Recently, the U.S. Supreme Court considered whether the mandatory fees imposed by the beef checkoff violates the First Amendment. As a precaution, many states began forming voluntary beef checkoffs, where funds would be raised through voluntary contributions. This study conducted a survey of Oklahoma cattle producers to determine what type ofvoluntary checkoff design would receive the greatest support. The most popular checkoff placed a large emphasis on advertising and a slightly lower checkoff fee. The survey also tested the ability of a provision point mechanism to limit free-riding. The mechanism was not as effective as in other studies which used laboratory experiments.

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.

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 differences in firm-level supply elasticities and firm sizes, and experience large demand shifts due to advertising programs
