Investigating first‐stage exchange rate pass‐through: Sectoral and macro evidence from euro area countries

In this paper, we evaluate the first‐stage pass‐through, namely the responsiveness of import prices to the exchange rate changes, for a sample of euro area (EA) countries. Our study aimed to shed further light on the role of microeconomic factors versus macroeconomic factors in influencing the extent of the exchange rate pass‐through (ERPT). As a first step, we conduct a sectoral analysis using disaggregated import prices data. We find a much higher degree of pass‐through for more homogeneous goods and commodities, such as oil and raw materials, than for highly differentiated manufactured products, such as machinery and transport equipment. Our results confirm that cross‐country differences in pass‐through rates may be due to divergences in the product composition of imports. The higher share of imports from sectors with lower degrees of pass‐through, the lower ERPT for an economy will be. In a next step, we investigate for the impact of some macroeconomics factors or common events experienced by EA members on the extent of pass‐through. Using the system generalised method of moments within a dynamic panel‐data model, our estimates indicate that decline of import‐price sensitivity to the exchange rate is not significant since the introduction of the single currency. Our findings suggest instead that the weakness of the euro during the first 3 years of the monetary union significantly raised the extent of the ERPT. This outcome could explain why the sensitivity of import prices has not fallen since 1999. We also point out a significant role played by the inflation in the Eurozone, as the responsiveness of import prices to exchange rate fluctuations tends to decline in a low and more stable inflation environment. Overall, our findings support the view that the extent of pass‐through is comprised of both macro‐ and microeconomic aspects that policymakers should take into account.     

Price matching and product differentiation strategies considering showrooming

Showrooming, a phenomenon in which customers use brick-and-mortar stores to assess products and then purchase them from online retailers (o-retailers) for lower prices, is considered a great threat to traditional retailers (t-retailers). To combat showrooming, many t-retailers have executed price matching which enables customers to pay o-retailers' lower prices for the identical product. To avoid direct competition with t-retailers who execute price matching, many o-retailers have begun to sell differentiated products from t-retailers, which weakens the information advantage to customers from practicing showrooming. Motivated by these observations, we construct a duopoly game, where a t-retailer and an o-retailer sell products in a same category, to study the profitabilities of product differentiation and price matching in the context of showrooming. The results show that in the scenario without price matching, the o-retailer is likely to benefit from product differentiation only when the o-retailer's differentiated product is more popular with customers than the t-retailer's product. However, in the price matching scenario, the o-retailer also has the opportunity to benefit from product differentiation when the o-retailer's differentiated product is less popular with customers than the t-retailer's product, and product differentiation can be a win-win strategy for the two retailers under certain conditions. Considering the o-retailer's product differentiation decision, the t-retailer is only likely to execute price matching if the non-digital attributes of the product category sold by two retailers are not very obvious.     

Explaining import quality: The role of the income distribution

We examine a generalized version of Flam and Helpman [Flam, H., Helpman, E., 1987. Vertical Product Differentiation and North-South Trade. American Economic Review, 77, 810-822.] in which consumption prices for quality differentiated goods are rising in household income. We provide propositions for aggregating this relationship across heterogenous households to map cross-country differences in income distributions to cross-country differences in import price distributions. The theoretical predictions are examined and confirmed using disaggregated data on prices of traded goods and micro data on household income from the Luxemburg Income Study. Country pairs with more similar income distributions have more similar import price distributions, whether similarity is measured by 1st-4th moment statistics, population and consumption shares within world income and product price quantiles, or income and price dis-similarity indices.     

Erratum to: Competitive price-matching guarantees under imperfect store availability

This paper analyzes the role of verification of product availability in the context of competitive price-matching guarantees (PMGs). PMGs involve a retailer matching any lower price offered by competition for an identical item. Until now, researchers focused on the scenario where customers can receive the lower price with a simple proof (e.g., weekly flyers). However, in reality, retailers reserve the right to verify the availability at the competitor location; if the product is not available there, then the price-match request might be declined. We develop a price competition model to investigate the effects of verification of availability on price decisions and profit levels of competing retailers. In our model, demand is driven by the availability levels of retailers as well as the price-search cost and store-switching cost incurred by customers. Price-search cost leads to two customer segments: uninformed ones who have no knowledge about prices, and informed ones who are knowledgeable about prices. On the other hand, store-switching cost determines how many customers search for the product at an alternative location because of high price or unavailability at their preferred retailers. Our analysis reveals, among others, that the outcome of availability verification is linked to three factors: price-search cost, store-switching cost, and the reservation prices of customer segments. Verification of availability allows retailers to price discriminate customers who could not be discriminated otherwise, specifically those belonging to the informed customer segment. Furthermore, it is a significant profit-enhancing mechanism only if there are switching customers in the market. Interestingly, even though customers view the verification of availability as a hassle, it can actually result in them paying lower retail prices by increasing the level of retail price competition.     

