| This paper examines several approaches to introduce advertising in systems of demand equations. Advertising is included in the Rotterdam model using an unrestricted specification and three restricted specifications - advertising affects demand alternatively through (1) marginal utilities as in studies by Duffy (1987, 1989, 1990) and Selvanathan (1989), (2) scaling parameters which can be viewed as indicators of product quality, and (3) translation parameters which can be viewed as indicators of basic needs. A test to choose among the alternative specifications is provided and the methodology is applied to data on demand for fruit juice products. |

| This study analyzes the historical price response of individual crop acreage in order to determine the impacts of an expansionist policy in bioethanol production on the U.S. agricultural industry. In doing this, this study provides an economic foundation by using a traditional Rotterdam model to simulate a cropland demand system. Within the developed framework, this study estimates own and cross acreage elasticities and scale elasticities to show the impacts of acreage values on crop production and the relationship between total cropland and individual crop acreage. This study found that rice farming is most inelastic to own acreage value. Soybeans, hay, and wheat are shown to be good substitute crops for corn. Corn, soybeans, hay, wheat, cotton, barley,... |

| We estimate the demand for imported cotton in China and assess the competitiveness of cotton-exporting countries. Given the assertion that developing countries are negatively affected by U.S. cotton subsidies, our focus is the price competition between the United States and competing exporters (Benin, Burkina Faso, Chad, Mali, India, and Uzbekistan). We further project how U.S. programs affect China’s imports by country. Results indicate that if U.S. subsidies make other exporting countries worse off, this effect is lessened when global prices respond accordingly. If subsidies are eliminated, China’s cotton imports may not fully recover from the temporary spike in global prices. |

| Very little is known about changes in the demand characteristics of food in New Zealand. As far as we can determine, there has never been a complete disaggregated food demand model estimated for New Zealand. The object of this paper is to update these estimates using more recent data to see whether there are grounds for believing that the structural changes that occurred primarily during the last two decades are having effects on the magnitude of food demand elasticities in New Zealand. To this end, a Rotterdam food demand system is estimated using time series data. The results indicate that over the last 20 years, household consumption has increased for fruit and vegetables, poultry, food eaten away from home, and sweet products, drinks and other foods.... |

| An extension of the Rotterdam model is developed that makes the model’s income flexibility and marginal propensities to consume varying coefficients. Frisch’s duality relationships that the second partial derivatives of demand with respect to income and prices are independent of the order of differentiation are imposed with the marginal propensities to consume specified as functions of income and price, and the Slutsky coefficients specified as functions of income only. A uniform substitute specification is used to analyze the conditional demands for a group of beverages. |

| Using annual Japanese fresh fruit import data from 1971-1997, this study analyzes the import patterns of Japan's seven most popular fresh fruits by implementing and testing a general differential demand system that nests four alternative import demand specifications. When tested against the general system using the five-good case (bananas, grapefruits, oranges, and lemons and aggregating pineapples, berries, and grapes), the analysis rejects the AIDS and NBR specifications, but does not reject Rotterdam and CBS. When estimated using the six-good case (bananas, grapefruits, oranges, lemons, pineapples, and aggregating berries and grapes), the analysis rejects all specifications except the Rotterdam model. |

| Using IRI Infoscan data pertaining to six types of spaghetti sauces and employing an extension of the demand systems framework developed by Duffy, estimates are obtained of own-price, cross-price, and total expenditure elasticities as well as own- and cross-product advertising elasticities. We augment the Duffy model through the use of a polynomial inverse lag mechanism to deal with the carryover effects of advertising. We also account for the impacts of features in newspaper fliers, in-store displays, and coupons. Advertising efforts by industry leaders in spaghetti sauce produce positive own-advertising elasticities (ranging from -.000003 to -.0094). Own-price elasticities are in the elastic range, and nearly all compensated cross-price effects are... |
