The theory of factor market distortions deals largely with taxing inputs. However, input subsidies are not only common in manufacturing. For example, U.S. agriculture is heavily dependent on input subsidies.
If water subsidies in the production of California cotton were removed, along with commodity payments, production of cotton in California would likely cease. Likewise, transportation subsidies were common in both the U.S. and Canada, and still prevail in the U.S.

“Commodity promotion” consists of many activities, each designed to contribute to a consumer’s product knowledge or influence tastes. However, both knowledge and tastes are unobservable, or latent, variables influencing demand. This paper specifies a dynamic structural model of fresh fruit demand that treats promotion and other socioeconomic variables as "causal" variables influencing these latent variables. Estimating this state-space model using a Kalman filter approach provides estimates of both the system parameters and a latent variable series. The results show that these latent effects contribute positively to apple and other fruit consumption, while reducing banana consumption.

A structural latent variable model of apple variety demand is used to analyze the effect of variety specific newspaper advertisement characteristics on variety attraction (preferences), and in turn on variety demand. The influence of advertisement size, the use of color and the Washington apple logo were analyzed. The estimated variety attraction variable is important in explaining demand. Model specifications which exclude this variable tend to understate demand elasticities. Advertisement size has a positive impact on Granny Smith, Fuji, and Gala sales. Red Delicious sales are positively influenced by color ads, but negatively affected by ads with the Washington apple logo.

The Fuji apple variety is relatively new in the U.S. As a new product, questions concern the relative impact of consumer learning by experience, by variety-specific promotion, or by generic apple promotion. A two-stage (LES/LAIDS) model incorporating both types of promotion is used to estimate the effect of generic and variety specific promotion, as well as consumer experience, on the demand for Fuji apples. Estimates show each to have a positive impact, and also show new or specialty apple varieties to be relatively price inelastic, but income elastic. Grower returns to promotion are calculated with an equilibrium displacement model of price changes and producer surplus. Changes in producer surplus provide a base-scenario benefit:cost ratio of 14.73.

Marketing research in consumer packaged goods shows that consumers’ brand choices, category choices, and purchase volumes are all affected by different factors and in different ways by pricepromotions
and advertising. Research also suggests that brand-loyalty, purchase rates, and inventory behavior are important determinants of category choice. These findings are likely to be true of apples as well.

Widespread obesity in the U.S. is a relatively recent phenomenon, reaching epidemic proportions only in the last 15 years. However, existing research shows that while calorie expenditure through physical activity has not changed appreciably since 1980, calorie consumption has risen dramatically. Consequently, any explanation of obesity must address the reason why consumers tend to overeat in spite of somewhat obvious future health implications. This study tests for an addiction to food nutrients as a potential explanation for the obesity epidemic. Specifically, we use a random coefficients (mixed) logit model applied to household scanner data to test a multivariate version of the rational addiction model of Becker and Murphy and Chaloupka. We find evidence of a rational addiction to all nutrients – protein, fat and carbohydrates – as well as to sodium, but particularly strong evidence of a forward-looking addiction to carbohydrates. The implication of this finding is that price-based policies – sin taxes or produce subsidies that change the expected future costs and benefits of consuming carbohydrate-intensive foods – may be effective in controlling excessive nutrient intake.