Regional Taxation and Retailing: The Economic Geography of the Internet

It is well established in the economics literature that before-tax prices are not independent of sales-tax rates. This paper shows that a sales-tax imposed in a high tax region can decrease the tax-included price for a buyer in a low tax region who purchases from a seller in the high tax region. Therefore, it may be more profitable for Internet retailers to be located in high tax regions. An empirical analysis shows that automobile manufacturers in the European Union (EU) set higher before-tax recommended prices for countries with low indirect taxes. This may contribute to the explanation of the flow of Internet automobile sales from high tax countries to low tax countries in the EU.     

The Extensive and Intensive Margins of Exports: The Role of Innovation

An important prediction of trade theories is that innovation can improve a country’s export performance. Using data on patents granted by the US as a proxy for innovation and data on manufacturing exports from 105 countries over the period 1975–2001, I investigate the extent to which innovation increases the number of products traded (the extensive margin) and the export value of each product (the intensive margin). The empirical results show that (i) innovation has a positive and significant effect on both the extensive and intensive margins. The intensive margin contributes 70 per cent of the effect, and the extensive margin accounts for 30 per cent. (ii) The effect of innovation on exports is stronger for low‐income countries than for high‐income countries. (iii) More innovative countries export greater quantities and charge higher prices, suggesting that innovation increases the product quality of exports.     

Same but different - The effect of the unit of measure on the valuation of a unit price

Unit prices are a ubiquitous phenomenon. The respective legal norms leave a certain freedom of choice with regard to the reference unit. However, research on the impact of alternative measurement units on consumer behaviour is still in its infancy and its findings are inconclusive. Moreover, this influence has so far only been measured directly. Investigating the product category bottled beer (with its essential product attributes ‘brand’, ‘price’, ‘alcohol content’ and ‘size of packaging unit’), a Choice Based Conjoint experiment provides empirical evidence that a large (per 1 L) compared to a small (per 100 mL) size unit of measurement leads to a significant shift of importance towards the product attribute ‘price’ at the expense of the ‘brand’. In addition, consumers react more sensitively to price changes. At the strategic level, retailers can use these insights to sharpen their positioning through a suitable unit price measure. When making operational decisions, retailers should bear in mind that the reference unit influences the likelihood of purchase, the scope for price increases and the opportunities for up-selling.

Distributional Effects of Public Investment when Wealth and Classes are Back

In developed economies, wealth inequality is high, while public capital is underprovided. Here, we study the impact of heterogeneity in saving behavior and income sources on the distributional effects of public investment. A capital tax is levied to finance productive public capital in an economy with two types of households: high income households who save dynastically and middle income households who save for retirement. We find that inequality is reduced the higher the capital tax rate is and that low tax rates are Pareto‐improving. There is no clear‐cut trade‐off between efficiency and equality: middle income households’ consumption is maximal at a capital tax rate that is higher than the rate which maximizes high income households’ consumption.     

Vulnerability to Low-Price Signals: An Experimental Study of the Effectiveness of Genuine and Deceptive Signals

Low-price guarantees help buyers make inferences about retailers’ prices. However, researchers are concerned that consumers might be vulnerable to relying on guarantees associated with high market prices. Furthermore, truly low-priced retailers that issue low-price guarantees might be vulnerable to consumers’ discounting of such guarantees. This article experimentally assesses these concerns and finds that the effects of adding a low-price guarantee to a low or high offer price on consumers’ pre-purchase perceptions depend on consumers’ confidence in their product category price knowledge and their decision involvement. The article explores the implications of the findings and provides directions for further research.     

Pricing behavior in the online DVD market

Using a data set with of 5508 observations collected in the online DVD market, we compare the pricing behavior between online branches of multi-channel retailers (MCRs) and online-only retailers. We find that (1) prices by online-only retailers are lower than prices by online MCRs by an average of $1.51 or 6.8 percent; (2) the price dispersion for the popular titles is sharply lower among online-only retailers than that among MCRs online; and (3) online-only retailers change prices more often than online MCRs although price changes by both types are few. The evidence suggests that the pricing efficiency diminishes as the multi-channel retailing format dominates the online retailing market.     

