| This paper shows that retailers may choose to offer products differentiated in quality to consumers, not to relax downstream competition, but to improve their buyer power in the negotiation with their supplier. We consider a simple vertical industry where two producers sell products differentiated in quality to two retailers who operate in separated markets. In the game, first retailers choose which product to carry, then each retailer and her chosen producer bargain over the terms of a two-part tariff contract and retailers finally choose the quantities. When upstream production costs are convex, the share of the total profits going to the retailer would be higher if they choose to differentiate. We thus isolate the wish to differentiate as "only" due to... |

| This paper examines whether ownership and increased competitive pressure affect food retailers’ market power, analysing whether all actors involved in the food supply chain deviate from the pricing behaviour that exists under perfect competition. A method proposed by Roeger (1995) is used to estimate price-cost margins, relaxing the assumptions of perfect competition and constant returns to scale. The obtained results show that foreign investments and consolidation have a positive and significant impact on the market power of food processors and retailers. Food processors, agricultural producers and wholesalers have lower price-cost margins than retailers, which suggests that these actors price closer to marginal costs being more concerned with maximising... |

| The 1990 Clean Air Act Amendments stipulated gasoline content requirements for metropolitan areas with air pollution levels above predetermined federal thresholds. The legislation led to exogenous changes in the type of gasoline required for sale across U.S. metropolitan areas. This paper uses a panel of detailed wholesale gasoline price data to estimate the effect of gasoline content regulation on wholesale prices and price volatility. In addition, we investigate the extent to which the estimated price effects are driven by changes in the number of suppliers versus geographic segmentation resulting from regulation. We find that prices in regulated metropolitan areas increase significantly, relative to a control group, by an average of 3.6 cents per... |

| In this paper we use a general model of imperfect competition to predict welfare changes within an open-access fishery transitioning to individual transferable quota (ITQ) management. Although related research has explored the effects of market power in the harvesting sector on ITQ performance, none have considered the implications of an imperfectly competitive processing sector. This study addresses this question specifically in the context of the Atlantic herring fishery, although its implications are relevant to all fisheries with similar industry structure. Our results show that ITQs could have a negative impact on fishermen’s welfare when processors have market power and the cap on aggregate harvest is binding or becomes binding with the... |

| 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. |

| In this paper different models of vertical relationships between manufacturers and retailers in the supermarket industry are compared. Demand estimates are used to compute price-cost margins for retailers and manufacturers under different supply models when wholesale prices are not observed. The purpose is to identify which set of margins is compatible with the margins obtained from estimates of cost, and to select the model most consistent with the data among non-nested competing models. The models considered are: (1) a simple linear pricing model; (2) a vertically integrated model; and (3) a variety of alternative (strategic) supply scenarios that allow for collusion, non-linear pricing and strategic behavior with respect to private label products. Using... |

| The objective of this paper was to verify the market power of the Argentinean, Brazilian and American exports of soymeal to the European Union, the main consumer market of this commodity. For that, the article is based on the methodology of residual demand. Using the methods Seemingly Unrelated Regression (SUR), Two-Stage Least Squares (2SLS) and Three-Stage Least Squares (3SLS), the results indicated that, though this segment is concentrated by Argentina, Brazil and the United States, none of these countries presented market power for soymeal exports. In other words, they are not able to change soymeal prices without to decrease the exports |
