‘Subjective’ price search and price competition

In this paper we study price rivalry between two firms facing a population of imperfectly informed buyers. The two sellers are geographically dispersed and consumers search for the lowest price. The competitive process either suffers from cyclical instability or stabilises at that price at which no buyer searches.     

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.     

Group identity in markets

We present a laboratory experiment that measures the effects of group identity—one's perceived membership in social groups—on market transactions in an oligopoly market with a few sellers and buyers. We artificially induce group identity using art preferences and college majors in different treatments, respectively. Subjects are randomly assigned into the roles of buyers and sellers and interact repeatedly. We find that the presence of groups influences both the selection of trading partners and the determination of prices. All else equal, sellers are more likely to make offers to ingroup buyers, and the buyers are more likely to accept offers from ingroup sellers. There are considerable intergroup price differentials with the outgroup sellers charging a lower price than the ingroup sellers.     

List Prices,Sale Prices and Marketing Time: An Application to U.S. Housing Markets

Many goods are marketed after first stating a list price, with the expectation that the eventual sales price will differ. In this article, we first present a simple model of search behavior that includes the seller setting a list price. Holding constant the mean of the buyers’ distribution of potential offers for a good, we assume that the greater the list price, the slower the arrival rate of offers but the greater is the maximal offer. This trade‐off determines the optimal list price, which is set simultaneously with the seller's reservation price. Comparative statics are derived through a set of numerical sensitivity tests, where we show that the greater the variance of the distribution of buyers’ potential offers, the greater is the ratio of the list price to expected sales price. Thus, sellers of atypical goods will tend to set a relatively high list price compared with standard goods. We test this hypothesis using data from the Columbus, Ohio, housing market and find substantial support. We also find empirical support for another hypothesis of the model: atypical dwellings take longer to sell.     

Search algorithm,repetitive information,and sales on online platforms

A prominent feature of online sales is that buyers rely on the search tools offered by platforms to process information when searching for products. We develop a model that captures how the search algorithm affects buyers’ search processes, which further influences market equilibrium and welfare. If a platform adopts a highly unequal search algorithm, buyers are likely to obtain repetitive information about a small group of sellers, which causes buyers to consider fewer options and suppresses competition. By using data from food delivery platforms, we provide empirical evidence that markets with less equal distributions of store rankings in search results have higher average prices and more concentrated sales. We suggest that regulators should restrict search algorithms from showing repetitive information.     

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.     

Platform Price Parity Clauses and Consumer Obfuscation*

Several antitrust authorities have investigated platform price parity clauses around the world. I analyze the impact of these clauses when platforms design a search environment for sellers and buyers to interact. In a model where platforms choose the unit search cost faced by consumers, I show when platforms can profitably obfuscate consumers through high search costs. Then, I show that price parity clauses, when exogenously given, can increase or reduce obfuscation, prices, and consumer surplus. Finally, when price parity clauses are endogenous, they are only observed in equilibrium if they hurt consumers.     

Contigent Price Contracts and the Efficiency of Housing Markets

Frequently, the response of housing markets to a large negative demand shock is a period during which the liquidity of housing declines, but the price at which transactions take place changes little. In this paper we show that a decline in liquidity can result from the inabilities of sellers and buyers to insure against post-shock price uncertainty. We conclude, that the introduction of a risk-sharing contingent price contract may increase the post-shock liquidity of housing by providing insurance against post-shock price uncertainty. Finally, we show that a mutually agreeable contingent price contract will always exist, even when sellers are excessively optimistic.     

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.     

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.     

USING RESERVE PRICES TO DETER COLLUSION IN PROCUREMENT COMPETITION*

To enhance our understanding of collusion in procurement settings, this paper quantitatively evaluates how the buyer's choice of a reserve price influences the sustainability of two previously devised collusive schemes. If the buyer does not select its reserve price strategically, then collusion may be sustainable for a wide range of plausible discount factors. However, even mildly sophisticated reserve price selection can dramatically shrink the set of discount factors for which collusion is sustainable. These findings support existing arguments that buyers are vulnerable to collusion, but they also suggest that buyers possess tools that may profitably induce sellers to act competitively.     

Platform Investment and price parity clauses*

Platforms use price parity clauses to prevent sellers setting lower prices when selling through other channels. They claim these restraints are needed so platforms have incentives to invest in providing search services—without them, consumers would search on the platform but then switch to buy in a cheaper channel. In a model incorporating these effects, we find that wide price parity clauses lead to excessive platform investment while narrow (or no) price parity clauses lead to insufficient platform investment. Taking these investment effects into account, wide price parity clauses lower consumer surplus but have ambiguous effects on total welfare.     

