Antitrust and Sales-Below-Cost Laws: The Case of Retail Gasoline

Numerous states have sales-below-cost (SBC) laws, often directed at specific products such as gasoline. Potential violations of state SBC laws occur when prices are less than the seller's cost of doing business, or some proxy thereof. The most commonly stated purpose of these laws is to protect small independent firms from predation by larger firms. This study offers empirical evidence on the impact of SBC laws on the retail gasoline market. The result indicate that SBC laws directed specifically at the retail gasoline market have resulted in higher retail margins.     

Antitrust in High-Tech Industries

Recent economic growth has been led by high-technology industries (See Jorgenson, Ho & Stiroh (2005) for a summary of the research on the recent acceleration of productivity growth). Many firms in these industries have achieved a dominant market position, thereby attracting the attention of competition authorities, often resulting in major monopolization cases. Unfortunately, this attention has not resulted in improved market outcomes. In this paper, we evaluate the effect of Section 2 Sherman Act cases brought against IBM, AT&T, and Microsoft. We conclude that these cases had limited effect on consumer welfare because they did not stimulate entry or innovation. In these industries, competition authorities cannot expect to promote simply an expansion of output and lower commodity prices; rather they should focus their remedies on promoting innovation—new products that replace or compete with the dominant firm’s products.     

Buyer power and exclusion in vertically related markets

Suppliers and consumer organizations have become increasingly concerned by the build-up of buyer power of retailers in many markets. A major concern is that strong retailers will abuse their power to exclude products and rival retailers from the market to be able to increase prices to consumers. As a consequence, remedies to limit buyer power are discussed and implemented in many countries. In this paper we compare the incentives for exclusion, and the effect on consumers prices, under both buyer and seller power. We study a model with a dominant upstream manufacturer and a competitive fringe of producers offering their products to two differentiated downstream retailers. We compare the equilibrium outcome of this model when i) the dominant supplier holds all the bargaining power, and (ii) the retailers have all the bargaining power. We show that full or partial exclusion of either the competitive product or downstream retailers occurs when inter and intrabrand competition are strong. This is true both under seller and buyer power. However, in contrast to the received literature, we find that buyer power weakly enhances welfare compared to seller power because buyer power will lead to both more product variety (less exclusion) and lower retail prices.     

The role of ambiguity tolerance in consumer perception of remanufactured products

This study examines ambiguity tolerance, perceived quality, and willingness to pay for remanufactured products. We found evidence to support a direct relationship between a consumer's tolerance for ambiguity and their willingness to pay for remanufactured products. There was also support for an indirect relationship between ambiguity tolerance and willingness to pay that is mediated through perceived quality. Extant literature often lacks an empirical justification regarding costing and quality assumptions for remanufactured products. This research provides such justification while also offering an explanation as to why consumers view remanufactured products as being of lower quality and are less willing to pay for them. Those employed in the remanufacturing industry are advised to reduce the level of ambiguity associated with their remanufacturing processes in order to command higher prices for their products in the marketplace.     

Reprint of: Crop prices and the individual decision to migrate

This paper investigates the effect of commodity prices, in particular rice and coffee, on the decision of migrating at the individual level. As most coffee production is sold by households for exports, we would expect that coffee price shocks would have a direct effect on the probability to migrate. On the other hand, we would anticipate that fluctuations in rice prices have little or no effect on migration decisions, given that rice is mainly produced for household consumption. We test these hypotheses drawing evidence from migration in Viet Nam. We show that the lower the price of coffee, the higher the likelihood of migrating. This evidence seems to suggest that migration acts as a shock-coping strategy. We find that rice prices have no effect on the probability of migrating. We further explore the extent of migrants’ self-selection and show that lower coffee prices increase the migration probability of individuals with lower education.

