Demand for coffee in Sweden: The role of prices, preferences and market power

There is a widespread belief that consumer coffee prices are high relative to bean prices and that lower consumer prices would lead to substantial increases in bean exports from Third-World countries. This issue is evaluated by analysing how retail prices, preferences and market power influence coffee demand in Sweden. A demand function is estimated for the period 1968–2002 and used, together with information on import prices of coffee beans, to simulate an oligopoly model. This approach gives estimates of the maximum average degree of market power and shows how coffee demand would react to reductions in marginal cost to its minimum level. The maximum level of market power is found to be low, but it generates large spreads between consumer and bean prices because the price elasticity has low absolute values. Moreover, the impact of a price decrease would be small because long-run coffee demand is dominated by changes in the population structure in combination with different preferences across age groups. Hence, a change to perfect competition would only have a negligible effect on bean imports.     

Are prices ‘sticky’ online? Market structure effects and asymmetric responses to cost shocks in online mortgage markets

We analyze daily mortgage rates posted by online lenders at the price comparison site, Microsurf. While cost shocks occurred almost daily in our sample, quoted mortgage rates are surprisingly rigid: Only 16% of the posted rates represent changes. However, firms that adjusted rates in response to cost shocks did so quite rapidly; about 98% of a cost shock was passed through within 2 days of the cost shock. Duration analysis reveals that the observed rigidity in rates systematically depends on market structure: Online mortgage rates are 30% to 40% more durable in concentrated markets than in markets where there are many competitors. We also find that rates posted online tend to exhibit downward stickiness; rate adjustments in response to cost increases are about twice the corresponding adjustments for cost decreases.     

Segmentation, advertising and prices

This paper explores the implications of market segmentation on firm competitiveness. In contrast to earlier work, here market segmentation is minimal in the sense that it is based on consumer attributes that are completely unrelated to tastes. We show that when the market is comprised by two consumer segments and when there is sufficient variation in the per-consumer costs firms need to incur to access the different consumer populations, then firms obtain positive profits in symmetric equilibrium. Otherwise, the equilibrium is characterized by zero profits. As a result, a minimal form of market segmentation combined with advertising cost asymmetries across consumer segments give firms an opportunity to generate positive rents in an otherwise Bertrand-like environment.     

Why are African commodity exchanges languishing? A case study of the Zambian Agricultural Commodity Exchange

Food price volatility and high transactions costs remain major problems in African food markets. These persistent problems provide a strong theoretical justification for the development of commodity exchanges. However, the majority of African commodity exchanges remain underdeveloped. Through a case study of the Zambian Agricultural Commodity Exchange (ZAMACE), this article explores why agricultural commodity exchanges in the region have thus far failed to develop into sustainable trading platforms and identifies the most important changes needed to enhance their performance.     

Is Airline Price Dispersion the Result of Careful Planning or Competitive Forces?

We develop a model of price dispersion to distinguish the impact of price discrimination from that of peak load pricing schemes or atypical competition resulting from the financial difficulties of the early 1990s. By utilizing three alternative measures of dispersion and appealing to economic theory for our specification, we find robust results suggesting an estrangement between price dispersion and price discrimination. While some discrimination continues to persist at monopolized endpoints, most dispersion is associated with fare wars and peak load pricing schemes.     

The impact of shopbot use on prices and price dispersion: Evidence from online book retailing

Internet price search tools, notably shopbots, have reduced consumers' search costs for price and product characteristics. While a variety of analytic models predict that increased consumer search will lower price levels among competing retailers, there is no consensus in the literature as to how price dispersion will change with increased consumer search. Moreover, there are no papers that have empirically tested these predictions using direct observation of variation in shopbot use over time.This paper examines the impact of changes in shopbot use over time on pricing behavior in the Internet book market. We do this by combining price and clickstream data collected from August 1999 to July 2001 — a period of rapid expansion in shopbot use. We find that a 1% increase in shopbot use is correlated with a $0.41 decrease in price levels and a 1.1% decrease in price dispersion.     

