analysis of Vancouver data yields results consistent with these arguments.     

The Gains from Corporate Selloffs: The Case of Real Estate Assets

Recent financial economics literature has hypothesized that variations in market structure influence the distribution of gains from corporate restructuring between buyers and sellers. We test this hypothesis using data on restructuring involving real estate assets by isolating the effects depending on multiple versus single bidders, acquisition frequency and transaction type. While we find gains for both buyers and sellers, the buyers gain only when they make few purchases. Those firms pursuing an acquisition strategy show no gains around the specific acquisition announcements. Additionally, both buyers and sellers are more likely to have a positive reaction to the announcement when the transaction is property rather than a division or subsidiary.     

Risk aversion and auction design: Theoretical and empirical evidence

Auctions are inherently risky: bidders face uncertainty about their prospects of winning and payments, while sellers are unsure about revenue and chances of a successful sale. Auction rules influence the allocation of risk among agents and the behavior of risk-averse bidders, leading to a breakdown of payoff and revenue equivalence and a heightened significance of auction design decisions by sellers. In this paper, we review the literature on risk aversion in auctions, with an emphasis on what can be learned about auction design from theoretical modeling and empirical studies. We survey theoretical results relating to the behavior of risk-averse agents in auctions, the comparison of standard auction formats in the presence of risk aversion and implications for auction design. We discuss standard and more recent approaches to identifying risk preferences in empirical studies and evidence for the significance of risk aversion in auction applications. Finally, we identify areas where existing evidence is relatively scant and ask what questions empirical research might ask given the theory and where further theoretical research may be beneficial given existing empirical results.     

How much are sellers willing to pay for the features offered by their e-commerce platform?

The success of an e-commerce platform is significantly dependent on the number of sellers and their quality. Thus, it is important to understand the factors that influence a seller's platform choice. This paper investigates features of an e-commerce platform on which sellers place high value when choosing a platform to sell their products, using a conjoint analysis. The data was collected by online survey from 1,796 sellers who are using Naver Smart Store (https://sell.smartstore.naver.com), which is one of the largest e-commerce platform in South Korea. After analyzing the willingness to pay for each combination of functions by separating six functions of Naver Smart Store, it was estimated that the MWTP ranged 3.05 to 4.48 for the main process related functions and 2.61–5.3 for the sub process related functions. MWTP can be considered as a benefits for the sellers since Naver does not require monetary commissions from sellers. This paper also shows that the higher technical understanding of the functions provides the more value to platform to sellers.     

Market Mechanism Choice and Real Estate Disposition: Search Versus Auction

We propose a model of mechanism choice in the disposition of real estate assets where we consider two alternatives: a search market and an auction. Within the search framework, we derive an equilibrium whereby buyers incur search costs and sellers incur holding costs for the period during which the property is not sold. In the auction alternative, the seller joins an existing pool of sellers in undertaking a multiple–object auction and pays a commission upon sale. Buyers and sellers freely choose their mechanisms, which in equilibrium are optimal given each group's conjectures about the mechanism choice of their counterpart. In equilibrium, an agent cannot benefit from deviating from his choice and each agent's beliefs are consistent with the equilibrium outcome. It is shown that (a) buyers with high search costs will choose auctions because the auction payoff imposes an upper bound on buyers' gains from search, and (b) prices at auctions will be higher. Using vacant lot sales data and a method–of–moment estimator which accounts for the presence of an endogenous discrete mechanism choice variable, we estimated a hedonic regression to detect the price effect. It was determined that, on average, lots sold for $1.44 per square foot more in auctions than in the search market, as predicted by our model.     

A flexible approach to determining financial terms of sale

With high inflation and interest rates the financial or credit terms of a sale are an increasingly important source of foods for buyers and an expensive cost for sellers. This article proposes some guidelines for setting terms of sale policies which may benefit both buyers and sellers. A method for determining the best terms alternative from the buyers perspective is also described.     

The Disciplining Effect of Concern for Referrals: Evidence from Real Estate Agents

Real estate agents rely on clients for referrals to generate future business; this article examines whether concern for referrals disciplines agents. We compare results for sellers who move to another area (and are less likely to provide referrals) with results for sellers who remain in the area (and are more likely to provide referrals). We find that moving‐away sellers’ houses have a higher sale rate, sell faster and sell for less (even after controlling for moving‐away sellers’ greater impatience). We also provide evidence that the disciplining effect of concern for referrals is stronger for agents who place a greater value on reputation. Finally, among sellers who are better at evaluating and monitoring agents, we see less of the high sell rate, low sale‐price effect.     

Relationship quality as a resource to build industrial brand equity when products are uncertain and future-based

This article extends our understanding of industrial branding and the influence of buyer–seller relationships by examining key constructs within an industrial context where products are uncertain and future-based. SEM results elicited from 249 buyer surveys empirically validate satisfaction, trust and commitment as dimensions of relationship quality, and show that buyer–seller relationship quality facilitates direct and indirect seller brand equity accruals. Findings reveal that while focusing on sellers' corporate and product brands is good advice for building buyer–seller relationships, seller resource allocations to these areas should vary depending upon the selected target market segment(s). Findings support that sellers should place more focus on developing quality relationships with buyers than they should in focusing on the non-relational attributes of their corporate brands; however, if sellers choose to bypass building high quality customer relationships, they should instead funnel resources into their product brand offerings. Findings demonstrate that buyers credit their own skills and acumen when evaluating products with which they are confident, and ascribe increased value to the involvement of the seller as their attitude and certainty decrease. These findings provide strategic guidance to the sellers of uncertain and future-based industrial products.
