ANALYZING VERTICAL MARKET STRUCTURE AND ITS IMPLICATIONS FOR TRADE LIBERALIZATION AgEcon
Sexton, Richard J.; Sheldon, Ian M.; McCorriston, Steve; Wang, Humei.
A model is developed to characterize the vertically linked and concentrated nature of developed country food markets. This model is then parameterized and used to simulate the effects of varying food market structures on the benefits to developing country exporters of agricultural commodities from trade liberalization by developed countries.

Buyer Market Power in UK Food Retailing AgEcon
Lloyd, Tim A.; McCorriston, Steve; Morgan, C. Wyn; Weldegebriel, Habtu T..
The potential existence of buyer market power in UK food retailing has attracted the scrutiny of the UK's anti-trust authorities, culminating in the decision to launch the second of two comprehensive regulatory inquiries in recent years. Throughout, detection of buyer power has been dogged by the paucity of reliable evidence of its existence. In this paper we present a simple theoretical model of oligopsony which delivers quasireduced form retailer-producer pricing equations in which the presence of market power can be detected using readily available market data. Using a cointegrated vector autoregression, we find empirical results that are consistent with the presence of oligopsony power in all six food products investigated.

Climate Policy, Carbon Leakage and Competitiveness: How Might Border Tax Adjustments Help? AgEcon
Sheldon, Ian M.; McCorriston, Steve.
In this paper, analysis is presented relating to the impact of border tax adjustments for climate policy on the international competitiveness of energy-intensive industries, and the related problem of carbon leakage. While many of the economic and legal issues are not particularly new, climate policy does present some possible twists to the analysis of border tax adjustments when vertically-related markets can be characterized as a successive oligopoly. Specifically, an appropriate border tax adjustment will depend on the incidence of a domestic carbon tax, the nature of competition in upstream and downstream sectors, as well as the basis for assessing the trade neutrality of any border tax adjustment. If trade neutrality is defined in terms of market...

Do Sales Matter? An Exploration of Price Discounting in UK Food Retailing AgEcon
Lloyd, Tim A.; Morgan, C. Wyn; McCorriston, Steve; Zgovu, Evious.
This paper assesses the impact of promotional activity in the prices of food products on supermarket shelves. The study analyses a unique, high frequency panel of supermarket prices consisting of over 230,000 weekly price observations on around 500 products in 15 categories of food stocked by the UK’s seven largest retail chains. In all, 1,700 weekly time series are available at the barcode-specific level including branded and own label products. Prices are inclusive of promotions and thus allow the frequency, magnitude and duration of sales to be analysed in greater detail than has hitherto been possible with UK data. Using this price data, sales periods are indentified. Results show that around 8% of products are on sale at any one time, and that sales...

Do Sales Matter? Evidence from UK Food Retailing AgEcon
Lloyd, Tim A.; Morgan, C. Wyn; McCorriston, Steve; Zgovu, Evious.
This paper assesses the role of sales as a feature of price dynamics using scanner data. The study analyses a unique, high frequency panel of supermarket prices consisting of over 230,000 weekly price observations on around 500 products in 15 categories of food stocked by the UK’s seven largest retail chains. In all, 1,700 weekly time series are available at the barcode-specific level including branded and own-label products. The data allows the frequency, magnitude and duration of sales to be analysed in greater detail than has hitherto been possible with UK data. The main results are: (i) sales are a key feature of aggregate price variation with around 40 per cent of price variation being accounted for by sales once price differences for each UPC level...

EXCHANGE RATE MISALIGNMENT AND AGRICULTURAL TRADE AgEcon
Cho, Guedae; Sheldon, Ian M.; McCorriston, Steve.
Using a sample consisting of bilateral trade flows across 10 developed countries between 1974 and 1995, this paper explores the effect of exchange rate misalignment on the growth of agricultural trade as compared to other sectors. Controlling for other factors likely to determine the growth in bilateral agricultural trade, the results show that long-run real exchange rate variability has had a significant negative effect on the growth of agricultural trade over this period.

EXPORT COMPETITION AND THE REMISSION OF DOMESTIC ENVIRONMENTAL TAXES AgEcon
McCorriston, Steve; Sheldon, Ian M..
In this paper we consider the use of border adjustments to compensate exporters for domestic environmental taxes even when the environmental tax is imposed on an intermediate good. Although GATT/WTO rules allow for border adjustments, there has been little analysis of them. A model of successive oligopoly is used to consider the appropriate border adjustments since many industries where environmental excise taxes are applied can be characterised as imperfectly competitive. We show that the border adjustment currently allowed for in GATT/WTO rules is, under certain circumstances, likely to be too low to maintain the competitiveness of exporters. In some cases, an export tax would be justified.

EXPORT SUBSIDIES AND PROFIT-SHIFTING IN VERTICAL MARKETS AgEcon
Sheldon, Ian M.; Pick, Daniel H.; McCorriston, Steve.
This study examines the interaction between export subsidies and profit-shifting in a vertical production system consisting of agricultural commodity production, and intermediate and final good processing, where the latter two stages may be characterized by imperfect competition. Using a model with general functional forms for demand, comparative statics indicate that an export subsidy to an unprocessed agricultural commodity, under certain circumstances, can have greater profit-shifting effects at the final processing stage compared to an export subsidy targeted at the final processed good.

