| This paper applies the BLP approach to the demand for ready-to-eat cereals (RTECs) at the supermarket-chain level in Boston using IRI monthly data. The Random Coefficient Model is used to estimate the demand for 37 brands of RTECs at the leading supermarkets in the Boston area. The empirical results provide a wealth of consumer behavior information, including own- and cross-price elasticites for 37 brands of RTECs at four leading supermarkets in Boston. The demand for RTECs is generally price elastic (ranging between -3 and -8). Consumers respond positively and strongly to promotion, negatively and strongly to price, calories and fiber, and weakly to sugar content. Income has a strong interactive effect with product characteristics and thus is a useful... |

| The rising obesity during the past three decades poses a severe public health challenge and spurred enormous research interests. This paper contributes to the growing literature on how obesity spreads by empirically investigating whether social norms affect soft drink consumption choices. Combining market level soft drink scanner data and survey data with consumer level characteristics, we employ reduced form regressions to test whether social norms of body weight affects per capita consumption of total or caloric soft drink consumption, on a market level. We also utilize a random-coefficient logit model to examine whether social norms of body weight affect consumer choices on a brand level. Our results from the market level analyses support that a heavier... |

| This article examines the influence of campaign contributions on agricultural subsidies. Empirical results revealed that rent seeking works, i.e., campaign contributions of agricultural-related industries influence agricultural subsidies in the manner they best serve contributors' economic interests. Eliminating campaign contributions would significantly decrease agricultural subsidies, hurt farm groups, benefit consumers and taxpayers, and increase social welfare by approximately $5.5 billion. Although contributions are not the only determinants of agricultural subsidies, investment returns to farm PAC contributors are quite high ($1 in contributions brings about $2,000 in policy transfers). In fact, the results are in sharp contrast to the "truthful... |

| The thrust of this paper is to identify and measure structural changes in the U.S. demand for sugar and to derive subsequent implications for import restriction policies. Empirical results indicate that changes in consumer preferences and the availability of closer and cheaper sweeteners in food processing, especially high fructose corn syrup (HFCS), are exerting a downward pressure on sugar demand. As the U.S. demand for sugar decreases and the food industry adjusts faster to sweetener choices, the U.S. government would have to impose more restrictive import barriers to maintain prices to domestic sugar and HFCS producers. Furthermore, the welfare impact of U.S. sugar policy options on domestic consumers and food processors will be lessened. |

| This paper investigates the effect of in-store services on retail food prices, supermarket competition, and demand using fluid milk as a case study. It is shown that higher-service supermarkets charge higher milk prices essentially because of an increase in market power due to differentiation of service offering. Results show that different types of services impact milk prices differently, that upscale food-retailers face stronger competition in newer services, and that service competition results in a trade-off for the consumer between the attractiveness of the enhanced retail configuration and the increase in prices. |

| The objective of this article is to provide an overview on constraints and opportunities for increased vegetable trade in the Americas. The realization of this potential will likely be constrained by the extent of the market, immigration reform in the United States, lack of investment capital in Latin America, high transportation costs of fresh produce, and quality and health concerns of consumers. Opportunities are more apparent in selected world areas (Asia, European Community, United States, and Canada), for high quality, fresh rather than processed vegetables with safe or zero levels of pesticide and chemical residues, especially due to consumers' concern for a healthier diet. Whether or not the potential for expanding vegetable trade will be realized... |

| The objective of this article is to estimate historical economic surpluses for the subsectors involved in the U.S. sugar market. Annual producer and consumer surpluses were computed based on a five-equation model and 1958-87 data. In the last decade, the welfare position of cane- and beet-sugar producers has been roughly maintained, the domestic consumer surplus and the export quasi-rents to foreign countries have both declined, and quasi-rents of the corn-sweetener industry now surpass those that accrue to the cane industry and are about the same as those of the beet-sugar industry. Some policy implications are discussed. |

| This paper examines the potential benefits of introducing a new payment scheme in a sugarcane processing cooperative. Findings suggest that a use-value payment system would increase individual and total members’ net returns significantly over a sugar-based system. The proposed payment system would change the incentive structure so varieties with higher processing quality would become more appealing. In addition, the cooperative plant would be used more uniformly throughout the processing season and payments to members would be more consistent with their contribution to cooperative surplus. |

| We apply the Berry, Levinsohn and Pakes (1995) market equilibrium model (BLP) to data from 30 brands of beers sold in 12 U.S. cities over 20 quarters (1988-92) to estimate the consumers taste for beer characteristics (price, alcohol content, and calories) as well as for the cultural region of origin (USA, Anglo-European, Germanic, and countries bordering the U.S.). Consumer heterogeneity is allowed with respect to age, income and gender. Overall we end up with 7,200 beer brand observations (30x12x20) and 13,920 (58 random draws x 12 x 20) consumer observations. Empirical results indicate that indeed there is home bias with respect to European beers and somewhat less so with respect to beers from bordering countries (Mexico and Canada). Home bias is more... |

| This paper uses Data Envelopment Analysis to measure scale and technical efficiencies of 925 farms in rural Colombia and a Tobit model to identify the effects of land market characteristics on efficiency. Findings indicate that although larger farms are more scale efficient, they are not more technical efficient than small farms. Participation in land markets increases technical efficiency, indicating a positive potential role for market-based land reform. Further results show that intensity of violence in rural areas results in increased scale efficiency, allegedly through consolidation of land ownership. |

| This paper ascertains the costs and benefits of diverting water from the Senegal River. Two scenarios are compared to the status quo of inaction: the social planner and the competitive scenarios. Although these two scenarios yield positive present values of net benefits, the social planner scenario would use smaller quantities of water while providing the highest net benefits to society. Given that the benefits are one-sided while the costs are spread over several constituencies that share the river, it is possible for the gainers to compensate the losers, especially the farmers of flood recession agriculture identified as the main deprived group. |

| This paper estimates farm household levels of technical efficiency and their determinants in Colombia, with particular reference to political violence (i.e., guerilla fronts, assassinations, kidnappings, and displaced population). An input-oriented stochastic frontier is estimated simultaneously with a technical inefficiency model that incorporates violence at the local level, using survey data from 822 farm households. The findings show that household productivity is lower in areas of high political violence, particularly with high incidence of guerrilla fronts and kidnappings. Should political violence be eliminated, the average Farrell's technical efficiency index of farm households in the sample would increase by an average of 6.4%, favoring households... |