Supply Chain Networks and Electronic Commerce: A Theoretical Perspective

In this paper, we develop a framework for the formulation, analysis, and computation of solutions to supply chain network problems in the presence of electronic commerce. Specifically, we consider manufacturers who are involved in the production of a homogeneous product and can now sell and have delivered the product not only to retailers but also directly to consumers. In addition, the manufacturers can transact with the retailers electronically. We assume that both the manufacturers and the retailers seek to maximize their profits, whereas the consumers take both the prices charged by the retailers and the manufacturers, along with the associated transaction costs, in making their consumption decisions. We identify the network structure of the problem, derive the equilibrium conditions, and establish the finite-dimensional variational inequality formulation. We then utilize variational inequality theory to obtain qualitative properties of the equilibrium pattern. In addition, we propose a continuous time adjustment process for the study of the disequilibrium dynamics and establish that the set of stationary points of the resulting projected dynamical system coincides with the set of solutions of the variational inequality problem. Finally, we apply an algorithm for the determination of equilibrium prices and product shipments in several supply chain examples. This paper synthesizes Business-to-Consumer (B2C) and Business-to-Business (B2B) decision-making in a supply chain context within the same framework.     

Buyer Power,Transport Cost and Welfare

Manufacturers produce substitute products and sell to consumers in a linear city through competing retail stores. A low cost store obtains large market share by selling at low prices. Assume that a big retailer may exert buyer power by demanding wholesale discounts from manufacturers. The model identifies exclusionary effects of buyer power against competing retailers. It is also found that certain level of buyer power of a discount retailer may maximize social welfare, while that of a regular price retailer may maximize total consumer surplus. Nevertheless, excessive buyer power hurts both consumers and society.     

Revisiting low price guarantees: Does consumer versus retailer governance matter?

Retailers often use low price guarantees (LPG) as a signal to attract consumers and increase sales. Consumers interpret LPGs as a signal that a particular retailer is committed to low prices. However, if more and more retailers employ LPGs, their effectiveness as a price signal wears off. As a result, retailers adapt increasingly extreme guarantees to get an advantage over the competition. Retailers, for instance, are experimenting with taking on the responsibility of looking for lower prices and automatically refunding consumers when a competitor offers a lower price for the same product. This research shows that automatic price protection of this sort might backfire under certain conditions. Three studies show that LPGs alone are not enough to signal low prices and that retailers combining large refunds with a retailer-enforced LPG obtain less favorable reactions than those implementing other types of LPGs.     

Does Monetary Integration Reduce Exchange Rate Pass‐Through?

There are several theoretical arguments for why the adoption of a common currency (either a currency union or a currency board) may reduce the exchange rate pass‐through (ERPT) to domestic consumer prices. This paper examines a broad panel of 101 countries over the period 1976–2006, using two‐stage instrumental‐variable estimation techniques in order to resolve the potential endogeneity problem. The main result is that ERPT indeed tends to decline in countries participating in a common currency arrangement. In particular, there has been a strong reduction in pass‐through in the member countries of the European Monetary Union (EMU) since the launch of the euro. Currency boards do not appear to be different from currency unions – both reduce the pass‐through from depreciation to inflation. Furthermore, the negative impact of common currencies on ERPT is at work in both high‐income and low‐income countries. Finally, most of the reduction in pass‐through to consumer prices under common currency arrangements happens somewhere along the pricing chain between the border and the supermarket shelf.     

Compete in Price or Service?—A Study of Personalized Pricing and Money Back Guarantees

Retailers use both pricing and service strategies to respond to intensified competition. Here we develop a duopoly model to investigate the impact of the increasingly popular personalized pricing strategy (PPS) and the widely used Money Back Guarantee (MBG) customer returns policy. We consider two retailers who differ in customer satisfaction rates. Each retailer chooses a pricing strategy, PPS or uniform pricing, and a product return strategy, MBG or ‘no returns.’ We show that both PPS and MBG are dominant strategies, but their impact on retailers’ prices and profits are different; while PPS intensifies price competition and may lead to a prisoner’s dilemma in which both retailers may lose profit, MBG mitigates price competition and may result in a Pareto improvement in both retailers’ profits. Both PPS and MBG increase the size of the overall market, but not the total duopoly profit. The total customer surplus and social welfare may increase under either strategy. In addition, we obtain some interesting observations as to how our results may change if the product quality/customer satisfaction rate is endogenously chosen in the duopoly. Some of our findings are in contrast to related results reported in the literature.     

