Private labels, price rivalry, and public policy

The article examines (i) why low-quality private labels are introduced in some product categories and not in others, (ii) how the existence of a low-quality private label affects the pricing of a competing national brand, and (iii) how consumers’ surplus and welfare are affected by private labels. We find that the potential for private label introduction may—in return for national brand exclusivity in that particular retail store (exclusive dealing)—lead to price concessions from the producer of the national brand. If the national brand producer decides not to offer an exclusivity contract, a private label is introduced. In this case, private label introduction may lead to higher retail prices on national brands, which can be detrimental to consumer welfare as well as total welfare. We argue that our results have important implications for the interpretation of empirical results and the public policy towards national brands     

ARE CONSUMERS MORE LOYAL TO NATIONAL BRANDS THAN TO PRIVATE LABELS?

The evolution of private labels (PLs) can be understood in terms of a strategy adopted by the retail industry with the aim of competing with national brands (NBs). In the 1990s, this strategy led to the development of ‘me too’ products, which currently represent the largest share of store brand products. Since the early 2000s, retailers have widened the range of their store brands by introducing high‐quality products. The aim of this study was to estimate consumers’ attachment to ‘me‐too’ and niche PLs respectively, as compared to NBs. We captured the degree of maturity of these PLs through their price‐elasticities, computed for three staple goods offered by three mass retail companies. It was found that price sensitivity does not differ much between the ‘me‐too’ PLs and the corresponding NBs. This result confirms that ‘me‐too’ products are now considered reliable quality brands. However, in the high quality segment, consumers remain more sensitive to the price of PLs than to that of NBs, a characteristic which may relate to their recent introduction on the market.

Time lags in the pass-through of crude oil prices: big data evidence from the German gasoline market

This article investigates the pass-through of global Brent oil notations to fuel prices across the oligopoly of retail majors in Germany. We assemble a high-frequency panel data set that encompasses millions of price observations and allows us to distinguish effects by brand. Upon establishing a cointegrating relationship between fuel and crude oil prices using daily data, we estimate an ECM and find that (1) the pass-through of oil prices critically depends on the number of time lags included in the ECM; (2) strict adherence to classical information criteria for determining lag length yields extremely long pass-through durations and (3) the estimated impulse response functions are virtually identical across brands, irrespective of the lag count, suggesting a high degree of competition among brands.     

Wine Quality and Varietal, Regional and Winery Reputations: Hedonic Prices for Australia and New Zealand

We estimate hedonic price functions for premium wine from Australia and New Zealand, differentiating implicit prices for sensory quality ratings, wine varieties and regional as well as winery brand reputations over the vintages 1992–2000. The results show regional reputations have become increasingly differentiated through time (although less so for New Zealand). In particular, cool-climate regions are becoming increasingly preferred over other regions in Australia. In each country, price premia associated with both James Halliday's and Winestate magazine's sensory quality ratings, and with Halliday's winery ratings and classic wine designations, are highly significant.     

Modelling the effects of promotion expenditures on sales of pharmaceuticals

The successful innovation of pharmaceuticals requires a substantial amount of marketing support, despite concerns about the effects of these marketing efforts. This study considers prior findings that indicate that higher marketing expenditures for a brand reduce its price elasticity of demand, which may lead to higher prices, in the context of the Dutch pharmaceutical market. The authors find that parameters are heterogeneous across brands, and that marketing effects differ across product life cycle stages. They propose a separate analysis of established and new brands. For established brands, marketing efforts neither have a positive effect on sales, nor do they affect the price elasticity. For new brands, several proposed models might capture their diffusion pattern; the diffusion-of-innovation models provide the best results. Marketing accelerates the rate of diffusion and leads to a higher baseline level of sales.     

Measurement of export prices and changes in product quality

In this paper, the economic theory of index numbers is applied to the construction of industry-level export price indices and export quality indices. These indices are used to make consistent comparisons of export prices and qualities at the same or different points in time. Evidence of quality change over time was found to be an important phenomenon in explaining the variation of unit value indices over time and across countries for some European Union trade flows. About half of the unit value differences among destination countries can be explained by quality differentials. The quality-corrected price indices are potentially useful in any empirical application in which accurate measures of export prices are needed.The authors wish to thank Bienvenido S. Cortés for valuable discussion at the Forty-Eighth International Atlantic Economic Conference, October 7–10, 1999, Montreal, Canada.     