FHA Mortgage Discount Points, House Prices and Consumer Behavior

The allocation of FHA discount points between buyers and sellers has recently been the subject of empirical investigation. The research reported here examines this relationship in more detail. Regression equations were estimated for separate price categories of housing using dummy variables for the number of discount points being charged. Separate equations were also estimated for periods when points were rising and when they were falling. The results essentially are that sellers attempt to shift all of the discount points to buyers and frequently are successful. However, in certain situations the points are shared between buyers and seller.     

House Price Changes and Idiosyncratic Risk: The Impact of Property Characteristics

Although the average change in house prices is related to changes in fundamentals or perhaps market-wide bubbles, not all houses in a market appreciate at the same rate. The primary focus of our study is to investigate the reasons for these variations in price changes among houses within a market. We draw on three theories for guidance, one related to the optimal search strategy for sellers of atypical dwellings, another focusing on the bargaining process between a seller and potential buyers and the third relying on the concept of land leverage. We hypothesize that houses will appreciate at different rates depending on the characteristics of the property and the change in the strength of the housing market. These hypotheses are supported using data from three New Zealand housing markets.     

The Gender Gap in Real Estate Sales: Negotiation Skill or Agent Selection?

This study examines differences in net selling price for residential real estate across male and female agents. A sample of 2,020 home sales transactions from Fulton County, Georgia, are analyzed in a two‐stage least squares, geospatial autoregressive corrected, semi‐log hedonic model to test for gender and gender selection effects. Although agent gender seems to play a role in naïve models, its role becomes inconclusive as variables controlling for possible price and time on market expectations of the buyers and sellers are introduced to the models. Clear differences in real estate sales prices, time on market and agent incomes across genders are unlikely due to differences in negotiation performance between genders or the mix of genders in a two‐agent negotiation. The evidence suggests an interesting alternative to agent performance: that buyers and sellers with different reservation price and time on market expectations, such as those selling foreclosure homes, tend to select agents along gender lines.     

Quality infomediation in search markets

We examine the effects of informational intermediation by a third party ‘infomediary’ in a search model with heterogeneous seller qualities and asymmetric information. The infomediary earns revenue by selling a list of accredited sellers (a ‘guidebook’) to buyers and selling accreditations to sellers. We show that such information always improves welfare but can hurt informed buyers (as well as the uninformed) if it is not sufficiently informative about seller qualities. The model also provides a number of insights concerning the private and social incentives to create information, and the determinants and nature of demand for infomediation services by buyers and sellers.     

Competing through information provision

This paper studies the symmetric equilibria of a two-buyer, two-seller model of directed search in which sellers commit to information provision. More informed buyers have better differentiated private valuations and extract higher rents from trade. When sellers cannot commit to sale mechanisms, information provision is higher under competition than under monopoly. In contrast, when sellers commit to both information provision and sale mechanisms, I identify simple conditions under which sellers post auctions and provide full information in every equilibrium, ensuring that all equilibrium outcomes are constrained efficient. Sellers capture the efficiency gains from increased information and compete only over non-distortionary rents offered to buyers.     

On the incidence of commissions in auction markets

We analyze the welfare consequences of an increase in the commissions charged by intermediaries in auction markets. Commissions are similar to taxes imposed on buyers and sellers, and standard economics suggests that both sellers and buyers are made worse off by the tax. However, we show that when the buyers' participation constraint binds and when sellers set optimal reservation prices, the level of commissions correlates to participation and reservation prices in such a way that participating buyers strictly gain from higher commissions.     

Building trust in US-Japanese business relationships: Mediating role of cultural sensitivity

While evidence suggests trust plays a fundamental role in maintaining successful buyer-seller relationships in Japan, little is known conceptually as to how foreign sellers can best develop trust in the minds of their Japanese customers. In this research, we develop and test a multi-component model of US seller actions that manifest key trust-building processes (intentionality- and capability-processes) which sellers find effective in building trust with their Japanese buyers. In this unique cultural context, theory suggests trust develops when sellers demonstrate benevolent intentions toward the buyer and exhibit a strong capability to fulfill business promises. An analysis of 181 US sellers in Japan demonstrates that a combination of trust-building efforts is recognized as being critical in seller attempts to develop and sustain trust on the part of their Japanese customers. Importantly, cultural sensitivity mediates the impact of intentionality-based practices on buyer trust, while capability-based activities directly influence trust.     

COSTLY BUYER SEARCH IN LABORATORY MARKETS WITH SELLER ADVERTISING*

In this experiment, sellers simultaneously choose prices and advertising strategies. Buyers either purchase at an advertised price or search sequentially for other prices. In the unique symmetric equilibrium, sellers charge a high unadvertised price or advertise a price chosen from a lower interval. Increases in search or advertising costs raise equilibrium prices and affect equilibrium advertising intensity. Empirical results are consistent with most comparative static predictions. Sellers, however, price much lower and advertise more intensely than predicted. Consequently, market outcomes more closely resemble a perfect information, Bertrand‐like equilibrium than the imperfect information, mixed strategy equilibrium with significant seller market power.