Analysing consumers' ‘activism’ in response to rising prices

The purpose of this paper was to compose the profile of active consumers in Greece during a period of rising prices taking into account shifts in their consumption. A survey was conducted from 1 September 2008 to 21 November 2008 to collect the primary data source for the study. Questionnaires were administered to 200 consumers. To our knowledge this was the first attempt to offer insight into the characteristics of the Greek consumer in a period of economic crisis. For this purpose, econometric analysis was employed. Empirical results suggested that high‐income groups spend more for food commodities and are less likely to be active consumers. It was concluded that consumers have reduced spending for some basic and semi‐luxury products like fruits, meat, alcohol, sweets and coffee, and entertainment activities. The main factor which affected the reaction to price increases, as expected, was the monthly private income. Twenty per cent of the consumers are members of a national consumer movement organization, and support their actions against rising prices. Women, who research the market before purchasing a product, are more likely than men to participate in economic boycotts. By examining the profile of non‐active consumers and the reasons for their behaviour, we are able to propose a policy for the activation of the Greek consumer movement, which is necessary for the consumers' resistance to rising prices. Taking into consideration that Greek consumers face increased prices for food commodities and services, a policy framework to activate consumers is among the main prerequisites for maintaining consumers' well being. We suggest that the Greek Consumer Protection Institutes should regain consumers' confidence and focus on the dissemination of information about organized economic boycotts.     

Tie-in contracts with downstream competition

A tie-in contract has frequently come under scrutiny for its role as an exclusionary device. A firm that is a monopolist in a primary market can utilize such contracts to exclude a more efficient rival in a secondary market. When the firms sell through competing retailers, the leveraging firm may offer tie-in contracts to the retailers inducing them to purchase both primary and secondary products entirely from it such that the rival is excluded. We examine whether such tie-in contracts are profitable for an incumbent firm under different conditions of (i) the ability to commit to prices by the upstream firms and (ii) downstream competition among the retailers. We show that when retailers compete in prices, then regardless of whether the entrant is able to commit to its own prices, an exclusionary tie-in strategy is profitable (not profitable) for the incumbent when it is able (unable) to commit to prices. However, when retailers compete in quantities, the entrant’s commitment ability does matter. Specifically, an exclusionary tie-in strategy (i) may be unprofitable for an incumbent when both upstream firms are able to commit to their prices, depending on the degree of cost advantage of the entrant; (ii) is always profitable when it alone can commit to its price; and (iii) is unprofitable when both upstream firms cannot commit to their prices. Our results extend to situations where the products are complementary or substitutes and where the retailers may be asymmetric in nature.     

Manufacturers' brand advertising and how it influences manufacturers' and retailers' margins

This article describes the effects of manufacturers' brand advertising on the costs, margins and prices of firms in a real-life, 'dual-stage' world where manufacturers sell to retailers who resell to consumers. Unlike 'single-stage' models, which are frequently used by economists, in which manufacturers appear to sell directly to consumers or to deal with them through an inert distribution system, retailers in a dual-stage world neither buy nor sell as perfect competitors. Although in some industry structures advertising will raise prices to consumers, the welfare effects of advertising are far more benign in a dual-stage world. In intensively advertised categories consumers are more disposed to switch stores within brand than brands within store (just the opposite of relationships in categories where brand franchises are weak) causing there to be an inverse association between margins at the two stages. Thus, while intensive advertising will normally raise factory prices it will drive down retailer margins, often to the point that retail prices are below the levels that would be obtained if the industry were only lightly advertised.     

Quality-adjusted price comparison of non-homogeneous products across Internet retailers

This study compares prices offered by multiple Internet retailers. This task is challenging because e-tailers cannot present their entire assortments to each consumer. Therefore, the quality of the product assortments presented by different e-tailers to each consumer is not directly comparable on an item-by-item basis, resulting in non-homogeneous offerings across retailers. We further consider the interaction between retailers (product information presentation format) and consumers (product information search strategies), which makes price comparisons among the retailers even more non-homogeneous. To grapple with this quality-adjusted price comparison problem for non-homogeneous products, we use a stochastic-frontier hedonic-price regression model to find the “lowest” theoretical price for a product given its characteristics. We then assess the price efficiency of the product as the ratio between this lowest price and the offered market price. This framework allows for the comparison of retailers in their ability to offer the “best deals” even when their actual assortments are not directly comparable in quality. Moreover, this framework provides Internet retailers with a relative measure of price efficiency. This helps them understand when and where they offer competitive prices to consumers. We illustrate our approach empirically in a comparison of price efficiency among three major Internet travel agents on a sample of posted itineraries and airfares. Furthermore, we demonstrate that the price efficiency of an Internet travel agent depends on the format of its website and on consumers' search strategies.
