| In an imperfectly competitive industry, differentiated products compete with each other with price rather than quantity as the strategic variable. Several previous studies have employed a generalized Nash Bertrand model: Liang (1989), Cotterill (1994), Cotterill, Putsis and Dhar (2000), and Kinoshita, Suzuki, Kawamura, Watanabe and Kaiser (2001); however, only Liang has explored the theoretical foundations of that model. This paper generalizes the Liang two good model to three goods. A surprising and important result follows. Price conjectural variations do not exist in models with 3 or more goods. Price reaction functions, however, exist in multiple good models. We estimate them jointly with a brand level demand system to evaluate the total impact of a... |

| This article examines the effects of increasing market concentration level in the U.S. nitrogen fertilizer industry. Results indicate that the costs of market power are greater than the benefits of market concentration, in terms of manufacturing cost efficiency. To provide a stable nitrogen fertilizer supply at a relatively low price, it may be necessary to control natural gas price and/or reduce new import barriers from Middle East and former member states of the Soviet Union, where low cost gas is produced as a byproduct. Keywords: Nitrogen fertilizer, oligopoly, economies of size, market power, cost-efficiency. |

| Consumer product manufacturers often compete in dynamic, multi-firm oligopolies using multiple strategic tools. While existing empirical models of strategic interaction typically consider only parts of the more general problem, this paper presents a more comprehensive alternative. Marketing decision are dynamically optimal, consistent with optimal consumer choice, and responsive to rival decisions. Using a single-market case study that consists of five years of four-weekly data on ready-to-eat cereal sales, prices, and new brand introductions, we test several hypotheses regarding the nature of strategic interaction among several rival manufacturers. We find that cereal manufacturers price and introduce new brands cooperatively in the same period, but... |

| Market power is discussed in debates about subsidies for ethanol production. The structural conditions in the corn industry create a case for concerns about market power. We develop an analytical model for determining the production and price impacts and the distribution of benefits from the U.S ethanol subsidy when upstream sellers in the seed sector and downstream buyers in the processing sector may exercise market power. Results demonstrate that the impacts on prices and output are probably limited. Distribution impacts are much greater. Seed producers and corn processors with market power capture relatively large shares of subsidy benefits. |

| The Lanchester model of strategic interaction typically considers only two-firm rivalry and one strategic tool. This paper presents an alternative that considers rivalry among several firms using multiple tools. Marketing decisions are dynamically optimal and use equations of motion for market share that are consistent with optimal consumer choice. Using a single-market case study that consists of five years of monthly data on ready to eat cereal sales, advertising, product development investments and new product introductions, we test our model against a similar Lanchester specification. Non-nested specification tests fail to reject the proposed model, but reject the Lanchester alternative. |

| This paper develops a simultaneous-equations panel data econometric model to obtain point estimates of market power and pricing conduct in a representative product-differentiated, oligopolistic food market. The importance of this class of markets is recognized given its prevalence in the food and fiber system, especially for final consumer food products. The $1.3 billion domestic spaghetti sauce industry is featured. Although the results indicate firms exert limited market power, a portion of this power is derived from tacit price collusion. A higher degree of price collusion was found among brands within a market segment than between segments. |

| In many industries it is quite common to observe firms delegating the production of essential inputs to independent ventures jointly established with competing rivals. The diffusion of this arrangement and the favourable stance of competition authorities call for the assessment of the social and private desirability of Input Production Joint Ventures (IPJV), which represent a form of input production cooperation, not investigated so far. IPJV can be seen as an intermediate organizational setting lying between the two extremes of vertical integration and vertical separation. Our investigation is based on an oligopoly model with horizontally differentiated goods. We characterize the conditions under which IPJV is privately optimal finding that firms’... |

| This paper examines the relationship of 1987 retail grocery prices to supermarket sales concentration across 95 U.S. metropolitan areas. The regression model incorporates a large number of population, retail-cost, and retail competition factors and separate prices by type of grocery item. We find that the concentration-price relationship is sensitive to item type: positive for packaged, branded, dry groceries and unrelated for produce, meat, and dairy product prices. As for market rivalry, we find that small grocery stores provide no grocery price competition for supermarkets. However, branded grocery prices are driven down by fast-food places and by rapid price churning, whereas for unbranded foods the presence of warehouse stores places downward... |

| In the recent past, the concentration of seed maize processing and marketing in Kenya has raised serious public concerns. The inability of this industry to ensure affordable prices of certified seed maize for the farming community has led policy makers to question its market behaviour. In spite of these concerns, the performance of agricultural markets in Kenya has received little attention. This study evaluates the market conduct of the industry using the New Empirical Institutional Organization framework and tests the hypothesis of price taking behaviour. A system of five equations was used to estimate conjectural variations elasticity while a Lerner index was constructed to measure market power using data from Kenya's Central Bureau of Statistics. The... |

| In this paper, we analyse the market power of the retail industry in the French tomato market. Following the methods developed in the New Empirical Industrial Organization, we develop a structural model of this industry. The analysis is based on detailed data on final consumption and prices at both shipper and consumer levels for two types of tomatoes in France. The structural model is composed of a system of demand equations, supply equations and pricing equations which include terms which capture the oligopoly and oligopsony power of the retail sector. We show that i) elasticity of demand varies during the year ii) the retail sector exercise only a ‘moderate’ market power iii) the exercise of market power decreases over time iv) If markets were... |

| In Korea, processed food markets have various shapes of structure: the markets of ice cream, special dietary food, noodles, sugar are highly concentrated, while the markets of gimchi, pickles, and ice are not very concentrated. The level of market concentration changes over time. These market structures and structural changes cause impacts on related industries as well as own industries. For the more successful policies, the paper suggests three ideas: to realize that each food processing industry has a different industry structure, to understand the relationship between the food processing industry and upstream and downstream industries and to take into account opinions from various sources before adopting new policies. |