Variation in retail costs for fresh vegetables and salty snacks across communities in the United States

Households living in different communities pay different amounts of money for food. Food costs depend on whether a household lives in an urban community or in a locality with a high incidence of poverty, among other factors. This study focuses on spatial variation across the United States in the retail costs for fresh vegetables and salty snacks. Findings reveal that the major economic and demographic characteristics of a household’s community affect its costs for these two types of foods differently. However, households are likely to pay more money for salty snacks in communities where fresh vegetables also cost more.     

New technology introduction in a marginal coffee area of Colombia

Income stagnation in the downward cycle of primary product prices is a problem for small farmers in developing countries. The recent abrupt price decline in coffee poses a large adjustment problem in marginal production areas. One method of farm income stabilization for marginal export crop production areas is diversification into food crops with improved technology. The potential for a cushioning of this farm income decline via the introduction of improved food crop technology was examined. A substantial moderating effect was obtained even without uprooting the improved coffee technology. Moreover, an analysis of the constraints to the earlier introduction of the Caturra coffee variety helped identify some of the components of farmer decision making relevant to adoption of new technology.     

Successful branding of a commodity product: The case of RAEX LASER steel

In today's competitive business environment, industrial marketers must work harder than ever before to achieve some degree of differentiation for their products to avoid being viewed as a commodity. Many firms have sought to achieve this differentiation by branding their products. Branding, however, is more than simply putting the company's name on a product and broadcasting that name to its target audiences. For industrial products, branding is a multidimensional construct that includes not only how the customers view the physical product, but also the logistics, customer support, and corporate image and policy that accompany this product. This paper discusses how the Finnish steel company Rautaruukki was able to successfully incorporate these four components into their RAEX LASER steel, a brand specifically targeted for job shops who do laser cutting. The paper concludes with managerial implications and suggestions for how industrial marketers might implement their own branding strategy.

On commodity taxation in vertically differentiated markets

We examine the impact of commodity taxation on vertically differentiated product markets when entry is allowed. We show that an ad valorem tax may have a dramatic effect on market structure by inducing the entry of a large number of firms in what was previously a natural monopoly. The producers of high quality products reduce market share after an increase in their unit production cost, leaving more room for lower quality products. While within a given market structure aggregate quality decreases monotonically with the tax rate, quality jumps upwards at tax rates that cause a change in market structure.     

Generic Advertising of Intermediate Goods: Theory and Evidence on Free Riding

We develop a model of generic advertising in the context of vertically dependent markets wherein producers of an intermediate good financially support, through voluntary contributions, a generic advertising campaign aimed at consumers of a final product. The Nash equilibrium is characterized by free riding on the part of upstream firms because of the nature of generic advertising, leading to its underprovision with respect to joint, industry-wide profit maximization. We test the model in the U.S. fluid milk industry focusing on the effects of generic advertising on the intermediate demand for milk, since dairy farmers support the generic advertising. Taking this approach, we find that generic advertising had a positive influence on farm-level demand for milk, but did not achieve joint profit maximization.     

Regional relationships between inherent coffee quality and growing environment for denomination of origin labels in Nariño and Cauca,Colombia

International markets are increasingly signaling demand for quality-differentiated coffee, which the Colombian Coffee Growers Federation (FNC) proposed to exploit to identify those regional coffees that would fulfill the requirements to be classified as denomination of origin. The objective of this study was to develop and implement a sound, robust and repeatable approach with and for the FNC to identify regional causal relationships between coffee quality and environmental characteristics as bases for labels of denomination of origin. Environmental differences between coffee-growing areas in the departments of Cauca and Nariño were statistically significant for several characteristics, including the number of dry months, annual precipitation and diurnal temperature range. The dominant varieties (Caturra and Colombia) did not show major differences in quality attributes, and were pooled for the analyses with the environmental data. There are significant differences in biochemical and sensorial product characteristics between the two departments. The spatial patterns in product characteristics exhibit a non-random, regionally-changing structure that is related to those in the environmental data. The generated results provided ample evidence to support the application for regionally-based denominations of origin. Recommendations were derived to help mainstreaming the developed approach and thereby facilitate policy decisions for its use in other geographies and with other crops. Furthermore, the importance of systematic interdisciplinary institutional collaboration for large-scale denomination of origin projects was corroborated for food policy dialogue and decision making. It seems plausible that producers of high-quality products within other commodities are likely to follow the FNC in seeking denomination of origin for their goods. The presented approach is crucial to facilitate policy.