Manufacturer's pricing strategy in a two-level supply chain with competing retailers and advertising cost dependent demand

The paper studies a two-echelon supply chain comprising one manufacturer and two competing retailers with advertising cost dependent demand. The manufacturer acts as the Stackelberg leader who specifies wholesale price for each retailer. The two retailers compete with each other in advertising and they have different sales costs. The manufacturer uses one of the following two pricing strategies: (i) setting the same wholesale price for both the retailers irrespective of the difference in their sales costs; (ii) setting different wholesale prices for the retailers depending on their sales costs. Two models are developed. In the first model, the manufacturer shares a fraction of each retailer's advertising cost while in the second model, the manufacturer does not share any retailer's advertising expenses. In both the models, we derive the retailers' and manufacturer's optimal strategies. A numerical example is given to illustrate the theoretical results developed in each model. Computational results show that it is always beneficial for the manufacturer to adopt different wholesale pricing strategy for the retailers.     

Smoke screen: Estimating the tax pass‐through to cigarette prices in Pakistan

This article estimates and compares the speed and magnitude of the tax pass‐through across major cigarette brands at different price points (budget, mainstream, and premium) in Pakistan by using a novel dataset of monthly observations on cigarette prices in 50 cities during the period 2004 to 2015. The empirical analysis indicates that the pass‐through of cigarette taxes to the final consumer price is fast but incomplete in Pakistan. The pass‐through coefficient is estimated to be in the range of 70 to over 90 percent across four major cigarette brands, and most of the pass‐through occurs contemporaneously within a period of 2 months. The results imply that a 1‐Pakistan rupee (PR ) increase in taxation leads to an increase of PR s 0.8, on average, in cigarette prices. In other words, cigarette taxes are undershifted to consumers in Pakistan. With respect to the tax pass‐through at different price tiers (budget, mainstream, and premium), I find significant variation in the pass‐through coefficient, which is close to one for the premium cigarette brand and significantly lower for the budget and mainstream cigarette brands.     

When does tiered wholesale pricing create an incentive to reduce retail prices?

Wholesale ‘ladder pricing’ involves setting the wholesale price retailers face as a nonlinear (generally increasing) function of price chosen by retailers. This form of wholesale pricing occurred recently in UK Telecoms, and the issue became extensively debated in the law courts. A major concern in deciding the merits of the case lay with the question of whether or not the introduction of tiered wholesale pricing created incentives for retailers to actually reduce their prices. This paper examines the incentive for the case where the wholesale tariff is a non-linear continuous differentiable function. It is shown that so long as the tariff is strictly increasing, convex, and positive only for retail prices greater than the maximum retailer marginal cost, then there is indeed an incentive to reduce price, whatever the actual gradient of the tariff schedule.     

Using stochastic frontier models to mitigate omitted variable bias in hedonic pricing models: A case study for air quality in Bogotá, Colombia

Hedonic pricing models use property value differentials to value changes in environmental quality. If unmeasured quality attributes of residential properties are correlated with an environmental quality measure of interest, conventional methods for estimating implicit prices will be biased. Because many unmeasured quality measures tend to be asymmetrically distributed across properties, it may be possible to mitigate this bias by estimating a heteroskedastic frontier regression model. This approach is demonstrated for a hedonic price function that values air quality in Bogotá, Colombia.     

Estimates of foreign exchange risk premia: a pricing kernel approach

The goal of this study is to measure market prices of risk and foreign exchange risk premia. Estimations of minimum variance pricing kernels permit to determine market prices of risk, which, in an international no-arbitrage framework, allow to measure foreign exchange risk premia. Market prices of risk are time-varying and surge during financial turmoils. Foreign exchange risk premia are on average small in comparison to interest rate differentials and exhibit significant variation from the early 1970s onwards, when the Bretton Woods exchange rate system collapsed. At times, foreign exchange risk premia dominate interest rate differentials. We are indebted to Baldev Raj, Robert Kunst, the associate editor of Empirical Economics and two anonymous referees for their valuable comments. We also thank seminar participants at the European Central Bank, the Bank of England and Queen Mary University of London. The views expressed in this paper are those of the authors and do not necessarily reflect those of the European Central Bank or the Eurosystem.     

Deregulation of Shopping Hours: The Impact on Independent Retailers and Chain Stores

This paper studies shopping hour decisions by retail chains and independent competitors. We use a Salop‐type model in which retailers compete in prices and shopping hours. Our results depend significantly on efficiency differences between the retail chain and the independent retailer. If the efficiency difference is small, the independent retailer may choose longer shopping hours than the retail chain and may therefore gain from deregulation at the expense of the retail chain. The opposite result emerges when the efficiency difference is large. Then, the retail chain may benefit whereas the independent retailer loses from deregulation.     

