| In this paper we estimate the price and income elasticities for five sweet spreads using a two-stage budgeting procedure. The first stage modeled the consumer's budget decision as a Tobit model, where total sweet spread expenditures are based on income and demographic variables. The second stage, including only those households with nonzero first stage expenditures, was treated as a standard consumer allocation problem using the AIDS model. To incorporate population demographics, the AIDS model was expanded by specifying the constant term as a linear function of demographic variables. The coefficients for the prices and expenditures are highly significant and demand is elastic for all five goods. The most significant demographic effects are due to... |

| This annotated bibliography presents an overview of the price transmission literature and reviews its application to agricultural product markets. The bibliography includes three types of articles: (i) theoretical pieces (early underpinnings through recent developments); (ii) empirical work on price transmission for agricultural products; and (iii) selected articles on specific agricultural products and the food industry. A brief synthesis of the articles is presented in the introduction. |

| An economic model was developed to gain an understanding of price flows in the markets for New York Red Delicious and New York McIntosh apples. Price transmission processes of two apple products, fresh apples and apple juice, are analyzed and compared. Specific emphasis is placed on evaluating price lags and price asymmetry, two factors which complicate the flow of prices between market levels. Results indicate that retail prices of fresh New York Red Delicious apples and fresh New York McIntosh apples respond more fully to wholesale price increases than wholesale price decreases. Results suggest that wholesale prices of fresh New York Red Delicious and fresh New York McIntosh apples are not determined by shipping point price increases and decreases.... |

| A national beekeeping-industry model, assuming rational expectations, is presented. Consistent and asymptotically efficient estimates are obtained by a modified two-step two-stage least squares method. Based on parameter estimates, elasticities, and likelihood functions, a previously estimated modified adaptive expectations model explains industry behavior better than the rational expectations model. Simulation analyses of the models suggest the direction of the impacts of an ineffective federal honey support program from 1982 through 1985 is similar but the magnitudes are varied. The rational expectations model indicates the decrease in beekeepers' revenue in this period is larger than the decrease identified by the modified adaptive expectations model. |

| A dynamic model of the U.S. apple industry, including relationships for bearing acres, production, utilization, and allocation to the fresh, canned, frozen, juice, dried and other markets, is specified. Demands for each of these markets are modeled. Model coefficients are obtained using Zellner's seemingly unrelated regression procedure and data from 1971 through 1990. Elasticities and flexibilities are compared with other studies. Projections indicate that price fluctuations will continue in the industry when acreage is held at 1990 levels. A ten percent increase in fresh exports strengthens all apple prices. However, a ten percent decrease in the price of juice imports mitigates some of this effect. |
