| 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... |

| 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. |

| 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... |

| 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... |

| 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 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... |

| 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. |