Competition and confidentiality: Signaling quality in a duopoly when there is universal private information

We model non-cooperative signaling by two firms that compete over a continuum of consumers, assuming each consumer has private information about the intensity of her preferences for the firms' respective products and each firm has private information about its own product's quality. We characterize a symmetric separating equilibrium in which each firm's price reveals its respective product quality. We show that the equilibrium prices, the difference between those prices, the associated outputs, and profits are all increasing functions of the ex ante probability of high safety. If horizontal product differentiation is sufficiently great then equilibrium prices and profits are higher under incomplete information about quality than if quality were commonly known. Thus, while signaling imposes a distortionary loss on a monopolist using price to signal quality, duopolists may benefit from the distortion as it can reduce competition. Finally, average quality is lower since signaling quality redistributes demand towards low-quality firms.     

中国轿车行业的品牌价值及其动态变化趋势——基于特征价格模型的实证研究

中国轿车行业的品牌价值正处于动态变化的趋势之中。在控制产品差异化特征之后,外国品牌对本土品牌具有显著的溢价,但其溢价逐年递减;在4大类国别品牌中,欧系品牌具有显著的溢价,其溢价也在逐年递减;在10类企业品牌中,6个企业有显著的品牌溢价,1个有显著的品牌折价,其它品牌则不显著。轿车的车型特征与价格之间的关系并非简单的线性关系,而是呈现出"U型"的关系。这些研究结果有助于我们理解近几年来本土企业对自主品牌的发展战略所进行的调整。     

Shopping hours and price competition

This paper develops an argument why retail prices may rise in response to the deregulation of opening hours. We make this point in a model of imperfect duopolistic competition. In a deregulated market retailers view the choice of opening hours as a means to increase the degree of perceived product differentiation thus relaxing price competition. If the consumers’ preference intensity for time is sufficiently high the equilibrium configuration has asymmetric shopping hours where one retailer stays open for longer than the other. Both retailers charge higher prices than under regulation, and both are strictly better off.     

The bullwhip effect on inventory: a perspective on information quality

In recent years, there has been a vast increase in the quantity of information shared across supply chain. We investigate how the timeliness and accuracy of information quality affect the value of information sharing. We use the inventory bullwhip effect (BWE) to measure the value of information sharing in a two-level supply chain consisting of one retailer and one manufacturer. The retailer faces a price-sensitive demand and the price is an AR (1) process. Our study shows if customer demand and retailer’s immediate order are delayed, using retailer’s historical order quantity to forecast can decrease manufacturer’s BWE. If information errors happen, during delivery and utilization, information sharing is not always valuable for the manufacturer. Sometimes, no information sharing can decrease much more of BWE. If information errors occur when the retailer collects demand information, value of information sharing is more significant than when there are no information errors.     

Energy price shocks and milk price adjustments

Much previous research on energy price transmission sheds light on the relationship between oil prices and aggregate commodity prices, such as for agricultural products, or food price indexes. This letter uses data from 12 U.S. cities between 2001 and 2011 to examine how energy prices are transmitted to fluid milk products at the retail level. Results indicate the existence of an asymmetric energy pass-through (a rise is transmitted faster than a fall in prices) and that private label milk products are more insulated from energy price shocks and adjust at similar rate with national manufacturer brands.     

EXCHANGE RATE PASS‐THROUGH INTO RETAIL PRICES

We study exchange rate pass‐through and its determinants using scanner data on fast moving consumer goods sold by 1,041 outlets in the United Arab Emirates between 2006 and 2010. The data are augmented with country of origin information. Our main finding is that exchange rate pass‐through varies more across retailers within regions than across regions, and in particular that pass‐through increases with retailer market share. We also find that exchange rate pass‐through is negatively correlated with both product quality and the elasticity of substitution of the product category and positively correlated with the frequency of price adjustment.     

Vertical Control and Price Cycles in Gasoline Retailing

We examine Norwegian gasoline pump prices using daily station‐specific observations from 2003 to 2006. The four big gasoline companies use a vertical restraint that is adopted industry‐wide (labeled price support). This moves price control from the hands of independent retailers into the hands of the headquarters. Retail gasoline prices follow a fixed weekly pattern, where we observe de facto simultaneous decision‐making by the headquarters (without knowledge of their rivals’ prices) when every Monday around noon they decide to increase pump prices to the same level. The price level on Mondays corresponds to the recommended prices published by the headquarters of the gasoline companies.
