| 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... |

| 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 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... |

| 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... |

| 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. |

| The study examines the impacts of implementing mandatory country of origin labeling (COOL) on producer and consumer welfare in the U.S. meat industry. The equilibrium displacement model developed in this study includes twenty-nine equations representing retail-, processing-, and farm-level equilibrium conditions for the beef, pork, and chicken industries. Unlike previous studies, the model allows trade between domestic- and foreign-origin products and considers the imperfectly competitive market structure of meat processers. Empirical results show that without a significant increase in domestic meat demand, producers are not expected to benefit from the mandatory COOL implementation. Results of a sensitivity analysis indicate that consumers tend to bear... |

| Binary logit regression models were used to estimate factors affecting adoption of recommended management practices. Variables analyzed include aspects of farm structure, human capital, farm objectives, and production system employed by the producer. Results reveal that operation size and dependency upon income from the stocker operation, in particular, influence the adoption of recommended practices. Older producers and those pursuing a year-round production strategy were found to lag in adoption. |

| 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... |

| A two-step model with sample selection is applied to panel data of U.S. households to estimate at-home demand for fluid milk and cheese, incorporating advertising expenditures. The model consistently accounts for sample-selection bias, unobserved household heterogeneity, and temporal correlation. Generic advertising programs for fluid milk and cheese were effective at increasing conditional purchase quantities, with very little effect on the probability of purchase. In contrast to aggregate studies, the long-run generic advertising elasticities for cheese were larger than for those of fluid milk. Advertising response varied considerably across sub-product classes, while branded advertising expenditures were largely insignificant. |

| A two-step sample selection model is used to estimate household demand equations for fluid milk and cheese products incorporating national generic advertising. This approach allows us to disentangle the incidence of the advertising effect on the probability of purchase and changes in the level of consumption. Generic advertising for fluid milk had a predominantly intensive effect on athome fluid milk demand, implying that advertising was relatively more effective at increasing the consumption of current consumers. Conversely, the at-home cheese demand response to generic cheese advertising was almost exclusively extensive, with virtually the entire increase in quantity demanded due to an increase in the household’s probability of purchase. |

| 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 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... |