LISTING PRICES AS SIGNALS OF QUALITY IN MARKETS WITH NEGOTIATION*

We analyze markets where a buyer may pay the listing price or negotiate. We show that listing prices can signal quality to attract the right type of buyers. Prices are lower without quality uncertainty or without some of the lower qualities. In equilibrium, higher qualities/prices induce more bargaining, and thus more expensive goods are sold more often through bargaining.     

Price dispersion and seller heterogeneity in retail food markets

Price dispersion, i.e. a homogeneous product being sold at different prices by different sellers, is among the most replicated findings in empirical economics. The paper assesses the extent and determinants of spatial price dispersion for 14 perfectly homogeneous food products in more than 400 retailers in a market characterized by the persistence of a large number of relatively small traditional food stores, alongside large supermarkets. The extent of observed price dispersion is quite high. When prices in an urban area (where the spatial concentration of sellers is higher) are compared with those in smaller towns and rural areas, differences in search costs and the potentially higher degree of competition do not yield lower prices. Other counteracting factors, including differences in seller costs and consumer incomes, make prices, on average, higher in the urban area for 11 of the 14 products considered. For many, but not all, the products supermarkets proved to be less expensive than traditional retailers, although average savings from food shopping at supermarkets were extremely low. Finally, the results of the study provide evidence that retailers have different pricing strategies and these differences also emerge for supermarkets belonging to the same chain. The results presented in the paper suggest that a variety of factors play a role in explaining price dispersion. In addition to differences in seller costs, the contemporaneous heterogeneity of retailers (in terms of services provided) and consumers (in terms of search costs and preferences) makes the emergence of monopolistic competition possible as well as allowing small traditional food retailers to remain in business.     

Resource-constrained product development: Implications for green marketing and green supply chains

While academic debates and practical approaches to green marketing have matured over the past few decades, one central conundrum that has remained unresolved has been the trade-off between the higher prices of green products and the objectives of environmental sustainability. In general, it has been observed that green products are priced at a premium to account for their environmentally friendly consumption and use. We argue that resource-constrained product development approaches (alternatively labeled jugaad) that are observed in emerging countries such as China and India have the potential to change the traditional models of green product development. In addition to the competitive advantage that resource-constrained product development approaches provide, we suggest that these practices have sustainability and supply chain benefits. We show that the innovation process relies primarily on frugal engineering that reduces material use (thereby reducing burden on supply chain) and meets green marketing objectives at much lower, and therefore, more affordable prices. We draw out several implications for theory and practice.     

The effect of online shopping channels on brand choice,product exploration and price elasticities

This paper analyzes the effect of an online shopping channel on private label purchases, product exploration and price elasticities. Variation in the timing that an online shopping service was introduced is utilized as a source of exogenous variation in the decision to shop online. Event study estimates indicate a 0.3 to 1.0 (1.0 to 2.0) percent increase (reduction) in the proportion of private label (new) products purchased after the introduction of the online shopping service. Price elasticities are then estimated utilizing an Exact Affine Stone Index (EASI) demand model. Comparisons of in-store and multichannel price elasticities indicate that households are, on average, less price sensitive when shopping across both the in-store and online channels. Own-price (cross-price) elasticities are 1.07 (5.56) times larger in-store than they are in a multichannel setting. These findings suggest that retailers manipulate the online search platform and(or) the provision of substitutes to favor private label products, which have a higher margin. Additionally, these results suggest that retailers may find it profit maximizing to raise prices as consumer baskets become more sticky in the multichannel purchasing regime.     

