| This report examines the responsiveness of fluid milk sales to milk advertising in the New York City, Albany, Syracuse, Rochester, and Buffalo markets. Fluid milk demand equations for New York City, Albany, Syracuse, Rochester, and Buffalo were estimated with monthly data from 1986-2000, which included generic milk advertising expenditures Generic milk advertising had a positive impact on milk sales in all markets, and was statistically significant in three out of the five markets. The model was then simulated to determine the impact of the New York state portion of advertising expenditures on producer milk prices and returns. A benefit-cost ratio was also computed for each market, and the weighted average for New York state was equal to 2.12 indicating... |

| This study develops an analytical framework to examine the impact of generic advertising on brand advertising with alternative assumptions on demand changes (shift-up and rotation), product differentiation, market concentration, and relationship between commodity and brand advertising programs. The newly developed model allows one to determine the relationship between generic and brand advertising, which has not been clearly shown in previous studies. Analytical results show that when generic advertising leads to an inelastic demand, generic advertising would help brand advertising and could decrease the optimal brand advertising expenditures. However, when generic advertising leads to an elastic demand, it would negatively affect the profitability of... |

| The study develops a Muth-type equilibrium displacement model that is able to estimate impacts of COOL on multistage beef production system and its trade relations. The model includes equilibrium conditions of each production stage with consideration of trade and market structure. A unique feature of this model is that it allows for retailer's oligopsony power separately from processor's market power. Simulation results indicate that the cost of COOL would outweigh the overall industry benefit unless COOL leads to low cost increases and more than a 10% increase in consumers' willingness to pay. The COOL provision is expected to have relatively smaller negative impact on cow-calf producers, backgrounders, and feedlots than on packers and retailers. |

| This study develops an alternative way of identifying the heterogeneity of WTP estimates for product attributes. The alternative approach combines mixed logit models with a latent segmentation method (MLS). First, the combined MLS approach estimates a mixed logit model and retrieve individual specific parameter estimates based on individual specific posterior distribution derived from the individual sequence of observed choices in the conjoint experiments. Second, WTPs of each choice variables are computed for each individual using the marginal rate of substitution between economic and choice variables. Finally, latent segmentation is conducted based on WTPs, individual perceptions on quality attributes, and demographic characteristics, and WTPs are... |

| The purpose of this study is to investigate whether the generic advertising helps or hurts the brand advertising within the differentiated product environments. We develop an analytical model that includes both generic and brand advertising expenditures considering vertical product differentiation. Then the analysis is devoted to examine how marginal effects of expenditure affect each other under product differentiation. To help examine the relationship, we also include a new variable, the degree of product differentiation. Analytical results show that when the generic advertising increases the product differentiation, the high quality brand tends to take benefits while the low quality brand loses. When generic advertising includes messages that do not... |

| This study presents a theoretical and empirical analysis of the distribution of generic advertising benefits across individual producers. We develop a closed-economy partial equilibrium model that allows for the presence of producer heterogeneity in supply response. Analytical results indicate that producers having less elastic supply response capture more benefits per dollar expended than producers with more elastic supply response. The extent of unequal distribution depends on parameters characterizing industries. The inequality may not be a significant problem for some industries, especially where the firm-level supply elasticities are not substantially different among producers, but it may be an important issue when industries have substantial... |

| Using a linear programming model, this study evaluates the effects of commercializing new biotech-soybean varieties on the livestock producers feed costs and formulations. Major findings include: (1) development of new alternative soybeans would benefit poultry meat producers more than egg and pig meat producers; (2) new soybean meals would save more feed costs in starter diets than in either grower or finisher diets; and (3) economic advantages of new soybean meals were highly sensitive to the availability of alternative protein sources but less sensitive to changes in ingredient prices. |

| In this study, we examine the distributional effects of research versus consumer promotion. A few years ago, a notable article by Wohlgenant (AlAE 75, 1993) investigated this issue and concluded that producers would benefit more from research on farm-level production than from research on marketing services and promotion. His findings have drawn important policy implications for the allocation of checkoff funds, especially for those producer groups (e.g., dairy, beef, and pork) who spend a large share of their funds on consumer promotion. We challenge his conclusions. We contend that his findings are confined to a special case, the parallel shift in demand and supply. To verify our claim, we reexamined his findings with an alternative case, a pivotal... |

| This article develops a varying-parameter advertising model which specifies advertising parameters as a function of variables representing advertising strategies and market environments to explain the varying nature of the advertising responses. Unlike prior models, this model allows researchers to examine the sources of change in advertising effectiveness over time. The model is applied to the New York City fluid milk market for the period from January 1986 through June 1995. Results indicate that advertising strategies and market environments play important roles in determining advertising effectiveness. Particularly, demographic factors were more important than economic factors. The results also suggest that when a market is in an unfavorable or... |

| This study asks the question, what is the relationship between traditional models of market power and structural auction models? An encompassing model is derived that considers both price markdowns due to bid shading during an auction and price markdowns at the industry-level due to imperfect competition. Data from a cattle procurement experimental market is used to compare the appropriateness of the two alternative theories. Regression results show that while the number of firms is more important than the number of bidders on lot of cattle in explaining pricing behavior in the game, the number of bidders does contain some unique information and should be included in the model. Both the traditional NEIO and structural auction approaches overestimated... |