IMPERFECT COMPETITION, TRADE POLICY AND PROCESSED AGRICULTURAL PRODUCTS: SOME INITIAL RESULTS AgEcon
McCorriston, Steve; Sheldon, Ian M..
This paper applies some recent developments in international trade theory to processed agricultural product markets. Theoretical results are derived showing that when such markets are characterized by imperfect competition, there may be a case for government intervention in the form of subsidies and tariffs. In order to provide some empirical background, a simulation model is used to assess the level of an optimal tariff on U.S. cheese imports. The implications of this analysis for the liberalization of agricultural trade are also considered.

Market Power and Relative Price Adjustment: Evidence from the UK AgEcon
Morgan, C. Wyn; McCorriston, Steve.
Empirical studies of price transmission often suggest that imperfect pass-through may be due to market power exerted by food retailers. However, these econometric studies essentially lack any formal basis for tying the role of market power with data comprising of retail and producer prices only. We show that if market power has an effect on the farm-retail margin, this determines the specification of the cointegrating relationship. To emphasise the relevance of the tests, we focus on results relating the UK beef sector and show that market power is likely to have played a role in determining the retail-farm price margin.

Market Power in UK Food Retailing: Theory and Evidence from Seven Product Groups AgEcon
Lloyd, Tim A.; McCorriston, Steve; Morgan, C. Wyn; Rayner, Anthony J.; Weldegebriel, Habtu T..
Establishing the presence of market power in food chains has become an increasingly pertinent line of enquiry given the trend towards increasing concentration that has been observed in many parts of the world. This paper presents a theoretical model of price transmission in vertically related markets under imperfect competition. The model delivers a quasi-reduced form representation that is empirically tractable using readily available market data to test for the presence of market power. In particular, we show that the hypothesis of perfect competition can be rejected if shocks to the demand and supply function are significant and correctly signed in price transmission equations. Using a cointegrated vector autoregression, we find empirical results that...

TARIFF ESCALATION AND THE DEVELOPING COUNTRIES: HOW CAN MARKET ACCESS BE IMPROVED IN THE DOHA ROUND OF TRADE NEGOTIATIONS? AgEcon
McCorriston, Steve; Sheldon, Ian M..
This paper explores the issue of market access where some developing countries export high-value processed goods and others export raw commodities. The results show that market access issues for goods entering at different stages of the marketing chain should take into consideration the potential existence of successively oligopolistic markets.

THE IMPACT OF FOOD SCARES ON BEEF AND INTER-RELATED MARKETS AgEcon
Lloyd, Tim A.; McCorriston, Steve; Morgan, C. Wyn; Rayner, Anthony J..
In this paper we investigate the impacts of food scares in the UK on the prices and spreads of beef, pork and lamb using a decade of monthly price data (1990-99). Results underline the importance of food scares on prices and price spreads and the strong inter-relationships between meats, typically ignored in such studies.

THE IMPACT OF FOOD SCARES ON PRICE TRANSMISSION IN INTER-RELATED MARKETS AgEcon
Lloyd, Tim A.; Morgan, C. Wyn; McCorriston, Steve; Rayner, Anthony J..
This paper is concerned with the impact of the BSE crisis in the UK and focuses on the spread between retail and farm prices. From a theoretical perspective we show that if market power has an effect on the spread between retail and farm prices then this determines the specification of the co-integrating relationship. We also account for different aspects of the BSE crisis including the shift in the retail demand function as well as the shift in the farm supply function due to the mutually opposing effects of a worldwide export ban and the cull of infected and older beef cattle. The empirical results suggest that the impact of the BSE crisis on farm prices to be more than double that of retail prices, the main cause of the change in the retail-farm price...

THE NON-NEUTRALITY OF WTO BORDER TAX ADJUSTMENTS FOR ENVIRONMENTAL EXCISE TAXES UNDER IMPERFECT COMPETITION AgEcon
McCorriston, Steve; Sheldon, Ian M..
Border tax adjustments for environmental taxes should leave imports of final goods unchanged. If intermediate and final goods markets are imperfectly competitive though, non-neutrality can result. Under Cournot behavior, an import tax equal to the environmental tax is too high, and under Bertrand, an import subsidy is the appropriate policy.

The Trade and Welfare Effects of State Trading in China AgEcon
McCorriston, Steve; MacLaren, Donald.
State trading is a common feature in the management of imports and exports of agricultural products and it has been a long-standing feature of China’s agricultural trade regime. While the use of state trading was modified by China’s accession to the WTO, it remains a dominant feature for some commodities, even although there have been recent attempts to diminish its importance. In this paper, we review the role that the state trading enterprise (STE), COFCO, continues to play in the importing and exporting of some agricultural commodities. We then review the economic theory that has been developed to measure the tariff equivalent of importing state trading enterprises. Finally, we apply that theory through a calibration exercise to measure the tariff...