Timing Product Replacements under Uncertainty—The Importance of Material–Price Fluctuations for the Success of Products That Are Based on New Materials

Being first to market with new products is one of the most enduring pieces of strategic advice handed to managers. This view also emphasizes the importance of launching new products that are based on new materials as soon as possible. However, when the input costs of products that embody new materials are uncertain because of volatile material prices, the advantage of being an early mover comes along with the risk of paying unexpectedly high material prices. Real‐option theory suggests delaying material substitution under uncertainty even if the new material enables superior product performance. Firms who have created the flexibility to switch between alternative inputs can benefit from responding to opportunities or threats that arise from changes in the environment. The current study formalizes this logic in a switching‐option model and tests it on a sample of material substitution projects from the manufacturing sector. Our findings shed light on how input‐cost fluctuations influence the timing–performance relationship and bring into question the common advice to launch new products as soon as possible. Instead, our results suggest that firms who align the timing of market launch to trends and fluctuations of material prices improve their competitive positions. These insights suggest novel ways for new product development (NPD) managers how to successfully use external information at the back‐end of the NPD process and how to compete in an era defined by volatile material prices and technological change.     

Model Exit in a Vertically Differentiated Market: Interfirm Competition versus Intrafirm Cannibalization in the Computer Hard Disk Drive Industry

What characteristics of a product’s local market make its withdrawal more likely? This study investigates the importance of intrafirm “cannibalization” of a product’s demand by products manufactured by the same firm versus interfirm competition from others’ products. While both forces impact product withdrawal, cannibalization has a more robust and significant effect. Hedonic price regressions also reveal higher discounting of older models’ quality-adjusted prices, strengthening the argument for caution when treating list prices as proxies for transaction prices.     

Food aid: pitfalls and potential

This article poses the question of whether it is possible to use food aid to meet short-run needs while supporting and not undermining the achievement of long-term goals of self-reliance at the household and national levels. Often either some degree of self-reliance is sacrificed or people will suffer malnutrition. Food aid may be used to generate employment for low income families (food-for-work schemes), to reduce food prices during shortages by increasing the supply, and it can be delivered to target groups as a direct entitlement. What happens to food after delivery is important: often it goes to family members not targeted. Other factors (e.g. measles) affect nutritional status. Food aid must often continue for long periods to avoid nutritional regression. The stage in distribution at which food is used is important; e.g. a measles epidemic might affect the consumption but not the supply of food, or poor targeting might benefit families who do not need it. Complementary actions may improve conditions; for example, if food is sold, increasing income improves the situation. A problem with provision of food is depression of local prices, reducing incentives to produce food locally. Most food aid does not increase demand, and in fact if the effect is to change tastes away from local products demand may be reduced. The effect on demand depends on the type of aid scheme, the timing and duration, and the locality of the project. Most objectives are better achieved by the use of cash aid, which promotes rather than weakens local food producers' incentives, reduces transport and storage, redistributes food, does not affect taste, and adds income by contributing to local decentralized transport. Food aid is a good temporary intervention, but cash aid should be used in the long term.     

Prices and Departures in European Domestic Aviation Markets

Using data on 172 domestic city-pair markets in eight European countries, weinvestigate the effect of the market structure on airlines choices of departuresand prices. We find that flag carriers have a higher number of departures thanother airlines and that it is more likely that flag carriers are monopolists. At thesame time flag carriers do not have a higher ticket price than other airlines. Theinfluence of market power, measured with the Herfindahl index, does not havea significant effect on ticket prices, but a significant effect on the number ofdepartures: decreased market concentration and an increased number of airlinesresults in increased aggregate frequencies. Comparing the predicted ticket prices,at sample mean, between monopoly and non-monopoly routes we can reject thehypothesis of differences in equilibrium price. However, the predicted aggregatenumber of departures, calculated at sample mean, is significantly higher at non-monopoly routes compared with monopoly routes.     

Innovations,Prices and Employment: A Theoretical Model and an Empirical Application for West German Manufacturing Firms

In this paper a theoretical model of the impact of product and process innovations on output, capacity utilization, employment and prices is developed. The model is estimated with a unique set of micro-data from West German manufacturing firms. The empirical results reveal that innovative firms are more successful. They show a higher utilization and more output and employment growth than non-innovative firms. Innovations also change market behaviour. In sectors with a large share of product innovators, firms more often change employment and less often change prices, i.e. product innovations reduce price competition.     

Local impacts of a global crisis: Food price transmission,consumer welfare and poverty in Ghana

This paper takes a local perspective on global food price shocks by analyzing food price transmission between regional markets in Ghana. It also assesses the impacts of food price increases on various household groups. Taking the 2007–2008 global food crisis as an example, we show that prices for domestic grain products are highly correlated with world market prices. This is true both for products for which Ghana is highly import-dependent (e.g., rice) and the products for which Ghana is self-sufficient (e.g., maize). The econometric results also show that price transmission is high between regional producer markets and markets located in the country’s largest cities, and the distance between producer and consumer markets and the size of consumer markets matter in explaining the price transmission. The welfare analysis for households as consumers shows that the effect of world food prices appears relatively modest for the country as a whole due to relatively diverse consumption patterns within country. However, the national average hides important regional differences, both between regions and within different income groups. We find that the poorest of the poor—particularly those living in the urban areas—are hardest hit by high food prices. The negative effect of the food crisis is particularly strong in northern Ghana. The main explanations for this regional variation in the price effect is the different consumption patterns and much lower per capita income levels in the North of Ghana compared to other regions in the country.     

Multiproduct two part tariffs

Two part pricing by a multiproduct monopoly and a differentiated oligopoly are examined and compared. Two part pricing policies are seen to depend on whether products are complements or substitutes and on whether or not the market is segmented. A principle result is that although competition tends to lower unit prices, there is no corresponding tendency for competition to reduce entry fees. The unit pricing rule is related to the Ramsey pricing rule. Oligopoly equilibrium unit prices equal marginal cost when there is one consumer type.     

The Effect of Appeals on Assessment Ratio Distributions: Some Nonparametric Approaches

A variety of nonparametric methods—locally weighted regression, nonparametric quantile regression and conditional density functions—are used to evaluate the effect of appeals on assessment uniformity. Unlike previous studies, the focus is on the full distribution of assessment ratios rather than on central moments. Data for single‐family homes in Chicago for 2006 suggest that appeals lead to a modest reduction in assessment variability, but the density of extremely high assessment ratios is higher among homes without appeals. Whereas traditional methods simply indicate that assessment ratios decline with sale price, nonparametric approaches reveal that higher prices have a more pronounced effect on the variance than on the conditional expectation of the assessment ratio distribution and that the most pronounced degree of regressivity occurs at very low sales prices.     

Curbing obfuscation: Empower consumers or regulate firms?

This paper develops a market model where consumers refrain from buying products that they are unable to understand and a firm can influence the probability of a consumer understanding its offer. In equilibrium, firms artificially increase product complexity, and firms that offer more transparent products choose on average higher prices. We study two sets of public policies. We show that consumer side policies may have the unintended consequence of encouraging obfuscation while firm side policies are always effective in curbing obfuscation. Interestingly, a consumer side policy can even harm consumers when it protects consumers so much that it greatly increases the marginal effectiveness of obfuscation. Policies on both sides can either increase or decrease social welfare depending on the marginal effectiveness and the marginal cost of obfuscation. Our main insights hold in both asymmetric and symmetric obfuscation equilibria.     

Crossownership and media concentration

This paper investigates whether media concentration permits newspaper and group owners of television stations to charge higher advertising rates than other types of owners. The prior studies that have looked at this issue have had to rely on questionable data. This study focuses on more accurate data, i.e. selling prices. It is argued that the potential for higher advertising rates could cause newspaper and group owners to pay higher prices for television stations than other types of buyers. An empirical analysis was made of sales of television stations between 1960 and 1969. The results tend to show that newspaper owners were willing to pay higher prices. A second analysis was done to determine whether the higher prices were due to market power or economies of scale. The results tend to show that the higher prices were probably due to the market power possessed by newspaper owned stations, some of which spills over to the other stations in the market.
